The //~AbsolutePosition// property sets or returns the relative record number of a [[Recordset object's|Recordset]] current record.
+!!!Applies to ...
+| !Object |!Description |
+|[[Recordset]] |A set of records derived from a table, a query or an SQL statement. |
+!!!Syntax
+//recordset//{{{.AbsolutePosition}}}
+//recordset//{{{.AbsolutePosition}}} = //value//
+!!!Returned values / Arguments
+{{{Long}}}
+!!!Remarks
+*You can use the //~AbsolutePosition// property to position the current record pointer to a specific record based on its ordinal position in a //Recordset// object. You can also determine the current record number by checking the //~AbsolutePosition// property setting.
+*The //~AbsolutePosition// property value is 1-based (that is, a setting of 1 refers to the first record in the //Recordset// object), you cannot set it to a value greater than or equal to the number of populated records; doing so causes an error. You can determine the number of populated records in the //Recordset// object by checking the [[RecordCount]] property setting. The maximum allowable setting for the //~AbsolutePosition// property is the value of the //~RecordCount// property.<br />Note that in //~MSAccess// the //~AbsolutePosition// property is zero-based (a setting of 0 refers to the 1st record of the //Recordset//).
+*If there is no current record, as when there are no records in the //Recordset// object, //~AbsolutePosition// returns –1. If the current record is deleted, the //~AbsolutePosition// property value isn't defined, and an error occurs if it's referenced.
+*You shouldn't use this property as a surrogate record number. //Bookmarks// are still the recommended way of retaining and returning to a given position and are the only way to position the current record across a //Recordset// object. In particular, the position of a record changes when one or more records preceding it are deleted. There is also no assurance that a record will have the same absolute position if the //Recordset// object is re-created again because the order of individual records within a //Recordset// object isn't guaranteed unless it's created with an SQL statement by using an ORDER BY clause.

(Q) Can I add a "All" option in a combo box on top of the list ?
+
+(R) Use either a special SELECT statement or, alternatively, the [[RowSource]] property to adjust the list.
+
+Assuming next table:
+<<tiddler "CustomersTable">>
+we want to make a combo box listing all //~CompanyName//s.
+!!!(1) Solution with a UNION SELECT statement:
+Define your combo box with the //List content// defined like
+//{{{
+ SELECT "CompanyName" FROM "Customers" UNION SELECT '(All)' as "Bogus" From "Customers" ORDER BY "CompanyName"
+//}}}
+Depending on the database (RDBMS) used above SQL will probably require that the //Type of list contents// entry contains {{{Sql [Native]}}}
+!!!(2) Solution with a bit code
+This solution requires that the list of proposed values remains unchanged as long as the form remains open.
+Additionally it is valid ONLY for LISTBOXES.
+The listbox is defined, exactly as above. Store in the //List content// entry a more usual SQL statement:
+//{{{
+ SELECT DISTINCT "CompanyName" FROM "Customers"
+//}}}
+Note that the code below is also usable if the //~ListBox// is based on a list of values i.o. data in a database table.
+The code, triggered from the form's //When loading// event, will concatenate "(All)" with all values contained in the list.

(Q) How to add a record to a recordset
+
+(R) To add a record to a [[Recordset object|Recordset]]:
+*Use the [[AddNew]] method to create a record you can edit.
+*Assign values to each of the record's fields.
+*Use the [[Update]] method to save the new record.
+The following code example adds a record to a Recordset associated with a table called Shippers.
+<<tiddler "ShippersTable">>
+//{{{
+Dim odbNorthwind As Object
+Dim orsShippers As Object
+
+ Set odbNorthwind = Application.CurrentDb
+ Set orsShippers = odbNorthwind.OpenRecordset("Shippers")
+
+ With orsShippers
+ .AddNew
+ .Fields("CompanyName").Value = "Global Open Source Service"
+ '
+ ' Set remaining fields.
+ '
+ .Update
+ .mClose()
+ End With
+//}}}
+When you use the //~AddNew// method, //~Access2Base// prepares a new, blank record, initializes its fields to their default value and makes it the current record. When you use the //Update// method to save the new record, the record that was current before you used the //~AddNew// method becomes the current record again.
+
+If you use the //~AddNew// method to add a record, and then move to another record or close the //Recordset// without first using the //Update// method, your changes are lost without warning. For example, omitting the ''Update'' method from the preceding example results in no changes being made to the Shippers table.

+|{{{controlname}}} |~|~|The name of a subform of the active form. |
+!!!Remarks
+*The //~ApplyFilter// action must not be called from a [[standalone form|Standalone Forms]].
+*The //~ApplyFilter// action is applied on the current window. To make a window current, use the [[SelectObject]] action. If the current window is neither a form, a table datasheet or a query datasheet, the //~ApplyFilter// action return {{{False}}} and ignores the request.
+*The //~ApplyFilter// action, when applied to a table or a query datasheet, __does NOT work in //~OpenOffice//__ (//~LibreOffice// OK).
+*To apply a filter on a table or a query with //~ApplyFilter//, the table or the query must be open. Eventually use therefore the [[OpenTable]] or [[OpenQuery]] actions.
+*If //controlname// is present, the active window is expected to be a form. Otherwise //~ApplyFilter// refurns {{{False}}} and the request is ignored. The //controlname// is NOT case-sensitive. If //controlname// does not exist in the active form or is not the name of one of its [[subforms|SubForm]] then the action generates a run-time error.
+*When a filter is applied with //~ApplyFilter// the first record (if it exists ...) becomes the current record.
+*Once applied, the filter is preserved for subsequent table or query openings during the same //~LibreOffice/~OpenOffice// session. It will become persistent when the database file ("*.odb") is saved.
+*In the filter argument, record and field names may be surrounded by square brackets. They will be replaced with the correct character surrounding such names in SQL statements targeted to be run on the concerned RDBMS (Relational Database Management System).
+*Giving the null-length string ("") as filter argument resets any pre-existing filter.
+!!!Error messages

+ OpenQuery(cstQueryName)
+ sApplyFilter = "[USUAL NAME] LIKE 'W%'"
+ SelectObject(acQuery, cstQueryName)
+ DoCmd.ApplyFilter(sApplyFilter)
+//}}}
+
+
+
(Q) How can I control when a record is saved in a form ?
+
+(R) Use the form's //Before record change// event to run code each time Base tries to save a record. This way, if the user doesn't want to save a record, you can issue an Undo command instead of saving the record.
+
+For strange reasons the //Before record change// form event is fired twice by //AAO/~LibO// while in most cases one occurrence would be sufficient. That's where the //Recommendation// property becomes useful.
+Read [[Roberto Benitez's Forms and Dialogs document|http://www.baseprogramming.com/FormsAndDialogs.pdf]] about this strange behaviour (p. 20+).
+
+!!!Solution
+Next code will make it. The event fires here a //Function// which will return {{{True}}} only if the modification is confirmed by the user. Otherwise the //Undo// command is run automatically. Other requests for changes (INSERT or DELETE actions) will be accepted blindly.
+//{{{
+Function AskBeforeSave(poEvent As Object) As Boolean
+
+Dim sMsg As String, oEvent As Object
+
+REM MsgBox constants
+Const vbYesNo = 4 ' Yes and No buttons
+Const vbQuestion = 32 ' Warning query
+Const vbYes = 6 ' Yes button pressed
+
+ AskBeforeSave = True

+|Description|Store binary files as base64-encoded tiddlers with fallback links for separate local and/or remote file storage|
+Store or link binary files (such as jpg, gif, pdf or even mp3) within your TiddlyWiki document and then use them as images or links from within your tiddler content.
+> Important note: As of version 3.6.0, in order to //render// images and other binary attachments created with this plugin, you must also install [[AttachFilePluginFormatters]], which extends the behavior of the TiddlyWiki core formatters for embedded images ({{{[img[tooltip|image]]}}}), linked embedded images ({{{[img[tooltip|image][link]]}}}), and external/"pretty" links ({{{[[label|link]]}}}), so that these formatter will process references to attachment tiddlers as if a normal file reference had been provided. |

+|Description|run-time library for displaying attachment tiddlers|
+Runtime processing for //rendering// attachment tiddlers created by [[AttachFilePlugin]]. Attachment tiddlers are tagged with<<tag attachment>>and contain binary file content (e.g., jpg, gif, pdf, mp3, etc.) that has been stored directly as base64 text-encoded data or can be loaded from external files stored on a local filesystem or remote web server. Note: after creating new attachment tiddlers, you can remove [[AttachFilePlugin]], as long as you retain //this// tiddler (so that images can be rendered later on).
+!!!!!Formatters
+<<<
+This plugin extends the behavior of the following TiddlyWiki core "wikify()" formatters:
+* embedded images: {{{[img[tooltip|image]]}}}
+* linked embedded images: {{{[img[tooltip|image][link]]}}}
+* external/"pretty" links: {{{[[label|link]]}}}
+''Please refer to AttachFilePlugin (source: http://www.TiddlyTools.com/#AttachFilePlugin) for additional information.''

+|~CoreVersion|2.1|
+|Type|plugin|
+|Description|Documentation for AttachFilePlugin|
+Store or link binary files (such as jpg, gif, pdf or even mp3) within your ~TiddlyWiki document and then use them as images or links from within your tiddler content.
+!!!!!Inline interface (live)
+>see [[AttachFile]] (shadow tiddler)
+><<tiddler AttachFile>>
+!!!!!Syntax
+<<<
+''To display the attach file control panel, simply view the [[AttachFile]] shadow tiddler that is automatically created by the plugin, and contains an instance of the inline control panel.''. Or, you can write:
+{{{
+<<attach inline>>
+}}}
+in any tiddler to display the control panel embedded within that tiddler. Note: you can actually use any unique identifier in place of the "inline" keyword. Each unique id creates a separate instance of the controls. If the same ID is used in more than one tiddler, then the control panel is automatically moved to the most recently rendered location. Or, you can write:
+{{{
+<<attach>>
+}}}
+(with no ID parameter) in ~SidebarOptions. This adds a command link that opens the controls as a floating panel, positioned directly to the left of the sidebar.
+<<<
+!!!!!Usage
+<<<
+Binary file content can be stored in three different locations:
+#embedded in the attachment tiddler (encoded as base64)
+#on your filesystem (a 'local link' path/filename)
+#on a web server (a 'remote link' URL)
+The plugin creates an "attachment tiddler" for each file you attach. Regardless of where you store the binary content, your document can refer to the attachment tiddler rather than using a direct file or URL reference in your embedded image or external links, so that changing document locations will not require updating numerous tiddlers or copying files from one system to another.
+> Important note: As of version 3.6.0, in order to //render// images and other binary attachments created with this plugin, you must also install [[AttachFilePluginFormatters]], which extends the behavior of the ~TiddlyWiki core formatters for embedded images ({{{[img[tooltip|image]]}}}), linked embedded images ({{{[img[tooltip|image][link]]}}}), and external/"pretty" links ({{{[[label|link]]}}}), so that these formatter will process references to attachment tiddlers as if a normal file reference had been provided. |
+When you attach a file, a tiddler (tagged with<<tag attachment>>) is generated (using the source filename as the tiddler's title). The tiddler contains //''base64 text-encoded binary data''//, surrounded by {{{/%...%/}}} comment markers (so they are not visible when viewing the tiddler). The tiddler also includes summary details about the file: when it was attached, by whom, etc. and, if the attachment is an image file (jpg, gif, or png), the image is automatically displayed below the summary information.
+>Note: although you can edit an attachment tiddler, ''don't change any of the encoded content below the attachment header'', as it has been prepared for use in the rest of your document, and even changing a single character can make the attachment unusable. //If needed, you ''can'' edit the header information or even the MIME type declaration in the attachment data, but be very careful not to change any of the base64-encoded binary data.//
+Unfortunately, embedding just a few moderately-sized binary files using base64 text-encoding can dramatically increase the size of your document. To avoid this problem, you can create attachment tiddlers that define external local filesystem (file://) and/or remote web server (http://) 'reference' links, without embedding the binary data directly in the tiddler (i.e., uncheck "embed data" in the 'control panel').
+
+These links provide an alternative source for the binary data: if embedded data is not found (or you are running on Internet Explorer, which does not currently support using embedded data), then the plugin tries the local filesystem reference. If a local file is not found, then the remote reference (if any) is used. This "fallback" approach also lets you 'virtualize' the external links in your document, so that you can access very large binary content such as ~PDFs, ~MP3's, and even *video* files, by using just a 'remote reference link' without embedding any data or downloading huge files to your hard disk.
+
+Of course, when you //do// download an attached file, the local copy will be used instead of accessing a remote server each time, thereby saving bandwidth and allowing you to 'go mobile' without having to edit any tiddlers to alter the link locations...
+<<<
+!!!!!Syntax / Examples
+<<<
+To embed attached files as images or link to them from other tiddlers, use the standard ~TiddlyWiki image syntax ({{{[img[tooltip|filename]]}}}), linked image syntax ({{{[img[tooltip|filename][tiddlername]]}}}) , or "external link" syntax ({{{[[text|URL]]}}}), replacing the filename or URL that is normally entered with the title of an attachment tiddler.
+
+embedded image data:
+>{{{[img[Meow|tracelog dialog.png]]}}}
+>[img[Meow|tracelog dialog.png]]
+embedded image data with link to larger remote image:
+>{{{[img[click for larger view|tracelog dialog.png][tracelog dialog.png]]}}}
+>[img[click for larger view|tracelog dialog.png][tracelog dialog.png]]
+'external' link to embedded image data:
+>{{{[[click to view attachment|tracelog dialog.png]]}}}
+>[[click to view attachment|tracelog dialog.png]]
+'external' link to remote image:
+>{{{[[click to view attachment|tracelog dialog.png]]}}}
+>[[click to view attachment|tracelog dialog.png]]
+regular ~TiddlyWiki links to attachment tiddlers:
+>{{{[[tracelog dialog.png]]}}} [[tracelog dialog.png]]
+>{{{[[tracelog dialog.png]]}}} [[tracelog dialog.png]]
+<<<
+!!!!!Defining MIME types
+<<<
+When you select a source file, a ''[[MIME|http://en.wikipedia.org/wiki/MIME]]'' file type is automatically suggested, based on filename extension. The AttachFileMIMETypes tiddler defines the list of MIME types that will be recognized by the plugin. Each MIME type definition consists of exactly two lines of text: the official MIME type designator (e.g., "text/plain", "image/gif", etc.), and a space-separated list of file extensions associated with that type. List entries are separated by "----" (horizontal rules).
+<<<
+!!!!!Known Limitations
+<<<
+Internet Explorer does not support the data: URI scheme, and cannot use the //embedded// data to render images or links. However, you can still use the local/remote link definitions to create file attachments that are stored externally. In addition, while it is relatively easy to read local //text// files, reading binary files is not directly supported by IE's ~FileSystemObject (FSO) methods, and other file I/O techniques are subject to security barriers or require additional MS proprietary technologies (like ASP or VB) that make implementation more difficult. As a result, you cannot //create// new attachment tiddlers using IE.
+<<<
+!!!!!Installation
+<<<
+Import (or copy/paste) the following tiddlers into your document:
+* [[AttachFilePlugin]] (tagged with <<tag systemConfig>>)
+* [[AttachFilePluginFormatters]] ("runtime distribution library") (tagged with <<tag systemConfig>>)
+* ~TraceLog Dialog.png and ~TraceLog Dialog.png //(tagged with <<tag attachment>>)//
+* [[AttachFileMIMETypes]] //(defines binary file types)//
+> Important note: As of version 3.6.0, in order to //render// images and other binary attachments created with this plugin, you must also install [[AttachFilePluginFormatters]], which extends the behavior of the ~TiddlyWiki core formatters for embedded images ({{{[img[tooltip|image]]}}}), linked embedded images ({{{[img[tooltip|image][link]]}}}), and external/"pretty" links ({{{[[label|link]]}}}), so that these formatter will process references to attachment tiddlers as if a normal file reference had been provided. |
+<<<
+!!!!!Revisions
+<<<
+2009.06.04 4.0.0 changed attachment storage format to use //sections// instead of embedded substring markers.
+2008.07.21 3.9.0 Fixup for ~FireFox 3: use HTML with separate text+button control instead of type='file' control
+2008.05.12 3.8.1 automatically add 'attach' task to backstage (moved from ~BackstageTweaks)
+2008.04.09 3.8.0 in onChangeSource(), if source matches current document folder, use relative reference for local link. Also, disable 'embed' when using IE (which //still// doesn't support data: URI)
+2008.04.07 3.7.3 fixed typo in HTML for 'local file link' so that clicking in input field doesn't erase current path/file (if any)
+2008.04.07 3.7.2 auto-create AttachFile shadow tiddler for inline interface
+2008.01.08 [*.*.*] plugin size reduction: documentation moved to ...Info
+2007.12.04 [*.*.*] update for ~TW2.3.0: replaced deprecated core functions, regexps, and macros
+2007.12.03 3.7.1 in createAttachmentTiddler(), added optional "noshow" flag to suppress display of newly created tiddlers.
+2007.10.29 3.7.0 code reduction: removed support for built-in upload to server... on-line hosting of binary attachments is left to the document author, who can upload/host files using 3rd-party web-based services (e.g. www.flickr.com, ) or stand-alone applications (e.g., FTP).
+2007.10.28 3.6.0 code reduction: removed duplicate definition of image and prettyLink formatters. Rendering of attachment tiddlers now //requires// installation of AttachFilePluginFormatters
+2007.03.01 3.5.3 use apply() to invoke hijacked function
+2007.02.25 3.5.2 in hijack of "prettyLink", fix version check for ~TW2.2 compatibility (prevent incorrect use of fallback handler)
+2007.01.09 3.5.1 onClickAttach() refactored to create separate createAttachmentTiddler() API for use with ~FileDropPluginHandlers
+2006.11.30 3.5.0 in getAttachment(), for local references, add check for file existence and fallback to remote URL if local file not found. Added fileExists() to encapsulate FF vs. IE local file test function (IE FSO object code is TBD).
+2006.11.29 3.4.8 in hijack for ~PrettyLink, 'simple bracketed link' opens tiddler instead of external link to attachment
+2006.11.29 3.4.7 in readFile(), added try..catch around initWithPath() to handle invalid/non-existent paths better.
+2006.11.09 3.4.6 REAL FIX for ~TWv2.1.3: incorporate new ~TW2.1.3 core "prettyLink" formatter regexp handling logic and check for version < 2.1.3 with fallback to old plugin code. Also, cleanup table layout in HTML (added "border:0" directly to table elements to override stylesheet)
+2006.11.08 3.4.5 TEMPORARY FIX for ~TWv2.1.3: disable hijack of wikiLink formatter due to changes in core wikiLink regexp definition. //Links to attachments are broken, but you can still use {{{[img[TiddlerName]]}}} to render attachments as images, as well as {{{background:url('[[TiddlerName]]')}}} in CSS declarations for background images.//
+2006.09.10 3.4.4 update formatters for 2.1 compatibility (use this.lookaheadRegExp instead of temp variable)
+2006.07.24 3.4.3 in prettyLink formatter, added check for isShadowTiddler() to fix problem where shadow links became external links.
+2006.07.13 3.4.2 in getAttachment(), fixed stripping of newlines so data: used in CSS will work
+2006.05.21 3.4.1 in getAttachment(), fixed substring() to extract data: URI (was losing last character, which broken rendering of SOME images)

+2006.05.20 3.3.6 add "description" feature to easily include notes in attachment tiddler (you can always edit to add them later... but...)
+2006.05.19 3.3.5 add "attach as" feature to change default name for attachment tiddlers. Also, new optional param to specify tiddler name (disables editing)
+2006.05.16 3.3.0 completed ~XMLHttpRequest handling for GET or POST to configurable server scripts
+2006.05.13 3.2.0 added interface for upload feature. Major rewrite of code for clean object definitions. Major improvements in UI interaction and validation.
+2006.05.09 3.1.1 add wikifer support for using attachments in links from "linked image" syntax: {{{[img[tip|attachment1][attachment2]]}}}
+2006.05.09 3.1.0 lots of code changes: new options for attachments that use embedded data and/or links to external files (local or remote)
+2006.05.03 3.0.2 added {{{/%...%/}}} comments around attachment data to hide it when viewing attachment tiddler.
+2006.02.05 3.0.1 wrapped wikifier hijacks in initAttachmentFormatters() function to eliminate globals and avoid ~FireFox 1.5.0.1 crash bug when referencing globals
+2005.12.27 3.0.0 Update for ~TW2.0. Automatically add 'excludeMissing' tag to attachments
+2005.12.16 2.2.0 Dynamically create/remove attachPanel as needed to ensure only one instance of interface elements exists, even if there are multiple instances of macro embedding.
+2005.11.20 2.1.0 added wikifier handler extensions for "image" and "prettyLink" to render tiddler attachments
+2005.11.09 2.0.0 begin port from old ELS Design adaptation based on ~TW1.2.33

(Q) Can I list the value of all controls on a form for debugging purposes ?
+
+(R) Use the [[Controls]] collection on objects and nested objects recursively as shown.
+
+Consider next tables:
+<<tiddler "OrdersTable">>
+<<tiddler "OrderDetailsTable">>
+Define a main/sub form based on those tables (wizard is perfect for making the form ...: choose a normal format for the mainform and the grid format for the subform).
+
+Run next code:
+//{{{
+Sub StartBrowseThruControls(ByVal psFormName As String)
+
+Dim oMainForm As Object
+ Set oMainForm = Forms(psFormName)
+ BrowseThruControls(oMainForm)
+
+End Sub
+
+Sub BrowseThruControls(poObject As Object, ByVal Optional piLevel As Integer)
+
+Dim i As Integer, ocControl As Object
+ If IsMissing(piLevel) Then piLevel = 1
+ For i = 0 To poObject.Controls.Count - 1
+ Set ocControl = poObject.Controls(i)
+ Select Case ocControl.SubType
+ Case "SUBFORMCONTROL"
+ DebugPrint piLevel, ocControl.SubType, ocControl.Name
+ BrowseThruControls(ocControl.Form, piLevel + 1)
+ Case "GRIDCONTROL"
+ DebugPrint piLevel, ocControl.SubType, ocControl.Name
+ BrowseThruControls(ocControl, piLevel + 1)
+ Case Else
+ If ocControl.hasProperty("Value") Then DebugPrint piLevel, ocControl.SubType, ocControl.Name, ocControl.Value
+ End Select
+ Next i

(Q) How do I simulate a calculated field on a form ? //AOO/~LibO// does not support such fields in forms while //~MSAccess// does.
+
+(R)
+*Make the calculated field {{{Enabled = False}}} in the Control properties sheet.
+*Compute its content in the "After record Change" event.
+
+Let's consider next tables:
+<<tiddler OrdersTable>>
+<<tiddler OrderDetailsTable>>
+The goal is to have a form linked to the {{{Orders}}} table in which a //~SumOfDetails// calculated field contains the sum of the orders as found in the {{{Order Details}}} child records, computed as:
+//{{{
+[Order Details].[UnitPrice] * [Order Details].[Quantity] * (1 - [Order Details].[Discount])
+//}}}
+!!!(1) Solution by computing the field in Basic
+Store next code in the "After record Change" event of the form :
+//{{{
+Sub ComputeOrderTotal(poEvent As Object)
+Dim oeEvent As Object, ofForm As Object, ocSum As Object, vOrderId As Variant
+ Set oeEvent = Events(poEvent)
+ If Not IsNull(oeEvent) Then
+ Set ofForm =oeEvent.Source
+ vOrderId = ofForm.Controls("OrderID").Value
+ If Not IsEmpty(vOrderId) Then
+ Set ocSum = ofForm.Controls("SumOfDetails")
+ ocSum.Value = DSum("[Order Details].[UnitPrice] * [Order Details].[Quantity] * (1 - [Order Details].[Discount])" _
+ , "[Order Details]", "[Order Details].[OrderID]=" & vOrderId)
+ End If
+ End If
+End Sub
+//}}}
+!!!(2) Solution with SQL only
+This solution is preferable whenever possible.
+To have an idea of the functions built in HSQLDB, look at [[HSLQB Built-in functions|http://wiki.openoffice.org/wiki/Built-in_functions_and_Stored_Procedures]].
+Associate the form with next SQL command and the Calculated field with the //~TotalOrder// database field :
+//{{{
+SELECT "Orders"."OrderID", "Orders"."OrderDate", "Orders"."ShipAddress", "Orders"."ShipCity",
+ SUM( "Order Details"."UnitPrice" * "Order Details"."Quantity" * ( 1 - "Order Details"."Discount" ) ) AS "TotalOrder"
+ FROM "Order Details", "Orders" WHERE "Order Details"."OrderID" = "Orders"."OrderID"
+ GROUP BY "Orders"."OrderID", "Orders"."OrderDate", "Orders"."ShipAddress", "Orders"."ShipCity"

(Q) Can a numeric field be edited thru a Calculator widget like Base forms propose a Calendar widget for date fields ?
+
+(R) A calculator can be implemented as a [[Dialog]]. When the dialog is closed the computed result is copied into the concerned form field.
+
+The solution must implement a //as easy as possible// programming AND user interface from the initial form event activating the calculator up to the final copy of the result into the numeric form field.
+See the suggested implementation in the //Calculator// form of the provided examples database: a button with a nice calculator icon opens the dialog.
+
+Steps:
+!!!!Make a form containing the targeted numeric fields and one button by such field.
+Link the //Execute action// event of each button with a macro similar to next one. One macro by each field/button pair.
+//{{{
+Sub StartCalculator(poEvent As Object)
+' StartCalculator should be adapted to user's need:
+' - it is assumed to be activated from an appropriate button
+' - the field to compute is assumed in the same form or subform as the button
+' - the field to compute must be of type NUMERICFIELD or CURRENCYFIELD
+' - the name of the field to compute should be set in next line
+' - The 3rd argument is optional. True = initialize calculator with field current value
+
+ Call StartCalcDialog(poEvent, "TargetCalcField", True)
+
+End Sub
+//}}}
+Of course adapt the code to your needs !
+!!!!--Design a calculator such as-- ... Export and re-import next calculator dialog ...
+[img[calculator.png]]
+!!!!The code behind the //~StartCalcDialog// Sub
+The code is stored in the //Calculator// module of the provided example file. It is inspired by an old [[sample code from Microsoft|http://groups.engin.umd.umich.edu/CIS/course.des/cis400/vbasic/calcode.txt]].
+It is generic enough to adapt the display of the decimal point to the locale settings.
+
+1. The current status of the Calculator is constantly maintained in next variables
+//{{{
+Type CalcBuffer

+ LocalePoint As String ' Local decimal point
+End Type
+
+Public gCalc As CalcBuffer
+Const cstStdFormat = "General Number" ' Format of display in calculator
+//}}}
+2. Next Sub (the core Sub) checks the arguments, manages the display of the dialog window, and copies the result in the original numeric field if the OK button is pressed:
+//{{{
+Sub StartCalcDialog(poEvent, ByVal psFieldName As String, Optional ByVal pbCopy As Boolean)

+//}}}
+3. The calculator should react to each activation of any button in the dialog box. Link all buttons - except //OK// and //Cancel// - //Execute action// event to next Sub:

This page details the conventions used in the coding of the //~Access2Base// API.
+!!Library and Modules
+*The acConstants module lists constants that are used in the API. They are defined as //Global//. Their name is identical as in ~MSAccess. Their value is in most cases identical to that of ~MSAccess, however not always. The scope of global constants is limited to one single library. As a consequence their definition may freely be copied and pasted to make them available in user libraries.
+*The reserved words are //~Proper-Cased// showing the same appearance as in the IDE of ~MSAccess.
+!!Functions and Subroutines
+*~OpenOffice/~LibreOffice ignores the Private/Public attribute in Functions or Subs declarations. Nevertheless the attribute must be present. Rules for use are:
+| !Attribute | !Sub/Function Naming | !When |
+|Public |Starts with a letter |The Sub/Function belongs to the ~Access2Base API. As such it may be called from any other library developed by the user. |
+|Public |Starts with an underscore "_" |The Sub/Function must be called only from within the ~Access2Base library. As such it MUST NOT be called from another library as there is no guarantee about the arguments, the logic or even the existence of that piece of code in a later release. |
+|Private |The Sub/Function must start with an underscore "_" |The Sub/Function must be called only from the module in which it is located |
+*Functions and Subroutines belonging to the API (= "standard" functions/Subs) are defined in their module in alphabetical order.
+*Functions and Subroutines not belonging to the API are defined in their module in alphabetical order below the standard ones.
+*The return value of a function is always declared explicitly.
+*The parameters are always declared explicitly even if they're variants.
+*The Function and Sub declarations start at the 1^^st^^ column of the line.
+*The End Function/Sub statement is followed by a comment reminding the name of the function or sub.
+!!Variable declarations
+*The //Option Explicit// statement is mandatory in every module.
+*The Global, Dim and Const statements always start in the first column of the line.
+*The type (Dim ... As ..., Function ... As ...) is always declared explicitly, even if the type is Variant.
+*Variables are //~Proper-Cased//. They are always preceded by a lower-case letter indicating their type. With next exception: variables i, j, k, l, m and n must be declared as integers.
+| !First letter | !Type |
+| b |Boolean |
+| d |Date |
+| v |Variant |
+| o |Object |
+| i |Integer |
+| l |Long|
+| s |String |
+{{indent{Example:{{{ Dim sValue As String}}}
+*Parameters are preceded by the letter //p// which itself precedes the single typing letter. Like in:<br />{{{Public Function MyFunction(psValue As String) As Variant}}}
+*Object variables are preceded by the letter o followed by their type:
+| !First letter | !Type |
+| db |Database |
+| f |Form or Subform |
+| c |Control |
+| e |Event |
+| p |Property |
+{{indent{like in:{{{ Dim ocControl As Object}}}
+*Global variables in the ~Access2Base library are ALL preceded by an underscore "_" as NONE of them should be invoked from outside the library.
+*Constant values with a local scope are //~Proper-Cased// and preceded by the letters //cst//.
+*Constants with a global scope are //~UPPER-CASED//
+Example
+//{{{
+Global Const ACONSTANT = "This is a global constant"
+Function MyFunction(pocControl As Object, piValue) As Variant
+Dim iValue As Integer
+Const cstMyConstant = 3
+//}}}
+!Goto
+The //Goto// statement is forbidden.
+It is however highly recommended for __error__ and __exception__ handling.

+*The copy of the table structure is done

(Q) How can I know the number of records in a //Recordset// object ? For example, I may want to create a form that shows how many records are in each of the tables in a database. Or I may want to change the appearance of a form or report based on the number of records it includes.
+
+(R) The [[RecordCount]] property contains the number of records in a [[Recordset]]. A //Recordset object// with no records has a //~RecordCount// property value of 0.
+
+However:
+>The value of the //~RecordCount// property equals the number of records that have actually been accessed. To visit all the records, use the [[MoveLast|Move (recordset)]] method immediately after opening the //Recordset//, then use [[MoveFirst|Move (recordset)]] to return to the first record. This is not done automatically because it may be slow, especially for large result sets.
+
+The following code example creates a //Recordset// object, and then determines the number of records in the //Recordset//.
+//{{{
+Function FindRecordCount(sSQL As String) As Long
+
+Dim odbNorthwind As Object
+Dim orsRecords As Object
+On Local Error GoTo ErrorHandler
+
+ Set odbNorthwind = Application.CurrentDb
+ Set orsRecords = odbNorthwind.OpenRecordset(sSQL)
+ With orsRecords
+ If .EOF Then
+ FindRecordCount = 0
+ Else

+ FindRecordCount = .RecordCount
+ End If
+ .mClose
+ End With
+
+ Set orsRecords = Nothing
+ Set odbNorthwind = Nothing
+ Exit Function
+
+ErrorHandler:
+ TraceError("ERROR", Err, "FindRecordCount", Erl)
+End Function
+//}}}
+As your application deletes records in a //Recordset//, the value of the //~RecordCount// property decreases. However, in a multiuser environment, records deleted by other users are not reflected in the value of the //~RecordCount// property. Using the //~MoveFirst// method on a //Recordset//, followed by the //~MoveLast// method, resets the //~RecordCount// property to the current total number of records in the //Recordset//.

+*The //dbAutoIncrField// attribute MUST NOT be set when the //~CreateField// method is applied on an existing table. It is valid only between the [[CreateTableDef]] and [[Add]] methods.
+*When the //dbAutoIncrField// attribute is present (for a new table only ...) the field is created and becomes the primary key of the table. The __auto-increment__ attribute of the newly created primary key will be applied only if the RDBMS and the currently used driver allow it. As an example, for the embedded HSQLDB database, the attribute will be applied, for a [["splitted" HSQLDB database|http://www.oooforum.org/forum/viewtopic.phtml?p=396523#396523]], it might not be applied.
+*When the //dbAutoIncrField// attribute is not present the newly created field is "nullable", i.e. when not initialized it gets the {{{Null}}} value as default.
+*If additional attributes are needed to specify the new field more accurately, use an SQL statement given as argument to the [[RunSQL action|RunSQL]].
+*The //~CreateField// method must not be invoked from a [[standalone form|Standalone Forms]] defined in a non-Base (Writer, Calc, ...) document.
+*Instead of using the numeric values for ~DbType, one may copy next code and paste it in his/her own code. This allows to use symbolic names, close to or identical with the field types existing in ~MSAccess.

(Q) How can I write a query similar to the crosstab queries I find in ~MSAccess (also elsewhere) ? To produce something like:
+| No. Sales per year | 1996 | 1997 | 1998 | Total |
+|Margaret Peacock | 31 | 81 | 44 | 156 |
+|Janet Leverling | 18 | 71 | 38 | 127 |
+|Nancy Davolio | 26 | 55 | 42 | 123 |
+|Laura Callahan | 19 | 54 | 31 | 104 |
+|Andrew Fuller | 16 | 41 | 39 | 96 |
+|etc ... |||||
+
+(R) A crosstab query aggregates data in the form of a matrix. Example: products sales by period. The issue is that the periods to be considered are in the database and can vary over time. Additionally periods can be years, quarters, months, ...
+Doing this is feasible by //generating// with a Basic function the appropriate SQL statement.
+
+The solution presented here will work for the SUM() and COUNT() aggregate functions.
+
+Let's consider next tables:
+<<tiddler "ProductsTable">>
+<<tiddler "CustomersTable">>
+<<tiddler "OrdersTable">>
+<<tiddler "OrderDetailsTable>>
+
+A crosstab query needs at least next inputs:
+*One or more __row headings__: several database fields which will appear in front of each row and on which the aggregation function will be applied => [Rowheadings]] or their aliases
+*One __column heading__: the field varying horizontally (periods, ...) => (~ColHeading] or its alias
+*The (numeric) __value__ which will be aggregated => [Aggregate]
+*The __FROM expression__ listing the concerned tables and the associated WHERE clause => [~FromExpression]
+*and, optionally, one or more sort keys.
+
+The target is to produce an SQL statement which will look like:
+//{{{
+ SELECT
+ [RowheadingAlias(0)],
+ [RowheadingAlias(1)],
+ ...
+ SUM( CASE [ColHeadingAlias] WHEN 'ColValue0' THEN [Data] ELSE 0 END ) As [ColValue0],
+ SUM( CASE [ColHeadingAlias] WHEN 'ColValue1' THEN [Data] ELSE 0 END ) As [ColValue1],
+ SUM( CASE [ColHeadingAlias] WHEN 'ColValue2' THEN [Data] ELSE 0 END ) As [ColValue2],
+ ...
+ SUM( [Data] ) As [All]
+ FROM
+ (SELECT RowHeading(0),
+ RowHeading(1),
+ ...
+ ColHeading,
+ Aggregate As [Data]
+ FROM FromExpression
+ GROUP BY RowHeadingAlias(0),RowHeadingAlias(1), ColHeadingAlias
+ )
+ GROUP BY RowHeadingAlias(0),RowHeadingAlias(1)
+ ORDER BY [All] | OrderBy
+//}}}
+The resulting SQL statement could be afterwards:
+*displayed with the [[OpenSQL]] action
+*browed as a [[Recordset]]
+*stored as a new Query with [[CreateQueryDef]]
+!!!Examples:
+//{{{
+Dim sSql As String
+ sSql = MakeCrossTab( _
+ "[FirstName] || ' ' || [LastName] As [Name]" _
+ , "YEAR([OrderDate]) || 'Q' || QUARTER([OrderDate]) As [Quarter]" _
+ , "Count(*)" _
+ , "[Employees] INNER JOIN [Orders] ON ([Employees].[EmployeeID]=[Orders].[EmployeeID])" _
+ , "DESC" _
+ )
+ OpenSQL(sSql, dbSQLPassThrough)
+//}}}
+will produce:
+| Name | 1996Q3 | 1996Q4 | 1997Q1 | 1997Q2 | 1997Q3 | 1997Q4 | 1998Q1 | 1998Q2 | All |

+|Steven Buchanan | 4 | 7 | 3 | 4 | 6 | 5 | 12 | 1 | 42 |
+Similarly:
+//{{{
+Dim sSql As String
+Const dbSQLPassThrough = 64
+ sSql = MakeCrossTab( _
+ "[Customers].[CompanyName] As [Customer], [Products].[ProductName] AS [Name]" _
+ , "YEAR([OrderDate]) || 'Q' || QUARTER([OrderDate]) As [Quarter]" _
+ , "SUM([Order Details].[UnitPrice]*[Quantity]*(1-[Discount]))" _
+ , "[Order Details], [Products], [Orders], [Customers] " _
+ & "WHERE [Order Details].[ProductID] = [Products].[ProductID] " _
+ & "AND [Order Details].[OrderID] = [Orders].[OrderID] " _
+ & "AND [Customers].[CustomerID] = [Orders].[CustomerID] " _
+ & "AND YEAR([Orders].[OrderDate]) = 1997" _
+ , "[Customer]" _
+ )
+ OpenSQL(sSql, dbSQLPassThrough)

(Q) How can I write a function that computes the //median// value of a range of data ?
+
+(R) The median is the numerical value separating the higher half of a data sample from the lower half. The median of a finite list of numbers can be found by arranging all the observations from lowest value to highest value and picking the middle one. If there is an even number of observations, then there is no single middle value; the median is then usually defined to be the mean of the two middle values. (Wikipedia)

(Q) Can I hide the database window ?
+
+(R) No, the database window cannot be hidden. It can however be minimized.
+
+What is called here the //database window// is the screen welcoming the user when (s)he opens a database front-end file (suffixed with ".odb") where the tables, queries, forms and reports are listed.
+It can be desirable to hide that window and, instead, opening a form for example.
+!!!Minimize the database window
+Very easy code but it's as easy for the user to restore it with a mouse click. Nevertheless ... first select the //database window// then minimize it.
+//{{{

(Q) How could I get data stored in a database from within a Calc cell formula ?
+
+(R) Calc offers as a standard feature to insert data from database tables and queries via a specific browser that is invoked by using the {{{View}}} + {{{Data Sources}}} menu command or the {{{F4}}} function key.
+The Help files describe in detail how to proceed.
+However the question here is, as an example : how is it possible to enter a ''product code'' in a cell and get in another calculated cell its ''description'', knowing that the __correspondence between both fields is somewhere in a database table__ and not in the spreadsheet ?
+
+Obviously, to not simplify the problem, we would appreciate to have things happen automatically, i.e. also when the sheet is configured to have its
+>{{{Tools + Cell Contents}}}
+set to ''{{{AutoCalculate}}}'', and __without useless database accesses__.
+
+In the proposed solution we will go even further. The example shown will illustrate next 4 functionalities:
+*Use database data to populate a dropdown listbox.
+*Derive automatically the //description// from the selected item in the listbox.
+*Prepare a report with the heading derived from the database table field names.
+*Populate an array of data in the sheet extracted from the database and filtered by the choice in the dropdown box..
+[img[Access data dynamically from a Calc spreadsheet|dbaccess_from_calc.png]]
+!!A solution
+Let's consider next tables:
+<<tiddler "CategoriesTable">>
+<<tiddler "ProductsTable">>
+The final purpose of the spreadsheet is to list all products belonging to the category selected by the user.
+!!!Preamble
+The challenge will be to do next things apparently simultaneously without the user becoming aware of the underlying complexity:
+*to load the ~Access2Base macro library, only once
+*to open the database file (".odb") referring to the effective database, also only once
+*to extract the needed data only when relevant and every time it is, i.e. when some input parameter has been modified.
+When Calc recomputes a worksheet, it sequences its computations in function of the respective arguments present in each cell formula.
+For example, if
+**cell A1 is a number
+**C1 contains the formula {{{"=A1*2"}}}
+**and B1 contains the formula {{{"=C1*C1"}}}
+the worksheet will not be recomputed from left to right, but in the sequence A1, C1, B1. In addition, C1 and B1 will be both recomputed automatically every time A1 receives another value.
+Choosing in this matter either cells or "names" (defined by {{{Insert}}} + {{{Names}}}) does not make any difference. Names will be preferred if they do not need to be visible in the sheet.
+The sequencing of computations done by Calc is the mean we will use to reach our challenge.
+!!!Global
+To access the database we have to make use of a database object. Let's define it as a {{{Global}}} variable.
+Such variables remain in life as long as
+*the AOO/~LibO session is lasting
+*the module where it is declared is not edited.
+Usually I declare {{{Global}}} variable in a separate module as such a module is unlikely to be modified often.
+//{{{
+Global oMyDatabase As Variant
+//}}}
+!!!Define Name
+Define a {{{Name}}} called {{{IsConnected}}}. Store in it the formula
+//{{{
+=DBCONNECTED()
+//}}}
+DBCONNECTED is a user-defined function and behaves exactly like any builtin Calc function or expression. It has no argument.
+The code of the function is here:
+//{{{
+Sub _Init()
+Dim oLib As Object
+ Set oLib = GlobalScope.BasicLibraries
+ If oLib.hasByName("Access2BaseDev") Then
+ oLib.loadLibrary("Access2BaseDev")
+ ElseIf Not oLib.IsLibraryLoaded("Access2Base") Then
+ oLib.loadLibrary("Access2Base")
+ End If
+ If oLib.hasByName("XrayTool") Then oLib.loadLibrary("XrayTool")
+ Set oMyDatabase = Nothing
+End Sub
+
+Function DBConnected() As Variant
+Dim sCalc As String, sDatabase As String
+ DBConnected = 0
+ If IsEmpty(oMyDatabase) Or IsNull(oMyDatabase) Then
+ Call _Init() ' Load Basic libraries
+ With ThisComponent
+ sCalc = Join(Split(.Title, " "), "%20") ' Replace " " by "%20" in current filename
+ sDatabase = Join(Split(.URL, sCalc), "TT%20NorthWind.odb") ' Build URL of database located in same directory as current file
+ End With
+ Set oMyDatabase = OpenDatabase(sDatabase)
+ End If
+ DBConnected = 1
+End Function
+//}}}
+The result is that the loading of the library is put on the computation path. There is no reason why Calc would require recomputation several times of {{{IsConnected}}} except while loading the spreadsheet.
+Now we can build other formulas, like:
+//{{{
+=IF(IsConnected;USERDEFINED(...);False)
+//}}}
+being sure that __such formulas will be evaluated by Calc only when the evaluation of {{{IsConnected}}} has been achieved__.
+!!!Setup the dropdown box
+Use the {{{Data}}} + {{{Validity}}} menu commands to define //Criteria// as being a //Cell range//, select the //Show selection list// checkbox and enter as //Source// next formula
+//{{{
+=IF(IsConnected;CATEGORIESLIST();"")
+//}}}
+The CATEGORIESLIST() function:
+//{{{
+Function CategoriesList() As Variant
+' Return the list of available product categories as an array
+Dim oRs As Object, sCatsRC() As Variant, sCats() As Variant, i As Integer
+ If Not IsNull(oMyDatabase) Then
+ Set oRs = oMyDatabase.OpenRecordset("SELECT [CategoryName] FROM [Categories] ORDER BY [CategoryName]")
+ sCatsRC = oRs.GetRows(1000) ' matrix (column, row)
+ sCats() = Array() ' Reduce to column only
+ ReDim sCats(0 To UBound(sCatsRC, 2))
+ For i = 0 To UBound(sCats)
+ sCats(i) = sCatsRC(0, i)
+ Next i
+ CategoriesList = sCats()
+ oRs.mClose()
+ End If
+End Function
+//}}}
+!!!Find description
+The dropdown box is in cell {{{B2}}}. We put in cell {{{D2}}} next formula:
+//{{{
+=IF(IsConnected;CATLOOKUP(B2);"")
+//}}}
+that will be recomputed by Calc each time the cell {{{B2}}} is modified by the user.
+The CATLOOKUP function:
+//{{{
+Function CatLookup(ByVal pvArg As Variant) As Variant
+ If Not IsNull(oMyDatabase) Then CatLookup = oMyDatabase.DLookup("[Description]", "[Categories]", "[CategoryName]='" & pvArg & "'")
+End Function
+//}}}
+!!!Fill the data
+The data matrix will be inserted as an ''array formula'' ({{{Ctrl}}} + {{{Shift}}} + {{{Enter}}}) in cells {{{D6:H35}}}. Look at the AOO/~LibO help to know more about them.
+//{{{
+{=IF(IsConnected,PRODUCTSLOAD($B$2),"")}
+//}}}
+The PRODUCTSLOAD function:
+//{{{
+Function ProductsLoad(ByVal pvCat As Variant) As Variant
+Dim oRS As Object, sSQL As String, vResult() As Variant, vTranspose() As Variant
+Dim i As Integer, j As Integer
+Const cstSize = 30
+ If Not IsNull(oMyDatabase) Then
+ sSQL = "SELECT [ProductName] AS [Product], [QuantityPerUnit] AS [Quantity], [UnitsInStock] AS [Stock], [UnitPrice] AS [Price]" _
+ & ", [CompanyName] AS [Company]" _
+ & " FROM [Products], [Categories], [Suppliers]" _
+ & " WHERE [Products].[CategoryID] = [Categories].[CategoryID]" _
+ & " AND [Suppliers].[SupplierID] = [Products].[SupplierID]" _
+ & " AND [Categories].[CategoryName] = '" & pvCat & "'" _
+ & " ORDER BY [Product] ASC"
+ Set oRS = oMydatabase.Openrecordset(sSQL)
+ ' Enumerate field names
+ vFields() = Array() ' Mandatory before resizing a variant
+ ReDim vFields(0 To oRS.Fields.Count - 1)
+ For i = 0 To UBound(vFields)
+ vFields(i) = oRS.Fields(i).Name
+ Next i
+ ' fetch recordset data
+ vResult() = oRS.GetRows(cstSize)
+ oRS.mClose()
+ ' Transpose results

+ Next j
+ Next i
+
+ ProductsLoad = vTranspose()
+ End If
+End Function
+//}}}
+A second {{{Global}}} variable is used here to store the field names in a more generic way:
+//{{{
+Global vFields() As Variant
+//}}}
+!!!Headings
+The title of the data matrix is again an array formula, put in cells {{{D4:H4}}}.
+The {{{G36>0}}} condition below makes that the heading cells are evaluated after the data cells. Indeed titles are extracted from the database in the same {{{Sub}}} as the data.
+//{{{
+{=IF(AND(IsConnected,G36>0),DBTITLE(),"")}
+//}}}
+associated with next code:
+//{{{
+Function DbTitle() As Variant
+ If Not IsNull(oMyDatabase) Then
+ DbTitle() = vFields()
+ End If
+End Function
+//}}}
+!!!Close the connection
+Finally it is always recommended to clean the connection to the database.
+Associate next code
+//{{{
+Function DbClose()
+ If Not IsNull(oMyDatabase) Then oMyDatabase.mClose()
+ Set oMyDatabase = Nothing ' Reinitialize oMyDatabase to Null

!!!Introduction
+~Access2Base uses internally an error handler that can be optionally used by users in their own code.
+The principles are:
+*An error has an __error-level__. The error-level determines the severity of the error and the behaviour of the program after the error trap: stop or go ahead ?
+*All errors, whatever their level, can be registered on the request of the programmer. The technique used by ~Access2Base is to keep the error //traces// in memory through a //circular buffer//, i.e. a buffer where the oldest entries are replaced by the new ones when the buffer gets full.
+*The error traces (circular buffer) can be viewed for debugging purposes in what is called the ''~Access2Base Console'' dialog box.
+*All the user-defined Subs or Functions follow the same code structure for error handling.
+!!!To view the errors log
+*If //~Access2Base// is included in the software, run next code, either directly in the Basic IDE or via a toolbar button, or ...
+//{{{
+Sub Console()
+ TraceConsole()
+End Sub
+//}}}
+*If //~Access2Base// has been installed as a separate extension, then execute next menu command
+>{{{Tools + Add-Ons + Access2Base Console ...}}}
+in the Basic IDE.
+!!!API
+The routines for error handling are:
+|[[TraceConsole]] |Open the //Console// dialog box for display of all past errors and logs. |
+|[[TraceError]] |Report an error found. |
+|[[TraceLevel]] |Set the minimal level of errors to be reported in the console. |
+|[[TraceLog]] |Log an event in the circular buffer if its level is at least equal to the minimal error level. |
+|DebugPrint |Record as many values as wanted in tabular form in the circular buffer, typically for debugging. |
+!!!Error levels
+| !Level | !Type |!Description |
+|"DEBUG" | String |To report values of variables during the program execution. Such reported errors are NOT user visible. |
+|"INFO" |~|To report any event |
+|"WARNING" |~|To report some abnormal event. |
+|"ERROR" |~|To report an error trapped by a user program. |
+|"FATAL" |~|To report an error caused by a user program but detected by ~Access2Base (f.i. "Form does not exist ..." etc.). |
+|"ABORT" |~|To report an error inside the ~Access2Base API itself. Do not use for programmer or user errors. |
+!!!Recommended program structure for error handling
+The example is given for a //Sub//. It is, mutatis mutandis, equally valid for a //Function//.
+//{{{
+Sub mySub
+ On Local Error Goto Error_Sub
+ ...
+Exit_Sub:
+ Exit Sub
+Error_Sub:
+ TraceError("ERROR", Err, "MySub", Erl)
+ Goto Exit_Sub
+End Sub
+//}}}
+In case of error next message will be displayed to the user and simultaneously registered in the trace buffer:
+>Error # //number// (//...description...//) occurred at line //line// in mySub.
+
+
+
+

(Q) How can I list table and field names, and use them in my code ?
+
+(R) We will present 2 techniques. a generic one which uses the ~Access2Base API for exploring //~TableDefs//, and a second, which is specific to HSQLDB, which runs SQL statements on the database schema.
+
+!!!An easy solution is to use the [[TableDefs]] and [[Fields]] collections and their objects.
+Here a simple list of tables with their fields and types:
+//{{{
+Sub ScanTables()
+
+Dim oDatabase As Object, oTable As Object, oField As Object
+Dim i As Integer, j As Integer
+
+ Set oDatabase = Application.CurrentDb()
+ With odatabase
+ For i = 0 To .TableDefs.Count - 1
+ Set oTable = .TableDefs(i)
+ DebugPrint oTable.Name
+
+ For j = 0 To oTable.Fields.Count - 1
+ Set oField = oTable.Fields(j)
+ DebugPrint "", LongStr(oField.Name), LongStr(oField.TypeName), oField.Size
+ Next j
+ Next i
+ End With
+
+End Sub
+
+Function LongStr(psString As String) As String
+Const cstLength = 20
+ LongStr = Left(psString & Space(cstLength), cstLength)
+End Function
+//}}}
+Note that the //~LongStr// function is there only to have the output cleanly aligned in columns.
+The output will be something like:
+//{{{
+ Categories
+ CategoryName VARCHAR 50
+ Description VARCHAR 2147483647
+ Picture BINARY 2147483647
+ CategoryID BIGINT 0
+ Customers
+ Address VARCHAR 50
+ City VARCHAR 50
+ CompanyName VARCHAR 50
+ ContactName VARCHAR 50
+ ContactTitle VARCHAR 50
+ Country VARCHAR 50
+ CustomerID VARCHAR 50
+ Fax VARCHAR 50
+ Phone VARCHAR 50
+ PostalCode VARCHAR 50
+ Region VARCHAR 50
+ Employees
+ Address VARCHAR 50
+ etc ...
+//}}}
+!!!Solution by exploring the database schema directly (HSQLDB only)
+Not surprisingly __reading the HSQLDB documentation__ will help understand the following examples.
+Running next code
+//{{{
+Sub ScanSchemaSQL()
+Dim sSql As String
+ sSql = "SELECT [TABLE_NAME],[COLUMN_NAME],[SYSTEM_COLUMNS].[TYPE_NAME],[COLUMN_SIZE] " _
+ & "FROM [INFORMATION_SCHEMA].[SYSTEM_TABLES],[INFORMATION_SCHEMA].[SYSTEM_COLUMNS] " _
+ & "WHERE [TABLE_SCHEM]='PUBLIC' AND [SYSTEM_COLUMNS].[TABLE_NAME]=[SYSTEM_TABLES].[TABLE_NAME]"
+ OpenSQL(sSql, dbSQLPassThrough)
+End Sub
+//}}}
+produces the result displayed below:
+//{{{
+TABLE_NAME COLUMN_NAME TYPE_NAME COLUMN_SIZE
+Categories CategoryName VARCHAR 50
+Categories Description VARCHAR 2147483647
+Categories Picture BINARY 2147483647
+Categories CategoryID BIGINT
+Customers Address VARCHAR 50
+Customers City VARCHAR 50
+Customers CompanyName VARCHAR 50
+Customers ContactName VARCHAR 50
+Customers ContactTitle VARCHAR 50
+Customers Country VARCHAR 50
+Customers CustomerID VARCHAR 50
+Customers Fax VARCHAR 50
+Customers Phone VARCHAR 50
+Customers PostalCode VARCHAR 50
+Customers Region VARCHAR 50
+Employees Address VARCHAR 50
+etc ...
+//}}}
+The same results can also be explored programmatically:
+//{{{
+Sub ScanSchema()
+
+Dim oRecordset As Object, sSql As String, iNbFields As integer
+ sSql = "SELECT [TABLE_NAME],[COLUMN_NAME],[SYSTEM_COLUMNS].[TYPE_NAME],[COLUMN_SIZE] " _
+ & "FROM [INFORMATION_SCHEMA].[SYSTEM_TABLES],[INFORMATION_SCHEMA].[SYSTEM_COLUMNS] " _
+ & "WHERE [TABLE_SCHEM]='PUBLIC' AND [SYSTEM_COLUMNS].[TABLE_NAME]=[SYSTEM_TABLES].[TABLE_NAME]"
+
+ Set oRecordset = Application.CurrentDb().OpenRecordset(sSql, , dbSQLPassThrough, dbReadOnly)
+ With oRecordset
+ iNbFields = .Fields.Count
+ Do While Not .EOF()
+ DebugPrint LongStr(.Fields("TABLE_NAME").Value) _
+ , LongStr(.Fields("COLUMN_NAME").Value) _
+ , LongStr(.Fields("TYPE_NAME").Value) _
+ , .Fields("COLUMN_SIZE").Value
+ .MoveNext()
+ Loop
+ End With
+
+End Sub
+//}}}
+produces once again the same result as before ...
+//{{{

(Q) How do I get data from a database table into my Basic application ?
+
+(R) After you have located a particular record or records, you may want to extract data to use in your application. 2 methods are proposed: a single value or bulk data.
+
+Let's consider next table:
+<<tiddler "OrdersTable">>
+!!!Copying a Single Field
+You can copy a single field of a record to a variable of the appropriate data type. The following example extracts three fields from the first record in a [[Recordset object|Recordset]].
+//{{{
+Dim odbNorthwind As Object
+Dim orsOrders As Object
+Dim dOrderDate As Date
+Dim sShipAddress As String
+Dim sShipCity As String
+
+ Set odbNorthwind = Application.CurrentDb
+ Set orsOrders = odbNorthwind.OpenRecordset("Orders")
+
+ With orsOrders
+ .MoveFirst
+ dOrderDate = .Fields("OrderDate").Value
+ sShipAddress = .Fields("ShipAddress").Value
+ sShipCity = .Fields("ShipCity").Value
+ .mClose()
+ End With
+//}}}
+!!!Copying Entire Records to an Array
+To copy one or more records, you can create a two-dimensional array and copy records one at a time. You increment the first subscript for each record and the second subscript for each field.
+A fast way to do this is to use the [[GetRows method|GetRows]], which returns a two-dimensional array. The first subscript identifies the row and the second identifies the field number, as follows.
+//{{{
+vRecords(iRecord, iField)
+//}}}
+The following code example uses an SQL statement to retrieve three fields from a table into a //Recordset// object. It then uses the //~GetRows// method to retrieve the first three records of the //Recordset//, and it stores the selected records in a two-dimensional array. It then prints each record, one field at a time, by using the two array indexes to select specific fields and records.
+//{{{
+Sub ExtractDataTableBulk()
+Dim odbNorthwind As Object
+Dim orsOrders As Object
+Dim vRecords As Variant
+Dim iNumRows As Integer
+Dim iNumColumns As Integer
+Dim iRow As Integer
+Dim iColumn As Integer
+Dim sSQL As String
+
+On Local Error GoTo ErrorHandler
+
+ Set odbNorthwind = Application.CurrentDb
+ sSQL = "SELECT [OrderDate],[ShipAddress],[ShipCity] FROM Orders"
+ Set orsOrders = odbNorthwind.OpenRecordset(sSQL)
+
+ vRecords = orsOrders.GetRows(10)
+ iNumRows = UBound(vRecords, 1) + 1
+ iNumColumns = UBound(vRecords, 2) + 1
+
+ For iRow = 0 To inumRows - 1
+ For iColumn = 0 To iNumColumns - 1
+ DebugPrint vRecords(iRow, iColumn)
+ Next iColumn
+ Next iRow
+
+ orsOrders.mClose()
+ Set orsOrders = Nothing
+ Exit Sub
+
+ErrorHandler:
+ TraceError("ERROR", Err, "ExtractDataTableBulk", Erl)
+End Sub
+//}}}
+You can use subsequent calls to the //~GetRows// method if more records are available. Because the array is filled as soon as you call the GetRows method, you can see why this approach is much faster than copying one field at a time.
+
+Notice also that you do not have to declare the Variant as an array, because this is done automatically when the GetRows method returns records.
+
+If you are trying to retrieve all the rows by using multiple //~GetRows// calls, use the [[EOF|BOF, EOF]] property to be sure that you are at the end of the //Recordset//. The //~GetRows// method may return fewer rows than you request. If you request more than the remaining number of rows in a //Recordset//, the //~GetRows// method returns only the rows that remain.
+
+Because the //~GetRows// method always returns all the fields in the //Recordset// object, you may want to create a query that returns just the fields that you need. This is especially important for LONGVARBINARY and LONGVARCHAR (Memo) fields.

+
(Q) How do I find the current absolute and relative position in a recordset ?
+
+(R) The [[AbsolutePosition]] property returns the record number of the recordset. Associated with [[RecordCount]] the relative position can be derived.
+
+In some situations, you need to determine how far through a [[Recordset object|Recordset]] you have moved the current record position, and perhaps indicate the current record position to a user. For example, you may want to indicate the current position on a progress bar or similar type of control.
+
+The //~AbsolutePosition// property value is the position of the current record relative to 0. However, do not think of this property as a record number. There is no assurance that a record will have the same absolute position if the Recordset object is recreated because the order of individual records within a Recordset object is not guaranteed unless it is created with an SQL statement that includes an ORDER BY clause.
+
+We can compute the current relative position expressed as a percentage of the total number of records indicated by the //~RecordCount// property. Because the //~RecordCount// property does not reflect the total number of records in the //Recordset// object until the //Recordset// has been fully populated, we will use the [[MoveLast|Move (recordset)]] and [[MoveFirst|Move (recordset)]] methods immediately after opening the Recordset. This fully populates the //Recordset// object. If you have a large result set, using the //~MoveLast// method may take a long time.
+
+The following example opens a //Recordset// object on a table called Employees.
+<<tiddler "EmployeesTable">>
+The procedure then moves through the Employees table and uses the SysCmd method to display a progress bar showing the percentage of the table that has been processed.

+!!!Syntax
+//recordset//{{{.GetRows(}}}//numrows//{{{)}}}
+| !Argument | !Optional | !Type | !Description | !Returned value |
+|recordset || [[Recordset object|Recordset]] |An open recordset |//~GetRows// returns a two-dimensional array. The first subscript identifies the field and the second identifies the row number. |
+|numrows | N | Long |Specifies the maximum number of rows to retrieve. |~|
+!!!Remarks
+//~GetRows// returns a two-dimensional zero-based array.
+For example, to get the first field value in the second row returned, use code like the following:
+//{{{
+Dim vVarRecords() As Variant, oRecordset As Object, vField1 As Variant
+ Set oRecordset = ... OpenRecordset(...)
+ Set vVarRecords = oRecordset.GetRows(1000)
+ vField1 = vVarRecords(0, 1).
+//}}}
+To get the second field value in the first row, use code like the following:
+//{{{
+Dim vField2 As Variant
+ vField2 = vVarRecords(1, 0)
+//}}}
+The {{{vVarRecords}}} variable automatically becomes a two-dimensional array when //~GetRows// returns data. Otherwise //~GetRows// will return an uninitialized array (i.e. the output of the Basic builtin {{{Array()}}} function).
+Each element of the returned array will be of the Basic type most close to the [[DataType]] of the original database field.
+A {{{Null}}} field value in the database will be returned as a {{{Null}}} value in the array resulting from the invocation of //~GetRows//. To be evaluated with the {{{IsNull()}}} Basic builtin function.
+
+If you request more rows than are available, then //~GetRows// returns only the number of available rows. You can use the Basic {{{UBound}}} function to determine how many rows //~GetRows// actually retrieved, because the array is sized to fit the number of returned rows.
+For example, you could use the following code to determine how many rows were actually returned:
+//{{{
+ numReturned = UBound(vVarRecords, 2) + 1
+//}}}
+You need to use "+ 1" because the first row returned is in the 0th element of the array. The number of rows that you can retrieve is constrained by the amount of available memory. You shouldn't use //~GetRows// to retrieve an entire table into an array if it is large.
+Because GetRows returns all fields of the //Recordset// into the array, including Memo fields, you might want to use a query that restricts the fields returned.
+
+Binary fields are not returned. Instead the corresponding element in the array returned by //~GetRows// contains the //length// of the field.
+
+After you call //~GetRows//, the current record is positioned at the next unread row. That is, //~GetRows// has the same effect on the current record as {{{recordset.Move(numrows)}}}.
+If you are trying to retrieve all the rows by using multiple //~GetRows// calls, use the [[EOF|BOF, EOF]] property to be sure that you're at the end of the //Recordset//. //~GetRows// returns less than the number requested if it's at the end of the //Recordset//.
+
+Calling //~GetRows// cancels all not confirmed updates on the //recordset//.

+Read about ''[[BASEDOCUMENTER|http://www.access2base.com/basedocumenter]]'': a new ~LibreOffice __extension__ for producing a __HTML documentation__ of Base applications.
+~BaseDocumenter is based on the ~Access2Base library.
+!What is __~Access2Base__ ?
+
+{{firstletter{
+ @@color:#930;A@@
+ }}}''ccess2Base'' is a ~LibreOffice/~OpenOffice Basic library of macros for (business or personal) __application developers__ and __advanced users__.
+Their syntax and their meaning are directly inspired by //~MSAccess//. The macros are callable from
+*a ''~LibreOffice / ~OpenOffice Base'' application,
+*any ''~LibreOffice / ~OpenOffice document'' wanting to access data stored in databases.
+
+It is intended first to support people having a knowledge of ~MSAccess and willing to step over to a similar but free software, i.e. //~LibreOffice/~OpenOffice Base//.
+It is also useful for users having already a practical knowledge of ~LibreOffice/~OpenOffice (Base or other ...) and wanting to start building applications with it, while remaining focussed on the application or business logic only.
+
+//It is also recommended to people having tried to program in AOO/~LibO Basic with the standard ~LibreOffice/~OpenOffice UNO API and having given it up ...//
+
+The ''~Access2Base API'' is ''much more concise, intuitive, easy to learn'' and ''easy to use'' than the standard UNO API (API = Application Programming Interface).
+
+''
+~Access2Base is provided either
+>- __pre-installed as a standard feature in all versions of //~LibreOffice// since //~LibO version 4.2//__
+>- as an __extension__ downloadable from the //~LibreOffice// (versions <= 4.1) or //~OpenOffice// (all versions) download centers.
+The current and future versions of ~Access2Base (6.2.0) will be delivered only as a part of ~LibreOffice (>= 6.2).
+See the [[getting started instructions|Install]] for more details.
+''
+
+The implemented macros include:
+>1. a simplified and extensible ''__API__'' for [[forms|Forms]], [[dialogs|Dialog]] and [[controls|Controls]] manipulations similar with the ''//~MSAccess// object model''
+>2. an API for database access with the [[table|TableDef]], [[query|QueryDef]], [[recordset|Recordset]] and [[field|Field]] objects, aligned with the ''//DAO (Microsoft Data Access Object)// object model''
+>3. a number of actions with a syntax identical to their corresponding //~MSAccess// macros/actions including [[FindRecord]], [[RunCommand]], [[RunSQL]] or [[SelectObject]]
+>4. the DLookup, DSum, ... database functions
+>5. the support of the [[shortcut|ShortCut Notation]] notations like {{{Forms!myForm!myControl}}}
++
+>6. a consistent [[errors and exceptions handler|Error Handler]]
+>7. facilities for programming [[form, dialog and control events|Events Handler]]
+>8. the support of both //embedded forms// (in Base documents) and [[forms stored in non-Base documents|Standalone Forms]]

+''Call directly into TW core utility routines, define new functions, calculate values, add dynamically-generated ~TiddlyWiki-formatted output'' into tiddler content, or perform any other programmatic actions each time the tiddler is rendered.
+!!!!!Usage
+<<<
+This plugin adds wiki syntax for surrounding tiddler content with {{{<script>}}} and {{{</script>}}} markers, so that it can be recognized as embedded javascript code. When a tiddler is rendered, the plugin automatically invokes any embedded scripts, which can be used to construct and return dynamically-generated output that is inserted into the tiddler content.
+{{{
+<script type="..." src="..." label="..." title="..." key="..." show>
+ /* javascript code goes here... */
+</script>
+}}}
+All parameters are //optional//. When the ''show'' keyword is used, the plugin will also include the script source code in the output that it displays in the tiddler. This is helpful when creating examples for documentation purposes (such as used in this tiddler!)
+
+__''Deferred execution from an 'onClick' link''__
+<script label="click here" title="mouseover tooltip text" key="X" show>
+ /* javascript code goes here... */
+ alert('you clicked on the link!');
+</script>
+By including a {{{label="..."}}} parameter in the initial {{{<script>}}} marker, the plugin will create a link to an 'onclick' script that will only be executed when that specific link is clicked, rather than running the script each time the tiddler is rendered. You may also include a {{{title="..."}}} parameter to specify the 'tooltip' text that will appear whenever the mouse is moved over the onClick link text, and a {{{key="X"}}} parameter to specify an //access key// (which must be a //single// letter or numeric digit only).
+
+__''Loading scripts from external source files''__
+<script src="URL" show>
+ /* optional javascript code goes here... */
+</script>You can also load javascript directly from an external source URL, by including a src="..." parameter in the initial {{{<script>}}} marker (e.g., {{{<script src="demo.js"></script>}}}). This is particularly useful when incorporating third-party javascript libraries for use in custom extensions and plugins. The 'foreign' javascript code remains isolated in a separate file that can be easily replaced whenever an updated library file becomes available.
+
+In addition to loading the javascript from the external file, you can also use this feature to invoke javascript code contained within the {{{<script>...</script>}}} markers. This code is invoked //after// the external script file has been processed, and can make immediate use of the functions and/or global variables defined by the external script file.
+>Note: To ensure that your javascript functions are always available when needed, you should load the libraries from a tiddler that is rendered as soon as your ~TiddlyWiki document is opened, such as MainMenu. For example: put your {{{<script src="..."></script>}}} syntax into a separate 'library' tiddler (e.g., ~LoadScripts), and then add {{{<<tiddler LoadScripts>>}}} to MainMenu so that the library is loaded before any other tiddlers that rely upon the functions it defines.
+>
+>Normally, loading external javascript in this way does not produce any direct output, and should not have any impact on the appearance of your MainMenu. However, if your ~LoadScripts tiddler contains notes or other visible content, you can suppress this output by using 'inline CSS' in the MainMenu, like this: {{{@@display:none;<<tiddler LoadScripts>>@@}}}
+<<<
+!!!!!Creating dynamic tiddler content and accessing the ~TiddlyWiki DOM
+<<<
+An important difference between ~TiddlyWiki inline scripting and conventional embedded javascript techniques for web pages is the method used to produce output that is dynamically inserted into the document: in a typical web document, you use the {{{document.write()}}} (or {{{document.writeln()}}}) function to output text sequences (often containing HTML tags) that are then rendered when the entire document is first loaded into the browser window.
+
+However, in a ~TiddlyWiki document, tiddlers (and other DOM elements) are created, deleted, and rendered "on-the-fly", so writing directly to the global 'document' object does not produce the results you want (i.e., replacing the embedded script within the tiddler content), and instead will //completely replace the entire ~TiddlyWiki document in your browser window (which is clearly not a good thing!)//. In order to allow scripts to use {{{document.write()}}}, the plugin automatically converts and buffers all HTML output so it can be safely inserted into your tiddler content, immediately following the script.
+
+''Note that {{{document.write()}}} can only be used to output "pure HTML" syntax. To produce //wiki-formatted// output, your script should instead return a text value containing the desired wiki-syntax content'', which will then be automatically rendered immediately following the script. If returning a text value is not sufficient for your needs, the plugin also provides an automatically-defined variable, 'place', that gives the script code ''direct access to the //containing DOM element//'' into which the tiddler output is being rendered. You can use this variable to ''perform direct DOM manipulations'' that can, for example:
+* generate wiki-formatted output using {{{wikify("...content...",place)}}}
+* vary the script's actions based upon the DOM element in which it is embedded
+* access 'tiddler-relative' DOM information using {{{story.findContainingTiddler(place)}}}
+Note:
+''When using an 'onclick' script, the 'place' element actually refers to the onclick //link text// itself, instead of the containing DOM element.'' This permits you to directly reference or modify the link text to reflect any 'stateful' conditions that might set by the script. To refer to the containing DOM element from within an 'onclick' script, you can use "place.parentNode" instead.
+<<<
+!!!!!Instant "bookmarklets"
+<<<
+You can also use an 'onclick' link to define a "bookmarklet": a small piece of javascript that can be ''invoked directly from the browser without having to be defined within the current document.'' This allows you to create 'stand-alone' commands that can be applied to virtually ANY ~TiddlyWiki document... even remotely-hosted documents that have been written by others!! To create a bookmarklet, simply define an 'onclick' script and then grab the resulting link text and drag-and-drop it onto your browser's toolbar (or right-click and use the 'bookmark this link' command to add it to the browser's menu).
+
+Notes:
+*When writing scripts intended for use as bookmarklets, due to the ~URI-encoding required by the browser, ''you cannot not use ANY double-quotes (") within the bookmarklet script code.''
+*All comments embedded in the bookmarklet script must ''use the fully-delimited {{{/* ... */}}} comment syntax,'' rather than the shorter {{{//}}} comment syntax.
+*Most importantly, because bookmarklets are invoked directly from the browser interface and are not embedded within the ~TiddlyWiki document, there is NO containing 'place' DOM element surrounding the script. As a result, ''you cannot use a bookmarklet to generate dynamic output in your document,'' and using {{{document.write()}}} or returning wiki-syntax text or making reference to the 'place' DOM element will halt the script and report a "Reference Error" when that bookmarklet is invoked.
+Please see ~InstantBookmarklets for many examples of 'onclick' scripts that can also be used as bookmarklets.
+<<<
+!!!!!Special reserved function name
+<<<
+The plugin 'wraps' all inline javascript code inside a function, {{{_out()}}}, so that any return value you provide can be correctly handled by the plugin and inserted into the tiddler. To avoid unpredictable results (and possibly fatal execution errors), this function should never be redefined or called from ''within'' your script code.
+<<<
+!!!!!$(...) 'shorthand' function
+<<<
+As described by Dustin Diaz [[here|http://www.dustindiaz.com/top-ten-javascript/]], the plugin defines a 'shorthand' function that allows you to write:
+{{{
+$(id)
+}}}
+in place of the normal standard javascript syntax:
+{{{
+document.getElementById(id)
+}}}
+This function is provided merely as a convenience for javascript coders that may be familiar with this abbreviation, in order to allow them to save a few bytes when writing their own inline script code.
+<<<
+!!!!!Examples
+<<<
+simple dynamic output:
+><script show>
+ document.write("The current date/time is: "+(new Date())+"<br>");
+ return "link to current user: [["+config.options.txtUserName+"]]\n";
+</script>
+dynamic output using 'place' to get size information for current tiddler:
+><script show>
+ if (!window.story) window.story=window;
+ var title=story.findContainingTiddler(place).getAttribute("tiddler");
+ var size=store.getTiddlerText(title).length;
+ return title+" is using "+size+" bytes";
+</script>
+dynamic output from an 'onclick' script, using {{{document.write()}}} and/or {{{return "..."}}}
+><script label="click here" show>
+ document.write("<br>The current date/time is: "+(new Date())+"<br>");
+ return "link to current user: [["+config.options.txtUserName+"]]\n";
+</script>
+creating an 'onclick' button/link that accesses the link text AND the containing tiddler:
+><script label="click here" title="clicking this link will show an 'alert' box" key="H" show>
+ if (!window.story) window.story=window;
+ var txt=place.firstChild.data;
+ var tid=story.findContainingTiddler(place).getAttribute('tiddler');
+ alert('Hello World!\nlinktext='+txt+'\ntiddler='+tid);
+</script>
+dynamically setting onclick link text based on stateful information:
+>{{block{
+{{{
+<script label="click here">
+ /* toggle "txtSomething" value */
+ var on=(config.txtSomething=="ON");
+ place.innerHTML=on?"enable":"disable";
+ config.txtSomething=on?"OFF":"ON";
+ return "\nThe current value is: "+config.txtSomething;
+</script><script>
+ /* initialize onclick link text based on current "txtSomething" value */
+ var on=(config.txtSomething=="ON");
+ place.lastChild.previousSibling.innerHTML=on?"disable":"enable";
+</script>
+}}}
+<script label="click here">
+ /* toggle "txtSomething" value */
+ var on=(config.txtSomething=="ON");
+ place.innerHTML=on?"enable":"disable";
+ config.txtSomething=on?"OFF":"ON";
+ return "\nThe current value is: "+config.txtSomething;
+</script><script>
+ /* initialize onclick link text based on current "txtSomething" value */
+ var on=(config.txtSomething=="ON");
+ place.lastChild.innerHTML=on?"enable":"disable";
+</script>
+}}}
+loading a script from a source url:
+>http://www.TiddlyTools.com/demo.js contains:
+>>{{{function inlineJavascriptDemo() { alert('Hello from demo.js!!') } }}}
+>>{{{displayMessage('InlineJavascriptPlugin: demo.js has been loaded');}}}
+>note: When using this example on your local system, you will need to download the external script file from the above URL and install it into the same directory as your document.
+>
+><script src="demo.js" show>
+ return "inlineJavascriptDemo() function has been defined"
+</script>
+><script label="click to invoke inlineJavascriptDemo()" key="D" show>
+ inlineJavascriptDemo();

+2008.02.23 1.9.1 in onclick function, use string instead of array for 'bufferedHTML' (fixes IE errors)
+2008.02.21 1.9.0 output from 'onclick' scripts (return value or document.write() calls) are now buffered and rendered into into a span following the script. Also, added default 'return false' handling if no return value provided (prevents HREF from being triggered -- return TRUE to allow HREF to be processed). Thanks to Xavier Verges for suggestion and preliminary code.
+2008.02.14 1.8.1 added backward-compatibility for use of wikifyPlainText() in ~TW2.1.3 and earlier
+2008.01.08 [*.*.*] plugin size reduction: documentation moved to ...Info tiddler
+2007.12.28 1.8.0 added support for key="X" syntax to specify custom access key definitions
+2007.12.15 1.7.0 autogenerate URI encoded HREF on links for onclick scripts. Drag links to browser toolbar to create bookmarklets. IMPORTANT NOTE: place is NOT defined when scripts are used as bookmarklets. In addition, double-quotes will cause syntax errors. Thanks to ~PaulReiber for debugging and brainstorming.
+2007.11.26 1.6.2 when converting "document.write()" function calls in inline code, allow whitespace between "write" and "(" so that "document.write ( foobar )" is properly converted.
+2007.11.16 1.6.1 when rendering "onclick scripts", pass label text through wikifyPlainText() to parse any embedded wiki-syntax to enable use of HTML entities or even TW macros to generate dynamic label text.
+2007.02.19 1.6.0 added support for title="..." to specify mouseover tooltip when using an onclick (label="...") script
+2006.10.16 1.5.2 add newline before closing '}' in 'function out_' wrapper. Fixes error caused when last line of script is a comment.
+2006.06.01 1.5.1 when calling wikify() on script return value, pass hightlightRegExp and tiddler params so macros that rely on these values can render properly
+2006.04.19 1.5.0 added 'show' parameter to force display of javascript source code in tiddler output
+2006.01.05 1.4.0 added support 'onclick' scripts. When label="..." param is present, a button/link is created using the indicated label text, and the script is only executed when the button/link is clicked. 'place' value is set to match the clicked button/link element.
+2005.12.13 1.3.1 when catching eval error in IE, e.description contains the error text, instead of e.toString(). Fixed error reporting so IE shows the correct response text. Based on a suggestion by ~UdoBorkowski
+2005.11.09 1.3.0 for 'inline' scripts (i.e., not scripts loaded with src="..."), automatically replace calls to 'document.write()' with 'place.innerHTML+=' so script output is directed into tiddler content. Based on a suggestion by ~BradleyMeck
+2005.11.08 1.2.0 handle loading of javascript from an external URL via src="..." syntax

(Q) I can't put all the numerous fields of a table on one single form. I need several forms and will navigate thru them with buttons. Of course, when I navigate thru records, I want to keep all open forms synchronized with the active one. How can I get that ?
+
+(R) The synchronization will be obtained by using subforms and filters. However the challenge is to have one single concise code to do all the job.
+
+Let's consider next tables:
+<<tiddler "OrdersTable">>
+<<tiddler "OrderDetailsTable">>
+<<tiddler "CustomersTable">>
+<<tiddler "ProductsTable">>
+<<tiddler "EmployeesTable">>
+We will use 4 forms:
+*a //main// form and its subform for displaying Orders and their ~OrderDetails.
+*3 //auxiliary// forms for displaying on request more details about the concerned Customer, Product or Employee.
+*3 buttons (one for each of the 3 //auxiliary// forms) available from the //main// form activating the corresponding //auxiliary// form.
+The trick is that when navigating among orders or order details, the open //auxiliary// forms remain synchronized with the //main// form and its subform.
+!!!Synchronize all forms
+Link next code to next events:
+*//After record change// in the form events list
+*//Mouse button pressed// control events of each of the 3 buttons
+*//After record change// in the ''sub''form events list

(Q) When browsing thru a //recordset//, how can I identify that I reached the end ?
+
+(R) In a [[Recordset object|Recordset]], if you try to move beyond the beginning or ending record, an error occurs. For example, if you try to use the [[MoveNext|Move (recordset)]] method when you are already at the last record of the //Recordset//, an error occurs. For this reason, it is helpful to know the limits of the //Recordset// object.
+
+The [[BOF|BOF, EOF]] property indicates whether the current position is at the beginning of the //Recordset//. If //BOF// is {{{True}}}, the current position is before the first record in the //Recordset//. The //BOF// property is also {{{True}}} if there are no records in the //Recordset// when it is opened. Similarly, the [[EOF|BOF, EOF]] property is {{{True}}} if the current position is after the last record in the //Recordset//, or if there are no records.
+
+The following code example shows how to use the //BOF// and //EOF// properties to detect the beginning and end of a //Recordset// object. This code fragment creates a //Recordset// based on the ''Orders table'' from the current database. It moves through the records, first from the beginning of the //Recordset// to the end, and then from the end of the //Recordset// to the beginning.
+//{{{
+Dim odbNorthwind As Object
+Dim orsOrders As Object
+ Set odbNorthwind = Application.CurrentDb
+ Set orsOrders = odbNorthwind.OpenRecordset("Orders")
+
+ ' Do until ending of file.
+ Do Until orsOrders.EOF
+ ' Manipulate the data.
+ orsOrders.MoveNext ' Move to the next record.
+ Loop
+
+ orsOrders.MoveLast ' Move to the last record.
+ ' Do until beginning of file.
+ Do Until orsOrders.BOF
+ ' Manipulate the data.
+ orsOrders.MovePrevious ' Move to the previous record.
+ Loop
+
+ orsOrders.mClose()
+//}}}
+Be aware that there is no current record immediately following the first loop. The //BOF// and //EOF// properties both have the following characteristics.
+*If the //Recordset// contains no records when you open it, both //BOF// and //EOF// are {{{True}}}.
+*When //BOF// or //EOF// is {{{True}}}, the property remains {{{True}}} until you move to an existing record, at which time the value of //BOF// or //EOF// becomes {{{False}}}.
+*At the moment you create or open a //Recordset// that contains at least one record, the first record is the current record, and both //BOF// and //EOF// are {{{False}}}.
+*If the first record is the current record when you use the [[MovePrevious|Move (recordset)]] method, //BOF// is set to {{{True}}}. If you use //~MovePrevious// while //BOF// is {{{True}}}, an error occurs. When this happens, //BOF// remains {{{True}}} and there is no current record.
+*Similarly, moving past the last record in the //Recordset// changes the value of the //EOF// property to True. If you use the //~MoveNext// method while //EOF// is {{{True}}}, an error occurs.

(Q) Is it possible to mix calls to the //~Access2Base// API and to the //UNO// API in the same code ?
+
+(R) Yes, this is by the way exactly what //~Access2Base// does internally. Additionally most [[Access2Base objects|Object Model]] provide entries to useful //UNO// objects.
+
+!!!Documentation
+Next objects have within their properties one or more of them qualified as "UNO". Have a look at:
+*[[Database]]
+*[[Form]]
+*[[Control]] with the - very useful - //~ControlModel// and //~ControlView// properties

(Q) Can I move easily items from one listbox to another ?
+
+(R) Let's implement the classical method of moving either the selected items or all the items from one listbox to another and reciprocally.
+
+A first listbox is loaded from the database. The second one is empty.
+The goal is to load the second listbox with a selection of items from the first one, thanks to 4 buttons:
+*{{{>}}} and {{{<}}} move all selected items from one listbox to the other one and remove them from the original one.
+*{{{>>}}} and {{{<<}}} empty the original box and move all its items to the other one.
+!!!Solution
+It consists in putting on a form:
+*2 [[listboxes|ListBox]] called //~LeftList// and //~RightList//
+*4 buttons called //~MoveOneRight// ({{{>}}}), //~MoveAllRight// ({{{>>}}}), //~MoveOneLeft// ({{{<}}}), //~MoveAllLeft// ({{{<<}}})
+The code associated with the events is mainly a matter of arrays redimensioning, trimming and housekeeping. Both listboxes must be reinitialized from the event macro after each button activation to remain synchronized.
+
+Let's assume next table:
+<<tiddler "ProductsTable">>
+The //~LeftList// box is loaded initially with the //~ProductName// field of the //Products// table.
+
+1. Associate next code with the //When loading// form event: after initial loading the //~LeftList// control will be dissociated from its bound field. Additionally 3 constants are defined at module level.
+//{{{
+Const cstForm = "Products_FastSelect"
+Const cstLeftList = "LeftList"
+Const cstRightList = "RightList"

+Sub InitFirstList(poEvent As Object)

+ ocList.RowSource = sSource
+End Sub
+//}}}

+2. Associate the //Execute action// event of each of the 4 buttons with next macro:
+//{{{

(Q) I have a listbox control (might be MultiSelect) on my form. I want to pass the selected items to select the data listed in a gridcontrol on the same form. How do I do this?
+
+(R) The criteria must be built as a character string and passed to the [[RecordSource]] of the form.
+
+Assuming next tables:
+<<tiddler "SuppliersTable">>
+<<tiddler "ProductsTable">>
+and a form
+*bound to the Table "Products"
+*containing an unbound listbox having as data source
+//{{{
+ SELECT "CompanyName" FROM "Suppliers" ORDER BY "CompanyName" ASC
+//}}}
+!!!(1) Solution for ~MultiSelect = No listbox
+We make the //Changed// event of the listbox control triggering next code:
+//{{{
+Sub SyncFormListBoxMono(poEvent As Object)
+
+Dim oEvent As Object, ocList As Object, oForm As Object
+Dim sSupplier As String, lSupplier As Long
+
+ Set oEvent = Events(poEvent)
+ Set ocList = oEvent.Source ' Retrieve listbox object
+ Set oForm = ocList.Parent ' Retrieve parent form
+ sSupplier = Join(Split(ocList.Value, "'"), "''") ' For the case the company name contains quotes
+ lSupplier = DLookup("[SupplierID]", "[Suppliers]", "[CompanyName]='" & sSupplier & "'")
+ oForm.RecordSource = "SELECT [SupplierID], [ProductID], [ProductName], [UnitPrice] FROM [Products] WHERE [SupplierID]=" & lSupplier
+
+End Sub
+//}}}
+This will produce the requested effect.
+
+!!!(2) Solution for ~MultiSelect = Yes listbox
+A first variant is when the listbox is defined with ~MultiSelection = Yes
+//{{{
+Sub SyncFormListBoxMulti(poEvent As Object)
+
+Dim oEvent As Object, ocList As Object, oForm As Object
+Dim sSupplier As String, lSupplier As Long, i As Integer, sSQL As String
+Const cstCriteria = " OR [SupplierID]="
+
+ Set oEvent = Events(poEvent)
+ Set ocList = oEvent.Source ' Retrieve listbox object
+ Set oForm = ocList.Parent ' Retrieve parent form
+ sSQL = "SELECT [SupplierID], [ProductID], [ProductName], [UnitPrice] FROM [Products] WHERE [SupplierID]="
+ For i = 0 To UBound(oclist.Selected)
+ If ocList.Selected(i) Then
+ sSupplier = Join(Split(ocList.ItemData(i), "'"), "''") ' For the case the company name contains quotes
+ lSupplier = DLookup("[SupplierID]", "[Suppliers]", "[CompanyName]='" & sSupplier & "'")
+ sSQL = sSQL & lSupplier & cstCriteria
+ End If
+ Next i
+ oForm.RecordSource = Left(sSQL, Len(sSQL) - Len(cstCriteria)) ' Trim SQL phrase
+
+End Sub
+//}}}
+
+!!!(3) Solution with form filtering
+Another variant is to use a filter. This lets the user the freedom to cancel the filtering option or to filter the data independently from the listbox. This freedom can be desired by the developer or not. ~MultiSelection is presumed False in the example:
+//{{{
+Sub SyncFormListBoxFilter(poEvent As Object)
+
+Dim oEvent As Object, ocList As Object, oForm As Object
+Dim sSupplier As String, lSupplier As Long
+
+ Set oEvent = Events(poEvent)
+ Set ocList = oEvent.Source ' Retrieve listbox object
+ Set oForm = ocList.Parent ' Retrieve parent form
+ sSupplier = Join(Split(ocList.Value, "'"), "''") ' For the case the company name contains quotes
+ lSupplier = DLookup("[SupplierID]", "[Suppliers]", "[CompanyName]='" & sSupplier & "'")
+ oForm.Filter = "[SupplierID]=" & lSupplier
+ oForm.FilterOn = True

+The object class is returned for all objects as a string by the [[ObjectType]] property.
+!Remark about the //Application// and //~DoCmd// classes
+The //Application// and //~DoCmd// classes may be instantiated only once. Their instance MUST be called {{{Application}}} and {{{DoCmd}}} respectively. In fact they are implemented as module names.
+As an example, it is equivalent to write next statements:
+//{{{
+ DoCmd.OpenForm "anyform"
+//}}}
+or
+//{{{
+ OpenForm "anyform"
+//}}}
+This complies with the //~MSAccess// object model. Additionally this freedom solves potential homonymy issues between concurrent Basic libraries.
+!Collections - Functions returning objects
+Objects are created by the invocation of specific functions included in the API. In the calling procedure an object is defined as a variable of type //Object//.
+Example:
+//{{{
+Dim ofForm As Object ' Variant would also be correct
+ Set ofForm = AllForms("myForm") ' The Set verb is mandatory in MSAccess but optional in AOO/LibO Basic
+//}}}
+{{{ofForm}}} contains after execution the instance of an object of class Form.
+{{{AllForms}}} is called a [[collection|Collection]]. Individual members of a collection are reachable either by their index or by their name.
+!Properties
+!!!Property types
+Within an object class one can distinguish in the current documentation next 2 property types:
+| !Type of property | !Description |
+|UNO |The property refers to a UNO object that can be used from user macros to invoke directly alternative properties and methods to those supported by the //~Access2Base// API. |
+|Normal |Where it is really about in the //~Access2Base// software. Such a property complies with or is close to the //~MSAccess// object model. |
+!!!Property names
+The names of the properties are identical to their equivalent in //~MSAccess//.
+However
+*the semantics of the property might differ more or less,
+*their arguments might differ,
+*the returned values might be different.
+Read the documentation about each individual property for more info.
+!!!Get properties
+To get the value of a __normal__ property named "~MyProperty", write :
+{{indent{{{{vValue = myObject.MyProperty}}}
+Depending on the context an error message can be generated stopping the execution of the macro. The error message can be issued either by AOO/~LibO Basic or by the API.
+
+If the property is an array use :
+{{indent{{{{vValue = myObject.MyProperty(i)}}}
+!!!Set properties
+To set the value of a __normal__ property named "~MyProperty", use next syntax :
+{{indent{{{{myObject.MyProperty[(i)] = vValue}}}
+the optional argument being the index if the property returns an array.
+
+The macro will be stopped if the property setting failed.
+!!!Indirection
+To get the value of a __normal__ property of an object, one can write also:
+{{indent{{{{vValue = myObject.getProperty("MyProperty"[, i])}}}
+
+To set its value:
+{{indent{{{{myObject.setProperty("MyProperty", vValue[, i])}}}
+!!!Introspection
+Finally it is possible to get the value of ALL normal properties of an object with the //Properties// function as in next example:
+//{{{
+Dim ofForm As Object, i As Integer, oProperty As Object
+ Set ofForm = AllForms("myForm")
+ For i = 0 To ofForm.Properties().Count - 1
+ Set oProperty = ofForm.Properties(i)
+ Print oProperty.Name & " = " & oProperty.Value & " / ",
+ Next i
+ Print
+//}}}
+Additionally all objects have a {{{hasProperty}}} method indicating if the given property argument is applicable or not, like in:
+//{{{
+Dim ofForm As Object
+ Set ofForm = AllForms("myForm")
+ If ofForm.hasProperty("AllowEdits") Then
+ ...
+ End If
+//}}}
+!Methods
+!!!Method names
+The names of the methods are identical to their equivalent in //~MSAccess//.
+However
+*when the name is a ''reserved word'' in AOO/~LibO Basic the name is preceded by a "m" (like in method). E.g. //mClose// replaces //Close//,
+*the semantics of the method might differ more or less,
+*the arguments might be different in number or in admitted values or value types.
+Read the documentation about each individual method for more info.
+!!!Syntax
+Example:
+//{{{
+Dim ofForm As Object
+ Set ofForm = AllForms("myForm")
+ ofForm.Move(100, 200)
+//}}}
+!Compatibility
+Existing programs written with //~Access2Base// in versions older than 0.9.0 ''will not run normally''. The invocation of properties and methods like in
+>{{{getPROPERTY(OBJECT)}}}
+>{{{setPROPERTY(OBJECT, }}}//value//{{{)}}}
+>{{{METHOD(OBJECT, }}}//arg1, ...//{{{)}}
+''is not supported anymore as from ~Access2Base 1.7.0''.
+
+
+
+
The //~ObjectType// property specifies the type of an [[object|Object Model]].
+!!!Applies to ...

+
+
The //on ... control events// properties set or return the Basic script function which is executed when the event occurs.
+!!!Applies to ...
+The list below details which event is applicable on which control type. Additionally a distinction is made depending on the location of the control: within a [[form|Form]] (or [[subform|SubForm]]), a [[dialog|Dialog]] or a [[grid control|GridControl]].
+The last column indicates how the event is displayed in the properties box related to the control when the form or dialog is being edited.

+!!!Remarks
+*When applied to a table or a query data {{{DoCmd.OutputTo(...)}}} and {{{Application.CurrentDb().OutputTo(...)}}} are strictly equivalent.
+*The designated form MUST be open before the //~OutputTo// action is called.
+*If the {{{OutputFile}}} argument is not equal to space, and If the output file already exists, it will be overwritten without warning. If the user is prompted for the output file ({{{OutputFile}}} = space), the user will be requested to confirm the Save.
+*The {{{OutputFile}}} argument may be expressed either in the (recommended) URL format (i.e. "{{{file:// ...}}}") or by using the operating system usual syntax (e.g. "{{{C:\...}}}" in Windows).
+*Outputting a table or a query to a Calc, Excel or text file goes first through the generation of a Calc document which is saved via the adequate filter.
+*A text/csv file will always be encoded using the __Unicode (~UTF-8)__ character set. The choice of the field separator will depend on the locale setting for the decimal point: if it is a dot, then the field separator will be the comma, if it is a comma, then it will be the semi-colon. All text strings will be enclosed in double quotes.
+!!!Templating and styling
+Templates and CSS styles can be used when the output format is HTML and when the source of the exported data is a table or a query.
+The {{{TemplateFile}}} given as argument of the //~OutputTo// action may contain abreakny HTML tags, ~JavaScript code or any other element that is acceptable in a HTML page. ~Access2Base will leave them unchanged, except when a //token// is encountered. The only accepted tokens are
+| !Token | !Description |
+|{{{<!--Template_Title-->}}} |Will be replaced by the name of the table or the query. |
+|{{{<!--Template_Body-->}}} |Will be replaced by the effective data contained in the table or the query. |
+({{{<!--AccessTemplate_Title-->}}} and {{{<!--AccessTemplate_Body-->}}} are also accepted for compatibility with ~MSAccess)
+If the {{{TemplateFile}}} argument is absent, the default template used by ~Access2Base is:
+//{{{
+<!DOCTYPE html>
+<html>
+ <head>
+ <title><!--Template_Title--></title>
+ </head>
+ <body>
+ <!--Template_Body-->
+ </body>
+</html>
+//}}}
+To make CSS styling easy the data themselves will be generated together with next classes:
+| !Class | !Tags | !Typical usage |
+|{{{dbdatatable}}} | {{{<table>}}} |To not confuse the data table with other tables present in the template. |
+|{{{odd}}}<br />{{{even}}} | {{{<tr>}}} |To display alternate colors or backgrounds..|
+|{{{firstrow}}}<br />{{{lastrow}}} |~|To define specific borders above or under the first or the last row. |
+|{{{firstcol}}}<br />{{{lastcol}}} | {{{<th>}}}<br />{{{<td>}}} |To define specific borders on the left or the right of the first or the last column. |
+|{{{char}}}<br />{{{numeric}}}<br />{{{negative}}}<br />{{{date}}}<br />{{{bool}}}<br />{{{false}}}<br />{{{null}}} | {{{<td>}}} |To define display effects depending on the content of the table cell.<br />Like right justifying numbers, red fonts for negative numbers, special background for empty cells, etc. |

+!!!String encoding
+When exporting data from a table or a query, all strings will be "~UTF-8 encoded". See f.i. [[here|http://www.w3schools.com/charsets/ref_html_utf8.asp]] for more explanation.
+There are however a few exceptions. Some HTML tags (= NOT ALL) found within data strings will not be encoded. Typically links to pages located in <a> tags will remain unchanged.
+Next patterns will not be encoded:
+| !Pattern | !Remark |
+|{{{"}}}<br />{{{'}}} ||
+|{{{&}}} |"&" will be encoded as {{{&}}}. "{{{&}}}" will not be encoded as {{{&amp;}}} |
+|{{{<}}}<br />{{{>}}} ||
+|{{{ }}} |Multiple normal spaces will probably appear as one single space |
+|{{{<pre>}}}<br />{{{</pre>}}} |To preserve spacing and line breaks |
+|{{{<br>}}} |To force a line break |
+|{{{<a href="..."}}}<br />{{{<a id="..."}}}<br />{{{</a>}}} |References to hyperlinks or anchors may be present and will be preserved in strings |
+|{{{<img src="..."}}} |~|
+|{{{<span class="..."}}}<br />{{{</span>}}} |The <span> tag provides a way to add a specific class name or other hook to a part of a text or a part of a document |
+|{{{<b> </b>}}}<br />{{{<u> </u>}}}<br />{{{<i> </i>}}} |Usual editing tags |

Q: How can I output data to a web page and make it nice to read ?
+
+R: Data can be inserted statically in a web page thanks to the [[OutputTo]] action which will export the data to a static HTML page. The exported output shall contain predefined classes which can help producing nice effects. See the examples below.
+
+For all the examples we will use the //~EmployeesList// query.
+The query embeds html tags to allow browsing from the last column rapidly to the employee's manager.
+//{{{
+SELECT
+ '<a id="' || "Employees"."EmployeeID" || '">' || "Employees"."LastName" || '</a>' AS "Last name"
+ , "Employees"."FirstName" AS "First name"
+ , "Employees"."BirthDate" AS "Birth"
+ , "Employees"."Extension" AS "Phone"
+ , "Employees"."HomePhone" AS "Home phone"
+ , "Employees"."Title"
+ , '<a href="#' || "ReportingTo"."EmployeeID" || '">' || "ReportingTo"."LastName" || '</a>' AS "Manager"
+FROM
+ { OJ "Employees" AS "ReportingTo" RIGHT OUTER JOIN "Employees" ON "ReportingTo"."EmployeeID" = "Employees"."ReportsTo" }
+//}}}
+based on the //Employees// table:
+<<tiddler EmployeesTable>>
+The data will be generated by next statement:
+//{{{
+ DoCmd.OutputTo(acOutputQuery, "EmployeesList", acFormatHtml, sOutputFile, False, sTemplateFile, acUTF8Encoding)
+//}}}
+The template file contains nothing else but:
+//{{{
+<!DOCTYPE html>
+<html>
+ <head>
+ <title><!--Template_Title--></title>
+ <link rel="stylesheet" type="text/css" href="styleX.css">
+ </head>
+ <body>
+ <!--Template_Body-->

+!!!Remarks
+*//~RunCommand// always returns {{{True}}}. If the argument does not exist, or if the request is not appropriate to the context, the request is ignored.
+*The Command argument, when of type {{{String}}}, is not case-sensitive.
+*Above list of commands is not exhaustive. Other commands could succeed as well. However if the command to execute is not in the above list the argument MUST correspond exactly (... be properly cased as should ...) with the argument expected by a {{{executeDispatch()}}} UNO statement.
+*If the given Command argument is of type {{{String}}} and starts with "{{{.uno:}}}", the command is executed literally without any other parsing.
+*The ~LibO/AOO command and its VBA equivalent are //presumed// to be similar or equivalent. The ~RunCommand action always executes a ~LibO/AOO command. There is no emulation of the VBA command.
+*The //Context// column indicates one or more contexts in which the command has been tested and executed successfully. This is not a guarantee that it will succeed in the given context nor that other contexts could not also provide the same functionality. When the context is __//Any//__ this only means that the command is likely to succeed in any context.
+*The //~RunCommand// action is very often preceded by a [[SelectObject]] action to activate the correct context.
+*Most commands open a dialog box. Today the ~LibO/AOO documentation does not contain any indication about arguments that could bypass the dialog. The only ways to discover them are either to scan the software sources (what I did not do !) or to record the macro. But //~LibO/AOO Base// has no //Macro Recorder// (although Forms have ...!?) implemented.

(Q) Can I have a search box and trigger the search thru all the records related to a form ?
+
+(R) Use the [[FindRecord]] and [[FindNext]] actions.
+
+The feature is illustrated thru the use of a [[standalone form|Standalone Forms]].
+
+!!!Solution
+Design the //standalone// form taking into account:
+*The //~FindRecord// action works only on data displayed in a tabular form, i.e. through the use of a [[grid control|GridControl]].
+*You will observe that the execution is slow: indeed //~FindRecord// will literally scroll thru the data and refresh the display accordingly. The solution is not adapted for very large tables of data.
+
+Design next 4 fields and buttons:
+#The search box: a simple //text box//, name = //~SearchText//. In the //Properties// window set its //Default text// property to "(search)". Link its //When receiving focus// event to the //~CleanSearch// procedure.
+#A //checkbox// called //~MatchCase// indicating if the search must or not respect upper and lower cases.
+#A search start button : link the //execute action// event with the //~ButtonStart// procedure.
+#A //next// button : link the //execute action// event with the //~ButtonNext// procedure.
+
+Now the code:
+The //~CleanSearch// procedure empties the search box when its content is the default value:
+//{{{
+Const cstDefault = "(search)"
+
+Sub CleanSearch(poEvent As Object)
+Dim oEvent As Object, oField As Object
+ Set oEvent = Application.Events(poEvent)
+ Set oField = oEvent.Source
+ If oField.Value = cstDefault Then oField.Value = ""
+End Sub
+//}}}
+The //cstDefault// constant is set outside the //Sub...End Sub// to be available also in next procedures:
+//{{{
+Sub ButtonStart(poEvent As Object)
+Dim ofForm As Object, sSearch As String, bMatch As Boolean
+ Set ofForm = Application.Forms(0) ' standalone form itself

(Q) Can I make a search box where the proposed choices are dynamically limited to those starting with the letters typed by the user ?
+
+(R) There are several solutions. One of them is presented below.
+
+The implemented module is triggered each time a character is entered.
+Accepted characters are :
+*Letters, either lower or upper cased, and the space character
+*The BACKSPACE which cancels the last entered letter
+*The ESCAPE key which cancels the complete string of characters.
+Other keys are ignored.
+
+The goal is to minimize the reload of the data from the database, as it is an operation that could take a long time while the user is keying letters in ...
+
+!!!Solution
+It consists in:
+*A [[listbox|ListBox]]. It is reinitialized with database data at each //form loading//, and, while the focus is on the box, at each BACKSPACE key and at each ESCAPE key pressing.
+*After each letter pressed by the user the box keeps only the subset of the initial data that corresponds with the entered characters, without database access. The control is temporarily converted from an SQL [[RowSourceType]] to a VALUELIST one.
+*The succession of letters is kept into the [[Tag]] property of the //listbox//.
+Let's assume next table:
+<<tiddler "ProductsTable">>
+The //listbox// will help to converge as quickly as possible to the searched product name.
+
+1. Associate next code with the //When loading// form event:
+//{{{
+Sub InitList(Optional poEvent As Object) ' Optional because also called from CaptureChar routine
+'Activated when form opened and when ESC key is pressed in listbox
+
+Const cstForm = "Products_FastSearch"
+Const cstList = "FastList"
+Dim ocList As Object, sSource As String
+
+ Set ocList = Forms(cstForm).Controls(cstList)
+ If Not IsMissing(poEvent) Then ocList.Tag = "" ' Initialized only when form opened

+ ocList.RowSource = "SELECT [ProductName] FROM [Products] ORDER BY [ProductName] ASC" 'Requery implicit
+
+ sSource = Join(ocList.ItemData, ";")
+ ocList.RowSourceType = com.sun.star.form.ListSourceType.VALUELIST ' For performance
+ ocList.RowSource = sSource
+
+End Sub
+//}}}
+2. Associate next routine with the //Key pressed// event of the concerned //listbox// control :
+//{{{
+Sub CaptureChar(poEvent As Object)
+
+Dim oEvent As Object, ocList As Object, sTag As String, i As Integer
+Dim vList() As Variant, vNewList() As Variant, iNew As Integer

(Q) Can I easily simulate a tabbed interface (like in Calc ... ?) in a database form ?
+
+(R) A tabbed interface is for building wizards stepping from a page to the next or hiding/unhiding portions of a form when a button is clicked.
+This feature is builtin In a [[dialog|Dialog]]. See the [[Page]] property of dialogs and/or dialog [[controls|Control]].
+
+However in a form we will have to be more creative by:
+*making use of the concept of //sections// (remember that a database form is finally a Writer document ...). Indeed //sections// can be made programmatically hidden or visible very simply.
+*managing them by mixing the //~Access2Base// and //UNO// API's
+You have to understand that a //section// in a Writer document is nothing else than a set of __contiguous paragraphs__.
+If we anchor a control on the form to a paragraph, and if that paragraph is included a a //section//, when hiding the //section// the control will be made hidden as well.
+
+The concept has been derived from a topic from the (french) [[OpenOffice forum|https://forum.openoffice.org/fr/forum/viewtopic.php?f=29&t=23703]].
+
+In next example we have put the main form - except its 2 top buttons //Orders// and //Details// - , in the first section, and a subform in the second one.This allows us to obtain next result:
+
+[img[tabbed_orders.png]]
+and after having pressed the //Details// button:
+
+[img[tabbed_details.png]]
+!!!The code behind the top buttons
+//{{{
+Public Sub SelectTab(Optional poEvent As Object)
+Dim oEvent As Object, oForm As Object
+ Set oEvent = Application.Events(poEvent)
+ Set oForm = Forms("Orders_Tabbed")

+
+>''Each such form may access a separate database document !''

+To make such forms, documentation is available on several forums, e.g. [[here|http://user.services.openoffice.org/en/forum/viewtopic.php?t=40493]].

+|A //standalone form// ''CANNOT INTERACT'' with (either standalone or embedded) forms stored in ''OTHER DOCUMENTS''.<br />If it is necessary to exchange data between individual //~LibO/AOO// applications, use [[TempVar]] objects. Their scope is the whole //~LibO/AOO// session. |

+| !Function | !Limitation |
+|[[AllForms]] |The //~AllForms// collection is limited to the //standalone forms// stored in the same document.<br />When a document contains one single form - which is very often the case - the smart syntax for invoking that single form is simply:<br />{{{AllForms(0)}}}<br />which will return a //form object// representing the single //standalone form// itself, giving subsequently access to its individual controls. |
+|[[FindRecord]] |If the form contains subforms and if the targeted field to search on is in that subform, then the //~OnlyCurrentField// argument must be a {{{string}}} containing a [[shortcut|ShortCut Notation]] if the targeted grid or grid column is in the subform. |

+|[[Height]]<br />[[Width]]<br />[[Move]] |These methods, even when applied to a specific form, act on the containing window, i.e. on all its forms. |

(Q) How can I limit the contents of one combo/list box based on what's selected in another combo/list box ?
+
+(R) An easy way to do this would be to assign a dynamic SQL statement to the [[RowSource]] property of the secondary combo/list box at runtime.
+
+Our goal in the example is to select in a 1st combo box a CITY, in the 2nd combo the LASTNAME of the employees (working in CITY) to filter finally only the //Orders// placed by the concerned //Employee//.

+!!!Remarks
+*In //~MSAccess// the //~SysCmd// method is linked to the [[Application]] object.
+*The //~SysCmd// method will be often preceeded with a [[SelectObject]] action.
+*Only status bars of //forms// and //reports// can be managed with the //~SysCmd// method. When another window is active the method is ignored.
+*To display a progress meter in the status bar, you must first call the //~SysCmd// method with the ''acSysCmdInitMeter'' action argument, and the text and value arguments. When the action argument is ''acSysCmdInitMeter'', the value argument is the maximum value of the meter, or 100 percent.<br />To update the meter to show the progress of the operation, call the //~SysCmd// method with the ''acSysCmdUpdateMeter'' action argument and the text and value arguments. When the action argument is ''acSysCmdUpdateMeter'', the //~SysCmd// method uses the value argument to calculate the percentage displayed by the meter. For example, if you set the maximum value to 200 and then update the meter with a value of 100, the progress meter will be half-filled.
+*When a progress meter has been initiated with a ''acSysCmdInitMeter'' action argument, all subsequent calls to //~SysCmd// to feed the meter will be applied on the status bar of the same window even if other windows become active in the mean time.
+*You can also change the text that's displayed in the status bar of the currently active window by calling the //~SysCmd// method with the ''acSysCmdSetStatus'' action argument and the text argument.<br />If the progress meter is already displayed when you set the text by calling the //~SysCmd// method with the ''acSysCmdSetStatus'' action argument, the //~SysCmd// method automatically removes the meter, __even if the progress meter is on another - non active - window__.

+#optionally, edit TagsTreeStyleSheet.
+! Usage
+{{{<<tagsTree>>}}} macro accepts the following //optional// parameters.
+|!#|!parameter|!description|!by default|
+|1|{{{root}}}|Uses {{{root}}} tag as tree root|- In a //tiddler// content or template : uses the tiddler as root tag.<br>- In the //page// content or template (by ex MainMenu) : displays all untagged tags.|
+|2|{{{excludeTag}}}|Excludes all such tagged tiddlers from the tree|Uses default excludeLists tag|
+|3|{{{level}}}|Expands nodes until level {{{level}}}.<br>Value {{{0}}} hides expand/collapse buttons.|Nodes are collapsed on first level|
+|4|{{{depth}}}|Hierachy depth|6 levels depth (H1 to H6 header styles)|
+|5|{{{sortField}}}|Alternate sort field. By example : "index".|Sorts tags and tiddlers alphabetically (on their title)|
+|6|{{{labelField}}}|Alertnate label field. By example : "label".|Displays tiddler's title|
+
+!Useful addons
+*[[FieldsEditorPlugin]] : //create//, //edit//, //view// and //delete// commands in toolbar <<toolbar fields>>.
+*[[TaggerPlugin]] : Provides a drop down listing current tiddler tags, and allowing toggling of tags.

(Q) Some of the records in my database have values that are longer than the width of the bound control on the form. Is there a way I can display the complete text without requiring the user to click in the field and using arrow keys to read the value ?
+
+(R) Form controls have a property called [[ControlTipText]] (what you see in the yellow tooltip popup if you place the mouse over a control for some time). This property can be easily used to display the complete value of the actual control itself.
+!!!Solution
+Fire next code from the //After record change// event of a form:
+//{{{
+Sub setTipText(poEvent As Object)
+
+Dim ofForm As Object, ocControl As Object, i As Integer, sValue As String
+Const cstMin = 10
+Const cstMax = 200
+ Set ofForm = Events(poEvent).Source
+ For i = 0 To ofForm.Controls.Count - 1
+ Set ocControl = ofForm.Controls(i)
+ sValue = CStr(ocControl.Value)
+ If Len(sValue) > cstMin Then
+ If Len(sValue) > cstMax Then
+ ocControl.ControlTiptext = Left(sValue, cstMax)
+ Else
+ ocControl.ControlTiptext = sValue
+ End If
+ End If
+ Next i
+
+End Sub
+//}}}
+You will have noted that the tip text is modified only if long enough and truncated if the value is too long.

The //Type// property specifies the type of a [[query|QueryDef]], a [[commandbarcontrol|CommandBarControl]] or a [[Basic module|Module].
+!!!Applies to ...
+| !Object |!Description |
+|[[QueryDef]] |A stored query definition. |
+|[[CommandBarControl]] |An element of a [[CommandBar]]. |
+|[[Module]] |A Basic script. |
+!!!Syntax and returned values
+| !Syntax |!Returned value |>|
+|//querydef//{{{.pType}}} |dbQAction |A query that copies or changes data. Action queries include append, delete, make-table, and update queries. Delete and update queries change existing data; append and make-table queries copy existing data. In contrast, select queries return data records. An SQL pass-through query may also be an action query. |
+|~|dbQAppend |An action query that adds new records to the end of an existing table or query. Append queries don't return records (rows). |
+|~|dbQDDL |An SQL query that can create, alter, or delete a table, or create or delete an index in a database. |
+|~|dbQDelete |An action query that deletes a set of rows that match the criteria you specify. A delete query doesn’t return rows. |
+|~|dbQMakeTable |An action query that creates a new table from the Recordset object of an existing query. |
+|~|dbQSelect |A query that asks a question about the data stored in your tables and returns a Recordset object without changing the data. |
+|~|dbQSetOperation |An select query that creates a Recordset object containing data from all specified records in two or more tables with any duplicate records removed. To include the duplicates, add the keyword ALL. <br />For instance, a union query of the Customers table and the Suppliers table results in a Recordset that contains all suppliers that are also customers. |
+|~|dbQSQLPassThrough |An SQL query you use to send commands directly to the database (server). Pass-through queries are used to execute SQL queries and system-specific commands written by using SQL dialects known only to the server.<br />A pass-through query may or may not return records. |
+|~|dbQUpdate |An action query that changes a set of records according to criteria you specify. An update query doesn’t return any records. |
+|//commandbarcontrol//{{{.pType}}} |msoControlButton |The only supported value describing a command button. |
+|//module//{{{.pType}}} |acClassModule |The specified module is a class module. |
+|~|acStandardModule |The specified module is a susal, standard module. |
+!!!Remarks
+*The //Type// property is read-only.
+*The values returned by the //Type// property applied to a query may be combined. In fact they are summed. For instance an update query is also an action query. The property will return in such case the value dbQAction + dbQUpdate.<br />To test a single value, use next construction:

(Q) In code behind my form, I'm trying to reference the value contained in a control on my form in a SQL statement. But I'm not successful in doing this. I'm using the following syntax:
+--{{{sSQL = "SELECT * FROM Employees WHERE [LastName] = myControl.Value"}}}--
+What am I doing wrong??
+
+(R) In order to reference values contained in form controls, you have to use the & operator and concatenate the results. The positioning of quotes is also important.
+!!!Solution
+*In an SQL statement query-, table- and fieldnames are surrounded with a special character which is __depending on the used Relational Database Management System__. When used in character strings whose SQL nature is recognizable (in [[form filtering|Filter]], in a [[RunSQL]] action, a [[RecordSource]] or [[ControlSource]] property, ...), //~Access2Base// will substitute the square brackets ([ ... ]) with the correct character.<br />In next examples the resulting SQL statement is assumed to be used for such a purpose, reason why it still contains square brackets.
+*When the WHERE clause refers to a numeric field, it is sufficient to concatenate the SQL sentence and the value, like in:
+//{{{
+ sSQL = "SELECT * FROM Employees WHERE [Age] >= " & myNumericControl.Value
+//}}}
+*A bit more complicated is the reference to a date field. Simplest is to use the ISO representation of a date '''~YYYY-MM-DD''' (between single quotes):
+//{{{
+ Dim sDate As String
+ Const cstQuote = "'" ' Single quote
+ sDate = Format(myDateControl.Value), "YYYY-MM-DD")
+ sSQL = "SELECT * FROM Employees WHERE [BirthDate] = " & cstQuote & sDate & cstQuote
+//}}}
+*Similarly if the database field is of Date/Time type, the time should be added in the SQL statement. However the "time" control in the form is separated from the "date" one.
+//{{{
+ Dim sDateTime As String
+ Const cstQuote = "'" ' Single quote
+ sDateTime = Format(myDateControl.Value + myTimeControl.Value, "YYYY-MM-DD HH:MM:SS")
+ sSQL = "SELECT * FROM Employees WHERE [BirthDateTime] = " & cstQuote & sDateTime & cstQuote
+//}}}
+*Finally for simple strings, it seems easy. Just surround them with single quotes. However, if the string itself is able to contain a single quote, it is safer to anticipate its doubling:
+//{{{
+ Dim sName As String
+ Const cstQuote = "'" ' Single quote
+ sName = Join(Split(myCharControl.Value, cstQuote), cstQuote & cstQuote) ' Replace ' by ''
+ sSQL = "SELECT * FROM Employees WHERE [LastName] = " & cstQuote & sName & cstQuote
+//}}}
+

+!DEFINITIONS
+!!!What are objects ?
+AOO/~LibO Basic is a rudimentary object-oriented language.
+To stay close to the syntax of the //~MSAccess// object model the implementation of ~Access2Base has nevertheless been based on BASIC object classes. Their main characteristics are :
+**Use of classes of types ''Form'', ''Subform'' or ''Control'', etc.
+**In BASIC code using these classes, variables should be declared as being of type {{{Object}}}.
+**''Property'' and ''method'' names are identical in //~MSAccess// and in //~Access2Base//. Note however that //~Access2Base// implements only a limited subset of the object model of //~MSAccess//. Note also that their semantics might differ from the original //~MSAccess// one. Read the current documentation carefully.
+**Support of indirection and introspection for properties.
+**2 ROOT objects: [[Application]] and [[DoCmd]].
+**The [[CurrentDb]] method returns a [[Database]] object. It might be (and most often is ...) the database related to the only opened Base document (".odb") or any of the databases related to one of the [[standalone forms|Standalone Forms]] stored in a non-Base (Writer, Calc, ...) document.

+
+If you compare
