In the case of IAccessible2::relations + and IAccessibleRelation::targets the client must allocate and free the arrays. + + For the remaining methods which return arrays, the server must allocate the array + and the client must free the array when no longer needed. These methods are + IAccessible2::extendedStates, IAccessible2::localizedExtendedStates, + IAccessible2_2::relationTargetsOfType, IAccessibleAction::keyBinding, + IAccessibleHypertext2::hyperlinks, IAccessibleTable::selectedChildren, + IAccessibleTable::selectedColumns, IAccessibleTable::selectedRows, + IAccessibleTable2::selectedCells, IAccessibleTable2::selectedColumns, + IAccessibleTable2::selectedRows, IAccessibleTableCell::columnHeaderCells, + and IAccessibleTableCell::rowHeaderCells. + For those methods, the server must allocate both the top level array and any storage + associated with it, e.g. for BSTRs. The server must allocate the arrays with + CoTaskMemAlloc and any BSTRs with SysAllocString. The client must use CoTaskMemFree + to free the array and any BSTRs must be freed with SysFreeString. + + Also, the IDL for IAccessible2::extendedStates, IAccessible2::localizedExtendedStates, + IAccessibleAction::keyBinding, IAccessibleTable::selectedChildren, + IAccessibleTable::selectedColumns, and IAccessibleTable::selectedRows includes an + extraneous [in] parameter for the caller to specify the max size of the array. + This parameter will be ignored by the COM server. + + @section _indexes Zero and One Based Indexes + Unless otherwise specified all offsets and indexes are 0 based. + + @section _enumBase Enum Base + Note that enums start at 0. + + @section _specialOffsets Special Offsets for use in the IAccessibleText and IAccessibleEditableText Methods + IAccessibleText and IAccessibleEditableText can use one or more of the following + special offset values. They are defined in the ::IA2TextSpecialOffsets enum. + @li Using ::IA2_TEXT_OFFSET_LENGTH (-1) as an offset in any of the IAccessibleText or + IAccessibleEditableText methods is the same as specifying the length of the string. + @li Using ::IA2_TEXT_OFFSET_CARET (-2) as an offset for IAccessibleText::textBeforeOffset, + IAccessibleText::textAtOffset, and IAccessibleText::textAfterOffset indicates that the + text related to the physical location of the caret should be used. This is needed for + applications that consider the character offset of the end of one line (as reached by + pressing the End key) the same as the offset of the first character on the next line. + Since the same offset is associated with two different lines a special means is needed + to fetch text from the line where the caret is physically located. + + @section _dicoveringInterfaces Discovery of Interfaces + In general AT (Assistive Technology) should try IAccessible2 interfaces, followed by using + the MSAA (Microsoft® Active Accessibility®) interfaces. (In cases where the an application + is known to have custom interfaces which provide information not supplied by IAccessible2 + or MSAA, then those custom interfaces can be used.) The AT can then, by default, support + unknown IAccessible2/MSAA applications, without the application developers having to request + AT vendors for support on an individual application by application basis. + + When you have a reference to an IAccessible and require a reference to an IAccessible2 use + QueryService as follows: + @code + // pAcc is a reference to the accessible object's IAccessible interface. + IServiceProvider *pService = NULL; + hr = pAcc->QueryInterface(IID_IServiceProvider, (void **)&pService); + if(SUCCEEDED(hr)) { + IAccessible2 *pIA2 = NULL; + hr = pService->QueryService(IID_IAccessible, IID_IAccessible2, (void**)&pIA2); + if (SUCCEEDED(hr) && pIA2) { + // The control supports IAccessible2. + // pIA2 is the reference to the accessible object's IAccessible2 interface. + } + } + @endcode + + @section _changingInterfaces Changing between Accessible Interfaces + Note that developers must always implement MSAA's IAccessible and, if needed, some + of the interfaces in the set of IAccessible2 interfaces. Although the IAccessible2 + IDL is coded such that IAccessible2 is a subclass of MSAA's IAccessible, none of + MSAA's IAccessible methods are redefined by IAccessible2. + + QueryService must be used to switch from a reference to an MSAA IAccessible interface + to another interface. This has been + <a href="http://www.atia.org/files/public/Introducing_IAccessibleEx.doc"> + documented</a> and the pertinent facts have been extracted below: + + @par + Why use QueryService instead of just using QueryInterface to get IAccessibleEx + directly? The reason is that since MSAA 2.0, clients don't talk to a server's + IAccessible interface directly; instead they talk to an intermediate MSAA-provided + wrapper that calls through to the original IAccessible. This wrapper provides services + such as implementing IDispatch, supplying information from MSAA 2.0's Dynamic Annotation + service, and scaling locations when running on Windows Vista with DPI scaling enabled. + QueryService is the supported way to expose additional interfaces from an existing + IAccessible and was originally used by MSHTML to expose IHTMLElement objects corresponding + to IAccessibles. QueryService is often more convenient for servers to implement than + QueryInterface because it does not have the same requirements for preserving object + identity or symmetry/transitivity as QueryInterface, so QueryService allows servers to + easily implement the interface on the same object or a separate object. The latter is + often hard to do with QueryInterface unless the original object supports aggregation. + + Two related references in MSDN® are: + @li <a href="http://msdn.microsoft.com/en-us/library/ms696078(VS.85).aspx"> + "Using QueryService to expose a native object model interface for an IAccessible object"</a> + @li <a href="http://msdn.microsoft.com/en-us/library/ms528415.aspx#acc_obj"> + "Accessing the Internet Explorer Object Associated with an Accessible Object"</a> + + Based on this information from Microsoft, QueryService must be used to switch back and forth + between a reference to an MSAA IAccessible interface and any of the IAccessible2 interfaces. + + Regarding switching between any of the IAccessible2 interfaces, applications implementing + IAccessible2 should implement the IAccessible2 interfaces on a single object since ATs + will be using QueryInterface to switch between the IAccessible2 interfaces. Implementing + the IAccessible2 interfaces on separate objects would require the use of QueryService. + There is one exception, IAccessibleApplication can be implemented on a separate object so + its common code doesn't have to be included in each accessible object. ATs should use + QueryService to access IAccessibleApplication. + + @section _applicationInfo Access to Information about the Application + Servers implementing IAccessible2 should provide access to the IAccessibleApplication + interface via QueryService from any object so that ATs can easily determine specific + information about the application such as its name or version. + + @section _childIDs Child IDs + The IAccessible2 interfaces do not support child IDs, i.e. simple child elements. + Full accessible objects must be created for each object that supports IAccessible2. + Therefore MSAA's get_accChild should never return a child ID (other than CHILDID_SELF) + for an object that implements any of the IAccessible2 interfaces. + + Microsoft's UI Automation specification has the same limitation and this was resolved + in the UI Automation Express specification by adding IAccessibleEx::GetObjectForChild + and IAccessibleEx::GetIAccessiblePair. These methods allow mapping back and forth + between an IAccessibleEx and an {IAccessible, Child ID} pair. A future version of + IAccessible2 may include similar methods to map back and forth between an IAccessible2 + and an {IAccessible, Child ID} pair. + + @section _variants VARIANTs + Some methods return a VARIANT. Implementers need to make sure that the return type is + specified, i.e. VT_I4, VT_IDISPATCH, etc. The methods that return VARIANTs are + IAccessibleHyperlink::anchor, IAccessibleHyperlink::anchorTarget, IAccessibleValue::currentValue, + IAccessibleValue::maximumValue, IAccessibleValue::minimumValue. + + @section _iaaction-iahyperlink IAccessibleHyperlink as subclass of IAccessibleAction + In this version of the IDL, IAccessibleHyperlink is a subclass of IAccessibleAction. + However, there is no practical need for that inheritance and in some cases, such as + an image map of smart tags, it doesn't make sense because such an image map doesn't + have actionable objects; it's the secondary smart tags that are actionable.

This interface is derived + from IAccessibleAction.

This interface could + also be applied to other kinds of objects with multiple actions such as "smart tags" + which are objects, typically strings, which have multiple actions such as + "Activate URI", "Bookmark URI", etc. + + An interesting use case is an image map where each area is associated with multiple + actions, e.g. an image map of smart tags. In this case you would have to implement + two levels of accessible hyperlinks. The first level hyperlinks would only implement + anchor and anchorTarget. The anchors would all reference the image object. The + anchorTargets would reference the second level accessible hyperlink objects. None + of the IAccessibleAction methods would be implemented on the first level hyperlink + objects. The second level hyperlink objects would implement the IAccessibleAction + methods. Their anchors would also reference the image object and their anchorTargets + would reference URLs or the objects that would be activated. + + This use case demonstrates that in some cases there is no need for IAccessibleHyperlink + to derive from IAccessibleAction.
