Declare statement Declare Statement DLL (Dynamic Link Library) Declares and defines a subroutine in a DLL file that you want to execute from $[officename] Basic.

See also: FreeLibrary Syntax: Declare {Sub | Function} Name Lib "Libname" [Alias "Aliasname"] [Parameter] [As Type] Parameters: Name: A different name than defined in the DLL, to call the subroutine from $[officename] Basic. Aliasname: Name of the subroutine as defined in the DLL. Libname: File or system name of the DLL. This library is automatically loaded the first time the function is used. Argumentlist: List of parameters representing arguments that are passed to the procedure when it is called. The type and number of parameters is dependent on the executed procedure. Type: Defines the data type of the value that is returned by a function procedure. You can exclude this parameter if a type-declaration character is entered after the name. To pass a parameter to a subroutine as a value instead of as a reference, the parameter must be indicated by the keyword ByVal. Example: Declare Sub MyMessageBeep Lib "user32.dll" Alias "MessageBeep" ( Long ) Sub ExampleDeclare Dim lValue As Long lValue = 5000 MyMessageBeep( lValue ) FreeLibrary("user32.dll" ) End Sub
