SYS(2800 [,nFlag] )

Parameters

nFlag

Disables accessibility support or enables various accessibility functionality according to the following table.

Note
The flags are additive.

nFlags	Description
0	Disables Active Accessibility (AA).
1	Enables WM_GETOBJECT.
2	Enables NotifyWinEvent.
4	Causes Visual FoxPro to not return to Accessibility clients until a specified action is complete. Overrides the messages of certain methods of IAccessible, such as accDoDefaultAction or accSelect, to process the client's request and return to the client immediately.
16	Enables ACCNAME. Returns object Name rather than Caption. Use for testing.
32	For backward compatibility only.

The default for nFlag is 3, which is the sum of "Enables WM_GETOBJECT" (2) + "Enables NotifyWinEvent" (3).

For details on WM_GETOBJECT, NotifyWinEvent, and accDoDefaultAction, see the Accessibility topic in the User Interface Services section of Platform SDK in the MSDN Online Library.
