CWnd::EnableActiveAccessibility
Enables user-defined Active Accessibility functions.
void EnableActiveAccessibility( );
Remarks
MFC's default Active Accessibility support is sufficient for standard windows and controls, including ActiveX controls; however, if your CWnd-derived class contains nonwindowed user interface elements, MFC has no way of knowing about them. In that case, you must override the appropriate Active Accessibility member functions in your class, and you must call EnableActiveAccessibility in the class's constructor.
