Call this function if your application supports Undo and the user chooses Undo after activating an item but before editing it.
BOOL DeactivateAndUndo( );
Возвращаемое значение
Nonzero on success; otherwise 0.
Заметки
If the container application is written using the Microsoft Foundation Class Library, calling this function causes COleClientItem::OnDeactivateAndUndo to be called, which deactivates the server's user interface.
