Syntax

);
Parameters

| Return code | Description |
|---|---|
|
An unexpected error has occurred. |
Remarks
The object indicates whether it can undo changes through the fUndoable flag. If the object can undo changes, the container can (by the user invoking the Edit Undo command) call the IOleInPlaceObject::ReactivateAndUndo method to undo the changes.
Notes to Callers
IOleInPlaceSite::OnUIDeactivate is called by the site's immediate child object when it is deactivating to notify the container that it should reinstall its own user interface components and take focus. The container should wait for the call to IOleInPlaceSite::OnUIDeactivate to complete before fully cleaning up and destroying any composite submenus.Requirements
