Deactivates an active in-place object and discards the object's undo state.

HRESULT InPlaceDeactivate();

Return Values


The object was successfully deactivated.


An unexpected error occurred.


Notes to Callers

This method is called by an active object's immediate container to deactivate the active object and discard its undo state.

Notes to Implementors

On return from IOleInPlaceObject::InPlaceDeactivate, the object discards its undo state. The object application should not shut down immediately after this call. Instead, it should wait for an explicit call to IOleObject::Close or for the object's reference count to reach zero.

Before deactivating, the object application should give the container a chance to put its user interface back on the frame window by calling IOleInPlaceSite::OnUIDeactivate.

If the in-place user interface is still visible during the call to InPlaceDeactivate, the object application should call its own IOleInPlaceObject::UIDeactivate method to hide the user interface. The in-place user interface can be optionally destroyed during calls to IOleInPlaceObject::UIDeactivate and IOleInPlaceObject::InPlaceDeactivate. But if the user interface has not already been destroyed when the container calls IOleObject::Close, then it must be destroyed during the call to IOleObject::Close.

During the call to IOleObject::Close, the object should check to see whether it is still active in place. If so, it should call InPlaceDeactivate.
