Remarks
Notes to Callers
The in-place object calls IOleInPlaceSite::OnUIActivate just before activating its user interface.Notes to Implementers
The container should remove any user interface associated with its own activation. If the container is itself an embedded object, it should remove its document-level user interface.If there is already an object active in place in the same document, the container should call IOleInPlaceObject::UIDeactivate before calling OnUIDeactivate.
