Remarks
IOleAdviseHolder::Unadvise is intended to be used to implement IOleObject::Unadvise to delete an advisory connection. In general, you would use the OLE advise holder having obtained a pointer through a call to CreateOleAdviseHolder.
Usually, containers call this method at shutdown or when an object is deleted. In certain cases, containers could call this method on objects that are running but not currently visible, as a way of reducing the overhead of maintaining multiple advisory connections.
