IOleObject::Unadvise

Comments
Normally, containers call IOleObject::Unadvise at shutdown or when an object is deleted. In certain cases, containers can call this method on objects that are running but not currently visible as a way of reducing the overhead of maintaining multiple advisory connections. The easiest way to implement this method is to delegate the call to IOleAdviseHolder::Unadvise.
