IAdviseSink::OnClose
Called by the
server to notify all registered advisory sinks that the object has changed from
the running to the loaded state.
Void
OnClose();
Remarks
OnClose notification indicates that an object is making the
transition from the running to the loaded state, so its container can take
appropriate measures to ensure orderly shutdown. For example, an object handler
must release its pointer to the object.
If the object
that is closing is the last open object supported by its OLE server
application, the application can also shut down.
In the case
of a link object, the notification that the object is closing should always be
interpreted to mean that the connection to the link source has broken.
