How to trap events exposed by Office applications

You can trap events that are exposed by Microsoft Office applications by implementing the event interface you want to catch (the "sink"), and setting up an advisory connection with the application (the "source").

To set up the advisory connection, you get the server's IConnectionPointContainer and call FindConnectionPoint() with the IID of the event interface. This gives you an IConnectionPoint interface. Then call Advise() with an instance of your event interface. The server will call back through this interface when these events occur.
