How do I find out what is causing an exception?

[cathym]

I wrote a com in vc++ to execute an excel spreadsheet every minute. This spreadsheet also uses an add-in that is a DDE link. It works well, except that intermittently I get an excel unknown exception, and excel terminates. This happens ever 1 to 2 hours.

Does anyone know how I can find out what is causing this exception so I can fix it?

Try to put OutputDebugStrings on the line...and use DebugViewer software to view those outputs, which u can get from sysinternals.com.
And about excel exception..i think u r not releasing any resources from excel...that may be causing exception at excel end.
Please read about the calls in excel automation carefully, and verify all the requirements.
