Can anyone tell me what (obvious to everyone else) piece I'm missing.
The following code doesn't work when run as a service. It runs fine
when run through the IDE.  All it does is set a timer.  The SetTimer returns
a valid number, but the TimerProc callback is never hit.

Any ideas?

            _AtlModule.LogEvent(_T("TimerEvent"));
        }
