>>Nice catch, Larry. In fact, I just finished testing this and, unfortunately, like creating a mutex, you have to clear the Event, apparently using ResetEvent() followed by a close. Serves me right for opening my mouth before reading the SDK.< g >

>Issuing a CloseHandle() with no other process holding an event handle makes the event object disappear, regardless of the state. If you forget to CloseHandle, issuing a CLOSE ALL, or QUITting VFP releases the handle and makes the event go away. I'm actually leveraging the CreateEvent() behavior rather than the Event itself; the existance of the Event serves as an indication that someone else already is running, and is still running.

>Try it. There's no causal link between PROGRAM(0) - it's just a name that's easily codified; presumably any instance of the program you're running will have the same PROGRAM(0), so even if you cancel out, a CLOSE ALL or calling CloseHandle() avoids the need to exit VFP. RTFMSDN

OK, OK, I did, I did. What penance do you need me to do?< cower, cower >
