Vlad,
Ok, back to basics.
I thought that when you compiled the COM application into a DLL it automatically runs.
Am I wrong?
If so, how to you create the COM object? I tried:
goApp=CREATEOBJECT("ImpactCOM")
It didn't work
TIA

Probably you can do that using API functions, but better to maintain some sort of flag in each function of the COM object. If flag is set, the object is running. Stroer also the time when flag is created to avoid situation with power off or crashes.
