How to prevent multiple instances of program executable?

[DanP]

I have a relatively large program built using LabWindows/CVI.

Is there any way to prevent a user from opening multiple instances of the executable? So, if a user already has the program open, clicking its icon on the start menu or desktop would either do nothing or bring the currently running program into focus instead of opening a separate instance?

Thanks.

Just look at the CVI examples. There is one showing how to do it. Or
check out CheckForDuplicateAppInstance function help.

Thanks so much, I guess I should have figured that out on my own.
