Check if an instance of my program is already running?

Recommended Posts


I know i read this somewhere in the help file so i know its possible (i think) but i can't find it again. But im pretty sure there is a way to have your program check if there is 2+ instances of it running. How can i accomplish this?

I already tried:

If ProcessExists("myProgram.exe") Then MsgBox(0, "", "Process already exists")

But that won't work i tried with just 1 instance of it and it still detects itself even though there is 1 instance.
