Hi all

I have a program written in VC6 (running on XP) that I want to stop from having multiple copies open. I want it to check whether there is another instance of itself running on start up and close if there is. Using FindWindow() doesnt work as it finds itself!

Thanks for any help

Solution 1

You can try creating a named mutex with CreateMutex() API and checking the result with GetLastError(). When the second instance of the app tries to create it, GetLastError() will return ERROR_ALREADY_EXISTS as the mutex is already created by the first instance.
