Hello, I ask to forum an other question in order to implement a new function to my program named START.AU3

Someone can suggest me how start only one istance of my program??

When I compile STARTau3 to EXE and I run it i want that it run only on the first mouse click on exe file.

If I click an other time it must do nothing beacuse it is already in memory.

I have thinked to command "IF PROCESSEXIST ...-START.exe-" but the problem is that the process always exist

when I run it.

If I think NOT exist is always false beacuse when I run it automatically exist in memory.

I have think PID but nothing to do.

The only way that permit me that is create a file START-RUN.txt and test if the file exist or not....

and delete file when I close program

..but there is a bug....

if computer shutdown when START is running (breaking tension voltage or other problems) the file always exist

but START is NOT running.

Someone have suggestion??

Thanks
