Only one Istance
Posted 23 March 2012 - 11:12 AM
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??
