Hi,

We are developing a .NET assembly(EXE). We wanted to make
sure that only one instance of EXE running. Is there any
way to verify(using framework classes) other instance
same exe is running or not? If it is then we can exit.

Hope I am clear.

Thanks
Nagaraju

Sure, you can use a System.Threading.Mutex to achieve this.

tex+single+instance

2nd result has some code, as do many of the other results.

HI Nagaraj,

U can use system.diagnstics name space and find the all
process running on the machine.
if you find your Process name in the Process Collection
you can prompt a MSG and exit the Application

That doesn't always work. What if the user renames the executable?
