How to uniquely identify a process?

[nano2k]

Hi
I have an application (let's call it Main.exe) and a helper process
(call it Update.exe) that periodically updates Main app.
Update.exe needs to reside in memory, but I need to make sure that
EXACTLY ONE process is running.
Anyway, other "Update.exe" processes may run simultaneously at one
time, so I need to check the right one.
What's the most reliable method?

Thanks.

Hello nano2k,

Use Global Mutex in your update.exe http://msdn2.microsoft.com/en-us/library/system.threading.mutex.aspx
