Closing Existing Instance

[stathread]

I built an application which runs in the system tray. If I forget its running and click the exe it opens another instance. Is there a way to check to see if there is already one running on the local machine?

Thanks

Another technique which is even easier is to attempt to create a named Mutex:

bool wasCreated;
Mutex myMutex = new Mutex(false, "some long and difficult to copy name", out wasCreated);
if (wasCreated)
{
   // Run app normally
}
