i want check if process is run and not working

This is my code and it says running , In the event that process is not running

What I have tried:

Process[] proc = Process.GetProcessesByName("Processname");
                     if (proc.Length > 1)
                     {
                         MessageBox.Show(" Process is Run", "form1", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                         Application.Exit();

                     }
                     else
                     {
                         Application.EnableVisualStyles();
                         //   Application.SetCompatibleTextRenderingDefault(true);
                         Application.Run(new Form3());

                     }

I think you're looking for how to use a Mutex to detect whether or not the application is already running.

You're going to have to come up with more detail that this.

If a process shows up in the list returned by GetProcessesByName, it was definitely launched and is running.

Are you passing in the correct "Processname"? That's going to be the name on the Details tab of Task Manager, like "notepad.exe", or just "notepad".

Are you talking about if you click in the window of an application and it comes back with "Not Responding"?

OK, so your code found 4 instances of whatever process you're looing for. So what if there's just once instance, or none?
