Waiting for a Process to end without freezing the starting app

[Dan Neely]

Process.WaitForExit() is a blocking call. Is there a nonblocking equivilant, or will I need to call the 2nd app from a thread. I need to know when it's finished so that I can clean up the temp files I created for it as input.

You can handle Process.Exited event. like this: Process notepadProcess; private void button1_Click(object sender, EventArgs e) { notepadProcess = new Process(); notepadProcess.EnableRaisingEvents = true; // tell process to raise Exited event notepadProcess.Exited += new EventHandler(notepadProcess_Exited); // Exited event handler notepadProcess.StartInfo.FileName = "notepad.exe"; notepadProcess.Start(); } void notepadProcess_Exited(object sender, EventArgs e) { MessageBox.Show("Notepad process just has been exited."); notepadProcess.Dispose(); } Robin Panther http://www.robinland.com

Thanks. I figured there had to be a more graceful way to do it.
