Will you please tell me what library " Process.Start() method" requires? (E.G. Using System.???) I would like to do something very similar to what you did. I copied the code that Robin furnished and the compiler complained that the "Process pcs =new Process();" had no assembly directive.(???) The best I can figure is that I did not use the correct library. There may be an easy way to do this, but I am not a software guy. Any help would be appreciated.

I'm very sorry - forgot to add this line: pcs.EnableRaisingEvents = true; befor pcs.Start(); With that, exited event will be raised.

Hi Robin, thanks a lot, that's what i wanted, but I am experiencing a problem. My test code after your suggestion: private void someMethod(){ Process pcs=new Process(); pcs.Exited+=new EventHandler(pcs_Exited); pcs.StartInfo.FileName="notepad.exe"; pcs.Start(); } private void pcs_Exited(object sender, EventArgs e) { MessageBox.Show("process exited"); } My problem is that notepad starts, but when I close it, the pcs_Exited is not called. (I don't see any message box) What am I doing wrong? thnx again, geo

in the function where you start process... Process pcs = new Process(); pcs.Exited += new EventHandler(CurrentForm_ProcessExited); ....... pcs.Start(); } and handler: private void CurrentForm_ProcessExited(object sender, EventArgs e) { //do something MessageBox.Show(this, "You child process has just run away!!!"); }
