          static void Main(string[] args)
         {
                 Console.WriteLine("Press Enter to start Notepad (i.e. Process 1)");

                 Console.ReadKey();
                 Console.WriteLine("Starting Notepad...");
                 Thread t1 = new Thread(new ThreadStart(StartProcess1));
                  t1.Start();

                  while (t1.IsAlive == true)
                 {
                      System.Threading.Thread.Sleep(1000);
                 }

                 Console.WriteLine("Notepad Stopped. Starting MSPaint (i.e. Process 2)");
                 StartProcess2();
                 Console.WriteLine("MSPaint Stopped. Press Enter to Exit");
                 Console.ReadKey();
           }

           static void StartProcess1()
           {
                  Process proc = new Process();
                  proc.StartInfo.FileName = "Notepad.exe";
                  proc.Start();
                  Console.WriteLine("Notepad running...");
                 proc.WaitForExit();
           }

           static void StartProcess2()
           {
                Process proc = new Process();
                proc.StartInfo.FileName = "MSPaint.exe";
                proc.Start();
                Console.WriteLine("MSPaint running...");
                proc.WaitForExit();
