Controlling a command line program from a GUI

I could not reply to the original thread I found on this subject:
http://www.thescripts.com/forum/thread233220.html

But I found a great article that describes how to accomplish this goal.

private void start()
{
Process p = new Process();
StreamWriter sw;
StreamReader sr;
StreamReader err;

ProcessStartInfo psI = new ProcessStartInfo("cmd");
psI.UseShellExecute = false;
psI.RedirectStandardInput = true;
psI.RedirectStandardOutput = true;
psI.RedirectStandardError = true;
psI.CreateNoWindow = true;
p.StartInfo = psI;

p.Start();
sw = p.StandardInput;
sr = p.StandardOutput;
err = p.StandardError;

sw.AutoFlush = true;
if (tbComm.Text != "")
sw.WriteLine(tbComm.Text);
else
//execute default command
sw.WriteLine("dir \");

sw.Close();

textBox1.Text = sr.ReadToEnd();
textBox1.Text += err.ReadToEnd();
}
