but it now seems that its not easy to feed text into a cmd window.

private void btnKapow_Click(object sender, EventArgs e)
{
    Process Temp = Process.Start("C:/Windows/System32/cmd.exe");
    Temp.StartInfo.UseShellExecute = false;
    Temp.StartInfo.RedirectStandardInput = true;
    //Temp.StartInfo.RedirectStandardOutput = true;
    //Temp.StartInfo.RedirectStandardError = true;
    Temp.Start();
    Temp.StandardInput.WriteLine("Test");
    Temp.Close();
}

1. How is the program invoked manually from a command window.
2. What, if any, further input commands do you need to type in to the program.
3. What output is produced by the program on the command window, that you need to capture.
4. What command, if any, is used to terminate the program.
