How to send backspace using sendmessage (C #) in cmd.exe

I am trying to send keystrokes to cmd.exe that I run from my application. With this I can send all the keyboard characters, but if I try to send Backspace, this does not seem to take effect. The following is a snippet of code for sending cmd.exe messages:

SendMessage((int)shell.MainWindowHandle, WM_KEYDOWN, ((int)e.KeyCode), 0);
SendMessage((int)shell.MainWindowHandle, WM_KEYUP, ((int)e.KeyCode), 0);

Any idea why this won't work? What is the best way to send stdin from cmd.exe from a C # application?

You will need P / Invoke SendInput () , because Backspace is handled directly using the keyboard driver.
