Passing cmd.exe to textbox, missing Prompt line

Hello everyone,

I have started a project to integrate a command prompt into a forms app.
Borrowing code from here: http://stackoverflow.com/questions/1...e-using-vb-net
Having a form, with a separate class to handle the new process.

It is able to pass the StandardOutput to the text box, but it is missing the Prompt line, a.k.a the 'C:\>' at the end.
If you pass a command to it using StandardInput, the textbox will then show the Prompt line with your command afterwards.

But why not before? Is it due to that line not being 'complete' within cmd.exe, thus not being sent within the StandardOutput? Or would I have missed something in my code?

Appreciate the help! (:

Edit: Thought I would put in my code, so you know what I am working with ;)
