VS 2010 : Get Output From Cmd Like Window Into Textbox?

What iam trying to make is an app that would automaticly start two other applications, where one of them needs a single key pressed as input, and copy some link to the clipboard.The application that needs some keys pressed in order to start is this LINK As you can see it looks like some CMD piece of application. i want the output from that window into a TextBox on my form, but have been unable to do that.Ive tried two methods allready.. The most described and used is the RedirectStandardOutput and RedirectStandardInput methods:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim p As New Process
RichTextBox1.Text = "* - Starting Modern Warfare 2 Server Admin Tool"

[code]....

2. This would also store a "log" as the textfile for later use.However the tricky part for me is to:

1. Get the output from the mw2sa.exe window to automaticly update the textfile every few seconds

2. Be able to read the textfile in the textbox. VB tells me its unable to read the textfile as it is beeing used.

3. Somehow if i use the

ProcID = Shell("cmd /K mw2sa.exe > log.txt", AppWinStyle.NormalFocus)

To launch the program all i get is a black cmd window.. However, a log.txt file is created with the correct output, but since the cmd window isnt showing any output i dont think im able to use sendkeys to start the program. And if i try with only

ProcID = Shell("mw2sa.exe > log.txt", AppWinStyle.NormalFocus)

I get the correct cmd window with all the right output. Sendkeys is also able to pass the key to start the program... But no log.txt is created!
