Please try again. I have no idea what you are asking.

I think this will work for you:

Imports System.IO
Module Module1

    Sub Main()
        'This sets up and starts the cmd window
        Dim MyApp As Process = New Process()
        MyApp.StartInfo.FileName = "cmd"
        MyApp.StartInfo.RedirectStandardInput = True
        MyApp.StartInfo.UseShellExecute = False
        MyApp.Start()
        'This sets up the cmd window to read your commands
        Dim MyInStream As StreamWriter = MyApp.StandardInput
        'send your commands like this.  Put any command that cmd will 
        'normally execute into a string and use MyInStream.WriteLine() method
        MyInStream.WriteLine("cd c:\")
        MyInStream.WriteLine("test.txt")
        'With this loop the app won't exit until you close the cmd window
        While Not MyApp.HasExited

        End While
    End Sub

End Module

Because the input is redirected, the cmd window won't accept any input from the keyboard, only from the code.
