How can I re-direct the output of a batch to the textbox1 in VB 2010 Express?

So I have researched this for about 3 days now and everything that I find doesn't work or throws 10+ Errors. I am trying take the output from a batch file (CMD Window that shows generated strings) and insert it into TextBox1 on my VB Form1. So when I push the button, the batch is executed which opens up (on toolbar) a CMD window, shows the strings as they are produced while being inserted into what might be an open file dialog but for now its textbox1.(multiline)
Is there a way to do this and/or is this where create pipeline comes in? I apologize in advance I am a week old beginner. Below is what I have for button1.

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Shell("C:\Test.bat")

    End Sub

    Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
        Dim myprocess As New Process
        Dim StartInfo As New System.Diagnostics.ProcessStartInfo
        StartInfo.FileName = "cmd" 'starts cmd window
        StartInfo.RedirectStandardInput = True
        StartInfo.RedirectStandardOutput = True
        StartInfo.UseShellExecute = False 'required to redirect
        StartInfo.CreateNoWindow = True '<---- creates no window, obviously
        myprocess.StartInfo = StartInfo
        myprocess.Start()
        Dim SR As System.IO.StreamReader = myprocess.StandardOutput
        Dim SW As System.IO.StreamWriter = myprocess.StandardInput
        SW.WriteLine(TextBox1) 'the command you wish to run.....
        SW.WriteLine("exit") 'exits command prompt window
        txtResults.Text = SR.ReadToEnd 'returns results of the command window
        SW.Close()
        SR.Close()
    End Sub
End Class
