CMD CommanderAutomate

[kshadow22]

My goal is to have my program run any command through CMD in the background and then display the results in a textbox. So far this program is functioning alright until it gets to a command that has a long response. For example, if I try to run "tasklist /m", my reply is blank because its too long. I am guessing this is the reason why my response is coming back with nothing since smaller codes such as just "tasklist" work. I have tried increasing the property for maxlength and going from a typical textbox to a richtextbox. Neither of those two changes solved my problem.
On my computer, the "tasklist /m" command has 68,391 char.

Here is my code that I am using. I would like to keep the same code with just a few adjustments, but if that isn't possible, I can make whatever work. I am just in need of any advice or complete help.

Public Class Form1
Private Results As String
    Private Delegate Sub delUpdate()
    Private Finished As New delUpdate(AddressOf UpdateText)

    Private Sub UpdateText()
        
        txtResults.Text = Results
    End Sub
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim CMDThread As New Threading.Thread(AddressOf CMDAutomate)
        CMDThread.Start()
    End Sub
    Private Sub CMDAutomate()
        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 cmd window
        myprocess.StartInfo = StartInfo
        myprocess.Start()
        Dim SR As System.IO.StreamReader = myprocess.StandardOutput
        Dim SW As System.IO.StreamWriter = myprocess.StandardInput
        SW.WriteLine(txtCommand.Text) 'the command you wish to run.....
        SW.WriteLine("exit") 'exits command prompt window
        Results = SR.ReadToEnd 'returns results of the command window
        SW.Close()
        SR.Close()
        'invokes Finished delegate, which updates textbox with the results text
        Invoke(Finished)
    End Sub
