In my attached code...it starts and I get to the "Console.WriteLine section

How can I do this in a WinForm so that I can watch anything the listener pick up?

    Public Shared Sub SimpleListenerExample(inboundprefixes As String)
        If Not HttpListener.IsSupported Then
            MsgBox("Listener Not Supported", vbOKOnly, "Action")
            Return
        End If
        ' URI prefixes are required, 
        ' for example "http://someurl.com:8080/index/".
        If inboundprefixes Is Nothing OrElse inboundprefixes.Length = 0 Then
            Throw New ArgumentException("prefixes")
        End If

        ' Create a listener.
        Dim listener As New HttpListener()
        ' Add the prefixes. 
        ' For Each s As String In prefixes
        listener.Prefixes.Add(inboundprefixes)
        'Next

        listener.Start()
        Console.WriteLine("Listening...")
        ' Note: The GetContext method blocks while waiting for a request. 
        Dim context As HttpListenerContext = listener.GetContext()
        Dim request As HttpListenerRequest = context.Request
        ' Obtain a response object.
        Dim response As HttpListenerResponse = context.Response
        ' Construct a response. 
        Dim responseString As String = "<HTML><BODY> Hello world!</BODY></HTML>"
        Dim buffer As Byte() = System.Text.Encoding.UTF8.GetBytes(responseString)
        ' Get a response stream and write the response to it.
        response.ContentLength64 = buffer.Length
        Dim output As System.IO.Stream = response.OutputStream
        output.Write(buffer, 0, buffer.Length)
        ' You must close the output stream.
        output.Close()
        listener.[Stop]()
    End Sub

Mmmmm... place a TextBox with MultiLine property = true
Instead of Console.WriteLine(text) do TextBox1.Text += text + vbCrLf

Hope that helps.
