Trying to get stock data from webservicex.net

My textbox never gets any data:

Code:

---

Imports System
Imports System.IO
Imports System.Net
Imports System.Text

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim request As HttpWebRequest
        Dim response As HttpWebResponse = Nothing
        Dim reader As StreamReader

        Try

            request = WebRequest.Create("http://www.webservicex.net/stockquote.asmx?F")
            request.Method = "POST"
            ' Get response 
            request.ContentType = "text/xml"
            request.Headers.Add("SOAPAction", "http://webserviceX.NET/GetQuote")

            response = DirectCast(request.GetResponse(), HttpWebResponse)

            reader = New StreamReader(response.GetResponseStream())
            txtOutput1.Text = (reader.ReadToEnd())

        Finally
            If Not response Is Nothing Then response.Close()
        End Try

    End Sub
