อยากทราบวิธีดึงข้อความบนเว็บมาใส่ TextBox บน VB.NET ครับ

Imports System.Net
NotInheritable Class Program
	Private Sub New()
	End Sub
	Private Shared Sub Main()
		Using client As New MyClient()
			client.HeadOnly = True
			Dim uri As String = "http://www.google.com"
			Dim body As Byte() = client.DownloadData(uri)
			' note should be 0-length
			Dim type As String = client.ResponseHeaders("content-type")
			client.HeadOnly = False
			' check 'tis not binary... we'll use text/, but could
			' check for text/html
			If type.StartsWith("text/") Then
				Dim text As String = client.DownloadString(uri)
				Console.WriteLine(text)
			End If
		End Using
	End Sub

End Class

Class MyClient
	Inherits WebClient
	Public Property HeadOnly() As Boolean
		Get
			Return m_HeadOnly
		End Get
		Set
			m_HeadOnly = Value
		End Set
	End Property
	Private m_HeadOnly As Boolean
	Protected Overrides Function GetWebRequest(address As Uri) As WebRequest
		Dim req As WebRequest = MyBase.GetWebRequest(address)
		If HeadOnly AndAlso req.Method = "GET" Then
			req.Method = "HEAD"
		End If
		Return req
	End Function
End Class

using System;
using System.Net;
static class Program
{
    static void Main()
    {
        using (MyClient client = new MyClient())
        {
            client.HeadOnly = true;
            string uri = "http://www.google.com";
            byte[] body = client.DownloadData(uri); // note should be 0-length
            string type = client.ResponseHeaders["content-type"];
            client.HeadOnly = false;
            // check 'tis not binary... we'll use text/, but could
            // check for text/html
            if (type.StartsWith(@"text/"))
            {
                string text = client.DownloadString(uri);
                Console.WriteLine(text);
            }
        }
    }

}

class MyClient : WebClient

    public bool HeadOnly { get; set; }
    protected override WebRequest GetWebRequest(Uri address)
    {
        WebRequest req = base.GetWebRequest(address);
        if (HeadOnly && req.Method == "GET")
        {
            req.Method = "HEAD";
        }
        return req;
    }
