How do I send a POST to a website and receive a response in VB?

Dim text As string = "The following procedure describes the steps used to send data to a server. This procedure is commonly used to post data to a Web page."
 
Dim result As String = ""
Dim myrequest As HttpWebRequest = HttpWebRequest.Create("http://www.gizoogle.net/textilizer.php")
myrequest.Method = "POST"
myrequest.Timeout = 1000
myrequest.ContentType = "application/x-www-form-urlencoded"
 
Dim bytedata As byte() =  Encoding.UTF8.GetBytes("translatetext="& text &"translate=Tranzizzle+Dis+Shiznit")
myrequest.ContentLength = bytedata.Length
 
Dim requestStream As Stream = myrequest.GetRequestStream()
requestStream.Write(bytedata, 0, bytedata.Length)
requestStream.Close()
 
Try
   Dim resp As System.Net.HttpWebResponse = myrequest.GetResponse()
 
   Dim sr As New System.IO.StreamReader(resp.GetResponseStream())
   result = sr.ReadToEnd()
   sr.Close()
 
   Dim re As RegEx = new RegEx("<textarea.*?name=""translatetext"".*?>(.*?)</textarea>")
   Dim m As Match = re.Match(result)
   
   If m.Success
   		result = m.groups(1).Value
   End If
 
   Console.WriteLine(result)
Catch ex As WebException
   If ex.Status = WebExceptionStatus.Timeout Then
       result = "Error: The request has timed out"
   Else
       result = "Error: " + ex.Message
   End If
End Try
