Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create(""), HttpWebRequest)
Dim myHttpWebResponse As HttpWebResponse
' Display the 'HaveResponse' property of the 'HttpWebRequest' object to the console.
Console.WriteLine(ControlChars.Cr + "The value of 'HaveResponse' property before a response object is obtained :{0}", myHttpWebRequest.HaveResponse)
' Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.
myHttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
If myHttpWebRequest.HaveResponse Then
    Dim streamResponse As Stream = myHttpWebResponse.GetResponseStream()
    Dim streamRead As New StreamReader(streamResponse)
    Dim readBuff(256) As [Char]
    Dim count As Integer = streamRead.Read(readBuff, 0, 256)
    Console.WriteLine(ControlChars.Cr + "The contents of Html Page are :  " + ControlChars.Cr)
    While count > 0
        Dim outputData As New [String](readBuff, 0, count)
        count = streamRead.Read(readBuff, 0, 256)
    End While
'  Close the Stream object.
' Release the HttpWebResponse Resource.
    Console.WriteLine(ControlChars.Cr + "Press 'Enter' key to continue..........")

    Console.WriteLine(ControlChars.Cr + "The response is not received ")
End If
