Dim cookieContainer As New CookieContainer()
   Dim cookies As New CookieCollection()

   Private Sub Button1_Click_1(sender As Object, e As EventArgs) Handles Button1.Click
       Dim getUrl As String = "https://www.facebook.com/login.php?login_attempt=1"
       Dim postData As String = [String].Format("email={0}&pass={1}", "ايميل", "باسورد")
       Dim getRequest As HttpWebRequest = DirectCast(WebRequest.Create(getUrl), HttpWebRequest)
       getRequest.CookieContainer = New CookieContainer()
       getRequest.CookieContainer.Add(cookies)
       'recover cookies First request
       getRequest.Method = WebRequestMethods.Http.Post
       getRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2"

       getRequest.ContentType = "application/x-www-form-urlencoded"

       Dim byteArray As Byte() = Encoding.ASCII.GetBytes(postData)
       getRequest.ContentLength = byteArray.Length
       Dim newStream As Stream = getRequest.GetRequestStream()
       'open connection
       newStream.Write(byteArray, 0, byteArray.Length)
       ' Send the data.
       newStream.Close()

       Dim getResponse As HttpWebResponse = DirectCast(getRequest.GetResponse(), HttpWebResponse)
       Using sr As New StreamReader(getResponse.GetResponseStream())
           Dim sourceCode As String = sr.ReadToEnd()
           'MsgBox(sourceCode)
           RichTextBox1.Text = sourceCode
       End Using

   End Sub
