Ciao a tutti,ho un problema nel effettuare il login sul mio sito,vi spiego qualcosa prima di postare il codice.
Ho realizzato 2 textbox e 1 bottone,dove nelle textbox ci sarà username e pass,il bottone dovrà mandare l'invio.

Il problema sta che non riesco a loggarmi,qualsiasi cosa poi scrivo,nell'username e pass mi da login effettuato

codice:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

        If TextBox5.Text = Nothing Then
            MessageBox.Show("Please enter your username")
            Button2.Enabled = True
            TextBox5.Select()
        ElseIf TextBox3.Text = Nothing Then
            MessageBox.Show("Please enter your password")
            TextBox3.Select()
        Else
            If Not TextBox5.Text Is Nothing And Not TextBox3.Text Is Nothing Then
                Me.Button2.Enabled = False
                MessageBox.Show("Ok, trying to LOG IN....")
                Try
                    'Address of URL
                    Dim URL As String = "http://mysite.com/login.php?username=" & TextBox5.Text & "&password=" & TextBox3.Text
                    Dim request As HttpWebRequest = CType(WebRequest.Create(URL), HttpWebRequest)
                    Dim response As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)


                    'Take a look at.>>
                    MessageBox.Show(response.StatusCode.ToString)


                    If response.StatusDescription = "OK" Then
                        MessageBox.Show("You are now logged in as user " & TextBox5.Text)
                        Me.Button1.Enabled = True
                    Else
                        MessageBox.Show("Login failed!!")
                    End If


                Catch ex As Exception
                    MessageBox.Show("The site is down, please try again later")
                    Me.Button2.Enabled = True


                End Try
            End If
        End If


    End Sub
End Class
