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
