Hi, I have looked at your video and i encounter some problem.

Code:

If TextBox1.Text = "" Then
            MsgBox("You must insert a code!")
        Else
            'Proceed

            Dim isvalid As Boolean = tw.ValidatePIN(TextBox1.Text)
            If isvalid = True Then
                Dim oauthToken As String = tw.OAuth_Token()
                Dim oauthtokensecret As String = tw.OAuth_TokenSecret()
            Else
                MsgBox("Wrong code!")
            End If
        End If

IT always return me false when button is clicked. Need help urgently
