>>Hello Group,
>> When I pass a bad username and password to the following code I get the messagebox that "Connection Failed" but the error handler was not involked. When I send correct username and password it connects. Why isn't an error raised. I am reading Doug Hennig as we speak but it is sinking in slowly.
