Question

Here is some code that uses authentication using YouTube API.

Public Function GetService(ByVal username As String, ByVal password As String) As YouTubeService

        Dim service As YouTubeService = New YouTubeService("test", "xxxxxxxx")
        service.setUserCredentials(username, password)

        Return service

    End Function

Now if i type in some wrong credentials YouTube doesn’t specificity if the user is authenticate successfully. Is there another method to do this?

Answer 1
