A problem with my free login form design with vb code.

Hello friends,
A problem with my free login form design with VB code. I got some sample template for a login form design which is composed with visual basic codes.
This is for my department store log in form administrator, and it seems like the password and username didn’t match to each other. Can you share some other VB coding technique for a log in system page?
Thanks and Regards,
Shannon Larry.
