Create a simple VB.NET 2008 login system

Basically, I would like someone to create a simple VB2008 project that will show me how to create a simple login system, where the user has to enter a username and password, the program will check the info entered against an access database and if invalid show a failure message else show a form with their login name displayed in a label in the status bar. I would like the ability to add new users to the database by filling in a form. The? main difficulty I have in understand this is how I connect to the database, but if you put comments in the script I would understand it better. Thanks, Andrew
