displaying filtered data based on intermediary table in visual studio 2008

I have a small project I’m trying to do in VB.net

I have a simple database I have a number of users and a number of tasks, I have an intermediary table of foreign keys User_tasks.

I want a simple form that Displays the Task field of the tasks table filtered by the Task ID being present in the user_tasks table, Itself filtered by UserID from the users table

I can get users_tasks in a combo box to filter based on customer ID but not the implied list of tasks a user could perform.
