Can any VB gurus out there PLEASE help me??

I am desperatley trying to find out how to utilize a database in an application I am trying to develop.
Basically all I need to do is assign 2 values from a .MDB database to 2 variables based on the input of a textbox (which is used as the search field in the database)there are 6 databases which I want to select from an option box for each. Each DB has three fields for each record,once the correct database has been selected, you enter the value for the search field in the text box, the database is searched for a match in the search field and the other 2 values are assigned to variables from the other 2 fields. This all goes on behind the scenes and the variables are then used in calculations.

All I can find is references to creating,appending,sorting,and displaying DB info. Please help my poor soul or im going to end up in the "Big House"!!
