access query

[somersbar]

i am doing a project in visual basic using asp.net webforms and am
pretty new to it.
i have a webform thats linked to a microsoft access database. basically
the database contains 2 tables, Areas and Cinemas.
i have 2 dropdownlists in the webform. the first one is used to select
an area. once that has been selected i need to the second list to show
all the cinemas in that area. how do i go about creating this query in
my code?

any help appreciated.
