Can anyone give me a code example that will help me access a stored parameter query in an access database from the ADO Datacontrol?

I have a list of projects loaded in a listbox. You click a project in the list and retrieve its number. i want to pass this number to the ADO datacontrol and in turn execute the stored query that returns a recordset based on the passed project number. these the results are in turn loaded into a 3rd party grid.

sounds simple enough, but i've looked everywhere to find out how to do this with no luck at all.

Thanks in advance
