Generate primary keys

Hi,
I'm using the SQL enterprise manager to build a database that acts as a back-end to a vb application i've been using.

I'm trying to figure out how to auto-generate primary keys (I would prefer doing it via gui) . . How do I do this?

Thanks,
Kelly

execute a Stored Procedure from within VB. The stored procedure can alter a table or create a new one with primary keys.
