What I mean is, in VFP we can SET FILTER TO (some condition) and that filter will be in effect pretty much throughout the application. With NET we will have a query page that will establish the query (filter) and then return to some other page to view or print the data. How can we get the query or filter condition to persist through to the next page? Stuffing the SELECT statement and all of the parameters into a session variable seems like a clumsey approach as does trying to send a query string which would expose too much.
