Yes giving them Read Only Access would do it. But the VFP app will probably have a long life, and the integrity of the data (which is rule intensive) is pretty crucial to the app running smoothly & happily ever after. So I'm thinking long term here - If I put my rules in a table fine & dandy, I got my 3 tiers nice and clean so long as the Read Only access never changes. And sure, I could do some power coding to put a little padding around that weak spot of ensuring RO access. But I see that as a lame cop out of making sure my data is always secure for the life of my app (no matter how long that is).
I guess what I'm getting at is I wouldnt want to adopt an implementation approach using a Rules Table validation technique unless I knew for sure that the real data tables in my dbc were just as protected as they would be using dbc field rules - no matter what network user rights happen to be.
