I think with remote views, it still access the tables, but just does not open it in your application, but rather in the ODBC driver for VFP.

I've preached before about using remote views to hit VFP tables so that all you have to do is change the connection string and then have all your remote views point to something else like SQL Server or Oracle. Of course most people are not going to create their VFP apps that way from the onset. Even so I would *think* that even if you had to deal with such an issue that it would probably still be less time consuming than doing a total re-write to something like C#. I guess it would require doing an analysis to determine if it's worth doing and its going to be different for every case.
