>We have a client that uses MS Access to query our Foxpro for Windows version 2.6 database. We have just upgraded the database to VFP 5.0 and now the Access queries no longer work. They get an invalid operation error. Do we have to query VFP tables different from Foxprow 2.6?

You probably need to use an updated ODBC driver; the query should work the same way, but the ODBC driver needs to understand Fox's .DBC and extedned data and index types that didn't exist in FPW 2.6
