Pascal,
You could write one or more COM components that would accept requests over your RAS connection and return data. That could be a lot of work and it seems to me you would still need to re-write or at least modify the front-end application. You may want to consider SQL Server or MSDE (the MS Data Engine, available by download from the MS web site).
Of course, if you just need a simple application that does a few queries to work over the RAS connection, creating COM components may be the way to go.

>I want to access a VFP database over a RAS/ISDN connection which means slow speed. So I was wondering : if I could send an SQL command over to the remote side, processing is done at the remote side and not over the RAS connection, an the result is sent over, the connection wouldn't be charged for processing, only for exchanging the data ...
