Hi Craig,

thanks for laying it out so clearly.

In VFP, you get back recordset if you use OLEDB directly. If you use a CursorAdapter, it converts the RS to a cursor for you.

>3. You *can* use the "ODBC Driver for OLEDB". This is the ONLY case where OLEDB sits between ODBC and the database. In this case, the application connects to ODBC, ODBC connects to OLEDB, and OLEDB connects to the database. The only time I would ever use this is when the application requires ODBC and you have to use OLEDB to connect to the database.
