I'm don't quite understand what you want to do. If you have a VFP 8.0 app, why not access the data natively? See my other comments interspersed below...

OLEDB is a low-level (read C) interface for access data. ADO is simply a COM wrapper around OLEDB. A CursorAdapter can connect to several types of data and handle the translation to VFP cursors automatically.

In general, OLEDB will be faster than ODBC because ODBC has additional overhead. Also, the VFP ODBC driver has not been updated since VFP 6.0. If your data has any features added since then (for example, AutoInc), then you will not be able to use ODBC.
