The MS ODBC driver for Oracle installed by MDAC 2.6 has version 2.573.6256.00
I noticed that the manifest for the MDAC SP1 download has in it the ORACLE driver: msorcl32.dll 2.573.7326.0. I am assuming the the MDAC 2.6 is included with VFP7? I guess I read where the VFP odbc drivers were not included in the MDAC 2.6 SP1 release.
