I'm not sure, but you may try to use SQL low-level functions. They all work using ODBC. Use following string for SQLStringConnect VFP function:
Server=MYSERVER;Driver=MicrosoftAccess Driver;UID=myneme;Passowrd=mypassword;Database=MyDatabase
Database may be with path. Above may require additional parameters, that are special for Access. I'm also not sure about MS Access ODBC driver name.
Than, SQLConnect(). Than, SQLExecute to run SQL Update command for Access table and transfer data.
