ADO Connectstring, DSN-less OLEDB ADO can be used via ODBC or OLEDB drivers. OLEDB drivers generally gives somewhat better performance

Function Incdb_GetConnectionString( nNumber )
    Incdb_GetConnectionString = "Provider=Microsoft.Jet.OLEDB.3.51;Data Source=" & Server.MapPath("\database\ad2000.mdb")
End Function
This code uses version 3.51 of the Access OLEDB driver to connect to the database. There is a newer ( and better/faster) version called 4.0 as well. That driver can however only be used to connect to Access 2000 database files, not Access 97 files, so, use this table to work the version problem out: ( the database file is called db.mdb and is located under the /database/ directory )
