We have the enterprise edition, but we code the alias in. I think this will work in standard. You'll need to add an ODBC connection, either through the control panel (ODBC Administrator) or through some install tool. This is the code we use for an ODBC connection to Access.
LSTRS_Parameters := TStringList.Create;
If Session.IsAlias('Cars_AIS_Maindb') then
Session.DeleteAlias('Cars_AIS_Maindb');
LSTRS_Parameters.Add('DATABASE NAME=H:\data\046\chicago\carsdb\Main.mdb');
LSTRS_Parameters.Add('ODBC DSN=Cars_Ais_Maindb');
Session.AddAlias('Cars_AIS_Maindb', 'Microsoft Access Driver (*.mdb)', LSTRS_Parameters);
LSTRS_Parameters.free;
}
