How to create ODBC DSN programmatically for Latest Oracle8.0.5.10?

hi all,
    May be some of you experienced before. My routine worked fine on
creating a run time ODBC DSN for Oracle 8.0.5.0.
via SQLConfigDataSource API. But it doesn't work properly with
Oracle80510 ODBC Driver.

any idea?

regards,
Teongchai
