Thanks guys,

This will do the trick. One more thing how do i disable the ODBC Login Dialog.
If ORACLE SERVICE or TNS Listener are not running then before i display user with my messagebox, ODBC login prompt comes up. I know i can disable this but only if connection is established.
expl. SQLSETPROP(cConnectionHandle, 'DispLogin', 3)
Any ideas how to avoid this?

Thanks

Dejan
