ODBC ann password dialog

Hi!

I am using Ingres database 6.4. There is installed IngresNet and ODBC
driver in my PC. UserName and Password are properly in their own places.
I am using Delphi4 and FormulaOne spreadsheet component. I can't use
TDatabase component because FormulaOne Spreadsheet uses its own ODBC
commands. Every time when I connect first time to Ingres server the
password dialog appears
unnecessarily on the screen. When I press the return key I get further.
How can I tell to application that necessary username and password are
stored in IngresNet?
