how to set ODBC in my app? any sample codes?

thank you!

Your question is a little unclear. Have you looked through the "Database" article section on this site? It will probably answer a lot of your questions.

thank you, sir.
Well, I want to set(create) ODBC DSN... by myself with my program.
what should I do?
Sorry, My English is poor.

Take a look at the ODBC API function ::SQLConfigDataSource().

You can search the Discussion Board for this too as there have been other questions on how to use this function.

Are you using MFC?
