Thank you, Nick. However, I don't know about TRUE/FALSE.
I did a quick test with this on Windows and when I hit Escape/click Cancel
from the DSN dialog, it returned SQL_NO_DATA.
So, I'm just thinking that all it needs to do is either return
SQL_SUCCESS when DSN is selected or different errors according to
SQLDriverConnect in MSDN.
