OK, I see how to access the Example databases, including the one that's
in Access format.
But how do I access my own Access .mdb database? When I run the
OpenSQLConnection wizard and specify to use ODBC(DSN), I'm asked to
enter the DSN. What's that? And where do I enter the actual location
of my Access database?
