Answer 1

I'm not sure how kosher it is to answer your own question, but I found a connection string that is more what I'm looking for:

"Driver={Microsoft ODBC for Oracle}; " & _
                                 "CONNECTSTRING=(DESCRIPTION=" & _
                                 "(ADDRESS=(PROTOCOL=TCP)" & _
                                 "(HOST=myserver)(PORT=1521))" & _
                                 "(CONNECT_DATA=(SERVICE_NAME=servicename))); " & _
                                 "uid=username;pwd=password;

With 10g, you can use the EZCONNECT feature. To connect to an Oracle instance named ORCL on the server myServer, the connection string would look like this :

Driver={Microsoft ODBC for Oracle};Server=myServer:1521/ORCL;Uid=myUsername;Pwd=myPassword;

You need to add an entry in your tnsnames.ora file for the service to which you want to connect. Alternatively, you can go to the gui interface for that file at

Start->Programs->Oracle->Configuration and Migration Tools->Net Configuration Assistant

and set up your oracle connection there. Then, ODBC will be able to resolve the service name.
