how do I use an already created ODBC DSN?

[enk2005]

Hi, I'm new to Plesk and I would like to use the "create new ODBC DSN" function to connect to an Access database.
My Plesk software allows me to create it but I don't know how to manipulate this DSN programmatically once I create it. How do I connect to the DSN and manipulate the database associated with it?
I know how to create new ODBCs from scratch but I don't get how to use the ODBC connection created by Plesk.

I would appreciate any comments or help with this,

Thanks!
