Remarks
Initialize the ListManager object before calling any other ListManager object method or property.
Initializing connects the ListManager object to a database. If the database does not contain the tables and procedures required by the ListManager object, they are created.
A ListManager object can be connected to only one database. To connect to a different database, instantiate a new ListManager object.
