You can assign a password to a database. You can specify the password to open a password-protected database in a workspace by using the password argument of the CreateWorkspace method.
In DAO 3.5, the Workspace object now also contains the Connection object, which contains information about a connection to an ODBC data source that uses an ODBCDirect workspace. For more information about ODBCDirect workspaces, see Chapter 9, “Developing Client/Server Applications.”
