The Admin COM component serves the CML administrator (through the ASP page Checkin.asp) by providing methods that check library materials in and out and renew checked-out items. To perform some of its tasks, the Admin object calls stored procedures that do the actual database work. This is a diagram of the Admin component:
As is the case with all COM components, Admin supports the IUnknown and IDispatch interfaces. You can learn more about these interfaces in reference materials about COM programming or component creation with Microsoft Visual Basic®. You can also query for these topics in the Microsoft Platform SDK. For information on the other interfaces exposed by this component, see Automatic Object Interfaces.
