UserInfo is a COM component that is downloaded to the client and run there. For more information about this process, see CML Data Access Using RDS. This is a diagram of the UserInfo component:
Like all COM components, UserInfo supports the IUnknown and IDispatch interfaces. You can learn more about them 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.
UserInfo's CML-specific functionality is provided by the UserInfo interface. This interface has two Get properties and no methods.
