This class implements the IUccPresenceDeviceInstance and IUccCategoryInstance interfaces. The default interface is IUccPresenceDeviceInstance. An application obtains the default interface on the class instance directly. Non-default interfaces, if any, can be obtained by calling QueryInterface on the default interface. An instance of this class is also a source of the events defined in the _IUccCategoryInstanceEvents dispinterface. This class cannot be co-created. It is intended to illustrate that the implemented interfaces can be queried from each other as well as the events raised in an instance of this class.
