Used by the Microsoft Internet Explorer System Event Notification Service (SENS) to access the event data store. This interface extends the IEventSystem interface.
When to implement
You do not need to implement the IEventSystem2 interface. A system-supplied event system object (CLSID_CEventSystem) implements IEventSystem2.
When to use
If you use SENS, you can call the methods of IEventSystem2 to add and remove objects to and from the event store and to obtain objects from the event store.
The IEventSystem2 interface inherits from IEventSystem. IEventSystem2 also has these types of members:
The IEventSystem2 interface has these methods.
|GetVersion||Retrieves the version number of the event system.
|VerifyTransientSubscribers||Verifies the existence of all transient subscribers in the data store.
