IEventSystem2 interface

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.

Because IEventPublisher and the publisher object are no longer supported, IEventObjectChange is not called on the ChangedPublisher method.


The IEventSystem2 interface inherits from IEventSystem. IEventSystem2 also has these types of members:


The IEventSystem2 interface has these methods.

Method Description
GetVersion Retrieves the version number of the event system.
