Interface IEventTrigger

Description

This interface is exported by Trigger event objects.

IEventTrigger derives from IEvent.

Methods

GetAttribute

Use of this method is discouraged. All the non-deprecated standard attributes are accessible via properties on the appropriate COM interfaces.

SetAttribute

Use of this method is discouraged. All the non-deprecated standard attributes are accessible via properties on the appropriate COM interfaces.

Close

Closes the resource. Sending the resource's COM object's reference count to zero (and thus destroying the object) also executes a close, but this method may be useful for environments with garbage collection or other facilities that make object lifetimes non-deterministic.
