If you are asking position and how to use check this link: https://zone.ni.com/reference/en-XX/help/371361K-01/lvhowto/creating_user_events/

-Event structure has tw types of registering events static and dynamic.

-In static event registration is performed automatcially when a VI with event structure is run for all the user interface events.

-Whereas Dynamic event registration is custom user based and without user interaction you can create an event based on predefined condition.

-Create user event is used to define the event type and the cluster input name is what becomes event name.

Thanks udka!

Sorry for my out of focus question!

I found that I can just use event register function to to define the event,so I don't know the necessary of the create function? so as to destroy function.

Best regards,

You can define the listening part to an event in register for events.
-Create and destroy functions are required for user events.
-if you are still talking about front panel events registration, yes you can do dynamically register for events and you don't need create and destroy user event: https://zone.ni.com/reference/en-XX/help/371361K-01/lvhowto/dynamic_register_event/
-If you can post vi/snippet it might explain a bit better of what you are asking.
