RegisterEvent question

[help137]

Does anyone know what happens if you register an event you've already got registered? or Unregister one that isn't registered? Will the UI throw an error? Call the associated event handle twice? Etc, etc?

I have registered a event multi times by accident. Normally happens when I start coding out of my head and don't check what i have done. I have never seen any adverse effects.

As far as unregistering a event I don't think so. You can't unregister what isn't there and I think it just overlooks this.

No error will occur in both cases. It will just fail silently.
