Hi - I'm looking to build an addin that can register with a view window to be notified when its extent changes due to a user panning or zooming. Upon catching this event, I need to read the graphic elements that are shown in the view window after the extent change has occurred. From what I've been reading, it appears that if this can be done, it's likely only possible in C++ so I can switch to that language if that's the case.
Thanks,
Martin
