For data aware components (and probably for others too),
Application.OnException is the only place, otherwise you cannot trap
exception that are no caused by your program flow but by intrinsic
processing by the component (e.g. during post the database could reject
the data due to failed constraints, you could trap BeforePost or
AfterPost but not DuringPost).
