Is it possible to hook into the Destroy method of a component and actually prevent it from being removed from the Delphi 3 IDE?

I want to put in a verification routine, password dialog maybe, when a certain component is deleted.  If the verification routine fails, I don't want the component to be removed from the IDE.  I've tried raising exceptions but that causes a *lot* of problems with Delphi.

Thanks,
joe

Look at The ToolsAPI to hook into the IDE, Ray Lischner has a book on this "Hidden Paths of Delphi 3".

In Delphi 4, TObject will have a new protected method called BeforeDestruction.  I'm not sure that this will help you...the ide and streaming system expect your component to be gone...
