Event Handler in Delphi

[Phoenix]

Nope. As the compiler says: In Delphi.NET you must use the Include/Exclude functions to add/delete Eventhandler. That's because in CLR you always have multicast delegates (you can add more than one handler to a single event at a given time), and Delphi does not know the += / -= syntax to add / remove a single handler from an event. So you have to use Include(Event, Eventhandler); or Exclude(Event, Eventhandler); instead of Event := handler; .
If you can understand a bit of german, then have a look at this excellent article from Sakura: http://www.delphipraxis.net/internal...=248261#248261
