Re: [Pnet-developers] Destructors are not being called - bug or usage error?

[David Logan]

OK, technically I can respect that. But in oop-speak, I thought the idea was that code and data were self contained. That statement would mean that a class is responsible for its *own* cleanup. But now, by not requiring destructor calls, the requirement that a class execut its "shutdown code" or "cleanup code" has now been moved to the calling class, hasn't it?

At program termination, neither Form1.Dispose(bool)  nor ~GlobalSettings

The Form.Closed event is where cleanup operations like this will normally be 
placed.  You can also trap Application.ApplicationExit, or put the code just 
after your main call to "Application.Run".

While the engine should make the best effort to call all finalizers prior to 
exit, the standard makes no guarantee.  If you need something to happen on 
exit, then you must arrange for it to be called explicitly.

Cheers,
