Hi Kieu, AutoInstantiated object have lifecycle like a structure. So it will get garbage collected when there are no more references to the object.

Roland points out a great way to understand WHEN that happens => MessageBox in its destructor event.

The best way to answer this would be to put a messagebox in the destructor event and run the app.

Hi Kieu;

    Yes ... eventually - most likely when the App finally  shuts-down or your app explicitly calls the GarbageCollect() command.
