Thread: Auto destroy .Net Extension based on extension event.

Auto destroy .Net Extension based on extension event. Your last visit to this thread was on 1/1/1970 12:00:00 AM

Instead of calling the command
Application.Managed.Destroy ext
to destroy the loaded .Net extension is there a way to have the .net extension destroy itself on a particular event in the extension?

For instance say i have a phone dialer that is called on a click event in an account form. It then monitors the call for various stats like time it took to ring, busy signal, duration of call. On a disconnect event I write to a table all the pertinent details and would like to destroy the .net extension. If i call destroy in Architect after run the extension no longer monitors all the events.

Erdem,

The problem with what you propose is that the .net extensions manager holds a reference to your component. You access this component through the Guid that is provided. Objects do not dispose themselves as this is bad design, the parent that created them is responsible for the disposal, if if they are locally scoped then the garbage collector would dispose them when the callee was out of scope. It also sounds like to me you want your core entension to be around listening and have the internal handlers be disposed. If that is the case then make your extension a simple event handler and create and dispose inner types at will.

Thanks for the quick reply.

When the phone connection registers as disconnected all the internal handlers are disposed. So it sounds like if I do not destroy it in SLX I am fine since it should be disposed by the garbage collector.
