How to control value-class object destruction

I need to control destruction of a value-class object.

The problem is as following.

I have a some program (let's call it MyProg) that during execution creates a value-class object (lets call it MyValClass). MyValClass has a handle-class object as one of its properties (lets call it MyHandClass). That handle class initiates some events that MyProg listens to.

The problem appears is MyValClass object is destroyed (usually it happens on exceptions or user termination). I guess, that because there are still listeners listening to events of MyHandClass, the MyHandClass object is not destroyed, and remains in memory.

I would like to control the destruction of MyValClass object, so that I could implicitly delete its MyHandClass property. Is it possible?
