Class Construction and Destruction

It should appear to us clearly by now that inheritance is useful by allowing us to use an object that was already created but "upgrade" it with new features that were not available when the original object was born. In most cases, when creating a class, you may not thing that other classes would be inherited from it. In fact, this will usually not be your concern: you simply create a class and use it as needed. In some other cases, rather as you build your experience with Visual Basic. You may create a class that, although useful at the time, you may already think of other classes that would be based on it. This means that, at the time you are creating such a class, you would already keep inheritance in mind. Visual Basic provides various features that can assist you with creating and implementing class with different goals in mind.
