For example, suppose I've declared a class Polygon and I want to derive from it a subclass Rectangle.
Polymorphism is achieved through a clever naming convention applied to source code.
However, more that just source code is involved. ClassAssist keeps all classes in a structured library that can be shared across a network. ClassAssist's Class Explorer window is the gateway into the ClassAssist IDE, a structured collection of windows through which you create and edit classes, their properties, and their methods. That is, if you edit a ClassAssist-generated class from VB 4.0, ClassAssist sees the change and asks if you want to pass your edits on to the ClassAssist library.
