Chapter 7. Superclassing
This chapter is divided into two sections. The first section deals strictly with defining and comparing superclassing to subclassing. The second section takes a closer look at using only the Windows application programming interface (API) from within Visual Basic (VB) to create a window class and instantiate a window from that class. This material will not only discuss the use of several APIs required for superclassing within VB, but it will also give a better look into message loops and window creation. I will provide an example, written strictly in VB, to demonstrate superclassing from start to finish.
