Abstract

In the previous chapter you looked at how class hierarchies are created in Visual Basic. The chapter also introduced the concepts of inheritance, polymorphism, and interfaces. In this chapter you will look at how the objects of the application work together to perform the tasks required. You will look at how objects communicate through messaging and how application processing initiates through events. Another important concept reviewed in this chapter is how the objects respond and communicate exceptions that may occur as they carry out their assigned tasks.
