In this chapter you've toured some of the most important controls used in typical Windows user interfaces. Even as I've introduced these staples, I've already started to show you how you can tweak and extend them with custom control classes. Developing custom controls is one of the key ways to tame these full-featured controls. You'll see more examples throughout the book, including Chapter 7, where you will tackle a directory browser TreeView that reads information from the underlying file system automatically.
