Chapter 4. GUI Design and Event-Driven Programming

The first three chapters of this book introduced you to the basics of designing applications with Visual Studio 2010 and the components of the Visual Basic language.

You also know how to write functions and subroutines and how to call the functions and subroutines that are built into Visual Basic.

In this chapter, you'll design a few more Windows applications—this time, a few practical applications with more functional interfaces and a bit of code that does something more practical. You'll put together the information presented so far in the book by building ...
