When you're finished playing with the program, click the Quit button to return to Design view.
That's it! You've just created a bona fide Visual C# program. You've used the toolbox to build an interface with which users can interact with your program, and you've written code in strategic event handlers to empower your program to do things. These are the basics of application development in Visual C#. This fundamental approach is used to build even the most complicated programs; you build the interface and add code to make the application do things. Of course, writing code to do things exactly the way you want things done is where the process can get complicated, but you're on your way.
If you take a close look at the organization of the hours in this book, you'll see that I start out by teaching you the Visual C# (Visual Studio 2008) environment. I then move on to building an interface, and later I teach you all about writing code. This organization is deliberate. You might be a little anxious to jump in and start writing serious code, but writing code is only part of the equation—don't forget the word Visual in Visual C#. As you progress through the hours, you'll be building a solid foundation of development skills.
Soon, you'll pay no attention to the man behind the curtain—you'll be that man (or woman)!
