Visual Basic 2010 offers a great deal of functionality in both tools and language. No one book could ever cover Visual Basic 2010 in its entirety-you would need a library of books. What this book aims to do is to get you started as quickly and easily as possible. It shows you the roadmap, so to speak, of what there is and where to go. Once we've taught you the basics of creating working applications (creating the windows and controls, how your code should handle unexpected events, what object-oriented programming is, how to use it in your applications, and so on) we'll show you some of the areas you might want to try your hand at next.

Visual Basic 2010 offers a great deal of functionality in both
tools and language. No one book could ever cover Visual Basic 2010
in its entirety--you would need a library of books. What this
book aims to do is to get you started as quickly and easily as
possible. It shows you the roadmap, so to speak, of what there is
and where to go. Once we've taught you the basics of creating
working applications (creating the windows and controls, how your
code should handle unexpected events, what object-oriented
programming is, how to use it in your applications, and so on)
we'll show you some of the areas you might want to try your
hand at next.
