No introductory book can cover every programming topic. However, the topics this book does
cover give you a good foundation of fundamental programming skills that you can use as a base for
THE WROX 24-Hour Trainer APPROACH
Educators have known for many years that different people use different learning styles most effec-
tively. Personally, I learn best by watching and doing. However, different students may learn best by:
Reading a textbook
Looking at non-written material such as pictures and graphs
Listening to an instructor lecture
Watching someone demonstrate techniques
Doing exercises and examples
Good instructors try to incorporate material that helps students with all of these learning styles.
Combining text, lecture, demonstration, discussion, and exercises lets every student pick up as much
as possible using whichever methods work best.
Like a good instructor, this book uses materials that address each learning style. It uses text and ﬁg-
ures to help visual learners, screencasts that provide visual demonstrations and auditory instruction,
step-by-step instruction to help you do it yourself, and exercises for independent study.
The book is divided into small, bite-sized lessons that begin with a discussion of a particular concept
or technique, complete with ﬁgures, notes, tips, and other standard fare for instructional books. The
lessons are short and tightly focused on a single task so you can ﬁnish each one in a single sitting.
You shouldn’t need to stop in the middle of a lesson and leave concepts half-learned (at least if you
turn off your phone).
After describing the main concept, the lesson includes a Try It section that invites you to perform a
programming exercise to solidify the lesson’s ideas.
The Try It begins with a high-level overview. It then contains several subsections:
describes the exercise so you know what should happen.
gives pointers about possible confusing aspects of the problem (if they’re needed).
provides a numbered series of steps that show how to solve the problem.
A screencast on the accompanying DVD shows me (the author) working through the Try It problem.
Additional commentary at the end of the screencast highlights extensions of the lesson’s main concepts.
After the Try It’s Step-by-Step section, the lesson concludes with extra exercises that you can solve for
further practice and to expand the lesson’s main ideas. I recommend that you at least skim the exercises
and ask yourself if you think you could do them. Solutions to all of the exercises are available for down-
load on the book’s web site.

Actually the book has two web sites: Wrox’s version and my version. Both sites
contain the book’s source code.
To ﬁnd the Wrox web page, go to
www.wrox.com and search for the book by title
or ISBN. Once you’ve found the book, click the Download Code link on the book’s
detail page to obtain all the source code for the book. Once you download the code,
just decompress it with your favorite compression tool. Alternatively, you can go to
the main Wrox code download page at
to see the code available for this book and all other Wrox books.

Hints (if needed)
The one thing that a good classroom experience has that this book doesn’t is direct interaction. You
can’t shout questions at the instructor, work as a team with fellow students, or discuss exercises
with other students.
Although the book itself can’t help here, there are at least three things you can do to get this kind of
interaction. First, join the Wrox P2P (peer-to-peer) discussion forum for this book. As the section
“p2p.wrox.com” later in this introduction says, you can join the discussion forum to post questions,
provide answers, see what other readers are doing with the book’s material, and generally keep tabs
on book-related topics. (You can join other Visual C# discussion groups on the Web, too, but this
one is dedicated to this book and you know I’ll be watching it.)
Second, you can browse or subscribe to my blog at
blog.CSharpHelper.com to see new example pro-
grams, articles, and commentary. Many of the entries describe tips, tricks, and short example programs
that demonstrate techniques that you may ﬁnd useful for your Visual C# programs.
Finally, if you get stuck on an exercise or some other program you’re working on, e-mail me at
RodStephens@CSharpHelper.com. I won’t solve the exercises for you, but I’ll try to clarify problems
or give you any hints you need so you can solve them yourself.
