Writing applications for computer music, he discoveredthat he enjoyed designing and developing computer software. It wasn't long beforehe came to the realization that he stood a much better chance of eating if he stuckwith his new-found skill and demoted his hard-earned status as a "starving artist"to a part-time hobby. Since that time, Davis has focused on the art of software designand development, with a strong emphasis on the practical application of client/servertechnology.

Over the next 21 days, you will learn how to use the featuresthat Microsoft has built into its C++ development environment to enable you to createvery advanced applications for the Windows and NT platforms. When Microsoft's developersfirst came up with the idea behind Visual C++, they decided to take their world-classC++ compiler and create a development environment and set of tools that would enabledevelopers to create Windows applications with a level of ease and speed that wasunheard of among C++ development environments. Since that first version, Microsofthas continued to improve the tools that are a part of Visual C++ to make it eveneasier to create Windows applications. As Microsoft has introduced new technologiesinto the Windows platforms, it has also introduced tools into the Visual C++ suiteto make it easy to integrate these new technologies into your applications.</P><P>If you are new to C++, don't worry. I've tried to make it easy for you to learnthe C++ programming language while also learning how to build applications usingthe Visual C++ tools. Just in case you find yourself having trouble understandingsome aspect of C++, I've included a brief overview of the programming language inAppendix A, "C++ Review."</P><P>If you've looked at previous versions of this book, you might notice that I'vecompletely rewritten the entire book. Our goal with this new version is not justto introduce you to and guide you through the various tools and resources that youwill use to build applications with Visual C++; I've also tried to include a greatdeal more detail about the various options that are available to you with each ofthe features that are covered. This way, you'll be able to get a lot of use out ofthis book long after the initial 21 days.</P><P><H2><A NAME="Heading1"></A>How This Book Is Organized</H2><P>This book is organized in weeks, with each set of seven days set off into a partunto itself. However, even though the book is organized in weeks, the topics arenot neces-sarily organized that way.</P><P>For the first week, you'll be covering the basics of building applications withVisual C++. You'll learn how to use designers to design your application windows.You'll learn how to use various controls available to you as a Windows applicationdeveloper. You'll also learn a lot about the Visual C++ development environment andthe tools that it makes available to you.</P><P>By the time you begin the second week, you'll be doing more and more programming,as the topics become more involved. You'll still be using the Visual C++ tools toconstruct your applications, but the programming code will be getting a little moreinvolved. You'll also start learning about more advanced topics, such as displayinggraphics and creating SDI and MDI applications. Toward the end of the second week,you'll begin to work with databases. This topic spills over into the third and finalweek.</P><P>In the third week, you'll learn how to create your own modules, DLLs, and ActiveXcontrols. You'll also learn how to build multitasking applications, which performmultiple tasks at a time. Finally, you'll learn how to integrate Microsoft InternetExplorer, and the ActiveX controls it provides, into your applications so that youcan extend your applications over the Internet.</P><P>After you finish the third week, you'll be ready to tackle the world of Windowsprogramming with Visual C++. You'll have the skills and know-how required to buildmost Windows applications available today.</P><P><H2><A NAME="Heading2"></A>Conventions Used in This Book</H2><P>While you are reading this book, you will probably notice a couple conventionsthat have been used to make it easier for you to learn the topic being discussed.</P><P>All the source code in this book is provided in a monospaced font, as shown inListing 0.1. This includes all the source code from the applications that you willbe building and illustrations of how various functions can be used. Whenever youare adding new code, or changing code in a function with other code already there,the line numbers of the code that you add or change will be pointed out in the text.</P><P><H4>LISTING 0.1. SOME SAMPLE CODE.</H4><PRE>1: void main()2: {3: // if you are adding or changing code in an existing4: // code snippet, I will point out the line numbers in the text<B>.</B>5: }</PRE><P>If a topic needs special attention, it will be set apart from the rest of thetext by one of several special markers:</P><P><UL> <LI>Notes <P> <LI>Tips <P> <LI>Cautions</UL><P><HR><STRONG>NOTE:</STRONG> Notes offer a deeper explanation of a topic or explain interestingor important points.<HR></P><P><HR><STRONG>TIP:</STRONG> Tips are pieces of information that can make things easier.<HR></P><P><HR><STRONG>CAUTION:</STRONG> Cautions warn you about traps that you will want to avoid.<HR></P><P>At the end of each day, you'll find a short quiz and one or two exercises to helpmake sure that you learned the topic you were studying. Don't worry--just in caseyou need the answers to the quizzes and some guidance when building the exercises,the solutions are provided in Appendix B, "Answers."</P><P>Enough said! You didn't buy this book to read about this book. You bought thisbook to learn how to use Visual C++ to build Windows applications. So go ahead andflip the page and get started programming...</P><H1 ALIGN="CENTER"></H1><P><CENTER><P><HR><A HREF="../ch01/ch01.htm"><IMG SRC="../button/next.gif" WIDTH="128" HEIGHT="28"ALIGN="BOTTOM" ALT="Next chapter" BORDER="0"></A><A HREF="../index.htm"><IMG SRC="../button/contents.gif"WIDTH="128" HEIGHT="28" ALIGN="BOTTOM" ALT="Contents" BORDER="0"></A> <BR><BR></P><P>© <A HREF="../copy.htm">Copyright</A>, Macmillan Computer Publishing.
