ABOUT THE AUTHOR

IVOR HORTON started out as a mathematician, but shortly after graduating, he was lured into messing

about with computers by a well-known manufacturer. He has spent many happy years programming

occasionally useful applications in a variety of languages as well as teaching mainly scientists and engineers

to do likewise. He has extensive experience in applying computers to problems in engineering design and to

manufacturing operations in a wide range of industries. He is the author of a number of tutorial books on

programming in C, C++, and Java. When not writing programming books or providing advice to others, he

leads a life of leisure.

ABOUT THE TECHNICAL EDITORS

MARC GREGOIRE is a software engineer from Belgium. He graduated from the Catholic University of Leuven,

Belgium, with a degree in "Burgerlijk ingenieur in de computer wetenschappen" (equivalent to master of

science in engineering in computer science). The year after, he received the cum laude degree of master in

artiﬁ cial intelligence at the same university. After his studies, Marc started working for a big software

consultancy company called Ordina Belgium. As a consultant, he worked for Siemens and Nokia Siemens

Networks on critical 2G and 3G software running on Solaris for big telecom operators. This required working

in international teams stretching from South America and USA to EMEA and Asia. Now, Marc is working for

Nikon Metrology on 3D scanning software.

His main expertise is C/C++, and speciﬁ cally Microsoft VC++ and the MFC framework. Next to C/C++, Marc

also likes C# and uses PHP for creating web pages. In addition to his main interest for Windows development,

he also has experience in developing C++ programs running 24x7 on Linux platforms; for example, EIB home

automation controlling and monitoring software. Since April 2007, he's received the yearly Microsoft MVP

(Most Valuable Professional) award for his Visual C++ expertise.

Marc is an active member on the CodeGuru forum (as Marc G) and wrote some articles and FAQ entries

for CodeGuru. He also creates freeware and shareware programs that are distributed through his website at

www.nuonsoft.com , and maintains a blog on www.nuonsoft.com/blog/ .

AL SCHERER is a Development Manager of eCommerce Technologies at Follett Higher Education

Group. He has seven years of experience designing and coding applications as a Software Architect in

addition to 10 years of development experience. Al has built applications using Assembler, C, C++ and a

number of other programming languages and has worked extensively in Java since Version 1.1. He holds

Sun Java certiﬁ cations as a Programmer, Business Components Developer and Web Components Developer.

In his spare time, Al applies his passion for technology via technical writing and editing, working on nine

software books over the last few years. He holds a BS in Engineering from University of Illinois at

Urbana-Champaign and an MBA from Northwestern University.

ACKNOWLEDGMENTS

OF COURSE THIS BOOK is not all my own work. The John Wiley & Sons, and Wrox Press editorial and

production team transformed my draft into the ﬁ nished book. I'm especially indebted to Project Editor

Maureen Spears, who has been there from way back at the beginning and has been incredibly helpful

throughout. Charlotte Kughen has done a great job of untangling my grammar and identifying my

sometimes obscure references. I'd like to thank the Technical Editors for their thorough review of the

text and checking out all the examples in the book; their many constructive comments undoubtedly helped

make the book much better that it would otherwise have been.

As always, the love and support of my wife Eve has been essential for me to ﬁ nish this book. She remains

patient and cheerful, even when I am not necessarily the same.
