About the Authors
Tony Northrup
In the mid 1980s, Tony Northrup, CISPP, MCSE, and MVP,
learned to program in BASIC on a ZX-81 personal computer
built from a kit. Later, he mastered the 68000 assembly and
ANSI C on the Motorola VERSAdos operating system before
beginning to write code for MS-DOS. After a brief time with
the NEXTSTEP operating system, Tony returned to a
Microsoft platform because he was impressed by the beta
version of Microsoft Windows NT 3.1. Although he has
dabbled in other operating systems, Tony has since focused
on Windows development in Microsoft Visual C++, Visual
Basic, C#, and Perl (for automation projects). Tony now develops almost exclusively
for the .NET Framework.
Tony started writing in 1997 and has since published more than a dozen technology
books on the topics of development and networking. In addition, Tony has written
dozens of articles at http://www.microsoft.com, covering topics ranging from securing
ASP.NET applications, to designing firewalls to protect networks and computers.
Tony spends his spare time hiking through the woods near his Phillipston, Massachu-
setts home. He’s rarely without his camera, and in the past six years has created what
might be the largest and most popular publicly accessible database of nature and
wildlife photographs on the Internet. Tony lives with his wife Erica and his cat (also
his favorite photographic subject) Sammy.
