Rod Stephens, president of Rocky Mountain Computer Consulting, Inc., is the author of more than 20 books and 250 articles about various programming topics. Rod has been a professional developer for more than 20 years during which time he has worked on an eclectic assortment of applications in such diverse fields as telephone billing, fuel taxes, waste water treatment, and professional football. Rod’s VB Helper Web site receives roughly 200,000 visits per month and provides more than 2,000 examples demonstrating specific programming techniques in Visual Basic, while his CSharpHelper Web site contains similar examples for C# programmers. Altogether, Rod’s writing, teaching, programming, and web site experience will be invaluable in making this book far more than a “term and concept” reference—the book will also stand on its own, providing the critical background information that the other books in the series would not have sufficient room to deliver.
