It isintended for novice programmers with little or no programming experience or no experiencewith Visual Basic. The text emphasizes programming logic and good programming techniqueswith generous explanations of programming concepts written from a nontechnical point ofview. It stresses input, processing, and output and sequence, selection, and repetition incode development. File input and output (I/O) and arrays are included. Later chaptersintroduce objects, event programming, and databases. By taking a slow and steady approachto programming ideas, this book builds new concepts from what the reader has alreadylearned. VB tips and quips inject both humor and insight.The book includes numerous programming examples and exercises, case studies, tutorials,and “Fixing a Program” sections for an in-depth look at programming problems and tools.Quizzes and review questions throughout each chapter get students to think about thematerials and how to use them. Each chapter has a summary and glossary for extra review.The accompanying web site has code downloads, I/O, and database files from small, simplefiles to large files with thousands of records, flowcharts, deskchecks, and audits to aid withprogram design, coding, and debugging, PowerPoint files for every chapter, and hundreds ofideas for programs and projects.Dr. Jim McKeown has spent more than 20 years at Dakota State University, where he isan Assistant Professor.

Who won aGrammy last year? Who pitched the last game of the World Series? How often dothe rich and famous make headlines for their good work, not their misdeeds? Thesepeople don’t impact your life so why is society obsessed them? And you certainlydon’t want to emulate many of them. Look around and find the ones that do impactyour life and pay attention to them.Thank you to the reviewers. Without their hard and sometimes thankless work,this book wouldn’t be nearly as good. I especially want to thank Rudy McDaniel forhis keen eye and suggestions.Thank you to Mrs. Heneghen, my first grade teacher, who taught me how to readand write and do arithmetic. She was a wonderful lady. Thank you to Mrs. Short.She instilled in me a love of learning I carry to this day. She’s still my neighbor andI’ve never been able to turn her down when she’s asked for a favor. Mrs. Pratt taughtme multiplication and division, Mrs. Moulton taught me science, and Mrs. Stuefenfirst taught me geography. I still love doing math in my head, studying science,and poring over maps. Miss Haggerty – there wasn’t a boy in the sixth grade thatwasn’t in love with her. I admired and respected Mr. Skovlund. Mr. Tordoff taughtme typing. I still use it every day, but he taught his best lessons with a whistle inhis hand. Mrs. Hefling was my English and speech teacher. I can make my livingthrough writing and speaking because of her. Mr. Magnus taught me algebra andphysics and always had time to answer questions. He was a good man. Mr. Vincentwas my history teacher and coach. His quiet dignity touched students for nearlyforty years. He made me a better person. Dr. Jerry Sweeney was my college advisor.He saw something in this skinny farm boy. Thank you to Anne Vollmer, NancyCunniff, and Howard Budin in grad school. Thank you to Dr. Jim Maxey. He wasa vice president at ACT but still had time to help me with my dissertation. Theseteachers made a difference in my life and I’ll never forget that.To Delores. See? Being a computer geek finally paid off. Now, I can start workingon the movie.Jim McKeownApril 3, 2009 in this web service Cambridge University Presswww.cambridge.org
