Acknowledgments
Many people contributed to this book, and I would like to thank them all. I guess I should start with the programmers at Microsoft, for their commitment to Visual Basic. Visual Basic has evolved from a small, limited programming environment to a first-class development tool.
Special thanks to the talented people at Sybex—to all of them and to each one individually. I’ll start with editor Pete Gaughan, who has taken this book personally and improved it in numerous ways. Thanks, Pete. Thank you to developmental editor Tom Cirtin, who has followed the progress of the book, its ups and downs, and managed to coordinate the entire team. To technical editors Jesse Patterson and Greg Guntle for scrutinizing every paragraph and every line of code. To production editor Kylie Johnston, who has done more than I can guess to keep this project in order and on schedule. To designer and compositor Maureen Forys, and everyone else who added their expertise and talent. Thank you all!
I’d like to thank and recognize Matt Tagliaferri for contributing Chapter 17, on exception handling.
I would also like to thank Alvaro Antunes and Harry Heijkoop for their helpful remarks while they were translating earlier versions of Mastering Visual Basic into Portuguese and Dutch, respectively.
