With such an acclaimed list of contributors that include Bob Swart (aka Dr. Bob) and Ray Konopka, it's little wonder that Delphi 6 Developer's Guide oozes knowledge and insight from cover to cover. Make no mistake, this is not one for the faint-hearted. If you are just starting out along the development road, then you may well do better to pass this volume by for now. However, if you are looking to step up your skills to get to grips with the advanced end of Delphi, then this book will take you.
