This book is an expanded and updated edition of Clay Shannon's previous book, Developer's Guide to Delphi Troubleshooting, which received the following praise:
"One specialized reference I found particularly useful was Clay Shannon's Developer's Guide to Delphi Troubleshooting, which is essentially an encyclopedia of Delphi error messages. If you've been programming for years in Delphi (or Turbo Pascal, for that matter), you'll encounter some 'old friends' here. At first I wondered if there would be anything new for me. I didn't have to wait long. Within a few days of receiving this valuable reference, one of the error explanations saved me hours of needless effort in getting an API call to work.

The revised The Tomes of Delphi: Developer's Guide to Troubleshooting covers all versions of Delphi, including Delphi 6. This book is an alphabetical reference to nearly 800 design-time, compile-time, and run-time error messages of Borland's Delphi Object Pascal language. Error message entries include an explanation of what actions or omissions may have caused the error message, how to quickly resolve the problem, and how to avoid receiving the error message in the future. Code samples clearly demonstrate how to eliminate the errors.
