Mr. Cantu has taken on an immense task condensing most of what you need to know about Delphi into a single volume. While he did a tremendous job of giving you a foundation of most aspects of Delphi, inevitably there are some areas in which you are left wanting.
I purchased this book for use at work, and for the most part - even if I have not found the exact answers to my questions - I have been able to determine the right "questions to ask" when it comes to formulating my Google queries to track down the answer I need. When it comes to Database Programming, I didn't find everything I needed in regards to ADO and had to get another book "Delphi Developers Guide to Programming with ADO" in order to make up for the sadly - very short section that Mr. Cantu devoted to the topic in this book.
Overall - this is an excellent companion for anyone who develops in Delphi. I must however offer one caveat - you will not find all of your answers here without the aid of Delphi developer websites, forums, Google, and other third party resources. I recommend this as a purchase if you understand that it is just a good reference. If you have a specialized need - I suggest trying to find your answers via the Delphi section on About.com or via DelphiBasics (download version). |
