Positioning itself in the middle ground between "weighty tomes" and "slimmer volumes" without enough reference material, this text concentrates on the features of the Professional Edition of the Delphi 6 programming language. After introducing the topic of object-oriented programming, computer programmer Eller offers chapters covering Object Pascal, Delphi's base elements, basic elements of an application, functions and procedures, program development techniques, Delphi and databases, Delphi and the Internet, developing components, and error-handling and debugging.

Discover Object Pascal, the basis for Borland's Delphi 6 development environment, and get togrips with it quickly. Addison-Wesley's Nitty Gritty Delphi 6 leads you right to the core ofDelphi. The author, Frank Eller, tells you about the most important classes and components.Thanks to the many examples in the practical section, you will quickly be able to understandhow things are done and how the different elements of Delphi work together, before putting theminto practice yourself.
Let's get down to the nitty gritty of:
Addison-Wesley Nitty Gritty Programming Series provides the most important facts that you willneed to know to get up and running in new programming topics quickly and when you have becomeproficient you can use it as an on-going reference book for all the fundamentals.
Divided into three sections, this book provides everything you need to know to startprogramming in Delphi 6.
The idea behind the Nitty Gritty seriesWhen you are programming, you also usually read a great deal. The fact is that the various programming languages have reached performance levels that make it almost impossible to get an overview of all the functions offered by a programming environment. This is why there are so many and varied reference books that attempt to provide a lot of information in an understandable way. Unfortunately, the really good reference books from the reputable publishing houses are usually weighty tomes that will just clutter up your desk. The slimmer books are easier to handle but often do not contain the information you are actually looking for. It is just when you are learning something new that you could really do with a book that has sections that contain reference material about the programming language, and sections that show you how to create functioning programs quickly, and how to make best use of many of the options available in a programming environment. The Nitty Gritty series of books is based on this idea. These books are interesting not only for people who are learning a programming language, because they contain a lot of basic facts, but also for people who already know how to use other programming languages and want to extend their knowledge. This is the next chapter of the Delphi story, which began with Borland and Delphi 5 and continued with Delphi 6. Although the software has become more expensive, the Personal Edition (previously the Delphi Standard Edition) still has almost all the same features as Version 5. I am rather disappointed by this. It would have been possible to increase the price slightly and introduce a few of the new features in return. Sadly, this didn’t happen. There isn’t much point in writing a book about the Personal Edition (it really can’t do a great deal), and there is nowhere near enough space for the features of the Enterprise Edition (I could write 1000 pages in this format and would still only scratch the surface), so I have restricted myself mainly to the options offered by the Professional Edition. In my last book, I mentioned that this version is the very least you should purchase, and I am still convinced of this. It really is a wise investment because Delphi 6 has become even better than I dreamed it could. The critics among you will say that it took long enough to appear. But you will have a product that is well worth the money and lives up to its reputation. It is a professional development tool that gives you all the freedom and possibilities of programming under Windows and (if you also have Kylix) Linux. I wish you every success and hope that this book will be of some use.
Style conventionsI have tried to design this book so that you can easily see what it contains. The following styles and ways of emphasizing text are used in this book:
‘ Menu items and directories are shown in Small capital letters.
‘ Source code and descriptors associated with the source code are shown in the body of the text in Courier font. Reserved words are shown in bold text.
‘ Keys and shortcuts are shown as if they were keys on your keyboard, e.g. S + c means that you must press the S and c keys one after the other, then release them at the same time.
Tip This icon is used to indicate tips and typical programming errors.This is the second Nitty Gritty paperback about Delphi. The first Nitty Gritty book was also the very first book I wrote, and when I handed over the manuscript I still had a few doubts about my abilities as an author. Luckily for me (and all the readers), my worries were groundless. Numerous letters and other communications have reassured myself and my editor, Christina Gibbs, that we had found a successful concept and selected the right authors for all the books, and that the books themselves were also very useful. You could say it was a real success. So, I would like to thank everyone who has purchased and read this book, despite the delay in its appearance. I must thank the editing department at Addison-Wesley Germany, especially the editors Christina Gibbs and Christiane Auf. Christina started the book and then the support tasks passed on to Christiane. At this point, I would like to give them both my warmest thanks for all their support and hope that we will be able to work together again on the next Nitty Gritty edition. Another person who deserves my thanks is my former tutor Klaus Kappler, who is now a good friend of mine. He supported my decision to leave my former job and to break into completely new areas in my professional life. I am sure that this was a very good decision. So thank you very much. If you are ever in Munich, I’ll buy you a coffee. My last thank you goes to Anders Ohlsson from Borland who was kind enough to allow me to use his code in this book. You will see his code for a cgi counter in the internet chapter of this book. The last thing for me to say is that I hope that you enjoy the book.Frank EllerJune, 2002
