Summary: DCOM
Review: I find the book usefull for writing COM objects with delphi. This the only book I find at amazon writing COM objects with delphi. But I have a question about writing DCOM objects. At page 299 under the title "Creating DCOM client". The author says us to import DCOMServer.tlb type library. But I cannot find this on neither my machineor anywhere else. Is it a standart Type library? It will be very good if you ilimunate us for this. Thanks You.

Summary: Not worth buying
Review: I think this book is not worth buying, because there are too many features that was just left off by the author, using always the same excuse: "Well, this feature is not commonly used, so I won't disscuss it any further in this book". Besides that, it gives you a big averall coverage of COM. If you want to go to the inners of COM, this book is not for you. It was not for me.

Review: Just a quick note to say this is a super book. A great, lucid introduction to COM. The section on Istreams and structured files was super useful. If you are ever going to use COM at all, this book is a must

Summary: COM Basics explained nicely....BUT.....Some Major Typos
Review: This book has already added several nuclear warheads to my programming arsenal. It explained many concepts I have struggled with in a very explicit manner. There is a severe problem with this book however. I have already found errors in the code examples that have hindered my learning. The top code example on page 24, and on page 26 are good examples. On page 24, TObject was not typecasted as a TFormattedInteger and thus could not be casted "AS" an IFormattedNumber. It generated the compiler error described on page 25 even though I had a GUID declared in the IFormattedNumber interface. On page 26, MyInteger is incorrectly declared as a IFormattedInteger, even though no such Interface is declared in any of his other examples. I do not want to belittle this excellent book however. I just simply cannot give a book with these types of errors 5 stars when the writer obviously did not test every example he presents. It is definately still worth buying. I even suggest buying this in tandem with "Delphi4 Unleashed" by Charley Calvert because that book explains COM/Interfaces a little differently and can help you get the concepts faster by filling in some of the gaps. Hope this helps. Curtis S. Lead Programmer/Analyst Insurance Technologies Corp.

Summary: "The Ultimate Guide for a Newbie to Com Programming"
Review: This book is detailed to say the least. It encompasses topics from native Delphi interfaces to creating Shell extensions through COM. All chapters contains numerous detailed examples of high quality. For anyone that wish to create COM-based solutions with Delphi, this book is required reading.

Summary: Excelent book!
Review: Um livro importantíssimo para aqueles que querem utilizar todas as potencialidades da programação baseada em COM/DCOM. A introdução ao ADO é bem feita, e com um exemplo muito prático e elucidativo. Apesar dos poucos erros em alguns códigos, o livro é muito bem escrito, sintético e didático. Eu o recomendo. Programadores em Delphi do Brasil, leiam este livro!

Summary: A must-buy book for intermediate-level developers
Review: Until now the only decent Delphi reference on COM has been the two chapters by John Lam in Marco Cantu's "Delphi Developer's Handbook". This new book presents 500 pages of well written, focused coverage of the practicalities of Delphi's COM implementation. It is ideal for those with moderate Delphi skills who want to come up to speed quickly in writing ActiveX Control or Form solutions, or who want a good explanation of the usage of interfaces, variants, connection points, automation or DCOM. Although it goes into depth in a couple of places - structured storage and property sets in particular - readers will still need to look to people like Binh Ly for advanced discussion of threading models and so forth. I was hoping to find detailed discussion of the internal workings of DAX, TOleContainer and the TComObject/Factory descendants, but most of the code in the book focuses on *using* the VCL framework rather than on its design and the various bugs and gotchas it works around. Those with C++ COM/OLE experience looking for Delphi solutions (eg those rolling their own OLE DB providers, windowless ActiveX controls or Active Document servers) may be disappointed: it's not "Inside ATL" for the VCL. However I think the majority of Delphi developers - who don't have time to read Brockschmidt or Box but just want tools and solutions that work - will find the book a great time-saver and reference. COM newbies wanting Delphi tutorials need look no further. It's certainly an excellent contribution to the Delphi literature. I'll be buying a second copy for the office, but it left me thirsty for more.
