A must-buy book for intermediate-level developers
on February 17, 2000
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.
