Query: Good, concise intro, but the rest is fluff

The first 100 pages provides a good concise overview of COM programming. It is well written and to the point. However, the remaining section (250 pages) of examples was disappointing. The examples were shells only and had only a summary explanation of each. The same content was copied over and over in all the examples. For example, the "How to register the DLL" explaination, which took almost a page, was copied verbatim in the other examples. Instead of building on a concept, it was simply repeated. 90% of the examples were MFC generated code. It seemed to be more an attempt to fatten up the book rather than to provide content. In short, I think one would be better off with another book that can provide more in-depth examples that one can learn from. Not just the same MFC code again and again.
