The one sentence I most want to say about this book is that it has come too late. Since the first release of COM in 1993, COM itself has undergone significant changes, but its fundamental ideas and structure have remained relatively stable, which precisely demonstrates the charm of COM's concepts. Despite this, due to the mysterious nature of COM, not everyone can easily understand the ideas and appeal of COM. Fortunately, we now have this book, which will clearly explain everything to you.
This book is undoubtedly the most prestigious work in the field of COM literature. Two years ago, I read chapters three and five of this book on the MSDN Library, and at the time, I found the content very disorganized, so I didn't quite understand why it was so famous. Later, after taking the time to read reviews from readers and experts on amazon.com, I realized how important this book is for enhancing one's understanding of COM. This translation process gave me the opportunity to carefully read every detail of the book. Even though I am reading it three years after the original publication, its contents are still highly valuable as a reference today.
