By showing you why Distributed COM works as it does, Don Box enables you to apply the model creatively and effectively to everyday programming problems. In addition, the book offers a thorough explanation of COMis basic vocabulary, provides a complete Distributed COM application to illustrate programming techniques, and includes the authoris tested library of COM utility code. In Effective COM , the authors, Don Box, Keith Brown, Tim Ewald, and Chris Sells, offer 50 concrete guidelines for creating COM based applications that are more efficient, robust, and maintainable. Drawn from the authors' extensive practical experience working with and teaching COM, these rules of thumb, pitfalls to avoid, and experience-based pointers will enable you to become a more productive and successful COM programmer. Throughout this book, the issues unique to the MTS programming model are addressed in detail.
Dual interfaces are a hack.
Don't rely on JIT activation for scalability and much more invaluable advice. For each guideline, the authors present a succinct summary of the challenge at hand, extensive discussion of their rationale for the advice, and many compilable code examples. Readers will gain a deeper understanding of COM concepts, capabilities, and drawbacks, and the know-how to employ COM effectively for high quality distributed application development.
