Designing Solutions With Com+ Technologies - Tapa blanda

Many developers encounter COM+ issues that have already been worked through by other developers. This book documents these common COM+ design and implementation issues, gives you proven ways of solving them, and presents practical technical advice and information to help you avoid COM+ pitfalls. It offers a wealth of design patterns, best practices for implementation, explanations of how the latest COM+ services work, plus in-depth analyses of performance trade-offs between competing COM+ solutions-all so that you can profit from the experience of those who have been successful in the COM+ development environment in enterprise projects across various industries. It also gives you extensive code samples in text and on the companion CD-ROM in Microsoft Visual C++ and Visual Basic. Packed with problem-solving insights, this book covers these topics: COM+ fundamentals: Handling errors properly to enhance the maintainability of your software; employing smart pointers to improve robustness; understanding string details in C++ and international development; making the most of COM+ concurrency; learning to create, call, and implement COM+ objects in interoperable development environments. Architectural patterns and solutions: Taking advantage of the Active Template Library (ATL) to achieve reuse through multiple inheritance; building efficient cross-platform data-transformation services; understanding marshal-by-value implementations in C++ and Visual Basic; mastering COM+ reference-cycle management; using generic programming and the Standard Template Library (STL) in the COM+ realm. COM+ in the enterprise: Architecting business systems with a COM+ four-tier business-object application pattern; designing solutions with the Simple Object Access Protocol (SOAP); building massively scalable systems with Microsoft Transaction Server (MTS); understanding data access in the COM+ age.

A thorough working knowledge of the Microsoft "RM" Component Object Model (COM) and COM+ technologies is a prerequisite for effective design and implementation in today's networked Microsoft Windows "RM" operating environment. But many development teams, during the design and implementation phases of their projects, encounter generic COM+ issues that have already been worked through by other developers. COM+ Software Architecture documents these issues and presents ways of solving them that have proven successful in past projects. This book provides practical solutions to practical problems on more than one level. Some chapters qualify as design pattern catalogues, others offer implementation best practices, and others analyze performance trade-offs between competing solutions. All offer the kind of focused COM+ technical advice and information that can help developers avoid design and implementation pitfalls by learning from those who have already been successful in the COM+ development environment.
