Learn how to build 3-tiered, thin-client application with COM+ and the Windows DNA 2000 * Extensive coverage of COM+ * Step-by-step instructions show you how to build Components that use COM+ Services: Fine-grained security, transactions, synchronization, queued components, and loosely coupled events * Learn how to integrate all the technologies in the Windows DNA 2000: COM+, ASP, IIS, SQL Server, OLEDB, ADO, and XML * Starts from first principles-no need to understand COM already * Build on your skill base with Visual C++? and Visual Basic? COM+ is the second generation of COM. It includes new features that make COM easier to use and simplifies the development of distributed, enterprise-class applications. COM+ builds on the distributed infrastructure provided by DCOM and MTS, and it represents the evolution of COM from a desktop, application integration technology to a distributed, application development infrastructure. In The COM and COM+ Programming Primer, youll follow an experienced instructor and programmer/developer through COM+ and COM code from the "inside out," so you understand its deep structure. Youll build simple objects from scratch to gain a thorough familiarity with the underlying concepts. Your existing skills in Visual Basic and Visual C++ will help you master COM and COM+ so youll be creating usable applications in record time. With Alan Gordons straightforward explanations and practical use of standard tools, youll get the in-depth knowledge you need to create applications that leverage COM+ and all the technologies in the Windows DNA 2000.
