The COM to COM+ Programming Primer (Prentice Hall Series on Microsoft Technologies) (Paperback)

COM and COM+ are the foundation of virtually every new technology Microsoft is developing, and COM+ is an essential feature of Microsoft's Win 32 platform (and, therefore, a cornerstone of Windows 2000). COM and COM+ have a reputation for being extremely difficult to learn -- but it doesn't have to be that way. The COM and COM+ Programming Primerteaches both technologies from scratch-- step-by-step, using on-target analogies, simple example programs, and an "inside-out" teaching method that makes sure readers really understand before introducing shortcuts such as Microsoft's wizards. Alan Gordon starts with crystal-clear definitions of every Microsoft technology related to COM, including ActiveX, OLE, DCOM, DNA, and COM+. Understand the fundamental classes, objects, and interfaces associated with COM. Next, build your first COM object, and simplify it using ATL 3.0 and Visual C++ Native COM support. In Section II, dig deeper into COM: create an out-of-process server; understand Automation; work with COM callbacks and connectable objects; master threading; and review the additional distributed development features Microsoft introduced with DCOM. Next, understand the key distributed technologies that set the stage for COM+: Windows DNA, the Microsoft Transaction Server, and MSMQ. Finally, in four practical, hands-on chapters, you'll start working with COM+ in the Windows 2000 environment: creating objects, working with threading, even building full-fledged n-tier applications.

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, you'll follow an experienced instructor and programmer/developer through COM+ and COM code from the "inside out," so you understand its deep structure. You'll 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 you'll be creating usable applications in record time.

With Alan Gordon's straightforward explanations and practical use of standard tools, you'll get the in-depth knowledge you need to create applications that leverage COM+ and all the technologies in the Windows DNA 2000.
