The one book you need to master Windows 2000 COM+ and DNA development: combines expert high-level theory with practical hands-on programming techniques that go far beyond what you'll find in most COM/DCOM books! Robert J. Oberg starts by introducing COM+ and Microsoft's Distributed interNet Applications architecture: the forest and the trees. Learn how to build a testbed you can use for all your COM+/DNA application development. Refresh yourself on the key COM and DCOM concepts that still underlie COM+ development, including multithreading, automation, error processing and debugging. Next, master the key COM+ techniques associated with advanced multi-tier development -- hands-on, through building your own application. You'll find detailed coverage of COM+ security in Windows 2000 environments; a "survival guide" of key database programming techniques; practical information for using the In-Memory Database and Microsoft Message Queue; and much more. The book goes far beyond most COM/DCOM/COM+ books, with sophisticated coverage of ATL, multithreading, clustering, monikers, the Windows Registry, and much more!
