Microsoft’s Windows DNA technology framework is built upon Microsoft COM+ (Component Object Model). COM+ is the basic glue that is able to transparently connect different islands of code, for example, the different tiers in a multi-tier software system. Since COM/COM+ is available in every Windows-based operating system, it is the infrastructure of choice for building distributed component-based applications in a pure Win32 environment. The goal of this tutorial is to provide a detailed overview of Microsoft COM/COM+ for C++ developers. The tutorial will be presented in three parts. The first part covers the architecture behind Microsoft COM/COM+. The second part illustrates all constituents of COM using C++ examples. The last part covers advanced services such as MSMQ or MTS. Attendees will learn how to leverage COM/COM+ for their own applications. Presentation Format: Lecture with small example demonstrations. Attendee Background: Attendees should be familiar with object-orientation and C++. They should also have some experience in programming Win32 applications. Michael Stal is head of the Distributed Object and Component Computing group at Siemens Corporate Technology. He is co-author of the book “Pattern-Oriented-Software Architecture - A System of Patterns” as well as of “POSA2- Patterns for Distributed and Concurrent Objects” (to appear at OOPSLA 2000). Michael represents Siemens at the OMG. He is editor-in-chief of the German magazine Java Spektrum, and president of the International Java Club.
