Essential COMWritten by a leading COM authority, this unique book reveals the essence of COM, helping developers to truly understand the why, not just the how, of COM. Understanding the motivation for the design of COM and its distributed aspects is critical for developers who wish to go beyond simplistic applications of COM and become truly effective COM programmers. As the COM programming model continues to evolve, such insight also becomes essential to remaining current with extensions, such as Microsoft Transaction Server and COM+. By showing you why Distributed COM works as it does, Don Box enables you to apply the model creatively and effectively to everyday programming problems. |
