Expert COM programmer Richard Grimes shares his knowledge of Microsoft Transaction Server (MTS) and ATL in
Professional Visual C++ 6 MTS Programming. Like some of his other titles (
ATL COM Programmer's Reference and
Beginning ATL 3 COM Programming), this book combines his in-depth knowledge of COM with a programmer's eye for detail in getting the most out of your COM objects. Written for the expert C++ programmer with some previous knowledge of COM and ATL, this book fills a useful niche for letting you create optimized server objects with the best potential for scalability on the Microsoft server platform.
The book jumps right in with a discussion of what happens when you make COM calls with an in-depth discussion of COM interception. The author shows that you can emulate some of the powers of MTS yourself. (Simply put, by managing resources and transactions for you, MTS-enabled COM objects can be more scalable and robust.) Short code excerpts show off programming with COM and MTS together. The author also demonstrates a method to tweak the wizard-generated code in Visual C++, enabling you to write more powerful MTS-aware ATL components.
You can also enable your ATL-based objects to access corporate data with ADO using the introduction provided here. The last section on the new COM+ available in Windows 2000 illuminates the capabilities of MTS that will soon be integrated into the COM+ infrastructure itself. The author provides a detailed tour here of what COM+ means for the future.
In all, Professional Visual C++ 6 MTS Programming is a book for experts who want to see what MTS (and COM+) do under the hood. If you need to squeeze more performance out of your MTS-enabled ATL components, take a look at this technically savvy book. --Richard Dragan
