Implement client/server applications with ease with this example-oriented approach to the details and implementation of COM technology in network applications.
If there was ever a subject that lent itself to examples, COM is it! None of the APIs, configuration files, classes, wizards, or helper applications of COM can stand alone 3/4 you need an example of how to use them together in order to know how to do anything. This book will do for COM what the author's recent MFC books have done to teach that technology. You get a quick but thorough overview of COM technology, and dozens of real-life examples that can be used to accomplish virtually all of the requirements of a COM project.
COM Basics are addressed succinctly in the first three chapters. You will learn how to:
- Use the COM API to create a COM object;
- Prepare your DLL or EXE so the COM API can access the class objects inside;
- Exchange data with your COM objects by passing arguments in any function call, or implementing automatic serialization and reconstruction of your data through a network port;
- Address other details of COM implementation including deriving the functionality of another COM object in your own, and security matters;
- Implement COM+ and Microsoft Transaction Server (MTS) to permit massive scaling.
COM Examples provided in this book will enable you to implement this client server standard with a minimum of effort 3/4 whether you are a COM novice or an 'old hand'. They demonstrate how to:
- Create and access COM objects using an entire range of COM techniques including C++, MFC, ATL, Visual Basic, and Visual J++;
- Use COM to automatically send data between your client and the COM server;
- Write a COM+ object that will engage the event server provided by Windows 2000;
- Use Microsoft's the Active Data Objects (ADO) library to access a database.
COM Project Building Blocks are provided on downloadable files along with a special utility, the author's own Sample Wizard, that will interactively insert the examples into your applications.
