Technical overview

In Microsoft Windows operating systems, the Microsoft COM technology lets software components communicate with other software components. You can use Microsoft COM technology to create reusable software components. You can also develop applications by linking these components together and take advantage of Windows services.

You can develop Microsoft COM objects by using different programming languages. For example, you can use object-oriented languages, such as C++ or C#.

Note You can use Active Template Library (ATL) in Visual C++ to simplify the implementation of COM objects.

The sample projects that are provided in this download package show how you can expose properties, methods, and events in Microsoft COM technology.

Note For more information about how to use this sample, see the Readme.txt file that is included in the download package.
