The COM specifications for applications using Active Scripting are not difficult to understand, and Python has additional helpers that reduce this to a small amount of code.

The sample application exposes an Active Scripting object model. It loads script code from a text file and executes it using any Active Scripting-supported language: two more examples will demonstrate VBScript and Python. The object model the application exposes is simple; there’s a single Application object supporting a single method Echo, which displays a message box.

These are the steps:
