The Directory Opus scripting interface is built around ActiveX. The advantage of this is that Opus scripting is language neutral - you can use any ActiveX scripting language you have installed on your machine. Windows ships with VBScript and JScript interpreters, and you can add additional languages from third-party providers (e.g. Perlscript, Python, etc).

The scripting interface is presented as a number of Objects and Events.

  • Objects are created by a script, or provided to a script by Opus, and have defined methods and properties that allow you to interact with Opus.
  • Events are functions provided by a script, that Opus will invoke under certain conditions. For example, the OnBeforeFolderChange event is fired before the folder is changed in a Lister.
