~~Title: Scripting Reference ~~
<pageheader/>

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//.

  * //[[~scripting_objects|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. 
  * //[[~scripting_events|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.
