The ScriptConfig object is very simple to use, and I'd recommend using it directly, at least at first. Otherwise you have to understand how ConfigHelper works on top of how the underlying object works.
A couple of simple examples of using ScriptConfig can be found here:
-
Auto-load Thumbnails only in specific folders
VBScript. Configurable list of folders, and a configurable boolean flag. -
Columns: Maximum and Average File Size
JScript. Configurable minimum file size.
