For all those who want to learn how to design scripts for XWidget:
XWidget runs the Microsoft Script Interpreter, which works on top of WSH. It thus supports any scripting language WSH can understand. Support for
Microsoft JScript, a Microsoft specific dialect of JavaScript, and VBScript comes out-of-the-box. However, you can install support for other languages like Python,Ruby or Perl.
Wikibook JavaScriptA nice resource for all sorts of JavaScript, make sure to read the Core First, other topics deal with browser programming,AJAX etc and are irrelevant to XWidget.
