Obtaining Client-Specific Information with a Web Application, Page 2
Creating an ActiveX Object
ActiveX objects for ascertaining client information include WScript.Network and WScript.Shell. WScript.Network can be used to determine the active user, for example, and WScript.Shell can be used to query information like the path to the MyDocuments folder. For a complete reference for these ActiveX libraries refer to the MSDN help documentation.
The end of the listing contains a statement that starts
with var jsonObject. Programmers used to create objects by
Object() and referring to the
desired properties. The revised syntax above is part of JSON
lightweight data-interchange format that is a subset of
readable form, and the technology plays in the same space as
XML. The statement above creates an object with two
properties: UserName and MyDocuments.
