Thank you very much. I've never used IDispath and interfaces in general,

there any way you can point me to a sample code?

You can get the IDispatch interface of the script engine by getting the
"script" property of the MSHTML document object, and call
IDispatch::GetIDsOfNames to find if a property/method exists. The

properties

of the script object are the global vars, and the methods are global
functions.

Guys,

An unusual request -- is there any way to determine if an
object/property/method is a valid DHTML JScript object? Something like

this:

Code:

LPCTSTR pObjectName = "document";
if(<API_to_check>(pObjectName))
{
AfxMessageBox("Valid object");
}
