I don't mean ActiveX controls embedded in a web page.
I mean that each gizmo in the DOM - every Element, Form, Attribute,
etc, is itself an Automation object. (A COM, OLE, ActiveX object, with
an IUnknown interface, a dual IDispatch interface, etc, just like a
high-end ActiveX Object!)
You don't need to know that, but you do need to know how to query such
an object for its "Intellisense". A real Ruby object responds to
.public_methods to generate a list of members, but a Ruby OLE object
only responds to OLE messages by throwing and catching its "unknown
method" error. So .public_methods can't return all the methods that
_aren't_ there!
Call this on any DOM object:
def docOle(thing)
puts thing.ole_methods.collect{|m| m.name }.sort()
end
It barfs out a sorted list of all your object's members (using the
secret IDispatch member query system).
(The other way to get good Intellisense is write a scratch project in
Visual Basic, and use that smarmy editor's introspection and code
browsing features. Then port what you learn back to Ruby!;)
