Ha, great minds think alike VVA!! I went that route too, but newer versions of Internet Explorer (IE) detect the abuse of their clipboard and intercept with a "Do you want this web page to access your clip board?" dialog prompt. Even worse, said dialog may be hidden behind the AutoCAD session, so it may appear AutoCAD has gone 404 (minimize all windows and poof, there the bugger is). So in my mind it's
an interesting but completely unusable / unreliable technique, and why I opted not to post it. I'm guessing the
technet article is a couple years old and predates versions of IE which attempt to be more immune to hostiles.
This is my experience anyway, coders beware; cheers.
