I don't see why this node has 3 keep votes, but I'll answer your question anyhow: No. It's not possible with perl, but theoretically you could do it with an ActiveX control. I'm not getting into detail about it, read it up on your own. Note that it's a Micro$oft thing, so it's audience is limited. My best answer: don't do it. Let the user download it and execute it themselves. No extra work for you, the amount of work an internet user expects to have to do, and it keeps the internet the way it was meant to be. Dont Do It. Period.
