I think I am asking the right newsgroup. If not maybe someone could
tell me where to ask this "beginner" question.

I want to click on an image (.jpg) that launches a Microsoft window
(cmd.exe or command.com) which executes some .exe, e.g googleearth.exe.
I know this is simple
for most of you but I am just starting XHTML. I think it begins with

<html>
<body>
<p>
An image as a hyperlink:

<a "???">

<!-- start Google Earth by clicking image -->

<img border="0"
src="ge.jpg"
width="32" height="32"/>
</a>
</p>
</body>
</html>

Thank you.

You can't start applications directly. What you need to do is provide
the user with a document that opens the application indirectly.

For example, to launch Google Earth, your link should point to a KML
file. If Google Earth is installed and the user's browser is set up
correctly, the KML file will be passed to Google Earth by the browser.

It's not possible. If it were possible, that would be a major bug and
would need to be fixed immediately in that browser.

Maybe your page just starts Google earth and is safe. How would you
distinguish this from my page, which is Evil and starts "format c:/"
instead? You see the problem, for why web browsers _can't_be_
permitted to escalate privileges from merely display documents to
starting programs.

There are ways around this. One way would be to embed an executable
ActiveX control on the page and allow that to run with serious
privileges. Then how do you prove the ActiveX control itself is safe
and trustworthy? There's still no widespread consensus on how to do
this reliably and flexibly which is why ActiveX hasn't ever taken the
web by storm.

I'd like to be able to run an executable via a link in a browser on our
intranet. Do you have any leads on where I might find an activex
control such as you mention?

Thanks, Peter

If you're after Google Earth, then the best way is probably a link to a
.kmz file. You can get users to set permissions on .kmz files to be
quite generous and to open GE automatically. There'll be a certain
amount of per-user config to do for each browser though.
