Prevent browser close

[Velvet]

I am developing for a kiosk system. IE is loaded on this sytem and we want
to make sure that there is a browser open to our website location at all
times. So when the user closes the browser we want to either stop the close
and send the user back to the default page, or we want to detect to make
sure there isn't anyother browser open and if not open a new one to replace
the one that was closed.

So does anyone have any code samples that would help out on one or more
parts of this?

Thanks in advance!
Velvet

See Michael's response...

How could you prevent someone from popping Task Manager and killing the
task...?

There really is no 100% reliable way of doing this...

The network cable will not be accessible so I don't see that as an issue.

About the service. I've not written a service application before. Do you
know of any tutorials which would point me in the right direction?

Also, isn't there something that I could do in the window.onclose event that
could prevent the browser from closing in the first place? I haven't found
anything in my searches, but I seem to remember that it was possible.

Thanks!

We are locking down all other operations through group policy's.

Keep the idea's coming pelase...

Hello Velvet,

Start from here http://pinvoke.net/default.aspx/user32/EnumWindows.html

I'd recommed to unload shell at all (explorer), and apply strick group policies,
so users have no access to any windows applications except your browser.
This is topic for windows newsgroups

Problem Solved! It turns out that we can disable browesr close with in the
group policies in Windows itself! YAY! No extra last minute coding
required!

Thanks all!
