live data??? possible in .net???

is it possible to display 'live' data in .net via a web page? by live data i mean data that is changing dynamically, say once a second

i am guessing i need to use java to go this route because MS has no support for it. however, if it is possible to do with .net, i'd be very interested

my thought is to have some kind of socket connection to the server where data is refreshed at a high rate of at least 1 time a second, possibly more (we've had the need for upwards of 10 times a second in the past)

we have windows forms applications with real-time data that we want to web-enable. static data isn't of much use, we need it changing actively

thank you for any suggestions

you'll have to reload the page or use some sort of clientside component to
refresh

Curt is right. Asp.net is just the same as most other dynamic technologies
in that all it does is generate html on the fly and send it to a browser.
Just like JSP, ASP, PHP or whatever.

You can either refresh the page or use an applet.

You might also look for something called "server push" on google. I heard
there might have been a way to do what you were asking in IE 5.5+ but I'm
not at all sure about it.

How about using an embedded .Net Windows Form?

Yes, but not using ASP.NET alone.

Not quite Java, the solution need not be so complex.

Look up using the XMLHTTP object (for internet explorer) and it's
other-browser versions. With a bit of DOM-based scripting and some help
from remotely loaded XML, you can basically keep a page up-to-date
without having to postback every 10 seconds.

If you're after total ubiquity - that is, you want the data to be
available on the widest range of platforms and browsers - then consider
using XML with Flash, or Java as you say.
