ASP and Real-Time Data

[crashcup]

Can you shed light on "how" one would view a database in Internet Explorer... and have the data shown in the browser update when the database information changes.

I understand how to use Javascript to force a refresh.
I'd like to know "if and how" the data can update in the browser automatically without a browser refresh.

If no example/information can be presented here, what language/tools would one use to perform such a task.
I think ASP for sure, maybe with VB.. but "how would the browser know" if the data changed?

Where can more information be obtained on how this technology works?

ASP can do it (but only with IE I think) using a technology called Remote Scripting.

For more information on it you can google it or check out:

That's really the part specific to refreshing data without a page reload. As for diplaying info from a database as a table in ASP it's a fairly basic/common thing that is covered in many articles. http://www.google.com/search?q=displ...base+table+asp

Finally, if you know javascript and asp well you can have a invisible page refreshing regularly in an iframe, which uses javascript and dhtml to update the information on the parent page. I've done it before, and it works well, but it's not trivial to put together.

Also, ASP.NET has the ability to do it using Script Callbacks. For an overview of that go to:
