Well there are two different ways to do it that I know of. The easiest would
be the xmlhttp objects available in IE5+ and Mozilla. Sending url
parameters, and getting back your data in a parseable format. I haven't done
this but in theory it is very easy. Some code...
try {
// for Mozilla
req = new XMLHttpRequest();
req.overrideMimeType("text/xml");
} catch (e) {
// for IE5+
req = new ActiveXObject("Msxml2.XMLHTTP");
}
req.open("GET", "page.html",false);
req.send(null);
If NS4 is a requirement hidden ilayers are the only way to go. In which
case, you might as well use the hidden iframe method in IE/Moz. In this case
you would change the src of the ilayer/iframe, and in the page in the
invisible frame you would grab the data you want from the database based on
the url parameters, and have functions in the hidden object that basically
pass the data to functions in the parent page that do the visual stuff like
filling in form fields.
I have a site up that is doing this now for a phone number lookup, but it
requires a login. Shoot me an email and I can send you a demo u/p.

Subject: Calling server code without reloading
> Lets say I have a form field on a page. When I type in it, I want what I
have typed to be sent to the server and something done to it. THe result of
that something will come back to me and be loaded into a different form
field. This should be done without reloading the page.
> Normally, I'd do this with a hidden frame and some javascript. I've been
asked to do it some other way using layers, objects or other stuff. I'm
researching it but I might as well ask if anyone here has heard of something
in this area.
