I'm building an ASP page that has a lot of text and graphics.
There is a calculation facility on the page. The user enters several
numbers in a form and presses a button to see the calculated answer.
The problem is this: when the user presses the Calculate button, the
whole page is reloaded and, on a large page, this is very noticeable.
Is there any way that I can get the calculation done and the result
displayed without reloading the whole page?
A simplified version of the page "calctest.asp" is shown below.

If the calculation is simple and you do not care if the user sees the
algorithm, do the calculation in JavaScript and do not go back to the
server.

Thanks, but I don't want the user to know how the calculation works.
As for JavaScript, not everyone uses it.

OK, you can hide the algorithm with an include file. As for JavaScript,
only IE understands VBscript. All browsers understand JavaScript. All
client side scripting requires that you learn JavaScript. Server side
scripting can be VBscript. Good luck.

Thanks for the input. When I said that not everyone uses JavaScript, I
meant that some people, including me, have it disabled on their
machine for security purposes.
The reason I want to handle the whole process server side is so that
any client configuration will see the same website.
BTW, include files don't hide your client side code from the really
determined. If their computer can read it, they can read it.

You can do this with concealed iframes, but you will need clientside
code to realize this.
Thanks, but I don't want any client side code. The whole process must
run on the server.
That is what I said. The proces runs on the server, but either you load a
new page everuy time or you use clientside code to load the output in a
concealed iframe and then using it on your initial page.
That is your choice
Some users disable JavaScript
You mean, I think, some users disable clientside code, this can be
javascript and [in IE] vbscript, just as serverside code can be in
javascript, vbscript, and many more.
and, besides, I don't want to make the code visible.
The code of your secret algorithm is not accessable, as it stays
serverside. only the code to enter the result on the clients screen
without a total refresh is clientside.
That leaves me with the original problem: how do I refresh a box on
the page to show a calculated result without having to re-send the
whole page?
Impossible without clientside scripting.

Iframes are limited. Like other frames, they're not very search engine
friendly. I'm also left with the client side code problem. You can't
depend on the client machine to run your code properly. That leaves me with the original problem: how do I refresh a box on
the page to show a calculated result without having to re-send the
whole page?
Impossible without clientside scripting.
I thought that, but I was hoping somebody knew better.
Thanks for your thoughts.
Have you tried using Remote Scripting? The premise of this technology is
that it will do calculations without reloading the whole page. It's
tricky...you'll have to read the documentation on it carefully, (and it
doesn't work in Netscape) but, if you have a specific audience that uses
only IE it can be your answer.
Good luck,
Linda

Another option is xmlhttp. I have a demo for this at http://tinyurl.com/5luf. Scroll down to the dynamic listbox example.
