Because this hidden input field should have 'value=...' returned by the
document.write <resolution> :)))

Why do you need to create them this way? Why not just type them as
regular HTML? No-one will see them coz they're hidden :-)

If you want to create a session var, you'll have to POST or GET this data
to an asp page which then creates the session var.
Alternatively, you could use js to write a cookie and then use
request.cookies to get the info in asp. Of course you'll have a problem
with your first page - until the js runs, the server won't know the screen
resolution, so what will you do?

I want help in order to combine a client side script and a server side
'decision'...
What I want is creating HTML based on user screen resolution. I will assume
only 800x600 and 1024x768.
So, is it possible to use something like...
<SCRIPT LANGUAGE="JavaScript">
document.write(screen.width," x ",screen.height);
</SCRIPT>
to create an ASP Session Variable?
I just want to use this variable to offer a suitable design to users
Any idea?

That's it!!!
No problema about GET and POST, but I didn't know how to use js to create
it...
I understand I can use normal HTML
<form method=POST name=myform action=mypage.asp>
<input type=hidden name=scr_height> <!-- no value clause -->
</form>
Where do I must write the following javascript code?
<script language'javascript'>
document.myform.scr_height.value = screen.height;
</script>
Thank you very much, PHIL, and I hope it's about to finish :)))

Right, POST just means you have a form on an HTML page with method="POST"
and action="yourasppage.asp". In that form you can put a few <input
type="hidden"> fields, say named (and id'ed) screenwidth and
screenheight. Then in js you would do something like:
document.formname.screenwidth.value = screen.width;
document.formname.screenheight.value = screen.height;
document.formname.submit();
...
in yourasppage.asp you would have:
Session("ScreenWidth") = Request.Form("screenwidth")
Session("ScreenHeight") = Request.Form("screenheight")
then you have your session vars.
GET just means the form method="GET" and the values are appended to the
URL, so you have 2 choices:
1. as above for HTML/JS form and code, but in asp you use
Request.QueryString("screenwidth") instead of Request.Form("...
2. forget the HTML form entirely and do some JS like:
var sHref="yourasppage.asp?screenwidth=";
sHref+=screen.width; // you may have to parseInt this value
sHref+="&screenheight=";
sHref+=screen.height;
window.location.href=sHref;
Then in asp you use Request.QueryString again...
OK?

redirecting to itself. Is it a good idea?
About POST and GET, I just wonder "how" :)) I'm not bad in ASP, but I
really
must be better than I am in JavaScript.
I appreciate your help...

How about putting the js in the onload of the <body>? Or sticking it
right at the end of the html page? Either should work.
