ASP & browser height

I was wondering if there is a way to determine the browser height in ASP.

I know that in Javascript there is an Screen Object, but this object cannot be accessed using ASP.

So I was wondering if there is a way to get the height and width of the users browser in ASP OR call an external JS function that has the coordinates and pass them onto the ASP section.

ASP is server side, so it does not really have access to the browser object. You coul duse 3rd party components or use JavaScript to pass the height/width as you mentioned.

Yeah, I think that will work great. But, I'm not exactly sure how to do that?

You cant call a function like this:

Code:

<SCRIPT> function test() { return someword } </SCRIPT> <%= test() %>

How would you go about passing in a variable?

Lets say you have three pages, one which detects the height/width and pass the info to the 2nd page which stores the values in session and finally the third which performs something after retriving those value. I will use pseducode, if you need full asp code then let me know.

page 1

inc_store.asp
VB Code:
```
<%
dim URL
url=request.querystring("URL")
 
session("Height")=request.querystirng("Height")
Session("Width")=request.querystring("Width")
 
 
%>
```
page 2

inc_detect.asp

Code:

<html> <body> <script language=javascript> var width; var height; width = screen.availWidth; height = screen.availHeight; document.location.href="inc_store.asp?Height=" + height + & "&Width=" + width </script> </body> </html>

page 3

demo.asp
VB Code:
```
<%
 
if session("Width") =whatever then
   do something
else
   do something else
end if
%>
```
You could use cookie instead of session, it's up to you, you could also use iclude file in each of your asp page to see if the width/height has been set, if not then just store the current url, redirect to page1, store the value and rediret them back to the page they were visting.

Hope this helps.
