HowTo retrieve a users Screen.Height???
Well,
I wonder if it's possible to read a user's screen resolution from ASP.
In the same way as you can with ex JavaScript
<SCRIPT LANGUAGE="JAVASCRIPT">
userScreenHeight = screen.height;
</SCRIPT>
I'm running VBScript in my asp-pages, and for some reason this code fails:
<%
DIM LinesPerPage
LinesPerPage = 19
IF Screen.Height = 600 THEN
LinesPerPage = 13
END IF
%>
And then when i out-comment the IF-block, the code runs without errors.
Now please, Ladies or Gentlemens what should I test for in my IF-block??

Re: HowTo retrieve a users Screen.Height???
You've confused server-side VBScript with client-side JScript. The server
doesn't have access to the user's screen resolution unless you obtain it
from the client and post it back. If you write the code as client-side code,
it works fine:
<script language="VBScript">
userScreenHeight = screen.height
</script>
If you need to know the user's screen resolution on the client, try
something like this. You can paste the code below into an empty ASP page.
*********************************
<%@ Language=VBScript %>
<%
' GET or POST
Dim IsPostBack
If Session("ScreenX") = "" then
' if this page is a POST request then check to see
IsPostBack = (Request.ServerVariables("REQUEST_METHOD") = "POST")
if IsPostBack then
if Request.Form("x") <> "" then
Session("ScreenX") = Request.Form("x")
Session("ScreenY") = Request.Form("y")
end if
else
With Response
.Write "<html><head></head><body>"
.Write "<form id=""frmResolution"" name=""frmResolution""
method=""post"">" & vbcrlf
.Write "<input type=""hidden"" id=""x"" name=""x"">" & vbcrlf
.Write "<input type=""hidden"" id=""y"" name=""y"">" & vbcrlf
.Write "</form>" & vbcrlf
.Write "<scri"
.Write "pt language=""VBScript"">" & vbcrlf
.Write "document.getElementById(""x"").value = Screen.Width" & vbcrlf
.Write "document.getElementById(""y"").value = Screen.Height" & vbcrlf
.Write "document.getElementById(""frmResolution"").submit" & vbcrlf
.Write "</script>" & vbcrlf
.Write "</body></html>"
.End
End With
end if
End If
%>
<HTML>
<HEAD>
</HEAD>
<BODY>
<P>Your screen resolution is <%=Session("ScreenX")%>,<%=Session("ScreenY")%>
</P>
</BODY>
</HTML>
