Indeed they are both supported in IE 7 and FireFox (i tested with 2.0.0.6). Just try it:
<html>
<body OnBeforeUnload="alert('before');" OnUnload="alert('unload');">
</body>
</html>

Set the Page_ValidationActive javascript variable to false in the button's OnClick event.
This works:
In your ASPX (had to remove beginning angle brackets to get it to render on CP ):
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
asp:RequiredFieldValidator runat="server" id="rfv" ControlToValidate="txt" ErrorMessage="Error"></asp:RequiredFieldValidator>
asp:TextBox runat="server" ID="txt"></asp:TextBox>
asp:Button runat="server" ID="btn" Text="Go" OnClick="btn_Click" />
</div>
</form>
<script>
function TurnOffVal()
{
Page_ValidationActive = false;
}
</script>
</body>
</html>
And in the code behind:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
btn.Attributes.Add("onclick", "TurnOffVal();");
}
protected void btn_Click(object sender, EventArgs e)
{
Response.Redirect("http://www.codeproject.com");
}
}

me how to make a website live. (who says developers don't have humor  )
Anyways Assming you have finished developeing your site and want to put it live:
First you'll need a server to deploy your website on (this server should have a permanent connection to the net or your website will be offline when the server is)
Then you'll need to register a domain you want your site to be in eg. http://www.mysite.com , you can do this at www.thatip.com , also before you can register your domain you'll need to find out the IP address of the server mentioned above and find out if it is a dynamic IP static IP, this youll need to setup your ThatIP account (note: if your IP is dynamic you'll need a program like WinIP on the server to keep track of your IP changes)
Once your site is registered and properties set you'll need to deploy the website on the server using a program like apache or IIS(Microsoft: Assuming you have windows XP you must install this from the XP disk as it is not installed by default). look up a muanual on how to deploy your specific web technology on the net there should be one on google. also if you are running a ASP.NET site you'll have to register your class library using the command promt depending on your asp.net version. eg, c:\windows\microsoft.net\framework\[myframeworkversion]\aspnet_regiis.exe /i
Hope this helps

Hi, over the last 7 moths I have been coding dynamic websites, and for 5 months been working with ajax.
I would like to know how can I speed up the data access speeds and in general website speed.
1) Dataset .xsd file as a data access layer: I used this in some of my Windows applications as data access layer: is there any advantage to using this instead of the conventional way of creating a query string and filling a dataset using a SQLDataAdpater?
2)LINQ <-- not sure what this is, but is there any advantages to using this how on .NET Fw 2 I saw this get realeased with the Visual studio Orcas
3) Stored Procedures < - I had lots of mixed commetary about this (Some say its precompliled other dont)
4) Putting all your ASPX & ASPX.CS code in a single line and saving the file makes the file smaller (thus faster to load on client) ???
If anyone can point me to a good tutorial or documentation that explains these issues it would be greatly appricated.

Step one. Max out your memory on the database server. If it holds a maximum of four gigs get a new server that can hold more. Memory is the best way to get speed for data processing. A fast CPU cant hurt either. With data, it's all about the processing. To get speed you need WIDE PIPES.
Step two. If you are interested in performance, the more layers you add, the slower you will be.
1. .xsd is the filename extension for an XML schema which means you are really talking about data transfer via XML. This carries a lot of overhead as a method of transporting data.
2. LINQ is Microsoft's new language for ameliorating various enteties (data sets, XML, class objects) using a single query language. Again good for amelioration, but carries overhead which means you are sacraficing speed.
3. Stored procedures. (YES!! Use them! Use them often!)
4. NO, that's just wrong. It all ends up as .NET assemblies in the Common Language Runtime anyway. If anything, it will slow down people's ability to grok the code.
As far as tutorials go, wikipedia your terms and you'll have a better understanding of what you ask.
Dot Net Rocks! and Arcast(Ron Jacobs) have a lot of good podcasts with this topic. Listening to podcasts is one of the most efficient ways to pick up on the basics.
I am sure there are a lot of optimizations that take place on your database server software of choice. I'm not a DBA though so I really can't speak to that. A good reference will help here. (Or you can just hire a good DBA!)

Hi Guys,
I'll be starting to work on web app that would send out massive mails for our clients campaign (approx 20k per batch), the webserver's and mail server are being hosted on our end so we have the complete control of the platform.
I'm just wondering:
1. What would it takes me to maintain a high volume of mails being received by our mail server
2. Would it be possible to have another mail server where we could crate a load balance for the volumes of mails?
3. Can you give reference / URL where I could check on the design for this kind of web apps.
Thanks
Dom

I'm interested to see your code... I tried doing a quick implementation to see what happens, and while i can manage to lock the scrolling in FF, it doesn't seem to be possible in IE6...
function moveUp()
{
var list = document.getElementById("theList");
var sel = list.selectedIndex;
if ( sel > 0 )
{
repositionOption(list, sel, sel-1);
}
}
function moveDown()
{
var list = document.getElementById("theList");
var sel = list.selectedIndex;
if ( sel < list.length-1 )
{
repositionOption(list, sel, sel+1);
}
}
function repositionOption(list, sel, index)
{
var scroll = list.scrollTop;
var opt = list.item(sel);
list.remove(sel);
opt.selected = false;
try
{
list.add(opt, list.item(index));
}
catch(e)
{
list.add(opt, index);
}
list.scrollTop = scroll;
opt.selected = true;
}

$sl = $obj.selectedIndex;
var scroll = $obj.scrollTop;
if($obj.options[$sl].text==$EXCLUDE || $obj.options[$sl].value==$EXCLUDE){alert("This item cannot be altered.");return false}
if ($sl != -1 && $obj.options[$sl].value > "") {

if ($obj.options[$sl].value > "" && $sl > 0 && $down == 0) {
if($obj.options[$sl-1].text==$EXCLUDE){alert("This item cannot be moved into that position.");return false}
$obj.options[$sl].text = $obj.options[$sl-1].text;
$obj.options[$sl].value = $obj.options[$sl-1].value;
$obj.options[$sl-1].text = $oText;
$obj.options[$sl-1].value = $oValue;
$obj.selectedIndex--;
$obj.scrollTop = scroll;
} else if ($sl < $obj.length-1 && $obj.options[$sl+1].value > "" && $down == 1) {

$obj.scrollTop = scroll;
}
return true;
} else {
alert("Please select an item first.");
return false;

}
orderSelect is called in the onclick event for an image input. Thanks for the help!

Ah, well that's a bit different. Try restoring the scroll position before modifying the selected index - that ought to let FF keep the selection in view. If not, then try also changing <span>$obj.selectedIndex++</span> to <span>$obj.options[$sl+1].selected = true</span>.

No.
There are... thousands of different designs and implementations for such things. Without knowing what your requirements and constraints are, it's pretty much pointless to try and pick one for you. Personally, i don't care much for 'em. It's a web page, not a desktop app - you have enough menus already.
So,
Try doing a search here on CP. Then do a search on Google. Then check out this site[^]. Then sit and think about all that for a good while. Maybe talk to other people involved in whatever it is you're making, see what they think.
Then, when you have a specific question, come on back...

Hi,
i am developing a website using classic asp in internet explorer.
Its login page is workig fine ,when i copy the address from the address bar of a protected page,it redirect me to the login page.
but am doing the same copy and past thing with firefox,it is not redirecting me to the login page,instead to the protected page. wat can i do?
this is part of the code in the protected page:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd"><br />
<html><br />
<head><br />
<title></title><br />
<% <br />
If Session("blnValidMember") <> True Then <br />
Response.Redirect("login.asp") <br />
End If <br />
%> <br />
<%<br />
Response.Expires = -1000<br />
Response.Expiresabsolute = Now() - 1 <br />
Response.AddHeader "pragma","no-cache" <br />
Response.AddHeader "cache-control","private" <br />
Response.CacheControl = "no-cache" <br />
%><br />
<br />
</html>
this is part of the code in the validating page
<%<br />
'Declare variables<br />
Dim oConnection, oRecordset, sSQL,sql2,rs,dr,strSQL<br />
Dim UserName, sPassword<br />
<br />
'Receive the form values and assign to sUserName and sPassword variables<br />
Username = Request.Form("txtUsername")<br />
sPassword = Request.Form("txtPwd")<br />
<br />
'If Username=sAdminUsername AND sPassword=sAdminpassword Then<br />
'Session("blnValidMember") = True<br />
'Session("Admin")=True<br />
'response.redirect "admin/approve.asp"<br />
'Else<br />
'Create a connection odject and a recordset object<br />
Set oConnection = Server.CreateObject("ADODB.Connection")<br />
Set oRecordset = Server.CreateObject("ADODB.Recordset")<br />
set rs= Server.CreateObject("ADODB.Recordset") <br />
<br />
oConnection.Open sConnString<br />
<br />
sSQL = "SELECT username, password FROM clientlist WHERE username ='"& UserName & "'"& _<br />
" AND password ='" & sPassword & "'" <br />
oRecordset.Open sSQL, oConnection<br />
If NOT oRecordset.EOF Then<br />
'If its a valid login then set the session variable to True<br />
Session("blnValidMember") = True<br />
<br />
Else<br />
<br />
Session("blnValidMember") = False<br />
Response.Redirect "errorpage.asp"<br />
End If<br />
<br />
%><br />
thank you in advance

Looking at that code, it looks as though you must have had a active session in FF. Maybe you had already logged in and forgot about it. Clear everything out in FF and try again.
