showing Custom error message to the user7/9/2007 5:55:13 AM

Hi,

I am developing a project in which i have to use exception handling.......I want that wheneever as exception occurs that time i will show a custom error message to the user......some people are suggesting to use web.config file ..Below is the code i have to write in web config file..

<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">

<error statusCode="403" redirect="NoAccess.htm" />

<error statusCode="404" redirect="FileNotFound.htm" />

</customErrors>

But problem is that for each error i have to create a separate error file........AND i don't know at runtime which type of error will be generated...

If is there any better way to sohw the custom errror message to user.......Kindly help me.......Plz write ur opinion briefly

If you remove

<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
from web.config user will be redirected to GenericErrorPage.htm every time error happens.

1. Remove this part from web.config:

<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
2. Create Global.asax file in root folder and put this inside it:
<%@ Application Language="C#" %>

<script RunAt="server">

 void Application_Start(object sender, EventArgs e)
 {

 }

 void Application_End(object sender, EventArgs e)
 {

 }

 void Application_Error(object sender, EventArgs e)
 {
  Session["error"] = Server.GetLastError().Message.ToString();
  Server.ClearError();
  Server.Transfer("~/error.aspx");
 }

 void Session_Start(object sender, EventArgs e)
 {

 }

 void Session_End(object sender, EventArgs e)
 {

 }
      
</script>

3. Create error.aspx file like this

Page:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="error.aspx.cs" Inherits="error" %>

<!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>Error</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
  <asp:Label ID="Label1" runat="server"></asp:Label></div>
    </form>
</body>
</html>

Code-behind:
using System;
using System.Data;
using System.Configuration;
using System.Collections;
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 error : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
  Label1.Text = Session["error"].ToString();
    }
}
