Now the file get downloaded.. but the problem now is if i download a file in second or other page of the website programmatically.. when i view the downloaded file in local drive it shows the login page of that site only. for example,

using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 
using System.Net; 
using System.IO; 
namespace WindowsFormsApplication4 
{ 
    public partial class Form1 : Form 
    { 
        public Form1() 
        { 
            InitializeComponent(); 
            WebClient Client = new WebClient(); 
            WebProxy proxyObj = new WebProxy("http://ipaddress:port"); 
            proxyObj.Credentials = CredentialCache.DefaultCredentials; 
            Client.Proxy = proxyObj; 
            Client.Credentials = new NetworkCredential("user", "pass"); 
                     
            Client.DownloadFile("http://www.codeguru.com/csharp/.net/net_asp/article.php/c17151/Images-on-the-Fly-in-ASPNET.htm", @"d:\aa.html"); 
            MessageBox.Show("done"); 
        } 
     } 
}

Hi
Actually it is a simple task. Just add your files to a folder called "downloads". Then in drag and drop a hyper-link into your form. Set the properties, and give the file which is in you downloads folder. The browser will automatically shows the popup window.

any doubts ask me.
