please help me...

Hey,

The window basically hangs because you are using the same thread to download the file as well as updating the application.

When you are dealing with background work, it is always recommended to use Thread [^]and invoke the download method from there.

To ping you might use :

public static bool IsConnectedToInternet
       {
           get
           {
               Uri url = new Uri("yoururl");
               string pingurl = string.Format("{0}", url.Host);
               string host = pingurl;
               bool result = false;
               Ping p = new Ping();
               try
               {
                   PingReply reply = p.Send(host, 3000);
                   if (reply.Status == IPStatus.Success)
                       return true;
               }
               catch { }
               return result;
           }
       }

:thumbsup:

i tried this but gave me error, so i did once per each, egain generate error :'(

public static int Ping(string hostname)
{
Ping ping = new Ping();

PingReply reply = ping.Send(hostname);
if (reply.Status == IPStatus.Success)
{
Console.WriteLine("Address: {0}", reply.Address);
Console.WriteLine("RoundTrip Time: {0}", reply.RoundtripTime);
Console.WriteLine("Time To Live: {0}", reply.Options.Ttl);
Console.WriteLine("Don't Fragment: {0}", reply.Options.DontFragment);
Console.WriteLine("Buffer Size: {0}", reply.Buffer.Length);
Console.WriteLine("Status: {0}", reply.Status);

Console.ReadLine();
return (0);
}

{
Console.WriteLine("Error");
Console.WriteLine("Status: {0}", reply.Status);
Console.ReadLine();
return (1);
}
