I have created a socket listener which reads data from the specific port and works fine if I run this application clicking on exe. But when it runs from window startup then socket listener can not read data from socket.

Following code is in Form1_Load function

UdpClient udpClient = new UdpClient(8010);
while (true)
{
    IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any, 0);
    Byte[] receiveBytes = udpClient.Receive(ref RemoteIpEndPoint);
    string returnData = Encoding.ASCII.GetString(receiveBytes);

}

I'm sure that sometime while asking your almost 60 questions you've come along [How do I ask a good question?](http://stackoverflow.com/questions/1432213/copy-file-on-a-network-shared-drive). "socket listener can not listen" is not a proper problem description. – CodeCaster Jul 09 '15 at 10:34
Your edit does not help much. Why can't it read data? Does it hang? Throw an exception? Return an empty byte array? Why do you do a `while (true)` in the Form_Load event handler anyway? – CodeCaster Jul 09 '15 at 10:44
What do you mean by window startup ? Is it a service or is it executed before or after user login ? – Graffito Jul 09 '15 at 10:52
It executes after user login. – MD SHAHIDUL ISLAM Jul 09 '15 at 10:55
If you run the command "netstat -a -p UDP -b", are you listening on port 8010? – Graffito Jul 09 '15 at 11:29
Yes listening on port 8010 – MD SHAHIDUL ISLAM Jul 09 '15 at 11:43
What happens if you insert a System.Threading.Thread.Sleep(100) in the while loop ? – Graffito Jul 09 '15 at 13:08
