shutdown socket WSAGetLastError 10057

[auliac]

helo friend.....!!!

i try to built an aplication. i got difficult how to break connection between client-server.

void CComputer::OnButtonStart() 
{
...
...
sServer = socket(PF_INET, SOCK_STREAM, IPPROTO_IP);
...
...
}

// my disconnect function
void CComputer::OnButtonStop() 
{
....
....
// try to shutdown
if (shutdown(CComputer::sServer,2)==SOCKET_ERROR)
	{
		info.Format("socket() failed: %d", WSAGetLastError());
               AfxMessageBox(info);
               return;
	}
....
.....
}

from that code i got error "socket() failed: 10057". as we know, that error message come from my shutdown().

how can i repair it???

thanks...
