Re: Asynchronous sockets and buffer size

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Sorry, I don't know what I expected with an explanation like that.

here's what my code is like with all the fluff cut out:

private void OnReceive(IAsyncResult asyn)
{
ObjectThing Job = (ObjectThing)asyn.AsyncState;
long BytesReceived = Job.s.EndReceive(asyn);

if (BytesReceived > 0)
{
ProcessData(Job);
Job.s.BeginReceive(Job.buffer, 0, Job.buffer.Length, 0, new AsyncCallback(this.OnReceive), Job);
}

else
{
Job.s.Close();
Job.s = null;
}

}

private void OnSend(IAsyncResult asyn)
{
ObjectThing Job = (ObjectThing)asyn.AsyncState;
Job.s.EndSend(asyn);
Job.s.BeginReceive(Job.buffer, 0, Job.buffer.Length, 0, new AsyncCallback(this.OnReceive), Job);
}

private void OnConnect(IAsyncResult asyn)
{

ObjectThing Job = (ObjectThing)asyn.AsyncState;
Job.s.EndConnect(asyn);
Job.s.BeginSend(Encoding.ASCII.GetBytes(Job.data + "\r\n"), 0, Encoding.ASCII.GetBytes(Job.data + "\r\n").Length, 0, new AsyncCallback(this.OnSend), Job);

}


Job.s is the socket and i call Job.s.BeginConnect(...) to start.

Matthew, I am not quite sure which 'excellent MSDN example' you were following. Normally TCP/IP servers (I assume you do TCP/IP) do not imitate disconnect - clients do. On the server side do not terminate client connection until the client disconnects - BeginReceive() on the server side returns 0, and you will not loose data.
