Problem with Socket :(

[DickRivers]

Hi,

i'm very new to C# i started programming with #Develop and it's very nice

My goal is to develop a little application in C# that handles a Joystick inputs, with DirectInput from DirectX API i got what i need, i can detect the different inputs from the player (UP, DOWN, Fire, etc), now i need to send those inputs to a Socket Server that i've developped, this server is just a simple echo server, so the server is supposed to echo "LEFT", "RIGHT", "UP" etc it works BUT the bytes are sent to the socket ONLY when i close the application!!! , not when the user press the buttons from the joystick, so it's not very nice for the gameplay hahah

So if i press, LEFT, RIGHT, DOWN, nothing is sent, then i close the application, and at this moment the byes are sent and i see the server echoing the inputs.

I've put my Joystick listening stuff in a Thread, maybe there is something i didn't get as 'im pretty new to this language.

Thanks a lot for your help, i really appreciate

Are you using a Stream object to write to the socket? If so, you should call Flush() after each write.

hi, thanks a lot for your answer, here is how i send the bytes ? is that correct ?

i call the changeTextValue method with a string as parameter, like "LEFT", "RIGHT" etc

private void changeTextValue ( string str )

{

byte[] byData = System.Text.Encoding.ASCII.GetBytes(str);

if ( byData.Length > 0 ) {

m_sock.BeginSend (byData, 0, byData.Length, 0, new AsyncCallback(this.SendCallback), m_sock);

}

myText.Text = str;

System.Console.WriteLine (str);

}

protected void SendCallback(IAsyncResult ar)

{
// Retrieve the socket from the async state object.
Socket handler = (Socket) ar.AsyncState;
try
{
// Complete sending the data to the remote device.
int bytesSent = handler.EndSend(ar);
}
catch (Exception e)
{
}

}

ok, i see what you mean, instead of using the Socket class i can use the TCPClient class, yes i use a stream object to send the message, and i also call the Flush() method on it, but still the same problem, my calls are queued and all sent one the application closed

here is my code :

Byte[] data = System.Text.Encoding.ASCII.GetBytes("LEFT");

NetworkStream stream = myTCP.GetStream();

stream.Write(data, 0, data.Length);

stream.Flush();

How are you reading the data in?
