    Default Qt4.1, TCP-server, Ethernet, Windows

    My code gives me packets loss:
    Qt Code:
    1. clientConnection = new QTcpSocket(this);
    2. tcpServer = new QTcpServer();
    3. connect(tcpServer, SIGNAL(newConnection()), this, SLOT(newConnect()));
    4.  
    5. void frmMain::newConnect()
    6. {
    7. clientConnection = tcpServer->nextPendingConnection();
    8.  
    9. connect(clientConnection, SIGNAL(readyRead()),
    10. this, SLOT(receivePkg()));
    11.  
    12. connect(clientConnection, SIGNAL(disconnected()),
    13. clientConnection, SLOT(deleteLater()));
    14. }
    15.  
    16. void frmMain::receivePkg()
    17. {
    18. read_size = clientConnection->read(buf_c, READ_BUF_SIZE);
    To copy to clipboard, switch view to plain text mode 

    Tell me how to create TCP-server:

    -received 10+ packets (1 packet length = 200+ bytes) per 1 ms
    -received packets for 10+ min
    -without packets loss

    May be I have to use another thread and set priority to thread.

    Give me server code, please.

    Maybe you could try this instead of asking us to cook and serve your dinner to you.

    Please use CODE tags when posting source code so it is more readable. Click "Go Advanced" and then the "#" icon to insert the tags. Paste your code between them.
