Client/server application

[sali555]

hi everyone,

i am writing a network application and have one problem. I have server and two clients. The first client send message to server, when this message comes to server, the server send other message to the second client but I dont know how can I do that.

I have this function, which send data to client

void MainWindow::writeData(QTcpSocket* socket, QByteArray data)
{
        socket->write(data);
        socket->flush();
}

void MainWindow::writeData(QTcpSocket* socket, QByteArray data)
{
        socket->write(data);
        socket->flush();
}

To copy to clipboard, switch view to plain text mode 

The first client send message START, the second send "FINISH"
When message FINISH comes, I want to send message HELLO to the client, which sended message START.

sorry about my english
