Client Server

hi everybody

ı am prepairing a client programme which takes data from server.how can ı take data from server.

Which kind of server do you have?

Hi again,

I am writing a socket programme and i send data to my server.

Code:

---

bool TcpClient::connectToServer()
{
    if(!isConnectionOpen())
    {
        tcpSocket->connectToHost(_serverAddress,_serverPort);
    }
    return true;
}
 
QString TcpClient::sendMessageToServer(QString sendMsg)
{
    if(!isConnectionOpen())
    {
        connectToServer();
    }
    tcpSocket->write((sendMsg+"\n").toAscii().data());
    return "OK";
}

---

This function is return OK. I want to return response from server. For example;

My send data : Hello
Server Response : blablabla
this function's response : blablabla

How can I return response from server. I use TCP-IP protocol.

the better solution is use the signal/slot mechanism connecting the QAbstractSocket::readyRead() signal with one custom slot.

If you want use a single method that sends and receives data you must use code like:

Code:

---

tcpSocket->write((sendMsg+"\n").toAscii().data());
bool ready = false;
while (!ready)
{
    // Wait for data received
    ready = tcpSocket->waitForReadyRead();
    // Check if you can read a line \n terminated
    ready &= tcpSocket->canReadLine(); 
}
QByteArray ba = tcpSocket->readLine();
QString result(ba);
return result;
