Qt network access manager

[Arpitgarg]

Hi,
I want to implement fortune server/client example on a different IP. Well I changed the code which finds the IP Addr with this one.

QString ipAddress="10.0.0.132";
 QHostAddress(QHostAddress("10.0.0.132") );

QString ipAddress="10.0.0.132";
 QHostAddress(QHostAddress("10.0.0.132") );

To copy to clipboard, switch view to plain text mode 

and in network access manager

QNetworkConfigurationManager manager;
    if (manager.capabilities() & QNetworkConfigurationManager::NetworkSessionRequired) {
        // Get saved network configuration
        QSettings settings(QSettings::UserScope, QLatin1String("Trolltech"));
        settings.beginGroup(QLatin1String("QtNetwork"));
        const QString id = settings.value(QLatin1String("DefaultNetworkConfiguration")).toString();
        settings.endGroup();
 
        // If the saved network configuration is not currently discovered use the system default
        QNetworkConfiguration config = manager.configurationFromIdentifier(id);
        if ((config.state() & QNetworkConfiguration::InternetAccessPoint) !=
            QNetworkConfiguration::InternetAccessPoint) {
            config = manager.defaultConfiguration();
        }
 
        networkSession = new QNetworkSession(config, this);
        connect(networkSession, SIGNAL(opened()), this, SLOT(sessionOpened()));

QNetworkConfigurationManager manager;
    if (manager.capabilities() & QNetworkConfigurationManager::NetworkSessionRequired) {
        // Get saved network configuration
        QSettings settings(QSettings::UserScope, QLatin1String("Trolltech"));
        settings.beginGroup(QLatin1String("QtNetwork"));
        const QString id = settings.value(QLatin1String("DefaultNetworkConfiguration")).toString();
        settings.endGroup();

        // If the saved network configuration is not currently discovered use the system default
        QNetworkConfiguration config = manager.configurationFromIdentifier(id);
        if ((config.state() & QNetworkConfiguration::InternetAccessPoint) !=
            QNetworkConfiguration::InternetAccessPoint) {
            config = manager.defaultConfiguration();
        }

        networkSession = new QNetworkSession(config, this);
        connect(networkSession, SIGNAL(opened()), this, SLOT(sessionOpened()));

What gave you this error?

[Arpitgarg]

well i simply changed these two things

1. code for selecting IP addr
2. In network access manager i changed

NetworkConfiguration::InternetAccessPoint

NetworkConfiguration::InternetAccessPoint

To copy to clipboard, switch view to plain text mode 

i want to run the example on a IP provided by me.
pls help

But what gave you this error? A postman came and handed you a piece of paper with the error written on it?

[Arpitgarg]

QT doesn't show any other build issue.

I am not sure my code is right.

it gave an error ::Cannot retrieve debugging output!

Actually, this means that you have an instance running and you are trying to run another one. Qt recieves output from the first running instance, so it is not able to handle the second one. See your task manager to kill all instances of your application.

Hope it helps you for future
