[Qt-interest] HTTP CGI Problems

[Mohammed Sameer]

manager is a pointer, use manager->get() not manager.get()

QNetworkAccessManager *manager = new QNetworkAccessManager;
QNetworkReply *reply = manager->get(QNetworkRequest(QUrl("http://192.168.1.20/something.cgi");
QObject::connect(reply, SIGNAL(finished()), blah, SLOT(blahblah));

Cheers,
