i before write my code to this method 369 book:
void WeatherBalloon::sendDatagram()
{
QByteArray datagram;
QDataStream out(&datagram, QIODevice::WriteOnly);
out.setVersion(QDataStream::Qt_4_3);
out << QDateTime::currentDateTime() << temperature() << humidity()
<< altitude();
udpSocket.writeDatagram(datagram, QHostAddress::LocalHost, 5824);
}
But we want to connect UDP processing data to GUI app, it can not read QDataStream Method and it Crashs. The app is written in C#,So we should try a method that work with VisualStudio.
Agian Than kyou for attention
