[Qt-interest] WG: QT Assistant and ports

[Lodron, Gerald]

OK, one entry in netstat -ba is

 TCP    0.0.0.0:2346           DIBW154:0              ABHÖREN
[ReDeformApp.exe]

2346 is my port and ReDeformApp.exe my programm where i listen for incoming messages

When i open assistant.exe and start netstat -ba again i get the same entry:

Es konnten keine Besitzerinformationen abgerufen werden.
 TCP    0.0.0.0:2346           DIBW154:0              ABHÖREN
[ReDeformApp.exe]

And i cannot see any assistant.exe, what does this mean? Here is the way i start assistant.exe:

    if (!m_poHelp)
        m_poHelp = new QProcess();

    if (m_poHelp->state() != QProcess::Running) 
    {
        //QString strApp = QLibraryInfo::location(QLibraryInfo::BinariesPath) + QDir::separator();
        QString strApp;
        QStringList oArgs;

        strApp += QLatin1String("assistant.exe");
        oArgs  << QLatin1String("-collectionFile") << QLatin1String("doc/ReDeformHelp.qhc") << QLatin1String("-enableRemoteControl");

        try
        {
            m_poHelp->start(strApp, oArgs);

            if (!m_poHelp->waitForStarted()) 
            {
                QMessageBox::critical(0, QObject::tr("ReDeform help"), QObject::tr("Unable to launch Qt Assistant (%1)").arg(strApp));
                     return;
            }
        }
        catch(...)
        {
            QMessageBox::critical(0, QObject::tr("ReDeform help"), QObject::tr("Caught exception from (%1)").arg(strApp));
                return;
        }



If i open the assistant.exe from external over explorer my program keeps working, so i only get no port if i open the assistant over code. I also tried without enableRemoteControl but it doesn't have an effect, i also tried:

    std::stringstream oCall;
    oCall << "start assistant.exe -collectionFile doc";
    oCall << QDir::separator().toAscii();
    oCall << "ReDeformHelp.qhc";

    system(oCall.str().c_str());

But its the same, i really have no clue because my receiving thread/code has nothing to do with the assistant... (I use the QtConcurrentRun to make a new thread, thats the only QT thing i do in the receiving...)

Best regards

You didn't provide either of those - your example is not compilable or self- contained. 

Just post on the list, it will be fine.
