Unable to run the WMIC command through QProcess in Qt6.4.0

[Pradson]

Hi,

As, I mentioned below code, I am unbale to read standard output of the WMIC command. I am using Qt6.4/MSVC2019 to build the code. But this code is working fine with Qt5.12.3/MSVC2017. Kindly help me regarding this.

QProcess objCheckInstance;
QStringList args;
args << "process where \"Caption=\'" + a.applicationName() + ".exe\'\" get processid";
objCheckInstance.start("wmic", args);
if(objCheckInstance.waitForStarted())
    {
        QString qszOutput;
        if(objCheckInstance.waitForFinished())
        {
            qszOutput.clear();
            qszOutput = objCheckInstance.readAllStandardOutput();
            qDebug() << "test" << qszOutput;
        }else
        {
            qDebug() << "test2" ;
        }
    }

Thanks,

@Pradson What about adding error handling?
For example https://doc.qt.io/qt-6/qprocess.html#errorOccurred
You also did not mention whether waitForStarted()/waitForFinished() time out or not.

@Pradson
Apart from obviously putting in error handling if you want help with errors as @jsulm says. Did you try making that command line separate arguments instead of a single one? Did you try running just a command with empty arguments of wmic?
