Windows cmd.exe startDetached fails

Jedd

I recently updated from Qt 5.6 to Qt 5.10.1 and the function below now fails to work. Windows console is not opened when the function is called. I rechecked with a recompile using 5.6 and the function works fine. Why does this code work with 5.6 and previous releases and not with Qt 5.10.1?

 void MainWindow::on_doConsole_clicked()
 {

    QString commstr = adbdir+"cpath.bat";
    QFile file(commstr);

        if(!file.open(QFile::WriteOnly |
                  QFile::Text))
        {
            logfile("error creating cpath.bat!");
            QMessageBox::critical(this,"","Error creating bat file!");
            return;
        }

        QTextStream out(&file);
        out  << "set PATH=%PATH%;"+QDir::currentPath()+";"<< endl;

        file.flush();
        file.close();

        cstring = "cmd /k " +QDir::currentPath()+"/cpath.bat";
        QProcess::startDetached(cstring);

}

Hi,

Please read the part of the QProcess documentation about CreateProcessArgumentModifier.

It'll show you have to handle your use case.
