Qt and Ms PowerPoint communication

[aniljoby]

I have the code to start, run the presentation with 3 seconds delay and to quit. These all done with a single push button click..

QString pptFile = "C:/embedded.pptx";
    CoInitialize(NULL);
    {
        QAxObject pp("PowerPoint.Application", nullptr);
        auto presentations = pp.querySubObject("Presentations");
        auto presentation =  presentations->querySubObject("Open(QString)", pptFile);
        auto slides = presentation->querySubObject("Slides");

        auto sliseshowsettings = presentation->querySubObject("SlideShowSettings");
        sliseshowsettings->dynamicCall("Run()");
        auto slideshowwindow = presentation->querySubObject("SlideShowWindow");
        auto slideshowview = slideshowwindow->querySubObject("View");

        int numSlides = slides->property("Count").toInt();
        for(int i = 1; i < numSlides; ++i) {
                QThread::currentThread()->sleep(3);
                slideshowview->dynamicCall("Next()");
        }
        QThread::currentThread()->sleep(3);
        pp.dynamicCall("Quit()");
    }
    CoUninitialize();

What i want to do is...
I have five push buttons...

1.To start Powerpoint application
2.To start slideshow with first slide
3.To go to next slides
4.To go to previous slides
5.Finally to quit
