<![CDATA[How to open a AutoCad file from Qt]]>Hello, I must open autocad from Qt. How can I open a program (like Autocad) from 0t application? for example, pressing a pushbutton autocad will open. What I want it's a link, something like an Hyperlink

what do you think this:

 QProcess *autocad= new QProcess (this);
    autocad->start("C:\"Program Files\"Autodesk\"AutoCAD 2013\"acad.exe");

    qDebug()<<"process...."<<autocad->error()<<endl;
}

whit the output:

process.... QProcess::ProcessError(FailedToStart)

reggards.

Because you are trying to start a file and not an application. If you would like to launch the application associated with a file type then use QDesktopService::openUrl.

I must open, for example, draw.dwg

 QString path = QStandardPaths::writableLocation(QStandardPaths::DesktopLocation);
    QProcess *autocad= new QProcess;
    autocad->setProgram(path+"Images/draw.dwg");;
    autocad->start();

process.... QProcess::ProcessError(FailedToStart)

autocad->start("C:"Program Files"Autodesk"AutoCAD 2013"acad.exe");

This string will read as C:"Program Files"Autodesk"AutoCAD 2013"acad.exe so its not what you expect,

as @mrjj already said, you have to use the correct escaping

Hi
I think it will work better with
http://doc.qt.io/qt-5/qdesktopservices.html#openUrl

Also , in c++ you must ALWAYS have
\\

so it looks wrongly escaped

autocad->start("C:\"Program Files\"Autodesk\"AutoCAD 2013\"acad.exe");
