    Hello,

    I was trying to do this:
    @
    Process->start("cmd.exe",QStringList()<<"C:/Users/Admin/Desktop/test.txt");
    @

    To check if the command works but it doesn't , it shows "" in the app output.

    test.txt is in the desktop and I want to open it.

        Hi,
        try
        Process->start("C:/windows/system32/cmd.exe",QStringList()<<"/C"<<"C:/Users/admin/Desktop/test.txt");
        or wherever your win resides

          Thank you guys , both works fine , but why /C ? I don't use command line much but I don't think it's a command right ?

            It executes the commands that follow as a script. Without it, cmd.exe would be opened and wait for input from keyboard.
