Problem with relative paths when my app is lunched at windows startup

[SimoLab]

Hi everybody,
I created a reminder app that plays some mp3 files at specific times using QMediaPlayer an QMediaPlaylist. Those files are loaded in the playlist using relative paths. I added also the possibility to lunch the app by command line arguments at windows startup.
the problem is when the app is lunched at startup ( HKLM\...\Run) the mp3 files are not loaded in the playlist BUT when i add the app .exe shortcut with the same command line arguments to the startup folder (AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup) mp3 files are loaded and everything is OK...
Thanks for your help

         {
           w.startUp();

     }
   else
 
    w.show();

Ok i solved the problem by using QCoreApplication::applicationDirPath () because when my app is started with windows the working directory changes to SysWOW64.

An option is to build them into your executable using the Qt resource system... then you simply cannot misplace them.

Read about QCoreApplication::applicationDirPath() and work with absolute paths.
