Trouver le répertoire "Démarrer" de Windows avec JNA Empty Trouver le répertoire "Démarrer" de Windows avec JNA

Message  Gus Lun 10 Déc - 11:20

Le répertoire "Démarrer" de Windows est ce fameux répertoire ou on peut placer des raccourcis des programmes qu'on souhaite démarrer automatiquement au lancement de Windows. Son emplacement dépend du type de Windows mais aussi de la langue. Il n'est pas évident à détecter de manière fiable et aucune variable env disponible par la classe System ne permet a priori de le trouver.

Grâce à l'API JNA (Java Native Access), une API dont j'ai déjà eu souvent l'occasion de vous parler (et ça va continuer), il est possible de trouver ce répertoire, de la manière suivante :

Voici tout d'abord la classe CSIDL qui recense toutes les constantes CSIDL (Constant Special Item ID List) de Windows
(valeurs récupérées à partir du lien : http://www.installmate.com/support/im7/using/symbols/functions/shpath.htm)

Code:

}

Et voici le code qui appelle la méthode SHGetFolderPath à partir de la bibliothèque native Shell32 :

Code:
    private File findStartUpFolder() throws Exception
    {
       if(!Platform.isWindows())
          throw new Exception("Incompatible OS");

       String path = findWinFolderPath(CSIDL.CSIDL_ALTSTARTUP);
       if(path==null) return null;
       return new File(path);
    }
   
   
    private String findWinFolderPath(int nFolder)
    {
       int dwFlags = Shell32.SHGFP_TYPE_CURRENT;
       char[] pszPath = new char[Shell32.MAX_PATH];
       int hResult = Shell32.INSTANCE.SHGetFolderPath(null,nFolder,null,dwFlags,pszPath);
       if(hResult != Shell32.S_OK) return null;

       String path = new String(pszPath);
       int len = path.indexOf('\0');
       return path.substring(0,len);
    }


    private static Map<String,Object> OPTIONS = new HashMap<String,Object>();
   
    static
    {
        OPTIONS.put(Library.OPTION_TYPE_MAPPER, W32APITypeMapper.UNICODE);
        OPTIONS.put(Library.OPTION_FUNCTION_MAPPER,W32APIFunctionMapper.UNICODE);
    }

    static class HANDLE extends PointerType implements NativeMapped {}

    static class HWND extends HANDLE {}

   
   
    static interface Shell32 extends Library
    {
       static Shell32 INSTANCE = (Shell32) Native.loadLibrary("shell32",Shell32.class, OPTIONS);

       public static final int MAX_PATH = 260;
        public static final int SHGFP_TYPE_CURRENT = 0;
        public static final int SHGFP_TYPE_DEFAULT = 1;
        public static final int S_OK = 0;
       
        public int SHGetFolderPath(HWND hwndOwner, int nFolder, HANDLE hToken, int dwFlags, char[] pszPath);
    }
