Hallo, sorry, das ich das Forum schon wieder mit einer frage belaste und eigentlich geht es ja immernoch um die NDL, aber mein Problem hat eher was mit der Registry zu tun: Ich suche eine Möglichkeit den (Standard) - wert auszulesen (im Verzeichnis: HKEY_LOKALE_MACHINE\Software\Classes\.ndl\Shell\Open\Command) und gegebenenfalls zu ändern. Ich habe gesucht und auch möglichkeiten gefunden in die Reg zu schreiben und auch zu lesen

es funktioniert auch alles, aber wenn ich versuche den wert des Bezeichners (Standard) zu beschreiben, dann legt er einen neuen Bezeichner mit dem selben namen an, den ich auch auslesen kann, aber an den vorgegebenen Standart - wert komme ich nicht ran.
