hi Leute hab folgendes Problem. Ich hab mir mit dem bcbuilder 5 ein programm gemacht, welches die Attribute von Dateien ändert. Ich hab nur das Problem dass ich die Bitflags nicht richtig setzen kann(weis nicht wie) um die Attribute zu löschen. Aktivieren ****zt gut aber ich schaff es nicht die Attribute zu deaktivieren.
Bitte hilfe. Danke

Code :
