Seriennummer der Systemplatte...

[mkinzler]

Zitat:

Ob du das String auch noch in ein AnsiString änderst, ist dir überlassen. (ist vermutlich aber nicht nötig)

Wenn schon, denn schon

[Chriscode]

Ouch, dummer Fehler. Bitte um Verzeihung.

Vielen Dank für die blitzschnelle Hilfe. Man sollte bei c&p halt trotzdem sein Hirn einschalten

Gruß

...und immer daran denken:
Unter VISTA und WIN 7 laufen manche Programme nur mit Administratorrechten -> Rechtsklick: Als Administrator ausführen.

[Luckie]

Aber doch nicht, um die Seriennummer auszulesen. Und wenn dem so wäre, hätten die Programme schon unter XP nicht funktioniert, wenn man nur als Benutzer mit eingeschränkten Rechten arbeitet.

Zitat von Luckie:

hätten die Programme schon unter XP nicht funktioniert, wenn ...

Wenn nicht sogar früher. (WinNT + neues Rechtesystem, bzw. ab NTFS oder ab einer bestimmten NTFS-Version)

[Luckie]

WinNT habe ich nicht erwähnt, weil er da wahrscheinlich noch nicht mal in Planung war.

GetPhysicalDriveHandle ist das Problem. Es braucht Administrator-Rechte bei WIN 7.
