Hallo ,
bin schon am verzweifeln.
Ich möchte Programmgesteuert herausfinden, ob der angeschlossene Drucker den Status ONLINE/OFFLINE hat.
Über PRINTER_INFO_5 kann ich PRINTER_ATTRIBUTE auslesen, was so weit funktioniert.
Wenn ich aber den Drucker über Windows (WIN7) auf offline setze, kriege ich den PRINTER_ATTRIBUTE-Wert=0x00000640 und auf Online 0x00000240 beide Werte sind aber in Winspool.h nicht definiert :eek:
Hat jemand ne Idee, ob die beiden Werte wirklich ON/OFFLINE-Status repräsentieren?

Winspool.h Attribute
#define PRINTER_ATTRIBUTE_QUEUED 0x00000001
#define PRINTER_ATTRIBUTE_DIRECT 0x00000002
#define PRINTER_ATTRIBUTE_DEFAULT 0x00000004
#define PRINTER_ATTRIBUTE_SHARED 0x00000008
#define PRINTER_ATTRIBUTE_NETWORK 0x00000010
#define PRINTER_ATTRIBUTE_HIDDEN 0x00000020

jetzt wo ich das sehe macht es natürlich sinn
