WINDOWS.BEEP für WINDOWS 7

  Alt 9. Jul 2010, 11:10
Delphi-Version: 2007
Mein "geliebtes" WINDOWS.BEEP(freq,duration) gibt es in WINDOWS 7 nicht mehr.
Hier ist Ersatz mit der Function WINDOWSBEEP(freq,duration).
Wählt die Frequenz nicht zu niedrig (überträgt der Beeper/Lautsprecher nicht)
und nicht zu hoch (hört man im fortgeschrittenen Alter nicht mehr ).

Limits gefunden im C++--Code von 2000:
#define BEEP_FREQUENCY_MINIMUM 0x25
#define BEEP_FREQUENCY_MAXIMUM 0x7FFF

Ein Sleep(xx); zwischen 2 Functions-Aufrufen ist erforderlich: xx habe ich mit 50msec getestet.
Getestet mit WIN XP 32Bit und WIN 7 ULTIMATE 64Bit.
