You need to do it with userlibs (API):
; ### Message Beep
.lib "user32.dll"
MessageBeep%(uType%):"MessageBeep"
Type parameters:
SPEAKER or DEFAULT = -1
MB_OK = 0
MB_ICONHAND = 16
MB_ICONQUESTION = 32
MB_ICONEXCLAMATION = 48
MB_ICONASTERISK = 64
Example:
MessageBeep(128)
Or, for the classic speaker beep with variable frequency
and duration (only for NT/2000/XP), try this:
.lib "kernel32.dll"
Beep%(freq%, duration%):"Beep"
(frequency between $25 and $7fff)
(duration in millisecs)
Example:
Beep($7777, 2000)
