PC喇叭发声问题？急

[96pp]

怎么调用API函数控制PC喇叭发声？
用其他方法也可以，能实现就给分，分不够再加

[freeliu]

beep()就行。不用api.

Beep(n)
Causes the computer to beep up to 10 times.
n The number of times you want the computer to beep. If n is greater than 10, the computer beeps 10 times

谢谢各位，beep（）发声在有声卡的情况下，声音由声卡发出声音，在无声卡或
声卡被禁用的情况下才由PC喇叭发声，我希望实现的是在有声卡的情况下由PC喇叭发声！

问题也解决。
谢谢各位！！
方法是调用API函数实现！
FUNCTION ulong Beep(ulong dwFreq,ulong dwDuration) LIBRARY "kernel32.dll"

加分

[cliving]

Private Declare Function Beep Lib "kernel32" (ByVal dwFreq As Long, ByVal dwDuration As Long) As Long
第一个参数是频率
第二个参数是时间.

beep()
MessageBeep()
