beep怎么能连续响

现在只响一下，就像弹出对话框的声音
频率和长度是不是只能在苹果机的系统下才能设计啊
我是XP系统，设置了跟没设置一样，怎么才能解决？

frequency (Hz) is the frequency of the tone in Hertz. LabVIEW ignores this parameter.
duration (msec) is the duration of the intensity of the tone. LabVIEW ignores this parameter.
intensity sets the intensity of the tone. LabVIEW ignores this parameter. This input can be a value from 0 to 255, with 255 being the loudest.
error returns an error. LabVIEW ignores this parameter.

LabVIEW ignores this parameter. 看这句咯，参数无效
