我想改变主音量与功能C++ WINAPI waveOutSetVolume()
MMRESULT waveOutSetVolume(
HWAVEOUT hwo,
DWORD dwVolume
);
hwo
Handle to an open waveform-audio output device. This parameter can also be a device identifier.
如何创建主音量的处理程序?
dwVolume
Specifies a new volume setting. The low-order word contains the left-channel volume setting, and the high-order word contains the right-channel setting. A value of 0xFFFF represents full volume, and a value of 0x0000 is silence.
If a device does not support both left and right volume control, the low-order word of dwVolume specifies the volume level, and the high-order word is ignored.
如何将体积(例如75)传递给函数?
像这样尝试:How to change master volume programmatically?不适合我!
谢谢,但WASAPI包含一个函数,只需要卷和处理程序作为输入,如WINAPI函数? –
这不是一个单一的功能。我将相关的MSDN页面链接成为您的主角。 –
好吧谢谢,我会用它! –
