最近用MFC做一些小东西，发现了一些对音量的控制，挺简单的，记录一下。

//增大音量:

keybd_event(VK_VOLUME_UP,MapVirtualKey(VK_VOLUME_UP,0),KEYEVENTF_EXTENDEDKEY,0);

keybd_event(VK_VOLUME_UP,MapVirtualKey(VK_VOLUME_UP,0),KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,0);

//减小音量:

keybd_event(VK_VOLUME_DOWN,MapVirtualKey(VK_VOLUME_DOWN,0),KEYEVENTF_EXTENDEDKEY,0);

keybd_event(VK_VOLUME_DOWN,MapVirtualKey(VK_VOLUME_DOWN,0),KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,0);

//静音:

keybd_event(VK_VOLUME_MUTE,MapVirtualKey(VK_VOLUME_MUTE,0),KEYEVENTF_EXTENDEDKEY,0);

keybd_event(VK_VOLUME_MUTE,MapVirtualKey(VK_VOLUME_MUTE,0),KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,0);
