只要更新了注册表,然后调用该函数,则系统会根据键值来进行相应的调整.<BR>
<BR>
那么现在让我们来看看位于"ControlPanel\Volume"注册表中各键值的意义:<BR>
<BR> Volume:
系统的主音量,范围是0x0 ~ 0xFFFFFFFF.<BR>
<BR> Screen: 屏幕敲击声.
当数值为0时即为无声,1为柔和,65538为洪亮<BR><BR> Key:
键盘敲击声,数值的意义和Screen相同.<BR>
<BR> Mute: 控制其它静音的选项.
置0x04位为1时允许事件声音,0x02允许应用程序声音,0x01允许警告声.需要注意的是,如果不允许应用程序声音,则警告声位也将被忽略.<BR>
<BR>
<BR>
如果每次更改音量都要改写注册表,调用动态链接库,会显得比较麻烦.为了写代码的便利,在此封装了这个声音的操作:<BR>(注:CReg
