<P align=left></FONT>这样通过修改注册表Key键值，然后通过调用该方法就能实现对按键声音的设置。</P></DIV>
<P
align=left>对Screen和Mute的设置也可以用该方法，至此，对WINCE各种音量的设置就基本掌握了。希望能给大家点帮助。<BR><BR><BR>Walzer评点:<BR><FONT
face=Verdana>这篇文章不仅写的是WaveOutSetVolume这个API的使用, <FONT
face=Verdana>还包括了系统注册表里对应于控制面板音量调节的修改</FONT>.
并且提到了我们惯用的“暴力调用API”方法。</FONT><BR></P></DIV></DIV>
