将 Vb/c++/C# 应用程序静音
本文关键字：应用程序 c++ Vb | 更新日期: 2023-09-27 18:36:05
我需要将我的应用程序静音，因为它使用 5 个网络浏览器并使用 Flash 导航到站点，这可能会导致很多烦人的声音，所以我到处搜索但没有运气我想知道是否有办法通过 vb 代码或任何其他语言（我将制作一个插件）将我的应用程序或我的 Web 浏览器静音。提前感谢您的帮助。
在 Windows Vista 及更高版本中，您可以通过调用 winmm.dll 中的函数来设置单个应用程序的音量
[DllImport("winmm.dll")]
private static extern int waveOutSetVolume(IntPtr hwo, uint dwVolume);
并调用以下静态方法：
public static void MuteApplication()
{
int NewVolume = 0;
uint NewVolumeAllChannels = (((uint)NewVolume & 0x0000ffff) | ((uint)NewVolume << 16));
waveOutSetVolume(IntPtr.Zero, NewVolumeAllChannels);
}
我认为您需要设置IExplorer的配置，这是播放声音的过程。
您可以使用注册表设置一个标志来不播放声音：
在此键：
HKEY_CURRENT_USER'Software'Microsoft'Internet Explorer'Main
值名称：
Play_Background_Sounds
数据：
no
前段时间我做了一个管理Regedit操作的类，你可以像这样使用它：
RegEdit.Set_Value("HKCU'Software'Microsoft'Internet Explorer'Main", _
"Play_Background_Sounds", _
"no", _
Microsoft.Win32.RegistryValueKind.String)
RegEdit.Set_Value("HKCU'Software'Microsoft'Internet Explorer'Main", _
"Play_Background_Sounds", _
"yes", _
Microsoft.Win32.RegistryValueKind.String)
这是类：
