.net - 如何在 WebBrowser Control 中禁用点击声音

Question

我使用 Javascript 单击 webbrowser 控件中的链接。但我不想听到 IE 的“咔嗒”声。

有没有办法做到这一点？

附言

我不想更改系统设置。

我见过这个( HowTo Disable WebBrowser 'Click Sound' in your app only )，但 Document.Write 不是我的选择。

对于 IE7 及以上，你可以使用这个:

int feature = FEATURE_DISABLE_NAVIGATION_SOUNDS;
CoInternetSetFeatureEnabled(feature, SET_FEATURE_ON_PROCESS, true);

使用以下 DLL 导入

private const int FEATURE_DISABLE_NAVIGATION_SOUNDS = 21;
private const int SET_FEATURE_ON_THREAD = 0x00000001;
private const int SET_FEATURE_ON_PROCESS = 0x00000002;
private const int SET_FEATURE_IN_REGISTRY = 0x00000004;
private const int SET_FEATURE_ON_THREAD_LOCALMACHINE = 0x00000008;
private const int SET_FEATURE_ON_THREAD_INTRANET = 0x00000010;
private const int SET_FEATURE_ON_THREAD_TRUSTED = 0x00000020;
private const int SET_FEATURE_ON_THREAD_INTERNET = 0x00000040;
private const int SET_FEATURE_ON_THREAD_RESTRICTED = 0x00000080;

...

[DllImport("urlmon.dll")]
[PreserveSig]
[return:MarshalAs(UnmanagedType.Error)]
static extern int CoInternetSetFeatureEnabled(
int FeatureEntry,
[MarshalAs(UnmanagedType.U4)] int dwFlags,
bool fEnable);
