How to disable click sound in WebBrowser Control

Question

I use Javascript to click a link in the webbrowser control. But I don't want to hear IE's "click" sound.

Is there any way to do this?

P.S.

• I don't want to change system settings.
• I've seen this one (HowTo Disable WebBrowser 'Click Sound' in your app only) but Document.Write is not an option for me.

For IE7 and above, you can use this:

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

using the following DLL imports

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);
