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.

Answer 1

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);

I have wrapped this functionality into a ready-to-use class. I used part of the information from the selected answer and the MSDN reference.

Hope this is useful to someone.

Usage

URLSecurityZoneAPI.InternetSetFeatureEnabled(URLSecurityZoneAPI.InternetFeaturelist.DISABLE_NAVIGATION_SOUNDS, URLSecurityZoneAPI.SetFeatureOn.PROCESS, false); 

URLSecurityZoneAPI

Answer 3

As noted by the comments, and the answer by @James Crowley, it is indeed possible.

If you navigate in IE, and thus that control, you'll get the click. Unless you change the settings, or fake it like that link, then no, you can't get rid of the click.
