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 anyway to do this?

P.S.

• I don't want to change system settings.
• I've seen this one(http://stackoverflow.com/questions/10456/howto-disable-webbrowser-click-sound-in-your-app-only) but Document.Write is not an option for me.

Answer 1

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.

Answer 2

Your only other option is to mute the computer, but that's hardly a good idea...

Answer 3

So this is known limitation then...

Is there any dirty hack / workaround such as hooking sound calls of the ActiveX and disabling them (Not sure if it's possible without going too deep)

Answer 4

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);

Answer 5

I cant make it work on VB.net, tried this:

Private Const FEATURE_DISABLE_NAVIGATION_SOUNDS As Integer = 21
Private Const SET_FEATURE_ON_THREAD As Integer = &H1
Private Const SET_FEATURE_ON_PROCESS As Integer = &H2
Private Const SET_FEATURE_IN_REGISTRY As Integer = &H4
Private Const SET_FEATURE_ON_THREAD_LOCALMACHINE As Integer = &H8
Private Const SET_FEATURE_ON_THREAD_INTRANET As Integer = &H10
Private Const SET_FEATURE_ON_THREAD_TRUSTED As Integer = &H20
Private Const SET_FEATURE_ON_THREAD_INTERNET As Integer = &H40
Private Const SET_FEATURE_ON_THREAD_RESTRICTED As Integer = &H80

Declare Function CoInternetSetFeatureEnabled Lib "urlmon.dll" ( _
ByVal FeatureEntry As Integer, ByVal dwFlags As Long, _
ByVal fEnable As Long) As Long

...

CoInternetSetFeatureEnabled(FEATURE_DISABLE_NAVIGATION_SOUNDS, SET_FEATURE_ON_PROCESS, True)

Edit: Found the problem, its within declaring. True one is:

<SecurityCritical, SuppressUnmanagedCodeSecurity, DllImport("urlmon.dll", ExactSpelling:=True)> _
Public Shared Function CoInternetSetFeatureEnabled(ByVal featureEntry As Integer, ByVal dwFlags As Integer, ByVal fEnable As Boolean) As Integer
End Function

Answer 6

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.
