Disable Sound of the WebBrowser Control

WebBrowser Control is very useful at times, but people avoid it because of the annoying IE Navigation sound it makes.

There is a way to disable navigation sounds correctly TEMPORARILY. Yes, you won't have to delete a file, or mess with a user's Registry.

Visual Basic .Net

Code:
Imports System.Runtime.InteropServices

Public Class Form1

    Private Const DISABLE_SOUNDS As Integer = 21
    Private Const SET_FEATURE_ON_PROCESS As Integer = 2

    <DllImport("urlmon.dll")> _
    Public Shared Function CoInternetSetFeatureEnabled( _
    ByVal FeatureEntry As Integer, <MarshalAs(UnmanagedType.U4)> ByVal dwFlags As Integer, ByVal fEnable As Boolean) As Integer

    End Function

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        CoInternetSetFeatureEnabled(DISABLE_SOUNDS, SET_FEATURE_ON_PROCESS, True)
        Dim web as New WebBrowser
        web.Navigate("http://www.google.com")
    End Sub
End Class

C#

Code:
private const int DISABLE_NAVIGATION_SOUNDS = 21;
private const int SET_FEATURE_ON_PROCESS = 0x00000002;


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

Usage:

Code:
CoInternetSetFeatureEnabled(DISABLE_NAVIGATION_SOUNDS, SET_FEATURE_ON_PROCESS, true);
