NavigationWindow Click Sound

Question

I have a WPF application that uses the navigation window and frames to navigate between xaml pages. Every time it goes between the pages it makes a click sound. Is there a way to disable that?

So far I have tried this:

namespace FrameTesting
{
public partial class MainWindow : NavigationWindow
{
    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;

    public MainWindow()
    {
        int feature = FEATURE_DISABLE_NAVIGATION_SOUNDS;
        CoInternetSetFeatureEnabled(feature, SET_FEATURE_ON_PROCESS, true);
        InitializeComponent();
    }

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

}

Answer 1

The function you want is called CoInternetSetFeatureEnabled and you can find some additional information in the accepted answer to this question .

Since WPF uses the WebBrowser control under the hood, this should work for the Frame control as well.

Answer 2

Put this on your main class:

private const int Feature = 21; //FEATURE_DISABLE_NAVIGATION_SOUNDS
private const int SetFeatureOnProcess = 0x00000002;

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

And then add this on your code (Window Loaded):

CoInternetSetFeatureEnabled(Feature, SetFeatureOnProcess, true);
