我有一个
WPF应用程序,它使用导航窗口和框架在xaml页面之间导航.每次它在页面之间发出咔嗒声.有没有办法禁用它？
到目前为止,我试过这个：
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);
}
}
解决方法
您想要的功能称为
CoInternetSetFeatureEnabled,您可以在接受的答案
to this question中找到一些其他信息.
由于WPF在引擎盖下使用WebBrowser控件,因此它也适用于Frame控件.
