如何禁用单击声音当使用C夏普web浏览器元素？

问题描述

我解雇了，当一个事件做到这一点：

I have an event when fired does this:

htmlView.DocumentText = contentArea.Text;

问题是这样的事件激发了很多，我得到了恼人的IE浏览器点击噪音。我见过一个解决方案http://stackoverflow.com/questions/10456/howto-disable-webbrowser-click-sound-in-your-app-only而另外一个，但我pretty新的C夏普（仅在使用它了几个小时），我不确定是什么：

The problem is this event is fired a lot and I get that annoying IE "click noise". I've seen a solution http://stackoverflow.com/questions/10456/howto-disable-webbrowser-click-sound-in-your-app-only and the other one, but I'm pretty new to C Sharp (only been using it for a couple of hours), and am unsure what:

---

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);

...含义。我在哪里把那个code？对不起，我用C夏普和Visual Studio，并会AP preciate帮助一个新手能理解。

...means. Where do I put that code? Sorry, I'm a noob with C Sharp and Visual Studio and would appreciate help that a neophyte could understand.

谢谢！

推荐答案

您可以把它放在一个静态类里，要么使 CoInternetSetFeatureEnabled 方法公开，或添加其他从更实用的形式，转换参数，如果需要的话后，将其称为电桥法。例如，在第一种情况下这将是：

You can put it inside a static class and either make the CoInternetSetFeatureEnabled method public, or add an additional bridge method that calls it after converting the parameters from a more usable form, if necessary. For example, in the first case it would be:

public static class UnmanagedCode
{
    private const int FEATURE_DISABLE_NAVIGATION_SOUNDS = 21;
    //etc...

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