WPF WebBrowser 控件 - 如何抑制脚本错误?

问题描述

我在这里发现了一个类似的问题:

I found a similar question here:

如何抑制脚本使用 WPF WebBrowser 控件时出错?

但是这些解决方案都不适合我.我需要阻止弹出窗口出现，因为我正在使用 WebBrowser 在网站上自动执行管理任务.

But non of those solutions work for me. I need to stop the popups from appearing as i am using the WebBrowser to automate admin tasks on a website.

SuppressScriptErrors 似乎不是我的 WebControl 上的可用属性 :(

SuppressScriptErrors does not appear to be an available attribute on my WebControl :(

推荐答案

这是一个 C# 例程，它能够将 WPF 的 WebBrowser 置于静默模式.你不能在 WebBrowser 初始化时调用它，因为它太早了，而是在导航发生之后.这是一个带有 wbMain WebBrowser 组件的 WPF 示例应用:

Here is a C# routine that is capable of putting WPF's WebBrowser in silent mode. You can't call it at WebBrowser initialization as it 's too early, but instead after navigation occured. Here is a WPF sample app with a wbMain WebBrowser component:

public partial class Window1 : Window
{
    public Window1()
    {
        InitializeComponent();
        wbMain.Navigated += new NavigatedEventHandler(wbMain_Navigated);
    }

    void wbMain_Navigated(object sender, NavigationEventArgs e)
    {
        SetSilent(wbMain, true); // make it silent
    }

    private void button1_Click(object sender, RoutedEventArgs e)
    {
        wbMain.Navigate(new Uri("... some url..."));
    }
}


public static void SetSilent(WebBrowser browser, bool silent)
{
    if (browser == null)
        throw new ArgumentNullException("browser");

    // get an IWebBrowser2 from the document
    IOleServiceProvider sp = browser.Document as IOleServiceProvider;
    if (sp != null)
    {
        Guid IID_IWebBrowserApp = new Guid("0002DF05-0000-0000-C000-000000000046");
        Guid IID_IWebBrowser2 = new Guid("D30C1661-CDAF-11d0-8A3E-00C04FC9E26E");

        object webBrowser;
        sp.QueryService(ref IID_IWebBrowserApp, ref IID_IWebBrowser2, out webBrowser);
        if (webBrowser != null)
        {
            webBrowser.GetType().InvokeMember("Silent", BindingFlags.Instance | BindingFlags.Public | BindingFlags.PutDispProperty, null, webBrowser, new object[] { silent });
        }
    }
}


[ComImport, Guid("6D5140C1-7436-11CE-8034-00AA006009FA"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
private interface IOleServiceProvider
{
  [PreserveSig]
  int QueryService([In] ref Guid guidService, [In] ref Guid riid, [MarshalAs(UnmanagedType.IDispatch)] out object ppvObject);
}
