Question

I\'m using Webbrowser control to login to HTTPS site with \"untrusted certificate\". but I get popup such standart window \"Security Alert\" about untrusted certificate:

Answer 1

Here,we go with the solution: I run it on the Browser_Navigated event as the underlying activeX component is null until then.

         private void Browser_Navigating_1(object sender, NavigatingCancelEventArgs e)
        {
        HideScriptErrors(Browser,true);

        }

    public void HideScriptErrors(WebBrowser wb, bool Hide)
    {

        FieldInfo fiComWebBrowser = typeof(WebBrowser).GetField("_axIWebBrowser2", BindingFlags.Instance | BindingFlags.NonPublic);
        if (fiComWebBrowser == null) return;
        object objComWebBrowser = fiComWebBrowser.GetValue(wb);

        if (objComWebBrowser == null) return;

        objComWebBrowser.GetType().InvokeMember(
        "Silent", BindingFlags.SetProperty, null, objComWebBrowser, new object[] { Hide });

    }
