WebBrowser webBrowser1 错误检测和内嵌浏览版本更改

错误检测，需页面加在完成后进行附加（webBrowser1_Navigated）

webBrowser1.Document.Window.Error += new HtmlElementErrorEventHandler(Window_Error);

设置默认浏览版本

public static void EnsureBrowserEmulationEnabled(string exename = "AnonymousLetter.exe", bool uninstall = false)
        {
            try
            {
                using (
                    var rk = Registry.CurrentUser.OpenSubKey(
                        @"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true)
                )
                {
                    if (!uninstall)
                    {
                        dynamic value = rk.GetValue(exename);
                        if (value == null)
                            rk.SetValue(exename, (uint)11001, RegistryValueKind.DWord);
                    }
                    else
                        rk.DeleteValue(exename);
                }
            }
            catch
            {
            }
        }
