Замена стандартного WebBrowser C#

Как я понял, стандартный элемент WebBrowser базируется на IE 7.0. Некорректно отображается нужный мне сайт. Можно ли обновить его хотя бы до 11 версии? Или существуют ли сторонние библиотеки/фреймворки как альтернатива?

Ответ

WebBrowser базируется на текущем IE, но он принудительно запускается в режиме совместимости с IE7.
Решение - перед инициализацией контрола вписать в реестр по пути Software\Microsoft\Internet Explorer\Main\FeatureControl\myapp.exe ключ FEATURE_BROWSER_EMULATION со значением, соответствующим нужной версии браузера. Полный код для приведения WebBrowser в нормальный рабочий вид выглядит так:
private void SetBrowserFeatureControlKey(string feature, string appName, uint value) { using (var key = Registry.CurrentUser.CreateSubKey( String.Concat(@"Software\Microsoft\Internet Explorer\Main\FeatureControl\", feature), RegistryKeyPermissionCheck.ReadWriteSubTree)) { key.SetValue(appName, (UInt32)value, RegistryValueKind.DWord); } }
private void SetBrowserFeatureControl() { // http://msdn.microsoft.com/en-us/library/ee330720(v=vs.85).aspx
// FeatureControl settings are per-process var fileName = System.IO.Path.GetFileName(Process.GetCurrentProcess().MainModule.FileName);
// make the control is not running inside Visual Studio Designer if (String.Compare(fileName, "devenv.exe", true) == 0 || String.Compare(fileName, "XDesProc.exe", true) == 0) return;
SetBrowserFeatureControlKey("FEATURE_BROWSER_EMULATION", fileName, GetBrowserEmulationMode()); // Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode. SetBrowserFeatureControlKey("FEATURE_AJAX_CONNECTIONEVENTS", fileName, 1); SetBrowserFeatureControlKey("FEATURE_ENABLE_CLIPCHILDREN_OPTIMIZATION", fileName, 1); SetBrowserFeatureControlKey("FEATURE_MANAGE_SCRIPT_CIRCULAR_REFS", fileName, 1); SetBrowserFeatureControlKey("FEATURE_DOMSTORAGE ", fileName, 1); SetBrowserFeatureControlKey("FEATURE_GPU_RENDERING ", fileName, 1); SetBrowserFeatureControlKey("FEATURE_IVIEWOBJECTDRAW_DMLT9_WITH_GDI ", fileName, 0); SetBrowserFeatureControlKey("FEATURE_DISABLE_LEGACY_COMPRESSION", fileName, 1); SetBrowserFeatureControlKey("FEATURE_LOCALMACHINE_LOCKDOWN", fileName, 0); SetBrowserFeatureControlKey("FEATURE_BLOCK_LMZ_OBJECT", fileName, 0); SetBrowserFeatureControlKey("FEATURE_BLOCK_LMZ_SCRIPT", fileName, 0); SetBrowserFeatureControlKey("FEATURE_DISABLE_NAVIGATION_SOUNDS", fileName, 1); SetBrowserFeatureControlKey("FEATURE_SCRIPTURL_MITIGATION", fileName, 1); SetBrowserFeatureControlKey("FEATURE_SPELLCHECKING", fileName, 0); SetBrowserFeatureControlKey("FEATURE_STATUS_BAR_THROTTLING", fileName, 1); SetBrowserFeatureControlKey("FEATURE_TABBED_BROWSING", fileName, 1); SetBrowserFeatureControlKey("FEATURE_VALIDATE_NAVIGATE_URL", fileName, 1); SetBrowserFeatureControlKey("FEATURE_WEBOC_DOCUMENT_ZOOM", fileName, 1); SetBrowserFeatureControlKey("FEATURE_WEBOC_POPUPMANAGEMENT", fileName, 0); SetBrowserFeatureControlKey("FEATURE_WEBOC_MOVESIZECHILD", fileName, 1); SetBrowserFeatureControlKey("FEATURE_ADDON_MANAGEMENT", fileName, 0); SetBrowserFeatureControlKey("FEATURE_WEBSOCKET", fileName, 1); SetBrowserFeatureControlKey("FEATURE_WINDOW_RESTRICTIONS ", fileName, 0); SetBrowserFeatureControlKey("FEATURE_XMLHTTP", fileName, 1); }
private UInt32 GetBrowserEmulationMode() { int browserVersion = 7; using (var ieKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer", RegistryKeyPermissionCheck.ReadSubTree, System.Security.AccessControl.RegistryRights.QueryValues)) { var version = ieKey.GetValue("svcVersion"); if (null == version) { version = ieKey.GetValue("Version"); if (null == version) throw new ApplicationException("Microsoft Internet Explorer is required!"); } int.TryParse(version.ToString().Split('.')[0], out browserVersion); }
UInt32 mode = 11000; // Internet Explorer 11. Webpages containing standards-based !DOCTYPE directives are displayed in IE11 Standards mode. Default value for Internet Explorer 11. switch (browserVersion) { case 7: mode = 7000; // Webpages containing standards-based !DOCTYPE directives are displayed in IE7 Standards mode. Default value for applications hosting the WebBrowser Control. break; case 8: mode = 8000; // Webpages containing standards-based !DOCTYPE directives are displayed in IE8 mode. Default value for Internet Explorer 8 break; case 9: mode = 9000; // Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode. Default value for Internet Explorer 9. break; case 10: mode = 10000; // Internet Explorer 10. Webpages containing standards-based !DOCTYPE directives are displayed in IE10 mode. Default value for Internet Explorer 10. break; default: // use IE11 mode by default break; }
return mode; }
public Form1() { // до создания контрола SetBrowserFeatureControl();
