        static void SetWebBrowserFeatures(int ieVersion)
        {
            // don't change the registry if running in-proc inside Visual Studio  
            if (LicenseManager.UsageMode != LicenseUsageMode.Runtime)
                return;
            //获取程序及名称  
            var appName = System.IO.Path.GetFileName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName);
            //得到浏览器的模式的值  
            UInt32 ieMode = GeoEmulationModee(ieVersion);
            var featureControlRegKey = @"HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\";
            //设置浏览器对应用程序（appName）以什么模式（ieMode）运行  
            Registry.SetValue(featureControlRegKey + "FEATURE_BROWSER_EMULATION",
                appName, ieMode, RegistryValueKind.DWord);
            // enable the features which are "On" for the full Internet Explorer browser  
            //不晓得设置有什么用  
            Registry.SetValue(featureControlRegKey + "FEATURE_ENABLE_CLIPCHILDREN_OPTIMIZATION",
                appName, 1, RegistryValueKind.DWord);


            //Registry.SetValue(featureControlRegKey + "FEATURE_AJAX_CONNECTIONEVENTS",  
            //    appName, 1, RegistryValueKind.DWord);  


            //Registry.SetValue(featureControlRegKey + "FEATURE_GPU_RENDERING",  
            //    appName, 1, RegistryValueKind.DWord);  


            //Registry.SetValue(featureControlRegKey + "FEATURE_WEBOC_DOCUMENT_ZOOM",  
            //    appName, 1, RegistryValueKind.DWord);  


            //Registry.SetValue(featureControlRegKey + "FEATURE_NINPUT_LEGACYMODE",  
            //    appName, 0, RegistryValueKind.DWord);  
        }
