仿真 > IE7 时 WPF WebBrowser 控件出现问题

Question

我有一个 C#/WPF 应用程序，它使用 WebBrowser 控件，将网站作为其主要界面（用于信息亭）。该网站可以通过 javascript 调用 C# 方法进行一些本机处理。一切正常，直到我将 'FEATURE_BROWSER_EMULATION' 设置为高于 IE7（使用下面的代码）。当我对本机方法进行 javascript 调用时，除非我运行来自“http://localhost”的网站工作正常，否则不会被调用。

我假设这是一个安全问题。我搞砸了 IE 中的所有安全设置（包括将站点设置为 'Trusted Site'），但我似乎无法正常工作。

编码我正在使用设置仿真：

private void SetBrowserCompatibilityMode()
    {
        // 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 );

        if ( String.Compare( fileName, "devenv.exe", true ) == 0 ) // make sure we're not running inside Visual Studio
            return;

        using ( var key = Registry.CurrentUser.CreateSubKey( @"Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION",
            RegistryKeyPermissionCheck.ReadWriteSubTree ) )
        {
            // Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode.
            UInt32 mode = 11000; // 11000 = IE11, 10000 = IE10, 9000 = IE9, 8000 = IE8, 7000 = IE7; 
            key.SetValue( fileName, mode, RegistryValueKind.DWord );
        }

        using ( var key = Registry.CurrentUser.CreateSubKey( @"Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_ZONE_ELEVATION",
            RegistryKeyPermissionCheck.ReadWriteSubTree ) )
        {
            // disable zone elevation prevention
            UInt32 mode = 0;
            key.SetValue( fileName, mode, RegistryValueKind.DWord );
        }

        using ( var key = Registry.CurrentUser.CreateSubKey( @"Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BLOCK_LMZ_SCRIPT",
            RegistryKeyPermissionCheck.ReadWriteSubTree ) )
        {
            // enable <scripts> in local machine zone
            UInt32 mode = 0;
            key.SetValue( fileName, mode, RegistryValueKind.DWord );
        }

        using ( var key = Registry.CurrentUser.CreateSubKey( @"Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_NINPUT_LEGACYMODE",
            RegistryKeyPermissionCheck.ReadWriteSubTree ) )
        {
            // disable Legacy Input Model
            UInt32 mode = 0;
            key.SetValue( fileName, mode, RegistryValueKind.DWord );
        }

    }

尝试以下方法之一： 1- 运行您作为管理员的程序。 2- 检查您的 JavaScript 是否与您正在模拟的版本兼容，如 IE7 上的某些 JavaScript 代码运行但不是更高版本。

更新：这是我设置仿真的方式，请注意，如果您不以管理员身份运行，此代码将无法工作：

    private static void SetIEVersioneKeyforWebBrowserControl(string appName, int ieval)
    {
        RegistryKey Regkey = null;
        try
        {
            Regkey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true);

            //If the path is not correct or 
            //If user't have priviledges to access registry 
            if (Regkey == null)
            {
                _logger.Error("Application FEATURE_BROWSER_EMULATION Failed - Registry key Not found");
                return;
            }

            string FindAppkey = Convert.ToString(Regkey.GetValue(appName));

            //Check if key is already present 
            if (FindAppkey == ieval.ToString())
            {
                _logger.Debug("Application FEATURE_BROWSER_EMULATION already set to " + ieval);
                Regkey.Close();
                return;
            }

            //If key is not present or different from desired, add/modify the key , key value 
            Regkey.SetValue(appName, unchecked((int)ieval), RegistryValueKind.DWord);

            //check for the key after adding 
            FindAppkey = Convert.ToString(Regkey.GetValue(appName));

            if (FindAppkey == ieval.ToString())
            {
                _logger.Info("Application FEATURE_BROWSER_EMULATION changed to " + ieval + "; changes will be visible at application restart");
            }
            else
            {
                _logger.Error("Application FEATURE_BROWSER_EMULATION setting failed; current value is  " + ieval);
            }
        }
        catch (Exception ex)
        {
            _logger.Error("Application FEATURE_BROWSER_EMULATION setting failed; " + ex.Message);
        }
        finally
        {
            //Close the Registry 
            if (Regkey != null) Regkey.Close();
        }
    }

并使用函数：

        var targetApplication = Process.GetCurrentProcess().ProcessName + ".exe";
        int ie_emulation = 9000;

Answer 2

禁用 FEATURE_LOCALMACHINE_LOCKDOWN、FEATURE_BLOCK_LMZ_SCRIPT、FEATURE_BLOCK_LMZ_OBJECT 功能。您可以改编 . Alternatively, I believe you can use "Mark of Web" 中的工作 C# 代码，再次制作您的脚本运行。
