仿真时 WPF WebBrowser 控件的问题 >IE7 [英] Issue With WPF WebBrowser Control When Emulation > IE7

问题描述

我有一个 C#/WPF 应用程序，它使用一个 WebBrowser 控件，该控件将一个网站作为它的主要界面(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 IE7 以上(使用下面的代码).当我对本机方法进行 javascript 调用时不会被调用，除非我从 'http://localhost' 运行网站美好的.

I have a C#/WPF application that uses a WebBrowser control that presents a website as it's primary interface (for a kiosk). The website can call a C# method via javascript for some native processing. Everything works fine until I set the 'FEATURE_BROWSER_EMULATION' above IE7 (using the code below). When I do the javascript call to the native method does not get called unless I run the website from 'http://localhost' which works fine.

我认为这是一个安全问题.我弄乱了 IE 中的所有安全设置(包括将站点设置为受信任站点")，但我似乎无法让它正常工作.

I'm assuming this is a security issue. I've messed with all of the security settings in IE (including setting the site as a 'Trusted Site'), but I can't seem to get it working.

编码我正在使用设置仿真:

Coding I'm using the set the emulation:

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 );
        }

    }

推荐答案

禁用FEATURE_LOCALMACHINE_LOCKDOWN、FEATURE_BLOCK_LMZ_SCRIPT、FEATURE_BLOCK_LMZ_OBJECT 功能.您可以从此处调整工作的 C# 代码.或者，我相信您可以使用 "Web 标记" 使您的脚本再次运行.

Disable FEATURE_LOCALMACHINE_LOCKDOWN, FEATURE_BLOCK_LMZ_SCRIPT, FEATURE_BLOCK_LMZ_OBJECT features. You can adapt the working C# code from here. Alternatively, I believe you can use "Mark of Web" to make your scripts run again.
