设置 webbrowser 控件的表现形式，可以像你本机的IE浏览器一样

两种方式：

• Using the IE X-UA-Compatible Meta header
• Using Application specific FEATURE_BROWSER_EMULATION Registry Keys

 

Registry Key Location for FEATURE_BROWSER EMULATION
You can specify these keys in the registry at:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

The HKCU key is the best place to set these values because there's a single key and it can be set without admin rights, but you can also set these keys at the machine level at HKLM:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

or for a 32 bit application on a 64 bit machine:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

 

Key Name
The keyname is the EXE name of your application like:

    outlook.exe
    MarkdownMonster.exe

Values
The value specifies the IE version as follows:

The value to set this key to is (taken from MSDN here) as decimal values:

11001 (0x2AF9)
Internet Explorer 11. Webpages are displayed in IE11 Standards mode, regardless of the !DOCTYPE directive.

11000 (0x2AF8)
Internet Explorer 11. Webpages containing standards-based !DOCTYPE directives are displayed in IE11 mode.

10001 (0x2AF7)
Internet Explorer 10. Webpages are displayed in IE10 Standards mode, regardless of the !DOCTYPE directive.

10000 (0x2710)
Internet Explorer 10. Webpages containing standards-based !DOCTYPE directives are displayed in IE10 mode.

9999 (0x270F)
Internet Explorer 9. Webpages are displayed in IE9 Standards mode, regardless of the !DOCTYPE directive.

9000 (0x2328)
Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode.

8888 (0x22B8)
Webpages are displayed in IE8 Standards mode, regardless of the !DOCTYPE directive.

8000 (0x1F40)
Webpages containing standards-based !DOCTYPE directives are displayed in IE8 mode.

7000 (0x1B58)
Webpages containing standards-based !DOCTYPE directives are displayed in IE7 Standards mode. This mode is kind of pointless since it's the default.

Setting these keys enables your applications to use the latest Internet Explorer versions on your machine easily. Unfortunately there doesn't seem to be a key that says use the latest version that's installed - you have to be specific regarding the version unfortunately. Given that Windows 7 and later can run IE 11, I'm requiring users to have IE 11 if I want to use HTML5 and more advanced CSS features like Flexbox, but if your content is simpler you can probably get away with using IE 10 or even IE 9.

 

Don’t forget to add Keys for Host Environments

As mentioned above you have to specify the name of the EXE you're running as the key in the registry.

If you're using a development environment like Visual Studio or Visual FoxPro to debug your applications, keep in mind that your main EXE you are running while debugging may not be the final EXE that you are building. So after you've set up your registry keys, your debugging experience may still not see the enhanced rendering features in the Web Browser control because you're not actually running the final EXE.

The problem is that when you debug in these environments, you are running a debugging host and in order for it to render properly you may have to the host to the FEATURE_BROWSER_EMULATION keys as well.

For Visual Studio this will be yourapp.vshost.exe, which is the debugging host. For Visual FoxPro you'll want vfp9.exe. Simply add these keys to the registry alongside those you use for your actual, live application.
