CHtmlView下的IE版本
WebBrowser与IE的关系，如何设置WebBrowser工作在IE9模式下？
修改注册表
There are two different sets of keys for 32 bit and 64 bit applications.
32 bit:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION
Value Key: yourapplication.exe
64 bit:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION
Value Key: yourapplication.exe
The value to set this key to is (taken from MSDN here) as decimal values:
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.
IE8兼容视图(IE7 mode)与独立IE7的区别
写的很详细
再谈IE的浏览器模式和文档模式
修改Htm页面的方法之一是，在Head->Title下添加<META http-equiv="X-UA-Compatible" content="IE=9" > </META>，这样可确保HTM页面工作在IE9标准文档模式下。
