最近尝试用CSS3等一些新特性做一些页面,并在做了一些兼容处理之后,支持了IE7,但是碰到邪门的问题就是哪怕机器上的IE装的是非常新的10、11这样的版本,在使用WebBrowser查看页面时依旧会出现各种渲染和JS错误,甚至会出现崩溃的问题。比较残念的就是因为很早以前制作的桌面程序中正好使用WebBrowser 调用了这些新页面 √(─皿─)√

查阅MSDN时看到

Web browser control by default runs in compatibility mode unless you set the feature browser emulation registry key.
WebBrowser 控件默认运行在兼容性模式,除非修改注册表键值

于是我的心中真是无数的草泥马在奔腾啊

解决的方案是,在注册表

32位系统的:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

64位系统的:HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

新建一个DWORD键,
键名是你调用WebBrowser的exe的文件名
键值:
