IE中Adobe Flash Player的神秘错误0x270f：实用解决方案分享。

WebBrowser脚本错误的原因及Web Browser Control & Specifying the IE Version
实际是IE打开版本的问题
WebBrowse默认打开IE7.0的版本
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.

最近想用 WebBrowser控件实际打开发生报错

解决方案一（手动修改注册表）

32位系统运行32位程序或64位系统运行64位程序，在这里修改：

代码实现更改IE版本（注册表）
