网页浏览器控制默认IE版本

Question

I have an Embedded browser in my WPF application. I have used Windows Forms Web browser control by using Windows forms host. I know that Web browser control is a wrapper around Internet Explorer Active x. Which version of IE does Web browser control takes by default. I read some where as it takes IE 6.0 and in some sites as IE 7 compatibility mode. I would also require to upgrade the version of IE in registry. Please clarify.

Answer 1

You don't really have much choice, it's whatever Internet Explorer version is installed.

In IE 8+, by default the content of a WebBrowser control is in IE7 Standards Mode, see the following IEBlog posts:

There's probably something normative in MSDN library.

Answer 2

basically is IE7. may use below javacript to check IE version

alert('IE '+document.documentMode+'\n\n'+navigator.userAgent)"

you may set the browser emulation version by registry of FEATURE_BROWSER_EMULATION.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION]
"myprogram.exe"=dword:00002af8

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION]
"myprogram.exe"=dword:00002af8
