我正在开发一个使用IWebBrowser2嵌入式控件的winapi C++程序。IWebbrowser2 IE =边缘和用户代理字符串

我运行Windows 7 + IEXPLORE 11,所以当我打开IE11和呼叫到我的服务器我得到这个用户代理字符串:

Mozilla/5.0 (Windows NT 6.1; Trident/7.0; rv:11.0) like Gecko 

当从IWebBrowser2的发出请求我得到这个UA字符串:

Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; Tablet PC 2.0; InfoPath.3; .NET4.0E) 

我已经设法此meta标签附加到的IWebBrowser2加载的每一个html页面(编辑试图避免做浏览器功能控制 - 参见评论 - ):

<meta http-equiv="X-UA-Compatible" content="IE=edge"/> 


第一个问题:通过这样做,我启用了最新安装的IEXPLORE版本的功能?

第二个问题:我在Changing the user agent of the WebBrowser control中看到如何更改IWebBrowser2中的UA字符串。

有没有什么办法在安全的用户权限中获取最新的IE版本的UA字符串? (所以即使对于我可以实现的大多数权限受限的用户帐户)。 我试着ObtainUserAgentString()没有运气,总是让"Mozilla/4.0 ... MSIE 7.0 ..."

**第一个问题**:您需要实现浏览器功能控制:http://stackoverflow.com/a/18333982/1768303,**第二个问题**,不知道我完全理解你在问什么,但希望第一个人也修复它。 – Noseratio

谢谢,@Noseratio。浏览器FC需要将一些密钥写入注册表中。我不是Windows安全专家,但我认为这可能需要用户帐户权限,这是我试图通过'IE = edge'来避免的。我的第一个问题是关于这是否与浏览器FC具有相同的效果。也许我错了,不需要帐户权限?我将澄清 – Miquel

问题'HKEY_CURRENT_USER'不需要任何管理权限。 – Noseratio

最后,感谢Noseratio评论(+1),我实现了浏览器的功能控制,因为这并不需要管理员权限。我还在注册表中将密钥打开为易失性,以便在可能的卸载后不会让注册表脏了。

正如Noseratio reffers到C#联的反应,我离开这里的C++翻译,如果有人的解释需要它了每个功能是这样做的:

static bool SetBrowserFeatureControlKey(wstring feature, wchar_t *appName, DWORD value) { 
    HKEY key; 
    bool success = true; 
    wstring featuresPath(L"Software\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\"); 
    wstring path(featuresPath + feature); 

    LONG nError = RegCreateKeyEx(HKEY_CURRENT_USER, path.c_str(), 0, NULL, REG_OPTION_VOLATILE, KEY_WRITE, NULL, &key, NULL); 
    if (nError != ERROR_SUCCESS) { 
    success = false; 

    } else { 
    nError = RegSetValueExW(key, appName, 0, REG_DWORD, (const BYTE*) &value, sizeof(value)); 
    if (nError != ERROR_SUCCESS) { 
     success = false; 
    } 

    nError = RegCloseKey(key); 
    if (nError != ERROR_SUCCESS) { 
     success = false; 
    } 
    } 

    return success; 
}

    ZeroMemory(fileName, (MAX_PATH + 1) * sizeof(wchar_t)); 
    wstring exeName = String2wstring(splittedFileName.at(splittedFileName.size() - 1));
