如何使WebBrowser控件显示现代内容？ [英] How can I get the WebBrowser control to show modern contents?

问题描述

我创建了一个使用WebBrowser控件的Winforms应用；我动态分配了它的Uri。它工作了一段时间，但是现在我得到了这个消息：

您似乎正在使用不受支持的浏览器。旧版的浏览器可能会危及您的安全，运行缓慢，并且无法使用新版的Google Maps功能。要访问Google地图，您需要更新为现代浏览器。

最后两个词是一个链接，在该链接之后，我看到了：

您当前正在使用...
IE 11

好吧，WebBrowser组件使用IE 11；我该如何更改呢？

我的机器设置为使用Chrome作为其浏览器；控件应该使用您当前使用的浏览器是什么？我不知道这是否可能/可行。

UPDATE

好吧，我愿意Reza的建议尝试一下。但是，当我导航到regedit中的指定位置并在右窗格中右键单击以添加新条目时，它具有三个选项：

键，字符串值，二进制值

我认为字符串值是 .exe字符串，二进制值是 dword值，但是 Key值应该是什么？

解决方案

Web浏览器控件

在上述步骤中，我使用了 11001 ，即IE11 Edge模式。

对Windows窗体使用WebViewCompatible控件

您还可以使用新的适用于Windows窗体的WebViewCompatible控件。您可以在此处看到使用简单的步骤：用适用于Windows窗体的新WebView兼容控件替换WebBrowser控件。

WebViewCompatible 使用两个渲染引擎之一来支持更广泛的Windows客户端集：

• 在Windows 10设备上，较新的Microsoft Edge渲染引擎用于嵌入视图，以渲染来自远程Web服务器，动态生成的代码或内容文件的格式丰富的HTML内容。




• 在运行旧版Windows的设备上，使用System.Windows.Controls.WebBrowser，它提供基于Internet Explorer引擎的呈现。

设置X-UA兼容元标记

您可以访问页面的html内容，并且可以更改内容（例如，它是本地html文件或网站属于您自己），然后可以设置 X- 头中的UA兼容 元标记，例如：< meta http-equiv = X- UA兼容 content = IE = Edge /> 。

使用其他浏览器控件

您可以依赖其他浏览器控件，例如 CefSharp 。

I've created a Winforms app that uses a WebBrowser control; I dynamically assign its Uri. It worked fine for awhile, but now I'm getting this msg:

You seem to be using an unsupported browser. Older browsers can put your security at risk, are slow and don't work with newer Google Maps features. To access Google Maps, you'll need to update to a modern browser.

The last two words are a link, and following that link, I see:

You are currently using... IE 11

So, okay, the WebBrowser component uses IE 11; how can I change that?

My machine is set to use Chrome as its browser; perhaps the control should use whatever your current browser is? I don't know if that's possible/feasible.

UPDATE

Okay, I'm willing to give Reza's suggestion a try. But when I navigate to the specified spot in regedit, and right-click in the right pane to add a New entry, it has three options:

Key, String Value, Binary Value

I reckon the string values are the ".exe" strings, and the Binary values are the "dword" vals, but what should the "Key" values be?

解决方案

WebBrowser Control

The WebBrowser control uses the same Internet Explorer version which is installed on your OS but it doesn't use the latest document mode by default and shows content in compatibility mode.

Symptom - As a symptom, the site works properly in Internet Explorer or other browsers, but WebBrowser control doesn't show the site well and for some sites it shows script errors.

Solution - You can tell the WebBrowser control to use the latest document mode without compatibility mode in WebBrowser control. You can follow instructions here to disable the setting using registry. _{[Reference: Browser Emulation]}

Apply Browser Emulation setting using code

If you want to apply the settings using code, run the following code once:

using (var key = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(
    @"Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION",
    true))
{
    var app = System.IO.Path.GetFileName(Application.ExecutablePath);
    key.SetValue(app, 11001, Microsoft.Win32.RegistryValueKind.DWord);
    key.Close();
}

In above code, I've used 11001 which means IE11 Edge mode.

Internet Explorer 11. Webpages are displayed in IE11 edge mode, regardless of the declared !DOCTYPE directive. Failing to declare a !DOCTYPE directive causes the page to load in Quirks.

Apply the Browser Emulation setting manually

Open Registry editor and browse HKEY_CURRENT_USER, go to the following key:

Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

Add the following values:

"YourApplicationFileName.exe"=dword:00002af9
"YourApplicationFileName.vshost.exe"=dword:00002af9

(In older versions of Visual Studio you needed to add vshost.exe value as well, when you run your program in Visual Studio.)

To create entries right click on an empty area of the right pane, then in the window which appears after selecting dword value, choose hexadecimal and enter 2af9:

In above steps, I've used 11001 which means IE11 Edge mode.

Use WebViewCompatible Control for Windows Forms

You can also use the new WebViewCompatible control for Windows Forms. You can see simple steps to use here: Replace WebBrowser control by new WebView Compatible control for Windows Forms.

WebViewCompatible uses one of two rendering engines to support a broader set of Windows clients:

• On Windows 10 devices, the newer Microsoft Edge rendering engine is used to embed a view that renders richly formatted HTML content from a remote web server, dynamically generated code, or content files.

• On devices running older versions of Windows, the System.Windows.Controls.WebBrowser is used, which provides Internet Explorer engine-based rendering.

Set X-UA-Compatibile meta tag

In case that you have access to the html content of the page and you can change the content (for example it's a local html file, or the site belong to yourself) then you can set X-UA-Compatibile meta tag in the head like: <meta http-equiv="X-UA-Compatible" content="IE=Edge" />.

Use other Browser Controls

You can rely on other browser controls like CefSharp.
