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.
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.
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

We have been using Google Maps APi for 10 years via a WebBrowser control within our Windows Forms (.NET) software.
Customers tell us that it no longer works.
We understand that the .NET WebBrowser control uses Internet Explorer and cannot be changed.
We have already tried to insert the following tag, but it doesn't work.
<meta http-equiv = "X-UA-Compatible" content = "IE = edge" />
We also tried using the FEATURE_BROWSER_EMULATION registry keys, but it doesn't work.

Is there still a way to use the Google Maps API within a .NET Windows Form?
Thanks for any help
You can replace the browser control. I'm using CefSharp which is based on Chromium. Microsoft offers WebView2 which is based on its Edge Browser.
Both have a different interface than the old IE based web control and therefore require some changes to your code. How much you need to change depends on what else you do besides navigating to a Google Maps page.
Neither of the two is preinstalled on user's computers. You therefore need to add them to your application setup.
I am developing a website crawler API to scrape a javascript-generated website. The website that we are crawling requires the Javascript to be enabled to fully-render the HTML. I have tried many solutions such as HtmlAgilityPack and AngleSharp, but they are just HTML parsers and they cannot render the page due to missing Javascript capability.
I tried implementing headless browser using Selenium.WebDriver.ChromeDriver, it worked very well in my local machine. However, our production environment is very limited such that only Internet Explorer browser is available and we are not allowed to install any more browser. So this chromedriver did not work, too. Internet Explorer cannot even fully render the website from the browser itself. So IE is definitely out.
Is there a way to scrape a javascript-generated website without having to install a browser? Like implementing a headless browser on a server without that browser installed?
Or is it a dead-end situation. Thanks!
You can try using a solution that uses a fully-functional built-in Chromium and doesn't require installing Google Chrome in the target environment. All the required Chromium binaries will be shipped with the solution.
There are many such solutions for .NET and C#:
CefSharp
An open source .NET wrapper around the Chromium Embedded Framework (CEF). It allows you to embed Chromium in .NET apps.
Supported by community. If you need help with the library use, read docs or ask community. If you need a feature or a bug fix, you would probably need to do it by yourself.
DotNetBrowser
A commercial library that allows integrating a Chromium-based browser with your .NET app to display and process HTML5, CSS3, JavaScript, etc.
It's a proprietary solution supported by a commercial company. If you need help with the library use, read docs or get help from the engineers of this product. If you need a feature or a bug fix, it will be done by the product team as soon as possible. I know that, because I know the engineers from DotNetBrowser team.
WebView2
This control allows you to embed web technologies (HTML, CSS, and JavaScript) in your native apps. The WebView2 control uses Microsoft Edge (Chromium) as the rendering engine to display the web content in native apps. With WebView2, you can embed web code in different parts of your native app, or build all of the native app within a single WebView instance. Supported by Microsoft.
If you need some help, you should contact WebView2 team.
I am using system.windows.forms.webbrowser in my Win forms application with IE as my default browser. Does the IE plugin/ Patch be applicable for my WebBrowser control?
No. If you read the document you will find that system.windows.forms.webbrowser is using embedded Internet Explorer regardless of what your default browser is.
AFAIK there is no built in way to use chrome as embedded browser in win form. You need a third party lib for that.
When I try to Open google map in my C# Application, I get this error:
You seem to be using an unsupported browser. Old 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.
How can I upgrade my Browser there or How to get rid of this error?
Take a look at the approaches for upgrading IE in WebBrowser in this thread: use latest version of ie in webbrowser control
Alternatively, you can go for Chromium-based browser controls, to avoid compatibility issues. For example, here is a tutorial on embedding Google Maps using DotNetBrowser: Embed Google Maps In .NET Desktop Application.
My client WPF application needs to display an HTML page. I understand that the webbrowser control uses the version of IE that is installed on the box.
Is there a control to render HTML that can be totally embedded into my application so that it is not dependent on the version of IE, that the user has installed?
What would happed if a user is using IE6?
Thanks
You could always use WebKit .NET instead. It allows you to embed a WebKit browser in your .NET application without having to have extra software installed on the machine.
There is also geckofx if you would rather go the Mozilla Gecko route.
