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.

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've a C# WPF application developed in VS 2015, and I want the browser to read some data from it. Just a short string. I can save it in a text file, or in a variable but it should be visible to the browser (using JS I suppose). For instance using file:/// doesn't work if the original page is hosted online - as in my case (different source conflict). This should work in Opera and FFox, but looking at their extensions, it seems you can only develop with front-end technologies, which are not enough in my case since I use WPF to look into Win OS, and then I need to share the result with the browser.
I suspect it's possible, and no , it's not to write a malicious piece of code. For instance I can read the details of the graphic card for diagnostic purposes.
Please help, many thanks.
Browsers run in a security sandbox which is intended to stop them reading or writing files to the file system.
You could write to the user's appdata. There are various javascript frameworks which persist data to there so they can provide offline or static data.
I don't think that is a good plan though.
I suggest your first candidate would be a cookie.
Quick google on how to do that, I find:
How to create cookie in c#.net windows application?
From a web page you can use the content of a cookie dynamically. So you could change what you see in the web page after it's up and running from some process in your wpf app and do a counter or whatever.
I've not used this with windows apps and a browser but I have with a web app and Silverlight. I'm afraid I don't have that code to hand though.
I'm creating a web browser that has an automatic loading of specific web pages, but the problem is that the browser that i created using c# in visual studio wont load javascipt, the browser that i created only load html file, but don't support java script. can anyone help me on how to add some functionality on my custom web browser that will support javascript.
WebKit DotNet is the best port of WebKit powerful browser engine into DotNetFramework.
It has nice and easy tutorials and properties and methods to customize.
It has JavaScript activated by default.
http://webkitdotnet.sourceforge.net/ is the official website.
http://webkitdotnet.sourceforge.net/basics.php is where you can find the basic tutorial
Webbrowser control is really crappy. I'm assuming you're trying to scape some kind of website. For this use HttpWebRequest instead.
If you`re trying create your own webbrowser: don't, or use Webkit or Gecko instead.
In case you're using the webbrowser control you will have to enable JavaScript in your Internet Explorer settings, because the webbrowser control is the Internet Explorer or at least the engine of it. IE has local JavaScript disabled by default, so this could be your problem. As user #user3855678 said I would recommend using Webkit etc too.
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.
