Scenario is simple:
If you add a web browser in visual studio it adds IE. If you are logged somewhere with IE it keeps you authenticated like reading cookies or sessions. Web browser component and IE is the same.
So, is there a way to access firefox from c# (like web browser or some way) and lets say load a page and get the html of this page? Or load a page, fill a textbox and click a button, all these via c#?
Selenium is a browser automation framework that will let you perform these tasks using C#. There's a driver for Firefox that works very well.
There is no way of using Firefox from within C# by default. You do have a few options however, if you want to do something with it's rendering engine for example you could use GeckoFX to give yourself a nice C# wrapped GECKO engine.
If it involves testing / automation then you could look into WatiN which supports various browsers or even UI automation.

I'd like to develop a software, which can start Google Chrome events (like next page, previous page, go to a specific url, open a new tab etc...) without Selenium Webdriver. It's very important!!! I don't want to use Selenium, I'd like to control existing chrome processes.
How can I do this with C# interop services?
How can I fetch JavaScript code into my chrome browser, to solve this problem?
Where can I find a tutorial about this?
Which solution is the best?
Probably it's not a too complicated problem, but I tried a ton of google search keywords already, but I haven't found anything.
You can control Chrome or any other application with UI Automation
(I use Automation Core with reference to c:\Windows\system32\UIAutomationCore.dll)
Use Inspect tool from SDK to see the hierarchy of controls and various properties
IUIAutomation::ElementFromHandle to get IUIAutomationElement from Chrome main window and so on (tested on Windows 10 in C# with Google Chrome Version 74.0.3729.169)
When am work on webBrowser control using wpf Getting error like "script error" even i pasted screen shot here and even some jquery UI and css not working
I faced this problem too. I need to create browser application which the web has lot of Jquery, JSON etc and webbrowser control does't work as expected (I'm using Windows 10 and Visual Studio 2015)
As solution, I use cefsharp.github.io which allow me to embed a full-featured standards-complaint web browser into C# or VB.NET project solution without hacking windows registry key. It based on Chromium Embedded Framework. It work like a charm!
Just grab nuget packages and create ChromiumWebBrowser class and you are ready to use it.
You have to change your WebBrowser rendering engine, by default it uses the oldest one.
In this link Microsoft describes how you can do it:
http://msdn.microsoft.com/en-us/library/ie/ee330730%28v=vs.85%29.aspx
And you can follow this good answer too.
Will the IE9 WebBrowser Control Support all of IE9's features, including SVG?
Pay attention that if you are running a 32 bit app on a 64bit system you must set this key instead
[HKLM\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION]
I tried the site that fails in your screenshot and works well with this registry change from a WebBrowser.
i am working on an winform application in which i used watiN. Now when i open my website in default winform browser control, than its design become worst. So i want to use Webkit Browser control in my winform app.
I don't know how to use Webkit Browser in watiN.
I also tried to use GeckoFX for it , but it is also not supporting in watiN.
Can anybody please tell me how can i use other browser controls in watin except Default winform browser control.
I am stucked here
Thanks in Advance
How can I launch a website in c#, and insert javascript in it?
Basically what I am doing is, I created a windows forms application with textfields that match the textfields in a website, and after filling in the fields in the forms application, it needs to open that site in a browser (with a query string that has the values in the textfields), and then insert some javascript in the DOM which will then add those values in the textfields and then invoke the click command of the submit button.
Thanks.
Omega,
You are looking for Web Browser Automation, see below:
Website Testing - Automation, Autofill, etc. (C# WinForms)
Microsoft Web Browser Automation using C#
Also see if this library helps you:
http://seleniumhq.org [never used it personally tho]
But I don't know why you want to inject JavaScript... if that is to set values of textboxes and button click, you can do it via code behind in C#... You have the Document object of AxWebBrowser or WebBrowser control in Windows Forms and you can play with it!
I hope this helps
I am building a windows forms application that I will be adding a control within that will display quite a bit of different data. For the most part the data inside will be navigation buttons and help/training text.
I think it would be ideal if I could write the contents in HTML and then just display that in the control in the application, but I am not sure if this is a good idea.
Another point to note is there will be a web based version of the same application at some point in the near future, and doing this part of the application in HTML will make for very easy reusability.
The users will not have IIS installed, if this matters.
For this purpose, I think that an embedded web browser would be absolutely great. Alot of applications use a web browser control for navigation, information, training, etc. Steam is one example. In addition, reusability is almost always a best practice.
But I would use WebKit instead of the built-in IE web browser control.
I have a similar application and I think the WebBrowser control works very well. If you think it's what you need, I would for it and there's many other applications that do something similar. You can call Javascript functions in the HTML page from C# using HtmlDocument.InvokeScript(), and C# from Javascript using window.external and having this two-way communication makes life simple.
Users do not need IIS installed as you're not running a web server, just displaying content using HTML.
I would go for the built-in IE control rather than webkitdotnet to be honest. Although WebKit itself is superior to IE, the webkitdotnet project at version 0.5 it doesn't have the C#<> JavaScript communication or DOM access and it seems hard to tell if it's still being actively developed. It'll be great if/when it gets feature parity as IE is obviously far from perfect, but the advantage of the built-in IE control is every user of your app will have it already installed and the WebBrowser control is well tested. There are some disadvantages I've found:
IE versions may range from 6 to 9, so you'll to test to make sure your content works in all (as with a website).
There's a bug in IE (at least up to 8) that relative links do not work in combination with a <base href="file://...">. This can stop you being able to use relative links in your local HTML documents.
Sometimes pages display differently inside the WebBrowser control than they do out of it. For instance, http://bugs.jquery.com/ticket/7104 is one and I've come across another similar bug affecting cufon.
For compatibility reasons, even if your users install IE > 7 the WebBrowser control will still render your content in IE7 rendering mode by default. This is different to standalone IE which renders in the most-standard mode by default, so it can catch you out if you're not expecting it. You can change this by adding <meta http-equiv="X-UA-Compatible" tag if you want, though I actually found it makes life easier as it reduces the amount of different versions you've got to test against.
