I'm using a System.Windows.Forms.WebBrowser control to load a webpage. My understanding is it is just a wrapper around Internet Explorer. I'm therefore struggling to understand why the web page loads ok in a desktop browser (IE 11) but not in the browser control.
The URL has looks as so:
http://subdomain.domain.co.uk/?argumentName=argumentValue
My question is, firstly, is that a valid url (format wise)? Can you have a '?' directly after the '/' as shown? My theory is this could be getting removed behind the scenes when using a desktop browser and not happening when using the browser control. Unfortunately I cannot test that theory as the web page is behind a firewall. At the moment I know nothing else about the location of the web page other than the url.
If that is a valid url, could anyone suggest reasons it would load in IE but not in the web browswer control?
To expand on how its not working, the request times out after 30 seconds. The NavigateError event is raised (status code for me is -2146697211, but that could well be different to status code they get. I cannot find that out until I deploy a dll with some logging info).
The webpage then displays as

I'm trying to navigate my WebBrowser inside my Windows Form Application to a website that uses Cloudflare.
Here is the code I'm using:
webBrowser1.Navigate("WEBSITE URL");
But when the webBrowser1 navigates to the site it get stuck on this site from Cloudflare and does not redirect to the website
Checking your browser before accessing www.WEBSITE.COM
This process is automatic. Your browser will redirect to your requested content shortly.
Is there a way to stop the webBrowser1 from getting stuck here?
I created a program in c# with webbrowser control that opens a web site and the user will be automatically logged in. That works. However the user should also browse through different web site sections and that's where I get a problem. There is a button on one page "print preview" and what it does in "normal browser" (IE or Mozilla) it opens a new tab and shows the contents. In my program it opens Internet Explorer (it is the default browser) and shows me login page again. Can anyone explain how to open a new tab in my webbrowser control (or new window) and pass login data.
Thank you.
It can't be done the way you are trying to do it. There is no concept of tabs in the web browser control. You can verify this by loading up an html page that makes calls to window.open() in javascript. If that call is made it will just launch an instance of IE that navigates to that particular URL.
Your best bet is to have multiple web browser controls and pass data between them. Either that or use HttpWebRequest.
Although, depending on what you are trying to do you may want to automate IE instead.
I host angular component what works as a map.
There is a search feature that is a text box that returns the list of strings:
It works fine when it runs on browser, but it doesn't when I run it in cef browser component.
There are request-response sequence from browser application that works fine:
There are request-response sequence from WPF Cef applications:
I believe that some configuration is missing for Cefsharp implementation. I tried all of things like "disable cache" etc., but it was all to no avail.
Additionally, for browser application that works, Security section shows "This page is not secure.":
Whereas for Cef application it is 'The security of this page is unknown.":
My react application runs from localhost, whereas application in cefsharp runs from embedded resource:
http://app//resource/BrowserEx.ViewModels/web-gis-app/build/common-components/cc-gis-viewer/index.html?
When I run the html file directly on browser on double click it throws exception:
I will appreciate any advice, suggestion or even hint.
I finally found the reason by analyzing of my request-response URLs by Fiddler.
My URL in Cefsharp was incorrect.
Once I held my URLs in App.config file and config file doesn't like "&":
Here I found the solution for the issue.
The solution was just to remove all amp; characters:
Hence, conclusion of all this mishmash: don't use & while building your URL, - use & instead!
With WebClient.DownloadString method it's fairly simple to load normal web page source to string.
But is there any easy way to load those pages which extends and loads new content when you scroll down to end?
You cannot "download" such a page, as it doesn't exist in full form. Such pages require user interaction.
You can use one of the forms of the WebBrowser control to browse to, and programmatically interact with a web site.
hey you can try this approach if you want to do it webclient..
See here.. basically he is using the scrapy but this approach can be adopted in case of webclient to i think so.
basically he is using the firebug or chrome developer tool in order to trace the ajax web request after knowing the web request you can get the content with webclient.
I want to get the URL from all open tabs. I have searched on Google but could not find any luck. I want to read and log the URL from all open tab from Chrome And IE.
I am using C# windows form application.
Thanks in Advance..

I understand what you need to do but I would be surprised if IE and Chrome would expose the tabs and the urls in a simple and similar way to external applications, I think the way to go is to build a Chrome extension and an IE plugin or Addin to get those information while running within the browser scope, then you can send this info to an external application or to a web service etc... you will find a way to get the info out once you have got this url list inside your own code running with the browser.
see here for some starting point / ideas
