My WebBrowser Control in C# acts strange, sometimes it doesn't show any Pictures..
But I can see in Fiddler or in Proxy Server that it's loading them!
For example Stackoverflow Site:
As you can see the Stackoverflow Logo isn't there, at the side from android tag the picture is missing, and the User Avatars are missing..
But as I open the Site in IE, everything is fine.
My Registry Keys for the Browser-Emulation are on 9000 (also tried 9999)..
Of course I also cleared cache from Internet Explorer..
Any suggestions?

I'm adding an embedded reportviewer object to an existing web forms solution. In Edge and Chrome it works as desired, but in IE11, the dropdown menu goes behind the report object.
How do I fix this?
IE11
Edge
Found it.
Apparently my company uses compatibility mode for intranet sites. When I turned that off, the drop down problem went away.
This page was helpful in pointing me in the right direction.
I'm a WPF developer, i have tecknet wireless mouse with me, and it have two extra buttons.
when i click on them it navigates to-fro from history in browser.
Interestingly, it also works on Windows Explorer, Microsoft Outlook and VisualStudio. Means i can go to previously visited files or location by one button and can come to current by another button.
I tried to find, how they implement this one in their driver, so far no luck. If you guys know about this, share the information. I will use it in my next application.
Thanks,
I have a code that checks for image links and turn them into
<img src="link"></img>
My problem is, certain images from certain websites do not work. I tried re-uploading them to another image hosting server and they work. But also when I check them on IE they start appearing in my program.
It's not a CMYK problem, I think it's more of a compatibility problem or cache related.
I tried changing compatibility mode from IE7 to IE9 but the images still do not load.
I have a web browser control hosted on a WPF window so I can display html/css pages. I am having issues with my web browser control using Internet Explorer's zoom factor. The web browser control takes internet explorers zoom level to distort and mess up the way my HTML looks.
For example, if I set Internet Explorer to zoom at 150%, and the web browser will start zoomed in 150%.
I've tried using the zoom CSS property and the HTML document.style.zoom but the browser ignores my changes and takes IE's zoom. Is there a way to ignore Internet Explorer options through either my C# or overwrite them in my HTML/CSS?
Well, after searching through the internet I didn't find too many viable solutions.
I did think of a temporary workaround however. The IE zoomfactor is controlled in the registry key. Setting the registry key there controls what the web browser control sets its zoom to.
var key = "HKEY_CURRENT_USER\\SOFTWARE\\Microsoft\\Internet Explorer\\Zoom\\";
Registry.SetValue(key, "ZoomFactor", 0x186a0, RegistryValueKind.DWord); //0x1860a is 100%
I'm in a trouble trying to fix some problem.. I have a program with Webbrowser control inside it.
It automates crawling process from some website. The problem is that I cannot fix webbrowser after recent website changes.
They have changed page navigation on website. And when I do actions MANUALLY in webbrowser (in my app) it doesn't go to the next/previous page on website. It does nothing... Whereas it works properly in IE 7/8/9 (only scripting errors thrown this time).
So does it mean that Webbrowser is not fully similar to IE??
I'm sorry for not showing source codes here, I think it wouldn't help here. Which way should I go to troubleshoot it? Why page navigation is not working in Webbrowser control?
I tried to simply put Webbrowser on a Window Form in new project and tried to navigate page 2/3/../10 in the website catalog, but it simply changes page number and doesn't navigate to it...
EDIT: Website doesn't work propely even if I do actions manually in webbrowser using mouse clicks.. but works in IE.
EDIT2: I might be not clear in my question. The problem is that I cannot use website even Manually with mouseclicks via my Webbrowser control in app. It changes page number after I click on it, but it doesn't navigate to that page. It stays silent. I'm sure that AllowNavigation property is true. It worked just yesterday and stopped after website changes today... Please tell me which way should I go to troubleshoot it.. I thought that Webbrowser control acts the same way as Internet Explorer.. Any help from you highly appreciated! Thanks
EDIT3: Strange thing... i just loaded Extended Webbrowser and navigated to that website. Page navigation panel doesn't work there also.. Is it a bug on their side or some type of guard from crawlers? What do you think?

I'm sure this isn't the answer your want but using the webbrowser control to scrape websites is very painful to maintain.
Instead use the HttpWebRequest and HttpWebRepsonse objects to recreate the calls to the webserver.
You can use Fiddler (http://www.fiddler2.com/fiddler2) and your browser to record your web sessions and recreate them in code.
You can setup your webbrowser control to disable a number of features including navigation.
I.e. to disable nav in the C# WebBrowser control:
webBrowser1.AllowNavigation = false;
I'd double check that you're not doing anything like this.
I had the same issue with a certain web site that recently changed its format. It has to do with the version of IE used by the control.
Simply force the IE version used to the latest (in my case 9). Setting the appropriate registry item to 9999 for my application worked; see: Webbrowser control behaving different than IE
