I want to use IE8 as a WebBrowser control in a C# application. How can I disable "quirks mode" and force IE into standards compliance (as far as it is implemented)?
If you don't want to use the registry key technique, you could insert the following tag:
<meta http-equiv="X-UA-Compatible" content="IE=8" />
The "content" attribute forces rendering in various modes.
I think the issue you're facing is described in IEBlog: WebBrowser Control Rendering Modes in IE8:
While webmasters can easily alter
their site to render properly in the
new version of IE, many software
vendors do not have the resources to
instantly push out new versions of
their applications with updated
internal pages.
In order to ensure that these existing
applications remain in working order,
IE8 renders pages running within
instances of the WebBrowser control in
IE7 Standards Mode by default.
Here I should note that the comments on the page say the above is incorrect, and that "IE8 renders pages running within instances of the WebBrowser control in IE7 Strict Mode OR Quirks mode by default, depending on the page's doctype."
The solution is as follows:
When an executable loads an instance
of the WebBrowser control it scans the
registry to check whether the
executable wants IE7 Standards or IE8
Standards mode.
...
To run in IE8 Standards Mode insert
the following registry value:
[HKEY_CURRENT_USER\Software\Microsoft\Internet
Explorer\Main\FeatureControl\FEATURE_NATIVE_DOCUMENT_MODE]
"MyApplication.exe"=dword:13880
In both of these instances,
MyApplication.exe should be replaced
with the name of the executable that
will be running WebBrowser controls in
a specified mode.
So it sounds like the "programmatic" solution is to write a key in the registry saying you want IE8 Standards mode for WebBrowser controls in your specific application.
The last I heard was that IE8 would use standards mode by default. Are you seeing an actual problem with the latest beta version? Are you sure it's rendering in quirks mode to start with, without a user explicitly hitting the compatibility view button?
Please note there have been some changes since the beta, the registry keys have been renamed etc. Read more here.
This has actual code to programmatically do this and handles up to IE11 so far:

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.
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.
From what I know, browsers that are based on WebKit have been built around the open source webkit project after they downloaded it and built it, so if one were to build a browser around the Trident rendering engine/Internet Explorer's rendering engine, would you-
Download Trident from somewhere, build it and add it to your project, or;
Add a System.Windows.Forms.WebBrowser Control to your Form and use that?
I believe that the System.Windows.Forms.WebBrowser control is indeed based on IE's Trident engine. however it is highly limited in what it can and can't do, by default.
You can however modify application specific settings for your browser to enable features through the control.
An example of this is that the WebBrowser control, by default, renders using the lowest setting supported by the version of IE installed on the machine, so for example if you have IE9 installed, the WebBrowser control will render in IE7 compatibility mode, but you can make it render using IE9 standards based mode if you change/add some settings to the registry.
Take a look at implementing/modifying Internet Feature Controls here:
http://msdn.microsoft.com/en-us/library/ee330720%28v=vs.85%29.aspx
On another note, I think you'd be hard pushed to find a download for Trident. Being a Microsoft product, my guess is that it's a closely guarded, closed source, secret! - However of you do find a download for it, I'd be very interested to know more! :-)
Adobe does not seem to support the display of PDFs in the browser when using the 64-bit version of Internet Explorer. Once a pdf link is clicked the 64-bit Internet Explorer will always span a new Adobe window to display the pdf. The 32-bit Internet Explorer will display the pdf embedded in the browser itself.
I noticed this issue when using the WebBrowser control in a 64-bit complied WinForms .NET application. I don't believe it's possible to use the 32-bit WebBrowser control in the 64-bit application so I am looking for some solutions to this problem even if it requires the use of a third party plug-in.
Any suggestions would be greatly appreciated.
Thanks.
If you platform target needs to be x64, and your need to use an x64-incompatible feature, then clearly you have an issue. You're going to have to compromise on one side or the other.
Alternatively, you could look into opening a separate process for the PDF viewer and setting the parent window of the newly spawned process' window to your container control. This will have the effect of "embedding" the window within your control. You can then forcefully remove the border and maximize it. Windows API, to the rescue! Check out Sumatra PDF if you decide to go this route, which you can probably distribute without any trouble.
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.
