I've created a couple of Office plugins. The plugin shows a set of html files installed on the clients computer. The plugin uses a COM-accessible assembly which shows a WinForm with a WebBrowser on it. The plugin makes the WebBrowser navigate to a file on the clients computer. The assembly is also used in other programs to show the same information.
When showing the local html files using a 'normal' browser (e.g. double clicking a file in Windows Explorer) the browser popup a security warning about running active content. This is because we have some javascript in it. This warning is supressed by setting the 'Allow active content to run in files on My Computer' in the Internet Explorer settings. This solves the issue using a 'normal' browser.
Funny enough the 'active content' warning is not shown when getting the same file using a Word/Excel/PowerPoint plugin. It calls the same assembly, using the same WinForm and using the same content. Despite the setting 'Allow active content to run from My Computer' being false, the content is shown without a warning and the javascript is executed.
Now, the problem and the real question is that Outlook does the reverse. No matter what I use for 'Allow active content to run from My Computer' the browser warning about the active content in the html file is shown. When I confirm the message and allow the scripts to continue, the javascript runs fine. So, even when I set the 'Allow active content to run from My Computer' to true, the warning is given.
I've gone through all (sort of) relevant settings in Outlook, but nothing helps.
I assume that Outlook is using some kind of private context for a webbrowser (probably because it is using a webbrowser object internally).
The real question is: how can I make the Outlook plugin respect the IE settings?
(I understand this is a long story and maybe not clear enough. Please let me know if I have to elaborate more).
I couldn't get rid of the security warning without lowering the security setting. And that is not an option: we are talking about a project that will be installed on millions of computers.
I decided to go another route. Let's see if we can make the browser trust the html pages. So, what to do to get rid of the 'Active content' warning.
First I investigated what exactly triggers the warning. That was easy: any tag in your html file will do. And I need script, so removing that isn't an option. But, when hosted from a website, the scripts run fine and don't suffer from a warning. So, I investigated if it is possible to run my files in the Internet-context.
I found out there is a way, at least for IE (which in my case is sufficient). If you save a webpage as a complete HTML file from IE, the browser adds a comment to the html to signal its origin. Something like: . If you later open that stored html file, the file is shown in the Internet context.
So, I tried adding to the html file. And, voila, the file is opened in the Internet context. The security warning about active content is gone and the scripts are executed fine.
But, that raised another problem. We have a couple of window.open statements in the scripts and using that causes he cross domain browsing problems that in recent IE versions are blocked. Even if you use a relative path in the window.open call, if fails and you end up with a blank window.
In our case, we can (probably) decide to get rid of the window.open calls. But, if a reader ever finds a solution for using window.open in this scenario, I would be very happy if you let me know.
So, for now: case closed...
Internet explorer use Mark of web in such cases

I have a complex HTML5 based user interface, which I show in my native win32 desktop application using webbrowser (Internet Explorer).
I've decided to open it from local machine instead of web server. But it did not work due to various security restrictions. So I found a workaround: setup asynchronous pluggable protocol for https protocol inside of my process and just provide data from local machine instead of Internet. I had to also implement my custom IInternetSecurityManager for the things to work (for unknown reason it was not enough to just implement IInternetSecurityManager and use file: scheme).
Now all seems to work fine except the one thing: browser completely ignores CSS files. It acts the way as if files are not there. It loads js from files, shows images, but does not "see" CSS files.
If I try to navigate to CSS file, it shows me this error message:
But if I try to access this CSS file using XMLHttpRequest - it "downloads" it fine.
Sorry for not providing a minimal reproducible example - it would be quite hard. Maybe somebody knows the reason, or can suggest me anything that I could try to resolve this issue?
When I am trying to upload a file using ieframe in IE9<, am getting the error in developer tools:
HTML1113: Document mode restart from IE9 Standards to Quirks
Hence the upload status is not displayed. I tried using meta tag <meta http-equiv="X-UA-Compatible" content="IE=8"> but it's still not working.
Can any one throw some light on it.
According the IE11 console error reference:
"HTML1113: Document mode restart from [mode] to [mode]
The webpage requires a different document mode than the browser was
currently set to.
This message can occur when the user browses from another page, so it can be out of the developer's control."
Given your description, it sounds like your child frame is embedded within a larger document. If that's the case, verify that the document modes of both document are consistent. If one requires standards mode, the other should be using it as well.
For best results, use the HTML5 doctype (<!DOCTYPE html>) for all documents; this will trigger standards mode (or edge mode, as it's now called) in each version of IE. If you're not able to do this, then you may wish to try opening the framed document in a new window, rather than embedding it on a parent document.
Hope this helps...

I'm running Selenium in singleWindow mode and IE8.
If i start IE8 manually the IE8 mode is set, but when i launch it with Selenium, the mode set is IE7 using the compatibility mode.
Anyone knows why the compatibility mode is not the IE8 view when launching the browser with Selenium?
Or, how can i disable totally the compatibility mode in IE and force it to use always the IE8 view?
I've given the question a +1 because it's a very good question -- it's not obvious how to do this, and if you need to test both modes, then it is a necessary thing to do.
You could get the site to serve <meta http-equiv="X-UA-Compatible" content="IE=7" /> within the page when running the tests. This should force the output mode.
Obviously, that's not ideal, because it means changing your code to produce the meta tag on demand. I'd normally consider it a bad thing if you're having to change the main codebase in to add code for the specific use of your test suite, but in this case I can't see any other solution.
Given that we've decided to go down this path, you could write your code to accept a specified argument in the URL that triggers the meta tag to be served. The IE7 tests could then be written to send that URL argument.
By the way, it's worth pointing out that IE8's IE7-compatibility mode is not 100% identical to IE7; it has its own quirks and bugs which are distinct from those of a real IE7 browser. For the most part it should be fine, but it's worth being aware of this if you're expecting your tests to confirm that the site works in IE7. See this blog post for more info
I have some workarond solution for this, I use it regularly:
In internet explorer goto:
1. Tools / Compatibility view settings.
2. At the Add website input textbox add your website url.
Hope that helps, best regards,

Currently I'm trying to include Dojo from either one of these two CDN (Content Delivery Network) sources:
1) o.aolcdn.com/dojo/1.3.2/dojo/dojo.xd.js
2) ajax.googleapis.com/ajax/libs/dojo/1.3.2/dojo/dojo.xd.js
It seems like some times during the day, Firefox 3.5 refuses to load the dojo library.
I see errors in Firebug console like "dojo is not defined" when I do a "dojo.require" statement. Also from Firebug and go to the "Net" tab, and see no history of any attempt to load from the above dojo libs.
Yet, I can open the same page in IE7 and it works. I have flushed cache in FireFox, and killed and re-opened it (but I was using the restore previous pages option).
One time today, when I switched from AOL 1.3.2 to 1.1 it worked once, then never has worked again.
Thanks,
Neal
Sounds like timing issues. Are you sure you do CDN right? The trick is you cannot use what's defined in files you dojo.require()d right away — they are going to be loaded asynchronously.
The basic structure of the CDN-based application is like this:
<script src="to/dojo/cdn"></script>
<script>
dojo.require("dojo.this");
dojo.require("dojo.that");
// more dojo.require()
// you cannot use dojo.this and dojo.that here
dojo.addOnLoad(function(){
// this is crucial: do everything in dojo.addOnLoad();
// now use dojo.this and dojo.that
dojo.this(dojo.that);
});
</script>
In order to troubleshoot you can do one thing: write a minimal web page, which loads Dojo using your favorite CDN and does nothing. Open it up in Firefox, open Firebug and enter some simple Dojo calls manually to see if it works for you. If it doesn't, switch to the Net tab and see what calls were made, when, and how they ended.
It looks like IE7 doesn't reload the latest version of my stylesheet each time I upload a new version on the server.
This is annoying as I am debugging my .css file to make it work on IE...
Tried to empty the browser cache but still not working.
Thanks for your help.
Ctrl-F5 - forcible way to reload in IE
Include your version number in the file name. myfile_v1234.css
When testing, every time you do an update you can just wite "stylesheet.css?r=98123"
As long as the query string is different, it'll be downloaded again.
If you need, you can use javascript to append Math.random(), to get the random number. Not required on production though, when updates would be stable.
2 Questions:
Does IE eventually load with the newer stylesheet?
How are you saving the changes to the server (SSH, Web Interface, etc.)?
I ask because I ran into an issue with a web-based file management system a while back where one browser would show the CSS just fine, the other wouldn't, and we noticed the issue of which browser played nicely depended on which browser we used to upload the CSS.
The reason turned out to be that IE gave the CSS file a different MIME type than Firefox. If you continue to notice the issue even when you've cleared the cache, check the MIME type of the file using Firefox by going to Tools > Page Info.
Also, if it is simply a caching issue, consider turning caching off in IE. I believe this should be an Advanced Option under Internet Options.
Also, you may want to try creating a special developer environment for IE (if it comes down to it.) Perhaps have another machine with IE7 and no caching and any other features turned off (A kiosk mode, perhaps), and then previewing the page on that machine.
Thanks to you all!
I did manage to solve my problem with the "stupid" Ctrl+F5, and by changing the Internet Parameters of Windows to reload content every new visit.
