How can I render HTML in a Silverlight 5 app? - visual-studio-2010

I'm currently working on a project that renders emails in HTML format to a Silverlight 5 app. The app is intended to be viewed via a web browser and not an 'Out of browser' app. The WebBrowser control was initially used, but I'm having issues with it. A message stating that IE needs elevated permissions and such. After reading how to properly implement the WebBrowser control by signing the .xap file and installing certificates it seems to work when I run it locally, but when I publish to the server (Windows Server 2008), it doesn't seem to work.
I tried to implement an alternative I found -> http://blogs.msdn.com/b/delay/archive/2007/09/10/bringing-a-bit-of-html-to-silverlight-htmltextblock-makes-rich-text-display-easy.aspx, but that didn't seem to work as the HTML I'm trying to render has many tags not supported in that example.
I also took a look at the Frame control http://msdn.microsoft.com/en-us/library/system.windows.controls.frame(v=vs.95).aspx but not sure if that would solve my problem either.
So if anyone can guide me into the right direction of either how I can get the WebBrowser control to work when pushed to the server or perhaps another alternative it would be greatly appreciated.

Firefox extension app hosted on server

I managed to create a Chrome extension pretty easy and the main application is hosted on my server allowing me to provide updates to the app itself without having to update the whole extension. I like the idea and I just want to know if it's possible to create a similar extension for Firefox where the main application is hosted on a live server.
In creating my Chrome extension, I followed a tutorial. The code for Chrome is included on the linked page.
It's possible to create a simple extension that loads a web app either in a panel or a tab. You should read up on the Addon SDK documentation, including the panel, tabs and getting started docs.
There is nothing wrong with this, as the web app would not have direct access to internal Firefox APIs. If you read the Addon guidelines closely that #makyen links to above, none of it covers this implementation detail. In their defence, they seem to have misinterpreted what you want to do. It looks to me like you just want to integrate / launch your web app from the browser UI?
Web application:
After finding the tutorial (please provide a link next time) I surmise you are referring to in your question, I suspect that what you are actually attempting to convey is different than how I initially interpreted your question. I have edited the question to make this more clear to people reading it in the future.
That tutorial is explaining how to place a link to a web application into the Chrome user interface. Such is, to a large extent, just a bookmark that is able to be placed within other areas of the user interface than the bookmarks bar.
If that is what you are wanting to do, then, yes, you can easily do so in Firefox. Given that the extension is not running external content in the security context of an extension (you are effectively just navigating to and displaying a website), then that should be fine as a Firefox extension. Note that you need to be sure that you are not granting elevated permissions when you launch the web application.
If running a web application is what you are wanting to do, then I suggest you might want to use different semantics to refer to what you are doing. The above is not a "Firefox extension app hosted on server". Saying it that way strongly implies that you are hosting the actual extension code on your own server. The rest of your question implies that the extension dynamically loads external code and runs it. I would suggest that you refer to it as something like: a web application that is launched (navigated to) by a Firefox extension allowing the web application to be started from an icon in the toolbar.
Extension running web sourced code:
However, if what you are wanting to do is have external content running as a Firefox extension, then implementing that functionality is a large security hole for anyone installing the extension. Even assuming that your intentions are totally benign, there is a huge security hole for anyone who is intercepting your traffic, or gains control of your server to inject code into Firefox that runs at the level of an extension (i.e. the malware can have full control of the browser and then of the computer).
Yes, it is currently possible for you to write this for Firefox.
However, given that the extension pulls code from something not packaged within the extension, the extension will never be permitted to be hosted on AMO.
In addition, the plan is that later this year there will be mandatory signing of Firefox extensions through Mozilla. I doubt that an extension like this will be permitted at that time.
You can read a set of Add-on guidelines on MDN.

Not able to debug phonegap app running on windows 8 mobile

I have a phonegap application that has some layout problems. I can run the app in browser for the most part, and this usually get me over the line. But with a new design I need to debug the application layout on windows phone 8.
I'm currently looking at weinre but its not showing anything on the desktop when browsing the local server, I have added the link to my application I have cleaned up everything I can think of. Still blank. Any good tuts around the ones I have read just copy and paste the original docs or are not on my same error.
There's a public weinre server available here:
https://the-weinre.herokuapp.com/
You may have better luck with that than with your local server. There's a demo available on that page, give that a try and see if it works on your windows 8 mobile device.

Launch Windows Explorer from web application in browser

I’m building a PHP web application that runs only using Google Chrome. The organization would like to be able to access certain folders via windows explorer. This is easy in IE using the file:/// protocol but I can’t seem to find a good solution using Chrome.
I’ve looked into registering custom protocol handlers but haven’t really found the answer I’m looking for there. This requirement is grained in stone; they do not want to access the files via web browser.
Does anyone know if there’s a way to launch windows explorer from google chrome either through a special protocol handler or by temporarily launching IE to get the file path to open? A simple method or example would be greatly appreciated!
Thanks in advance.

windows phone 7 does not receive scripts and js files on https

Can't solve a problem that I have regarding windows phone jquery mobile https and asp.net mvc 2. I have a asp.net mvc 2 app that resides on my localhost. Some pages require https connection, so when I use my windows phone to browse through pages everything is fine (jquery mobile renders fine) until I accept the https message and go to the https page then it showes all html content with no javascript and css (white background with black text, jquery mobile not working, hidden divs now visible and so on). Seems like windows phone is blocking the files on https in this particular scenatio. Quite strange problem, especially that everything works on Iphone. Iphone renders everything just fine whether its http or https.
I'm not gonna try to paste any code since I don't event know where to start, and the app is too large to paste code snippets. Just wanted to know if anyone had similar problem, or has any idea how to overcome this issue.
Thanks.
EDIT: by searching through forums I stumbled upon problem of self signed certificate on the server and accesing pages with windows phone, dont know if this is the exact problem tho
I think I found solution to my problem, as I thought I need to add the same self signed certificate to my phone that I generated on the server. It is not necessary on the iphone, but for some reason Windows Phone requiers it.

Scripting disabled in WebBrowser control?

I have a VB6 application using the WebBrowser control. It displays HTML pages from a local folder (using file:// URI scheme). Some of those pages contain embedded JavaScript code.
It all works well for the vast majority of users, but occasionally we get reports from people who have problems with everything JavaScript-related in the pages. Basically, it looks like they have scripting disabled inside the WebBrowser control.
The problem is: I cannot even reproduce the problem. I was trying to fiddle with various settings in IE security (IE8 on Win XP Pro SP3), disabling various scripting-related options for different zones (which zone includes local file system, by the way?), - I'm always having JavaScript running well in my tests.
Does anybody have any idea of what may be going wrong?
Thanks
I think I know why this is happening, it's because the IE version the WebBrowser control renders under is IE 7.0 in most, and if they are using a browser older than IE 7, it will render under IE 4.0 (seriously). They do this for backwards compatibility. So if some of your users have IE 6, their default IE rendering engine will be IE 4.0. Of course, since you are probably using IE 9, yors would be IE 7 engine.
You can change the engine, if this is what you want to do, to the current engine (ie: to the current version of internet explorer installed on the users system).
Also, I'd like you to go to http://whatsmyuseragent.com/ on your IE browser, and then through the hosted WebBrowser control; you'll see the difference.
Also, ask your problemed users to go to http://whatsmyuseragent.com/ through their hosted WebBrowser control if they can, and note the results, if they are running pre-IE-7 then most likely their hosted webbrowser control will show IE 4.0. This is almost certainly the reason for your problem.
