and thanks for looking.
Imagine your standard barebones Windows Phone app. Say, I have a URL in mind. I want to be able to view the HTML source for that URL, because I'm looking for particular info that is on that page. Is there any way to do this?
Peace.
You can pull down the html for any page using HttpWebRequest. This project demonstrates that among other things.

If scraping data from webpages, be sure to verify the rights granted by the site's owner for that purpose.

print.print_always_silent use to print the page without print dialog box. My question is, can we do this my PHP / JQUERY code?. Please Help me how know well abt this.
I hope not. That would mean any website could print any document from my printer when they want. Would be a huge security hole imho
This is certainly not possible through the browser with PHP, which runs on the server. It's also not possible with javascript: browser security ensures that. Imagine what might happen if any web site could print whenever it wanted to.
There are (or were) ActiveX controls available for IE that enabled this. It might be possible with a browser extension for Chrome or Firefox if you want to explore that.
One other possibility is setting up a printer on Google Cloud Print and having your PHP server print directly to that, bypassing the browser altogether. Handling the authentication behind such a scheme could be tricky, but the API is documented on Google's site.
There was some coding error recently, and the site was down for a couple of hours during working hour.
Our site is basically a publishing site, user can upload some excels and we grab information and generate some pdfs.
The final pdf location is something like
https://SomeUrl.url.com/Documents/ClientName/DocumentName.pdf
Documents is the controller and we map it to some action and ClientName and document name are the parameters.
What the client want is that even if the site is down (means they can't upload or modify anything), they want the above url to be still up.
Other than rewriting the whole logic, is there something we can do in IIS level?
I thought about url rewriting or url redirect, but don't really think it is possible.
Anyone got any ideas?
Many Thanks
URL Rewrite IIS Extension won't be helpful as it's based on URL pattern. It doesn't care about whether the site is up or down.
You should consider setting up a load balancer instead. It's its job to decide which server to hit depending on server current load or if it's available or not.
So I'm writing a post on my wall and type a URL into the main body of the post. As soon as I finish the URL, Facebook creates a little section underneath which has the title, description, and an image from the url I typed.
Without getting too indepth, how is this done and what is the best way of make something similar myself?
jQuery (or some other framework that lets you do Ajax easily) to communicate between browser client and webserver
PHP/ASP.NET/Python (or some other scripting framework on the backend) to fetch the url
Facebook also has a meta data specification you might be interested in, to let developers further define what gets shown in a Facebook page.
I believe Facebook is written in PHP. And PHP does this easily.
FOpen can be used to access files on other sites. There are other functions but this will get you started. Then it's a matter of parsing the html you get from the url to get what you want.

You have a couple choices. You can fetch it using Ajax from the client; or you can fetch it from your server.
If doing it from your server in asp.net then you need to use HttpWebRequest.
FB does an asynchronous JavaScript call to fetch that data without reloading the window you're on. Lookup ajax and libraries like jquery do this: http://api.jquery.com/category/ajax/
I'm seeking for solution how to isolate widget included by partial to main site. Issue appear when user access site with https. Ie 6,7 shows security confirmation dialog (part of website resources are not in secure zone).
First of all I download twitter widget on our side, also I download all CSS and pictures. Then I patched widget JS to point onto downloaded resources. But still has not luck with security warning :( I guess the reason of this issue is AJAX request to twitter, but there is no idea how to sole it. (Just to create some kind of proxy on our side).
Thank you for attention.
You just need to host the .js file on your server, and link to that. That is all.
The script auto detects SSL and will make requests to https://twitter-widgets.s3.amazonaws.com/ instead of http//widgets.twimg.com/ dynamically depending on your scenario.
Hope that helps!

I got the Twitter Widget to work over HTTPS (SSL) by doing the following:
Save every image, css, and javescript file on my local webserver
Changed every "http" to "https" in the javascript AND in the css
The last piece was tricky. https://twitter.com/statuses/user_timeline.json brings back data that already includes "http"; namely avatars and the profile image. So, I found about four places in widjet.js that used the user_timeline.json data. I hardcoded an image url where ever that "http" data was used. Searching "src" will located all of those places.
It's an ugly fix, but it worked.
You can use a sniffer like HttpWatch to debug this--watch the requests going by and see which ones start with http instead of https. It may be possible to just change the urls you use to point to https://twitter.com, not sure about how your widget works.
thanks Keshar, worked for me. I came to the same conclusion that all http requests had to be https to prevent the IE security warning and also display the twitter feed. I used the live HTTP headers firefox plugin which helps for showing any non-secure http requests, such as the JSON requests.

If you look through the script there are calls to a https site. If you simply replace the protocol/domain with
https://twitter-widgets.s3.amazonaws.com/
instead of
http//widgets.twimg.com/
it works and you don't have to do anything else.
I'm curious to know which web framework or content management system a website is using based upon clues from the URL, headers, content. Does anyone know of a resource on the web that would provide this? For example:
.html -> maybe a flat-file
.php -> something built using PHP, perhaps.
.jsp -> something using Java Server Pages
.asp -> Active Server Pages
0,2097,1-1-1928,00 -> Vignette CMS
.do -> ??
Thanks.
Finding CMS by url

enter URL in center input field and click big blue button below
Results in black - not found,
in red - found
NOTE:
May play around with url path: with http://, with or without www. part -- results may differ.
If you're not restricted to just the query string then there are a few other options. For example to identify a rails app:
Script, stylesheet and image tags tend to have a 10 digits number appended (this allows you to cache, and still change the file):
<script src="/javascripts/all.js?1236037318" type="text/javascript"></script>
You can also sometimes tell from the cookies what the framework is. For example rails apps tend to have a session cookie called _appName_session, and often you can find a flash contained.
You're on the right track with your list there. If all you want to know is the stack (LAMP, IIS, Java) then that's all you really need.
If querying the URL in question is an option, then you can usually pull the webserver make/version out of the HTTP response header as well.
