Pages like this:
http://info.abril.com.br/noticias/carreira/ibm-da-curso-gratuito-de-ingles-a-distancia-06092010-37.shl
are make in which language? Is "shl" a language? I didn't found more about..
File extensions on the web can be misleading. Webservers can be configured to treat extensions any way they want. There's nothing stopping a webmaster from naming all their HTML files ".exe" and calling their PHP scripts ".aspx"
Check that server's output headers. maybe there's a language signature. e.g. PHP can put in an "X-Powered-By" header if the webmaster so chooses.
It doesn't have to be a specific language, it depends on the configuration of the webserver. I would hunt for clues on the page, as the file extension is no help concerning finding out the underlying technology.
Well all webpages - including the example page you link to - are written in HTML and javascript. What the server-side language is that generates (or simply returns) that HTML and javascript could be practically anything.
However, the file ending .shl doesn't necessarily mean the server side language is .shl related. You can have your URLs ending with anything you like.
As far as what .shl file extension might be, I don't know. A google search throws up this: "Inno Setup String Tables file format" but i have no idea what this is.

I realize that this is probably going to be a duplicate question, but I have searched and searched for an answer and am unable to find the right answer. I want to display an image uploaded to my database on a web page. I have tried about a zillion different ways and just can't get it. I would hard code it, but I'm using a "base" page for all the pages so all the information is shown dynamically. I hope this makes sense. I just don't know how to make the image show up? Is this a more than one step process? I'm still fairly new to all this, so it has quite confused me. Thanks for any help!
When a page displays text, this is what happens
A URL ie https://audaxing.wordpress.com/2013/05/20/600km-stage-by-stage/ does a request to a web server
The server sends back a header saying "here comes some html text"
The server finds the appropriate content
the server sends back the text with the content, in html format
For an image
A URL ie http://audaxing.files.wordpress.com/2013/05/img_20130518_194100.jpg?w=500&h=375 does a request to a web server
The server sends back a header saying "here comes an image" including the image format type
The server finds the appropriate content, which will be binary data in a image format such as jpeg
The server sends the binary data back
So all you have to do is send an appropriate header, select the data for the image from the database and then "print" the data like you would a page. You may need to use a special binary mode for the data printing
The exact details depend on the platform (php, scala play, django etc etc) that you are using

I am having issue in applying AJAX so as to refresh certain contents of a table designed in HTML and Perl.
Say, if the contents of the following cells
{R2,C3},{R3,C4},{R4,C(5-7)}, {R(7-10),C(8-11)}
need to be refreshed every 10 seconds,
what shall be the corresponding PERL code for the same?
Millie a Thanks for sharing your Kowledge and Time.
Get the data you want (how you do this depends on how it is stored).
Convert it to JSON (the JSON module is well documented) … assuming you want to use JSON, although it is a common choice.
Output a Content-Type: application/json header (how you do this depends on the method by which you are interacting with your web server, it will be different between Plack / a framework / mod_perl / raw CGI / etc) … the same assumption applies.
Output the JSON text (ditto).
There is a simple example using FastCGI.
You need to build a JS method to Asynchronously obtain content from server side
You need a server side module (pearl in this case) to produce that content, there is no special code requiered on the same . you can use your existing PERL server-side module.

How does one write a language? I really can't imagine how this would be done. Do you have to write some binary code? I think I'm far from capable of writing a real programming language -- I'm a hobby programmer -- but I just want to understand how it works.
I don't ask for 'a working demo' (because I presume that'd be a demo like ten pages long) but the general steps one has to take, what you have to write and what that what you have to write has to do, what language do you recommend (that I think I'm not capable of it doesn't mean I don't want to try).
EDIT:
So is my assumption that one would write some code in an arbitrary language that translates it into an already existent language and compile that to machine code?
PS I accidentally voted to reopen my own question, but I think it's reasonable it's closed, so how can I undo that?
Start by writing a specification and grammar that describe what your language does.
Then, write a parser and compiler that turns your language into a simpler language, such as C or MSIL or Javascript.
Finally, run an existing compiler for that language.
You may want to look into LLVM.

Iam working on HTML.and As for now Im going well.But the thing I want to know is about the submit button.I have created user and password and a submit button and a register button.The basic question on my mind for now is, how and where the user names and password are stored and how they are retrieved back to check if they exist or no ? Where do they save the user names and passwords?
and How do i save the user name and the password that is entered through submit button in some other file? I have written perl scripts and c programs for saving and retreiving passwords using file concepts.But how do i manage them in HTML.Do they also save these data in some file and search for the user and password using some python or perl script and send back the result?
because searching and sorting techniques are powerful with the above scripts.I dont know how to use them in HTML and also the question is,can we use them in HTML?
Please let me know How to make it through.And can we also redirect to some links when we use click button and push buttons ?
Can we use scripting languages like perl in my HTML file if so how?
The <script> element lets you embed any langage you like in an HTML document for client side processing.
The languages supported by browsers are:
JavaScript (universal among browsers that support scripting at all)
VBScript (Internet Explorer only)
PerlScript (Internet Explorer with a plugin that ActiveState used to distribute)
Perhaps some others with support that is about as common as that of PerlScript
So, effectively, client side you can use JavaScript and only JavaScript.
Server side, you can use any language you like. The webserver just needs to be able to communicate (and, while inefficient, CGI just depends on STDIN/OUT and environment variables).

I would like to insert an Excel spreadsheet into a Web page but would like to change some of the data at the same time to make them more user friendly.
Is it easily possible?
Thank you for your help.
Excel can export HTML files directly ("Save as...") What modification exactly do you want to do? Can you do them by hand? Do you want to automate them (how often you want to do the export?)
For small modifications, it's relatively easy to write a VBA macro (or just record it..).
If you don't mind the security risks, you can activate ActiveX and embed the Excel spreadsheet in the web page using the <object> element (see these forum posts for some pointers). Don't browse the Internet with ActiveX enabled! You will get a virus or Trojan.
Note that the spreadsheet must be on a network drive that is accessible by all users.
If that isn't an option, then try Zoho Sheet or Google Docs. Drawback: You must give your previous data to a third party.
Last option: Use a web server to convert the Excel into HTML and use a JavaScript grid control.
