Program should read data from different web-pages and should display on screen at a time.

Hi, I have removed your 'text speak' as it is best not to use 'text speak' in your questions, it is hard enough for non-English speakers to understand technical questions. So always try to use the correct spellings, then everyone can understand you clearly and you will be more likely to get the help you require. Just a suggestion. :)

You need to build a screen scraper engine. A simple one is to use the WebClient (code behind .net) class which can help you make a http request to the page you need. The response contains the html or text. You then just need to parse that html by searching for a text pattern.

You could also do the same using ajax (jquery). Download the html load it in the dom. This can allow you to use jquery to get the element (div/table etc) you are targeting. The trick in this approach is to only display the innerHtml/text of the element you need and discard the rest of the document.

hope this helps.
