Set a javascript timer to poll a database every few seconds using xmlhttprequest. Use the Document Object Model to insert new text into the browser. You can determine what text is new using a timestamp, hash key, row count, or some combination.

what does 'difficult to select' mean ? It sounds like your firefox is not drawing the radio buttons well. You have to explain yourself better. If the buttons are too small, try using CSS to make them bigger perhaps ?

im doing a project in ASP.NET using C#. I have used a multiline text box in which when i type any url or mail id,it should be
displayed as hyperlink at once,and other typed data remains same.

A syntax highlighting textbox on the client side ? I doubt you can do that with javascript. Perhaps with an embeded .NET or java control ?
