When I create http request connection and download the information, I can see the blackberry default loading icon appear. But it does not appear everytime when I create the connection.

How can I make it appear everytime and disappear everytime in the program code control?

If you are talking about the spinning hourglass, or clock, this is a bad thing. It means that your application is holding up the OS by blocking on the event thread. If you do this too much the OS will kill your application. You have to do your http request on a new thread. If you want to display a progress or busy indication you will have to do that coding yourself, again, use a thread specifically for the indication so you don't block the event thread.
