ProgressDialog used with IntentService

Hi. I have a button on one activity, the user presses it and it opens up a second activity. The second activity queries a server and sends data back to the activity via an IntentService. I am trying to put a ProgressDialog when the second activity starts and dismisses after a certain amount of time. Can someone please help me with this as I am quite new to Android. I appreciate any help, thanks in advance.

Google "Android ProgressDialog"
