BlackBerry progress dialog

I want to show the user a progress dialog until a particular task is complete.

For example, after the user enters userna开发者_运维百科me and password it takes some time to connect as the username and password are validated. I want to show the progress bar to the user while waiting.

GaugeField percentGauge = new GaugeField("Percent: ", 1, 100, 29, GaugeField.PERCENT);

While user is waiting for response u can also show loader screen or an activity indicator.
