Hello:

My application needs to register and report the power off the system. But it turns off before this happens.

Can someone show an example?

Thanks

To intercept the "Power off" event - use method: powerOff() in net.rim.device.api.system.SystemListener inteface.

Note that you cannot delay power off process.

Is there a way to have a dialog alert when you are trying to power off?

[tbilisoft]

Yes, you can try to display it in powerOff() method.

But it does not make sense.

The system uses powerOff() to notify you that it is turning off.

It won't wait until your dialog is dismissed nor until you do something.

There is no mechanisms to control power-off behaviour.

Thanks for you answer. I have a client that wanted to be warned and give them the option to power off. I wasn't sure if that was possible. So there is no way to cancel the power off (Red Key) on phone?

[tbilisoft]

No, unfortunately there is no way to cancel powerOff event.

[scottsheppard]

Is there a way to change the message when the phone is powering off. Like instead of press any key or what ever it says to some thing else?

[tbilisoft]

Unfortunately there is no way to force the operating system wait something before powerOff() nor override standard popup nor make your own popup instead of that.
