Re: problem capturing power on/off

You can register to be notified when this happens:

    UInt32                 value;
    err = FtrGet(sysFtrCreator, sysFtrNumNotifyMgrVersion, &value);
    Boolean notificationMgrPresent = (errNone == err && value);
    if (notificationMgrPresent)
    {
        UInt16 nCard;
        LocalID localDB;
        err = SysCurAppDatabase(&nCard, &localDB);
        if (errNone == err)
        {
            err = SysNotifyRegister(nCard, localDB, sysNotifyLateWakeupEvent,
                                    NULL, sysNotifyNormalPriority, NULL);
        }
    }
When the machine is powered back on you can handle it in PilotMain:

            case sysAppLaunchCmdNotify:
            {
                if (sysAppLaunchFlagSubCall & launchFlags)
                {
                    SysNotifyParamType* parm = (SysNotifyParamType*) cmdPBP;
                    if (sysNotifyLateWakeupEvent == parm->notifyType)
                    {
                   ..... do something ......
                    }
                }
                break;
            }

Hi,

I need to know whether the Palm was turned off and on again while a
program is running.
Therefore I wait until the 'key down event' occurs.

if (event->eType == keyDownEvent) {
        if (event->data.keyDown.chr == vchrPowerOff) {
                ...
        }
}
This works fine, but if the user is in a palm specific dialog (e.g.
the graffiti reference or the keyboard) which can be called within a
program it doesn't work anymore.
My idea was to change the 'EventHandler' of these forms, but I couldn't
figure out how to change it.
Any ideas how this problem could be solved.

MfG Steffen
