You need to call SysNotifyRegister with the cardNo and dbID of the your app not the apps which you want to track. So you'll receive a notification when any and all apps exit. In your notification handler, you'll need to compare the dbID in the notification with thoses of the apps you are tracking.

To do so, I follow these steps: 1. I get the card number and database ID of the applications I want to track using DmGetNextDatabaseByTypeCreator(true, stateInfoP, 'appl', 'xxxx', true, &cardNo, &dbID) (where 'xxxx' is the 4 letter creator ID of the application I want to track, not the application I try to develop). I make sure that the function returns errNone and it always does. 2. I then register to receive notifications from the applications for which I just got the card number and database ID using SysNotifyRegister(cardNo, dbID, sysNotifyAppQuittingEvent, NULL, sysNotifyNormalPriority, NULL). I make sure that the function returns errNone and it does. 3. I added code in the PilotMain to handle the sysAppLaunchCmdNotify launchcode so that my application's preference is updated during a sysNotifyAppQuittingEvent event. Unfortunately, my application's preference is never updated which tells me that my application never receives the notifications. Besides, when I close and restart my application, I should get the sysNotifyErrDuplicateEntry error when I register the other applications again (to indicate that my application is already registered to receive notifications from the other applications) but I don't (I get the errNone instead). Can anyone tell me what I am doing wrong?
