notifications

问题 I write a local service application using C++ and I can't find the correct way of registering for a pre-shut-down notification (for OS later than Windows XP). I believe that SERVICE_CONTROL_PRESHUTDOWN notification has been added since Vista, but when you call SetServiceStatus do we need to specify: dwServiceStatus.dwControlsAccepted = SERVICE_ACCEPT_PRESHUTDOWN; or dwServiceStatus.dwControlsAccepted = SERVICE_ACCEPT_SHUTDOWN | SERVICE_ACCEPT_PRESHUTDOWN; 回答1: You cannot accept both a

问题 Following on from this question I am looking at building a similar notification system and I have a question (which has an obvious answer I think but I'd prefer to have some other opinions): If a particular post generated a million likes, and then someone adds a comment to that post, I would need to notify those million people who liked the post about the comment that was added. Is the only way to achieve this to write a million rows into a NotificationRead table which has the NotificationID

问题 I figured out this issue when I wasnt getting the notification through workmanager when the app was killed from background tasks in Android 10.
