reboot

问题 I'm setting multiple alarms so they can be repeated on specific days. Now I have heard that Android doesn't save the alarms on reboot. I have also read that BroadcastReceiver should be used when BOOT_COMPLETED to reschedule all the alarms. But how do I tell the BroadcastReceiver to reschedule alarms after reboot if I have 5 alarms per day = around 35 alarms scheduled on different days. Do I need to store them in the database or? How do I store them? Or is the BOOT_COMPLETED all I need? Is

问题 This question already has answers here : how to detect Linux shutdown/reboot (2 answers) Closed 6 months ago . I have an application written in C which runs as a daemon and needs to send something through RS232 when system is in shutdown or reboot state, and it needs to distinguish between these two.

问题 I have a Qt 4 GUI where I need to have a option in a drop-down menu that allows the user to choose to restart the computer. I realize this might seem redunant with the ability to restart the computer in other ways, but the choice needs to stay there. I've tried using system() to call the following: a suid-root shell script a non-suid shell script a suid-root binary program and all of them just cause reboot: must be superuser to be printed. Using system() to call reboot directly does the same

问题 I am working on an installer using Wix 3.5 that needs to set the system PATH environment variable. This is how I am setting the environment variable: <Directory Id="DirectoryName"> <Component Id="ComponentID" Guid="{BE20AF67-5943-4AF4-BE66-226E2D4B844F}"> <Environment Id="EnvironmentID" Name="PATH" Action="set" Value="the path" Part="last" Separator=";" System="yes" /> </Component> </Directory> This seems to be working on 32-bit systems without requiring a reboot for the changes to be

问题 I have a set of alarms that I need to keep after reboot. I've tried using on an boot receiver but they won't start again. I'm not sure if I understand the boot receiver and how to then restart all the alarms. I already have one receiver for my notifications, but don't know whether I can use the same receiver or if I need a new one? Could anyone point me to any good tutorials or help me out? Cheers Code : DatabaseHandler db = new DatabaseHandler(this); List<UAlarm> alarms = db.getAllAlarms();

问题 I am testing installation scripts and must put Windows into a state that a reboot is pending from another installation. I have read how to test whether a reboot is needed.
