![]() The maximum length of the comment is 512 characters. You must include quotes around the comment. This command option allows you to leave a comment describing the reason for the shutdown or restart. If neither p nor u are defined, the shutdown or restart will be recorded as unplanned. The xx and yy options specify major and minor reasons for the shutdown or restart, respectively, a list of which you can view by executing the shutdown command without options. The p option indicates a planned restart or shutdown and the u a user defined one. This records a reason for the restart or shutdown. The /t option is not available with either the /l, /h, or /p options. If you don't use the /t option then 30 seconds is assumed. The time can be anywhere from 0 (immediately) to 315360000 (10 years). This is the time, in seconds, between the execution of the shutdown command and the actual shutdown or restart. This command option specifies the remote computer that you want to execute a shutdown or restart on. ![]() Except with the /l, /p, and /h options, not using shutdown's /f option will present a warning about the pending shutdown or restart. This option forces running programs to close without warning. The /hybrid switch is new beginning in Windows 8. This option performs a shutdown and prepares the computer for fast startup. The /o switch is new beginning in Windows 8. ![]() ![]() Use this switch to end the current Windows session and open the Advanced Boot Options menu. This option enables documentation for an unexpected shut down in the Shutdown Event Tracker. You can not use the /h option with the /m option to put a remote computer into hibernation, nor can you use this option with /t, /d, or /c. You can not use this option with /t.Įxecuting the shutdown command with this option immediately puts the computer you're on into hibernation. Using the /p option is similar to executing shutdown /s /f /t 0. This command option turns off the local computer completely. Remember to use the /m option if you're planning on stopping a pending shutdown or restart that you executed for a remote computer. Use this option to stop a pending shutdown or restart. This shutdown option functions the same as the /r option but will also restart any registered applications after the reboot. This option will shut down and then restart the local computer or the remote computer specified in /m. Use this option with the shutdown command to shut down the local or /m defined remote computer. The /d, /t, and /c options are also not available with /l. You can not use the /l option with the /m option to log off a remote computer. This option will immediately log off the current user on the current machine. The /i switch must be the first switch shown and all other options will be ignored. ![]() No manual updating of fields - saves code and threading headaches and you could go for a "real" (=threaded) timer approach.This shutdown option shows the Remote Shutdown Dialog, a graphical version of the remote shutdown and restart features available in the command. If you use WPF you should really use binding and not code-behind. Bonus: This way you can make your timer intervall shorter than one second and get a more "smooth" time display.ģ. Why?: Gui-Timer-Events will be thrown away if not processed between ticks, so in your app it can happen that the timer doesn't "see" a tick for some intervalls and your "time calculation" goes wrong. Better: Store the "start time" and get the current time inside timer tick, than calculate difference between start time and current system time and apply your math. If you calculate the "elapsed time" in your timer tick - so you can update the GUI - never use the tick-Intervall for calculations (your timeleft variable (should be named secondsleft.). Even worse in a WPF app a Systems Windows forms timer.Ģ. So I feel you could need some tips (maybe for your next app?)ġ. But you use a fundamentally wrong approach. For your purpose and desired accuracy it seems ok. The only thing I quickly recognized was the "missuse" of a timer. ![]()
