用ExitWindows来写个程序并且能设置时间的，能让电脑到设置的时间就能自动关机的

新手上路最好详细点，用ExitWindows来写个程序并且能设置时间的，能让电脑到设置的时间就能自动关机的

解决方案

用不着，直接调用Shutdown命令行（可以用ShellExecute或者Winexec）

C:Windowssystem32>Shutdown
Usage: Shutdown [/i | /l | /s | /r | /g | /a | /p | /h | /e | /o] [/hybrid] [/f]

[/m \computer][/t xxx][/d [p|u:]xx:yy [/c "comment"]]

No args    Display help. This is the same as typing /?.
/?         Display help. This is the same as not typing any options.
/i         Display the graphical user interface (GUI).
           This must be the first option.
/l         Log off. This cannot be used with /m or /d options.
/s         Shutdown the computer.
/r         Full shutdown and restart the computer.
/g         Full shutdown and restart the computer. After the system is
           rebooted, restart any registered applications.
/a         Abort a system shutdown.
           This can only be used during the time-out period.
/p         Turn off the local computer with no time-out or warning.
           Can be used with /d and /f options.
/h         Hibernate the local computer.
           Can be used with the /f option.
/hybrid    Performs a shutdown of the computer and prepares it for fast star

tup.
Must be used with /s option.
/e Document the reason for an unexpected shutdown of a computer.
/o Go to the advanced boot options menu and restart the computer.
Must be used with /r option.
/m computer Specify the target computer.
/t xxx Set the time-out period before shutdown to xxx seconds.
The valid range is 0-315360000 (10 years), with a default of 30.
If the timeout period is greater than 0, the /f parameter is
implied.
/c "comment" Comment on the reason for the restart or shutdown.
Maximum of 512 characters allowed.
/f Force running applications to close without forewarning users.
The /f parameter is implied when a value greater than 0 is
specified for the /t parameter.
/d [p|u:]xx:yy Provide the reason for the restart or shutdown.
p indicates that the restart or shutdown is planned.
u indicates that the reason is user defined.
If neither p nor u is specified the restart or shutdown is
unplanned.
xx is the major reason number (positive integer less than 256).
yy is the minor reason number (positive integer less than 65536).

/t参数就可以设置倒计时时间。

解决方案二：

设置一个界面，来设置时间。得到时间后。用SetTimer来做一个定时器。到时间后。调用ExitWindows来关闭计算机
