A program written in C to make the computer shut down automatically

Use cmd's timer to shut down.

private void button1_click(object sender, eventargs e)

if ( msg==, "shutdown -f -s -t 1");Force a one-second countdown shutdown!

else return;

"", "shutdown -s -t %time%");

time is measured in seconds, and if you say a minute, you're hitting 60

If you want to use a parameter, it's useless to have no parameter.

s Shut down. l Logout.

r Reboot. Then there is -t + time.

You need to write shutdown + what you're going to do + t when you're going to do it.

Run the following: shutdown -s -t 0 can't be closed?

Isn't it to prevent children from being disobedient? Poor father, huh. It's really hard to do.

If you're smart and know how to change the time in the bios, there's no way around it. Unless you use a network clock, it is when you turn on the computer, as long as your computer can access the Internet, you can get the time, and then compare and then perform the shutdown event. Of course, if he doesn't go online.

You don't have to be so harsh either. He may be studious. Also, this program is better made as a service-oriented program.

This way, at a higher level, he won't necessarily know how to end your program. Otherwise, the program will be stopped in the middle of the process. You're working in vain.

It's also a good thing that you can do this kind of program for him to break. If he wants to play with the computer, he has to learn how to break your program. After a long time, he may like to compete with you, and this result may be what you want, right??

Nothing else. I don't know much about service-oriented programs, and others might be able to help. Let's think about it before we do it.

Let the program run on the machine, get the current time of the system after running, and then just sum"10：00"Compare, if the shutdown is performed later than this time**.

Speaking of which, I have to say that if the user somehow changes the system time to before 10:00 before your program obtains the time, it will not be able to achieve automatic shutdown after the time is up. Personally, I think that if you want to ensure this point (that is, the user modifies the time before 10 o'clock, the program can still work normally), either add the current date, time and other detailed information in the shutdown**, and then get the time again and the saved date and time to calculate the difference.

For example, when the computer is turned off, it is 10:00:00, and when the computer is turned on again, the time becomes ...

This is obviously a modification of the time.,Continue to perform the shutdown**。 As for saying that if the time is changed and a new day begins, you can see what happens.

Call the system command, automatically shut down, delay one second Timing 1:02 shutdown, time change at will.

It should be a mobile phone protection function, the mobile phone will automatically shut down when it reaches a certain temperature, and now the temperature is too low in winter. Apple also sometimes suffers from this problem.
