Shutdown from c++

[ihsir]

Anybody knows how to shut-down a system from c++ program.
I can restart but don't know how to shutdown it.

Some other info if that helps (hey, who knows...):
i use borland 3.0 dos compiler and OS=win98

Typing Rundll32 User,ExitWindows (or something like that... I can't remember it exactly) into the Run command works, so with the right header file (system.h i think) you can use the ShellExecute command:

#include <system.h>
...
...
ShellExecute(this->Handle,"open","rundll32 User,ExitWindows",NULL,"",SW_SHOWNORMAL);
...
...

I think its User,ExitWindows. Try User32 if User doesn't work... I can't remember the exact contect of the command... but that's one way of shutting down a system from C++ (Or from the Run command, and hence from a .LNK shortcut file as well, should the need arise).

i don't think this'll run under borland 3.0

i might be wrong though. thanks anyways i'll chk it out later rightnow im in no mood of programming.

any other suggestions are welcome...

Not sure if this will help you or not but. . .
Here is how you can make rundll shutdown you windoze machine. You can paste this line into a short cut and run it manually or you can execute it through C++. Here is the link { C:\windows\rundll.exe user.exe,exitwindowsexec }

Like The3ntropy said, you don't need C++ to shutdown Win98, just make a shortcut and enter { C:\windows\rundll.exe user.exe,exitwindowsexec } for target. The Shortcut will shutdown your computer.

well i should have maybe told more..

i want to make a c++ program that can shutdown the sys after 3 wrong passwords have been entered.

i can make a program that can restart the computer if 3 wrong paswords have been entered but whats the use of that.

so does anyone know how to...

[Rewandythal]

How have you been getting it to restart, what code do you use for that?

[ihsir]

thanks to Bubba at www.cprogramming.com, maybe i'll ask him again

To reboot the system:

outp(0x64,0xFE);

This will only work if you are in pure DOS (Windows catches this) and if the keyboard buffer is not full. In DOS this will work 99% of the time since the keyboard buffer being full is a rare occurrence

Did you want to shutdown from DOS, or Windows?

The code I posted above will only work in Windows, as far as I know. As for shutting down from DOS, I don't know any code off the top of my head.

>>Did you want to shutdown from DOS, or Windows?

yeah it was from dos,
