1. Windows Shutdown
Hello to all,
I have been using the following code at the end of this message to try
and shutdown windows, but unfortunately it only logs the user off, and
not completely shutdown the PC. I did some research on the MSN website,
and I found out to shut down or restart the system, the calling process
must use the AdjustTokenPrivileges function to enable the
SE_SHUTDOWN_NAME privilege. The problem is I do not have a clue on how
to do that. Can anyone help out with this?
constant USER32 = open_dll("user32")
constant SHUTDOWNEX = define_c_func(USER32, "ExitWindowsEx", {C_UINT,
C_LONG}, C_INT)
global constant
EWX_FORCE = 4,
EWX_LOGOFF = 0,
EWX_POWEROFF = 8,
EWX_REBOOT = 2,
EWX_SHUTDOWN = 1
global procedure win32_shutdown(integer shutdown_type)
integer x
x = c_func(SHUTDOWNEX, {shutdown_type, 0})
end procedure
Thanks in advance,
Chris
2. Re: Windows Shutdown
The Windows shutdown process is very buggy. It works differently from one
computer to the next.
A small assembly language program that will shutdown, logoff, play sounds, open
and close a CDROM, an entertaining and educational screensaver, and much more is
called WIZMO and can be found at GRC.COM. (This guy does EVERYTHING in assembly
language, even his own Web server and TCP/IP drivers.)
Louis.

Yes ... Or at least differently from one Windows flavor to the next.

I agree that WIZMO is a nice program, but even WIZMO does not reliably
shut down all PCs.

4. Re: Windows Shutdown
One of my points was that if Steve Gibson (WIZMO) couldn't get Windows to
behave, nobody else could either.
By the way, an earlier post mentioned using the FORCE parameter when calling for
a shutdown. Although sometimes necessary to overcome the Win98 shutdown problem,
I believe this can shut down programs before they are ready, before they have
written their buffers to the HD, resulting in data loss. It helps to wait a
while after closing all applications before forcing a shutdown.

Oops, it seems that I misunderstood you. Sorry.
Now I see that we have the same opinion.
