I don't know what language it's in, and whether we need the authors permission : But can someone convert this to a DLL ?

I've seen this code before but I don't think this is very useful... It looks
like it's written in C++. The problem with the code is that is doesn't
power off a computer but it only gets it to the point where "It is
now safe to power off" message. The same thing as this code can be
achieved with the DOS SHUTDOWN command.
| Quote: | Usage: shutdown [-i | -l | -s | -r | -a] [-f] [-m \\computername] [-t xx] [-c "comment"] [-d up:xx:yy]
No args Display this message (same as -?)
-i Display GUI interface, must be the first option
-l Log off (cannot be used with -m option)
-s Shutdown the computer
-r Shutdown and restart the computer
-a Abort a system shutdown
-m \\computername Remote computer to shutdown/restart/abort
-t xx Set timeout for shutdown to xx seconds
-c "comment" Shutdown comment (maximum of 127 characters)
-f Forces running applications to close without warning
-d [u][p]:xx:yy The reason code for the shutdown
u is the user code
p is a planned shutdown code
xx is the major reason code (positive integer less than 256)
yy is the minor reason code (positive integer less than 65536) |

Actually it's a console mode program written in C/C++ and it will only run on
Windows NT/2000/XP. From the code I'm reading this will shutdown a
computer remotely and display a message to the user if specified in the
command line.

Yes, but will it power off the remote computer? With the DOS
shutdown command it will display a message etc. like you said.
Also, it is written in C or C++? I've got LCC-WIN32 sitting around here
and if it's C I might want to compile it.

And there's also this on www.matcode.com -- undocwin.h:
| Code: | /**********************************************************************/

// Function SwitchToThisWindow

//
// Arguments: hAppWnd - Identifies the main thread window that

Will that help power the remote computer off?

From my intrepretation of the code, and I program in C/C++ also, it will
shutdown a remote computer.
And yes it is written in C/C++. You can compile it either way.

FF the file you just posted just has a couple of simple functions. Nothing to
do with remotely shutting down a computer in there.

As you can see I'm a complete beginner in C/C++/Delphi/etc. and I
have a LOT to learn about it. Someday I'd like to be able to make my
own DLLs though!

Don't let yourself get frustrated with it, and don't try to learn too much at
once or you'll drive yourself crazy, trust me.
BTW, any questions ya need answered in the C/C++ department I'll be
more than glad to try and answer for ya.

Hi Rubes_sw,
I will make you a VDS DLL with just this function that you posted. It is no big deal
