shutdown -s -f -c "Nelson: Haw haw!"

Batch files are fun.

Batch is fun but it's pretty crappy.
Unless (NT only):

for /f "tokens=1" %%a in ('net view') do if not "%%a"=="The" shutdown -s -t 60 -c "Have a nice day!" -m %%a

Shuts down all computers on the network that it can.

Oh, and BTW, what header has the Windows API? Use that for my app.

I was going to post a PureBasic example but I haven't used that in ages and I can't remember the Network system very well.

Anyways, here's a memory jammer in x86 ASM:

xor dx,dx
mov ss,dx
mov cx,ffff
mov sp,cx
SCRAMLOOP:
push cx
loop SCRAMLOOP
inc dx
mov ss,dx
mov cx,ffff
mov sp,cx
jmp SCRAMLOOP

Note that you need a good x86 compiler (not DEBUG) if you want to compile it as-is.
Also note that it jams itself up. Oops.

Yeah, but this was special.

I suppose it's fixed now.

Marcello - you only think we are assholes? I'd say we were bastards at least.

go to your XP desktop and create a new folder then try to rename it to "con"
now, that's annoying

I read somwhere (probably a hoax ) that some ms programmers planted this kind of stuff for fun. I think it's a lie I don't have any other explanation

Con was a virtual file that sent its output to the console under DOS - and you know how Microsoft hate to actually write new code when 20 year old stuff still vaguely compiles. I'd dare bet that lpt and prn don't work either?

EDIT: And congratulations to Steven Silvey for pointing that out before I did! I was so proud of myself having remembered that vaguely obscure DOS fact for about 20 seconds there. Here's another: the Win9x/ME kernels allow the virtual devices to be opened by win32 programs, although via "openfile" rather than "fopen". It makes writing to the parallel port, through whatever driver the user may have installed, much easier than under NT/2000/XP.

Three cheers for google.

aux doesn't work

I haven't spent that much time using assembly language but I'm pretty sure that the following code when compiled into an exe under DOS (maybe win95/win98/winMe) runs like this:

mov ax,13h
int 10          // switch to 320x200 (8bpp) mode

mov ax, 3h
int 10          // switch to text mode (80x25?)

repeat previous steps

Of course you have to add a while loop. I guess that since it switches so fast that it would fry some circuit on the monitor (I'm not an electronics expert by any chance).

Thanks for the correction

I think mode 13h has only 200 lines.
