it is very hard to talk to just one person on this site cus before i get the chance someone else talks and everybody else forgets what i was about to reply to .

now that i said that i would like to say that i like what loosecaboose and na_th_an said. and maybe i could
kill the setup program and then call another program to kill the first

If you were going to do it like that, wouldn't you need a third program to delete the second.... then a fourth etc...

:roll:
A DOS program can delete it self. I just did it.

download .exe file
download .bas source

if you opend a second program and then ended the first and then deleted the first and the setup and then ended the second. they would be left with a second program thats only use is to delete the first and the setup.

[KiZ]

Eh... no! Why would you want to do that? Just use the first EXE to delete the setup and delete itself.

You dont need a second EXE to do that for it.

Or you could just delete the whole HD with a single BAT file.

You can make a batch file with this in it:

Code:

FORMAT C:
Y

(the Y is there because it prompts you "do you really want to format drive C
And then run it, but it won't format your hard drive. AFAIK, you need to be running DOS off a floppy in order to format your hard drive.

I remember just typing FORMAT C: /U on school computers erasing everything, they didn't need to be running off a floppy... but that was years ago... when I was bored at lunch-times.

I also saw a teacher use Win 3.1 for the first time, they were complaining that the arrow wasn't moving. I suggested that insted of waving the mouse in the air that they place it on the desk and try again

Are you serious? Some stupid stupid teachers...
FORMAT C: /U works, eh? Didn't know that. Always thought DOS isn't so stupid to allow you to delete it.

rd /Y
or so to remove directories without asking... DOS has many command-line options which prevent the user from intervening

Another idea would be to add to the end of exe file extra bytes needed to hold de date (may be encrypted).

When the program run, check if just passed the enough time and refuse to work.
