Program security (When Launched)

I hope this makes sense... I made a program which requires authorization by username and password, once logged in it will allow you to load a program. My question is, is there a tutorial for the program being called to only open if it has been called by a certain program (Only a certain program can open it).

I was looking up google for tutorials and fstream, but I cannot find anything. Could someone please push me in the right direction?

Thanks in advance,
Rave

Off the top of my head I would say it's not easily possible unless you set up the calling program to run as a unique user. Then you could check to see what user owns your program's process (such as with ps) and terminate if it isn't the right one.
I'm here to prove you wrong.

You could also use a pseudorandom number calculated by the same means on both the client and server programs. You could pass this via an IPC mechanicsm. Not exactly 'secure', but would keep anybody from randomly executing.

I have a idea that will work, once program A is open it will create a .bmp file with encrypted characters. The program B will search for this file and have the correct characters in it. If not it does not open.

However, I want to make it so when Program A is closed, the file is deleted (so program B wont run). How do I delete the bmp file after its been created?

from google

http://www.computing.net/programming...rum/12045.html

C Syntax (Toggle Plain Text) 
  1.  
  2. #include <stdio.h>
  3.  
  4. if(remove("myfile.txt") == -1)
  5.  
  6.     fprintf(stderr,"Remove failed");

apparently the remove() function is what you are after.

www.cplusplus.com might have a reference for this function
http://sales.carina-e.com

no www
no nonsense

coming soon to a pc near you! :cool:
