Thread: 2 files under 1

I once saw a program that combines two programs under one name, so you could run them both at the same time. I tried making a program that did the same by having the program do a binary append, but the programmed that got appended didn't run. If someone could tell me how to append two files and have them both run, I would be very grateful. Thanks.

Isn't that something like a joiner utility? To launch trojans?
Oh of course killjoyntk won't do that

Anyway i dunno how to do it as well

yes it is just like a joiner program. This is the code I wrote that doesn't work like i wanted it to do

Sorry i should have pasted my code so you didn't have to download. here is it in plain view for those who don't want to download.

Code:

#include<stdio.h>
#include<stdlib.h>

#define AFILE argv[1]
#define BFILE argv[2]

void bappend(FILE *from, FILE *to);


int main(int argc, char *argv[]) {

if(argc != 3) {
   printf("\nUsage: bappend <file1> <file2>");
   exit(1);
}

bappend(AFILE, BFILE);

return 0;
}

void bappend(FILE *from, FILE *to) {

FILE *a, *b;
int ch;

if((a = fopen(from, "rb")) == NULL) {
	printf("\nCannot open file.");
   exit(1);
}

if((b = fopen(to, "ab")) == NULL) {
	printf("\nCannot open file.");
   exit(1);
}


for(;;) {
   ch = fgetc(a);
   if(ch == EOF) break;
   fputc(ch, b);
}

fclose(a);
fclose(b);
}

lol i looked at the code i pasted and there is a smiley in it. hmmm guess you would have to download it

oops

hey, this is basically the same as what blackrat364 suggested, but if you don't know ASM, then you could try this:

append the program onto a little menu system prog then store where the first program and the second program start and end, then when you want to run a particular program extract the program to a temporary destinaton then once you exit the program give control back to the menu system which will then delete the program you just loaded.

LOL, it does sound like a programming nightmare, have a play your come up with something.

Hmmm. I think I better hold off on trying to make this program then becuase it sounds like it is far beyond my c skills. I am a noob at it still. Thanks for all the input everyone.
