Thread: how do you in c++ access memory that not in the current process

say i wanted to change some memory that i know is a int but in another program ,,

Code:

how can get my current code to say if(memoryaddress == value)
{dosomething;}

i was thinking of doing something like 

#define 00xfcblah.... for the memory addresss
 or char ad[] = "00xfcblah";

anyone know?

You can't. All modern operating systems have protection against that. Besides, there is no way of possibly knowing the memory address of a particular integer if you don't have an identfier to it.

It's a secret!

Why would you want to do this?

If you're calling functions in another one of your programs, you can instead link those functions to your program.

Who knows? It seems to me that since [s]he knows it's an int, it might be one of their programs.

You could use a file or something to transfer information between programs.

yes well thats what it is

its
#include <iostream>
#include <windows.h>
using namespace std;

Code:

int main()
{
int t = 0;
while(1){cout<<"the value of t is " << t <<endl; cout<<"the address of t is " << &t<<endl;}
sleep(5000);
return 0;
}

now i would run this and then run the other thing if i had it ,,,
amd change t from another program
i am just interested thats all

But you're not answering the question of why you feel you need this. Is it just a matter of curiousity?
