Hi everyone. I am working on a project which has to change the value of a variable in the executable. Specifically, writing this program:
int a = -1;
int b = 3;
int c = a + b;
I have to go into the executable and change the value of "a" into the executable. Let me not extend this too much, and show you what i have done. At this moment I do not know why this is not working. I am trying to make sure that I am looking at the right place before I try to change the value. Thanks for any help you can give me.
#include<iostream.h>
#include<fstream>
#include<stdio.h>
#include<string>
using namespace std;
int main()
{
ifstream myFile;
ofstream fout;
char temp1;
myFile.open("C:/Documents and Settings/Angel/Desktop/Virus/Hex/Debug/Hex.exe");
if ( !myFile ) //(myFile.is_open())
{
cout << "File could not be opened.\n";
myFile.close();
}
else
{
myFile.seekg(0x0000158B); //Seeks the positon of variable a in the binary file / executable.
myFile.read(temp1,1);
cout << "Value is " << temp1 << endl;
myFile.close();
}
return 0;
}
