Memory Address

kevinawad · 10-18-2008, 08:16 PM

What if i got this:

Code:

ofstream file("file.txt");

int Address;
int TheAddress;

file << &Address;

Okay now, let's say, in the file file.txt, it's written : 0029F93C

How could i make that TheAddress is Equal to 0029F93C?

I'm trying to retreive it from the file, but it retreives an integer.

Can anyone give me a hand? Thank you

.

And 0029F93C is also an integer, so that's handy. If you mean "how do I read an integer that's written in hex", then you need to set the ios::hex flag.

kevinawad · 10-18-2008, 08:29 PM

Is it possible to set the flag directly while getting the string from the file?

kevinawad · 10-18-2008, 08:31 PM

Here's the deal...

001FF92C = 66952.

001FF92C >> Wads;

Now Wads = 66952.

ReadProcessMemory(client, (int*)Wads, &WadsBuffer, sizeof(int), 0);

It won't read the Wads address...because of it's value.

How could it be possible to make it work?

tabstop · 10-18-2008, 08:33 PM

0x001FF92C equals 2095404, not 66952.

kevinawad · 10-18-2008, 08:34 PM

Hmmm, when i read it from the file...it gives me this value...

Hmmm...

That's a big problem im having...

tabstop · 10-18-2008, 08:40 PM

Reading in hex is not that hard.

Code:

#include <iostream>
#include <iomanip>
#include <fstream>

int main() {
    std::ifstream hexin("hex.txt");
    int wads;
    hexin.flags(std::ios::hex);  //or hexin << std::hex
    hexin >> wads;
    std::cout << wads << std::endl;
    return 0;
}

Remember iomanip for all the flags. (Okay, I lied: flags is in iostream, not iomanip.)

Why do you have a file of memory addresses?

kevinawad · 10-18-2008, 08:50 PM

Code:

file.open(filename.c_str());

file.flags(ios::hex);

file >> Wads;

cout <<Wads;

Value in the text file = : 001FF92C

When printing wads. Im getting 66952

Still having some problems. Hmm...

I'm working on a localhost - kind of server. It will be a debug console. it will access the memory location for the variables in the client.

I'm actually working on a Text Role playing Game.

tabstop · 10-18-2008, 08:55 PM

Check that you're reading the right file, I guess. 66952 is 0x10588, so maybe look for that pattern.

kevinawad · 10-18-2008, 08:56 PM

I am reading the right one :P...Hmmm...Did you try it? does it work for you?

Code:

$ ./temp
2095404

And of course my hex.txt has 001FF92C in it.

kevinawad · 10-18-2008, 09:00 PM

Your right, i just remade a new program. And it worked...I think im reading the wrong file.

Are you aware that you cannot just access a hard coded address? Further aware that even if you can access a hard coded address that there is no guarantee it has the data you want to inspect?

kevinawad · 10-18-2008, 09:09 PM

Wow...I just found out about the problem...But im not sure what causes it?

Code:

	file.open(filename.c_str());
	file >> processid;
	file.flags(ios::hex);
	file >> Attack;
	file >> MagicAttack;
	file >> Defense;
	file >> Speed;
	file >> Health;
	file >> MaxHealth;
	file >> Mana;
	file >> MaxMana;
	file >> AbilityPoint;
	file >> Strength;
	file >> Intelligence;
	file >> Dexterity;
	file >> Ritual;
	file >> SkillPoint;
	file >> MasterSkillPoint;
	file >> UniqueSkillPoint;
	file >> Name;
	file >> Wads;

Alright so, when i want to get the value from the file...it only works if i put one value in the txt file.

My text file:

Code:

41612
0019F9B8
0019F9BC
0019F9C0
0019F9C4
0019F9C8
0019F9CC
0019F9D0
0019F9D4
0019F9D8
0019F9DC
0019F9E0
0019F9E4
0019F9E8
0019F9EC
0019F9F0
0019F9F4
0019F9F8
0019FA14

I don't understand really about the problem.

Doing this works:

Code:

#include <iostream>
#include <fstream>


using namespace std;


int main()
{

	int Address;

	ifstream file("file.add");

	file.flags(ios::hex);

	file >> Address;

	cout <<Address;

	return 0;
}

But doing this doesn't?

Code:

	file.open(filename.c_str());
	file >> processid;
	file.flags(ios::hex);
	file >> Attack;
	file >> MagicAttack;
	file >> Defense;
	file >> Speed;
	file >> Health;
	file >> MaxHealth;
	file >> Mana;
	file >> MaxMana;
	file >> AbilityPoint;
	file >> Strength;
	file >> Intelligence;
	file >> Dexterity;
	file >> Ritual;
	file >> SkillPoint;
	file >> MasterSkillPoint;
	file >> UniqueSkillPoint;
	file >> Name;
	file >> Wads;

Hmmm?
