well ok...
this is the code that i have made
code:

#include <iostream>
#include <fstream>

using namespace std;

void main()
{
const int& addr=0x00A88084;
cout <<addr<<"\n";
} // end of main()

But, when i compile i get the address instead of the value that the address holds can u help me with that?!

is this what you are looking for?
code:

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
int number=5;
int* addr=&number;

cout <<*addr<<"\n";
system ("PAUSE");
return 0;
} // end of main()

i know how the pointers work but this not exactly a pointer...
see 0x00A88084 is the address that the value is stored at in the memory... that's where i wanna access...

I think homer wants to go through his RAM stick searching for where mazer is hiding his values and change them Laughing

you could always cast it to whatever type the value is
code:

int* addr=(int*)0x00A88084;
*addr=5;

are you sure homer?

cuz the way I figure it... takes 2 minutes tops to unscrew computer's case, grab the ram stick and put it all back together... and it might take weeks before anyone would notice Laughing

heh... well i'm positive because i checked it with a memory check program... no need to open my case Laughing

Post subject: 
yeah... well you would probably find out... so would I and many more users around here...

its just that me and my friend estimated that if two of us were left in computer lab for 15 minutes with 2 screwdrivers, we would get a shitload of ram for ourselves Laughing

heh... u must have a pretty big mother board if u wanna intsall 100s of 8 mb ram memory(our school lab's rams are 8 mb i think Very Happy)



man i have done this program b4(in Turbo Pascal)... i did it when i was 10 or 12 it worked awsome... i used to make it read all my memory(i had 8mbs) and it would give me back the usefull stuff like system codes or all the thing that had been typed programs (including passwords)in fact every thing that was declared as a variable sometime... BUT I DONT REMEMBER HOW I DID IT!!! Crying or Very sad

neah, I was talking about my nice P4 lab... though they still run slow. That piece of shit. If you order the newest computer you can find, by the time it will be delivered, it would become obsolite. Thats even with a "next businessday delivery" Laughing

you can't acces raw memory locations.
Windows 2000 onwards will prevent ur application from running!!
