Code:
01 00 00 00 00 73 74 65 72 2F


This AOB is 10 bytes long, so your going to be doing this:

Code:

SIZE_T bytesRead;
BYTE    bytesFound [9] = {0};

ReadProcessMemory ( hProcess, lpPtr, &bytesFound, 10, &bytesRead );
 


Then, your going to compare the values.

Code:

// I think its in reverse order
for ( int i = 0; i < 10; i ++ )
{
   if ( bytesFound [i] == '\x01' )
   {
      etc...
   }
}


hope I helped somewhat.

not sure if there is a specific reason why you do '\x01' (perhaps it's a specific coding style, like urban speech)

anyhow, you can also do "if ( bytesFound [i] == 0x01 ) ", it's 2 characters less and actually reads a bit easier

if you're scanning a huge area it would likely pay to employ an algorithm smarter than 'check every single byte' because that's.. not so good..
soak your brain in these wiki pages for a while: http://en.wikipedia.org/wiki/String_searching_algorithm (the boyer-moore algorithm is particularly good)

now im not saying you NEED to go ahead and implement a better algorithm, especially at this point when you just want a working program -- not something fancy. im just trying to get you to take a few steps towards making something that works well instead of something that merely works. this is a programming board after all

sry for resurrecting this but i need help.

I dont know nothing about programming and i need to find an AoB. One guy posted on youtube a cheat video about a game (King's Road) but he wont share his cheat/hack (scritps/oab) so i need help in finding the code.

How can i find it ?
