int value = *ptr; |

| Thanks for the Reply, is it really that simple? Don't you have to get the Process or something like that?

| Yeah, pointers are easy. You just point and read the value at the address.

C/C++ has a direct access to the memory
that's why you don't have to use readprocessmemory
unless you want to read other process's memory

ReadProcessMemory to read other process' memory.
Jany's code to read your process' memory.
You can also inject a DLL to use Jany's code in any process.

| ReadProcessMemory and WriteProcessMemory are hooked by game security systems, so if you're asking because of game cheats, you should use DLL Injection.

First you want to do a VirtualProtect hookhop because it locally hooked on most anti-hacking systems.
Like so:
| Code: |
DWORD VirtualAddress = (DWORD)GetProcAddress(GetModuleHandleA("kernel32.dll"), "VirtualProtect") + 5;
BOOL WINAPI VirtualProtectX(LPVOID lpAddress, SIZE_T dwSize, DWORD flNewProtect, PDWORD lpflOldProtect)
{
_asm {
mov edi,edi
push ebp
mov esp, ebp
jmp [VirtualAddress]
}
}
|
Now do this:
| Code: |
DWORD Protection;
VirtualProtectX((LPVOID) 0xAddress, 4, PAGE_EXECUTE_READWRITE, &Protection);
// if your editing a 4 byte address
*(DWORD*) 0xAddress = 100;
|
Thats it, it works like that. Dont listen to anybody that tells you to just derefence the address then typecast it, it wont work. You need to give read/write protection to the address.

Why would he want to read from an address which is unreadable in normal circumstances ? It's not really likely to store a variable, is it ? You make no sense

Your confused, what i'm doing is for example, if I want to edit the address 0x00400000, and lets stay its a 16-bit address, and I wanted its value to be one.
| Code: |
DWORD Protect;
VirtualProtectX((LPVOID) 0x00400000, 4, PAGE_EXECUTE_READWRITE, &Protect);
// To protect the address in order for us to edit it now..
*(WORD*) 0x00400000 = 1;
// What i'm doing is dereferencing the address with the * and typecasting it to a WORD (which is 16-bits) then making it equal to the value 1. This works 100% when I tried it. |

Well I don't need to write to an Address, I just need to read from it .
(As the Title of the Thread/Topic says)
Anyways thank you for your Post.
I'll need this some time  .
