.dll injection question...

[nucl34r]

How exactly do you write memory to a process by using a .dll I've done this the external way (using WriteProcessMemory).

[why06]

By using takes a memcpy() function. It takes a couple parameters:
memcpy, wmemcpy (CRT)
memcpy(destination, source, num_of_bytes);

ofcourse you may have to change the protection of memory in order to write to it. That's what VirtualProtect() is for. VirtualProtect Function (Windows)

and I think you should change back the protection once you change whatever address you wan, but Im not sure. =/

yep that why sai is true

[Retoxified]

*(DWORD*)0x138732 = 541;

or

void PatchMem(LPVOID dwAddress, LPVOID bytes, DWORD dwSize)
{
	DWORD flOldProtect = 0;
	VirtualProtect((void*)dwAddress, dwSize, PAGE_EXECUTE_READWRITE, &flOldProtect);
	memcpy((void*) dwAddress, bytes, dwSize);
	VirtualProtect((void*)dwAddress, dwSize, flOldProtect, &flOldProtect);
}

then use that like

unsigned long* fireRecoil = 0x387489;
BYTE fireRecoilPatch[2] = {0x25, 0x5F};
PatchMem(fireRecoil, fireRecoilPatch, 2);
