Eu consigo usar uma array no C.E normalmente:

?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? DB 0F 49 40 35 FA 8E 3C ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? DB 0F C9

\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x DB\x0F\x49\x40\x35\xFA\x8E\x3C\x00\x00\x00\x00\x00 \x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x 00\x00\x00\xDB\x0F\xC9

????????????xxxxxxxx????????????????????xxx

Code:

const bool bDataCompare(const BYTE *pData, const BYTE *bMask, const char *szMask)
{
	for (; *szMask; ++szMask, ++pData, ++bMask)
		if (*szMask == 'x' && *pData != *bMask)
			return 0;
	return (*szMask) == NULL;
}

DWORD FindPattern(DWORD dwModule, DWORD dwLen, BYTE *bMask, char *szMask)
{
	for (DWORD i = 0; i < dwLen; i++)
		if (bDataCompare((BYTE *)(dwModule + i), bMask, szMask))
			return (DWORD)(dwModule + i);
	return 0;
}

Code:

#define WEAPONMGR_PATTERN "\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xDB\x0F\x49\x40\x35\xFA\x8E\x3C\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xDB\x0F\xC9"

#define WEAPONMGR_MASK "????????????xxxxxxxx????????????????????xxx"

ADDR_WEAPONMGR =
		FindPattern((DWORD)GetModuleHandleA("CShell.dll"), 0xFFFFFF,
		(PBYTE)WEAPONMGR_PATTERN, (char *)WEAPONMGR_MASK);

	char szMyDword2[10];
	sprintf(szMyDword2, "0x%08x", ADDR_WEAPONMGR);



	MessageBox(0, szMyDword2, TEXT("weapon mgr"), MB_OK);

Alguém sabe o que ta de errado? e são várias AoB's que funcionam no C.E mas na DLL não =/

Obrigado desde já \õ

Procurando no olly, seu pattern joga pro endereço do WeaponMgr diretamente. Eu prefiro pegar a localização de um pointer.

Code:

WeaponMgr = FindPattern(CShell, 0xFFFFFF, (PBYTE)"\x8B\x0D\x00\x00\x00\x00\x8B\x04\xB1\xD9\xE8", "xx????xxxxx");
if (WeaponMgr != NULL)
	WeaponMgr = *(DWORD*)(WeaponMgr + 0x2);

Isso irá retornar o endereço do WeaponMgr sem ter um pattern gigante para lagar o programa.

FindPattern(CShell, 0xFFFFFFF..
