Thank me is you use it.

Nice Assembly Pro !

Can u make a hook for Reset ?
And works the Present hook on windows xp or only vista & 7 ?

Reset Found at: 0x732D7345

Code:

DWORD ResetRet;
__declspec(naked) void myMidReset()
{
	static LPDIRECT3DDEVICE9 pDevice;
	static D3DPRESENT_PARAMETERS* pPresentationParameters; 

	__asm mov dword ptr ss:[ebp-10],esp; //Replace Code

	__asm mov esi, dword ptr ss:[ebp+0x8]; //Move esi to real device
	__asm mov pDevice, esi; //Move Device to esi

	__asm mov eax, dword ptr ss:[ebp-0xC]; //Move esi to real state
	__asm mov pPresentationParameters, eax; //Move State to esi

	__asm jmp ResetRet; //jmp to hook
}

Code:

DWORD ResetHook = ( vTable[16] + 0xD );

ResetRet     = DetouringFunction( ( BYTE* ) ResetHook   , ( BYTE * ) myMidReset, 5 );
