Help: in making a 'CF UD Hook' [D3D]

Some Old Hooks: Maybe you can make it to work, maybe it's not possible to make it UD! -> I don't know
- @coders, Help me with making a hook for CF [specific D3D]

Code:

void VirtualHook( )
{
    Dx9Hook("d3d9.dll");
    DWORD dwDrawIndexedPrimitive = GetAddressPtr(82);
    pReset = (oReset)DetourCreateE9((DWORD)vTable[16],(DWORD)myReset, SIZEOF_JMP_REL);
    pPresent = (oPresent)DetourCreateE9((DWORD)vTable[17],(DWORD)myPresent, SIZEOF_JMP_REL);
    pDrawIndexedPrimitive = (oDrawIndexedPrimitive)DetourCreateb8((DWORD)vTable[82],(DWORD)myDrawIndexedPrimitive, 

12);
    while(8)
 {
    if(memcmp((VOID *)vTable[82], (VOID *)"\x8B\xFF", 2) == 0 )
 {
  pDrawIndexedPrimitive = (oDrawIndexedPrimitive)DetourCreateb8((DWORD)vTable[82],(DWORD)myDrawIndexedPrimitive, 12);
 }
 Sleep(800);
 }
}

I heart VTable Index 82: [U]DrawIndexedPrimitive -> Index 12:[/U => GameGuard didn't scan it.
So it make it Undetected, but for crossfire its more difficult i think.

I Going to make VTable Hook.
So plss help me!

Virtual Hook( Vtable[82],
4,
PAGE_EXECUTE_READWRITE,
&Old )
& more.. pls help!
