Detoured function not being called

I'm using visual studio 2003 with CDetour.
This time I cannot give a SSCE so this is what I've done:

LPDIRECT3D9 d3d;
LPDIRECT3DDEVICE9 d3ddev;

CDetour CreateDevice_Det;
IDirect3D9* Direct3DCreate9_Hook( UINT SDKVersion )
{
        MessageBox( GetForegroundWindow(), "Direct9 Create Hooked", "dForce.dll", MB_OK );
        d3d = Direct3DCreate9(D3D_SDK_VERSION);
        return d3d;
}

BOOL WINAPI DllMain(HINSTANCE hInst,DWORD reason,LPVOID reserved)
{
    switch(reason)
    {
        case DLL_PROCESS_ATTACH:
        {
            HMODULE hd3d = GetModuleHandle( "d3d9.dll" );
            if( hd3d == 0 )
            {
                MessageBox( GetForegroundWindow(), "d3d9.dll still not loaded", "dForce.dll", MB_ICONSTOP );
                return FALSE;
            }
            DWORD lpAddr = (DWORD)GetProcAddress( hd3d, "Direct3DCreate9" );
            if( lpAddr == 0 )
            {
                MessageBox( GetForegroundWindow(), "could not find valid d3d9.dll create device address", "dForce.dll", MB_ICONSTOP );
                return FALSE;
            }
            CreateDevice_Det.Detour( (LPBYTE)lpAddr, (LPBYTE)Direct3DCreate9_Hook );
            CString strDetoured;
            strDetoured.Format( "CreateDevice Hooked! Address: %x", (LPVOID)lpAddr );
            MessageBox( GetForegroundWindow(), strDetoured, "dFoce.dll", MB_ICONINFORMATION );
        }break;
    }
    return TRUE;
}

I have hooked another functions such as LoadLibrary (from kernel32.dll) with success the same way, this dll is of course loaded before Direct3DCreate9 on the main program, I have also tried this on a console wi32 program but my hooked function is still not called. Am I missing something?

Apparently CDetour is not related to MS Detours at all (found it googling for ms detours).

After you CreateDevice_Det.Detour( ...) you must apply the detour, it's not auto. CreateDevice_Det.Apply().

I dont see detourTransactionBegin(), DetourUpdateThread() and DetourTransactioncommit() calls here. API Hooking with MS Detours have a good explaination.
