void Init_3D()

    lp3D->CreateDevice(D3DADAPTER_DEFAULT,D3DDEVTYPE_HAL,main_window_handle,D3DCREATE_SOFTWARE_VERTEXPROCESSING,&dpp,&lp3DDevice); 
}

Leider ergibt dieser Code, diese Fehlermeldung:

1>sfad.obj : error LNK2019: Verweis auf nicht aufgelöstes externes Symbol "_Direct3DCreate9@4" in Funktion ""void __cdecl Init_3D(void)" (?Init_3D@@YAXXZ)".

Sieht so aus als hättest du das lib von DirectX vergessen.
