Interesting that your original patch made things work at all... you set the
pParameters variable, which is then promptly forgotten upon return from the
function.  In effect your original patch does nothing... so why it would make
things work is beyond me :)

In any case, your second patch looks much better, but as Robert said, can't you
simplify it with a memcpy() instead of an exhaustive list of the structure
members?  That is, assuming This->createParms and pParameters are of the same
type you could just do:

  memcpy(pParameters, &This->createParms, sizeof(D3DDEVICE_CREATION_PARAMETERS));
  return D3D_OK;

This is much less error-prone than a list of structure members.
