Ambiguity between 'IPictureDispPtr' and 'Cwuicontrolslib_tlb::IPictureDispPtr'

소스는.....

void __fastcall set_TypeButtonPicture(IPictureDispPtr /*[VT_USERDEFINED:1]*/   <= 여기
Value)
  {
    _TDispID _dispid(/* TypeButtonPicture */ DISPID(135));
    TAutoArgs<1> _args;
    _args[1] = (LPDISPATCH) /*[VT_DISPATCH:1]*/ (IPictureDisp* /*[C2]*/)Value;  <= 여기
     OlePropertyPut(_dispid, _args);
  }

  IPictureDispPtr /*[VT_USERDEFINED:1]*/ __fastcall get_TypeButtonPicture()   <= 여기
  {
    _TDispID _dispid(/* TypeButtonPicture */ DISPID(135));
    TAutoArgs<0> _args;
    OlePropertyGet(_dispid, _args);
    return (IPictureDisp* /*[C3]*/)(LPDISPATCH)_args.GetRetVariant();         <=여기

}
                 .
                 .

  __property   IPictureDispPtr CursorIcon = {read = get_CursorIcon, write =      <=여기

에러가 발생하고 이런 것이 26개나 발생합니다. ::나 Cwuicontrolslib_tlb::를 앞에 붙여도..
