void COXAutoListBox::DrawItem(....)
{
  ...
  if (lpDrawItemStruct->itemID>=0)
  {
    ...
  }
  ...
}

Most likely this is what should be written here: (lpDrawItemStruct->itemID != (UINT)(-1))

Warning message is:
V547 Expression 'lpDrawItemStruct -> itemID >= 0' is always true. Unsigned type value is always >= 0. UT oxautolistbox.cpp 56
