I dont understand Pascal. Forgive me. Please tell if it is ok on C++ if you

may:

bool _stdcall RVIsEmpty(TCustomRichView *p_RView)

{

  assert(p_RView);

  return p_RView->ItemCount == 0 ? false :

  ((p_RView->ItemCount == 1) && (p_RView->GetItemStyle(0) == 0)) &&

    p_RView->GetItemText(0).IsEmpty();

}
