struct VariableObject{
   int First;
   double Second;
   enum {FirstVar, SecondVar};

int wmain(int argc, wchar_t* argv[])
   const char16_t *message;
   CODBPP database;
   if(database.BeginTransaction() == NO_ERROR
   && database.OpenTable(TABLE_ONE) == NO_ERROR
   && database.ReadObject(TABLE_ONE,CODBPP::FIRST) == NO_ERROR
   && database.GetVariableField(TABLE_ONE,VariableObject::SecondVar,&message) == NO_ERROR)
   else if(database.GetErrorMessage(&message) == NO_ERROR) MessageBox(message);
