c++ builder combobox AddObject,该怎么解决

c++ builder combobox AddObject
int i_yileiid=0;
  while(!ADOQ_yilei->Eof)
  {
  i_yileiid=ADOQ_yilei->FieldByName("id")->AsInteger;
  ComboBox_yilei->Items->AddObject(ADOQ_yilei->FieldByName("name")->AsString,(TObject *)i_yileiid);
  ADOQ_yilei->Next();
  }

请教高手这块怎么释放内存，谢谢！

[解决办法]
ComboBox1->Items->Delete(i);
就释放了吧
