Probably not, the trick is that ComponentList exposes a collection of TComponent references. So, in order to use them as whatever you actually stored in the list instead of just TComponents you have to do some typecasting: with (mCommands[index] as TMacroCombo) do begin align := alLeft; ItemIndex := 0; etc... end; Make sense?
