Properties of type: TForm, TDataSet, TField


Does anybody know how to handle setting of the properties like TForm,
TDataSet, TField
in component in designing mode. I need do it in my own form, not in the
Object Inspector.
I only know how to do it for TDataSet, TField in the Object Inspector (using
TDataLink ...) but
it isn't the same.

- Thanks for help and ... sorry for my English !
