IT will allegedly be included in VB7 but is not there yet. The alternatives completely depend on the individual scenario. It is almost impossible to give a simple answer to such a complex question.

You will need to add your requested parameters to the collection and reffer them by the parameter name.
(use the parameter name as a Key to the collection and then you be able to reffer it easly).
