Returns the first member of this collection that matches the find criteria. If no item is found, it returns "Nothing", which you can use to trap errors.
Parameter ParameterCollection.Find( String in_filter ); |
oReturn = ParameterCollection.Find( [Type] ); |
Object (type varies according to find criteria).
