PlateStars.Sort() Method

Sort the collection in the given order and direction.

Syntax

PlateStars.Sort(Order, Direction, RightAscension, Declination)

The method syntax has these parts:

Part	Description
Order (SortOrder)	The order in which to sort the collection
Direction (SortDirection)	The direction in which to sort the collection (optional, default = ppSortAscending)
RightAscension (Double)	The right ascension of the reference point for sorting by distance (hours, optional)
Declination (Double)	The declination of the reference point used for sorting by distance (degrees, optional)
Return (Nothing)	Does not return a value.

Remarks

The RightAscension and Declination parameters are ignored, and may be omitted, for all sort orders ecxept ppSortByDirection. The Direction parameter may be omitted. It defaults to ppSortAscending. If a parameter is omitted fro the middle of the list, you must supply placeholder commas.

It is possible to create several PlateStars collections of the same type, each having a different sorting order.
