Description

Sorts one-dimentional array in ascending / descending order.

Implementation

Public Function ArraySort(ByRef dvArray, ByVal boolAscending)
  Dim Iter, Jter, aValue
  If Not isArray(dvArray) Then
    dvArray = Array(dvArray)
    ArraySort = dvArray
  End If
 For Jter = 0 To UBound(dvArray)
  For Iter = 0 To UBound(dvArray)-1
   aValue = dvArray(Iter)
   If aValue > dvArray(Iter+1) Then
    If boolAscending Then
     dvArray(Iter) = dvArray(Iter+1)
     dvArray(Iter+1) = aValue
    Else
     'do nothing
    End If
   Else
    If boolAscending Then
     'do nothing
    Else
     dvArray(Iter) = dvArray(Iter+1)
     dvArray(Iter+1) = aValue
    End If
   End If
  Next
 Next
 ArraySort = dvArray
End Function
