I am having trouble getting this code to work. When I call the function
1. Is the INVal the array I am passing?
2. The "Dim To Sort" line doesn't make sense to me. Don't you have to Dim
it as something?
Thanks...


Option Explicit

Public Function BubbleSort(InVal As Variant, Optional Order As String =
"Asc")
Dim fChanges As Boolean
Dim iElement As Long
Dim iElement2 As Long
Dim temp As Variant
Dim ToSort

If TypeName(InVal) = "Variant()" Then
ToSort = InVal
Do
fChanges = False
For iElement = LBound(ToSort) To UBound(ToSort) - 1
If ((Order = "Asc" And ToSort(iElement) ToSort(iElement +
1)) Or _
(Order < "Asc" And ToSort(iElement) < ToSort(iElement +
1))) Then
'Swap elements
temp = ToSort(iElement)
ToSort(iElement) = ToSort(iElement + 1)
ToSort(iElement + 1) = temp
fChanges = True
End If
Next iElement
Loop Until Not fChanges
ElseIf TypeName(InVal) = "Range" Then
ToSort = InVal
ReDim temp(LBound(ToSort, 2) To UBound(ToSort, 2))
Do
fChanges = False
For iElement = LBound(ToSort) To UBound(ToSort) - 1
If ((Order = "Asc" And ToSort(iElement, 1) ToSort(iElement
+ 1, 1)) Or _
(Order < "Asc" And ToSort(iElement, 1) <
ToSort(iElement + 1, 1))) Then
'Swap elements
For iElement2 = LBound(ToSort, 2) To UBound(ToSort, 2)
temp(iElement2) = ToSort(iElement, iElement2)
ToSort(iElement, iElement2) = ToSort(iElement + 1,
iElement2)
ToSort(iElement + 1, iElement2) = temp(iElement2)
Next iElement2
fChanges = True
End If
Next iElement
Loop Until Not fChanges
End If
BubbleSort = ToSort
End Function



Sub testbubblesort()
Dim ary
ary = Array(1, "Bill", 4, 3, 6, "Alan", "Barry", 2)
ary = BubbleSort(ary)
ary = BubbleSort(Range("B1:D10"))
End Sub

How do you sort an array and then do a binary search on an array in VBA?
Also, can you assign pointers to the array? How?
