Sub IntersectOppositeExample()

'Example of how to select the mutually exclusive
'portion(s) of two ranges that intersect in Excel
Dim Rng1, Rng2, AllRange, ExcludeRange As Range
Dim NewRg, CurrCell, AntiRange As Range

On Error Resume Next
Set Rng1 = Application.InputBox( _
prompt:="Select 1st Range of Cells
to Evaluate", Type:=8)
Set Rng2 = Application.InputBox( _
prompt:="Select 2nd Range of Cells
to Evaluate", Type:=8)
Set AllRange = Union(Rng1, Rng2)
Set ExcludeRange = Intersect(Rng1, Rng2)


For Each CurrCell In AllRange.Cells
If Intersect(CurrCell, ExcludeRange) Is Nothing Then
If NewRg Is Nothing Then
Set NewRg = CurrCell
Else
Set NewRg = Union(NewRg, CurrCell)
End If
End If
Next
Set AntiRange = NewRg
AntiRange.Select
End Sub
