ExcelBanter - Unique Values in a Column

Here is some code that reference the range selected by the user (column, row,
just a few cells,...) and returns a new sheet with the unique items. There is
also some code to find the duplicate items... To use this code you need to
refence the project to "Microsoft Scripting Runtime" library.

Private Sub GetUniqueItems()
Dim cell As Range 'Current cell in range to check
Dim rngToSearch As Range 'Cells to be searched
Dim dic As Scripting.Dictionary 'Dictionary Object
Dim dicItem As Variant 'Items within dictionary object
Dim wks As Worksheet 'Worksheet to populate with
unique items
Dim rngPaste As Range 'Cells where unique items are
placed

'Create range to be searched
Set rngToSearch = Intersect(ActiveSheet.UsedRange, Selection)
If rngToSearch Is Nothing Then Set rngToSearch = ActiveCell

'Confirm there is a relevant range selected
If Not rngToSearch Is Nothing Then
'Create dictionay object
Set dic = New Scripting.Dictionary

'Populate dictionary object with unique items (use key to define
unique)
For Each cell In rngToSearch 'Traverse selected range
If Not dic.Exists(cell.Value) And cell.Value < Empty Then
'Check the key
dic.Add cell.Value, cell.Value 'Add the item if unique
End If
Next

If Not dic Is Nothing Then 'Check for dictionary
Set wks = Worksheets.Add 'Create worksheet to populate
Set rngPaste = wks.Range("A1") 'Create range to populate
For Each dicItem In dic.Items 'Loop through dictionary
rngPaste.NumberFormat = "@" 'Format cell as text
rngPaste.Value = dicItem 'Add items to new sheet
Set rngPaste = rngPaste.Offset(1, 0) 'Increment paste range
Next dicItem
'Clean up objects
Set wks = Nothing
Set rngPaste = Nothing
Set dic = Nothing
End If
End If

End Sub

Private Sub GetDuplicateItems()
Dim cell As Range 'Current cell in range to check
Dim rngToSearch As Range 'Cells to be searched
Dim dic As Scripting.Dictionary 'Dictionary Object
Dim dicItem As Variant 'Items within dictionary object
Dim wks As Worksheet 'Worksheet to populate with
unique items
Dim rngPaste As Range 'Cells where unique items are
placed
Dim aryDuplicates() As String
Dim lngCounter As Long

'Create range to be searched
Set rngToSearch = Intersect(ActiveSheet.UsedRange, Selection)
If rngToSearch Is Nothing Then Set rngToSearch = ActiveCell
lngCounter = 0

'Confirm there is a relevant range selected
If Not rngToSearch Is Nothing Then
'Create dictionay object
Set dic = New Scripting.Dictionary

'Populate dictionary object with unique items (use key to define
unique)
For Each cell In rngToSearch 'Traverse selected range
If Not dic.Exists(cell.Value) And cell.Value < Empty Then
'Check the key
dic.Add cell.Value, cell.Value 'Add the item if unique
Else
ReDim Preserve aryDuplicates(lngCounter)
aryDuplicates(lngCounter) = cell
lngCounter = lngCounter + 1
End If
Next

If lngCounter 0 Then 'Check for values
Set wks = Worksheets.Add 'Create worksheet to populate
Set rngPaste = wks.Range("A1") 'Create range to populate
For lngCounter = LBound(aryDuplicates) To UBound(aryDuplicates)
'Loop duplicates
rngPaste.NumberFormat = "@" 'Format cell as text
rngPaste.Value = aryDuplicates(lngCounter) 'Add items to
new sheet
Set rngPaste = rngPaste.Offset(1, 0) 'Increment paste range
Next lngCounter
'Clean up objects
Set wks = Nothing
Set rngPaste = Nothing
Else
MsgBox "There are no duplicate items in the selected cells.",
vbInformation, "No Duplicates"
End If
Set dic = Nothing
End If
End Sub

I have a table that has a column of states. I have formula that will give me
a list of all the unique values in that column:

=INDEX($A$2:$A$2208,MATCH(0,COUNTIF($B$2:B2,$A$2:$ A$2208),0))

I'd like to do the same with some vba code to create a new worksheet with
the values that it creates. Any suggestions?
