VBA - Get name of last added sheet - excel

Question

I am looking for a code to get the name of the last added sheet to Excel.
I have tried this...
Sub test()
Dim lastAddedSheet As Worksheet
Dim oneSheet As Worksheet
With ThisWorkbook
Set lastAddedSheet = .Sheets(1)
For Each oneSheet In .Sheets
If Val(Mid(oneSheet.CodeName, 6)) > Val(Mid(lastAddedSheet.CodeName, 6)) Then
Set lastAddedSheet = oneSheet
End If
Next oneSheet
End With
MsgBox lastAddedSheet.Name & " was last added."
End Sub
But it does not really work.

Answer 1

You can't reliably know what sheet was last added, because a sheet can be inserted before or after any existing sheet in a workbook, see Sheets.Add documentation.
Unless you're the one adding it. In which case, all you need to do is capture the Worksheet object returned by the Add method:
Dim newSheet As Worksheet
Set newSheet = wb.Worksheets.Add
Debug.Print newSheet.Name
Extracting the digits from the CodeName isn't going to be reliable either - especially if you assume that every sheet's code name begins with 5 letters. On a German machine, the CodeName of what we see as Sheet1 would be Tabelle1 - but then again the role of that digit is strictly to ensure uniqueness of the names of the VBComponent items in the VBA project, and none of it says it has anything to do with any sort of ordering.

As per #MathieuGuindon his answer, I can't think of any "simple" way to safely return the name of the latest added sheet. However if you willing to sacrifice some designated space in your project to store CodeNames you could try to utilize the Workbook_NewSheet event.
Private Sub Workbook_NewSheet(ByVal Sh As Object)
Dim lr As Long
With Sheets("Blad1")
lr = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
.Cells(lr, 1) = ActiveSheet.CodeName
End With
End Sub
Obviously you need to optimize this to add names when adding sheets during runtime. In this simplified example I manually added the existing sheet "Blad1", and upon adding new sheets, the list grew.
When deleting you can utilize the SheetBeforeDelete event, like so:
Private Sub Workbook_SheetBeforeDelete(ByVal Sh As Object)
Dim ws As Object
Dim lr As Long, x As Long
Dim rng1 As Range, rng2 As Range, cl As Range
With Sheets("Blad1")
lr = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
Set rng1 = .Range("A2:A" & lr)
For Each ws In ActiveWindow.SelectedSheets
For Each cl In rng1
If cl = ws.CodeName Then
If Not rng2 Is Nothing Then
Set rng2 = Union(rng2, cl)
Else
Set rng2 = cl
End If
End If
Next cl
Next ws
End With
If Not rng2 Is Nothing Then
rng2.Delete
End If
End Sub
Now to get the latest added sheet we can refer to the last cell in our designated range:
Sub LastAdded()
Dim lr As Long
With ThisWorkbook.Sheets("Blad1")
lr = .Cells(.Rows.Count, "A").End(xlUp).Row
Debug.Print "Last added sheet is codenamed: " & .Cells(lr, 1)
End With
End Sub
My take on it is that it would be safest to use the CodeName since they are least likely to get changed and are unique. We can also safely keep using our rng variable since there will always be at least one worksheet in your project (and that might just be the designated one if you protect it). Working in this project will now keep track of latest added worksheet.

Sheets could be a Chart or a Worksheet.
You could try use Worksheets instead of Sheets in your code.
sub test()
Dim lastAddedSheet As Worksheet
Dim oneSheet As Worksheet
With ThisWorkbook
Set lastAddedSheet = .WorkSheets(1)
For Each oneSheet In .WorkSheets
If Val(Mid(oneSheet.CodeName, 6)) > Val(Mid(lastAddedSheet.CodeName, 6)) Then
Set lastAddedSheet = oneSheet
End If
Next oneSheet
End With
MsgBox lastAddedSheet.Name & " was last added."
End Sub
