Trying to learn how to use vba to write vba code. Copied this code from
Walkenbach's book to watch how it runs, but when i try to run it, I get the
error message "cant' enter break mode" on
Set NewButton = NewSheet.OLEObjects.Add("Forms.CommandButton.1")

Sub AddSheetAndButton()
Dim NewSheet As Worksheet
Dim Newbutton As OLEObject
Dim Code As String
Dim NextLine As Integer

'Add the sheet
Set NewSheet = Sheets.Add

'Add a CommandButton
Set Newbutton = NewSheet.OLEObjects.Add("Forms.CommandButton.1")
With Newbutton
.Left = 4
.Top = 4
.Width = 100
.Height = 24
.Object.Caption = "Return to Sheet1"
End With

'Add the event handler code
Code = "Sub CommandButton1_Click()" & vbCrLf
Code = Code & " On Error Resume Next" & vbCrLf
Code = Code & " Sheets(""Sheet1"").Activate" & vbCrLf
Code = Code & " If Err <0 Then" & vbCrLf
Code = Code & " MsgBox ""Cannot activete Sheet1.""" & vbCrLf
Code = Code & " End If" & vbCrLf
Code = Code & "End Sub"

With ActiveWorkbook.VBProject.VBComponents(NewSheet.Nam e).CodeModule
NextLine = .CountOfLines + 1
.InsertLines NextLine, Code
End With
End Sub

Have not set any breakpoints in the module.
Any ideas on what could be triggering this?
