将代码添加到Workbook_Open（）

Question

I am trying to write a piece of code that will put the following code into a new excel workbook that has been created. The generated code should be

Private Sub Workbook_Open()
  ThisWorkbook.RefreshAll
End Sub

At the moment I am using the following code, and the new workbook is the active workbook.

Public Sub AddNewModule()

Dim proj As VBIDE.VBProject
Dim comp As VBIDE.VBComponent

Set proj = ActiveWorkbook.VBProject
Set comp = proj.VBComponents.Add(vbext_ct_StdModule)
comp.Name = "MyNewModule"

Set codeMod = comp.CodeModule

With codeMod
  lineNum = .CountOfLines + 1
  .InsertLines lineNum, "Private Sub Workbook_Open()
  lineNum = lineNum + 1
  .InsertLines lineNum, "ThisWorkbook.RefreshAll"
  lineNum = lineNum + 1
  .InsertLines lineNum, "End Sub"
End With

End Sub

Does anyone know where I am going wrong or anything that can help me?

Is this what you are trying (Short And Sweet)?

Option Explicit

Sub Sample()
    With ActiveWorkbook.VBProject.VBComponents(ActiveWorkbook.CodeName).CodeModule
        .InsertLines Line:=.CreateEventProc("Open", "Workbook") + 1, _
        String:=vbCrLf & "ThisWorkbook.RefreshAll"
    End With
End Sub
