I have this solution to prapogate some code to all Excel files in a folder. It errors at:

TargetWorkbook.VBProject.VBComponents.Item("ThisWorkbook").CodeModule.InsertLines 99999, Code

saying: "Application-defined or object-defined error."

Here is the code:

Public Sub PropagateTheCode()
   Dim FileName As String
   Dim TargetWorkbook As Workbook
   Dim Code As String
   Const Folder = "C:\Documents and Settings\meghtebas\Desktop"
   Code = "Private Sub Workbook_Open()"
   Code = Code & vbCrLf & "   MsgBox ""Code is here!"""
   Code = Code & vbCrLf & "End Sub"
   FileName = Dir(Folder & "\*.xls")
   Do While FileName <> ""
      Set TargetWorkbook = Workbooks.Open(Folder & "\" & FileName)
      TargetWorkbook.VBProject.VBComponents.Item("ThisWorkbook").CodeModule.InsertLines 99999, Code
      TargetWorkbook.Close True
      FileName = Dir
End Sub

Do you know how this could be corrected.

Thank you.
