VBA Early Binding to Late Binding

I use this code to convert PDF Files to Excel.

Private Sub CommandButton2_Click()

Dim setting_sh As Worksheet
Set setting_sh = ThisWorkbook.Sheets("Tabelle1")

Dim pdf_path As String
Dim excel_path As String

pdf_path = setting_sh.Range("E11").Value
excel_path = setting_sh.Range("E12").Value

Dim fso As New FileSystemObject
Dim fo As Folder
Dim f As File

Set fo = fso.GetFolder(pdf_path)

Dim wa As Object
Dim doc As Object
Dim wr As Object

Set wa = CreateObject("word.application")

'Dim wa As New Word.Application
wa.Visible = True
'Dim doc As Word.Document

Dim nwb As Workbook
Dim nsh As Worksheet
'Dim wr As Word.Range

For Each f In fo.Files
Set doc = wa.documents.Open(f.Path, False, Format:="PDF Files")
Set wr = doc.Paragraphs(1).Range
wr.WholeStory


Set nwb = Workbooks.Add
Set nsh = nwb.Sheets(1)
wr.Copy

nsh.Paste
nwb.SaveAs (excel_path & "\" & Replace(f.Name, ".pdf", ".xlsx"))

doc.Close False
nwb.Close False
Next

wa.Quit

MsgBox "Done"

End Sub

The problem is, other people also want to use this function, but they don’t understand to how to add the Microsoft Scripting Runtime Reference in your VBA project. I tried to convert it to late binding, but it fails all the time. Can someone help me?

Thanks.

>Solution :

1. The next code will automatically add the necessary reference:

Sub addScrRunTimeRef()
  'Add a reference to 'Microsoft Scripting Runtime':
  'In case of error ('Programmatic access to Visual Basic Project not trusted'):
  'Options->Trust Center->Trust Center Settings->Macro Settings->Developer Macro Settings->
  '         check "Trust access to the VBA project object model"
  Application.VBE.ActiveVBProject.References.AddFromFile "C:\Windows\SysWOW64\scrrun.dll"
End Sub

2. To not need it, use:

Dim fso As Object, fo as Object, f as Object
set fso =CreateObject("Scripting.FileSystemObject")
