......Here a slightly simpler demo, just for Eileens Lounge..., but it’s a real example looking at one of the smaller Folders I have been wanting to investigate.
To do it:
Put the uploaded file, EileenMMDemo.xls, and this folder ,
Movie Maker https://app.box.com/s/cxvc735a85q6az2r3gtb7ii9w2p3jzpf
, in the same place. Then just open the file EileenMMDemo.xls. That file only has one worksheet so the workbook should show just one window of that. In that window make a selection towards the left. Now run the only available macro, Sub PassFolderForReocursing3() , in that workbook which is in the only code module. At the start of the macro it will use the ActiveCell of that window to try and get a single cell range object from the your window Selection . It usually manages that, and goes on to put some results out with that cell at top left. It should look something like this

 Let Reocopy = Reocopy + 1 ' Originally the variable  Reocopy  is zero.  It will become 1 on first entering the macro.  Every time we leave this macro, this number is reduced by 1   So in simple use it will be 1 or zero indicating that a copy is in use.  However, should this macro "Call itself", before its finished , ( the recursion idea ) then the value will be 2  and so on.  So effectively it tells us which copy is running at any time

Here is the main recursion / reoccurring macro 3 corrected slightly for to get the Late Binding working correctly

A couple of things were wrong, or rather one thing wrong, which hid a another problem that should have occurred: I had a few things not declared as objects as they should have been. As I coincidently still had the two library references checked, all still worked, and so did a string variable in this bit Set objWSOFolder = objWSO.Namespace(Pf)
Taking the references off, revealed the problem. Once that was fixed the other problem cropped up https://stackoverflow.com/questions/...88851#77888851

https://eileenslounge.com/viewtopic....315235#p315235

Some Microsoft documentation as of March 2024, here: https://learn.microsoft.com/en-us/of...rror-statement ( Just some of the first bits, relevant to the discussion at https://eileenslounge.com/viewtopic.php?f=30&t=40752 )

On Error statement Article 03/30/2022

Syntax
On Error GoTo line
On Error Resume Next
On Error GoTo 0

The On Error statement syntax can have any of the following forms:

Statement	Description
On Error GoTo line	Enables the error-handling routine that starts at line specified in the required line argument. The line argument is any line label or line number. If a run-time error occurs, control branches to line, making the error handler active. The specified line must be in the same procedure as the On Error statement; otherwise, a compile-time error occurs.
On Error Resume Next	Specifies that when a run-time error occurs, control goes to the statement immediately following the statement where the error occurred and execution continues. Use this form rather than On Error GoTo when accessing objects.
On Error GoTo 0	Disables any enabled error handler in the current procedure.

Remarks
If you don't use an On Error statement, any run-time error that occurs is fatal; that is, an error message is displayed and execution stops.

An "enabled" error handler is one that is turned on by an On Error statement; an "active" error handler is an enabled handler that is in the process of handling an error. If an error occurs while an error handler is active (between the occurrence of the error and a Resume, Exit Sub, Exit Function, or Exit Property statement), the current procedure's error handler can't handle the error. Control returns to the calling procedure.

If the calling procedure has an enabled error handler, it is activated to handle the error. If the calling procedure's error handler is also active, control passes back through previous calling procedures until an enabled, but inactive, error handler is found. If no inactive, enabled error handler is found, the error is fatal at the point at which it actually occurred.

Each time the error handler passes control back to a calling procedure, that procedure becomes the current procedure. After an error is handled by an error handler in any procedure, execution resumes in the current procedure at the point designated by the Resume statement. .........

This is the original coding from SamPi , which confused me a bit for a few reasons
The choice of variable names;
the use of a .xlam file; ( and
the Class module is only part of the story )


Class Module:

Option Explicit
 
Public WithEvents App As Application
 
Private Sub App_WorkbookOpen(ByVal Wb As Workbook)
Dim s As String

s = Wb.Name

If s = "test.csv" Then MyMacro

End Sub

Sub MyMacro()
MsgBox "Yes"
End Sub

ThisWorkbook:

Option Explicit

Dim App             As New App
 
Private Sub Workbook_Open()
     
   Set App.App = Application

End Sub
