How to provide VBA access for a modify password protected read only PowerPoint file? -

I am trying to create an independent non-editable version of a Power Point slide that shows how to use VBA Can be done Slide is an interactive stopwatch for making a slide very dynamic and there is a video about it here.

The VBA is used to modify different sizes on slides based on the Windows API Timer

In the free version, run the functionality of VBA Should, but set the presentation so that slide objects can not be edited.

This is what I've tried so far:

1 - Setting the modified password on a ppsm version of the file. Problem : VBA can not modify the properties of objects on the slide when the presentation is opened in read only mode.

2 - Using VBA to save the temporary write version of the file. Problem : Once the presentation is opened as a read only, it is not possible to use VBA to provide this password and then save it as a convertible file.

3 - To create a separate PPSM file with an action to run a macro to open the password protected stopwatch deck, which has a shape on it. Problem : PowerPoint 2013 causes VBA code crash to open a password-protected presentation (available since PowerPoint 2010):

  dim oPVW ProtectedViewWindow Dim oPres Presentation Set as oPVW = ProtectedViewWindows.Open (File Name, ReadPassword) oPres = PVW.Edit Set (ModifyPassword)   
 4 - In another presentation as a slide object Stopwatch embedded PPSM file so that the user can click on save it and do not edit it. New  problem :.? Due to the creation of a slide show from an embedded object, VBA does not cause the code to be run  
 Do anyone need any idea how the need can be addressed   < P> 
 
 
 
 
  
 One approach:  
 Let them edit their hearts Size the content but warn them that if they do, your code will decline to run.  
 Your code can test any combination of properties of your shape: height, width, top, left, color, text and so on. And refuse to run it if one of those properties has been replaced by the size given by you.
