How To Mimic ThisPresentation In VBA For PowerPoint

What This VBA Code Does

It's unfortunate that the Microsoft developer's did not include a ThisPresentation class in PowerPoint's VBA language. However, there is a way to simulate this functionality by referencing the Presentation's file name. Since users can only have unique file names open simultaneously, this method can serve as an alternative. BEWARE though, because if you change the PowerPoint's file name your macro will not function as intended. But because I'm nice, I'll show you how to put an Error Handler in the VBA code so your user's do not get confused if the name is accidentally changed!

Sub Mimic_ThisPresentation()
'PURPOSE: Show how to mimic the functionality of ThisPresentation
'SOURCE: www.TheSpreadsheetGuru.com/The-Code-Vault

Dim ThisPresentation As Presentation
Dim ThisFile As String

'What is the name of this file?
  ThisFile = "Presentation1.pptx"

'Set Variable to Presentation via Filename
  On Error GoTo NotFound
    Set ThisPresentation = Application.Presentations(ThisFile)
  On Error GoTo 0
  
'Do Something...(ie add Callout shape to first slide)
  ThisPresentation.Slides(1).Shapes.AddCallout msoCalloutOne, 50, 50, 50, 50

Exit Sub

'Error Handler
NotFound:
  MsgBox "There is no file currently opened with the name:  " _
    & ThisFile & vbNewLine & "Please check to see if the file" _
    & " was renamed or modify the VBA code.", vbCritical, "File Not Found"

End Sub
