PowerPoint PresentationCloseFinal event

The Microsoft PowerPoint on macOS does not fire the PresentationCloseFinal event. This event should be fired when the presentation document is really closed.

The event is fired on PowerPoint on Windows.

Installing the macro file

Use Microsoft PowerPoint for Mac, choose Tools > PowerPoint Add-ins... dialog to add the compiled PresentationCloseFinalAddin.ppam file to the application.

Bug report

The macro file is an addin which can be added to the Microsoft PowerPoint app on Windows or on Mac.

The macro sets handlers for various events in the presentation lifecycle:

• PresentationBeforeClose
• PresentationClose
• PresentationCloseFinal

When user closes the presentation document, PowerPoint will fire the PresentationClose event. When document is unsaved, PowerPoint will display a dialog box to save the file after this event handler code was executed.

If user choses to cancel the save file dialog box, the presentation will still be opened and user can work with it. This makes the PresentationClose unsuitable to clean up resources.

The PowerPoint 2010 on Windows added new event PresentationCloseFinal which is called if the presentation document is really closed.

It is the right event to clean up any unmaganed resources the macro or add-in may be working with.

Expected behavior

The PresentationCloseFinal should be fired on PowerPoint on macOS at the same point when Windows version of PowerPoint does it.

Actual behavior

The PresentationCloseFinal is never fired on PowerPoint on macOS.

Compiling the source code

1. Install .NET 8 SDK
2. Install vbamc tool
3. Compile addin with make

brew install make
brew install --cask dotnet-sdk
dotnet tool install --global vbamc

cd src
make

The compiled PresentationCloseFinalAddin.ppam file will be in the src/bin directory.
