AutoNumbering in Visio and PPT

Is there a way to autonumber when you open up visio or ppt? I need a number to count on the slide in ppt and in a shape in visio. I have tried insert excel that has a macro that will do what I want it to do but I can't get it to work when you open up visio/ppt. All I want is a number count to display when I open up the d开发者_Go百科ocument.

You can do this in PowerPoint:

1. Insert > Header/Footer...
2. Check the Slide Numbers box.

PowerPoint doesn't have any mechanism for running code automatically in response to a user opening a document file. You pretty much need to write an add-in that traps and responds to events like users opening a file, and the add-in must be installed on each user's PC where you expect this to work.

For Visio, this this MSDN Article: Visio: How to Use Background Pages to Set Up Automatic Page Numbering may be of assistance.
