In PowerPoint 2007 and using VBA, how can I get the placeholder shape on a Slide Master layout that is the "master" for a placeholder shape on the slide?
I am currently using a loop to compare the position and size of the slide placeholder with the position and shape of each placeholder shape in the slide's layout, but this isn't fool-proof. For example, if the placeholder shape is moved on the slide, its position may no longer match the position of any placeholder shapes in the slide's layout. I could reapply the slide's layout to snap placeholders back into position, but that's not what I want to do.
Something in the object model like Shape.Master would be ideal but, of course, that doesn't exist.
