How to automate PowerPoint spell-check?

I have 开发者_如何学运维searched high and low to find some way to try to automate spell-check in VBA for PowerPoint, but have not been able to uncover anything. I'm looking for similar functionality to what Word and Excel offer in automating spell-check, but for PowerPoint

The routine I'm after would be like (psuedo):

For Each Mispelling in ActivePresentation.Mispellings
    Mispelling.IgnoreAll = True
Next
ActivePresentation.Save

Any help would be appreciated!

Progammatically checking spelling in PowerPoint is not available. It's rather unfortunate as I've needed this myself before too (to bulk spell-check multiple PPTs programmatically). At best you could interop with Word and send the text there to be spell-checked and then send back to PowerPoint, but I image this would be rather clunky.
