New Post: How to check for corrupt presentations/invalid files?

Hi,

I'm writing a small utility with NetOffice that works with PowerPoint presentations. My question is, is there any way I can check if the presentation opened with

PowerPoint.Application.Presentations.Open()

is a valid presentation? I mean, other than just try-catching.
AFAIK the VSTO version of this function returns null if the presentation is not valid (invalid file, corrupt presentation) but NetOffice throws an exception when

Presentation.SlideShowSettings.Run()

is used.
Thanks for your help.
