To solve this issue, some time ago Bob McClellan and I put together something called PresentationBuilder which deals with these inter-dependencies. Hi Peter, I think that the problem here is that there are a lot of inter-dependencies in PresentationML, and the Open XML SDK validator, while it checks for a number of them, doesn't catch them all. Actually, the template and the pre-created presentation works together with other files.īest Regards Peter Karlström Midrange AB, Sweden Is there anything wrong with my code, or am I missing to check something when I merge the Slidemaster to the presentation?Ī lot of other pre-created presentations and templates works fine to merge, but the combination that can be downloaded above won't work. If anybody would like to test with my sample files, they can be downloaded from

SlidePart.DeletePart(slidePart.SlideLayoutPart) LayoutType = GetSlideLayoutType(slidePart.SlideLayoutPart) ' Determine the slide layout type for each slide. If (Not (slidePart.SlideLayoutPart) Is Nothing) Then ' Remove the slide layout relationship on all slides.įor Each slidePart As SlidePart In presentationPart.SlideParts

If we repair the presentation, save it and use the comparison tool, there are a lot of differences, but they all seem to be of the "renaming sort" if slidelayout parts.
Nothing wrong is found in validation which can explain the repair-message in Powerpoint. Now, when we use Open XML Productivity tool to validate the file, the validation result only consists if the "smtclean is not declared" messages, which seems to be shown for every type of presentation you try to validate, even a new blank presentation The strange thing is that with certain combination of pre-created presentation and template presentation, the resulting file doesn't open in Powerpoint without asking for repair. In most cases this works fine and the presentations opens nicely in Powerpoint. We create the presentation using another pre-created presentation on which we apply the SlideMaster from a template presentation. We run into problems when creating Powerpoint-presentations in some scenarios. We have a webservice creating Office documents using Open XML SDK developed in VS 2010.
