Hi,
I created a presentationml from scratch using xmldocument. ( I am emulating it from Matlab, that is why it is somehow simpler than openxml SDK).
I used "ZipFile.CreateFromDirectory" to package all the files and folder. I can start the document by double clicking on it and it works.
But trying PresentationDocument.Open('newdoc.pptx'). I get the error "missing part". I therefore cannot us "validate".
What is weird to me, is that if I do not use "CreatFromDirectory" and that I pass the all the document manually to a manually precreated zipfile, then change the "zip" to "pptx" the PresentationDocument.Open works!
Anyone wo could help me who knows what should be used to zip all the files together that would mimic the manual process?
Thank you,
