I'm trying to read out the Ole Data from a Visio Document.
I understand that the data is stored in Shape.ForeignData. But I also need to know what kind of object it is (Excel, Powerpoint, xml, etc).
For Cells, Words, Slides there are Apis there, that allows me to read the File Extension or the Ole ProgId. Is it also possible with Diagrams?
Thanks for your help.
