Excel Open XML and OLE RRS feed

  • Question

  • I want to get a starting point how is it possible to use OLE and keep Open XML (compressed XML) as the persistency format instead of Structured Storage.

    Classical OLE only permits to ose IStorage, IStream etc. but when a Visio Document inserted as an object to Excel and the file saved with new format, the new file contains the entire Visio file (vsdm) as Open XML format.

    I want to do the same thing as Excel doing. After creating the Visio as an Embedded OLE object I want to save my out put as compressed xml file that contains the Visio file as vsdm (compressed xml).
