Read binaries of objects inserted into a Word document

[Prasad More]

Following types of objects can be inserted into Microsoft Word Document
1. Adobe Acrobat Document
2. Bitmap Image
3. Media Clip
4. MS Office Excel Worksheet
5. MS Office Word Document

When objects of above types are inserted into a Word Document, binaries for
inserted objects are stored in "embeddeings" folder inside the package for
Word document.

I want to write an application which will read binaries of objects inserted
into a Word document while the document is open using Word Object Model and
IDataObject interface. The object can be of any type from the above mentioned
types.
e.g. If I insert a Adobe Acrobat Document i.e. PDF in a Word document, I
want to read inserted PDF document and save it into some other package while
the Word document is open.

Can someone tell me how to accomplish this or where will I get the required
information to implement this task?

Thanks,
Prasad
