Word Documents

I have to get the last updated date of many, many word documents. These documents are decoded from attachments in email (not read from a disk file). I am using CDO and ADO to read in *.eml files, using 'getstream' on the IBodyParts. This allows be to get a stream (decoded) of the word document. I must get the date here, because if I write it to disk, then use the Word objects to read in the document, the dates reflect the date and time of this last save. Any help would be appreciated.
