Hidden data in word/excel document

[Martin]

Hi,
I must hide some data in word document. The data is related to digital
signature and document encipherment and of course all changes should be
invisible for viewers.
I tried solving problem by using IStorage interface and writing my own
stream to file, everything seems to be ok until user presses save button.
Even there were no chages word flushes all my data (stream).
Same solution works perfect with excel.
Could you suggest any solution ?

regards,
Martin

Hi Martin,

It's been a few days, and I haven't seen a response. I have no idea if what
you want to do is possible with Word (or the version of Word you're trying
to use). If I wanted to store information in a Word document that the user
can't see (without VBA), then I'd put it in document Variables (look up
Variables in the Word object model).
