You don't need to start a new thread to ask. Just do a
reply to the answers you got and ask what you didn't
understand.

Anyway, answering to your question, you could start by
modifying this script:

http://www.zope.org/Members/mjablonski/howtoPDF

It produces a PDF on the fly, but you could do a doc to
html document. You just have to do some modifications:

* Add a parameter for the url where your word document is.

* Instead of calling htmldoc, install wvware (see my
   previous reply to your message) and call wvHtml.

* This method returns a PDF, but doesn't store it on the
   ZopeDB. So, if you want to store it on the ZopeDB, then
   you will have to do the following:

from OFS.Image import manage_addFile

container=self.restrictedTraverse(FolderURL,None)
manage_addFile(container,id,title=title,file=data)

There are may be more modifications, so, it won't work
at first. If you don't get it working, then post your code
and we will try to help you.

Josef
