To answer your question directly first: you might be able to automate your process using a script written in vbscript or jscript under the Windows Scripting Host, by creating scripts that start the relevant applications and contol them via SendKeys. See some examples here, here, and many other places (search for "vbscript sendkeys" or similar in <insert search engine name here>
). Unfortunately the comments on the Microsoft documentation for sendkeys (found here) suggest that this will not work under Vista.
What is your particular need to have the documents in SWF format? The answer to that might net you some suggestions of other ways to achieve your goal if it turns out the software you are currently looking for does not exist.
If you are wanting to publish documents so they can be read by web users who may not have either the relevant word processor or other document reader (such as Acrobat Reader for which you could convert the documents to PDF instead), then you might be able to use an embedded instance of Google's document viewer. This works without any extra client applications or plugins (you just need Javascript turned on in your browser) though you will still need to convert the documents to PDF format, as it doesn't support any word processor formats directly, and make the PDF available online somewhere. See this page for an example.
One further point that may help get relevant answers: can you describe the content of the documents in question? Are they all text, a few graphics, or very graphical? A few pages each or hundreds? What is the initial size of the documents (before conversion) and the resulting sizes that are too large?
Why does it need to be a swf? A pdf won't due? – MDMarra – 2009-09-28T11:53:19.837
