disable "save as" dialog box

Hi All,

I have a pc running as part of a public installation and as such I
have some special needs. One of them is the ability to save documents
to a predefined directory non-interactively. So what I would like to
do is to set the default save to location and then disable the "Save
As" dialog box. I don't even want to see it come up when I save. Is
this possible? Let's assume that all the files being saved already
have filenames.

Thanks,
