VBA change pdf file properties

[decadence]

Hi, Is there a way to change the owner and computer name of a pdf, It sounds a bit dodgy but what I am trying to achieve is a set the properties so every pdf that is created so it uses a generic owner name and computer name of which will not be any users. I looked at chip pearson's .bas files but not sure where to go with that, Is there any code that can be run to change a pdf's properties. Any light on this would be helpful.
