Can I convert a document to PDF format using VBScript

You should try the documentation for PDFCreator (its COM interface), as it states that

"From Version 0.8.1 RC9 the PDFCreator has a COM Interface included. So it is possible to control the PDFCreator using the command line of any other application.
Nearly all possiblities of the program are available using the COM Interface. The COM Interface includes Public classes, Public properties, Public methods and Public events."

I think there you should find methods to use.

And, if you prefer some other pdf-convertion tool, I'm sure they have similar interfaces.
