I am trying to use this code: http://www.foxite.com/archives/print-a-pdf-file-0000080476.htm to print PDFs using ShellExecute, but even though my PDF file is valid and in the folder I'm sending to this code,

ShellExecute(0,"open", FULLPATH(This.cDefaultOutputFile),"","",1) does not evaluate to greater than 32

Any ideas? I'm willing to try different logic. I have a table with a list of PDF's ready to go.
