Automatically open a PDF in Reader and import an XML file

Hi Folks

I am trying to find a way to automate opening a PDF form in Reader and import an XML using VBA.  I have been trying with the AcroExch.PDDoc object, but am getting error 462 - the remote server machine does not exist, though I am testing with a PDF file on my local computer.  Any thoughts?  Is there a command line parameter to load an XML file automatically?

Thanks.
