I'll have to look into this further to see if
Adobe's PDF Reference documentation includes any information about how
to create a PDF object that gives a field (tagged?) that capability.
Some possibilities:
Forms Data Format (FDF from the PDF Reference version 1.7, p. 710):
"FDF is used when submitting form data to a server, receiving the
response, and incorporating it into the interactive form. It can also
be used to export form data to stand-alone files that can be stored,
transmitted electronically, and imported back into the corresponding PDF
interactive form."
The FDF seems to allow JavaScript also.
Adobe XML Forms Architecture (XFA from the PDF Reference version 1.7, p.
722):
"PDF 1.5 introduces support for interactive forms based on the Adobe XML
Forms Architecture (XFA). The XFA entry in the interactive forms
dictionary (see Table 8.67) specifies an XFA resource, which is an XML
stream that contains the form information. The format of an XFA resource
is described in the XML Data Package (XDP) Specification (see the
Bibliography)."
The XML Forms Architecture (XFA) Specification is 1345 pages! I had no
idea how much capability Adobe put into XFA. It's going to take me a
while to determine what can and should be done from Access. Maybe
Acrobat Professional is your best bet for quickly getting interactive
PDF Forms up and running. One plus for Access is that any PDF created
from Access is the initial one as specified for FDF and therefore Access
does not have to deal with the logic required to implement incremental
changes to PDF objects or files. Tagged PDF might even allow a PDF Form
to display and work on something like an iPhone.
