[python-win32] AVDoc and PDDoc/How to force late binding

[Michael S]

You are right. I made a mistake, it forces early binding.
However neither late nor early can discover the AcroExch.AVdoc method I need and VB does it with no problem.

By the way I can force early or late binding on the Excel.Application, but for some reason not on Acrobat classes.

EnsureModule forces *early* binding

I ran the makepy -i from within PythonWin, to get those two lines I need to paste in into my script.
from win32com.client import gencache
gencache.EnsureModule .......

However when I run the script, I get an com_error saying that  dynamic.py couldn't find a certain method?
I thought that EnsureModule should force late binding.

Thanks a lot Justin. I tried running your code, for some reason it just hangs. I wonder why.

was experimenting with Acrobat months ago 

import win32com.client.dynamic

NOSAVE = -1
PDSAVEFULL = 1

class Acrobat2pdfError(RuntimeError): pass

def Acrobat2pdf(src, dst):
   avdoc = win32com.client.dynamic.Dispatch("AcroExch.AVDoc ")

   if not avdoc.Open(src, "doc2pdf"):
       raise Acrobat2pdfError("unable to open %s" % src)

   pddoc = avdoc.GetPDDoc()

   if not pddoc.Save(PDSAVEFULL, dst):
       raise Acrobat2pdfError("unable to save %s" % dst) 

   if not pddoc.Close():
       raise Acrobat2pdfError("unable to close %s" % dst)

   del pddoc

   if not avdoc.Close(NOSAVE):
       raise Acrobat2pdfError("unable to close %s" % src) 

   del avdoc

if __name__ == '__main__':
   import os
   src = r"C:\test\file1.doc"
   dst = r"C:\test\file2.pdf"
   Acrobat2pdf(src, dst)
   assert os.path.isfile(dst)
