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

[Michael S]

I am trying to force late binding, since obviously early binding does not discover the methods that I am trying to call.
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)
