[IronPython] Word and MissingMemberException, 'tuple' object has no attribute 'SaveAs

[Martin Maly]

The problem is that app.Documents.Open returns multiple values (in addition to regular return value, there are others either via ref or out parameters). This is what IronPython translates into tuples. This is quite common construct in Python:

def multiple():
    return 1, "hello", 4.5

i, s, f = multiple()

Similarly, you can capture the multiple return values from Word's Open to a tuple and then inspect its elements to find out which one is the actual document. It appears from the printout below, that it is the one at index zero. Therefore, you can write:

    values = app.Documents.Open( ... );
    myDoc = values[0]

Subject: [IronPython] Word and MissingMemberException, 'tuple' object has no attribute 'SaveAs


Hi,

I am new to IronPython but have a couple of years experience with Python.
Currently I am stuck with a problem trying to open a Word document (WordML)
and saving it as .rtf back to disk

The exception I get upon call of myDoc.SaveAs is:

MissingMemberException, 'tuple' object has no attribute 'SaveAs'

when I check myDoc (obtained from Word.Documents.Open) in the CLR debugger I
see indeed that I got a tuple
but it does not look like a Python tuple and I dont know how to handle that:

-       myDoc   {(<DocumentClass object at 0x000000000000002B>,
'D:\\Projekte\\SGMLtoRtf\\dirWatch_SGMLtoRtf\\test\\HelloWorld.xml',
<Missing object at 0x000000000000002C>, True, <Missing object at
0x000000000000002C>, <Missing object at 0x000000000000002C>, <Missing object
at 0x000000000000002C>, <Missing object at 0x000000000000002C>, <Missing
object at 0x000000000000002C>, <Missing object at 0x000000000000002C>,
<Missing object at 0x000000000000002C>, <Missing object at
0x000000000000002C>, <Missing object at 0x000000000000002C>, <Missing object
at 0x000000000000002C>, <Missing object at 0x000000000000002C>, <Missing
object at 0x000000000000002C>, <Missing object at 0x000000000000002C>)}
object {IronPython.Runtime.Tuple}

so the type is IronPython.Runtime.Tuple
What is wrong with using Documents.Open from IronPython?

My script, stripped down a little bit, is:

import System.Type

import clr
clr.AddReferenceByPartialName("Microsoft.Office.Interop.Word")
import Microsoft.Office.Interop.Word as Word # ApplicationClass,
WdSaveFormat

import sys
sys.path.append(r"c:\python24\lib")
import os

inPath = r".\test\HelloWorld.xml"
inPath = os.path.abspath(inPath)
assert os.path.isfile(inPath), "not found: %s" % inPath

outPath = os.path.splitext(inPath)[0] +".rtf"

app = Word.ApplicationClass()
try:
    readOnly = True
    myDoc = app.Documents.Open(inPath, System.Type.Missing, readOnly,
*[System.Type.Missing]*13);

    myDoc.SaveAs( outPath,
        Word.WdSaveFormat.wdFormatRTF, # FileFormat
        System.Type.Missing, # LockComments
        System.Type.Missing, # Password
        False,    # AddToRecentFiles
        System.Type.Missing, # WritePassword
        System.Type.Missing, # ReadOnlyRecommended
        System.Type.Missing, # EmbedTrueTypeFonts
        System.Type.Missing, # SaveNativePictureFormat
        System.Type.Missing, # SaveFormsData
        System.Type.Missing, # SaveAsAOCELetter
        System.Type.Missing, # Encoding
        System.Type.Missing, # InsertLineBreaks
        System.Type.Missing, # AllowSubstitutions
        System.Type.Missing, # LineEnding
        System.Type.Missing, # AddBiDiMarks
    )
    myDoc.Close(
        False, # SaveChanges
        System.Type.Missing, # OriginalFormat
        System.Type.Missing, # RouteDocument
    )

finally:
    app.Quit(*[System.Type.Missing]*3)


How can I call member functions of a Word document obtained from
Documents.Open?
