win32com problem

[cfriedalek@gmail.com]

I'm interacting with a third party application using python and com.
However having problems and don't know what to look at next to resolve
the issue.

The app. can be driven by VBS. The following VBS code works:

Set Synergy = CreateObject("s ynergy.Synergy" )
Synergy.OpenPro ject "D:/temp/project.mpi"
Synergy.Project .OpenItemByName "test_bar_3d_6l _pc1", "Study"
Set Tet = Synergy.StudyDo c.GetFirstTet()
While Not Tet Is Nothing
Str = Tet.ConvertToSt ring() + " "
Set Tet = Synergy.StudyDo c.GetNextTet(Te t)
MsgBox Str
WEnd

This prints "TE1" "TE2" etc


The "same" code in python returns <COMObject <unknown>with each call
to the GetNextTet method.

import win32com.client
from win32com.client import Dispatch
Synergy = win32com.client .Dispatch("syne rgy.Synergy")
Synergy.OpenPro ject("D:/temp/project.mpi")
Synergy.Project .OpenItemByName ("test_bar_3d_6 l_pc1", "Study")
tet = Synergy.StudyDo c.GetFirstTet
while tet:
print str(tet)
tet = Synergy.StudyDo c.GetNextTet(te t)

Any clues on what I'm doing wrong, or how to investigate whether there
is a bug in win32com or in the third party apps com implementation.

tet = Synergy.StudyDo c.GetFirstTet() , perhaps?

Re: win32com problem

tet = Synergy.StudyDo c.GetFirstTet() , perhaps?

com_error: (-2147352573, 'Member not found.', None, None)

Sorry, should have mentioned that I tried that already. Any thoughts on
how to establish if the problem is with win32com or the 3rd party app?

Re: win32com problem

Have you tried late binding? Does late binding produce the same error?

Can you see the difference...?

Run it on the debugger step by step, and inspect all the intermediate objects.
Synergy.StudyDo c might be a function, by example, so you should add
another pair of ().
This is not obvious looking at the VB code.

(Sorry, tied up this arvo so I could respond to your suggestion
earlier.)

Here's part of a debug session.

(Pdb) type(Synergy.St udyDoc)
<type 'instance'>

(Pdb) type(Synergy.St udyDoc.GetFirst Tet)
<type 'instance'>

(Pdb) Synergy.StudyDo c.GetFirstTet
<COMObject <unknown>>

(Pdb) dir (Synergy.StudyD oc)
['_ApplyTypes_', '_FlagAsMethod' , '_LazyAddAttr_' , '_NewEnum',
'_Release_', '__A
ttrToID__', '__LazyMap__', '__call__', '__cmp__', '__doc__',
'__getattr__', '__g
etitem__', '__init__', '__int__', '__len__', '__module__',
'__nonzero__', '__rep
r__', '__setattr__', '__setitem__', '__str__', '_builtMethods_ ',
'_enum_', '_fin
d_dispatch_type _', '_get_good_obje ct_', '_get_good_sing le_object_',
'_lazydata_'
, '_make_method_' , '_mapCachedItem s_', '_oleobj_', '_olerepr_',
'_print_details _
', '_proc_', '_unicode_to_st ring_', '_username_', '_wrap_dispatch _']

(Pdb) dir (Synergy.StudyD oc.GetFirstTet)
['_ApplyTypes_', '_FlagAsMethod' , '_LazyAddAttr_' , '_NewEnum',
'_Release_', '__A
ttrToID__', '__LazyMap__', '__call__', '__cmp__', '__doc__',
'__getattr__', '__g
etitem__', '__init__', '__int__', '__len__', '__module__',
'__nonzero__', '__rep
r__', '__setattr__', '__setitem__', '__str__', '_builtMethods_ ',
'_enum_', '_fin
d_dispatch_type _', '_get_good_obje ct_', '_get_good_sing le_object_',
'_lazydata_'
, '_make_method_' , '_mapCachedItem s_', '_oleobj_', '_olerepr_',
'_print_details _
', '_proc_', '_unicode_to_st ring_', '_username_', '_wrap_dispatch _']

I'm pretty green with this kind of introspection (but willing to dig in
and learn). With the VBS code seems like GetFirstTet is a method of
StudyDoc that returns a variable which converted to string yields "TE1"
etc. But that doesn't seem to be true for python.

Is there any other way I can find out what attributes etc are available
to the GetFirstTet instance?

The type library is not supplied with the app. so if my basic
understanding is correct, I can't early bind.

Re: win32com problem - Problem Solved

Problem solved.

Turns out it was a problem of mistranslating VBS code to Python.

The PYTHON line "print str(tet)" casts tet to a string and prints. This
is what I thought the VBS line "Str = Tet.ConvertToSt ring()" was doing.
But of course "ConvertToStrin g()" is a method of a Tet instance. So in
python the correct line should have been "print tet.ConvertToSt ring".

Learning all the time.
