Hello all,

I am making pivot tables using pywin32 and was wondering how I could add borders to the pivot tables through python.
Would greatly appreciate any help. Thank you in advance.

Message-ID: <CA+67nohMAywzdtAxSjUBJjCWfjyOUZ7a_9=n2NwY4mjAxMDmcw@mail.gmail.com>

Earlier today I downloaded the pywin package to work with Microsoft
Outlook. On the below code I received Error -2147221005. I'm uncertain if
this has to do with an installation of the library not working
properly/version issues. I use a 32 bit version of Python 3.7.

*Python Code:*

import win32com.client as client
outlook = client.Dispatch("Outlook Application")
message = outlook.CreateItem(0)
message.Display()

*Full Error Message:*
Traceback (most recent call last):

line 81, in _GetGoodDispatch
    IDispatch = pythoncom.connect(IDispatch)
pywintypes.com_error: (-2147221005, 'Invalid class string', None, None)

During handling of the above exception, another exception occurred:

Seems like you have the class string invalid?

?Outlook Application? should read ?Outlook.Application?

Note the period.  ?

And then of course, you need Outlook installed, and the correct 32-bit or 64-bit version of Outlook for your python version.

HTH and Enjoy

 DispatchWithEvents()
Message-ID: <CAEv6-3uB1g9AOE_UMA9yjNeCmGQmoCNMb8yE-1+P4FgPcPMwWQ@mail.gmail.com>

Hi everyone,


I'm trying to make a cross-platform Python interface for a third-party API
(Druide Antidote). The D-Bus part is done and working (
https://gitlab.com/-/snippets/2151173), it consist of a server adapter
(AdaptateurAntidote), which relay the events to an handler class
(ImplementationAntidote).


I want to do the same with the COM interface. However, I could not get
DispatchWithEvents() to work, as it fails on "ti =
disp._oleobj_.GetTypeInfo()";


C:\Users\user>"C:\Users\user\Desktop\AntidoteCOM.py - Shortcut.lnk"

I noticed that when running localserve.serve() in a separate console, the
server returns as DispatchWithEvents() is called. No errors are thrown on
the server side, but I assume there is something wrong or missing in the
class definition of AdaptateurAntidote. I tried changing its policy to
dynamic, but that did not help.


*If someone could provide a minimal example of a custom server working
along with DispatchWithEvents(), that would be very helpful. *All the
examples I could find use third-party servers, such as those provided by
Microsoft.

DispatchWithEvents creates a COM object, then gets the typeinfo needed 
to implement the interfaces defined for events - but this COM object is 
failing to provide that type info at runtime. It might still have a .tlb 
available though, and if it does, you can run `makepy.py` once and the 
snippet should work. The typelib can also live in a .dll, but I've never 
heard of Antidote so have no better suggestions.

Cheers,

Mark

Hi,


There is no typelib file unfortunately. The interface needs to communicate
with Antidote's API by creating a COM server which exposes the methods
defined in the AdapteurAntidote class.


The problem is that the widget queried (a QTextEdit) is instantiated in
another class (MainWindow), and I cannot attribute a "parent" to the
dispatched COM object (self.server), as it raises either an AttributeError
or a TypeError, depending on its declaration in __public_attrs__.


>From the documentation, I thought I needed to use DispatchWithEvents to
handle the events in a separate "sink" class (ImplementationAntidote) that
would behave more like a generic python object. Is there any other way to
achieve this? It is quite a trivial feature so I assume it is possible to
do so?


Best,

Will

DispatchWithEvents helps with the most common pattern used for COM 
events, particularly with MS products - in this model, the interfaces 
are described in a typelib. However, products are free to define events 
in whatever makes sense for them - eg, the object could take a plain 
IDispatch and try and dynamically query and deliver events to the 
methods here. If that's what the app in question does, then yeah, you 
don't need DispatchWithEvents and can do something simpler. However, 
I've no idea how that product works nor what it does, so can't really 
answer the question.

I suspect you aren't the first person to run into this though and I 
assume the object is usable in a number of languages which support COM, 
so you might be better off asking in a forum specific to the product.

Cheers,

Mark

Hello,

When I run pip install pywin32 in WSL2:Ubuntu using Python 3.8.8 I get the following error log:

Any ideas?

Kind regards.

WSL is a linux environment - pywin32 simply doesn't work there. You can 
install it via a Windows command-prompt, or in WSL stick to the versions 
of Python that work for Ubuntu but without pywin32.

In short, Antidote binary is launched, then its IApiOle interface takes the
Dispatch object of the custom server I made and uses it to communicate back
and forth.

Using the Dispatch() method, the interface I made is working as expected,
which means that the methods exposed in AdapteurAntidote are then being
queried (updated example below). I did not try delivering back the resuts
but I assume it should work.


What I could not achieve is to get the server adapter class
(AdapteurAntidote) to work with objects which are created at runtime,
namely instances of other classes. I cannot set another runtime object as
an attribute of the adapter class, nor pass it on instantiation. Thus, the
adapter is quite useless in this case. Is it even possible using pywin32?
If so, how?


Looking back at Antiote's C++ example, there is an idl file available from
them. Is it necessary though? I would rather do everything dynamically,
such as setting the GUID, just like I did for the DBus interface.

You can get and set properties which are COM objects in the same way you 
can get and set any other properties.

A .idl file isn't much good to pywin32 - it wants a compiled version 
(aka a typelib.) I'd be quite surprised if their DLL had a .idl file and 
not a compiled version of it.

In general, early-binding via a typelib should not be necessary - 
however, pywin32 does far less guessing about things when a typelib 
exists. It will be clearer what properties exist, what type they are and 
how to call them. It may well be that it is the difference between 
things working and not working. - so in this case it may well be 
necessary in practice.

Hi,


Thank you for the follow up. Perhaps I did not express my need clearly
enough, so I made this minimal example;

The Ping() method would usually be called from the third-party app, but
here it is done locally for the sake of demonstration.

That exception is very odd and I should look into it - but the problem 
here is that you are trying to set an attribute on a COM object which is 
a Python instance, which doesn't really make sense. What you want is to 
set it to a COM object - which `self` is not. So something like:


class Main:
     _public_methods_ = ["pong"]
     def __init__(self):
         self.server = win32com.client.Dispatch("Minimal.Example")
         self.server.parent = win32com.server.util.wrap(self)
         self.server.Ping()

     def pong(self):
         return "pong"

works. Sadly another paper-cut here is that the server just sees this as 
a plain IDispatch object rather than a `Dispatch` wrapper - so `Ping` 
needs to look something like:

     def Ping(self):
         parent_as_object = win32com.client.Dispatch(self.parent)
         print(parent_as_object.pong())

I guess you could, say, change `parent` into `set_parent()`, or 
intercept via __setattr__() and do the wrapping just once.

HTH,

Mark
