Subject: [python-win32] Using COM Event. A problem
Message-ID: <CADMj6LB-nAK0CyFuZcNjEaAkN2xSfsDUgQYBL+hpD0JYycc2NA@mail.gmail.com>

Dear All,

I am trying to create a call back for som events generated by a COM server
that I connect.
Looking at some posts apparently related to the same topic, I wrote this
sample code to test:

import win32com.client as com
from win32com.client import gencache

class Eventi:
    def Device_Notify(self,EventCode):
       if EventCode==0:
         print "begin"
       elif EventCode==1:
         print "end"

mod = gencache.EnsureModule('{B4955EC7-F7F2-11D2-AA9C-444553540000}', 0, 1,
0)
ob = mod.Application()
objCybio = com.DispatchWithEvents(ob, Eventi)

When I run this code, it starts the connection, but soon after it is
stopped with the following error:

Traceback (most recent call last):
  File "evento.py", line 13, in <module>
    objCybio = com.DispatchWithEvents(ob, Eventi)
  File "D:\Python27\lib\site-packages\win32com\client\__init__.py", line
256, in
 DispatchWithEvents
    raise TypeError("This COM object can not automate the makepy process -
please run makepy manually for this object")
TypeError: This COM object can not automate the makepy process - please run
makepy manually for this object

I did run the makepy, but still the same error.
Do you have any suggestion of what it could be wrong?

Thanks a lot for your help

Nicola

Do you get the same result if you replace those three lines with this?

??? objCybio = win32con.client.DispatchWithEvents("Maxim.Application",
Eventi)

Subject: [python-win32] Writing an COM server and client with PyWin32
Message-ID: <CAE-5t2sPqn2eg+o_m=UqZJRFmNfJUV=j2znKayc=LwnTdoWbdg@mail.gmail.com>

Dear mailing-list members,

first I'd like to introduce myself. I'm Thomas Pietrowski and I'm working
on a plugin, which shall enable Windows Automation for Cura.
Cura is a slicing application for 3D-printers written in Python and I would
like to control this application over COM.

The last weeks I worked hard on getting something working and managed to do
function calls and get values of some attributes.
However, something I still don't manage to do is receiving signals.

While slicing there is the progress sent within Cura as a Qt signal. This
is one of the Qt signals, which I would turn into a COM event.
So whenever the progress changes, the widget in the GUI will get updated,
as well as the event will be sent over COM.

However, this is what I have in mind. What I still can't manage to get
working is executing a "DoEvent()" function, which emits an signal and
receiving the "OnEvent()" in my handler.
Whenever I want to DispatchWithEvents() or do a WithEvents() on a running
client session, I always get an error that the client can't manage to
automise something and I shall use makepy.
After using makepy I still get the same issue. So I guess I made something
wrong while writing my IDL and/or COM server. Therefore my client is not
able to get all the info it needs.

All source are available on GitHub:
https://github.com/thopiekar/CuraInterfacePlugin/tree/master-sending-and-receiving-signals
(here: "master-sending-and-receiving-signals" branch)

Do you see any mistakes I made?
Alternatively, do you have a working server/client example with working
events? This would probably give me an kickstart :)

With kind regards
- Thomas Karl Pietrowski

Subject: [python-win32] playing with scintillacon
Message-ID: <ad6b9cb6-2eae-305c-b55c-ef51e06db164@totalrewind.com>

Hey all,

I recently noticed that pythonwin comes with a scintilla wrapper. Seems 
USEFUL!? so I decided to (scientifically) try poking it with a stick to 
see what it does.
(https://github.com/mhammond/pywin32/tree/7da19cd2ca3fac06638d9af690b8b6f5fcc65e8b/Pythonwin/pywin/scintilla)

I didn't get too far, for when I do:
 ??? from scintilla import scintillacon
I get:
 ??? ImportError: DLL load failed: %1 is not a valid Win32 application.

Presumably this means there's a dll it can't find?? Unfortunately the %1 
is not replaced with what it's looking for.? (If there's not a bug out 
on this somewhere, there probably should be.) That's not the point 
though.? Point is: what are we looking for?

Thanks,
-Kurt

"... not a valid Win32 application" sounds like a 32/64-bit issue to me. 
The 32/64-bit version of python you're running: does it match the DLLs?

Ok, I found scintilla.dll in the directory above scintillacon.py, but it 
came with pywin32, so it *should* be the correct one.
DLL inspector says it's a 64-bit, which is correct for my os.

I copy that dll, and indeed, all binaries in that directory (just to be 
sure) into my program directory and it still does not work!

Yet, the program Pythonwin.exe in that directory works fine and does its 
syntax highlighting with scintilla.dll.

I have no idea what could be wrong.? Oh!? To know what that little %1 means!

Try importing win32api in the same context. If that fails, check PATH
for pywintypesXY.dll:

    where pywintypes*.dll

System error message include inserts such as %1 for when errors and
exceptions are shown by the system itself. All Python has in this case
is the error code, ERROR_BAD_EXE_FORMAT. So when it calls
FormatMessage, it uses the flag FORMAT_MESSAGE_IGNORE_INSERTS, as it
should.

I already had "import win32api".

As for pywintypes27.dll, it is one of four files automatically placed in 
c:\windows\system32 by the installer, which is a pretty sure thing as 
far as being able to find it.? I was getting desperate so I even copied 
it over, AND all the binaries from the 
C:\Python27\Lib\site-packages\pythonwin directory for good measure.? I 
checked the security privileges on all of them and verified that they 
were 64-bit using a PE explorer (ProcessHacker2).

There must be something else I'm missing.

NOTE:
I am basing my code on the example 
C:\Python27\Lib\site-packages\win32comext\shell\demos\servers\shell_view.py 
ScintillaShellView class.? Which is supposed to implement a windows 
explorer preview with scintilla highlighting.

Anyway, when I try and run that full sample, I get a folder created that 
I cannot open.? (Like it's registered correctly, but the code behind it 
is kaput.) ? I use NirSoft's shell extension viewer 
(http://www.nirsoft.net/utils/shexview.html), and it tells me it "cannot 
find c:\Windows\system32\pythoncom27.dll". Bafflingly, it IS THERE!? 
And, since it is another of the same set of dll's created by the 
installer, I'm wondering if this might be a clue?? Could there be a 
problem with the way the dll's are compiled and/or installed??
