[python-win32] Python Automation Question

We have decided to oset the default printer in a macro which we must run
on the excel report and hope that all will work on Monday when in
production.
I would like to find a python solution which I could refactor into the
correct place. Again, my wits with Python still have not formed.
Also... I am unable to dedicate to much time to this task for the time
being.
Thanks for the suggestions. I will try and think outside the box using
them as guidance.
Greg

Hi,
I'm using Python 2.5 and pywin32 build 212 to produce an application
with services.
The services load C++ DLLs, for example snap.pyd, to do some of the
work.
All working fine until a customer installed pywin32 build 214 then some
of the services don't load, because some of the DLLs load others do not
:(
The error I get in the Windows Event Viewer looks like this
Python could not import the service's module Traceback (most recent call
last):
...
import snap
ImportError: DLL load failed: Invalid access to memory location. %2: %3
The DLLs load fine in PythonWin and if the .py file which includes the
import is run from the command line.
The .py file only fails if run by PythonService.exe.
If there is someone out there who can say "yes that's because you have
not done .... "
that would be wonderful.
Otherwise is there a list of the changes from build 212 which could
break existing applications so that I can work out what I've got to
change ?
I hope this has all made some sense
Thanks Tim.

Hi, "le dahut". (Sorry; how would you prefer to be addressed?)
What would be really useful is one or two paragraphs outlining the
problem you're solving with this solution :) I've more-or-less followed
your posts here over the past year, and your code's quite readable so I
can get an idea, but perhaps something along the lines
of:
The requirement: xxxx
The problems: xxx
The solution: xxx
would be helpful. No need for too much text; just an outline on which to
hang your different pieces of code.
Thanks
TJG

The number of items is limited only by available memory. I know of apps
that have used more than 100,000 items. Why do you believe there is a
9,999 line limit?

You can do it when you add the column using LVM_INSERTCOLUMN, or you can
do it afterwards by sending LVM_SETCOLUMN. You set the "fmt" member of
the LVCOLUMN structure to LVCFMT_RIGHT or LVCFMT_CENTER. Be sure to set
LVC_FMT in the "mask" member to indicate that you're changing the
format. If you use LVM_SETCOLUMN, you should probably do an
LVM_GETCOLUMN first, then modify the current settings.
The leftmost column is ALWAYS left-justified. This cannot be changed.
This seems like the hard way to write an application. Have you
considered using a GUI framework like Tkinter or Qt or (my favorite)
wxPython?

Hi, Tim!
Thanks for your answer.
>> - The size is limited to 9999 lines ; how define more?
> The number of items is limited only by available memory
You are right. I tried with 300 000 lines, without problem.
I do not know I had a 9999 limit on my first tests... Sorry for
trouble.
Little info (for other readers):
This code give more speed:
win32gui.PostMessage(self.hwnd, win32con.WM_SETREDRAW,0,0)
...(preparation of data in show)...
win32gui.PostMessage(self.hwnd, win32con.WM_SETREDRAW,1,0)
win32gui.UpdateWindow(self.hwnd)

OK, it's run. Without LVM_GETCOLUMN first. But with
win32gui.UpdateWindow
after.
Thank you very well & again :)))
> The leftmost column is ALWAYS left-justified. This cannot be changed.
In my W7, I can align the column 0 (leftmost) without problem. Perhaps
because I insert it in last operation?

I tried TK: limited.
I tried wx: I let down, because several conflict's versions, and it is
very
complicated.
Actually, I use Autoit like GUI, and Python's functions linked to
UIobject
and events (via COM) ; run OK, but not pythonic.
Also I use IE like GUI, with PLUIE
(http://ponx.org/ponx/guiescreens.htm) ;
but it is not very fast.
I think than a pure pywin32 is a good way to explore.
Have a nice day.
