Look for the *.cfg files in the pythonwin directory.
Thanks.
maybe some of the following stuff is useful for somebody, or for
future PythonWin default:
In attachment a patch for pywin/default.cfg, which does context
(word) sensitive help from editor into Python Help and PythonWin Help
F1 = HelpPy
Ctrl+F1 = HelpPyWin
..
and allows for faster edit-run cycle: running/interacting with
(auto-unindented) selected code lines from editor
Ctrl+K= Interact_SelectedLines
Ctrl+E= ExecGlobal_SelectedLines
( the little patch of scintilla/config.py enables correct line
numbers for traceback and debugging of code in default.cfg )
-
Also CtrlEnter.patch (-> framework/interact.py), which enables
ad-hoc debugging from interactive pane (Ctrl-Enter) into an
interactive statement (without long-winded F5 running into
breakpoints etc). I did not put the code into default.cfg, because
a lot of pre-processing code is shared with normal interactive
statement execution.

The meaning of time.time isn't really relevant to this.
GetFileAttributesExW returns values directly from the file system, and
NTFS happens to store its timestamps in UTC. os.path.getmtime adjusts
to local time.
FAT file systems record timestamps in local time, which causes the
reported times to change during summer time.

any shift (NTFS)

it doesn't make sense. Seems PyTime internally forces to "wall

Guess int-time values should never have local/summer on it? -

time.time() / getmtime() is absolute / UTC. and win32file says:
compatible with time.time. a int value doesn't make sense as
localtime?
It even picks up daylight saving, so the int file times would
change in winter

The meaning of time.time isn't really relevant to this.
GetFileAttributesExW returns values directly from the file system, and
NTFS happens to store its timestamps in UTC. os.path.getmtime adjusts
to local time.
FAT file systems record timestamps in local time, which causes the
reported times to change during summer time.
That's part of the explanation. That explains why the symptom doesn't
show up on FAT systems, but not what the symptom is really about.
When converting UCT to local time, there are two reasonable algorithms.
For most people, one of them makes sense, so the other sounds like a
bug. But people are very split as to which one is the "right" one.
If you're converting the current time to local, it seems logical that
you'd add the timezone offset, adjust for daylight-savings if it's
"summer," and be done. And if two people do it in two different time
zones they'd get different answers for "now." Likewise if one of them
is in a state or country that doesn't honor dst, they'd be off by an hour.
But what's the "right" answer for a file timestamp, or for any other
historical date/time? If the file (on a laptop, NTFS, say) was created
in California, and being examined in Maine a few months later, you'd
expect that the Maine time zone would be used. After all, the file
system doesn't store the fact that the laptop happened to be in
California when the file was created.
But what about the dst (daylight-savings) conversion? That's the
problem. One philosophy says it should be the dst state that was in
effect at the time the file was created, while the other applies the dst
state at the time of the conversion. If I recall correctly, getmtime()
uses the first approach, while GetFileAttributesExW() (and DIR) use the
second.
The net effect of this is that if last winter you created a file at 3pm,
and you have NOT changed time zones, then when you look at that file now
with GetFileAttributesExW() it'll tell you it was created at 4pm.
Notice that remote file access can complicate this, as can programs that
store the time stamp in local time. I ran into this problem many years
ago when saving digests of files to later check for corruption. I
suspect you'd have the same problem when restoring a file from CD, if
daylight savings time has changed. It's time stamp would be recreated
wrong. Similarly zip files or other archives. I've even run into
something similar on a FAT drive, when I ran across a file that was
created during the "impossible" time each spring between 2 and 3am on
dst-day.
Well I think, the integer time does/should generally aim at a
absolute value as good as possible - time.time() and
os.path.getmtime() seem to do. Nothing with local/dst. No problem,
no loss of information (e.g. on NTFS). Even the term "UTC" doesn't
make sense so far ( except for defining *verbally* the absolute
start point 1.1.1970 XX:XX UTC )
http://msdn.microsoft.com/en-us/library/ms724290(VS.85).aspx
"A file time is a 64-bit value that represents the number of
100-nanosecond intervals that have elapsed since 12:00 A.M.
January 1, 1601 Coordinated Universal Time (UTC). The system
records file times when applications create, access, and write to
files."
-> just a fix offset to Python time.time()
Guess this is wrong in win32file; or win32file looses info by
early conversion to digits.
"local/timezone/dst.." just makes sense for display values: "wall
clock digits".
When info is missing in time stamps / digits stored, like with FAT
time stamps, then only the question arises, which assumptions to
make on int-conversion - UTC/local time zone, or even DST. In that
case its necessary to know (by an additional flag/attribute the
assumption)

It seems, rude C-level leaks went into win32ui during 212 -> 214 - maybe
because of the rework for py3k.
Or is it all about one leak?
214 ui is hardly usable anywhere with various python versions - most practical use cases in and around win32ui become questionable. Yet there was no update for long
time. I wonder that there are not many pywin32 bug reports in that direction.
I only found :
bug #2846720 (similar to C) )
and #2908939 perhaps. (->comments by M. Hammond, but no solution found)

Actually, the problem is that it *won't* allow a view to be created without a document, even though it should. If I remember correctly, at the MFC level, the constructor for the view object I'm using doesn't even take a Document as an argument -- you set it later if you want one. Win32ui goes out of its way to accept one at construction time. This wouldn't be such a serious problem, except that win32ui doesn't seem to provide any way of creating a Document without a resource -- hence the above kludge. You instantiate the MFC view object without a document, but in order to actually create a window and do anything useful with it, it needs a valid document. For some reason, the win32ui framework chooses to accept a document when the view is initially created instead of when its window is created. (That's where MFC accepts the associated document object.) I have yet to be able to determine where the dummy document is actually coming from in build 212. When I try to run it in a debug build, so many asserts are triggered that it would take forever to step thru it. The PyGUI framework can probably create a valid MFC document to use as a dummy with a little work. Something like: dt=win32ui.CreateDocTemplate(win32ui.IDR_PYTHONTYPE) win_dummy_doc=dt.DoCreateDoc() That may work if you run the program using the pythonwin executable, which contains the referenced resource. But I want pygui programs to be runnable using the standard Python interpreter, which means I can't rely on resources at all. The resource is actually in win32ui.pyd, rather than in Pythonwin itself. I've just verified that this method works from plain python.exe. The scrollable view test runs with this change. I should have written yesterday as I already found/worked on the doctemp problem yesterday, just I didn't completely solve (or better "workaround"), so I shifted .. (py2.6.5 / pywin32-214) A) in ScrollableViews.py globals: ##win_dummy_doc = ui.CreateRichEditView().GetDocument() doctemp = ui.CreateDocTemplate(ui.IDR_PYTHONTYPE) win_dummy_doc = doctemp.DoCreateDoc() #print "ScrollableViews: Created dummy doc" This lets start the blobedit.py / my test app. but at the exit hard crash. TestScrollableViews.py / 12-scroll.py crashes hard even at start (runtime to terminate in unusual...) B) in ScrollableViews.py globals: ##win_dummy_doc = ui.CreateRichEditView().GetDocument() #print "ScrollableViews: Created dummy doc" doctemp = ui.CreateDocTemplate(ui.IDR_PYTHONTYPE) import pywin.mfc.object doctemp = pywin.mfc.object.CmdTarget(doctemp) # otherwise we crash at exit win_dummy_doc = doctemp.DoCreateDoc() blobedit.py & 12-scroll.py now start, work and exit correct from commandline. (well the 12-scroll.py displays/user-interacts mostly buggy but thats not the problem here) However when I make multiple starts / close of the app-window in IDE/one process, or when in an app the total number of ScrollView's counts down to zero and then up again, then still a hard crash (somehow the doc is too smart and gets corrupt at zero count) C) the attached .patch : blobedit.py & 12-scroll.py now start, work and exit, and multi-boot, views count to zero and up again .. correct from commandline, python.exe & pythonw.exe & frozone with py2exe.

Maybe for such and similar reasons many apps crash at exit with 214. The (damn) Document/Template stuff in win32ui somehow seems to have become more instable in 214 (213?). danging pointers or so.

[python-win32] WinSxS, manifests and binary distribution ?
Hello, I want to see clearly which MFC DLLs (and VCR DLLs) pythonwin.exe or python(w).exe +win32ui.dll are actually using in Python2.6 or 2.7. And how to manage the actuall bindings/dependencies. And how to put together binary distribution files. I want to find a way to first move away the MFC DLLs, to have a situation here like on a computer without Python installed. And then put (& test) precisely the required DLLs/manifests next to a myapp.exe (win32ui based), so that I find which and how how files can be distributed.

[python-win32] manifest "Microsoft.Windows.Common-Controls" version="6.0.0.0" => strange problem with pywin32 build 216 ?
In C:\Python23 and C:\Python26 installations there are python(s).exe.manifest files which contain '"Microsoft.Windows.Common-Controls" version="6.0.0.0"' (see attached/below) With pywin32 build 216 (was not in 212; and 214 I guess) win32ui apps, which are started by these python(w).exe's , a strange auto-magical button pressing is going on, immediately after application start. almost any button is pressed when the mouse moves.. By chance its possible to stop the show in the Task Manager. It seems (seen by a debug output), that notification messages (BN_.. (Which could be routed via HookNotify?)) or so do trigger the normal HookCommand'ed handler. When that Common-Controls section (or the whole .manifest) is removed, the apps work normal in build 216. What could be the reason? What does this Common-Control section actually do?

[python-win32] SIGSEGV crash at the end of apps using win32uiole / OCX
This is about a ugly old bug which I dislike for long, which I can
only suppress by a os._exit() near Python end. Now I found some
more info. Perhaps somebody sees what it is about?
When a GUI app has ever used a win32uiole OCX like shown in the
attached minimal example (pythonwin\pywin\Demos\ocx\webbrowser.py,
just changed to use a standalone frame window), then at the very
end of the app after all windows have been destroyed and Pythons
sort of main() with destruction of all Python objects is reached,
there is a SIGSEGV like shown below in
python26!PyInterpreterState_Clear ().
Reproduced with various Python 2 versions.
Notes:
* Obviously extra threads are created by the browser OCX if at
least one .Navigate() occurred.
* if .Navigate() is commented out, and just the Window/OCX
creations/destructions are done the problem is not. (But then gdb
doesn't show creation of extra threads. Thus the problem seems to
have to do with extra threads.)
* "app.Run()" is commented out for a mere standalone run, to
reproduce the bug easily. Thus the windows are drawn down right
after creation. If not, then at exit, this (simple) app somehow
doesn't terminate but seems to wait eternally because of extra IE4
threads (?). When run with gdb as shown, the hang/eternal wait yet
is not and the SIGSEGV occurs after .Run() too (!?)
* the problem is not, when the example is run in Pythonwin.exe at
the end of Pythonwin.exe. The problem is not when such script is
run with py2exe v0.5.2 stub. (maybe that does rather quickly
something like os._exit() at the end). But the problem occurs with
current py2exe 0.6.9 stub, and with all normal python(w).exe's -
direct start or via interactive sessions.
When Pythonwin is run via python(w).exe and "import
pywin.framework.startup app.Run()", and when then the
webbcrash.py is executed, then after exit of Pythonwin the crash
is there too. Thus Pythonwin.exe unlike python(w).exe seems to do
just a sloppy cleanup (like py2exe0.5.2) and thus avoid the problem.
* when os._exit() is done at the end of the script, the problem is
not existing: the ugly "solution" ;-)
sys.exit() doesn't "solve" - probably because it doesn't prevent
against destruction of all Python objects, threads ...
* pywin32 build 216 (but same with 214)
* BTW: if the original pythonwin\pywin\Demos\ocx\webbrowser.py
(using a MDIClient) is run standalone through python(w).exe, there
is also a ugly SIGSEGV or even worse C-level crash - now at start.
It should only raise a Python exception due to the non-working MDI
setup I guess.

Re: [python-win32] Python Service error 1053: the service did notrespond to the start or control request in a timely fashion
From: "Richard Zinn"
Hi, I've implemented the MyService.py example from the py2exe samples
directory using Python2.6, on my Windows XP SP2, and I get the error
1052...did not respond in a timely fashion immediately when I run the
MyService.py, or the MyService.exe, or if I install it as a service using
an
NSIS installer script I wrote, and start it using the windows service
manager.
Any ideas? Here is the code reduced to just the essentials:
import win32serviceutil
import win32service
import win32event
import win32evtlogutil
class MyService(win32serviceutil.ServiceFramework):
_svc_name_ = "MyService"
_svc_display_name_ = "My Service"
_svc_deps_ = ["EventLog"]
def __init__(self, args):
win32serviceutil.ServiceFramework.__init__(self, args)
self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)
def SvcStop(self):
self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
win32event.SetEvent(self.hWaitStop)
def SvcDoRun(self):
import servicemanager
log("running")
win32event.WaitForSingleObject(self.hWaitStop, win32event.INFINITE)
log("stopped")
if __name__ == '__main__':
win32serviceutil.HandleCommandLine(MyService)
I've seen other posters with similar problems, but with theirs it doesn't
work in the .exe, but in my case it doesn't work when I run the .py
either.
The traceback in python says:
python MyService.py
Collecting Python Trace Output...
Traceback (most recent call last):

rt or control request in a timely fashion.')
Thanks in advance,
Richard
If SvcDoRun is run in it's own thread, then I suspect the import residing
inside that function. If I remember correctly, Python's import mechanism
causes the thread where the import takes place to deadlock, so you should
always perform an import inside your main thread. Try importing
servicemanager from the top of your script, instead of inside of SvcDoRun.
Then your example should start throwing exceptions because it can't find
'log.' :-)

[python-win32] Python Service Won't Start, But Does Debug
I'm new to using the win32 module and I've written a little service in python for myself. It runs fine and without errors when I use debug: >python myService.py debug Debugging service myService - press Ctrl+C to stop. This works and prints to a log file I set up just fine, so I know it's working properly However when I try using the start command on the same service It says it's started, but hasn't: >python myService.py start Starting service myService Then after any amount of time: >python myService.py stop Stopping service myService Error stopping service: The service has not been started. (1062) If I use a wait command: >python myService.py --wait=30 start Starting service myService Error starting service: The service did not respond to the start or control request in a timely fashion. I'm using python 2.5 and the win32module. My main class is a subclass of win32serviceutil.ServiceFramework with all the appropriate function overridden (__init__, SvcStop, SvcDoRun) the init function calls the init function of the ServiceFramework directly (not using super). When debugging it will continually run it's main loop and does everything in it I would expect, but seems to not to want to run when using start. Obviously no exceptions are thrown when I run it in debug mode. Any suggestions, or should I be posting more info? ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

[python-win32] Python script jumps back to 'main' in long running win32 event
Hi,
I'm hoping that someone can help with this... I've seen some old posts which
I think may refer to this same issue but I'm having difficulty understanding
how to come up with a solution, and particularly where any
"PumpWaitingMessages" should be located and/or/how/whether
pythoncom.CoInitializeEx(pythoncom.COINIT_MULTITHREADED) should be used.
The code processes data for 25/30 messages received back from the com object
but then seems to jump back to the 'if __name__ == '__main__' and passes
that same parameter (originally passed from the command line) and runs all
over again...
The process is intended to:
1. pass a parameter from the command line
2. open a [pickle] file to store the data
3. call a COM object with Dispatch events (to an EventHandler)
4. for each block of data received back into the EventHandler, drop it into
the pickle
5. close the pickle file
I'd be immensely grateful for any assistance you can give.
Rob
Essentially the skeleton code I have (and I hope it's intelligible) is as
follows:
if __name__ == '__main__':
arg = sys.argv[1:]
proc(arg[0])
def proc(arg):
fh = file("thispickle.pkl", 'wb')
x = Async(arg) # see below
fh.close()
[in a seperate module I have the following construct for the Dispatch]
class EventHandler:
def onData(self, event):
# do stuff with data in 'event'
cPickle.dump(data, self.fh)
# flag this as 'done'
class Async:
def __init__(self, params):
#pythoncom.CoInitializeEx(pythoncom.COINIT_MULTITHREADED) #
should this go here??
s = win32com.client.DispatchWithEvents('com_obj' ,
EventHandler)
self.finished = False
while not self.finished:
PumpWaitingMessages()
if messages_all_flagged:
self.finished = True

[python-win32] Can't access methods of COM object.
I have been successful in the past using COM from Python to control
ActiveX elements such as LabView programs and a few third-party device
servers. I recently tried to integrate a new component which came with
a LabView example and some Visual Basic sample code. The LabView example
works for me and I can examine the methods and properties of the server
but I can't seem to do anything with the server from Python.
I can successfully get an instance with:
>>>ps = Dispatch("PPServer.PPServerClass")
>>>ps
0x20239664>
>>>cha = ps.ChannelA <--- Fails
and none of the expected methods or properties are exposed except those
seen in the attached genpy file.
The VB example shows:
Set pps = New PServer
cha = pps.ChannelA
I've tried various combinations, in Python, of ps.ChannelA, ps.Start()
etc and none of the documented methods or properties seem to work.
Any thoughts on how to proceed?

works for me and I can examine the methods and properties of the server
but I can't seem to do anything with the server from Python.
I can successfully get an instance with:
>>>ps = Dispatch("PPServer.PPServerClass")
...
The VB example shows:
Set pps = New PServer
That's not the same thing. Is that actually "New PPServerClass"?
When I examine the return object, it is a PPServer not the PPServerClass
but can't find any way to go the next step.
In previous experience with LabView servers, the Dispatch statement
gives me usable COM objects.

[python-win32] Dr. Watson woes with ADO, mysql
Hello all, I've spent the last year writing an ORM in Python which I'm reasonably pleased with. But I have a recent problem: I can't seem to migrate tables from Microsoft Access (using ADO) to MySQL (using MySQLdb) without a crash. But, don't let the context fool you: when it crashes, I don't think I'm doing *anything* with the ADO connection, and I actually get the same crash when using Postgres instead of MySQL. I'm not a Windows guru by any means, but I have noticed a pattern: throughout my (many, naive) code changes to try to avoid the crash, the same functions keep popping up in drwtsn32.log: function: PyComplex_AsCComplex function: NtWaitForSingleObject (multiple times) function: NtWaitForMultipleObjects function: ZwReplyWaitReceivePortEx function: NtDelayExecution function: ScrollDC ...where PyComplex_AsCComplex is the first one listed, and (if I'm reading MSDN correctly) is therefore the function "where the fault occurred". So the question is, what's the next step in tracking down the bug? PyComplex_AsCComplex is a pretty simple function. Or am I way off-base and should be looking elsewhere?

This is probably especially true since my app doesn't handle any complex numbers (at least not in my code). I also can't find complex mentioned anywhere in the ADO COM lib (in gen_py) or in the _mysql.pyd C code (which I call directly instead of using the DBAPI wrapper). http://cvs.sourceforge.net/viewcvs.py/mysql-python/mysql/_mysqlmodule.c? rev=1.42&view=auto > Unfortunately, we are piling speculation on speculation. > Personally I would get a debug build running, so a decent > stack-trace is available, but I understand that may not be an option. ...for which I'd need vc++, right? IIRC, I'd need at least version 7? Would "Visual Studio .NET Professional Edition 2003" be okay? I can get that cheap from TechSoup. ;) I'm willing to do the research if I can just get pointed in the right direction. Thanks for the help so far!

[python-win32] Greetings and win32 com events question
Hi,
I'm new to the mailing, so greetings all!
I'm working on an application try to respond to events in Microsoft
Access using Python and win32com. However, I'm having trouble in
setting up the event handlers. I can think of 2 approaches both of
which yield win32com errors.
First is the approach used the MSOfficeEvents.py test program. The
problem is that the events to be picked up are not on the Application
object but on a Form object created from it.
class AccessEvents
def OnActivate(self):
print "Hello from Access"
return 1
self. ac = Dispatch ("Access.Application")
self. db = self. ac. NewCurrentDatabase ("d:\\pyhack\\foo")
self. fm = self. ac. CreateForm ()
self. ac. Visible = true
self. fm = DispatchWithEvents (self. fm, AcEvents)
blows out with
self. fm = DispatchWithEvents (self. fm, AcEvents)
File "D:\PYTHON22\Lib\site-packages\win32com\client\__init__.py", line
258, in
DispatchWithEvents
clsid = disp_class.CLSID
AttributeError: 'NoneType' object has no attribute 'CLSID'.
I also tried a variety of string arguments, but all of those also
yielded an invalid class id error.
The other approach is more Visual Basic like:
self. ac = Dispatch ("Access.Application")
self. db = self. ac. NewCurrentDatabase ("d:\\pyhack\\foo")
self. fm = self. ac. CreateForm ()
self. ac. Visible = true
self. ev = AcEvents ()
self. fm. OnActivate = self. ev. OnActivate
this couldn't set the OnActivate attribute with the following error.
File "D:\pyhack\1\Bob.py", line 132, in DoAccess
self. fm. OnActivate = self. ev. OnActivate
File "D:\PYTHON22\Lib\site-packages\win32com\client\__init__.py", line
503, in
__setattr__
d.__setattr__(attr, value)
File "D:\PYTHON22\Lib\site-packages\win32com\client\__init__.py", line
463, in
__setattr__
self._oleobj_.Invoke(*(args + (value,) + defArgs))
TypeError: Objects of type 'instance method' can not be converted to a
COM VARIA
NT
Anyone know how to do this, either strategy is fine.
Thanks

[python-win32] Re: Greetings and win32 com events question (Typo corrected)
Hi,
Apologies, I screwed up with a typo. AcEvents was another class
identical to AccessEvents. The problem is the same.
class AcEvents
def OnActivate(self):
print "Hello from Access"
return 1
self. ac = Dispatch ("Access.Application")
self. db = self. ac. NewCurrentDatabase ("d:\\pyhack\\foo")
self. fm = self. ac. CreateForm ()
self. ac. Visible = true
self. fm = DispatchWithEvents (self. fm, AcEvents)
blows out with
self. fm = DispatchWithEvents (self. fm, AcEvents)

258, in DispatchWithEvents
clsid = disp_class.CLSID
AttributeError: 'NoneType' object has no attribute 'CLSID'.
Second code snippet has the same screwup:
self. ac = Dispatch ("Access.Application")
self. db = self. ac. NewCurrentDatabase ("d:\\pyhack\\foo")
self. fm = self. ac. CreateForm ()
self. ac. Visible = true
self. ev = AcEvents ()
self. fm. OnActivate = self. ev. OnActivate
this couldn't set the OnActivate attribute with the following error.
File "D:\pyhack\1\Bob.py", line 132, in DoAccess
self. fm. OnActivate = self. ev. OnActivate

Welcome. As a word of warning, this is a relatively
low-activity list and I don't know what the overlap
is between this and the main python list. If you get

to try the Python list.

Well, it's not clear from your code, but the third
parameter to DispatchWithEvents should be a *class*
and not an *instance*. Since AcEvents isn't defined
anywhere within your code snippet, it's hard to
see which it is, but just in case...
That said, I can't for the life of me see why that
would raise the error you're showing, but first
things first.

It's probably considered insecure because you are passing params (%s) to python on the command line. Those "clever hackers" could find a way to pass Nasty Things, like "del C:" Performance will be intolerable, since each page request has to start and stop the Python interpreter, which is not a quick process.

Can I use import with an asp page? That's odd. When you say "stop/start iis" are you only restarting the www service? I find that the following works: open the Internet Services Manager, right click on the computer and choose "Restart IIS..." from the menu, then "Restart Internet Service on machinename". AFAICT, any code inside an .asp file will be reloaded whenever it changes. Any code within an imported .py file requires the restart I described above. FWIW I've had some issues in the past with "import myfile", and I find "from mypackage import mfile" to be more reliable. Sorry; I don't have any hard data on that at the moment--lost in the mists of history. But everything I import in .asp files sits in my site-packages folder anyway.

Re: [python-win32] Editor Replace function limitation
Thanks for both your input on this. I can recreate the problem as follows: Create a script file with the following, 123456789012345678901234567890123456789. Cut/paste into the "Find What" window, I then only get 12345678901234567890123456, that is 26 characters not 30, so I obviously can not count either. Enter var_x, including a space after x into the "Replace with" window, then hit replace. And I end up with var_x 7890123456789 Also, if I keep typing my window does not scroll as you describe. I am running the following, Python 2.3.3, wxPython 2.4.2.4, PythonWin 2.3.3 win32all build 163, and FYI, I am forced to run this version in support of CAD system.

[python-win32] Pythonwin COM problem
I have a module where I use COM to communicate with some HW drivers. In my module I use CoInitializeEx to init COM in multithreaded mode. However, when I use PythonWin to debug/test my module, I get an error due to the fact that PythonWin has (implicitly) initialized COM in apartment threaded mode. Subsequently, my module crashes Python. How, when and where PythonWin initializes COM (apartment threaded) I don't know, but the fact is it does do that since even if I remove my modules CoInitializeEx, COM works up to the point where a different thread uses a marshalled COM interface (CRASH!) If I use my module via a .py script and run that directly, everything works fine! So, how do I make sure PythonWin (implictly) inits COM in multithreaded mode? TIA /Rob Ps. I've set the sys.coinit_flags (in localserver.py) to zero (value of COINIT_MULTITHREADED), recompiled it, but that didn't change anything... ___ Python-win32 mailing list Python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

ok. I have no patches so far as of now - maybe later. Played with
Heller's ctypes for my urgent needs. That works correct with unicode
like this:
>>> import ctypes
>>>
ctypes.windll.user32.MessageBoxW(0,u'\u041f\u043e\u0448\u0443\u043a.txt',0,0)
1
My recommendation for the general style of unicode integration in win32
in future:
* output-functions should dispatch auto on unicode paramams in order to
use the apropriate xxxW-functions
* input-functions (which are used much more infrequent in apps!) should
accept an additional unicode=1 parameter (e.g.:
SetWindowText(unicode=1); please not extra xxxW -functions! thus one
can easily virtualize apps with something like
xyfunc(...,unicode=ucflag)
* or: input-functions should also auto-run unicode when a significant
string calling parameter is unicode - same as with filesystem-functions
in normal python. Example: win32api.FindFiles(u"*") is same as
FindFiles("*",unicode=1) and is better as FindFilesW("*")
Thus existing ansi apps can be converted to unicode aware apps with
minimum extra efforts.

Are you calling Dispatch before referencing the constants?
http://aspn.activestate.com/ASPN/docs/ActivePython/2.3/pywin32/html/com/
win32com/HTML/QuickStartClientCom.html
"Makepy automatically installs all generated constants from a type
library in an object called win32com.clients.constants. You do not need
to do anything special to make these constants work, other than create
the object itself (ie, in the example above, the constants relating to

[python-win32] NT Service not re-startable after reboot
I have a Python service (vmpro_pager.py) which worked fine when I wrote it a month ago. You can see the complete source code here: http://projects.amor.org/misc/browser/vmpro_pager.py It runs an SMTP proxy to clean up SMTP messages from a sender which is not compliant with the SMTP spec. Today, we found out that the service was not running, and had not been running for some time; my best guess is since the first reboot after the service was installed. Attempts to remove the service via "vmpro_pager.py remove" failed, complaining that no such service was installed. After manually deleting the appropriate registry keys, I am able to run "vmpro_pager.py install" with no problems. However, starting the service from Windows Service Manager fails with the message, "Windows could not start the Voicemail Pro Email Fixup service on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 1." The Event Log contains a single Error event with the Description: "The Voicemail Pro Email Fixup service terminated with service-specific error 1." The PYS_SERVICE_STARTED message from SvcDoRun is *not* in the Event Log. Running the service via "vmpro_pager.py debug", however, works perfectly. Although I'm certainly open to answers of the type, "here's your problem..." ;) I'd like to also where I can insert hooks to return an error code more-meaningful than "1" in the future.

MS Access Dates are best input using the #date# syntax. Here's an
example to convert a datetime.datetime object to that format:
return ('#%s/%s/%s %02d:%02d:%02d#' %
(value.month, value.day, value.year,
value.hour, value.minute, value.second))
Should be easy enough to adapt to time.time.

[python-win32] Win98 - exceptions.IOError: (13, 'Permission denied')
Hi to everyone, I have a Service, that runs on a WinXP machine. The service read a file on a Win98 machine and write the content in a file on the WinXP machine. After tree times I get the error message exceptions.IOError: (13, 'Permission denied'). The following things I have already tested: - The file on Win98 machine could be deleted, so the file is closed correctly. - Stop an restart the service on WinXP, will have no effect - Reboot the Win98 machine solve the problem for three times. So I have the same issue explained above. - I have changed the intervall from 5 sec to 1 minute. After ther first time I get the error message. - Using a Win2000 or WINXP machine instead of the Win98 machine. That works. But unfortunatly the PC to access is a Win98 and I have no influence to decide for upgrade. I can't figure out, what's the problem.

[python-win32] MS Access: silent overflow failure
Hi all,
The small demo script below makes ADO calls to a Microsoft Access (Jet)
database via win32com. But it fails in a potentially dangerous way;
"SELECT int * int;" can return None with no warning if the result is
large enough. This can also occur if one or both of the operands is a
column reference.
The same SQL run as a Query inside the Access GUI works as expected.
Manually changing one of the ints to a Single by appending ".0" works as
expected.
Any ideas about where I need to look next to find the cause of, and then
fix, this behavior?

That's my production setup, too (Apache 2, mod_python, and mod_auth_sspi), and is therefore a fundamental test case for CherryPy.

As Alex mentioned, you need to call CoInitialize for each thread.
Unfortunately, since Apache is creating the threads for you, you don't
have a hook for events to run on thread startup. Instead, you have to
watch threads as they go by and call CoInitialize ASAP. Best to do so
with a try/finally in case something goes wrong:
def handler(req):
CoInitialize()
try:
process(req)
return apache.OK
finally:
CoUninitialize()
If for various reasons that can't be made to work (some components just
aren't thread safe), another option would be to run all the COM calls in
a single thread and use a Queue; request threads would call q.put(xml,
reqid) and block, the COM thread would call q.get(), do the work, and
shove the result into results[reqid].

[python-win32] Problems connecting to an MS Access (.mdb) file
Hello folks, At work I have to use an MS Access database. Actually it's two databases (or .mdb files, anyway): One is the "master" file that contains all the relevant data in tables, and the other one seems to act a s a "GUI client" which connects to the first one. Anyway, I have to go through dozens of data records each day, but for most of them whatever it is I'm having to do could be easily automated by a script, and that's what I'm trying to do. Tthe "master" DB resides on a networked drive, and I made a local copy to test out my script. When this was finished I pointed the script at the real master, but got the error message below. According to a password recovery tool I found on the Net (passwordrecovery4msaccess.jar), neither GUI nor master DB carry a password. Ah yes, of course I've spoken to the IT guy. He doesn't like my messing with his DB. But as this very stupid task eats up a lot of my work time, I want to hack it.
