voici ce que je trouve dans le journal d'evenement :
The instance's SvcRun() method failed
<Error getting traceback - traceback.print _tb() failed
<class 'pywintypes.com _error'>: (-2147221020, 'Syntaxe incorrecte',
None, None)

Try with a small sample application then adding
more functions, to see where it fails.

I found the function which starts the error
*************** *************** ****
class Win32ProcessUsa ge:
def __init__(self):
self.lstProcess =[]
self.WMIService =
win32com.client .GetObject(r"wi nmgmts:{imperso nationLevel=imp ersonate}!\\.\r oot\cimv2")
self.reset()
def reset(self):
self.lstProcess =[]
lstTmp = self.WMIService .ExecQuery('Sel ect * from
Win32_Process')
for item in lstTmp:
self.lstProcess .append(tuple([item.Name,item. CommandLine,ite m.Status,item.P rocessId,item.P arentProcessId]))
def get_usage(self) :
return self.lstProcess
*************** *************** ****
it is a class which allows to obtain the list of the processes who run.
With python interpreter, this class functions very well but , when it
turns in service, it starts the error :
The instance's SvcRun() method failed
<Error getting traceback - traceback.print _tb() failed
<class 'pywintypes.com _error'>: (-2147221020, 'Syntaxe incorrecte',
None, None)
Why ???
ok,
It's this line who crash the service :
self.WMIService
=win32com.clien t.GetObject(r"w inmgmts:{impers onationLevel=im personate}!\\.\ root\cimv2")
why this function goes when it is not a service?
with IDLE -ok
with py2exe executable (no windows service) -ok
with py2exe service option true (windows service) -CRASH....

OK. I think I can help here. WMI is a COM/DCOM-based technology.
Windows services are inherently multithreaded. Therefore you need to
Initialize a COM threading model specifically even though you're not
really using threads yourself.
Try putting:
import pythoncom
pythoncom.CoIni tialize ()
somewhere before the line which instantiates the WMI
object (the one you quoted above).
I have no idea why this usually manifests itself as a
"Syntax Error" but it does!

Hi,
I'm currently stuck with a big problem. I must develop a Windows service
and an application to configure it and display what is happening. The
problem is not really on the service side, but on the application side. I
explain:
The service is composed of a kernel dynamicaly loading plug-ins modules and
starts the process of each module. Until nous, it's not that hard.
The hard part is when it comes to the application to configure...

I have a Windows Service in C# talking to a serial port and using Remoting.
It also uses several COM objects. On customer's computer the service will
occassionally hang somewhere - the service still shows on a Task Manager
list. In Services it says it is still running. However there is no way to
stop it other than by rebooting the whole computer. No exception (including
non-CLS) is ever generated. I added a separate System.Timers.Timer...

Is there ANY way for a windows app to consume a web service by going
through a SOCKS proxy? This is a MUST for me because the windows app I
am building will be deployed to many corporate clients who are behind
SOCKS proxies.
My app also has corporate clients that are behind a HTTP proxy. Is
there a way for the windows app to consume a web service through a
HTTP proxy?
Please post any relevant code you have, THANKS!

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
