Re: Using SimpleXMLRPCServer in a Windows Service

2006-11-28 Thread Rudy Schockaert 
I found the problem.
Actually both pieces of code work now. The problem was that when I run
the SimpleXMLRPCService in a Windows Service, the STDERR needs to be
redirected to a real file. I guess some kind of buffer overflow occurs
when you don't do this.

I added the following lines:

snip
def SvcStop(self):
sys.stdout = self.stdout
sys.stderr = self.stderr
.


def SvcDoRun(self):
self.stdout = sys.stdout
self.stderr = sys.stderr
sys.stdout = file(c:/temp/my.log, a+, 0)
sys.stderr = sys.stderr

/snip

 The original (commented-out) code should be fine. You have to wait
 for 2 events: the service stop signal, or an incoming connection.
 Anyway, you always have to catch exceptions; override handle_error at least.

 Another approach (not involving events) would be to set a (not so
 big) timeout on the socket, and test for self.stop_requested on each 
 iteration.

Using SimpleXMLRPCServer in a Windows Service

Problem binding to Active Directory

2006-03-24 Thread Rudy Schockaert 
I use the following script:from win32com.client import GetObject, Dispatchuser=''password=''default_naming_context = GetObject(LDAP://rootDSE).Get(defaultNamingContext)ad = GetObject(LDAP:).OpenDSObject(LDAP://%s % default_naming_context, user, password, 1 + 512)
If user  password contain a correct value the script works. According to the ADSI documentation, replacing user and password with NULLstrings should use the credentials of the currently logged on user. In _vbscript_ this works, but in Python I get different errormessages depending on what I pass as value to these parameters.
Can somebody tell me how to do this? How can I pass a NULL-string hereThanks in advance,Rudy

CSV module and UNICODE

2006-02-23 Thread Rudy Schockaert 
I'm having problems writing unicode to a csv file.I use the following code:-import codecsimport csvcsvfile = csv.writer(codecs.open('filename.csv','w+','utf-8'))a = u'\xc9'
csvfile.writerow([a,a])
-It fails with the message: UnicodeEncodeError: 'ascii' codec can't encode .Is there any way I can solve this.PEP 305
What about Unicode?  Is it sufficient to pass a file object gotten
from codecs.open()?  For example:
csvreader = csv.reader(codecs.open(some.csv, r, cp1252))csvwriter = csv.writer(codecs.open(some.csv, w, utf-8))

In the first example, text would be assumed to be encoded as cp1252.
Should the system be aggressive in converting to Unicode or should
Unicode strings only be returned if necessary?
In the second example, the file will take care of automatically
encoding Unicode strings as utf-8 before writing to disk.
Note: As of this writing, the csv module doesn't handle Unicode
data.

Thanks a lot Skip. Sure that this will help.

Learned two things: how to do it and to look at the docs for 2.5 also.

These samples are not in the 2.4.2 reference guide.

Re: Seaching Active Directory via ADO
