DO YOU KNOW ANY THING ABOUT ISLAM???
What you are about to read might sound unusual but it could be very enlightened. So I would be thankful if you give my article 5 minute of your value time. THANK YOU Islam is a total system of living. A Muslim is supposed to live in peace and harmony with all these segments; hence, a Muslim is any person anywhere in the world whose obedience, allegiance, and loyalty are to God, the Lord of the Universe. The legal sources of Islam are the Qur'an and the Hadith. The Qur'an is the exact word of God; its authenticity, originality and totality are intact. The Hadith is the report of the sayings, deeds and approvals of the Prophet Muhammad. The Prophet's sayings and deeds are called Sunnah. The Seerah is the writings of followers of Muhammad about the life of the Prophet. Hence, it is the life history of the Prophet Muhammad which provides examples of daily living for Muslims. Muslims are required to respect all those who are faithful and God conscious people, namely those who received messages. Christians and Jews are called People of the Book. Muslims are asked to call upon the People of the Book for common terms, namely, to worship One God, and to work together for the solutions of the many problems in the society. Some Basic Islamic Beliefs 1) Belief in God: Muslims believe in one, unique, incomparable God, Who has no son nor partner, and that none has the right to be worshipped but Him alone. He is the true God, and every other deity is false. He has the most magnificent names and sublime perfect attributes. No one shares His divinity, nor His attributes. In the Quran, God describes Himself: Say, “He is God, the One. God, to Whom the creatures turn for their needs. He begets not, nor was He begotten, and there is none like Him.” (Quran, 112:1-4) Chapter 112 of the Quran written in Arabic calligraphy. No one has the right to be invoked, supplicated, prayed to, or shown any act of worship, but God alone. God alone is the Almighty, the Creator, the Sovereign, and the Sustainer of everything in the whole universe. He manages all affairs. He stands in need of none of His creatures, and all His creatures depend on Him for all that they need. He is the All- Hearing, the All-Seeing, and the All-Knowing. In a perfect manner, His knowledge encompasses all things, the open and the secret, and the public and the private. He knows what has happened, what will happen, and how it will happen. No affair occurs in the whole world except by His will. Whatever He wills is, and whatever He does not will is not and will never be. His will is above the will of all the creatures. He has power over all things, and He is able to do everything. He is the Most Gracious, the Most Merciful, and the Most Beneficent. In one of the sayings of the Prophet Muhammad , we are told that God is more merciful to His creatures than a mother to her child.1 God is far removed from injustice and tyranny. He is All-Wise in all of His actions and decrees. If someone wants something from God, he or she can ask God directly without asking anyone else to intercede with God for him or her. God is not Jesus, and Jesus is not God.2 Even Jesus himself rejected this. God has said in the Quran: Indeed, they have disbelieved who have said, “God is the Messiah (Jesus), son of Mary.” The Messiah said, “Children of Israel, worship God, my Lord and your Lord. Whoever associates partners in worship with God, then God has forbidden Paradise for him, and his home is the Fire (Hell). For the wrongdoers,3 there will be no helpers.” (Quran, 5:72) God is not a trinity. God has said in the Quran: Indeed, they disbelieve who say, “God is the third of three (in a trinity),” when there is no god but one God. If they desist not from what they say, truly, a painful punishment will befall the disbelievers among them. Would they not rather repent to God and ask His forgiveness? For God is Oft-Forgiving, Most Merciful. The Messiah (Jesus), son of Mary, was no more than a messenger... (Quran, 5:73-75) Islam rejects that God rested on the seventh day of the creation, that He wrestled with one of His angels, that He is an envious plotter against mankind, or that He is incarnate in any human being. Islam also rejects the attribution of any human form to God. All of these are considered blasphemous. God is the Exalted. He is far removed from every imperfection. He never becomes weary. He does not become drowsy nor does he sleep. The Arabic word Allah means God (the one and only true God who created the whole universe). This word Allah is a name for God, which is used by Arabic speakers, both Arab Muslims and Arab Christians. This word cannot be used to designate anything other than the one true God. The Arabic word Allah occurs in the Quran about 2700 times. In Aramaic, a language related closely to Arabic and the language that Jesus habitually spoke,4 God is also referred to as Allah. 2) Belief in the Angels:
Re: library to do easy shell scripting in Python
Wow, this message turned out to be *LONG*. And it also took a long time
to write. But I had fun with it, so ok. :-)
Michael Torrie wrote:
Recently a post that mentioned a recipe that extended subprocess to
allow killable processes caused me to do some thinking. Some of my
larger bash scripts are starting to become a bit unwieldy (hundreds of
lines of code). Yet for many things bash just works out so well because
it is so close to the file system and processes. As part of another
project, I now have need of a really good library to make it almost as
easy to do things in Python as it is in Bash. With a simple wrapper
around subprocess, I'm pretty much able to do most things. Most of my
complicated bash hackery involves using awk, sed, grep, and cut to
process text, which python does quite nicely, thank you very much. But
there's a few things to add.
To wit, I'm wanting to write a library that can deal with the following
things:
- spawn a process, feed it std in, get stdout, stderr, and err code.
This is largely already accomplished by subprocess
It is accomplished by subprocess.Popen:
The 'communicate' method handles stdin, stdout and stderr, waiting for
the process to terminate.
The 'wait' method just waits for the process to terminate and returns
the return code.
The 'returncode' attribute contains the return code (or None if the
process hasn't terminated yet).
You could write a convenience wrapper function if you want to do this in
a more terse way.
- spawn off processes as background daemons
Couldn't you do this with subprocess by doing subprocess.Popen([prog])
and, well, nothing else? (You may have/want to set stdin/stdout/stderr
too. I dunno.)
- spawn multiple processes and pipe output to input.
- can do fancier things like bash does, like combine stderr/stdout,
switch stderr/stdout, redirects to and from files
That's possible with subprocess.
See this paragraph of http://docs.python.org/lib/node528.html:
stdin, stdout and stderr specify the executed programs' standard input,
standard output and standard error file handles, respectively. Valid values
are PIPE, an existing file descriptor (a positive integer), an existing file
object, and None. PIPE indicates that a new pipe to the child should be
created. With None, no redirection will occur; the child's file handles will
be inherited from the parent. Additionally, stderr can be STDOUT, which
indicates that the stderr data from the applications should be captured into
the same file handle as for stdout.
And also http://docs.python.org/lib/node535.html. Not the least
verbose, but pretty simple, and I bet it can do anything bash can.
- transparently allow a python function or object to be a part of
the pipeline at any stage.
Hmmm. I can't think very well at the moment, but you could create
file-like objects that do...I dunno, callbacks or something.
Simple and incomplete mockup:
class Pipe(object):
def __init__(self, from_fh, to_fh, from_callback=None,
to_callback=None):
self.from_fh = from_fh
self.to_fh = to_fh
self.from_callback = from_callback
self.to_callback = to_callback
def read(self, *args, **kwargs):
data = self.from_fh.read(*args, **kwargs)
if self.from_callback is not None:
self.from_callback(data)
return data
def write(self, data):
# XXX Call the callback before or after the data is actually
written?
if self.to_callback is not None:
self.to_callback(data)
return self.to_fh.write(data)
That just passes input and output through itself, also passing it to
callback functions. You'd have to add all the other methods too, like
readline and __iter__... Maybe inheriting from 'file' would get most of
them. I dunno how it works internally.
Questions include, how would one design the interface for things, like
assembling pipes? Several ideas include:
pipe([prog1,args],[prog2,args],...)
or
run([prog1,args]).pipe([prog2,args]).pipe(...)
The former doesn't deal very well with re-plumbing of the pipes, nor is
there an easy way to redirect to and from a file. The second syntax is
more flexible but a bit cumbersome. Also it doesn't allow redirection
or flexible plumbing either.
Any ideas on how I could design this?
Ok, the below is an edited-down, more formal-sounding brain dump.
Idea 1:
run([prog, args], from_fh, to_fh, from_callback, to_callback).run(...)
It would basically just automate the construction of the intermediary
pipe objects suggested above.
It could also be done with tuples, like:
run([prog, args], (from_fh, to_fh), (from_callback,
to_callback)).run(...)
Idea 2:
This one would parse a list similar to a bash command line.
run('prog', 'out', '|', 'other_prog', 'arg', '', 'foo.txt')
Which would be like a bash:
`prog 21 | other_prog arg foo.txt`
(21 is how you combine stdout and stderr, right?)

annoying dictionary problem, non-existing keys
i use dictionaries to hold some config data,

and so on...
when i try to process conf, i have to code every time like:

this is very annoying.
in php, i was able to code only like:
if conf['key1']=='someth'
in python, this fails, because, if key1 does not exists, it raises an exception.
MY question:
is there a way to directly get value of an array/tuple/dict item by key,

i should only use it, if it does not exist, it may return only empty,

If I understand correctly you want default values for non-existing keys.
There are two ways for achieving this:
Way 1: use the get() method of the dict object:
conf.get(key, default)
which is the same as:
conf[key] if key in conf else default
Way 2: make conf a defaultdict instead of a dict, the documentation is
there:
http://docs.python.org/lib/defaultdict-objects.html
Hope this helps,

Re: @classmethod question
Scott SA a écrit :
Hi,
I'm using the @classemethod decorator for some convenience methods
and for some reason, either mental block or otherwise, can't seem to
figure out how to elegantly detect if the call is from an instance or
not.
Well, the point is that a classmethod *always* receive the class as
first argument, wether it's called on the class or an instance. If
that's not what you want, then you don't use the right tool.
Here's the problem: Within the class definition, 'isinstance' has
nothing to compare to because the class does not appear to exist.
This is NOT a great example, but it outlines the the code:
class RecipieClass:
def __init__(self):
pass
@classmethod
def get_ingrendients(self, recipie_list=None):
if isinstnace(self,RecipieClass):
return self.do_something_interesting()
else:
return do_something_boring(recipie_list)
Yes, I can test to see if the param exists, but that makes the call
exclusive i.e. I can _only_ call it as an instance or with a parameter.
Why am I doing this?
It is a series of convenience methods, in this case I'm interacting
with a database via an ORM (object-relational model).
out of curiosity : which one ?
I want the ability
to call a class-ojbect and get related values, or pass some criteria and
get related values for them without collecting the records first as
instances, then iterating them. I need to call this from several places
so I want to be DRY (don't repeat yourself).
The easiest way to describe this as an analogy would be like having a
recipie for cookies and wanting to know all of the ingredients ahead of
time. Then, at another time, wanting to know what all the ingredients
would be to make cookies, cake and bread (i.e. complete shopping list).
cookie_recipie = RecipieClass.get_recipie('cookies')
cookie_recipie.get_ingredients()
2C Flour
0.5 C Sugar
...
RecipieClass.get_ingrendients(['cookies','cake','bread'])
8C Flour
2C Sugar
...
Of course any suggestions on how this might be better approached
would be interesting too.
Why do you want the same method to do two different things ? You clearly
have two distincts methods doing different things here, and as a user of
your code I'd find your API confusing. May I suggest a much simpler
approach:
class Recipies(object):
@property
def ingredients(self):
return dict of ingredient:qty for self
@classmethod
def get_ingredients_for(cls, *id_recipies):
return dict of ingredient:summed_qty for all id_recipies
print Recipie.get('cookie').ingredients
print Recipies.get_ingredients_for('cookie', 'cake', 'bread')
My 2 cents...

Slice replacement means replace the slice with a new slice generated from

You probably want to use the synchronous method simple_bind_s() since
you want to impersonate on this LDAP connection immediately before doing
anything else on that connection.
l.result(1)

Could you please use argument trace_level=2 when calling
ldap.initialize() and examine the debug log? It records all method calls
of your particular LDAPObject instance.
l = ldap.initialize(ldap://server.net,trace_level=2)
Level 2 outputs a debug log with results received. Protect this log

on the connection., data 0, vece', 'desc': 'Operations error'}
Still something went wrong with your bind. Since I don't know your DN I
can't say anything. The DN should be a local user in this domain and not
a user from another trusted domain. If you have a complicated AD setup
with various domains and delegated trust connecting to the GC (global
catalog) on port 3268 might be easier.
The simple bind works fine and returns a result, when i get the
result, it returns 97 meaning successful.
It would raise an exception if an LDAP error was received.
So there was a successful
bind on the connection, right?
Don't know. Since I don't know your DN and AD domain configuation.
I've added a new example script ms_ad_bind.py to python-ldap's Demo/
directory illustrating all the possible bind methods:
http://python-ldap.cvs.sourceforge.net/*checkout*/python-ldap/python-ldap/Demo/ms_ad_bind.py?content-type=text%2Fplain
For getting the SASL stuff to correctly work your DNS has to be properly
set up for AD (A RRs and matching PTR RRs for the DCs).

Re: @classmethod question
On 2008-04-24 05:27, Scott SA wrote:
Hi,
I'm using the @classemethod decorator for some convenience methods and for some
reason, either mental block or otherwise, can't seem to figure out how to
elegantly detect if the call is from an instance or not.
Here's the problem: Within the class definition, 'isinstance' has nothing to
compare to because the class does not appear to exist.
This is NOT a great example, but it outlines the the code:
class RecipieClass:
def __init__(self):
pass
@classmethod
def get_ingrendients(self, recipie_list=None):
if isinstnace(self,RecipieClass):
return self.do_something_interesting()
else:
return do_something_boring(recipie_list)
Yes, I can test to see if the param exists, but that makes the call exclusive
i.e. I can _only_ call it as an instance or with a parameter.
I would turn the above method into a regular instance method
and then add a new function or static method which then
returns the summary output.
A class method is clearly wrong here, since those are meant to
be called with the class as first argument, e.g. to count
the number of instances created from a class.
Why am I doing this?
It is a series of convenience methods, in this case I'm interacting with a
database via an ORM (object-relational model). I want the ability to call a
class-ojbect and get related values, or pass some criteria and get related
values for them without collecting the records first as instances, then
iterating them. I need to call this from several places so I want to be DRY
(don't repeat yourself).
The easiest way to describe this as an analogy would be like having a recipie
for cookies and wanting to know all of the ingredients ahead of time. Then, at
another time, wanting to know what all the ingredients would be to make
cookies, cake and bread (i.e. complete shopping list).
cookie_recipie = RecipieClass.get_recipie('cookies')
cookie_recipie.get_ingredients()
2C Flour
0.5 C Sugar
...
RecipieClass.get_ingrendients(['cookies','cake','bread'])
8C Flour
2C Sugar
...
Of course any suggestions on how this might be better approached would be
interesting too.
TIA,
Scott

A couple of comments first:
- What is the significance of '[' vs. '[' ? I stripped them all out
using
The data can be thought of as a serialised object. A simple attribute
looks like:
[name someWebsphereObject]
or
[jndiName []]
if 'jndiName is None'.
A complex attribute is an attribute whose value is itself an object
(or dict if you prefer). The *value* is indicated with [...]:
[connectionPool [[agedTimeout 0]
[connectionTimeout 180]
[freePoolDistributionTableSize 0]
[maxConnections 10]
[minConnections 1]
[numberOfFreePoolPartitions 0]
[numberOfSharedPoolPartitions 0]
[unusedTimeout 1800]]]
However, 'propertySet' is effectively a keyword and its value may be
thought of as a 'data table' or 'list of data rows', where 'data row'
== dict/object
You can see how the posted example is incomplete because the last
'row' is missing all but one 'column'.
text = text.replace('[','[')
- Your input text was missing 5 trailing ]'s.
I think only 2 (the original isn't Python). To fix the example, remove
the last 'description' and add two ]'s
Here's the parser I used, using pyparsing:
from pyparsing import nestedExpr,Word,alphanums,QuotedString
from pprint import pprint
content = Word(alphanums+_.) | QuotedString('',multiline=True)
structure = nestedExpr([, ], content).parseString(text)
pprint(structure.asList())
By the way, I think this would be a good example for the pyparsing

Turn the input string (or file) into a list (generator?) of lexical objects above; then scan that recursively. The lists (or qlists) seem to have two basic forms: * properties, that is a list of the form [SYMBOL VALUE ...] which can be thought of as a declaration that some property, named by the SYMBOL, has a particular VALUE (or maybe VALUEs); and * property lists, which are just lists of properties. Property lists can be usefully turned into Python dictionaries, indexed by their SYMBOLs, assuming that they don't try to declare the same property twice. There are, alas, other kinds of lists too -- one of the property lists contains a property `[value []]' which simply contains an empty list. The right first-cut rule for disambiguation is probably that a property list is a non-empty list, all of whose items look like properties, and a property is an entry in a property list, and (initially at least) restrict properties to the simple form [SYMBOL VALUE] rather than allowing multiple values. Does any of this help? (In fact, this syntax looks so much like a demented kind of S-expression that I'd probably try to parse it, initially at least, by using a Common Lisp system's reader and a custom readtable, but that may not be useful to you.) -- [mdw] -- http://mail.python.org/mailman/listinfo/python-list

You can simple modify the dict behavior:

... if item in self:
...return super(my_dict, self).__getitem__(item)
... else:
...return ''

My point is that the recommended strategy MAY work for those who write end point applications (I consider maintaining 2 branches to be in the not working category), but it does NOT WORK for people who maintain modules for other people to use, because those people may be on a range of Python versions that extend beyond 2.6-3.0. So if I upgrade my module to 2.6, those running on earlier versions can no longer use it. At some point in the future, I'll probably be able to say no more support for pre-2.6, but it is a bit early to start saying that now. Likewise, I don't want to say no support for 3.0 - people DO want to try 3.0 out, and I WANT them to want and be able to use my module too. Given the recommended strategy, and ruling out dual codebase, whom do I tell that they can't use the next version of my module?

But it was a bit dicey there for a while, and I think other module developers/ maintainers may not be so lucky. I'm more optimistic. I tried it for Django, and while the port is not complete, it goes really well and supports basic operations (i.e. the Django tutorial). Based on your experience, and other reports, I think there is a fair chance that you can support a wide range of versions (2.x and 3.x) from a single code base for most projects. - create (if possible) single cross-version compatible code - forego support of 3.0 users - discontinue pre-2.6 support for future versions of their module - maintain dual codebase One needs to consider the drawbacks in each case; for the single codebase approach, the drawback probably is that readability suffers, and the need for testing increases (but it does always if you support multiple targets). It also requires expertise to create such cross-version code in the first place, but that's just a learning issue (i.e. you have to keep the rules in mind that you want to follow).

Billing system written in python
Hi, I would like to develop a billing system for a cable tv system, basically what it does is have subscribers in db, compute billing statement, print for statement for distribution something like that. I was evaluating jbilling its a java base billing system that uses tomcat,mysql or postgress DB and java. Im looking similar to this but its written in python so that I wont start from scratch. Why not use jbilling instead if it solve you problem? Will the reason Im looking for a python solution is I want to learn python and java is bit complicated for me at this time since Im just a newbie in programing. Any suggestion? I was thinking of using django but Im more looking in to a ready made billing system that I will just do some tweaking and fine tunning to meet our need. like jbilling.

Re: Ideas for parsing this text?
Thanks to everyone for the help and feedback. It's amazing to me that
I've been dealing with odd log files and other outputs for quite a
while, and never really stumbled onto a parser as a solution.
I got this far, with Paul's help, which manages my current set of files:
from pyparsing import nestedExpr,Word,alphanums,QuotedString
from pprint import pprint
import re
import glob
files = glob.glob('wsout/*')
for file in files :
text = open(file).read()
text = re.sub('\[',' [',text) # These 2 lines just drop double quotes
text = re.sub('\]','] ',text) # that aren't related to a string
text = re.sub('\[\]','None',text) # this drops the empty []
text = '[ ' + text + ' ]' # Needs an outer layer
content = Word(alphanums+-_./()*=#\\${}| :,;[EMAIL PROTECTED]%%) |
QuotedString('',multiline=True)
structure = nestedExpr([, ], content).parseString(text)
pprint(structure[0].asList())
I'm sure there are cooler ways to do some of that. I spent most of my
time expanding the characters that constitute content. I'm concerned
that over time I'll have things break as other characters show up.
Specifically a few of the nodes are of German locale.. so I could get
some odd international characters.
It looks like pyparser has a constant for printable characters. I'm
not sure if I can just use that, without worrying about it?
At any rate, thumbs up on the parser! Definitely going to add to my toolbox.

[ open-list

open-string (not close-string!)

so it also looks as if strings aren't properly escaped.
This is definitely not a pretty syntax. I'd suggest an initial
tokenization pass for the lexical syntax
[ open-list

[open-qlist

Correct nesting should give you two kinds of lists -- which I've shown
as `list' and `qlist' (for quoted-list), though given the nastiness of
the dump you showed, there's no guarantee of correctness.
Turn the input string (or file) into a list (generator?) of lexical
objects above; then scan that recursively. The lists (or qlists) seem
to have two basic forms:
* properties, that is a list of the form [SYMBOL VALUE ...] which can
be thought of as a declaration that some property, named by the
SYMBOL, has a particular VALUE (or maybe VALUEs); and
* property lists, which are just lists of properties.
Property lists can be usefully turned into Python dictionaries, indexed
by their SYMBOLs, assuming that they don't try to declare the same
property twice.
There are, alas, other kinds of lists too -- one of the property lists
contains a property `[value []]' which simply contains an empty list.
The right first-cut rule for disambiguation is probably that a property
list is a non-empty list, all of whose items look like properties, and a
property is an entry in a property list, and (initially at least)
restrict properties to the simple form [SYMBOL VALUE] rather than
allowing multiple values.
Does any of this help?
(In fact, this syntax looks so much like a demented kind of S-expression
that I'd probably try to parse it, initially at least, by using a Common
Lisp system's reader and a custom readtable, but that may not be useful
to you.)

convert xhtml back to html

Re: Problem using copy.copy with my own class
George Sakkis wrote: First off, inheriting from a basic builtin type such as int and changing its constructor's signature is not typical; you should rethink your design unless you know what you're doing. Nah, I would never claim to know what I'm doing. However, I have to say that I have been finding this technique very useful. When I started developing this program, I used an int. Then I discovered that I needed to have a string associated with the int. By subclassing int to add a string, I managed to make the change transparent to the code I had already written. Only the new code that needed the associated string knew that it was available. In another case, I subclassed str so that I could have a long form for a string (e.g., a full name attached to the surname). Are these applications of subclassing bad form? What is the motivation for your warning? One way to make this work is to define the special __copy__ method [1], specifying explicitly how to create a copy of a Test instance: Normally (i.e. for pure Python classes that don't subclass a builtin other than object) copy.copy() is smart enough to know how to create a copy without an explicit __copy__ method, so in general you don't have to define it for every class that has to be copyable. Yes, I noted in my original posting (which seems to have fallen off this thread) that the __copy__method solved the problem (at least on one platform). However, I was wondering why it was necessary when what I was defining was supposedly the default action. Thanks for your explanation. The traceback is not obvious indeed. It turns out it involves calling the arcane __reduce_ex__ special method [2] defined for int, which returns a tuple of 5 items; the second is the tuple (class '__main__.Test', 0) and these are the arguments passed to Test.__new__. So another way of fixing it is keep Test.__new__ compatible with int.__new__ by making optional all arguments after the first: This suggestion is very interesting. It seems to be an alternative to the solution suggested by Gabriel. The reference that Gabriel provided includes the statement: Instances of a new-style type C are created using obj = C.__new__(C, *args) where args is the result of calling __getnewargs__() on the original object; if there is no __getnewargs__(), an empty tuple is assumed. Gabriel's solution using __getnewargs__ assures that args receives a non-empty tuple. Your solution renders the empty tuple impotent by specifying default values. Correct me if I am wrong. I would be interested in a translation into English of the following statement from the same reference that Gabriel provided: Implementing this method [i.e., __getnewargs__] is needed if the type establishes some internal invariants when the instance is created, or if the memory allocation is affected by the values passed to the __new__() method for the type (as it is for tuples and strings). What is an internal invariant? How do I know when the memory allocation is affected? Does my Test class affect the memory allocation? As a sidenote, your class works fine without changing anything when pickling/unpickling instead of copying, although pickle calls __reduce_ex__ too: from pickle import dumps,loads t = Test(0, 0) assert loads(dumps(t)) == t Perhaps someone more knowledgeable can explain the subtle differences between pickling and copying here. I have a situation in the full program where pickling seems to be failing in the same manner as copy, but I have not been able yet to reproduce the problem in a simple test program.

Well, maybe there's a simple way to do that with regexps, but my simpleminded img[^(/)]+/ doesn't work. I'm not enough of a regexp pro to figure out that lookahead stuff. I'm not sure where to start now; I looked at BeautifulSoup and BeautifulStoneSoup, but I can't see how to modify the actual tag. You could filter the XHTML through mxTidy and set the hide_endtags to 1: http://www.egenix.com/products/python/mxExperimental/mxTidy/ -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Apr 24 2008) Python/Zope Consulting and Support ...http://www.egenix.com/ mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ mxODBC, mxDateTime, mxTextTools ...http://python.egenix.com/ Try mxODBC.Zope.DA for Windows,Linux,Solaris,MacOSX for free ! eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.

I have looked into passing command line arguments to python and can send a specific pathname to python but ideally what i need is a generic command that i can write to the registry that passes the pathname of whichever file was doubled clicked!?! am i asking too much/does it exist/is there an easier way to do this!! CC I did this by writing the path to me script or exe and added %1 to the end, which basically means that my program can (or requires) a parameter passed to it. Here's an example: C:\Program Files\PyMail\wxsendmail.exe %1 That should work. Tested on Windows XP SP2 with Python 2.4/2.5. Mike -- http://mail.python.org/mailman/listinfo/python-list
Re: python-ldap - Operations Error
Thanks for the help guys, it works! I used the ldap.set_option(ldap.OPT_REFERRALS, 0) from http://peeved.org/blog/2007/11/20/ immedialtey after import, then did the initialize trace_level=2 and did the simple_bind_s. I was able to search and get the results. That trace_level thing is nice, i'm sure i will be debugging this more as i move forward :) Not sure if this is an AD thing or just something i needed to do with our particular server/config. Thanks again! -- http://mail.python.org/mailman/listinfo/python-list
