COM problem .py versus .exe
I have a .DLL that I am extracting the file version from using wmi.py.
The specific code is:
c = wmi.WMI()
for f in
c.CIM_DataFile(Name="c:\\glossersdmsservices\\bin\\glosscmanager.dll"):
sdmsver = f.Version
this works fine when running the application as a python file, when I
build the application into an executable, using py2exe, I get the
following error:
Traceback (most recent call last):
File "autoStart.pyc", line 241, in test
File "wmi.pyc", line 138, in ?

KeyError: '{D2F68443-85DC-427E-91D8-366554CC754C}'
the .dll resides outside the directory of the executable. The one
thing I notice is that the KeyError value is a different id than the
COM object I am accessing. I'm not sure where the value in the
KeyError listed is coming from. Do I have to do some preprocessing in
the build script? I am at a bit of a loss here, so any input would be
appreciated. Thanks in advance.

Not quite true. Objects are typed in Python:
py> type('')
py> type(1)
but names ("variables", almost) can be dynamically changed from one type
to another:
py> x = 1 # x starts as an int
py> x = '~' # now it is a string
py> x = [1] # and now a list
Even though names can refer to an object of any type, the actual
objects themselves are always strongly typed: "hello" is always a
string, {} is always a dict, and so on.
The best use of Hungarian notation is the original use, as introduced in
the application development team at Microsoft (before the operating system
team got their hands on it, and broke it).
Rather than prefixing variable names with the type which the compiler
already knows (eg "sName" for a string, "iAge" for an integer), the
original use of Hungarian notation was to use a prefix which explains what
the data is for: the "type" of object, but not types which compilers
understand.
Here are some good uses for Hungarian notation:
ixCurrent = 0 # ix~ means index into a list or array
cFound = 0 # c~ means a count
dxObject = object.width() # d means difference
No compiler in the world can tell that adding the width of an object in
pixels to the count of how many objects were found gives a meaningless
result. But a human programmer should immediately see the bug in:
ixHam = dxEgg + cTomato
even if they don't remember what Ham, Egg and Tomato represent.
Remember that space probe a few years back that crashed into Mars because
some NASA engineer forgot to convert metric to imperial or vice versa?
That sort of mistake is easy to make when you have something like this:
initialSpeed = 3572.8 # feet per second
# ~~~
# five pages of code
# ~~~
deceleration = 3.5 # metres per second squared
# ~~~
# five more pages of code
# ~~~
timeNeeded = initialSpeed/deceleration
Now imagine seeing this line instead:
timeNeeded = iInitialSpeed/mDeceleration
With just a glance you can see that there needs to be a conversion from
imperial (i~) to metric (m~) or vice versa, or else your $20 billion
dollar space probe turns the engines off too early and becomes a $20
billion hole in the ground.
The history and justification for Hungarian notation is explained here:

You could try using the tweaked version 0.6b from:

which doesn't use the EnsureDispatch and so doesn't

pulling multiple instances of a module into memory
I have a Python app, spam.py, that uses a C shared library, eggs.so.
This shared library is an interface that makes connections to another
system (Ham), and among other things uses callback functions.
Therefore, if I want to make multiple connections to Ham, I need
eggs.so to be instantiated in memory multiple times so that everything
works fine.
Right now, in spam.py, let's say I want to make two connections to the
Ham system. I call
eggs.start('Connection1')
eggs.start('Connection2')
On the second one, I get a 'duplicate call' error. Because Python is
optimized to only load a module into memory once, I can never make more
than one connection from the same Python script.
Any ideas to work around this would be great.

Unfortunately, I've seen that behavior a number of times: no output is None, one output is the object, more than one is a list of objects. That forces you to have checks for None and list types all over the place.

Re: tkinter radiobutton
>> to determine if it is selected?, or can this only be achieved via >> control variables? > The value and variable options for a radiobutton seem to be what > you're looking for. Thanks, I knew that, but I was looking for a way to read the selected/unselected status directly. Using control variables gets a little messy because of the relationship of the rb matrix. They are arranged in a 4 X 4 matrix where each column is grouped (via intVars) so that no more than 1 rb per column can be selected, but each row makes up the 'status' on one 'item' so any combination of buttons in a row is acceptable. One solution I have been contemplating requires setting the value of each rb to the row number ( 0, 1, 2, or 3 or 1,2,3, or 4 in case I need to use 0 for 'none selected'), and using one intVar for each column. Then I would have to loop through all four intVars four times to determine which radiobuttons are selected in each row. That's what I mean by messy.

What advantage does this really give you over indicative > doc strings? interfaces in particular are a modern madness. Interfaces, IMHO are best viewed as documentation. I have used the Zope 3 interfaces module, and I think it's going to be very useful to me. Although, theoretically, you could do all of this with doc strings, being able to check that you've documented everything that should be (including methods and attributes). With interfaces, you distribute the docstrings over the class. Also, the interpreter helps you with documentation problems, because standardized means are used to represent what methods expect as arguments, and so on. They don't really force you to do it that way, but they generally catch broken attempts to implement the interface. > Why not just define a class with a set of unimplemented methods. Takes too much time, and gets mixed in with functionality. Basically, it's more boilerplate than the better interface modules written for Python. > Who cares if someone tries to instantiate it?

Yes -- there's just no reason to do that in Python. Properties mean you don't have to worry about an attribute changing into a method, so there's no reason to try to "preempt the damage". No damage, so no preemption needed. I personally, really prefer attributes (or properties) over explicit get/set methods. > > Unless you have designed the software interactions completely > bevorehand > > (which never works out) this is the only way to incorporate > changes without > > refactoring your source all the time. > > On really big projects it is fairly normal to define the > structure of the code to quite a detailed level - often > using Case tools and UML etc - so refactoring is only needed > when you discover a hole.

This makes sense if the software is: 1) Designed by one institution. 2) Designed almost entirely before deployment. 3) Not designed to be worked on by users and semi-trained developers. In other words --- proprietary software. For a free-software application, in which you want to maximize your collaborative advantage, you want to make one-sided cooperation as easy as possible. I do not *know* who my collaborators will be. They may well not be privy to UML diagrams and CASE tools I may have used. Certainly a lot of them wouldn't bother to look if they could avoid it. OTOH, a well-defined set of interfaces shows them where they can make clean breaks in the design in order to localize what they need to learn and what they need to fix -- and it's all right there in the source code. It's just like fixing an old house. The biggest problem is knowing where to stop --- how much of that plumbing do you want to take out and rework? If it has cutoff valves and unions in the right places, it will come apart in sections and you have a much better chance of fixing it without getting into an intractable mess. Software interfaces can be used to the same effect --- making the job easier for the next person who comes along. If you are trying to trade on a free-software advantage, then it is absolutely in your best interest to make the way as easy as possible for the people who follow you. > > this should be expanded further, i.e. more build-in decorators > for > > interfaces, abstract classes, parameter and return value > restrictions. Specifically, *I* would like one of the available interface implementations to find its way into the standard library. Obviously, *my* life would be easier if it's the Zope 3 implementation, but I'll learn to use whatever gets in there. > What kind of parameter and return value restrictions? > In a dynamically typed language there is a limit to what can > be applied, and much of that is of limited value IMHO. Yes, there is a limit, and it's madness to go beyond it. But there is a useful middle ground. For example, it is quite useful to specify that an argument of a method should expect an object which implements a given interface. For simple objects, this is usually handled by things in the interface module. A method which expects a number may check that the object has __add__, __mul__, etc. But the real win is when it's supposed to be a much more elaborate object defined by the application. Intelligent use, of course, will suggest many cases where constraint is unnecessary boi

My mistake :-S
The comment in the code was erroneous, I shouldn't write messages to

'unless' works as 'if not', not as 'while not'. Sorry for that :-)
Anyway, it does improve readability. I know that it doesn't necessarily
makes code better, but it's a nice "trick" that I like :-)
Other nice thing about ruby is declaring regexps as /regexp/ rather
than having to re.compile("regexp"), and having a built-in operator to
match against them (of course, as everything in ruby, overloadable in

There has been recent discussion about this. Check the python-dev list archives I think. It's unlikely that all of numeric/numarray could go into the Python stdlib because there still is disagreement between the two camps as to the module architecture. However, there does seem to be some agreement at the level of the basic array object, so it may be possible that at least the array object itself might join the stdlib in the not too distant future.

Python + Lisp integration - Part II
I'm posting a self-followup to my post in last December about Python and Lisp integration: http://groups-beta.google.com/group/comp.lang.python/msg/ff6345845045fb47?hl=en> Now, just yesterday I just stumbled upon Lython: http://www.caddr.com/code/lython/> It's a bit edgy but it can be made to work :-). It does do simple macros and compiles to Python bytecode (via AST generation). So, effectively you could be writing your code in Lisp and then running it in the vast environment of Python standard library and modules.

RE: Running Python interpreter in Emacs
It works for me in W2000; I have an ancient .emacs file that someone gave me

Absolutely. I've really tried to use Eclipse - it's the standard editor for my current project (Java - blegh!). I *hate* it. It's huge, bulky, slow ... I've gone back to my text editor. I'm a hell of a lot more productive because the IDE isn't getting in my way. The only IDE I've ever actually liked using was Metrowerks CodeWarrior (on MacOS classic). Simple, unobtrusive.

Tom, I found that controlling the firewall via popen3 is perfect, I
now have server applications that can firewall themselves when they
detect possible attacks or abuse from individual IPs, ranges etc
eg:
import win32pipe as W
#add a rule at position 100
i,o,e = W.popen3('C:\\ipfw\\bin\\ipfw add 100 allow IP from me to 192.0.0.1')
-or-
# list all rules
i,o,e = W.popen3('C:\\ipfw\\bin\\ipfw list')
-or-
#delete rule 100
i,o,e = W.popen3('C:\\ipfw\\bin\\ipfw delete 100')
Thanks again

Please tell us what you do more precisely:
* do you send the "info" as an attachment using the email package?
* do you create alternative text and HTML parts for the body?
I have never managed to send plain text email and receive it as HTML.
Perhaps you mean that some "smart" client does something stupid with
your text, eg. it removes line-breaks you have in your message?
Try this:
import smtplib
def send(server, from_whom, to_whom_list):
smtp = smtplib.SMTP(server)
smtp.sendmail(from_whom, to_whom_list,
"""From: %s
To: %s
Subject: test email
This is a test.
It has line breaks.
Does it come as three separate lines?""")
I tried it as
send('localhost', '[EMAIL PROTECTED]', ['[EMAIL PROTECTED]'])
and I had no problem. What happens for you (substitute other server and
email addresses, obviously :) ?

Re: Photo layout
Thanks! This works well -- I was letting myself be too intimidated with
reportlab before looking at the documentation, but it was really not
hard at all. I think I figured out how to do landscape mode too.
from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import letter
def insertPicture(c):
c.drawInlineImage("geese1.jpg",100,100,200,150)
width, height = letter
letter = height, width # change to landscape
c = canvas.Canvas("picture.pdf",pagesize=letter)
insertPicture(c)
c.showPage()
c.save()

They did it with Gush: (I think) http://2entwine.com/ It's a py program that embeds Flash very nice. -Jim On 27 Jun 2005 15:11:11 -0700, Grops <[EMAIL PROTECTED]> wrote: > Flash and Python could be a VERY powerful pair of tools for building > quick apps, Yet I don't see much on the web about it. > > I was excited to see that it is possible to make them play together > here: > http://www.klaustrofobik.org/blog/archives/000235.html > > Unfortunately, these folks seem to have gotten stuck on compiling the > py files to exe, and since I don't see reference to it anywhere else, I > was wondering if anyone here knew why it didn't work, or if anyone had > ideas about how to make it work. > > Normally I would put some test code here, but I'm way out of my league. > Just insanely curious... > > Any thoughts??? > > > Thanks, > -J > > -- > http://mail.python.org/mailman/listinfo/python-list > > -- http://mail.python.org/mailman/listinfo/python-list

There's no way you can control what the recipient's mail client does, however. In particular, there are a lot of mail clients out there that handle tabs poorly. Outlook Express is the poster child for this: it ignores tabs completely, however it is by no means the only culprit. It's simply the most widespread one. In other words, use strings of spaces rather than tabs, and you'll probably find your messages coming out looking better. John Roth > -- http://mail.python.org/mailman/listinfo/python-list
