py2exe help
python help, I'm open for suggestions. I'm using py2exe to compile a working program. The program runs and prints fine until I compile it with py2exe. After compiling the program, it runs fine until it tries to import the win32ui module, v2.6214.0. Then, I get a windows error message: ImportError: Dll load failed: This application has failed to start because the application configuration is incorrect.

Re: Problems running on HP Intel duel core machine
On Thursday 11 December 2008 I wrote about the problem that I was having importing win32ui from within a program I wrote. This was happening only on some computers but not all. The win32ui module is used for printing. I never solved the problem until today. I installed only winXP on a hard drive and started from there. I ran my program and incurred an error message that a some of my clients were getting; importError: Dll load failed: The specified module could not be found. Next, I loaded the installation software that came with an HP OfficeJet. Problem Solved. Apparently HP software is installing a file or files that python does not contain( I had a client load python ), and py2exe is not including in its package. 'load_dynamic' help says this: (Note: using shared libraries is highly system dependent, and not all systems support it.) I wonder if they tried installing an HP? jim-on-linux http://inqvista.com py help, I produced a program that runs on windows. One client is using an HP machine with an Intel cpu E2200 @ 2.2ghz., and with .99 G ram. The machine is using Win XP Pro 32 bit OS with service pack 2 I ran Dependency Walker and everything is OK. I used py2exe to build the exe file with bundle files:1 and also 3, with the same traceback results. I created a test print module that imports both win32api and win32ui modules and its only job is to print a page of text. The first module that is imported is win32api. line 8 of that module adds to the path the module named 'win32api.pyd'. The import is is completed without error. The next module that is imported is win32ui. line 8 of that module adds to the path a module named 'win32ui.pyd'. The search for the win32ui.pyd module seems to be the cause of the problem. Traceback: ImportError: Dll load failed: The specified module could not be found. Both modules 'win32api.pyd' and win32ui.pyd are in the same directory. Below is a copy of the win32ui.py module. The only difference between this and win32api.py module is the name that is installed when creating the path. def __load(): import imp, os, sys try: dirname = os.path.dirname(__loader__.archive) except NameError: dirname = sys.prefix path = os.path.join(dirname, 'win32ui.pyd') #print py2exe extension module, __name__, -, path mod = imp.load_dynamic(__name__, path) ##mod.frozen = 1 __load() del __load The only difference I can find is that this program works fine on every machine that it is tried on except the HP duo core machine, with Intel E2200 cpu.

This is a consept of how to do what you want,
but you will have to work a little to get it
right.
You might try something like this;
Dict = {} ##create a dictionary
make a list of all column3 values
for loop colum3 values
Make these values the key in a dictionary
If the values are long, you can use the first
7 to 15 characters if you want.
use this key to equal all the values in the
other columns on the same row.
Dict[column3] = column1, column2, column3
once the dictionary is made
get the dictionary key
x = Dict.keys() ## get the keys from Dict
x.sort() # produce a sorted list of keys of
column3
Loop these sorted keys to extract from the
dictionary the values related to each

I'll look for hours and find one or two places, but they never respond to my messages, so I figure they must not do that kind of art work. I'm looking for both: a collection of graphics and some place (or someone) that can make custom original graphics. The latter is just for future reference.

put other stuff into the master using another

If you make all buttons the same size inside

In the above program, why the error comes
??
This example works.
I only used carriage return and spacebar for
formatting.
You are using '\xc2' whatever that
represents, I'm not sure. But if you
carriage return at the end of each line then
delete until the next line comes to the
cursor then use only space bar and carriage
return (Enter) to format you will fix it.
Or copy below and paste into your file.

Re: gui toolkits: the real story? (Tkinter, PyGTK, etc.)
On Monday 01 October 2007 21:04, bramble wrote: What is the backstory to why Python includes Tk bindings, as opposed to some other set of bindings? I've written a few little Tkinter-based apps, and it's nice and simple. I like it well enough. That said though, I keep feeling the gravitational pull toward GTK+. I've been meaning to get the whole glade+gtk+python thing happening with my own projects, as soon as time allows. Is there resistance in the upper Python echelons to GTK because of its LGPL licensing? Reading Alex's Nutshell book, right off the bat he comments that The most popular Python GUI toolkit today is probably wxPython. But then he goes on for 45 pages on Tkinter... Seems like he wanted to write that chapter on wx instead... WxWidgets, the last time I looked at it, seemed awfully like MS Window's MFC. The licensing seemed vague at the time, and it looks like wx contains an extra layer of GUI library, so I didn't spend any real time on it. But, regardless, it seems to get good press among python folk (I think I remember ESR noting how it was his GUI toolkit of choice). PyQt has had that issue (IIRC) about needing to pay for it for commercial apps, so I can see how there might be resistance to it being considered the standard Python GUI toolkit. So, it would seem to me that Tkinter *might* remain in Python proper, but that I probably wouldn't see much effort put into it. Well, the Python standard library docs tell a different story. There's stuff in there about Tix, ScrolledText, turtle, and then the other GUI packages doc page goes on about Python megawidgets (Tk-based) and Tkinter3000 Widget Construction Kit (WCK). Wow. Looks like Tkinter is still having serious support -- even though in that same doc at the bottom notes, PyGTK, PyQt, and wxPython, all have a modern look and feel and far more widgets and better documentation than Tkinter. So, that leaves me wondering, why is Tkinter still getting so much focus in the Python standard library? Maybe a better question is, how has Tk managed to keep beating up the newer, more modern, more featureful, better documented toolkits encroaching on his territory? What's Tk's secret weapon? Tkinter's secret weapon are pgmrs like me that would rather put pressure on the Tk people to improve what already is working. Update and improve Tk, change the look and feel of it, add features. Let me spend my time programming not trying to make existing programs compatible with the unknown. (Some change to who knows what.) On the other hand, questions like yours are exactly what keeps the pressure on the Tkinter people to upgrade.

I am having a terrible time trying to get a pack() layout working. I have three frames stacked top to bottom and stretching across the master window from edge to edge. Crude ASCII Art rendition of the frames: | header | | body | | log| I want the header and log frames to have a fixed height (and stick to the top and bottom, respectively, of the master frame) and the body frame to expand to fill the rest of the space, for instance if the window is maximized. Here is a simple script that /almost/ does what I want. I've been tweaking the pack() options for three hours and I just can't seem to get the effect I want. This /can't/ really be this hard can it? If you run the script, be aware that since there are only frame widgets the window will initially be very very tiny. If you expand or maximize the window you'll see a thin black frame at the top, yay, a thin white frame at the bottom, yay, but the middle grey body frame will NOT span the Y axis, boo. It's there, and stretches from side to side, but it refuses to stretch top to bottom. Adding a widget (say, a Text) doesn't help, the light grey non-frame rectangles remain. My investigations seem to indicate that the light grey bars are part of something the Tk docs call a parcel that each slave widget gets packed into. Apparently the header and log frames don't use their entire parcels, but I don't know how to get the parcels themselves to shrinkwrap to the size of the actual Frame widgets. In any event, my head's sore and I'm just about ready to take out some graph paper and use the grid() layout manager instead. But I really want the automatic resizing that the pack() manager will do, rather than the static layout grid() will give me. Any thoughts or advice? Sorry I can't help you with pack, I don't use it anymore. I am able to do everything with grid that I can do with pack. Once I learned to use grid I liked it better than pack.

I'm guessing you're running into a situation like this: Module A imports module B and then defines an important class. Module B imports A (which does nothing because A is already partially imported) and then defines a class that depends on the class that is defined in module A. That causes a NameError. The root of the problem is that all statements are executed in the order in which they appear, and B is imported before A had a chance to define the class that B depends on. Note that import statements don't have to be at the top of the file. I agree, waite until python complains. You might try to remove all of the import statements then add then as they are requested by the program by a traceback error. jim-on-linux Try moving each import statement to the latest possible point in the code, i.e. right before the first occurence of whatever names you're importing from the respective modules. That way, each module gets to define as much as it possibly can before it gets side-tracked by importing other modules. If my guess doesn't help, you're going to have to post at least the exception/traceback you're getting, and you're probably going to have to post some code, too.

Many APIs that exchange data choose to exchange text in Unicode because that eliminates encoding uncertainty. Whether an API uses Unicode would probably be noted somewhere in its documentation.

For some reason the unicode u is removed. I havn't wanted to spend the time to figure out why. As a software engineer, I'd get worried if I didn't know why the code I wrote works. Maybe that's just me. I don't disagree, but sometime depending on the situation, time to investigate is a luxury. However, ( If you don't have the time to do it right the first time when will you have the time to fix it.) Unicode is not rocket science. I suggest you read http://www.amk.ca/python/howto/unicode to demystify what Unicode objects are and do. With str(), you're asking the Unicode object for its byte string interpretation, which causes the Unicode object to give you its encoding in the system default encoding. The default encoding is normally ascii. That can be tweaked for your particular Python installation, but if you need an encoding other than ascii it's recommended that you explicitly encode and decode from and to Unicode, lest you risk writing non-portable code. Using str() coercion of Unicode objects will work well enough until you run into a string that contains characters that can't be represented in the default encoding. Right, even though None or null are not strings they are common enough to cause a problem. Try to run a loop through a list with None or null in it. Example, x = str(list[2]) when list[2] = null or None, problems. Easy to fix but more work. I'll check the web site out. Thanks for the update, Jim-on-linux Once that happens, you're better off explicitly encoding the Unicode object into a well-defined encoding on input, or, even better, just work with Unicode objects internally and only encode to byte strings when absolutely necessary, such as when outputting to a file or to the console. Hope this helps, Carsten. -- http://mail.python.org/mailman/listinfo/python-list

I guess what's happening is that there's some optimization that avoids creating two separate float objects for a float literal that appears twice, and that optimization doesn't see the difference between 0. and -0. x, y = 0., -0. id(x) == id(y) True jim-on-linux's solution works in the interpreter, but not in a script, presumably because we've got file-wide optimization rather than line-by-line optimization. #test.py x = -0.0 y = 0.0 print x, y #end test.py import test -0.0 -0.0 Mark This is the only way I could make this work in a script. from decimal import Decimal x = Decimal( -0.0) y= Decimal(0.0) print x,y x = Decimal( 0.0) y= Decimal(-0.0) print x,y jim-on-linux http:\\www.inqvista.com -- http://mail.python.org/mailman/listinfo/python-list
SQLite3 trapping OperationalError
pyhelp, I set up a table in SQLite3. While running other modules I want to know if a table exists. SQL has a command List Tables but I don't think SQLlite3 has this command.

Re: can't find a way to display and print pdf through python.
I'm using Suse Linux which has five program that

Acrobat Reader is one of the five.
A right button click on the file should give a

Im using a KDE desktop
Open a shell, add the path to the directory where
the PDF file lives, and on the command line type;
xpdf myfile.pdf ## may also work on a Gnome

or any of these for the KDE desktop;
kpdf myfile.pdf
Kghostview myfile.pdf
konqueror myfile.pdf ## my browser + myfile.
Acrobat Reader is also listed on my system. It
open files as adobe reader using the mouse to
open a pdf file but not from the command line
with an arg, and I haven't spent the time to
figgure out why.
You will have to import os and some combination of

os.execvep() ## or others like execl, execle

Thanks, However, using note to print is a problem. First, because note adds a header( file name etc.) to the printed output that is not acceptable. Next, the number of files is 200 to 300 per day.

Easiest way to print from XP/DOS.

I've built a single file utility using py2exe. I
zip the dist directory and send it to the client.
For clients that use win95, win98 machines,
They unpack the zip file and run the exe.
The utility creates a text file that is sent to
the printer with the statement below.
os.system('type ' +FileName+ ' prn'),
and the file prints.
But, from an xp machine if I try to print using
the same statement, I get a question on the dos

Which program authorized this operation?
Since I don't have an xp machine, the statement

If not, I may have to register the package in xp,

members in an arbitrary order are now ordered.
There is also the `SequenceOrderedDict
http://www.voidspace.org.uk/python/odict.html#
sequenceordereddict`_ that behaves like a
sequence as well as a dictionary. It allows
slicing and the keys, values and items methods
are special sequence objects (which are also
callable and so behave as methods too).
What's New ?
==
Code
---
Removed the TODO and CHANGELOG sections in the
tail docstring (they are in the docs anyway).
Disabled warnings during tests.
Explicitly disabled tests execution on Python
v.2.2 . In addition to the slicing tests, other
ones are failing.
Removed code duplication between the
``__init__`` and the ``update`` methods.
Misc. cleanup.
Also, based on code from `Tim Wegener`_:
- added the ``rename`` method;
- removed a ``has_key`` usage in the
``__setitem__`` method.
Documentation
--
Moved the ISSUES chapter from code's tail
docstring to here.
Moved up the `Creating an Ordered Dictionary
http://www.voidspace.org.uk/python/odict.html#
creating-an-ordered-dictionary`_ chapter.
Added prompts to the code examples and removed
the superfluous print statements (sometimes
they were there, sometimes they were not).
Misc. cleanup.
.. [#] So either no-one is using it, or it's
really good...

Re: Several entries on Tile and TableList at the Tkinter wiki
Thanks for posting this entry, The fact that a wiki or help site doesn't get a lot of traffic is not an necessarily an indicator of it's usfulness. It indicates to me that the product, in this case Tkinter, may be easy to use and understand, after working with it a little, A lot of help may not be necessary. A good example is the py2exe help site. At one time not to long ago there might be 8 to 12 post per day, or more. Today by my unscientific count method, I don't think there are more than 3 to 4 post per week. Yet, py2exe and Tkinter is almost as valuable as Python. If we couldn't build programs for Windows, where would a python programmes's money come from?

I've noted a serious lack of resources/documentation about these two powerful Tk components. In addition to some documentation, screenshots, and sample applications, I've posted updated versions of the original TableList and Tile wrappers by Martin Franklin. I should take this moment to thank Mr. Franklin for his work on these wrappers; whatever I added to them was pretty minimal compared to the heavy lifting he did. He originally posted them on the Internet last year, but the site that hosted them has gone dark. Anyway, Mr. Franklin, if you are reading this, thank you for your hard work; it has been enormously helpful. I hope my own efforts extend your work and make it even more useful for other Tkinter developers.

Re: Access to variable from external imported module
The TRS-80 I bought came with both Basic and Assembly Language teaching guides, and that was it. To make the machine work one had to program. I didn't mean to imply that Bill Gates developed it. It's well known that MS borrowed stuff when they needed to from where ever the could get it. That's business. I'm not an MS fan but Bill Gates was the one who gave away a very cheep, borrowed but improved, copy of DOS to computer sellers. These copies could also be copied to floppies (8 inch). So, DOS 3.3 was used by computer sellers, to install DOS on the buyers machine, (intel 286) free. On the other hand, IBM sold the same package for $50.00. I got the free copy of MS 3.3 with my 286. After that, Windows 3.0 cost me $25.00, Windows 3.1 cost me $30.00, DOS upgrade from3.3 to 6.22 cost me $55.00. Since then I purchased Win 95, $100.00 and Win 98. $125.00. And, all for testing software that I produced for people that use that stuff. Bill Gates probably can't program any software to write Hello World on any screen, but I'll bet he knows how to fill out a deposit ticket. I think Bill Gates recognize early that the money is in the marketing of the product, not the programming of it.

Think about relating a Tkinter variable to each

others.) Then you will have to keep the variables

As I understand the lambda syntax, what this

I haven't been able to figure out py2exe setup script yet, so I can't compare them. Hope this helps, Rooy -- http://mail.python.org/mailman/listinfo/python-list
Re: Tkinter check box behaviour - Windows / Linux discrepancy
Peter,
You already have an answer to you question but if
you want to fancy up your program you could
replace;
self.chkTest.bind('ButtonRelease-1',
self.chkTest_click)
with
self.chkTest.bind('f2',self.chkTest_click0)
or some other acceptable key from the keyboard
def chkTest_click0(self,event):
self.chkTest_click()
def chkTest_click(self):
# read check box state and display
appropriate text
if self.intTest.get()==0:
self.lblTest.config(text='Check box
cleared')
else:
self.lblTest.config(text='Check box
set')

I've come across a weird difference between the
behaviour of the Tkinter checkbox in Windows

code I wrote to display an image in a fixed
size canvas widget. If a checkbox was set then
the image should be shrunk as necessary to fit
the canvas while if cleared it should appear
full size with scrollbars if necessary.
The code worked fine under Linux (where it was
developed). But under Windows, the first click
in the checkbox did nothing, then subsequent
clicks adjusted the size according to the
PREVIOUS, not the current, checkbox state.
I've isolated the problem in the code below,
which shows a single checkbox and a label to
describe its state. It works ok under Linux,
but in Windows it is always one click behind.
Any ideas? I am using
Linux: Fedora Core 3, Python 2.3.4
Windows: Windows NT, Python 2.3.4

Re: Simple Tkinter problem
Greg, Run the following code to see how pack_forget() or grid_forget() works, it makes previous widgets disappear but not go away. If you call grid() or pack() again after using grid_forget() the widget returns. root = Tk() class Ktest: def __init__(self): self.Ftest1() def Ftest1(self): try: self.test2.grid_forget() except AttributeError : pass self.test1 = Button(root, text='Push #1 button', bg = 'yellow', width = 25, command = self.Ftest2, height = 25) self.test1.grid(row=0, column=0) def Ftest2(self): self.test1.grid_forget() self.test2 = Button(root, text='Push #2 button', bg = 'green', width = 15, command = self.Ftest1, height = 10) self.test2.grid(row=0, column=0) if __name__== '__main__' : Ktest() mainloop() Maybe someone else has an idea about not defining a variable. My question is how does a budket of wires and screws know its a bucket of wires and screws unless someone tells it that it's a bucket of wires and screws?

My problem is that each widget also contains the previous widgets when they pop up. How do I reinitialize the widget each time so that it doesn't contain earlier ones? Actually, another question I have is, is there a way to set python so that it will assume any undefined variable is 0 or ''? That is, I have several statements like If k 0 then so and so and I would like it to assume k=0 unless I tell it otherwise. I've just been defining k=0 at the start of the program but it seems there should be a better way. Greg -- http://mail.python.org/mailman/listinfo/python-list
