Computer locks up when running valid stand alone Tkinter file.
py help,
The file below will run as a stand alone file.
It works fine as it is.
But, when I call it from another module it locks
my computer, The off switch is the only
salvation.
This module when run as a stand alone, it will
open a jpeg image and add a vertical and
horizontal scrollbar to the canvass.
That's all it does.
Replace the img9.jpg file with one of your own,
put the image in the current working dir., and
run.
If you think you can help, I would appreciate it.

The character '\' is an escape character. It won't
show just like '\n' at the end of a line doesn't
show.
To show it must be preceeded by another '\' like
this '\\'
figgure out a way to start with '\\' and you'll be
ok.
x = str.split('\\xc5\\xeb\\xc7\\xd5\\xbc', '\\')
print x, '## x on line 10 == \n\n\n'
### '\n' won't show on printed line
print x, '## x on line 15 == \\n'
### '\n' will show on printed line
for n in x:
n= '\\'+n
print n

Re: Computer locks up when running valid stand alone Tkinter file.
Thanks for responding,
For those who care.
The solution to the problem was;
First, I did not give a parent to the Yview
scrollbar.
Next, I used the pack geometry for this class and
everything else is grid geometry.
When run stand alone it ran fine because the Yview
scrollbar attached itself to the default parent,
but when run from another module, it locked up.
The difficulty is really in the fact that
scrollbar Yview without a parent tried to attach
itself to the root Tk, already built and running
with grid geometry.
Pack and grid in the same Frame don't get along
(computer lockup).
Give Yview a parent, problem solved.
Changed pack to grid anyway.

Try something like this.
for eachline in data1:

for line in data::
print line
You might also think about a while loop.

How about something like one of these;
if os.path.isfile(vfileName) not True :
male file
or
if os.path.isfile (os.path.join(os.getcwd(),

Part of the mission of the Cheese Shop is to safeguard the name of your software. Once registered, no one else can use that name. That's been done, unless you spelled the package name wrong. I read the following, and I'm not sure if you have tried it. The quote below is from: http//:www.python.org/doc/current/dist/package-index.htm item #7 Registering with the Package Index. (11-15-2004) "By default PyPi will list all versions of a given package. To hide certain versions, the hidden property should be set to yes. This must be edited through the web interface." Sounds to me that you can hide what is on the site and submit a new version, if you set "Hidden property" to "yes". I don't know of any other place to register a python package with the python organization. Good Luck, jim-on-linux http://www.inqvista.com -- http://mail.python.org/mailman/listinfo/python-list

I suggest that the Cheese Shop also forward copies of help request to a site like this or similar. At least the sender knows that someone will read the email and help is on the way. Also, my guess is that before these postings of the last few days, 65% of the people on this site never heard of The Cheese Shop, Postings like these can only help The Cheese Shops. jim-on-linux http://www.inqvista.com > > Remember that python.org is run by volunteers, > but they are mostly highly capable volunteers. > This is probably just a change situation that > wasn't anticipated in the design (we all make > mistakes). > > A simple change of email address could probably > be achieved by tweaking the data for one or two > individuals, and an automated solution should > clearly be added as volumes build up. > > For now, how about a link that causes someone > to receive email?

My previous post was hasty and we all know, "Haste makes waste." Try this; If you use wiget-01.pack_forget() or wiget-01.grid_forget(), you can now build wiget-02 using wiget-02.pack or grid() for the same location. You can reinstall uninstalled wigets by using pack() or grid() again for those hidden wigets. However only after uninstalling for the wigets in those locations. root = Tk() test1 = Button(root, text='Test No.1 button', bg = 'yellow', width = 15, height = 10) test1.grid(row=0, column=0) test1.grid_forget() test2 = Button(root, text='Test #2 button', bg = 'green', width = 15, height = 10) test2.grid(row=0, column=0) mainloop() jim-on-linux http://www.inqvista.com -- http://mail.python.org/mailman/listinfo/python-list

Re: how do I pass values between classes?
Kath,
You can use this class to pass values around
without concern for conflicts since it has no
values of its own.
class Kvariable:
def setVariable(self, variable):
self.output = variable
def showVariable(self):
print self.output
x = Kvariable()
y = Kvariable()
x.setVariable("James_01")
y.setVariable("Kath_01")
x.showVariable()
y.showVariable()
x.setVariable('3.14159')
y.setVariable("python.org")
x.showVariable()
y.showVariable()

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.

Re: Press button to load data
Just from a glance my thoughts are to
start with one file and build on it. Make
a class of it so you can loop it to use
it over for each record.
You wrote that the info was in a file on
the hd. If it is in a file on the hd, use the
open()
function, read from the file, only one record
and write the data to a list.
You can incorporate the
button option,
"command = CallSomeFunction",
to call a function that builds a window,
and loads the data into labels or
entry boxes.
If you are going to modify
the data, entry boxes allow you to
modify it and save it back to a
file.
Also, when using the open() function,
close it after you get the data you need.
otherwise you may experience
unexpected problems.
client = open('client', 'r')
client.read() (readline()) (readlines())
client.close()

Think about relating a Tkinter variable to each
button then the button is related to a unique
variable. ( Tkinter StingVar or IntVar or some
others.) Then you will have to keep the variables
in a list or dictionary for recalling.

put this at the top of your code. After the window

I didn't run the code, and it has it has a coding error but if removed, the results should be; searchterm = 'help' self.searchterm = 'help' Kdo.searchterm = 'help' Sound silly but many people have trouble with getting a variable from here to there in their code.

Would it be better for me to write, your question above was Is that a typo? Or is it better if I were to write, your question above, "Is that a typo?", is a legimate question, but not clear. So, to be clear one might write is "Kdoi" correct?. A clear response would be, it is not "Kdoi", it is "Kdo". But that's not correct either, it is Kdo. If one runs the code I don't expect the user to look for "help", I think we will see help and will THINK that the results are correct.

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. How else can you explain the success of Windows, like it or not? jim-on-linux http://www.inqvista.com On Friday 24 November 2006 17:18, Dennis Lee Bieber wrote: > On Fri, 24 Nov 2006 16:56:58 -0500, > jim-on-linux <[EMAIL PROTECTED]> > > declaimed the following in comp.lang.python: > > That was when bill gates just left Harvard, > > basic was brand new, and 4k of memory was > > Pardon?

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?

Re: writing serial port data to the gzip file
If someone hasn't already commented,
Aside from any other problems, the file you are
trying to write to is (opened)?? in the "w" mode.
Every time a file is opened in the 'w' mode,
everything in the file is deleted.
If you open a file in the 'a' mode, then
everything in the file is left untouched and the
new data is appended to the end of the file.
Your while loop is deleting everything in the file
on each loop with the 'w' mode.
try,
vfile = open('vfile', 'a')
rather than
vfile = open('vfile', 'w')

Easiest way to print from XP/DOS.
This is the situation I'm in.
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
screen which reads something like this;
Which program authorized this operation?
Since I don't have an xp machine, the statement
above may not be exact, but you get the idea.
The question I have is, first is there any way to
work around the question asked by the xp machine
using python.
If not, I may have to register the package in xp,
if registering the utility the only way, which
package is the simplest to use.
Also, if the utility is registered in xp, will the
same statement send the file to the printer as it
does in win98.

Re: Easiest way to print from XP/DOS.
Did you run from a file or type in from keyboard?
When the client runs the utility program the
output file is built but nothing prints and no
messages appear. When I typed from keyboard on an
xp pro at c:\, I got the message.
Is it possible that virus detector or some
self.defense software is interacting?

Re: Easiest way to print from XP/DOS.
Thanks, The client is in a one printer office. If the output file is opened with note and then sent to the printer everything is fine but it defeats the purpose of the utility. Also tried > lpt1 but the same results. I'm trying to find out if this was some change in xp from previous versions, or is there something abnormal going on.

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. The idea of the utility is to eliminate the operator. But, if you have a virus detector that stops the operation then I think I may have to install the program as opposed to unzipping and running the exe file.

what version of py2exe are you using?
I had a similar problem with an old version of
py2exe but it it is fixed now. If my memory is
correct I had to import dbhash into my setup for
py2exe back then to fix it..
Your code for shelve is correct, the problem is
someplace else.

Right, the data is there.
My question is framed wrong. Your answer pointed
out the flaw in the question.
Since I'm on linux, the database can be opened
with Knoda. Once opened the table collumns are
always 10 spaces so all the data is not readable
as presented. Not quite a python problem.
I can Tk a display for the data, just thought I
could save time by letting the user open the
table and read the data right from the table.
Thanks for the help.

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.
I've tried
cursor.execute("select * from debtor where key
is not null ")
The table debtor does not exist so I get
"OperationalError"
which I want to trap with try/except or some other
way.
However python 2.5,
except OperationalError:
responds with
"OperationalError" is not defined.
Ideas on how to determine if a table exists would
be welcome.

SQLite3, data not found
Python help,
I just started working with SQLite3 and ran into
this problem.
Below, the first select produces results but,
after closing then re-opening the database the
select produces an empty list. Anyone know the
reason ??
The table seems to be empty.
import sqlite3
con = sqlite3.connect('myData')
cursor = con.cursor()
cursor.execute ("""create table data
(recordNo varchar,
caseNo varchar)""");
record = ['A', 'B']
cursor.execute("insert into data values (?,?)",
record ) ;
cursor.execute("select * from data ");
print cursor.fetchall();
con.close()
con = sqlite3.connect('myData')
cursor = con.cursor()
cursor.execute("select * from data");
print cursor.fetchall();

I have been getting the same thing using SQLite3
when extracting data fron an SQLite3 database. I
take the database info which is in a list and do
name = str.record[0]
rather than
name = record[0]
So far, I havn't had any problems.
For some reason the unicode u is removed.
I havn't wanted to spend the time to figure out
why.

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.

Re: can't find a way to display and print pdf through python.
I'm using Suse Linux which has five program that
will open a pdf file from a shell command line.
Acrobat Reader is one of the five.
A right button click on the file should give a
list of programs that will open a PDF file.
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
any of the exec.. args, or the popen, spawn, or
system modules.
os.execvep() ## or others like execl, execle
os.spawnv(),
os.spawnve(),
os.popen()
hope this give some direction.

If you live on latitude 40 and longitiude 32 I can
find that location.
Your mouse is pointing to x, and y, which is

For those who care, the file below should run on a unix/ linux style system.

window opens with os.system()
python help,
I'm testing on xpPro
I have a simple module that sends text files to a
printer. Then, it moves the file to the 'Fprtd'
directory. The module contains the following
code;
#
for n in PrtList:
os.system('type '+n+ ' > prn'
os.system('move '+n+ ' Fprtd')
#
os.system opens and closes a window for each file
it sends to the printer and again for each time
it moves a file to the Fprtd directory. If there
were only a few files, this wouldn't be so bad.
But, when the files number 300 to 400 it becomes
objectionable.
Is there any way to supress the flashing window.
xp no longer allows the 'ctty' command.

Sounds to me that you want a navigation window for a chosen image. Gimp imaging program has such a window. Check out how gimp works with multiple images. You might want to work with a toolbar that opens a navigation window for each image. For an explanation on how scrolling works check out a book by O'Reilly written by Mark Lutz, Programming Python, look up programming scrollbars. jim-on-linux http://www.inqvista.com -- http://mail.python.org/mailman/listinfo/python-list

Bug fix excluded,
After unpacking the compressed version of Python, look for a file
named "README".
Open "README" and look for Installing. Make install and Make
altinstall is explained.
I don't like to read instructions but in the long run, it saves time.

This works for me.
I converted your numbers to text,
I believe shelves requires string keys and
values.
I had to eliminate the import Person, Manager

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.

class Quitter (Frame):
# subclass our GUI
def __init__(self, parent=None):

Frame.__init__(self, parent)
self.pack()
widget = Button(self, text='Quit',
command=self.quit)
widget.pack(side=LEFT)
def quit(self):
ans = askokcancel('Verify exit',
"Really quit?")
if ans: Frame.quit(self)
if __name__ == '__main__':
Quitter().mainloop()

try this;
("update items set contents = (?) where id
=(?)", [ x, y] )
put your data in a list
or
("update items set contents = (?) where id
=%d ", [ x] )
below statement "uses 1" refers to the one
(?) , 0 supplied, means no list or none in
list.

python program deleted
py users, I developed a python program and used py2exe to create the exe. I zip the entire package and email it to my clients. Some clients get the zip file, unzip the package and everything works fine. And some clients get my email with an icon attached which has the correct filename but the size is 8k when it should be about 5 mb. I've renamed the file without the zip ext. and tried other renaming schemes without success. Has anyone had this experience? Any ideas on how to solve this problem. jim-on-linux -- http://mail.python.org/mailman/listinfo/python-list
