How to execute a script from another script and other script does not do busy wait.
I want to run a python script( aka script2) from another python script (aka script1). While script1 executes script2 it waits for script2 to complete and in doing so it also does some other useful work.(does not do a busy wait). My intention is to update a third party through script1 that script2 is going to take longer. Please suggest how should I go about implementing it. I'm currently executing it as: import main from script2 ret_code = main() return ret_code which surely is not going to achieve me what I intend. Thanks, Rajat. -- http://mail.python.org/mailman/listinfo/python-list

I've single CPU machine. I've a feeling that the thread created, which would run script2, would eat up all of the CPU if I do not use sleep() in script2. That way, script1 would still be waiting for script2 to finish. Thus, my program is no way different from the sample program I posted earlier. Is there any other way out? -- http://mail.python.org/mailman/listinfo/python-list
thread return code
Hi, I'm using threading module in Python 2.6.4. I'm using thread's join() method. On the new thread I'm running a function which returns a code at the end. Is there a way I access that code in the parent thread after thread finishes? Simply, does join() could get me that code? Regards, Rajat -- http://mail.python.org/mailman/listinfo/python-list
Thread get off from CPU occasionally. I suspect.
Hi,
I'm using Python 2.6 and using the threading module.
In a python module (parent module) I'm importing main() function from
another python module. I'm runnin this main() function on a Python
thread so that I can periodically check in the parent thread/module if
the new thread is up and running. This information that the python
script running on the new thread is still up and running is passed to
a 3rd party application (in a manner known to 3rd party).
As 3rd party is waiting for this new thread to finish. It waits for 3
mins and on told to it by the parent thread that new thread is still
running, the 3rd party then starts to wait again for 3 mins.
I've successfully implemented this functionality and it runs well
except for a rare chance when the new thread does not completely runs.
However, most of the cases the new thread runs completely. I cannot
understand why and when the new thread gets off the CPU or crashes or
any other thing?
I'm not able to figure out what is happening.?
The code in the parent thread that starts the new thread is as
follows?
exec("from " + passed_script_file + " import main") #imported main
function. It works.
import threading
import time
p = RunTestScript(main)
p.start()
t_nought = time.time()
logSystemInfo(t_nought)
seconds_passed = 0
keep_alive_set = 0
while p.isAlive() == True:
p.join(60.0)
if p.isAlive() == True:
seconds_passed = time.time() - t_nought
if seconds_passed >= 120:
t_nought = time.time()
if keep_alive_set != 1:# 3rd party way of informing
that the new thread is alive.
request = 'SET SHARED VAR KEEP_ALIVE=%d' %(1)
res = handle.submit('local', 'VAR', request)
if (res.rc != 0):
logSystemError('[PyInt] Error: STAF local VAR %s
failed, RC: %s, Result: %s\n' % (request, res.rc,
res.result))
return res.rc
keep_alive_set = 1
Earlier, when I did not run the main function on a new thread, it
always used to run completely. I used to run it as:
exec("from " + passed_script_file + " import main")
retCode = main()
Thanks and regards,
Rajat

Accessing windows structures through ctypes.

Thanks Alex. As you suggested, I'm trying to implemenet the below
structure, windows PEB, in Python:
typedef struct _PEB {
BYTE Reserved1[2];
BYTE BeingDebugged;
BYTE Reserved2[21];
PPEB_LDR_DATA LoaderData;
PRTL_USER_PROCESS_PARAMETERS ProcessParameters;
BYTE Reserved3[520];
PPS_POST_PROCESS_INIT_ROUTINE PostProcessInitRoutine;
BYTE Reserved4[136];
ULONG SessionId;
} PEB;
My equivalent Python structure is:
class PEB(Structure):
_fields_ = [("Reserved1", wintypes.BYTE * 2),
("BeingDebugged", wintypes.BYTE),
("Reserved2", wintypes.BYTE * 2),
("Reserved3", c_void_p),
("Ldr", pointer(PEB_LDR_DATA)),
("ProcessParameters", pointer
(RTL_USER_PROCESS_PARAMETERS)),
("Reserved4", wintypes.BYTE * 104),
("Reserved5", c_void_p),
(),
("Reserved6", wintypes.BYTE),
("Reserved7", c_void_p),
("SessionId", c_ulong)]
I'm not sure what needs to go in the above empty tuple for
"PPS_POST_PROCESS_INIT_ROUTINE PostProcessInitRoutine" (in Original
PEB).
Please suggest.

My OS is a windows XP sp3. All I'm trying to achieve is to close an application ( which could be a notepad, a wordpad or some other text editor) that have opened my file. Once the file is closed I can easily delete that file. I guess, if file is opened by one of that application, the file must be locked and so is the reason I cannot delete the file.

How do I organize my Python application code?
Hi, I'm learning Python to write a GUI application using Tkinter & Tk. I've evaluated Eclipse and Pydev. With the help of Fabio Zadrozny I successfully installed Eclipse and PyDev. Thanks. Now, I'm learning Eclipse and PyDev. And my problem is that I don't have an understanding of how the code in Python is generally organized, in case my code spans multiple files, modules, etc. I've been using C/C++ althrough my life on Linux and Visaul Studio, so the way their code is organized in a group of header files, source files, etc, I'm looking for a similar way in Python way or an approach to organize my python GUI application code? I'll be using Eclipse and PyDev as my development tools. So, please suggest from these tools prespective.

ActiveState Python v2.5 doesn't come with Tkinter or Tk installed.
Hi, So, now I've finally started using Eclipse and PyDev as an IDE for my GUI Application. I just wrote some sample programs as an hands on. Now I would like to take up Tkinter. I'm using Active State Python version 2.5 and found that there is not Tkinter and Tk module in it. To use Tkinter do I actually require Tk installed on my machine? Please suggest and where can I find both these modules? Also, please direct me to a good and short document on using Tkinter or Tk in Python.

Windows / Tkinter - problem with grid - not able to place widgets at desired places
Hi,
I'm learning Python and Tkinter. I've started programming in Eclipse with PyDev.
I'm intending to create a GUI. I'm not able to understand the Grid
manager perhaps because there is quite a less documentation available
for it on the net.
My desired GUI is attached in the mail. Although I've tried writing a
class module for this GUI but I'm not able to set all things right in
the GUI. The Biggest problem seems to be with the Grid Manager in
terms how it divides a window in Rows / columns. etc. I'm not able to
place none of the widgets correctly in the GUI.
For your convenience, I'm attaching this code also as myModule1.py .
Please some one review it and help create me this GUI.
PS: The desired GUI is attached as a GIF file. The version v1.4.5.1 is
a label the contents of which are dynamically picked.
Thanks and regards,
Rajat

WindowsXP / CTypes Module - unable to access function in a dll
Hi, I'm using the CTYPES module of python to load a dll. My dll contains a Get_Version function as: long __stdcall af1xEvdoRDll_GetVersion(long version[4]); This function accepts a long array of 4 elements. Following is the python code I've written: from ctypes import * abc = windll.af1xEvdoRDll GetVersion = abc.af1xEvdoRDll_GetVersion print GetVersion versionArr = c_long * 4#array of 4 longs version = versionArr(0, 0, 0, 0) # initializing all elements to 0 GetVersion(version)#calling dll function print version I'm getting the following output: <_FuncPtr object at 0x00A1EB70> <__main__.c_long_Array_4 object at 0x00A86300> But I'm not getting the desired output which I expect as : 2.1.5.0 Please suggest what am I missig? -- http://mail.python.org/mailman/listinfo/python-list

The code in fact is correct and I got the right answers. It is just that I was not priting results in a right manner. I added : print i in version : print i this solved my problem.

WindowsXP/ CTypes - How to convert ctypes array to a string?
Hi, I've used CTYPES module to access a function from a dll. This function provides me the version of the dll. This information is accessible to me as an array of 4 long inetegers. information as : 2, 1, 5, 0 I want to display these elements concatenated as "v2.1.5.0". This string ( I'm thinking of writing the above 4 array elements to a string) is to be displayed as label in a GUI ( the GUI used is Tk) Please suggest how can I write these elements to a string to get me the desired results as "v2.1.5.0". And, is writing to a string is right way? PS: this string also needs to be displayed in the GUI label well. FYI, the code written to access function from dll is as under: from ctypes import * abc = windll.af1xEvdoRDll GetVersion = abc.af1xEvdoRDll_GetVersion print GetVersion versionArr = c_long * 4 version = versionArr(0, 0, 0, 0) GetVersion(version) print version for i in version: print i * Results are : 2, 1, 5, 0 Cheers, Rajat -- http://mail.python.org/mailman/listinfo/python-list

I read all the replies. In fact I'm thankful to you all guys who are responding so quickly to all questions. I also add the letter 'v' same as you suggested. However, I'm looking to store this into some variable ( that variable could be be a string, tuple or anything, Im not sure which is the suited one) so that I can access it in some other module that will then display this version information in a Label Widet in GUI. So, what is the best way to store 'v1.2.3.4' in a variable? And, what type of variable is most suited (so as able to be used in other module probably, as string there)?

Tkinter tkMessageBox problem - message box is displayed with an additional window
Hi,
I'm working on Windows Platform
I'm facing some problem with the tkMessageBox. My code is as below:
import tkMessageBox
import Tix
from Tkinter import *
if len(installedLibPath) != len(listOfLibraries):
if tkMessageBox.askyesno("Question", \
type='yesno', icon='warning', \
message="Some of the libraries are
not installed. Do you wish to continue with the remaining?"):
myRoot = Tix.Tk()
myAppGUIObject = myAppGUI(myRoot)#Class for my GUI
myRoot.mainloop()
else:
sys.exit(0)
The Message Box is called before the Tix.Tk mainloop(). The problems
are as under :
1. Since the message box is displayed before the mainloop() is
started, the message box is displayed with another window that is
blank. This should not be displayed.
2. As a results of this messagebox (called before the mainloop) the
original Gui started by mainloop doesnot work as desired. Some of the
checkbuttons are displayed as unset (i.e un-ticked). These
checkbuttons used to be set at initialization before I stared using

How to check is something is a list or a dictionary or a string?
Hi, How to check if something is a list or a dictionary or just a string? Eg: for item in self.__libVerDict.itervalues(): self.cbAnalysisLibVersion(END, item) where __libVerDict is a dictionary that holds values as strings or lists. So now, when I iterate this dictionary I want to check whether the item is a list or just a string? Thanks, Rajat -- http://mail.python.org/mailman/listinfo/python-list

Thanks for the suggestions.
I wondered if the item is really a string. So I added the following to
check this:
item = ""
for item in dirList:
print type(item)
if item.endswith('\\'):
item = item[:-1]
dirListFinal.append(item)
Though item.endswith() is not workin still. The type of item is
appearing to be
So this confirms this is a string. But why the string operation
endswith() is not working.
Really strange.

There is just a single \ at the end of every item. My list is as below:
['Results v1.0/', 'Results v1.1/']
so,
if x.endswith('\\'):
is that correct?

How to delete elements from Tix Combo Box?
HI, I'm using a Tix combo box (I call it combo2), the contents of which are loaded depeding on the selection in another Tix combo box(I call it combo1) I have used the commands: self.cbAnalysisLibVersion.insert(END, results) to insert elements to the combo box. I'm looking for some similar option to delete elements from the combo box. I mean, as soon as I change selection in combo1 the previous elements in the combo2 should get cleared up( or deleted) and | shall be able to the above insert command to add new elements to the combo2 ( depending upon selection in combo1) Please suggest how can I clear up the ( delete the entries) in combo2.

Fredrik, Thanks so much. That worked.
Following this, I can now see that my combo2 has no previous elements
and contains only the elements relevant to selection in combo1.
Now, as soon as I select something in combo 2 and go back to change
selection in combo1 the combo2 must get its history cleared up (i.e
the previous selection in combo2's entry subwidget)
I used the command before I delete the entires :
self.combo2.config(history = False)
But this does not seem to be working;
Here is my code snippet:
Inside the callback function of combo1:
for libName, libResults in self.__libVerDict.items():
if libName == selectedLibName:
#Get the list of labelled results
resultsVer = self.__libVerDict[libName]
self.combo2.config(state = NORMAL)
self.combo2.config(history = False)
#Delete the previous entries from the listbox
#subwidget of combo box
subLB = self.combo2.subwidget("listbox")
subLB.delete(0, END)
#Add the results to the combo box
for results in resultsVer:
self.combo2.insert(END, results)

What is module initialization?
Hi, I found on the net that there is something called module initialization. Unfortunately, there is not much information for this. However, small the information I found module initialization can be of use to me in my project. I'm currently messing with a problem where I'm keeping my global variables ( or symbols) in a module and the other mdoules in the project acess these global variables. However, there is one case when a module updates one such global variable but the variable is not getting updated in the module containing global symbols ( variables). This happen only at the start of the program and at rest of the places in the program that global variable is not accessed. So, I thought of using this module initialization where I will intialize the module only once to update that variable. Ans in the rest of the program where ever this module is imported I shall be able to easily access the update value of the variable. Could some one provide me a sample code of module intialization? And how can I ensure that module initialization is done only once? Thanks and regards, Rajat -- http://mail.python.org/mailman/listinfo/python-list

Hi Diez,
Thanks for the information.
That's valuable information.
I though of displayin an information message on the screen through
tkMessageBox while the subprocess is running, I did it using:
try:
testing = subprocess.Popen([batchFilePath], \
shell = True)
retCode = testing.wait()
tkMessageBox._show("Test Harness execution", \
icon = 'info', \
message="Testing %s in progress..." % libName)
except:
tkMessageBox._show("Error", \
type='ok', icon='error', \
message="Error executing %s Test
Harness" % libName)
return None
else:
print retCode
But the message is never displayed. Please suggest if there is
something wrong with this code

Hi Aaquil,
Thanks for helping me out with this piece of information.
My Original code is :
testing = subprocess.Popen([batchFilePath], \
shell = True, \
stdout = subprocess.PIPE, \
stderr = subprocess.PIPE)
result = testing.wait()
if result < 0:
childError = testing.stderr.read()
tkMessageBox._show("Error", \
icon='error', \
message ="Error: %s" % childError)
return None
else:
print result
My child process was unresponsive. Later I got to know with the below code
that there were some errors coming from the child process which I was not
able to detect with this code.
I googled for some solution and found the below code :-
print "ttt", batchFilePath
#print os.listdir(batchFilePath)
try:
cmd = subprocess.Popen([batchFilePath], \
shell = True, \
stdin = subprocess.PIPE,
stdout = subprocess.PIPE, \
stderr = subprocess.PIPE \
)
cmd.stdin.close()
outPipe, errPipe = PipeThread(cmd.stdout), PipeThread(cmd.stderr)
outPipe.run(), errPipe.run()
retcode = cmd.wait()
out, err = outPipe.getOutput(), errPipe.getOutput()
if retcode != 0 and err != '':
raise ExecutionFailed, os.path.basename(batchFilePath) + "
exited with error code " + str(retcode) + " and errors:\n" + err
elif retcode != 0:
raise ExecutionFailed, os.path.basename(batchFilePath) + "
exited with error code " + str(retcode) + " and output:\n" + out
elif err != '':
return out + "\n" + os.path.basename(batchFilePath) + " gave
warnings:\n" + err
else:
return out
except Exception, e:
if isinstance(e, ExecutionFailed):
raise
else:
raise ExecutionFailed, "Error while executing " + ":\n" +
str(e)
Here are the Exception and the PipeThread Classes:
class PipeThread(threading.Thread):
def __init__(self, fin):
self.fin = fin
self.sout = ""
threading.Thread.__init__(self)
def run(self):
self.sout = self.fin.read()
def getOutput(self):
return self.sout
class ExecutionFailed(Exception):
def __init__(self, value):
self.parameter = value
def __str__(self):
return str(self.parameter)
Although, this solved my problem. But I know there is no need for using
threading in this problem. This problem could've been solved just by the
subprocess module.
I'm unnecessarily using the threading module.

Looking for a Duo - file comparison and a file parser
HI, I'm thinking of writing a file comparison utility in python. This utility will work as: 1. Compare 2 files for the differences. Both files contain some numerical results. 2. Generate a common file containing the differences (the same way as 'diff' generate an output) 3. Now, I will parse this file containing differences to check as to how much is the difference of one file from other. So, for this I hope a parser will be required. Is there a utility available that performs similar job ( that some one might have created considering the huge number of users of python) ? Or may be some one has written some parser? Any help is greatly appreciated. Thanks and regards, Rajat -- http://mail.python.org/mailman/listinfo/python-list

Tkinter: Unable to update the text scroll
Hi,
I've a Tkinter application which has some widgets and a textbox with
scrollbar, I call it txtScroll.
The txtScroll is used to display the processing log that application is
doing. Well the problem is that the txtSxroll is not able to display the log
at the time some thing is processed. Rather, it displays the log after the
complete processing processing is done. Example:
In a function, I've the following lines:
def func():
print 'Testing & Result Comp'
TASymbols.objLogToGUI.outputText("Starting Test and Results
Comparison\n")
if selectedLib != TASymbols.strSelectAll:
# we do not pass it as a string instead we will pass it in a
#single element list
libKey = self.__findKey(self.__libDict, selectedLib)
The colored line should display the stuff at the time it appeared in the
code. But only displays this after the function func() has processed
completely.
PS : I'm not using any threading stuff here..
Please help me resolve this problem.
Regards,
Rajat

Regular expression help: unable to search ' # ' character in the file
Hi,
Can some help me with the regular expression. I'm looking to search #
character in my file?
My file has contents:
###
Hello World

length = 10
breadth = 20
height = 30
###
###
Hello World
###
length = 20
breadth = 30
height = 40
###
I used the following search :
import re
fd = open(file, 'r')
line = fd.readline
pat1 = re.compile("\#*")
while(line):
mat1 = pat1.search(line)
if mat1:
print line
line = fd.readline()
But the above prints the whole file instead of the hash lines only.
Please help

Unable to write % character to a file using writelines() method
Hi,
I'm using the writelines() method to write some lines to a text file. But
I'm unable to write the % character to the file using the following format:
fdTolFile.writelines("\n\tdiff Not in %s '%' range" %(toleranceInPer))
The second % does not get write to the file and Im getting errors. Please
suggest what additional information should I give to write the % character.
The errro Im getting is :
File "C:\Documents and
Settings\\TA-workspace\src\TestAndCompareResults.py", line 840, in
__parseDiffTextFile
fdTolFile.writelines("\n\tdiff in %s'%' range" %(toleranceInPer))

I've also tried this:
fdTolFile.writelines("\n\tdiff Not in %s \% range" %(toleranceInPer))
But still I get the same error

os.path.exists() function does not work for http paths
Hi,
I have used os.path.exists() many a times for any file system paths in local
system. But this does not seem to work for an Http path.
e.g:
To check is the Results folder exists at the following path, I do:
if not os.path.exists("http://subversion.myCom.com/Testing/Results";):
print 'Path does not exist'
This always prints the above print statements whether or not the Results
folder exists or not.
Is there any such function to check existence of files. / folder at Http
paths?

Hi,
The problem got solved. After finding for such a long time I got a snippet
at google and used the same in my code. It solved the problem.
Here is the complete code now:
class cLogToGUI:
def __init__(self, logObj, appGUI):
self.__logger = logObj
self.__logger.debug("Inside cLogToGUI::__init__")
appGuiFrame = appGUI.frame4
#hor. scroll bar
self.hsb = Scrollbar(appGuiFrame, orient = HORIZONTAL)
self.hsb.grid(row = 2,column = 0, sticky = E+W)
#vertical scroll bar
self.vsb = Scrollbar(appGuiFrame)
self.vsb.grid(row = 1,column = 2, sticky = N+S)
self.txtLogger = Text(appGuiFrame, \
height = 20,\
width = 100, \
state = DISABLED, \
xscrollcommand = self.hsb.set, \
yscrollcommand = self.vsb.set, \
wrap = NONE, \
font = ("courier",12))
#self.hsb.config(command = self.txtLogger.xview())
#self.vsb.config(command = self.txtLogger.yview())
self.hsb.config(command = self.__hsbScrollHandler)
self.vsb.config(command = self.__vsbScrollHandler)
self.txtLogger.bind("<>", self.outputText)
self.txtLogger.grid(row = 1)
self.txtLogger.tag_configure("error", foreground = "red")
self.txtLogger.tag_configure("warning", foreground = "orange")
self.txtLogger.tag_configure("success", foreground = "blue")
self.__logger.debug("return from cLogToGUI::__init__")
def outputText(self, event):
self.__logger.debug("Inside cLogToGUI::outputText()")
self.txtLogger.configure(state = NORMAL)
string = TASymbols.strScrolledTextLine
tag = TASymbols.strScrolledTextLineTag
if not string:
self.txtLogger.delete('1.0', END)
else:
self.txtLogger.insert(END, string, tag)
#self.txtLogger.focus()
self.txtLogger.see(END)
self.txtLogger.configure(state = DISABLED)
self.__logger.debug("return from cLogToGUI::outputText()")
def __hsbScrollHandler(self, *L):
op, howMany = L[0], L[1]
if op == "scroll":
units = L[2]
self.txtLogger.xview_scroll ( howMany, units )
elif op == "moveto":
self.txtLogger.xview_moveto ( howMany )
def __vsbScrollHandler(self, *L):

Tix Combo box problem - remains in editable mode only
Hi
I'm facing a problem with the tix combo box in a way that my combo box is
always in an editable mode after I have cleared subwidgets Entry and Listbox
from it.
My setup is like this :
CheckButton1 :
If this is unset, the combo box should get disabled, the entries in it
should get cleared ( entries are listbox and entry subwidgets) which in my
case they get cleared.
When this check box is set again, the combo box should get enabled, with no
entries in listbox and entry subwidgets ( which are reallly cleared in my
case.) But the combox box having being enabled is in editable mode despite
of setting it to un-editable mode.
The code is as follows:
#Combo Box
self.cbAnalysisLibVersion = Tix.ComboBox(self.frame1, \
dropdown = True, \
command=self.__cllbkAnalysisLibVer, \
editable=0, \
variable=verSelection,
options='listbox.height 8\
listbox.width 25 \
entry.width 30 \
entry.anchor w \
entry.padx 30', \
history = False)
#Check Button box
self.chBtResultsComparison = Checkbutton(self.frame2, \
text = "Results Comparison",
\
variable =
varResultsComparison, \
command =
self.__cllbkResultsComparison)
def __cllbkResultsComparison(self, Event = None):
subLB = self.cbAnalysisLibVersion.subwidget("listbox")
subEntry = self.cbAnalysisLibVersion.subwidget("entry")
if varResultsComparison.get() != 1:
#Disable Tolerance Text Box
self.txtTolerance.delete(1.0, END)
self.txtTolerance.config(state = DISABLED, \
bg = "grey")
#Delete all entries (entry & subwidget's entries)
#in Reference Analysis Results Version Combo Box
#and disable this combo box.
#First Delete the Listbox sub-widget entries
subLB.delete(0, END)
subLB.config(state = DISABLED)
#Then delete Entry sub-widget entries
#subEntry = self.cbAnalysisLibVersion.subwidget("entry")
subEntry.config(state = NORMAL)
subEntry.delete(0, END)
subEntry.config(state = DISABLED)
self.cbAnalysisLibVersion.config(state = DISABLED)
#Diable Result Comparison Button
self.btViewComparisonResults.config(state = DISABLED)
else:
#Check box is ticked
#Enable the Tolerance text box
self.txtTolerance.config(state = NORMAL, \
bg = "white")
#Enable the Reference Analysis Combo box
#self.cbAnalysisLibVersion.config(state = NORMAL, editable=0)
self.cbAnalysisLibVersion.configure(state = NORMAL, editable = 0)
subLB.config(state = NORMAL)
subEntry.config(state = NORMAL)
self.btViewComparisonResults.config(state = NORMAL)
Please suggest what is that I am missing

Using Tkinter and Tix together opens a new DOS Window in addition to the actual GUI on windows XP
Hi,
I m using Tkinter and Tix. I'm using Tkinter mainly for all the widgets
except for the TixComboBox for which I use Tix.
My event loop starts like this:
myRoot = Tix.Tk()
myRoot.title("Test Automation")#
myAppGUIObject = myAppGUI(myRoot, logger) #myAPPGUI is the class for
creating GUI
myRoot.mainloop()
The problem is as soon as I doubel click on this script a DOS window opens
up in addition to the GUI.
I don't why is this happening? I assume the problem is becuase I'm using the
statement:
Tix.Tk()
when I'm using tix for only a combo box and the rest of the widgets are
tkinter widgets.
So,
1. Is the above approach fine?
2. How can I stop the dos window from opening up?

Tix: Windows XP: Problem - how to stop root window from popping up with Tix
Hi,
Im using Tix on widows XP and I've tried many ways to suppress the root
window. But so far I'm unable to do it.
Please suggest how can I suppress the root window.
My code is as follows:
import Tix
myRoot = Tix.Tk()
myRoot.withdraw()
myRoot.deiconify()
myRoot.title("Test Automation")
#Create GUI Object and pass the logger object
myAppGUIObject = myAppGUI(myRoot, logger) #My AppGUI class creates the GUI
which heavily uses the Tkinter widgets and only TixComboBox
myRoot.mainloop()
Please suggest if there is anything I'm missing.

Tkinter on WIndows XP opens a blank screen. How can I get rid of it?
Hi,
I m using Tkinter and Tix to create a GUI on Windows XP. So far I've created
the GUI and it just works.
But the problem is as soon as I double click on the script it besides
opening the GUI also opens a shell ( a blank screen) with it. Pleas suggest
how can I get rid of this blank screen.
My program is staring as :
myRoot = Tix.Tk()
myRoot.title("Test Automation")
< some stuff>
< ...>
myRoot.mainloop()
Thanks and regadrs,
Rajat

Ctypes behave differenty on windows 2000 and windows XP
Hi,
Im facing a strange problem with ctypes module on windows 2000. I did not
face this problem with the windows Xp.
The problem is this code and specifically "c_long" which behave differently
on win2000 and winxp
from ctypes import *
h = windll.LoadLibrary("C:\\Windows\\System32\\myDll.dll")
print h
ver = getattr(h, "myDll_GetVersion")
versionArr = c_long * 4
version = versionArr(0, 0, 0, 0)
print ver(version)
dllVersionStr = "v%d.%d.%d.%d" % tuple(version)
print dllVersionStr
The same code appears to work on windows xp with dllVersionStr printing as
v1.3.5.0
But on wIindows 2000 it prints v0.0.0.0
Please suggest why does it happen.
Thanks and regards,
Rajat

Login using usrllib2
Hi All,
I'm using urllib2 module to login to an https server. However I'm unable to
login as the password is not getting accepted.
Here is the code:
import urllib2, urllib
values={'Username': 'admin', 'Password': 'admin123'}
url='https://172.25.17.20:9443'
data = urllib.urlencode(values)
data = urllib.urlencode(values)
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
the_page = response.read()
print the_page
The error message I get in the_page output is the same as I get when I
access this site using a browser and supply a wrong password. It appears
password is not accepting.
I'm new to web programming. The aim is to automate user clicks on a web
server which can be replicated using python and http. Please suggest / help.
Regards,
Rajat

[Help] Python implmenentation of finding process's command line parameters.
I'm looking for some python implementation of finding the command line parameters of a process on Windows XP SP3 machine. I found some links but they all point me to the direction of c/c++ implememtations. I've seen WMI, but this takes time to load. So I just though if some one has done implementation and could pointing me in some right direction. Regards, Rajat -- http://mail.python.org/mailman/listinfo/python-list
Re: Python implmenentation of finding process's command line parameters.
I have had a look at psutil, however, this only works with Python 2.6.x and above. We are using Python 2.5.2 and updating python could pose certain problems. So, I'm not keep on using psutils. -- Regrads, Rajat -- http://mail.python.org/mailman/listinfo/python-list

Logging function calls without changing code
Hi Everyone,
Is there a way to log all function calls of a class without changing anything
in that class.
What I mean to say is if I have written a class previously and I want to enable
logging in that then I would probably need to write the following before my
function calls-
logger.debug(' called...')
But, is there a way that I do not need to change my existing code and can
create a wrapper around that existing class or something else which can help me
do the same?
Thanks.
