  • What are the differences among sqlite3 from python2.5, pysqlite and apsw

    - by leo
    Hi, I would like to know the differences among sqlite3 from python2.5, pysqlite and apsw? I have a bumpy run when trying to install pysqlite on windows vista with python2.5, see following: download sqlite from http://sqlite.org/download.html and unzip them into windows/system32 folder and put sqlite3.dll into c:/python25/Lib folder download pysqlite windows installer when trying to run following in python shell: >>> from pysqlite2 import test Traceback (most recent call last): File "<stdin>", line 1, in <module> File "pysqlite2\test\__init__.py", line 35, in <module> from pysqlite2.test import dbapi, types, userfunctions, factory, transactions,\ File "pysqlite2\test\dbapi.py", line 27, in <module> import pysqlite2.dbapi2 as sqlite File "pysqlite2\dbapi2.py", line 27, in <module> from pysqlite2._sqlite import * ImportError: No module named _sqlite I am wondering anybody with experiences of the above three types of sqlite binding to python can comment their pros and cons such as performances I am wondering is it worthwhile to try the pysqlite or apsw thanks

  • Cheetah pre-compiled template usage quesion

    - by leo
    For performance reason as suggested here, I am studying how to used the pr-compiled template. I edit hello.tmpl in template directory as #attr title = "This is my Template" \${title} Hello \${who}! then issued cheetah-compile.exe .\hello.tmpl and get the hello.py In another python file runner.py , i have !/usr/bin/env python from Cheetah.Template import Template from template import hello def myMethod(): tmpl = hello.hello(searchList=[{'who' : 'world'}]) results = tmpl.respond() print tmpl if name == 'main': myMethod() But the outcome is ${title} Hello ${who}! Debugging for a while, i found that inside hello.py def respond(self, trans=None): ## CHEETAH: main method generated for this template if (not trans and not self._CHEETAH__isBuffering and not callable(self.transaction)): trans = self.transaction # is None unless self.awake() was called if not trans: trans = DummyTransaction() it looks like the trans is None, so it goes to DummyTransaction, what did I miss here? Any suggestions to how to fix it?

  • Retrieve input entered in a JDialog

    - by Jules Olléon
    I extended JDialog to create a custom dialog where the user must fill some fields : How should I retrieve the data entered ? I came up with a solution that works. It mimics JOptionPane but the way I do it looks ugly to me because of the static fields involved... Here is roughly my code : public class FObjectDialog extends JDialog implements ActionListener { private static String name; private static String text; private JTextField fName; private JTextArea fText; private JButton bAdd; private JButton bCancel; private FObjectDialog(Frame parentFrame) { super(parentFrame,"Add an object",true); // build the whole dialog buildNewObjectDialog(); setVisible(true); } @Override public void actionPerformed(ActionEvent ae) { if(ae.getSource()==bAdd){ name=fName.getText(); text=fText.getText(); } else { name=null; text=null; } setVisible(false); dispose(); } public static String[] showCreateDialog(Frame parentFrame){ new FObjectDialog(parentFrame); String[] res={name,text}; if((name==null)||(text==null)) res=null; return res; } } As I said, that works properly, but I guess that might raise serious concurrency issues... Is there a cleaner way to do that ? How is it done in JOptionPane ?

  • How to disable Center Key (CK) and let only Left Soft Key (LSK) be used in j2me

    - by awaghad-ashish
    Hello everyone, I created a custom item in which I need to use the Center Key for the purpose of selecting and I am successfully able to use it with the keyPressed event using the keyCode as -5. The problem is, as soon as I press the CK, it also clicks on the command above the LSK and that causes the menu to pop up. Is there any way that I can disable the CK for a particular command or something like that (because I dont need CK, since I can click on the command through LSK as well, I want to use the CK specifically for the custom item)? Any kind of help will be appreciated, Thanks and regards, Ashish.

  • In WPF, What is the best way to create toolbar buttons so that the images are properly scaled?

    - by T.R.
    Specifically, I'm looking to use the 16*16 32-bit png images included with the VS2008ImageLibrary. I've tried manually setting the Height and Width attributes of the image, adjusting margins and padding, adjusting Stretch and RenderOptions. My attempts to create toolbar buttons have all led to either Improper Scaling (blurry icons), the bottom row of pixels on the icon being truncated, or the toolbar button being improperly sized - not to mention the disappearing icons already mentioned Here. Has anyone found the best way to make standard, VisualStudio/WinForms-style toolbar buttons that display properly in WPF?

  • How can I put all twill commands together into one piece of code in a .py file?

    - by brilliant
    Hello everybody! I have just started exploring TWILL. Twill is an amazing scripting language for Web browsing and it does all I want!!! So far I've been using twill from a Python shell (IDLE (Python GUI) to be precise) and I do things in the way of executing commands one by one (I mean, I type one command, run it, then type the next command): But I don't know how to put all these commands together in one .py file, so that they would all be executed one by one automatically. It seems that there is such possibility in twill. This example from the twill documentation page (you can see it HERE) shows us one piece of code consisting of several commands: So, my question is: How can I put all commands together in twill?

  • Compiling and installing pyactivemq on osx

    - by muanis
    I'm having a hardtime trying to install pyactivemq (link) on my osx leopard. Following a tutorial (in portuguese) on compiling it ends up ok, but when I run the tests i receive only a crypt message: "Fatal Python error: Interpreter not initialized (version mismatch?)" There is not much information on the web about using pyactivemq on osx, but what I could find is that is something related to wrong linking when boost compiles. I'm running: Mac OS 10.5.8 MacPorts 1.8.2 APR 1.3.9 Xcode 3.1.4 Boost 1.41.0 (installing for python 2.5) Activemq-cpp 2.2.6 pyactivemq 0.1.0 If someone has any info on this it would be helpful

  • How do I access session data in Jinja2 templates (Bottle framework on app engine)?

    - by TylerW
    Hello! I'm running the micro framework Bottle on Google App Engine. I'm using Jinja2 for my templates. And I'm using Beaker to handle the sessions. I'm still a pretty big Python newbie and am pretty stoked I got this far :) My question is how do I access the session data within the templates? I can get the session data no problem within the actual python code. And I could pass the session data each time I call a jinja template. But since I need the session data in the main menu bar of the site... that means I would have to pass it on every single page. Does anyone know if I can access it directly in the templates? For example I need the session data for my header links: Home | FAQ | Login or Home | FAQ | Logout Any help is greatly appreciated! :D

  • JSlider jump on mouse click

    - by Aly
    Hi, I have a JSlider which shows bet sizes (for a poker game) I am trying to achieve the effect that when a mouse click occurs the slider jumps forward by a bet amount (i.e. a big blind amount) rather than just incrementing by one. If the mouse click happens to the left of the bar i want it to decrement by a fixed amount else increment. I looked into attaching a mouse listener, but do not know how I can use the event to find out on what side of the bar the mouse was clicked. Any ideas?

  • Cannot connect QMainWindow and QDialog

    - by bartek
    Hi, I have a QMainWindow displaying a QDialog: CalibrationDialog d(this); d.exec(); My QMainWindow class has a signal: signals: void PenOn( QPoint p ); And QDialog has a slot: public slots: void on_PenON( QPoint p ); I tried connecting PenOn event to on_PenOn in two ways: After instantiating QDialog void MainWindow::on_actionC_triggered() { appState = CALIBR; CalibrationDialog d(this); connect( this, SIGNAL(PenOn(QPoint)), &d,SLOT(on_PenOn(QPoint)) ); d.exec(); } In QDialog constructor CalibrationDialog::CalibrationDialog(QWidget *parent) : QDialog(parent), ui(new Ui::CalibrationDialog) { ui-setupUi(this); [...] connect( parent, SIGNAL(PenOn(QPoint)), this,SLOT(on_PenOn(QPoint)) ); } None of this works :(. I'm emitting PenOn signal from MainWindow slot activated by another thread. What am I doing wrong?

  • How to fix weird scrolling/alignment behavior when using keyboard in MenuStrip?

    - by bentsai
    I started noticing strange behavior when navigating the main toolbar of my Winforms application, and I don't know how to fix it. When I initially open the dropdown of the File menu, it looks like this: I begin to scroll down each item with the arrow keys, and everything is fine until I reach "Exit". As soon as I hit the down arrow key from "Log Off", or if I hit the up arrow key from "Open", the menu rearranges itself to look like this: I'm puzzled by this behavior. The menu still works, and from this point, if I start scrolling up, I can get the arrangement back to normal: A few observations: The menu still works. This doesn't happen when using the mouse. I have some code that toggles the Visible property of some of the menu items. I was able to modify what the arrangement was by playing around with this, but it was still messed up. Can anyone help me understand what is going on, and how to fix it?

  • Creating a spider using Scrapy, Spider generation error.

    - by Nacari
    I just downloaded Scrapy (web crawler) on Windows 32 and have just created a new project folder using the "scrapy-ctl.py startproject dmoz" command in dos. I then proceeded to created the first spider using the command: scrapy-ctl.py genspider myspider myspdier-domain.com but it did not work and returns the error: Error running: scrapy-ctl.py genspider, Cannot find project settings module in python path: scrapy_settings. I know I have the path set right (to python26/scripts), but I am having difficulty figuring out what the problem is. I am new to both scrapy and python so there is a good possibility that I have failled to do something important. Also, I have been using eclipse with the Pydev plugin to edit the code if that might cause some problems.

  • Deploying a PyQt application on Windows Vista x64

    - by Skilldrick
    I'm working on an application for a client/friend using PyQt. I've been working on Linux and testing on Vista, but the target computer is Vista x64. Now, Python comes with compiled binaries of Python 2.6 for 64 bit Windows, but Riverbank don't provide 64 bit binaries for PyQt. I don't have much access to the target computer, so I can't really go through the hassle of compiling PyQt. This Google code project might be the solution, but I'm not sure if it's going to work. Can I use something like py2exe from 32 bit Vista, or would I have to have to make the executable from a 64 bit machine with PyQt 64 bit installed? Basically, am I going to have to compile PyQt on the target machine?

  • Correct way to get absolute url in django

    - by dreamiurg
    A problem that I stumbled upon recently, and, even though I solved it, I would like to hear your opinion of what correct/simple/adopted solution would be. I'm developing website using Django + python. When I run it on local machine with "python manage.py runserver", local address is http://127.0.0.1:8000/ by default. However, on production server my app has other url, with path - like "http://server.name/myproj/" I need to generate and use permanent urls. If I'm using {% url view params %}, I'm getting paths that are relative to / , since my urls.py contains this urlpatterns = patterns('', (r'^(\d+)?$', 'myproj.myapp.views.index'), (r'^img/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/img' }), (r'^css/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/css' }), ) So far, I see 2 solutions: modify urls.py, include '/myproj/' in case of production run use request.build_absolute_uri() for creating link in views.py or pass some variable with 'hostname:port/path' in templates Are there prettier ways to deal with this problem? Thank you.

  • Module import error using IDLE

    - by Nimbuz
    I'm an absolute beginner using IDLE (Python 2.6.4) to learn the basics. I recently found a Python program that I want to run but it throws an error although the code looks fine (i.e all modules exist): from css.parse import parse data = """ em { padding: 2px; margin: 1em; border-width: medium; border-style: dashed; line-height: 2.4em; } p { color: red; font-size: 12pt } p:first-letter { color: green; font-size: 200% } p:first-line { color: blue }""" for rule in parse(data): print rule for decl in parse(data)[0]: print decl Error: ImportError: No module named parse How do I fix this? I'm using Snow Leopard. Edit: I guess its a PATH issue, where should I place the modules, which directory?

  • ctypes and pointer manipulation

    - by Chris
    I am dealing with image buffers, and I want to be able to access data a few lines into my image for analysis with a c library. I have created my 8-bit pixel buffer in Python using create_string_buffer. Is there a way to get a pointer to a location within that buffer without re-creating a new buffer? My goal is to analyze and change data within that buffer in chunks, without having to do a lot of buffer creation and data copying. In this case, ultimately, the C library is doing all the manipulation of the buffer, so I don't actually have to change values within the buffer using Python. I just need to give my C function access to data within the buffer.

  • "Correct" way to playback user movement with xlib?

    - by Dasuraga
    I'm trying to figure out a way to make demos for a program I've written with xlib, and I came across this, but, according to the author page: This extension is not intended to support general journaling and playback of user actions. Does anyone know of any functions in xlib that are intended to support playback of user actions? Does it even exist? Or could I just use this without any real problems?

  • A very weird problem with texbox control in C# .net

    - by Kazoom
    Well i know textbox is a very simple user control, perhaps the first input control ever made. I have been facing a very frustrating problem with this simple control. I programatically add a textbox in my user control. From ui i am able to edit it like a normal textbox. however, i am not able to read the user inputed value in the program. my program all the time sees the old value with which my text box was initialized. i textchange event getting triggered but the value never gets updated. This seemingly looks to be some innocuous bug in the code, but the program is very simple and it does not seem to be having any bug. Any guidelines on this issue?

  • Install Bash completion together with distutils / pip

    - by ifischer
    I have created a simple Python module and want to distribute it with pip. I also want to install a Bash completion file together with the module. I'm installing the module with Python 2.7.1+ and pip 0.8.2. I have this setup.py: setup( name='jenkinsmon', version='0.0.1', description='Jenkins Job Monitor', long_description=open('README.txt').read(), scripts=['bin/jenkinsmon'], data_files=[ ('/etc/bash_completion.d', ['extras/jenkinsmon.completion']), ], install_requires = [ 'autojenkins', 'argparse' ], ) Now if I try to install the package with pip install -e ., the Bash completion file never gets installed together with the package. I also tried workarounds by specifying a MANIFEST.in, like described here: MANIFEST.in: include extras/jenkinsmon.completion But this also doesn't help - the completion files won't get installed. What can I do to install the Bash completion files?

    I have added android:windowSoftInputMode="stateAlwaysVisible" to my Activity in AndroidManifest.xml and here's my layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <EditText android:id="@+id/EditText01" android:layout_width="wrap_content" android:layout_height="wrap_content"></EditText> <EditText android:id="@+id/EditText02" android:layout_width="wrap_content" android:layout_height="wrap_content"></EditText> <Button android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Send"></Button> </LinearLayout> When the Activity starts, the EditText is focused, but soft keyboard isn't displayed. If I click on the EditText, then I see the soft keyboard. Do I need to set aditional parameters to display soft keyboard when my Activity starts? Thanks
