• How to install MySQLdb package? (ImportError: No module named setuptools)

  - by Verrtex

  Hi All, I am trying to install MySQLdb package. I found the source code here. I did the following: gunzip MySQL-python-1.2.3c1.tar.gz tar xvf MySQL-python-1.2.3c1.tar cd MySQL-python-1.2.3c1 python setup.py build As the result I got the following: Traceback (most recent call last): File "setup.py", line 5, in ? from setuptools import setup, Extension ImportError: No module named setuptools Does anybody knows how to solve this problem? By the way, if I am able to do the described step, I will need to do the following: sudo python setup.py install And I have no system-administrator-rights. Do I still have a chance to install MySQLdb? Thank you.

• Adding Existing Framework to Xcode (iPhone) error

  - by Urizen

  I have added the <QuartzCore/QuartzCore.h> to my Frameworks folder in my iPhone project and added the #import "<QuartzCore/QuartzCore.h>" statement at the top of a custom UIView class. However the custom UIView class gives me a "No such file or directory" compliation error in relation to the <QuartzCore/QuartzCore.h> framework. Is there something else I need to set so that the compiler can see the framework. I'm not expert on the Xcode IDE so any assistance would be extremely welcome.

• Exceptions and web services

  - by Schildmeijer

  Im using the standard java ws implementation shipped with e.g. java6 (javax.jws.*). I have the following: import javax.jws.*; @WebService(name="Widget") public interface Widget { @WebMethod public @WebResult String getGadget(@WebParam(name = "id") long id) throw MyOwnException; } Is this possible? Do I have to annotate MyOwnException with e.g the @WebFault annotation? During my initial tests I also noticed that, on the client side, the autogenerated MyOwnException was renamed to MyOwnException_Exception and wrapped the "original" MyOwnException. Or if this is a bad idea, are there any recommended Exceptions to throw from a webservice like this?

• Unable to load the Starteam Dump into SVN

  - by ssarivis

  Hi, I have a dump created from StarTeam 2008 R 2 (10.4.7.-64) using svn importer 1.1-M8. But when I am trying to import the dump its giving me error: * adding path : tags/Test/GH/13_Environment/Process/Capgemini EN Template - Business Case.doc ...svnadmin: File already exists: filesystem 'help\db', transaction '2-2', path 'tags/Test/GH/13_Environment/Process/Capgemini EN Template - Business Case.doc' I can see from the svn admin load o/p that the file has been added already. May be the dump created by SVN Importer is not correct. Can anyone guide me how to solve this ?

• Why is forControlEvents UNDEFINED?

  - by munchine

  Hi Guys, I've got a simple question but it has got me confounded. The code below gets a UNDEFINED error for UIControlTouchUpInside. What do I need to include or import? If I comment out the line, it works. So that means forState:UIControlStateNormal is defined. I'm new so hope you can help. UIButton * button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [button setTitle:@"Accept?" forState:UIControlStateNormal]; [button addTarget:self action:@selector(acceptTapped) forControlEvents:UIControlTouchUpInside]; button.frame = CGRectMake(225.0, 145.0, 80.0, 30.0); [self.view addSubview:button];

• sqL table is sorted by default

  - by Pramodtech

  I have simple SSIS package where I import data from flat file into sql table(MS sql 2005). File contains 70k rows and table has no primary key. Importing is sucessful but when I open sql table the order of rwos is different from the that of file. After observing closely I see that data in table is sorted by default by first column. Why this is happening? and how I can avoid default sort? Thanks.

• UIView Animation won't run transition

  - by dpelletier

  So, I've searched quite a bit for this and can't seem to find a solution. This code works: CGContextRef context = UIGraphicsGetCurrentContext(); [UIView beginAnimations:nil context:context]; [UIView setAnimationDuration:5]; [c setCenter:CGPointMake(200, 200)]; [UIView commitAnimations]; This code doesn't: CGContextRef context = UIGraphicsGetCurrentContext(); [UIView beginAnimations:nil context:context]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:c cache:YES]; [UIView setAnimationDuration:5]; [c exchangeSubviewAtIndex:0 withSubviewAtIndex:1]; [UIView commitAnimations]; And I know the call to exchangeSubViewAtIndex is working because if I remove it from the animation block it functions as expected. Anyone have any insight as to why this transition won't run? Something I need to import?

• How to preprocess a Django model field value before return?

  - by Satoru.Logic

  Hi, all. I have a Note model class like this: class Note(models.Model): author = models.ForeignKey(User, related_name='notes') content = NoteContentField(max_length=256) NoteContentField is a custom sub-class of CharField that override the to_python method in purpose of doing some twitter-text-conversion processing. class NoteContentField(models.CharField): __metaclass__ = models.SubfieldBase def to_python(self, value): value = super(NoteContentField, self).to_python(value) from ..utils import linkify return mark_safe(linkify(value)) However, this doesn't work. When I save a Note object like this: note = Note(author=request.use, content=form.cleaned_data['content']) The conversed value is saved into the database, which is not what I wanna see. Would you please tell me what's wrong with this? Thanks in advance.

• Unescape _xHHHH_ XML escape sequences using Python

  - by John Machin

  I'm using Python 2.x [not negotiable] to read XML documents [created by others] that allow the content of many elements to contain characters that are not valid XML characters by escaping them using the _xHHHH_ convention e.g. ASCII BEL aka U+0007 is represented by the 7-character sequence u"_x0007_". Neither the functionality that allows representation of any old character in the document nor the manner of escaping is negotiable. I'm parsing the documents using cElementTree or lxml [semi-negotiable]. Here is my best attempt at unescapeing the parser output as efficiently as possible: import re def unescape(s, subber=re.compile(r'_x[0-9A-Fa-f]{4,4}_').sub, repl=lambda mobj: unichr(int(mobj.group(0)[2:6], 16)), ): if "_" in s: return subber(repl, s) return s The above is biassed by observing a very low frequency of "_" in typical text and a better-than-doubling of speed by avoiding the regex apparatus where possible. The question: Any better ideas out there?

• Sending the variable's content to my mailbox in Python?

  - by brilliant

  I have asked this question here about a Python command that fetches a URL of a web page and stores it in a variable. The first thing that I wanted to know then was whether or not the variable in this code contains the HTML code of a web-page: from google.appengine.api import urlfetch url = "http://www.google.com/" result = urlfetch.fetch(url) if result.status_code == 200: doSomethingWithResult(result.content) The answer that I received was "yes", i.e. the variable "result" in the code did contain the HTML code of a web page, and the programmer who was answering said that I needed to "check the Content-Type header and verify that it's either text/html or application/xhtml+xml". I've looked through several Python tutorials, but couldn't find anything about headers. So my question is where is this Content-Type header located and how can I check it? Could I send the content of that variable directly to my mailbox? Here is where I got this code. It's on Google App Engines.

• Integrating a C project in the iPhone SDK

  - by iPhoneARguy

  Hello, This is my first time doing this sort of project so apologies if the question is silly. I've got a question about using a C project with a project in the iPhone SDK. I've dragged and dropped the C project into the iPhone project in Xcode (so it appears in the screenshot below). sjeng.h is a file inside GameEngine.xcodeproj, but when I try to include the header file, I not only receive an error, but the file it is looking for seems to be capitalized whereas the import statement is not. (I would post a screenshot but this is my first time doing something on stack overflow and I need more reputation points. The URL of the screenshot is here: http://imgur.com/AdrGL.png) Does anyone know what the problem might be? Thanks!

• Issue in exec method

  - by mukul sharma

  Hi all, I am a having two python files file1.py and file2.py. I am using exec() to get the method/Variables defined in the file2.py. file1.py have a class as given below class one: def init(self): self.HOOK = None exec(file2.py) self.HOOK = Generate ### call the hook method #### self.HOOK() file2.py looks like as (There is no class define in file2.py) def Generate() do 1 do 2 Hello() def hello() print "hello" Now the problem is as When i run script it is giving a error global name Hello not found. If i remove Hello() from Generate method in file2.py then its work fine. I cant use import file2.py in file1.py,because in file2.py the only one method name (Generate) is fix (its taken as requirement). So apart from Genarate method user can define any method and can call this in generate method, because this approach is not working so i have to write whole code into generate method only and code is also repetitive. Any help is really appreciable...

• How do I mock a custom field that is deleted so that south migrations run?

  - by muhuk

  I have removed an app that contained a couple of custom fields from my project. Now when I try to run my migrations I get ImportError, naturally. These fields were very basic customizations like below: from django.db.models.fields import IntegerField class SomeField(IntegerField): def get_internal_type(self): return "SomeField" def db_type(self, connectio=None): return 'integer' def clean(self, value): # some custom cleanup pass So, none of them contain any database level customizations. When I removed this code, I've created migrations so the subsequent migration all ran fine. But when I try to run them on a pre-deletion database I realized my mistake. I can re-create a bare-bones app and make these imports work, but Ideally I would like to know if South has a mechanism to resolve these issues? Or is there any best practises? It would be cool if I could solve these issues just by modifying my migrations and not touching the codebase. (Django 1.3, South 0.7.3)

• Logical python question - handling directories and files in them

  - by Konstantin

  Hello! I'm using this function to extract files from .zip archive and store it on the server: def unzip_file_into_dir(file, dir): import sys, zipfile, os, os.path os.makedirs(dir, 0777) zfobj = zipfile.ZipFile(file) for name in zfobj.namelist(): if name.endswith('/'): os.mkdir(os.path.join(dir, name)) else: outfile = open(os.path.join(dir, name), 'wb') outfile.write(zfobj.read(name)) outfile.close() And the usage: unzip_file_into_dir('/var/zips/somearchive.zip', '/var/www/extracted_zip') somearchive.zip have this structure: somearchive.zip 1.jpeg 2.jpeg another.jpeg or, somethimes, this one: somearchive.zip somedir/ 1.jpeg 2.jpeg another.jpeg Question is: how do I modify my function, so that my extracted_zip catalog would always contain just images, not images in another subdirectory, even if images are stored in somedir inside an archive.

• How can I extend a LinkButton to allow HTML text in Flex?

  - by John Isaacks

  I am feeding the label to my LinkButton directly from a string I receive from a Google API that puts html to format the label. I want to extend linkbutton to allow this. I wrote a class myself to allow html text for the label and that aspect of it works but now the background that appears when you hover is way too big. I tried to override measure() to fix this but I didn't have a clue how. Here is the class I wrote: package com.kranichs.components { import mx.controls.LinkButton; public class HTMLLinkButton extends LinkButton { protected var _isHTML:Boolean; public function HTMLLinkButton() { super(); } [Bindable] public function set isHTML(value:Boolean):void { _isHTML = value; } public function get isHTML():Boolean { return _isHTML; } override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void { super.updateDisplayList(unscaledWidth, unscaledHeight); if(_isHTML) { textField.htmlText = label; } } } }

• Command-line input causes SyntaxError

• java checked exception in a catch clause compilation error

  - by srandpersonia

  Hi, I was expecting an compilation error in the following program because of the throw statement in the catch block as IOException is a checked exception and it is not caught by another try block within the catch block. But I am getting "Hurray!" printed. Any explanation would be much appreciated. According to JLS 11.2.3, http://java.sun.com/docs/books/jls/third_edition/html/exceptions.html It is a compile-time error if a method or constructor body can throw some exception type E when both of the following hold: * E is a checked exception type * E is not a subtype of some type declared in the throws clause of the method or constructor. import java.io.*; public class Test{ public static void main(String args[]) { System.out.println(method()); } public static int method() { try{ throw new Exception(); } catch(Exception e){ throw new IOException(); //No compile time error } finally{ System.out.println("Hurray!"); } } } Thanks in advance.

• SSIS - Parallel Execution of Tasks - How efficient is it?

  - by Randy Minder

  I am building an SSIS package that will contain dozens of Sequence tasks. Each Sequence task will contain three tasks. One to truncate a destination table and remove indexes on the table, another to import data from a source table, and a third to add back indexes to the destination table. My question is this. I currently have nine of these Sequences tasks built, and none are dependent on any of the others. When I execute the package, SSIS seems to do a pretty good job of determining which tasks in which Sequence to execute, which, by the way, appears to be quite random. As I continue adding more Sequences, should I attempt to be smarter about how SSIS should execute these Sequences, or is SSIS smart enough to do it itself? Thanks.

• Is Android AVD's firewall somehow more restricted to real Android firewall?

  - by hhh

  I have a TCP server running in AVD and a TCP client running in AVD. AVD client dies because the connection refused so we are doubting some restricted firewall settings. I turned off the firewall in my Debian -laptop with this here but it did not fix the problem so some issue with Android -emulator, intro here. How can I make a TCP connection from one AVD to another AVD in the same laptop in Android? Grap the code & Minimal Working Example: You can find the sources here: import to Eclipse, set up two pieces of 2.3.3 AVDs, set up Test-running-configurations for server and client. Then "Run as Configuration" and you should see this bug. I don't have a physical Android -phone to test the code so I cannot comment whether it works with real Androids.

• Looping an executable to get the result from Python script

  In my python script, I need to call within a for loop an executable, and waiting for that executable to write the result on the "output.xml". How do I manage to use wait() & how do I know when one of my executable is finished generating the result to get the result? How do I close that process and open a new one to call again the executable and wait for the new result? import subprocess args = ("bin/bar") popen = subprocess.Popen(args) I need to wait for the output from "bin/bar" to generate the "output.xml" and from there, read it's content. for index, result in enumerate(results): myModule.callSubProcess(index) #this is where the problem is. fileOutput = open("output.xml") parseAndStoreInSQLiteFileOutput(index, file)

• Constants by another name

  - by Dave DeLong

  First off, I've seen this question and understand why the following code doesn't work. That is not my question. I have a constant, which is declared like; //Constants.h extern NSString * const MyConstant; //Constants.m NSString * const MyConstant = @"MyConstant"; However, in certain contexts, it's more useful to have this constant have a much more descriptive name, like MyReallySpecificConstant. I was hoping to do: //SpecificConstants.h extern NSString * const MyReallySpecificConstant; //SpecificConstants.m #import "Constants.h" NSString * const MyReallySpecificConstant = MyConstant; Obviously I cannot do this (which is explained in the linked question above). My question is: How else (besides something like #define MyReallySpecificConstant MyConstant) can I provide a single constant under multiple names?

• Handling Datetime with decimal '2010-02-14 20:18:58.313000000'

  - by AaronLS

  In SQL Server I have some textual data in varchar fields I am trying to convert to datetime's. The funny thing is this data at some point was in a datetime field, exported to flat file, and now I am reimporting it. The problem is it is in this format 2010-02-14 20:18:58.313000000 and the conversion to datetime fails. I have no idea how it ended up like this when it was originally extracted from a datetime column. Basically a table was exported to a flat file by someone else. The original table was lost. I am reimporting back from the flatfile. I could just drop the decimal but this would be like throwing out some of the data. I'd like to maintain as much precision as possible. How can I import this data from the varchar column back into a datetime column and preserve as much accuracy as possible?
