• 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 remove a few lines from a Unicode registry file using batch commands in Windows?

  - by Cosmin

  Hi. I have a program who's generating some data in registry. I save it with "reg export HKCU\Software\ProgramName\Data data.reg" (Unicode format). I need to take it to other computer and import it there so the program from that computer could use the data. But I have to remove some text lines from data.reg. The text lines are easy to find because they contain some strings. Now I'm doing this manually (using Wordpad) every few days but maybe there is another way... Oh and I can't install other programs on these computers (the access is restricted) so I have to use batch/cmd files. What I tried so far: - redirecting the export to "con" but is visual only not in a variable; - using "for /F ..." but this works only with ANSI and removes blank lines. Can somebody please help me...? Thank you.

• 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.

• HOWTO: Deserialize WCF message using OperationContract

  - by Stefan

  Hi, I succeeded in building a WCF client generated by svcutil.exe from the WSDL. Using the generated client proxy class I can call the web service of an external service supplier. I also succeeded in coding a message inspector, as I need to log both raw XML request and response as full SOAP message to the database. For an emergency szenario I also need to be able to "import" a raw XML response. I found many hints on using XMLSerializer or deserializing WCF messages based on the message contract. But how can I deserialize a raw XML response based on an operation contract? For a first test I use one of the logged raw responses, save it to a file and now try to deserialize it to the response type as generated in the client proxy. Somehow I must succeed in calling DeserializeReply() from class ClientOperation. But how to get there? I happily acced any help as I'm quite new to WCF... TIA, Stefan

• 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];

• 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?

• 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.

• Getting Unit Tests to work with Komodo IDE for Python

  - by devoured elysium

  I've tried to run the following code on Komodo IDE (for python): import unittest class MathLibraryTests(unittest.TestCase): def test1Plus1Equals2(self): self.assertEqual(1+1, 2) Then, I created a new test plan, pointing to this project(file) directory and tried to run it the test plan. It seems to run but it doesn't seem to find any tests. If I try to run the following code with the "regular" run command (F7) class MathLibraryTests(unittest.TestCase): def testPlus1Equals2(self): self.assertEqual(1+1, 2) if __name__ == "__main__": unittest.main() it works. I get the following output: ---------------------------------------------------------------------- Ran 1 test in 0.000s OK What might I be doing wrong?

• 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.

• Using Hive in a maven project

  - by Jason

  I have a project that I am migrating from ant to maven. The project makes use of a lightly-customized Hive build. I figured I would just import this build into our internal maven repo and list it as a dependency in the project's pom file. The problem I'm running into is that the Hive build just generates a bunch of jars in build/dist/lib. Some of these are the core Hive jars themselves and some are jars that Hive depends on. What's the best way to deal with these? Should I put all the core hive jars into our internal repo and just deal with undocumented dependencies in the new project's pom file? Or just jar up everything as a jar of jars and deploy that to the repo? Would that approach even work? Kind of a maven newbie still, thanks for any help.

• 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.

• SQLAlchemy - how to map against a read-only (or calculated) property

  - by Jeff Peck

  I'm trying to figure out how to map against a simple read-only property and have that property fire when I save to the database. A contrived example should make this more clear. First, a simple table: meta = MetaData() foo_table = Table('foo', meta, Column('id', String(3), primary_key=True), Column('description', String(64), nullable=False), Column('calculated_value', Integer, nullable=False), ) What I want to do is set up a class with a read-only property that will insert into the calculated_value column for me when I call session.commit()... import datetime def Foo(object): def __init__(self, id, description): self.id = id self.description = description @property def calculated_value(self): self._calculated_value = datetime.datetime.now().second + 10 return self._calculated_value According to the sqlalchemy docs, I think I am supposed to map this like so: mapper(Foo, foo_table, properties = { 'calculated_value' : synonym('_calculated_value', map_column=True) }) The problem with this is that _calculated_value is None until you access the calculated_value property. It appears that SQLAlchemy is not calling the property on insertion into the database, so I'm getting a None value instead. What is the correct way to map this so that the result of the "calculated_value" property is inserted into the foo table's "calculated_value" column?

• 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)

• Why can't my main class see the array in my calender class

  - by Rocky Celltick Eadie

  This is a homework problem. I'm already 5 days late and can't figure out what I'm doing wrong.. this is my 1st semester in Java and my first post on this site Here is the assignment.. Create a class called Calendar. The class should contain a variable called events that is a String array. The array should be created to hold 5 elements. Use a constant value to specify the array size. Do not hard code the array size. Initialize the array in the class constructor so that each element contains the string “ – No event planned – “. The class should contain a method called CreateEvent. This method should accept a String argument that contains a one-word user event and an integer argument that represents the day of the week. Monday should be represented by the number 1 and Friday should be represented by the number 5. Populate the events array with the event info passed into the method. Although the user will input one-word events, each event string should prepend the following string to each event: event_dayAppoinment: (where event_day is the day of the week) For example, if the user enters 1 and “doctor” , the first array element should read: Monday Appointment: doctor If the user enters 2 and “PTA” , the second array element should read: Tuesday Appointment: PTA Write a driver program (in a separate class) that creates and calls your Calendar class. Then use a loop to gather user input. Ask for the day (as an integer) and then ask for the event (as a one word string). Pass the integer and string to the Calendar object’s CreateEvent method. The user should be able enter 0 – 5 events. If the user enters -1, the loop should exit and your application should print out all the events in a tabular format. Your program should not allow the user to enter invalid values for the day of the week. Any input other than 1 – 5 or -1 for the day of the week would be considered invalid. Notes: When obtaining an integer from the user, you will need to use the nextInt() method on your Scanner object. When obtaining a string from a user, you will need to use the next() method on your Scanner object. Here is my code so far.. //DRIVER CLASS /** * * @author Rocky */ //imports scanner import java.util.Scanner; //begin class driver public class driver { /** * @paramargs the command line arguments */ //begin main method public static void main(String[] args) { //initiates scanner Scanner userInput = new Scanner (System.in); //declare variables int dayOfWeek; String userEvent; //creates object for calender class calendercalenderObject = new calender(); //user prompt System.out.println("Enter day of week for your event in the following format:"); System.out.println("Enter 1 for Monday"); System.out.println("Enter 2 for Tuesday"); System.out.println("Enter 3 for Wednsday"); System.out.println("Enter 4 for Thursday"); System.out.println("Enter 5 for Friday"); System.out.println("Enter -1 to quit"); //collect user input dayOfWeek = userInput.nextInt(); //user prompt System.out.println("Please type in the name of your event"); //collect user input userEvent = userInput.next(); //begin while loop while (dayOfWeek != -1) { //test for valid day of week if ((dayOfWeek>=1) && (dayOfWeek<=5)){ //calls createEvent method in calender class and passes 2 variables calenderObject.createEvent(userEvent,dayOfWeek); } else { //error message System.out.println("You have entered an invalid number"); //user prompts System.out.println("Press -1 to quit or enter another day"); System.out.println("Enter 1 for Monday"); System.out.println("Enter 2 for Tuesday"); System.out.println("Enter 3 for Wednsday"); System.out.println("Enter 4 for Thursday"); System.out.println("Enter 5 for Friday"); System.out.println("Enter -1 to quit"); //collect user input dayOfWeek = userInput.nextInt(); //end data validity test } //end while loop } //prints array to screen int i=0; for (i=0;i<events.length;i++){ System.out.println(events[i]); } //end main method } } /** * * @author Rocky */ //imports scanner import java.util.Scanner; //begin calender class public class calender { //creates events array String[] events = new String[5]; //begin calender class constructor public calender() { //Initializes array String[] events = {"-No event planned-","-No event planned-","-No event planned-","-No event planned-","-No event planned-"}; //end calender class constructor } //begin createEvent method public String[] createEvent (String userEvent, int dayOfWeek){ //Start switch test switch (dayOfWeek){ case 1: events[0] = ("Monday Appoinment:") + userEvent; break; case 2: events[1] = ("Tuesday Appoinment:") + userEvent; break; case 3: events[2] = ("WednsdayAppoinment:") + userEvent; break; case 4: events[3] = ("Thursday Appoinment:") + userEvent; break; case 5: events[4] = ("Friday Appoinment:") + userEvent; break; default: break; //End switch test } //returns events array return events; //end create event method } //end calender class }

• Inserting multiple types into an SQLite database with Python

  - by mankoff

  I'm trying to create an SQLite 3 database from Python. I have a few types I'd like to insert into each record: A float, and then 3 groups of n floats, currently a tuple but could be an array or list.. I'm not well-enough versed in Python to understand all the differences. My problem is the INSERT statement. DAS = 12345 lats = (42,43,44,45) lons = (10,11,12,13) times = (1,2,3,4,5,6,7,8,9) import sqlite3 connection = sqlite3.connect("test.db") cursor = connection.cursor() cursor.execute( "create table foo(DAS LONG PRIMARY KEY,lats real(4),lons real(4), times real(9) )" ) I'm not sure what comes next. Something along the lines of: cmd = 'INSERT into foo values (?,?,?,?), ..." cursor.execute(cmd) How should I best build the SQL insert command given this data?

• 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.

• What's the funniest user request you've ever had?

  - by Shaul

  Users sometimes come up with the most amusing, weird and wonderful requirements for programmers to design and implement. Today I read a memo from my boss that we need the "ability to import any excel or access data, irrespective of size, easily and quickly." From the same memo, we have a requirement to "know if anyone unauthorized accessed the system" - as if a hacker is going to leave his calling card wedged between an index and a foreign key somewhere. I think my boss has been watching too much "Star Trek"... :) What's the funniest user request you've ever had?

• 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?

• Preview result of update/insert query whithout comitting changes to database in MySQL?

  - by Camsoft

  I am writing a script to import CSV files into existing tables within my database. I decided to do the insert/update operations myself using PHP and INSERT/UPDATE statements, and not use MySQL's LOAD INFILE command, I have good reasons for this. What I would like to do is emulate the insert/update operations and display the results to the user, and then give them the option of confirming that this is OK, and then committing the changes to the database. I'm using InnoDB database engine with support for transactions. Not sure if this helps but was thinking down the line of insert/update, query data, display to user, then either commit or rollback transaction? Any advise would be appreciated.

• BASH Install Of Wordpress, Without Visiting wp-admin/install.php

  - by user916825

  I wrote this little BASH script that creates a folder,unzips Wordpress and creates a database for a site. The final step is actually installing Wordpress, which usually involves pointing your browser to install.php and filling out a form in the GUI. I want to do this from the BASH shell, but can't figure out how to invoke wp_install() and pass it the parameters it needs: -admin_email -admin_password -weblog_title -user_name (line 85 in install.php) Here's a similar question, but in python #!/bin/bash #ask for the site name echo "Site Name:" read name # make site directory under splogs mkdir /var/www/splogs/$name dirname="/var/www/splogs/$name" #import wordpress from dropbox cp -r ~/Dropbox/Web/Resources/Wordpress/Core $dirname cd $dirname #unwrap the double wrap mv Core/* ./ rm -r Core mv wp-config-sample.php wp-config.php sed -i 's/database_name_here/'$name'/g' ./wp-config.php sed -i 's/username_here/root/g' ./wp-config.php sed -i 's/password_here/mypassword/g' ./wp-config.php cp -r ~/Dropbox/Web/Resources/Wordpress/Themes/responsive $dirname/wp-content/t$ cd $dirname CMD="create database $name" mysql -uroot -pmypass -e "$CMD" How do I alter the script to automatically run the installer without the need to open a browser?

• 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?
