• abstract class NumberFormat - very confused about getInstance()

  - by Alex

  Hi, I'm new to Java and I have a beginner question: NumberFormat is an abstract class and so I assume I can't make an instance of it. But there is a public static (factory?) method getInstance() that allow me to do NumberFormat nf = NumberFormat.getInstance(); I'm quite confuse. I'll be glad if someone could give me hints on: 1) If there is a public method to get an instance of this abstract class, why don't we have also a constructor? 2) This is an abstract class ; how can we have this static method giving us an instance of the class? 3) Why choosing such a design? If I assume it's possible to have an instance of an abstract class (???), I don't get why this class should be abstract at all. Thank you.

• Weird behaviour of the app.config deployment after updating it.

  - by Dabblernl

  I moved some hardcoded settings to a custom Section (so I did not use the <appSetting tag) in the app.config of my ClickOnce application. When updating, the clients got an error stating that the server gave a 404 not found error for the file "myapp.exe.config.deploy". Browsing on the server I did find the changed app.config there, only it was named app.config.deploy. Thinking to be smart I renamed the app.config to myapp.exe.config on the development machine and published again. That did not work... However after naming the file back to app.config and publishing the error went away and the clients used the setting happily! Please explain what went wrong?

• Rename parameter in a WCF client interface

  - by user295479

  Hello everyone, I was wondering if there is a way to rename a parameter in a WCF client interface method ,just the same way I can rename methods or enumerations: Renaming methods: [System.Runtime.Serialization.DataMemberAttribute(Name = "intError")] public int ErrorCode {...} Renaming enumerations: public enum MyEnumeration: int { [System.Runtime.Serialization.EnumMemberAttribute()] None = 0, [System.Runtime.Serialization.EnumMemberAttribute(Value = "FirstOption")] First= 1, [System.Runtime.Serialization.EnumMemberAttribute()] SecondOption= 2, } Renaming parameters?? I want to rename an interface parameter named "error" which FxCop doesn't like. Any help will be appreciated. Thank you.

• UNIX Timestamp to MySQL DATETIME

  - by Henk Denneboom

  Hi all, I have a table with statistics and a field named time with Unix Timestamps. There are about 200 rows in the table, but I would like to change the Unix timestamps to MySQL DATETIME. Without losing the current rows. What would be the best way to update the Unix Timestamp to MySQL's DATETIME? The current table: CREATE TABLE `stats` ( `id` int(11) unsigned NOT NULL auto_increment, `time` int(11) NOT NULL, `domain` varchar(40) NOT NULL, `ip` varchar(20) NOT NULL, `user_agent` varchar(255) NOT NULL, `domain_id` int(11) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 So the time (INT) should be a DATETIME field. Thanks in advance!

• 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

• C# Winforms: How to display a loading form?

  - by Martijn

  I have a grid and when a row is double clicked a form is loaded. However a lot of data must be loaded, so I'd like to display a simple form with the text 'loading, please wait..'. And when all loading is finished, the form must disappear. This is what I have right now, but it doesn't work: Code that invokes the form with lots of data: FormWithLotData form = new FormWithLotData(); form.ShowDialog(this); Constructor of FormWithLotData: // Show load form FormIsLoading frm = new FormIsLoading(); _CloseLoadForm closeForm = new _CloseLoadForm(frm.Close); System.Threading.Thread thread = new System.Threading.Thread(frm.Show); thread.Start(); InitializeComponent(); this.Visible = false; LoadAllData(); this.Visible = true; // Close load form Invoke(closeForm); Hope you can help me out.

• Parsing XML using xml.etree.cElementTree

  - by Andre

  I have the following XML in a string named 'xml': <?xml version="1.0" encoding="ISO-8859-1"?> <Book> <Page> <Text>Blah</Text> </Page> </Book> I'm trying to get the value Blah out of it but I'm having trouble with xml.etree.cElementTree. I've tried the find() and findtext() methods but nothing. Eventually I did this: import xml.etree.cElementTree as ET ... root = ET.fromstring(xml) element = root.getchildren()[0].getchildren()[0] Element now equals the element, which is what I want (for this solution anyway), but how do I get the inner text from it? element.text does not work. Any ideas? PS: I am using Python 2.5 atm. As an extra question: what is a better way to parse xml strings in python?

• Read XML file from ADO (VB6) Into .Net DataSet

  - by Jimbo

  I am trying to assist users in migrating from a VB6 application to a C# application. The VB6 app allows the export of data from an ADO (2.8) recordset via XML, but the C# application fails to read the XML producing the following error: System.Data.DuplicateNameException: A column named 'name' already belongs to this DataTable VB6 Code Dim RS As Recordset Set RS = p_CN.Execute("SELECT * FROM tblSuppliers INNER JOIN tblSupplierGroups ON tblSupplierGroups.SupplierGroupID=tblSuppliers.SupplierGroupID") RS.Save sDestinationFile, adPersistXML Set RS = Nothing C# Code DataSet ds = new DataSet(); ds.ReadXml(xmlFilePath); I have obviously incorrectly assumed that the XML file format was universally understood?

• Pulling and pushing between two google code repositories

  - by Kim L

  I'll start by quoting google's blog Project owners can now create multiple repositories for their project, and they can choose to make any of those new repositories a clone of any of the project's other repositories. These project clones share the same commit access permissions as the original project and make it easier for project members to work together on new features. A common pattern in the Mercurial world is to place each "official" branch into a separate repository with naming conventions like "project-crew", "project-stable", and so on. I've done exactly this. I have my default repository and then I've cloned that repository to a repo named "dev". I intend to use the default repository as my stable repo and then the dev repo as my primary development repo. Now I'm just wondering how on earth I should go about to pull and push between the default and the dev repositories?

• Combine guava's ImmutableList and varargs

  - by Stas Kurilin

  I want create constructor that will take one or more integers and save it into field as ImmutableList. According to "The right way to use varargs to pass one or more arguments" by Bloch's Item 42 I create smt like class Foo{ private final ImmutableList<Integer> bar; public Foo(Integer first, Integer... other) { this.bar = ImmutableList.<Integer>builder() .add(first) .addAll(Arrays.asList(other)) .build(); } } Why builder doesn't get generic automatically? And, as it smells. How I can rewrite it?

• Converting Oracle date arithmetic to work in HSQLDB

  - by JBristow

  I'm trying to spot-test an Oracle backed database with hsqldb and dbunit, but I've run into a snag. The problem is with the following EJB-QL (simplified a bit): SELECT o FROM Offer o WHERE :nowTime BETWEEN o.startDate AND o.startDate + 7 This seems to only work in Oracle's version of SQL. What's the easiest way for me to convert this to work in both hsqldb and oracle? Assume that changing the two between arguments to named parameters is a very difficult refactor, so I'm going to favor answers that provides a more standardized analog to o.startdate + 7 EDIT: After doing some more research, it looks like Oracle converts the above snippet to o.startdate + INTERVAL '7' DAY which is apparently more standard, but doesn't work in HSQLDB.

• Testing Rails Metal/Rack with RSpec?

  - by Matt Darby

  Say I have a Metal class named Preview. How do I test it with RSpec? When I try: require 'spec_helper' describe Preview do it "should return the posted content" do post "/preview", :content => "*title*" response.body.should == "*title*" end end I get: undefined method `post' for #<ActiveSupport::TestCase::Subclass_1:0x1058b3098> It seems that RSpec doesn't load up the :post method if the test isn't explicitly for a Controller. I've tried specifying :type => :controller to no avail.

• scvmap, disco, xsd, wsdl, svcinfo and datasource files

  - by David Gray Wright

  We have a WEb Service named, let's say Foo. So there is a Foo.svc file and a code behind Foo.svc.cs. We add a silverlight project and wish to use the Foo.svc services so we add a Service Reference and call it's namespace FooBar. This creates the following files : Reference.cs Reference.svcmap Foo.xsd Foo.disco configuration.svcinfo Foo.wsdl Also various *.datasource files. Over time we update the Foo.svc and add more Web Services (methods and interfaces) and the number of files in the FooBar directory is growing. I have 26 Foo(nn).xsd files in this directory - where nn = 1 to 26. My configuration.svcinfo is upto configuration91.svcinfo. My question is this? Do any of these files need to be version controlled? Can they all be deleted each time you do a build \ deploy (as long as you do an update service reference)?

• Problem with constants in application.ini after PHP upgrade

  - by Marek

  Hi, I've upgraded PHP on my local dev system to version 5.3.0, and there is some problem when I use constants in application.ini - following manual http://framework.zend.com/manual/en/learning.quickstart.create-project.html I have: bootstrap.path = APPLICATION_PATH "/Bootstrap.php" which leads to: Warning: require_once(APPLICATION_PATH/Bootstrap.php) [function.require-once]: failed to open stream: No such file or directory in Zend\Application.php on line 320 any ideas? SOLVED: Actually name of my constant was _DIR_APPLICATION (code above was copied from ZF manual) - problem lies in this underscore at the begining - it seems that parse_ini_file() in PHP 5.3.0 doesn't replace constants named like this. Short test - you need two files: test.ini bootstrap.path = _DIR_APPLICATION "/Bootstrap.php" bootstrap.class = "Bootstrap" and test.php <?php define('_DIR_APPLICATION', 'test'); $data = parse_ini_file('test.ini'); print_r($data); try to run, then change constant name to 'DIR_APPLICATION' (in both files) and compare result ;)

• Laws of Computer Science and Programming

  - by Jonas

  We have Amdahl's law that basically states that if your program is 10% sequential you can get a maximum 10x performance boost by parallelizing your application. Another one is Wadler's law which states that In any language design, the total time spent discussing a feature in this list is proportional to two raised to the power of its position. 0. Semantics 1. Syntax 2. Lexical syntax 3. Lexical syntax of comments My question is this: What are the most important (or at least significant / funny but true / sad but true) laws of Computer Science and programming? I want named laws, and not random theorems, So an answer should look something like Surname's (law|theorem|conjecture|corollary...) Please state the law in your answer, and not only a link. Edit: The name of the law does not need to contain it's inventors surname. But I do want to know who stated (and perhaps proved) the law

• Android: No icon for Notification

  - by Omer

  Hello, I wanted to create a notification without the icon in the status bar (the state that is not expanded). I tried the custom expanded view and set the icon for this view only. But it did not work. When I give 0 as icon to the constructor, the icon disappears but notification also does not appear in the expanded view. Notification notification = new Notification(0, "", 0); I tried a lot of combinations but didn't come out with a solution. By the way, I know it is working because I saw this feature in some apps. Thanks.

• Jython project in Eclipse can't find the Jython library, but works in an identical project

  - by Rob Lourens

  I have two projects in Eclipse with Java and Python code, using Jython. Also I'm using PyDev. One project can import and use the xml module just fine, and the other gives the error ImportError: No module named xml. As far as I can tell, all the project properties are set identically. The working project was created from scratch and the other comes from code checked out of an svn repository and put into a new project. What could be the difference?

• windows mobile 6.5 Gestures and DirectDraw

  - by ArjanW

  I'm trying to build a UI using directdraw in c#. For this im using a DirectDrawWrapper as sugested here. My initial tests setting up the screen work perfectly. But now i'd like to incorporate gesture recognition into the UI. So i instantiate a GestureRecognizer and tie it to the _form which also gets passed to the DirectDrawGraphics constructor, form = new Form(); _form.show(); _graphics = new DirectDrawGraphics(_form, CooperativeFlags.Fullscreen, BackbufferMode.Any); gestureRecognizer = new GestureRecognizer(); gestureRecognizer.TargetControl = _form; Pasting the whole DirectDrawWrapper code might be a bit to much, so let me try to formulate a question. I guess directdraw talks directly to the video memory, as it should. But then my form wont receive any messages, thus any eventhandlers i'v tied op to the GestureRecognizer wont be fired. How can i still receive any messages from the touchscreen?

• Why can't I log in with "claimid.com" as an OpenID?

  - by radu-negrila

  Hi, I need to implement a relying party for Open ID in a load balanced environment. Following the suggestions found here I have tried passing null to the OpenIdRelyingParty constructor. The results are somehow not consistent. If I use www.myopenid.com as a provider it works. If I use www.claimid.com as a provider I get the following exception: ProtocolException - No OpenID endpoint found. This exception is thrown on the CreateRequest method call even in a non balanced environment (my local workstation). Any idea what can I do to make it work for both providers ?

• I'm working on Peano Axioms in Agda and I've hit a bit of a sticking point

  PA6 : ?{m n} -> m = n -> n = m is the axiom I am trying to solve and support, I've tried using a cong (from the core library) but am having troubles with the cong constructor PA6 = cong gets me nowhere, I know for cong I am required to supply a refl for equality and a type, but I'm, not sure what type I'm supposed to supply. Ideas? This is for a small assignment at University, so I'd rather someone demonstrate what I've missed rather than write the acutual answer, but I'd appreciate any degree of support.

• SqlDateTime overflow thrown by Typed DataSet Insert

  - by end-user

  I'm using a Typed DataSet with an Insert statement; I have a table that has a smalldatetime field defined to accept null values. When I insert from a .NET 2.0 FormView, I get a "SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM." Now, I've read this post, and the parameter as sent to the class constructor is defined as global::System.Nullable<global::System.DateTime> DoB So, it looks like it should accept a Nullable obj. Additionally, the generated code is testing the value sent. if ((DoB.HasValue == true)) { command.Parameters[6].Value = ((System.DateTime)(DoB.Value)); } else { command.Parameters[6].Value = global::System.DBNull.Value; } Specifically, the error is occurring when generated SqlClient.SqlCommand.ExecuteScalar() runs: try { returnValue = command.ExecuteScalar(); } So, I guess my question is: how do I use a Typed DataSet to set a blank value (passed from a FormView on CommandName=Insert) to a null in a database?
