• Branch by abstraction: Are there "examples" of how it can be done?

  - by Philipp Keller

  Having read Martin Fowlers "Feature Branch" and Flickrs "Flipping Out" (http://www.liip.to/flippingout) I guess there are a few guys out there who do: all (or most) development on Trunk release Trunk regularly (assuming updating your web site) not-yet-approved or not-yet-finished features should not be visible/have no impact on the regular user I've got 2 questions: granted - Flickr's article seems to work for "frontend code". But how is it cleaned up? Don't the ifs pile up? how does this work for the more "backend part"? Thinking of database changes, or model refactoring. Working with ifs doesn't seem to work - and copy-pasting classes for small adaptions also seems awkward. Are there any articles out there answering these 2 questions?

• linq to sql dynamic data modify object before insert and update

  - by Dan Tanner

  I'm using Dynamic Data and LINQ to SQL for some admin pages on a .NET 3.5 web app. All my admin tables a CreatedBy, CreatedDate, UpdatedBy, and UpdatedDate. I'm looking for a way to inject the setting of these properties before the objects are inserted and updated. I've seen an object_inserting hook if you have a linq to sql datasource in the web form, but I'm using dynamic data...is there an easy way to generically set that? And I've also looked at modifying each of the partial classes for my admin objects, but the closest hook I see is to implement the OnValidate method with the Insert action. Any suggestions? TIA.

• MyClass cannot be cast to java.lang.Comparable: java.lang.ClassCastException

  - by user2234225

  I am doing a java project and I got this problem and don't know how to fix it. The classes in my project (simplified): public class Item { private String itemID; private Integer price; public Integer getPrice() { return this.price; } } public class Store { private String storeID; private String address; } public class Stock { private Item item; private Store store; private Integer itemCount; public Integer getInventoryValue() { return this.item.getPrice() * this.itemCount; } } Then I try to sort an ArrayList of Stock so I create another class called CompareByValue public class CompareByValue implements Comparator<Stock> { @Override public int compare(Stock stock1, Stock stock2) { return (stock1.getInventoryValue() - stock2.getInventoryValue()); } } When I try to run the program, it gives the error: Exception in thread "main" java.lang.ClassCastException: Stock cannot be cast to java.lang.Comparable Anyone know what's wrong?

• Formatting address of different types

  - by mickyjtwin

  I have various classes which all contain address details, i.e. AddressLine1, AddressLine2, AddressLine3, Suburb, Town, etc. On the front end, I need to format the address in a particular way, i.e. AddressLine1<br /> AddressLine2<br /> Suburb State Postcode If AddressLine2 does not exist or empty, don't show it. Quite straight-forward. I am trying to determine the best way to show this info. At the moment, the Address property of each class calls a FormatAddress method which writes out the html string. This exists as a method of the class. My opinion is that any formatting should exist from the front-end control i.e. ascx etc. However, if these DetailClasses need to format the same address info, what would be the best option, also making it easier to maintain?

• optional local variables in rails partial templates: how do I get out of the (defined? foo) mess?

  - by brahn

  I've been a bad kid and used the following syntax in my partial templates to set default values for local variables if a value wasn't explicitly defined in the :locals hash when rendering the partial -- <% foo = default_value unless (defined? foo) %> This seemed to work fine until recently, when (for no reason I could discern) non-passed variables started behaving as if they had been defined to nil (rather than undefined). As has been pointed by various helpful people on SO, http://api.rubyonrails.org/classes/ActionView/Base.html says not to use defined? foo and instead to use local_assigns.has_key? :foo I'm trying to amend my ways, but that means changing a lot of templates. Can/should I just charge ahead and make this change in all the templates? Is there any trickiness I need to watch for? How diligently do I need to test each one?

• Unbelievable: Cannot cast from class X to its super class

  - by Phuong Nguyen de ManCity fan

  I'm encountering a very weird problem with Spring (3.0.1.RELEASE), TestNG (5.11) and Maven Surefire (2.5). I have a test class that extends a Spring helper class for testNG so that test context can be loaded from an xml file (that contains some bean definitions). My project was imported into eclipse using m2eclipse (using Import Maven Project) The class run fine in Eclipse TestNG runner. However, it throws this exception with Maven Surefire Caused by: java.lang.ClassCastException: com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl cannot be cast to javax.xml.parsers.DocumentBuilderFactory at javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:123) at org.springframework.beans.factory.xml.DefaultDocumentLoader.createDocumentBuilderFactory(DefaultDocumentLoader.java:89) at org.springframework.beans.factory.xml.DefaultDocumentLoader.loadDocument(DefaultDocumentLoader.java:70) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:388) I have eliminated all involved dependencies in my pom so that the two classes com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl and javax.xml.parsers.DocumentBuilderFactory are coming from JRE only (the rt.jar). So, it looks so unbelievable to me. I wonder if there is any mechanism in loading class that can explain for this behavior? Thanks.

• How to Add a File from my source tree to Maven Site

  - by Charles O.

  I have a Maven 2 RESTful application using Jersey/JAXB. I generate the JAXB beans from a schema file, where the schema file is in my resources directory, e.g., src/main/resources/foo.xsd. I want to include foo.xsd file in the generated Maven site for my project, so that clients can see the XML schema when writing RESTful calls. How can I include foo.xsd in the site? I could have a copy of the file in src/main/site/..., and then update my site.xml to point to it (or have a .apt whose contents point to it), but I don't like that because I'm still tweaking foo.xsd, and don't want to have to remember to copy it each time I update it. And that's just bad practice. I also tried having a .apt file that has a link to the foo.xsd which gets copied to the target/classes directory. That works until I do a site:deploy, because that only copies the target/site directory. Thanks, Charles

• Override number of parameters of pure virtual functions

  - by Jir

  I have implemented the following interface: template <typename T> class Variable { public: Variable (T v) : m_value (v) {} virtual void Callback () = 0; private: T m_value; }; A proper derived class would be defined like this: class Derived : public Variable<int> { public: Derived (int v) : Variable<int> (v) {} void Callback () {} }; However, I would like to derive classes where Callback accepts different parameters (eg: void Callback (int a, int b)). Is there a way to do it?

• What's the difference between IEquatable and just overriding Object.Equals() ?

  - by devoured elysium

  I want my Food class to be able to test whenever it is equal to another class. I will later use it against a List, and I want to use its List.Contains() method. Should I implement IEquatable or just override Object.Equals()? From MSDN: This method determines equality by using the default equality comparer, as defined by the object's implementation of the IEquatable.Equals method for T (the type of values in the list). So my next question is: which functions/classes of the .NET framework make use of Object.Equals()? Should I use it in the first place? Thanks

• Eclipse refresh taking too long

  - by Nash0

  I am doing TDD on a large Java project in eclipse and am finding it frustrating because every time I run a test I have to wait 30 seconds+ for eclipse to compile and refresh. I estimate that 80%+ of that time is spent refreshing. Is there a way I can drastically reduce the amount of refreshing it is doing? I have looked at server other similar questions but I could not see anything that helps. One way I reduced the compile refresh time was to split the unit tests and code into separate projects. There are 4,700 classes in the src project and 300 in the tests. I am running eclipse 3.5.1 on Java 1.6.0_17-b04 (eclipse.vm). My computer is running windows xp with 3.1 gigs of usable ram. The only plugin I have installed is subclipse.

• IDL in ATL/COM: Can I publish a const of a complex type?

  - by Ptah- Opener of the Mouth

  I know how to publish a const of a simple type in IDL, for example: const long blah = 37 But I want to publish consts of complex types, with methods, or at least readable struct-like member fields. For example, perhaps a type called CarType, which has accessor fields like "get_Make", "get_Model", "get_Year", "get_BasePrice", et cetera. Then I would like to publish const instances, such as FORD_PINTO_1973. (Please don't read too much into the example, to tell me that this particular example would lend itself better to just regular classes without const instances or something like that). I have no idea how I would define, in IDL, the fact that FORD_PINTO_1973 has a Year field of 1973. Thanks in advance for any help.

• C# UserControl factory

  - by user1112111

  Let's say you have two classes that extend UserControl. Each of the controls provides a custom event (this could be done by using an interface). You want to display one of the controls in the odd days and the other in the even days. You also want to be able to drag&drop (Visual Studio) the UserControl on your form without knowing what the Control type will finally be. How do you do that ? Is the factory pattern useful here ?

• c# binarysearch a list<T> by a member of T

  - by Pygmy

  I have a baseclass Event with a DateTime member TimeStamp. Lots of other event-classes will derive from this. I want to be able to search a list of events (that can contain events with duplicate timestamps) fast, so I'd like to use a binary search. So I started out writing something like this : public class EventList<T> : List<T> where T : Event { private IComparer<T> comparer = (x, y) => Comparer<DateTime>.Default.Compare(x.TimeStamp, y.TimeStamp); public IEnumerable<T> EventsBetween(DateTime inFromTime, DateTime inToTime) { // Find the index for the beginning. int index = this.BinarySearch(inFromTime, comparer); // BLAH REST OF IMPLEMENTATION } } The problem is that the BinarySearch only accepts T (so - an Event type) as parameter, while I want to search based on a member of T - the TimeStamp. What would be a good way to approach this ?

• HTML CSS two columns

  - by Marki

  If my HTML says something along the following <div class="container"> <div class="element"> </div> <div class="element"> </div> [...] <div class="element"> </div> </div> is it then possible to align those elements as if they were in a two-column table? I.e. with 7 elements there would be 4 rows, with the last row only having one element. (The elements themselves have NO special classes or ids like right,left,etc.)

• is there a way using Ruby's net/http to post form data to an http proxy?

  - by Derek P.

  I have a basic Squid server setup and I am trying to use Ruby's Net::HTTP::Proxy class to send a POST of form data to a specified HTTP endpoint. I assumed I could do the following: Net::HTTP::Proxy(my_host, my_port).start(url.host) do |h| req = Net::HTTP::Post.new(url.path) req.form_data = { "xml" => xml } h.request(req) end But, alas, proxy vs. non-proxied Net::HTTP classes don't seem to use the proxy IP Address. my remote service responds telling me that it received a request from the wrong IP address, ie: not the proxy. I am looking for a specific way to write the procedure, so that I can successfully send a form post via a proxy. Help? :)

• Refactoring a C# derived class with method dependancies

  - by drelihan

  Hi Folks, I want to get your opinion on this. I have a class which is derived from a base class. I don't have control over the code in the base class and it is critical to the system that I derive from it. In my class I inherite two methods that are critical to the system and are used in pretty much every function, many times. I intend to refactor this derived class and extract some classes from it - this won't be a problem. What I'm not sure about is, is it worth extracting class if I have to constantly make call backs to my main class to access the two methods (or public wrappers to the methods)??? Thanks

• 404 Error using Flash Builder 4 BlazeDS wizard

  - by codeflayer

  Hello again Stackoverflow! My issue this time around is trying to use the new DCD BlazeDS wizard in Flash Builder 4. If I set my project up as a combined Java/Flex app I am unable to connect to the RDS servlet using the wizard. I get a 404 error every time. I'm certain the service is set up correctly since my app can access the exposed java classes and BlazeMonster can see the exposed services. Is anyone else having this issue and if so has anyone found a work-around? I'd very much like to use the code generation features of the wizard for my project. Thanks as always, Codeflayer

• To see javascript object properties and functions with intellisense in VS.NET 2008

  - by uzay95

  I am creating classes in external files.And adding them with <script src='../js/clsClassName.js' type='text/javascript'></script> tags. When i created an object from this class I can't access its props, and functions with intellisense. Is there any way to achieve this? Sample javascript class: // clsClassName.js function ClassName(_param1, _param2, _param3) { this.Prop1 = _param1; this.Prop1 = _param2; this.Prop3 = _param3; } ClassName.prototype.f_Add = function(fBefore, fSuccess, fComplete, fError) { } ClassName.prototype.f_Delete = function(fBefore, fSuccess, fComplete, fError) { } Any help would be greatly appreciated...

• Perform selector on parent NSOperation

  - by user326943

  I extend NSOperation (call it A) which contains NSOperationQueue for other NSOperations (which is another extended class different from A, call these operations B). When operation A is running (executing B operations) how do i call a specific function/method on operation A when certain event takes place on B operations? For example every operation B that finishes it calls a function on operation A returning itself? *Nested NSOperation and NSOperationQueue(s) Hope this mockup pseudo code can help to draw the picture. //My classes extended from NSOperation NSOperation ClassA NSOperation ClassB //MainApp -(void)applicationDidFinishLaunching:(NSNotification *)aNotification { ClassA A1; ClassA A2; NSOperationQueue Queue; Queue AddOperation: A1; Queue AddOperation: A2; } //Main of ClassA -(void)main { ClassB B1; ClassB B2; NSOperationQueue Queue; Queue AddOperation: B1; Queue AddOperation: B2; } //Main of ClassB -(void)main { //Do some work and when done call selector on ClassA above }

• how to flip Image in wpf

  - by shashank

  Hello! I recently learned how to rotate a BitmapImage using the 'TransformedBitmap' and 'RotateTransformed' classes. Now I am able to perform clockwise rotations on my images. But how do I FLIP an image? I can't find the class(es) to perform horizontal and vertical flips of a BitmapImage. Please help me figure out how to do it. For instance, if my image was a drawing that looked like a 'd', then a vertical flip would result in something like a 'q', and a horizontal flip would result in something lika a 'b'. I hope this is clear enough. Thanks in advance! Best regards, shashank

Missed something? or I cannot test -initWithNibName using Logic Tests technique. Thanks in advance for your help.

• Silverlight solution builds in VS2008 but fails with MSBuild

  - by Chris Nicola

  I have a Silverlight solution that I want to create a build script for. I have a simple script that looks like this call "c:\Program Files\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat" msbuild %CD%\V1\Incentive.sln /target:Rebuild /property:Configuration=DEBUG;WarningLevel=2 msbuild %CD%\UI\IncentiveUI.sln /target:Rebuild /property:Configuration=DEBUG;WarningLevel=2 pause However when I run this I get a failure, with some complaints about classes that are in a project with linked files: http://pastebin.com/JRE3tWfh This solution compiles fine in VS2008 so I can't figure out what the problem is. I have to guess something is wrong with the way I am using msbuild here.

• Handling inverted pixels in bitmapData and bitmap class in as3

  - by intoTHEwild

  I am using bitmapData and bitmap classes to render a mouse cursor on the display screen. The bitmapData consists of an area whose colors should be inverted according to the background color. This is a very basic thing which could be observed with text cursor(the vertical line with two small horizontals on top and bottom), when moved over the text area. I want to be able to do the same with the pixels in my bitmapData, is there a way to find out the background color effectively and invert the color values? In this process i will be redrawing the whole pixels, is there any other efficient way to do that ?

• MIDlet + BlackBerry API = verification error?

  - by Kilnr

  Hi, Is there any way to write a MIDlet, but still use BlackBerry API classes and functions (including the APIs that require code signing)? In particular, I'm trying to use Kuix (http://www.kalmeo.org/projects/kuix). A pure MIDlet + Kuix (so without BlackBerry stuff) works perfectly after I converted the jar/jad to a cod file. As soon as I add BlackBerry API-stuff (CoverageInfo.COVERAGE_DIRECT in this case) I get a verification error when trying to run the cod file: Error starting $name: Module $name has verification error 2410 at offset 9a4f What can I do to solve this?
