  • NUnit / Testdriven.Net conflicting results.

    - by panamack
    When I run this test in NUnit = Red Bar. [Test] public void ChangingValueViaPropertyDescriptorRaisesPropertyChangedNotification() { PropertyChangedEventArgs pCEventArgs = null; subjectVM.PropertyChanged += (sender, e) => { pCEventArgs = e; }; PropertyDescriptor descriptor = subjectVM.GetProperties().Find(schoolMeta.Name, false); descriptor.SetValue(null, "School's out for summer."); Assert.IsNotNull(pCEventArgs); Assert.AreEqual("School", pCEventArgs.PropertyName); } However, when I run this test from within Visual Studio with Test Driven .Net it passes. When it fails with NUnit it's because PropertyChanged is null, subjectVM is a View Model classes that inherits PropertyChanged from a base class. Am I to blame, or am I looking at a NUnit bug?

  • Do you have to install the REST starter kit in asp.net to access APIs?

    - by jonhobbs
    Hi, I'm currently trying to access a REST API for the first time using visual web developer 2008 express edition. Every article I have found says you have to install the WCF REST starter kit which is a .msi file, which would suggest that I have to install it on my machine and presumably our server too. My question is this. Is there a non installable version that I can use, e.g. just by dropping DLLs into the Bin directory and then using the classes contained. Or is there more to it than that and am I just getting very confused about how it works? Jon

    - by onurozcelik
    Hi everyone I have system that has classes derived from QGraphicsWidget. I manage derived class objects in layouts on QGraphicsScene. Now I need a compound item that contain two or more QGraphicsWidget in it and also I need to put that item inside my layout. So I choose QGraphicsItemGroup and write I class like this. class CompositeItem : public QGraphicsItemGroup,public QGraphicsLayoutItem { ... }; I only implemented sizeHint function again.

  • C# Reflection - Casting private Object field

    - by alhazen
    I have the following classes: public class MyEventArgs : EventArgs { public object State; public MyEventArgs (object state) { this.State = state; } } public class MyClass { // ... public List<string> ErrorMessages { get { return errorMessages; } } } When I raise my event, I set 'State' of the MyEventArgs object to an object of type MyClass. I'm trying to retrieve ErrorMessages by reflection in my event handler: public static void OnEventEnded(object sender, EventArgs args) { Type type = args.GetType(); FieldInfo stateInfo = type.GetField("State"); PropertyInfo errorMessagesInfo = stateInfo.FieldType.GetProperty("ErrorMessages"); object errorMessages = errorMessagesInfo.GetValue(null, null); } But this returns errorMessagesInfo as null (even though stateInfo is not null). Is it possible to retrieve ErrorMessages ? Thank you

  • Can i override an abstract method written in a parent class, with a different name in a child class?

    - by Ranhiru
    abstract class SettingSaver { public abstract void add(string Name, string Value); public abstract void remove(string SettingName); } class XMLSettings : SettingSaver { public override void add(string Name, string Value) { throw new NotImplementedException(); } public override void remove(string SettingName) { throw new NotImplementedException(); } } Is there anyway that I can change the name of the add function in XMLSettings class to addSetting but make sure it overrides the add function in the SettingSaver? I know it should be definitely overridden in derived classes but just want to know whether I can use a different name :) Thanx in advance :D

  • Multiple webservices in 1 ear/ejb project

    - by arinte
    We have a ejb project (which is in an ear) that shares quite a bit of code between 2 webservices. The classes that the webservices expose are in different packages but they have different names. For example Web service1 com.d.trunk.Response WS1.process( com.d.trunk.Input ); Web service2 com.d.fwd.Response WS2.process( com.d.fwd.Input ); So this builds fine, but when we deploy and we view the generated wsdl and the generated xsd things begin to go a bit haywire. So if we look at web service 2 it generates the wsdl and xsd as we expect. But when we look at ws 1's wsdl for some reason it includes the xsd from the ws 2 and its own xsd. And its own xsd are missing key types like the Response type. Is this an issue because we have 2 web services in 1 ejb project? Or some config issue with Netbeans 6.7.1 and glassfish v2?

  • Why is there a seemingly identical copy of the JDK 1.5 core runtime in org.osgi.foundation-1.0.0.jar?

    - by Jonathan Neufeld
    I am maintaining a web application that depends on OSGi and Maven pulls-in a jar called org.osgi-foundation-1.0.0.jar that seems to contain the same classes as part of the JDK core runtime such as: java.util.*; java.io.*; etc. and so on. This seems very strange and I have to ask why this is necessary. More-over, my web-application fails to deploy on JBoss 6 because these are "illegal package names" for a third-party library. What is the purpose of org.osgi-foundation-1.0.0.jar ? is it necessary?

  • Mysql eliminate user based on conditions

    - by Dustin
    I asked this last week over the weekend and it got buried in the archives before anyone could answer. So forgive me if you've already seen this. I teach classes and want to be able to select those students who have taken one class, but not another class. I have two tables: lessons_slots which is the table for every class such as: -------------------- -ID name slots- -1 basics 10 - -2 advanced 10 - -3 basics 10 - --------------------- The other table is class_roll, which holds enrollment info, such as: -------------------- -sID classid firstname lastname- -1 1 Jo Schmo -2 1 Person Two ... -13 2 Jo Schmo --------------------- What I want to do, I select everyone who has not had the advanced class (for example). I've tried doing SELECT * FROM lessons_slots LEFT JOIN class_roll ON lessons_slots.ID = class_roll.classid WHERE lessons_slots.name != 'advanced' But that doesn't work...All it does is eliminate that row, without eliminating the user. I want Jo Schmo, for example, to not show up in the results. Any ideas?

  • How to include simple collections in ConfigurationSection

    - by mikemanne
    Is there a way for me to include a simple array of strings, or List<string> on my custom subclass of ConfigurationSection? (Or an array or generic list of simple data objects, for that matter?) I'm becoming familiar with the new (and VERY verbose) ConfigurationSection, ConfigurationElement, and ConfigurationElementCollection classes, but I'm by no means an expert yet. It seems like ConfigurationSection should handle simple collections/lists on its own, without me having to create a custom ConfigurationElementCollection subclass for each and every one. But I haven't found any reference to this ability online.

  • Java Regex for matching quoted string with escaped quotes

    - by kayahr
    I know there are already many questions like mine but I found no answer which works in Java. So I write a new question. I have text files with content like this: key1 = "This is a \"test\" text with escapes using '\\' characters"; key2 = 'It must work with \'single\' quotes and "double" quotes'; I need a regular expression which matches the values in the double-quotes (or single-quotes). This regular expression must support the escaped quotes and escaped backslashes. The regular expression must work with Java standard Pattern/Matcher classes.

  • How to move from untyped DataSets to POCO\LINQ2SQL in legacy application

    - by artvolk
    Good day! I've a legacy application where data access layer consists of classes where queries are done using SqlConnection/SqlCommand and results are passed to upper layers wrapped in untyped DataSets/DataTable. Now I'm working on integrating this application into newer one where written in ASP.NET MVC 2 where LINQ2SQL is used for data access. I don't want to rewrite fancy logic of generating complex queries that are passed to SqlConnection/SqlCommand in LINQ2SQL (and don't have permission to do this), but I'd like to have result of these queries as strong-typed objects collection instead of untyped DataSets/DataTable. The basic idea is to wrap old data access code in a nice-looking from ASP.NET MVC "Model". What is the fast\easy way of doing this?

  • Jquery click behaviour

    - by VP
    I'm developing a menu. This menu, will change the background image when you click on a link, as almost all menus does. if i click in one link from the menu, this link backgroun will change the color. My jquery script is: $(function() { $('#menu ul li').click(function() { $('#menu ul li').removeClass("current_page_item"); $(this).addClass("current_page_item"); //return false; }); }); today, with the "return false" commented, when i click on the link under "#menu ul li" it changes the background open the new page and the background is reseted. For sure, if i uncomment the return false, the background works fine but then i cannot open any link. So its looks like after that i open a new page, it reset the classes. How can i make it persistent?

  • How can I get latency info from Android's AudioTrack class?

    - by Ryan
    I've noticed that the C++ classes underlying the AudioTrack and AudioRecord APIs in Android both have a latency() method that is not exposed via JNI. As far as I can see, the latency() method in AudioRecord still does not take into account the hardware latency (they have a TODO comment for that), but the latency() method in AudioTrack does add in the hardware latency. I absolutely need to get this latency value from AudioTrack. Is there any possible way I can do this? I don't care what kind of crazy hack is needed as long as it doesn't require a rooted phone (the resulting code must still be packaged as an app on the market).

  • .NET Assembly Diff / Compare Tool - What's available?

    - by STW
    I'd like to be able to do a code-level diff between two assemblies; the Diff plug-in for Reflector is the closest thing I've found so far, but to compare the entire assembly is a manual process requiring me to drill-down into every namespace/class/method. The other tools I've found so far appear to be limited to API-level (namespaces, classes, methods) differences--which won't cut it for what I'm looking for. Does anyone know of such a tool? My requirements (from highest to lowest) are: Be able to analyze / reflect the code content of two versions of the same assembly and report the differences Accept a folder or group of assemblies as input; quickly compare them (similar to WinMerge's folder diff's) Quick ability to determine if two assemblies are equivalent at the code level (not just the API's) Allow easy drill-down to view the differences Exporting of reports regarding the differences (Personally I like WinMerge for text diffs, so an application with a similar interface would be great)

  • Rails: simple bundler question

    - by Joern Akkermann
    Hi! I just installed the ruby-openid gem and then bundled it by entering gem 'ruby-openid', :require => 'openid' in the gemfile. Then I started bundle install and bundle lock. Everything worked fine so far. But how can I now access the classes of ruby-openid. OpenID::method won't work for me. It raises a not found error. What have I forgot or done wrong? I'm thankful for any help!

  • How to override the behavior of Spring @Autowired

    - by Mark
    Hi a little background: I am Using Spring 2.5, and specifically spring IOC and annotations. I am using @Autowired in my code (the Autowiring is done by type) and use @Component for exposing Classes to the Automatic wiring. The situation described bellow arose while i tried to test my code. now to the problem: Note: i use a different Spring Context for the Test environment. I have a class FOO which is @Autowired but in the test context i want to use a different class of the same type MockFoo (extends FOO) The Spring Setup of course fails do so automatically due to multiple options for the Dependency Injection of the FOO class (both FOO and MockFOO comply to the Type check) I am looking for a way to inject the test bean instead of the original bean. I expected Spring to allow using the Context configurion file to override a bean injection or to order Spring not to autowire a specific bean BUT All these option seem to exists only for the beans which were originally defined in the Spring Context Configuration file

  • How can I instantiate a base class and then convert it to a derived class?

    - by Eric
    I was wondering how to do this, consider the following classes public class Fruit { public string Name { get; set; } public Color Color { get; set; } } public class Apple : Fruit { public Apple() { } } How can I instantiate a new fruit but upcast to Apple, is there a way to instantiate a bunch of Fruit and make them apples with the name & color set. Do I need to manually deep copy? Of course this fails Fruit a = new Fruit(); a.Name = "FirstApple"; a.Color = Color.Red; Apple wa = a as Apple; System.Diagnostics.Debug.Print("Apple name: " + wa.Name); Do I need to pass in a Fruit to the AppleCTor and manually set the name and color( or 1-n properties) Is there an better design to do this?

  • JAXB - representing an element as a boolean member?

    - by Marcus
    We have this XML: <Summary> <ValueA>xxx</ValueA> <ValueB/> </Summary> <ValueB/> will never have any attributes or inner elements. It's a boolean type element - it exists (true) or it doesn't (false). JAXB generated a Summary class with a String valueA member, which is good. But for ValueB, JAXB generated a ValueB inner class and a corresponding member: @XmlElement(name = "ValueB") protected Summary.ValueB valueB; But what I'd like is a boolean member and no inner class: @XmlElement(name = "ValueB") protected boolean valueB; How can you do this? I'm not looking to regenerate the classes, I'd like to just make the code change manually.

  • C# / Visual Studio: production and test code placement

    - by Patrick Linskey
    Hi, In JavaLand, I'm used to creating projects that contain both production and test code. I like this practice because it simplifies testing of internal code without artificially exposing the internals in a project's published API. So far, in my experiences with C# / Visual Studio / ReSharper / NUnit, I've created separate projects (i.e., separate DLLs) for production and test code. Is this the idiom, or am I off base? If this idiomatically correct, what's the right way to deal with exposing classes and methods for test purposes? Thanks, -Patrick

  • Fluent NHibernate MappingException : could not instantiate id generator

    - by Mark Simpson
    I'm pottering around with Fluent NHibernate to try and get a simple app up and running. I'm running through this Fluent NHibernate Tutorial. Everything seems to be going fine and I've created the required classes etc. and it all builds, but when I run the test, I get an exception. Someone in the comments section of the tutorial has the same problem, but I can't find any good information on what's causing it. Any help appreciated. It's probably something trivial. Exception details: FluentNHTest.Tests.Mappings.CustomerMappingTests.ValidateMappings: FluentNHibernate.Cfg.FluentConfigurationException : An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail. ---- FluentNHibernate.Cfg.FluentConfigurationException : An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail. ---- NHibernate.MappingException : could not instantiate id generator ---- System.FormatException : Input string was not in a correct format.
