  • How do I setup NInject? (i.e.

    - by Greg
    Hi, I'm getting confused in the doco how I should be setting up Ninject. I'm seeing different ways of doing it, some v2 versus v1 confusion probably included... Question - What is the best way in my WinForms application to set things up for NInject (i.e. what are the few lines of code required). I'm assuming this would go into the MainForm Load method. In other words what code do I have to have prior to getting to: Bind<IWeapon>().To<Sword>(); I have the following code, so effectively I just want to get clarification on the setup and bind code that would be required in my MainForm.Load() to end up with a concrete Samurai instance? internal interface IWeapon { void Hit(string target); } class Sword : IWeapon { public void Hit(string target) { Console.WriteLine("Chopped {0} clean in half", target); } } class Samurai { private IWeapon _weapon; [Inject] public Samurai(IWeapon weapon) { _weapon = weapon; } public void Attack(string target) { _weapon.Hit(target); } } thanks

  • Idiomatic default sort using WCF RIA, Entity Framework 4, Silverlight 4?

    - by Duncan Bayne
    I've got two Silverlight 4.0 ComboBoxes; the second displays the children of the entity selected in the first: <ComboBox Name="cmbThings" ItemsSource="{Binding Path=Things,Mode=TwoWay}" DisplayMemberPath="Name" SelectionChanged="CmbThingsSelectionChanged" /> <ComboBox Name="cmbChildThings" ItemsSource="{Binding Path=SelectedThing.ChildThings,Mode=TwoWay}" DisplayMemberPath="Name" /> The code behind the view provides a (simple, hacky) way to databind those ComboBoxes, by loading Entity Framework 4.0 entities through a WCF RIA service: public EntitySet<Thing> Things { get; private set; } public Thing SelectedThing { get; private set; } protected override void OnNavigatedTo(NavigationEventArgs e) { var context = new SortingDomainContext(); context.Load(context.GetThingsQuery()); context.Load(context.GetChildThingsQuery()); Things = context.Things; DataContext = this; } private void CmbThingsSelectionChanged(object sender, SelectionChangedEventArgs e) { SelectedThing = (Thing) cmbThings.SelectedItem; if (PropertyChanged != null) { PropertyChanged.Invoke(this, new PropertyChangedEventArgs("SelectedThing")); } } public event PropertyChangedEventHandler PropertyChanged; What I'd like to do is have both combo boxes sort their contents alphabetically, and I'd like to specify that behaviour in the XAML if at all possible. Could someone please tell me what is the idiomatic way of doing this with the SL4 / EF4 / WCF RIA technology stack?

    - by IB
    Hello I have a Biztalk 2006 R2 project (used with ESB Guidance 1) I am calling from orchstration to a static method in c# code, this method uses a class to load a file data into xlang message body at part 0 When i pass filepath which doesnt exists the inside class catch the exception but dont throw it up (in the static method there is a catch block and in the orchstration there is the real handling of the exception) The static method is : public static XLANGMessage LoadFileIntoMessage(XLANGMessage message, string filePath,Encoding encoding) { try { IStreamFactory sf = new FileStreamFactory(filePath,encoding); message[0].LoadFrom(sf); return message; } catch (Exception ex) { throw ex; } } The Class which load the file stream is : private class FileStreamFactory : IStreamFactory { string _fname; Encoding _encoding; public FileStreamFactory(string fname,Encoding encoding) { _fname = fname; _encoding = encoding; } public Stream CreateStream() { try { StreamReader sr; sr = new StreamReader ( _fname, _encoding ); return sr.BaseStream; } catch (Exception ex) { throw ex; } } } I call the static method from the orchstration and expect to catch the exception in my orchstration after the class and the emthod gets it

  • use startActivityForResult from non-activity

    - by rayman
    Hi, I have MainActivity which is an Activity and other class(which is a simple java class), we`ll call it "SimpleClass". now i want to run from that class the command startActivityForResult. now i though that i could pass that class(SimpleClass), only MainActivity's context, problem is that, u cant run context.startActivityForResult(...); so the only way making SimpleClass to use 'startActivityForResult; is to pass the reference of MainActivity as an Activity variable to the SimpleClass something like that: inside the MainActivity class i create the instance of SimpleClass this way: SimpleClass simpleClass=new SimpleClass(MainActivity.this); now this is how SimpleClass looks like: public Class SimpleClass { Activity myMainActivity; public SimpleClass(Activity mainActivity) { super(); this.myMainActivity=mainActivity; } .... } public void someMethod(...) { myMainActivity.startActivityForResult(...); } now its working, but isnt a proper way of doing this? I`am afraid i could have some memory leaks in the future. thanks. ray.

  • Calling a method within Portlet when submitting form

    - by Roland
    I have a Portlet that contains a form. Now what I want to achieve is the following. 1) A Porlet containing a form is called within a page via <?php $this->widget('form'); ?> 2) The user fills in this form and clicks on submit "The submit button should be an ajax button" 3) When submit has been pressed the form should call a method within the form portlet class and the form should be replaced with a Thank you message. 4) I only want the current view in the portlet replaced with another view. My portlet class looks like this Yii::import('zii.widgets.CPortlet'); class Polls extends CPortlet{ public $usr_id=''; public function init(){ $cs = Yii::app()->clientScript; $cs->registerCoreScript('jquery'); parent::init(); } protected function renderContent(){ $this->render('form'); } public function update(){ $this->render('thankyou'); } } } Any advise, help would be highly appreciated.

  • WCF Service invalid with Silverlight

    - by Echilon
    I'm trying to get WCF working with Silverlight. I'm a total beginner to WCF but have written asmx services in the past. For some reason when I uncomment more than one method in my service Silverlight refuses to let me use it, saying it is invalid. My code is below if anyone could help. I'm using the Entity Framework if that makes a difference. [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class MessageService {//: IMessageService { /// <summary> /// Sends a new message. /// </summary> /// <param name="recipientUsername">The recipient username.</param> /// <param name="subject">The subject.</param> /// <param name="messageBody">The message body.</param> [OperationContract] public void SendMessageByDetails(string recipientUsername, string subject, string messageBody) { MessageDAL.SendMessage(recipientUsername, subject, messageBody); } /// <summary> /// Sends a new message. /// </summary> /// <param name="msg">The message to send.</param> [OperationContract] public void SendMessage(Message msg) { MessageDAL.SendMessage(msg); } }

  • NHibernate stored procedure problem

    - by Calvin
    I'm having a hard time trying to get my stored procedure works with NHibernate. The data returned from the SP does not correspond to any database table. This is my mapping file: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="DomainModel" namespace="DomainModel.Entities"> <sql-query name="DoSomething"> <return class="SomeClass"> <return-property name="ID" column="ID"/> </return> exec [dbo].[sp_doSomething] </sql-query> </hibernate-mapping> Here is my domain class: namespace DomainModel.Entities { public class SomeClass { public SomeClass() { } public virtual Guid ID { get; set; } } } When I run the code, it fails with Exception Details: NHibernate.HibernateException: Errors in named queries: {DoSomething} at line 80 Line 78: config.Configure(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "NHibernate.config")); Line 79: Line 80: g_sessionFactory = config.BuildSessionFactory(); When I debug into NHibernate code, it seems that SomeClass is not added to the persister dictionary because there isn't a class mapping (only sql-query) defined in hbm.xml. And later on in CheckNamedQueries function, it is not able to find the persistor for SomeClass. I've checked all the obvious things (e.g. make hbm as an embedded resource) and my code isn't too much different from other samples I found on the web, but somehow I just can't get it working. Any idea how I can resolve this issue?

  • How do I unit test controllers for an asp.net mvc site that uses StructureMap and NHibernate?

    - by Jim Geurts
    I have an asp.net mvc2 application that is using StructureMap 2.6 and NHibernate 3.x. I would like to add unit tests to the application but am sort of at a loss for how to accomplish it. Say I have a basic controller called Posts that has an action called Index. The controller looks something like: public class PostsController : Controller { private readonly IPostService _postService; public PostsController(IPostService postService) { _postService = postService; } public ActionResult Index() { return View(_postService.QueryOver<Post>().Future()); } } If I wanted to create an nunit test that would verify that the index action is returning all of the posts, how do I go about that? If mocking is recommended, do you just assume that interaction with the database will work? Sorry for asking such a broad question, but my web searches haven't turned up anything decent for how to unit test asp.net mvc actions that use StructureMap (or any other IOC) and NHibernate. btw, if you don't like that I return a QueryOver object from my post service, pretend it is an IQueryable object. I'm using it essentially in the same way.

    How to shuffle the elements in the pairs? The program below, generate all possible pairs and later shuffle the pairs. e.g. possible pairs before shuffle is ab,ac,ae,af..etc shuffled to ac,ae,af,ab...etc How to make it not only shuffled in pairs but within the elements in the pair itself? e.g. instead of ab, ac, how can I make ba, ac ? String[] pictureFile = {"a.jpg","b.jpg","c.jpg","d.jpg","e.jpg","f.jpg","g.jpg"}; List <String> pic1= Arrays.asList(pictureFile); ... ListGenerator pic2= new ListGenerator(pic1); ArrayList<ArrayList<Integer>> pic2= new ArrayList<ArrayList<Integer>>(); public class ListGenerator { public ListGenerator(List<String> pic1) { int size = pic1.size(); // create a list of all possible combinations for(int i = 0 ; i < size ; i++) { for(int j = (i+1) ; j < size ; j++) { ArrayList<Integer> temp = new ArrayList<Integer>(); temp.add(i); temp.add(j); pic2.add(temp); } } Collections.shuffle(pic2); } //This method return the shuffled list public ArrayList<ArrayList<Integer>> getList() { return pic2; } }

  • When is onBind or onCreate called in an android service browser plugin?

    - by anselm
    I have adapted the example plugin of the android source and the browser recognises the plugin without any problem. Here is an extract of AndroidManifest.xml: <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true"> <service android:name="com.domain.plugin.PluginService"> <intent-filter> <action android:name="android.webkit.PLUGIN" /> </intent-filter> </service> </application> <uses-sdk android:minSdkVersion="7" /> <uses-permission android:name="android.webkit.permission.PLUGIN"></uses-permission> The actual Service class looks like so: public class PluginService extends Service { @Override public IBinder onBind(Intent arg0) { Log.d("PluginService", "onBind"); return null; } @Override public void onCreate() { Log.d("PluginService", "onCreate"); // TODO Auto-generated method stub super.onCreate(); AssetInstaller.getInstance(this).installAssets("/data/data/com.domain.plugin"); } } The AssetInstaller code is supposed to extract some files required by the actual plugin into the /data/data/com.domain.plugin directory, however wether onBind nor onCreate are called. But I get lot's of debug trace of the actual libnpplugin.so file I'm using. So the puzzle is when and under what circumstance is the Service bound or created in case of a browser plugin. As things look the service seems to be a dummy service. Having said that, is there another intent that can be executed at installation time probably? The only solution I see right now is installing the needed files from the native plugin code instead. Any ideas? I know this is quite a tricky question ;)

  • Sensible unit test possible?

    - by nkr1pt
    Could a sensible unit test be written for this code which extracts a rar archive by delegating it to a capable tool on the host system if one exists? I can write a test case based on the fact that my machine runs linux and the unrar tool is installed, but if another developer who runs windows would check out the code the test would fail, although there would be nothing wrong with the extractor code. I need to find a way to write a meaningful test which is not binded to the system and unrar tool installed. How would you tackle this? public class Extractor { private EventBus eventBus; private ExtractCommand[] linuxExtractCommands = new ExtractCommand[]{new LinuxUnrarCommand()}; private ExtractCommand[] windowsExtractCommands = new ExtractCommand[]{}; private ExtractCommand[] macExtractCommands = new ExtractCommand[]{}; @Inject public Extractor(EventBus eventBus) { this.eventBus = eventBus; } public boolean extract(DownloadCandidate downloadCandidate) { for (ExtractCommand command : getSystemSpecificExtractCommands()) { if (command.extract(downloadCandidate)) { eventBus.fireEvent(this, new ExtractCompletedEvent()); return true; } } eventBus.fireEvent(this, new ExtractFailedEvent()); return false; } private ExtractCommand[] getSystemSpecificExtractCommands() { String os = System.getProperty("os.name"); if (Pattern.compile("linux", Pattern.CASE_INSENSITIVE).matcher(os).find()) { return linuxExtractCommands; } else if (Pattern.compile("windows", Pattern.CASE_INSENSITIVE).matcher(os).find()) { return windowsExtractCommands; } else if (Pattern.compile("mac os x", Pattern.CASE_INSENSITIVE).matcher(os).find()) { return macExtractCommands; } return null; } }

  • Can't get recursive function to work in Java

    - by Ahmed Salah
    I read docs about java recorsion and I thought I have understood it, but when I try to use it in the following example, it does not work as expected. I a class account, which has amount and can have forther subAccount. I would have implemented one method getSum, which has to return the summ of the amount of the account and amount of all of its subaccount. In the following code, the call of the method getSumm() should return 550, but it behaves strange. can somebody help please? public class Balance{ ArrayList<Balance> subAccounts = new ArrayList<Balance>(); String accountID = null; Double amount = null; double result=0; public double getSum(ArrayList<Balance> subAccounts){ if(subAccounts !=null && subAccounts.size()>0){ for (int i = 0; i < subAccounts.size(); i++) { result = result + getSum(subAccounts.get(i).subAccounts); } } else { return amount; } return result; } public static void main(String[] args) { Balance bs1 = new Balance(); Balance bs2 = new Balance(); Balance bs3 = new Balance(); bs1.amount=100.0; bs2.amount=150.0; bs3.amount=300.0; ArrayList<Balance> subAccounts1 = new ArrayList<Balance>(); bs2.subAccounts=null; bs3.subAccounts=null; subAccounts1.add(bs2); subAccounts1.add(bs3); bs1.subAccounts=subAccounts1; double sum= bs1.getSum(subAccounts1); System.out.println(sum); } }

  • Java method keyword "final" and its use

    - by Lukas Eder
    When I create complex type hierarchies (several levels, several types per level), I like to use the final keyword on methods implementing some interface declaration. An example: interface Garble { int zork(); } interface Gnarf extends Garble { /** * This is the same as calling {@link #zblah(0)} */ int zblah(); int zblah(int defaultZblah); } And then abstract class AbstractGarble implements Garble { @Override public final int zork() { ... } } abstract class AbstractGnarf extends AbstractGarble implements Gnarf { // Here I absolutely want to fix the default behaviour of zblah // No Gnarf shouldn't be allowed to set 1 as the default, for instance @Override public final int zblah() { return zblah(0); } // This method is not implemented here, but in a subclass @Override public abstract int zblah(int defaultZblah); } I do this for several reasons: It helps me develop the type hierarchy. When I add a class to the hierarchy, it is very clear, what methods I have to implement, and what methods I may not override (in case I forgot the details about the hierarchy) I think overriding concrete stuff is bad according to design principles and patterns, such as the template method pattern. I don't want other developers or my users do it. So the final keyword works perfectly for me. My question is: Why is it used so rarely in the wild? Can you show me some examples / reasons where final (in a similar case to mine) would be very bad?

  • NHibernate Child items query using Parent Id

    - by thorkia
    So I have a set up similar to this questions: Parent Child Setup Everything works great when saving the parent and the children. However, I seem to have a problem when selecting the children. I can't seem to get all the children with a specific parent. This fails with: NHibernate.QueryException: could not resolve property: ParentEntity_id of: Test.Data.ChildEntity Here is my code: public IEnumerable<ChildEntity> GetByParent(ParentEntity parent) { using (ISession session = OrmHelper.OpenSession()) { return session.CreateCriteria<ChildEntity>().Add(Restrictions.Eq("ParentEntity_id ", parent.Id)).List<ChildEntity>(); } } Any help in building a proper function to get all the items would be appreciated. Oh, I am using Fluent NHibernate to construct the mappings - version 1 RTM and NHibernate 2.1.2 GA If you need more information, let me know. As per you request, my fluent mappings: public ParentEntityMap() { Id(x => x.Id); Map(x => x.Name); Map(x => x.Code).UniqueKey("ukCode"); HasMany(x => x.ChildEntity).LazyLoad() .Inverse().Cascade.SaveUpdate(); } public ChildEntityMap() { Id(x => x.Id); Map(x => x.Amount); Map(x => x.LogTime); References(x => x.ParentEntity); } That maps to the following 2 tables: CREATE TABLE "ParentEntity" ( Id integer, Name TEXT, Code TEXT, primary key (Id), unique (Code) ) CREATE TABLE "ChildEntity" ( Id integer, Amount NUMERIC, LogTime DATETIME, ParentEntity_id INTEGER, primary key (Id) ) The data store in SQLite.

  • Axis2 Webservice -> php

    - by Peter Hagström
    Hi! If I have understood Axis2 correct i can construct a WebService and then access it with any SOAP compatible client. I have a java class with a couple of methods that I have written in Eclipse, and then automatically constructed a service with the Axis2 plugin from WTP. This is the methods of my class. public int test(int i){ return i+2; } public Car CarTest(int speed){ return new Car("Biltest", speed); } public CarFactoryAdapter getCarFactory(){ carFact.getCars().add(new Car("Bmw", 250)); carFact.getCars().add(new Car("seat", 350)); carFact.getCars().add(new Car("saab", 150)); carFact.getCars().add(new Car("volv", 50)); return new CarFactoryAdapter(carFact); } The code seems to work when I try it with soapUI and the Axis2-web interface has recognized the methods of my service. But when Iam trying the methods that receives parameters with PHP´s built in soapClient i get a Unknown exception. The getCarFactory methods works at least as expected, but it seems kind of crippled if I can´t send parameters. Example of non working method invocation. ini_set('soap.wsdl_cache_ttl',0); $client = new SoapClient("http://192.168.128.162:8080/ComplexWebService/services/CarService?wsdl", array('soap_version' => SOAP_1_2, 'trace' => 1)); $ar['i'] = (int)100; print_r($client->__soapCall("test",$ar)); I need to make sure that the SOA framework i choose will be able to comunicate with many platforms, there will be clients in at least PHP and Java, but it would be good if it will work in for example .NET to.

  • Debugging a HTTP Handler from Visual Studio

    - by O.O.
    I am trying to debug a HTTP Handler in Visual Studio and the break point is not getting hit. Does anyone have an idea on how to go about debugging HTTP Handlers in Visual Studio? I am using VS 2010 Premium, .NET 4.0 on a Windows 7 machine. In my Web Application I have a HTTP Handler in /HTTPHandler/TrackingHandler.cs The following is in my web config file: <system.webServer> <handlers> <add name="TrackingHandler" path="/tx/*" verb="*" type="ProjectNamespace.TrackingHandler" resourceType="Unspecified" preCondition="integratedMode" /> </handlers> </system.webServer> My HTTP Handler looks like below namespace ProjectNamespace { public class TrackingHandler : IHttpHandler { public bool IsReusable { get { return true; } } public void ProcessRequest(HttpContext context) { //Breakpoint on the very first line below string tracker = Path.GetFileName(context.Request.PhysicalPath); ....... } } } I start my Web Application using any random page in Visual Studio Debug using the builtin Web Server. I then maually edit the URL to point to the /tx/ directory and some random string after it. For e.g. my current URL looks like http://localhost:53699/tx/sdfs. I thought this should pull up the breakpoint on the first line of ProcessRequest() but it does not. I’d be grateful for any ideas. O. O.

  • Is this GetEnumAsStrings<T>() method reinventing the wheel?

    - by Edward Tanguay
    I have a number of enums and need to get them as List<string> objects in order to enumerate through them and hence made the GetEnumAsStrings<T>() method. But it seems to me there would be an easier way. Is there not a built-in method to get an enum like this into a List<string>? using System; using System.Collections.Generic; namespace TestEnumForeach2312 { class Program { static void Main(string[] args) { List<string> testModes = StringHelpers.GetEnumAsStrings<TestModes>(); testModes.ForEach(s => Console.WriteLine(s)); Console.ReadLine(); } } public static class StringHelpers { public static List<string> GetEnumAsStrings<T>() { List<string> enumNames = new List<string>(); foreach (T item in Enum.GetValues(typeof(TestModes))) { enumNames.Add(item.ToString()); } return enumNames; } } public enum TestModes { Test, Show, Wait, Stop } }

  • Best Practice With JFrame Constructors?

    - by David Barry
    In both my Java classes, and the books we used in them laying out a GUI with code heavily involved the constructor of the JFrame. The standard technique in the books seems to be to initialize all components and add them to the JFrame in the constructor, and add anonymous event handlers to handle events where needed, and this is what has been advocated in my class. This seems to be pretty easy to understand, and easy to work with when creating a very simple GUI, but seems to quickly get ugly and cumbersome when making anything other than a very simple gui. Here is a small code sample of what I'm describing: public class FooFrame extends JFrame { JLabel inputLabel; JTextField inputField; JButton fooBtn; JPanel fooPanel; public FooFrame() { super("Foo"); fooPanel = new JPanel(); fooPanel.setLayout(new FlowLayout()); inputLabel = new JLabel("Input stuff"); fooPanel.add(inputLabel); inputField = new JTextField(20); fooPanel.add(inputField); fooBtn = new JButton("Do Foo"); fooBtn.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { //handle event } }); fooPanel.add(fooBtn); add(fooPanel, BorderLayout.CENTER); } } Is this type of use of the constructor the best way to code a Swing application in java? If so, what techniques can I use to make sure this type of constructor is organized and maintainable? If not, what is the recommended way to approach putting together a JFrame in java?
