• Jetty 7 + MySQL Config [java.lang.ClassNotFoundException: org.mortbay.jetty.webapp.WebAppContext]

  I've been trying to get a c3p0 db connection pool configured for Jetty, but I keep getting a ClassNotFoundException: 2010-03-14 19:32:12.028:WARN::Failed startup of context WebAppContext@fccada@fccada/phpMyAdmin,file:/usr/local/jetty/webapps/phpMyAdmin/,file:/usr/local/jetty/webapps/phpMyAdmin/ java.lang.ClassNotFoundException: org.mortbay.jetty.webapp.WebAppContext at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at org.eclipse.jetty.webapp.WebAppClassLoader.loadClass(WebAppClassLoader.java:313) at org.eclipse.jetty.webapp.WebAppClassLoader.loadClass(WebAppClassLoader.java:266) at org.eclipse.jetty.util.Loader.loadClass(Loader.java:90) at org.eclipse.jetty.xml.XmlConfiguration.nodeClass(XmlConfiguration.java:224) at org.eclipse.jetty.xml.XmlConfiguration.configure(XmlConfiguration.java:187) at org.eclipse.jetty.webapp.JettyWebXmlConfiguration.configure(JettyWebXmlConfiguration.java:77) at org.eclipse.jetty.webapp.WebAppContext.startContext(WebAppContext.java:975) at org.eclipse.jetty.server.handler.ContextHandler.doStart(ContextHandler.java:586) at org.eclipse.jetty.webapp.WebAppContext.doStart(WebAppContext.java:349) at org.eclipse.jetty.util.component.AbstractLifeCycle.start(AbstractLifeCycle.java:55) at org.eclipse.jetty.server.handler.HandlerCollection.doStart(HandlerCollection.java:165) at org.eclipse.jetty.server.handler.ContextHandlerCollection.doStart(ContextHandlerCollection.java:162) at org.eclipse.jetty.util.component.AbstractLifeCycle.start(AbstractLifeCycle.java:55) at org.eclipse.jetty.server.handler.HandlerCollection.doStart(HandlerCollection.java:165) at org.eclipse.jetty.util.component.AbstractLifeCycle.start(AbstractLifeCycle.java:55) at org.eclipse.jetty.server.handler.HandlerWrapper.doStart(HandlerWrapper.java:92) at org.eclipse.jetty.server.Server.doStart(Server.java:228) at org.eclipse.jetty.util.component.AbstractLifeCycle.start(AbstractLifeCycle.java:55) at org.eclipse.jetty.xml.XmlConfiguration$1.run(XmlConfiguration.java:990) at java.security.AccessController.doPrivileged(Native Method) at org.eclipse.jetty.xml.XmlConfiguration.main(XmlConfiguration.java:955) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.jetty.start.Main.invokeMain(Main.java:394) at org.eclipse.jetty.start.Main.start(Main.java:546) at org.eclipse.jetty.start.Main.parseCommandLine(Main.java:208) at org.eclipse.jetty.start.Main.main(Main.java:75) I'm new to Jetty and I want to ultimately get phpMyAdmin and WordPress to run on it through Quercus and a JDBC connection.

Someone please tell me what is wrong with my configuration. I'm sick of digging through Jetty's crappy documentation.

• WPF ComboBox Binding to non string object

  - by Mike L

  I'm using MVVM (MVVM Light Toolkit) and have a property on the view model which exposes a list of objects. The objects contain two properties, both strings, which correlate to an abbreviation and a description. I want the ComboBox to expose the pairing as "abbreviation - description". If I use a data template, it does this easily. I have another property on the view model which represents the object that should display as selected -- the chosen item in the ComboBox. I'm binding the ItemsSource to the list, as it represents the universe of available selections, and am trying to bind the SelectedItem to this object. I'm killing myself trying to figure out why I can't get it to work, and feeling more like a fraud by the hour. In trying to learn why this works, I created the same approach with just a list of strings, and a selected string. This works perfectly. So, it clearly has something to do with the typing... perhaps something in choosing equality? Or perhaps it has to do with the data template? Here is the XAML: <Window x:Class="MvvmLight1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="300" Width="300" DataContext="{Binding Main, Source={StaticResource Locator}}"> <Window.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Skins/MainSkin.xaml" /> </ResourceDictionary.MergedDictionaries> <DataTemplate x:Key="DataTemplate1"> <StackPanel Orientation="Horizontal"> <TextBlock TextWrapping="Wrap" Text="{Binding CourtCode}"/> <TextBlock TextWrapping="Wrap" Text=" - "/> <TextBlock TextWrapping="Wrap" Text="{Binding CourtDescription}"/> </StackPanel> </DataTemplate> </ResourceDictionary> </Window.Resources> <Grid x:Name="LayoutRoot"> <ComboBox x:Name="cmbAbbrevDescriptions" Height="35" Margin="25,75,25,25" VerticalAlignment="Top" ItemsSource="{Binding Codes}" ItemTemplate="{DynamicResource DataTemplate1}" SelectedItem="{Binding selectedCode}" /> <ComboBox x:Name="cmbStrings" Height="35" Margin="25" VerticalAlignment="Top" ItemsSource="{Binding strs}" SelectedItem="{Binding selectedStr}"/> </Grid> </Window> And, if helpful, here is the ViewModel: using GalaSoft.MvvmLight; using MvvmLight1.Model; using System.Collections.Generic; namespace MvvmLight1.ViewModel { public class MainViewModel : ViewModelBase { public const string CodesPropertyName = "Codes"; private List<Court> _codes = null; public List<Court> Codes { get { return _codes; } set { if (_codes == value) { return; } var oldValue = _codes; _codes = value; // Update bindings and broadcast change using GalaSoft.Utility.Messenging RaisePropertyChanged(CodesPropertyName, oldValue, value, true); } } public const string selectedCodePropertyName = "selectedCode"; private Court _selectedCode = null; public Court selectedCode { get { return _selectedCode; } set { if (_selectedCode == value) { return; } var oldValue = _selectedCode; _selectedCode = value; // Update bindings and broadcast change using GalaSoft.Utility.Messenging RaisePropertyChanged(selectedCodePropertyName, oldValue, value, true); } } public const string strsPropertyName = "strs"; private List<string> _strs = null; public List<string> strs { get { return _strs; } set { if (_strs == value) { return; } var oldValue = _strs; _strs = value; // Update bindings and broadcast change using GalaSoft.Utility.Messenging RaisePropertyChanged(strsPropertyName, oldValue, value, true); } } public const string selectedStrPropertyName = "selectedStr"; private string _selectedStr = ""; public string selectedStr { get { return _selectedStr; } set { if (_selectedStr == value) { return; } var oldValue = _selectedStr; _selectedStr = value; // Update bindings and broadcast change using GalaSoft.Utility.Messenging RaisePropertyChanged(selectedStrPropertyName, oldValue, value, true); } } /// <summary> /// Initializes a new instance of the MainViewModel class. /// </summary> public MainViewModel() { Codes = new List<Court>(); Court code1 = new Court(); code1.CourtCode = "ABC"; code1.CourtDescription = "A Court"; Court code2 = new Court(); code2.CourtCode = "DEF"; code2.CourtDescription = "Second Court"; Codes.Add(code1); Codes.Add(code2); Court code3 = new Court(); code3.CourtCode = "DEF"; code3.CourtDescription = "Second Court"; selectedCode = code3; selectedStr = "Hello"; strs = new List<string>(); strs.Add("Goodbye"); strs.Add("Hello"); strs.Add("Ciao"); } } } And here is the ridiculously trivial class that is being exposed: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace MvvmLight1.Model { public class Court { public string CourtCode { get; set; } public string CourtDescription { get; set; } } } Thanks!

• JSF Portlets in Liferay on JBoss

  - by JBirch

  I'm currently looking at working with and deploying JSF portlets into Liferay 6.0.5, sitting on JBoss 5.1.0. I ran into a lot of trouble trying to port some JSF-y/Seam-y/EJB-y stuff I had lying around, so I thought I'd start simple and work my way up. I could generate generic portlets using the NetBeans Maven archetype for Liferay portlets absolutely fine, but it's rather irrelevant because I wanted JSF portlets I took an example JSF portlet from http://www.liferay.com/downloads/liferay-portal/community-plugins/-/software_catalog/products/5546866 and attempted to deploy into a clean, vanilla installation of Liferay 6.0.5/JBoss 5.1.0 to no avail. The log messages are reproduced at the end of this. This particular example was actually tested for GlassFish and Tomcat, so it's not particularly helpful considering I'm deplying into JBoss. I tried ripping it apart and removing the jsf implementation contained within as there is a jsf implementation shipped with JBoss (Mojarra 1.2_12, in this case). 03:16:17,173 INFO [PortletAutoDeployListener] Copying portlets for /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/deploy/richfaces-sun-jsf1.2-facelets-portlet-1.2.war Expanding: /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/deploy/richfaces-sun-jsf1.2-facelets-portlet-1.2.war into /tmp/20110201031617188 Copying 1 file to /tmp/20110201031617188/WEB-INF Copying 1 file to /tmp/20110201031617188/WEB-INF/classes Copying 1 file to /tmp/20110201031617188/WEB-INF/classes Copying 47 files to /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/jboss-5.1.0/server/default/deploy/richfaces-sun-jsf1.2-facelets-portlet.war Copying 1 file to /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/jboss-5.1.0/server/default/deploy/richfaces-sun-jsf1.2-facelets-portlet.war Deleting directory /tmp/20110201031617188 03:16:20,075 INFO [PortletAutoDeployListener] Portlets for /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/deploy/richfaces-sun-jsf1.2-facelets-portlet-1.2.war copied successfully.

• Load application context problem in Maven managed spring-test TestNg

  - by joejax

  I try to setup a project with spring-test using TestNg in Maven. The code is like: @ContextConfiguration(locations={"test-context.xml"}) public class AppTest extends AbstractTestNGSpringContextTests { @Test public void testApp() { assert true; } } A test-context.xml simply defined a bean: <bean id="app" class="org.sonatype.mavenbook.simple.App"/> I got error for Failed to load ApplicationContext when running mvn test from command line, seems it cannot find the test-context.xml file; however, I can get it run correctly inside Eclipse (with TestNg plugin). So, test-context.xml is under src/test/resources/, how do I indicate this in the pom.xml so that 'mvn test' command will work? Thanks, UPDATE: Thanks for the reply. Cannot load context file error was caused by I moved the file arround in different location since I though the classpath was the problem. Now I found the context file seems loaded from the Maven output, but the test is failed: Running TestSuite May 25, 2010 9:55:13 AM org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions INFO: Loading XML bean definitions from class path resource [test-context.xml] May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext prepareRefresh INFO: Refreshing org.springframework.context.support.GenericApplicationContext@171bbc9: display name [org.springframework.context.support.GenericApplicationContext@171bbc9]; startup date [Tue May 25 09:55:13 PDT 2010]; root of context hierarchy May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext obtainFreshBeanFactory INFO: Bean factory for application context [org.springframework.context.support.GenericApplicationContext@171bbc9]: org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99 May 25, 2010 9:55:13 AM org.springframework.beans.factory.support.DefaultListableBeanFactory preInstantiateSingletons INFO: Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99: defining beans [app,org.springframework.context.annotation.internalCommonAnnotationProcessor,org.springframework.context.annotation.internalAutowiredAnnotationProcessor,org.springframework.context.annotation.internalRequiredAnnotationProcessor]; root of factory hierarchy Tests run: 3, Failures: 2, Errors: 0, Skipped: 1, Time elapsed: 0.63 sec If I use spring-test version 3.0.2.RELEASE, the error becomes: org.springframework.test.context.testng.AbstractTestNGSpringContextTests.springTestContextPrepareTestInstance() is depending on nonexistent method null Here is the structure of the project: simple |-- pom.xml `-- src |-- main | `-- java `-- test |-- java `-- resources |-- test-context.xml `-- testng.xml testng.xml: <suite name="Suite" parallel="false"> <test name="Test"> <classes> <class name="org.sonatype.mavenbook.simple.AppTest"/> </classes> </test> </suite> test-context.xml: <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd" default-lazy-init="true"> <bean id="app" class="org.sonatype.mavenbook.simple.App"/> </beans> In the pom.xml, I add testng, spring, and spring-test artifacts, and plugin: <dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>5.1</version> <classifier>jdk15</classifier> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> <version>2.5.6</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>2.5.6</version> <scope>test</scope> </dependency> <build> <finalName>simple</finalName> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <configuration> <suiteXmlFiles> <suiteXmlFile>src/test/resources/testng.xml</suiteXmlFile> </suiteXmlFiles> </configuration> </plugin> </plugins> Basically, I replaced 'A Simple Maven Project' Junit with TestNg, hope it works.

• Adding Volcanos and Options - Earthquake Locator, part 2

  - by Bobby Diaz

  Since volcanos are often associated with earthquakes, and vice versa, I decided to show recent volcanic activity on the Earthquake Locator map.  I am pulling the data from a website created for a joint project between the Smithsonian's Global Volcanism Program and the US Geological Survey's Volcano Hazards Program, found here.  They provide a Weekly Volcanic Activity Report as an RSS feed.   I started implementing this new functionality by creating a new Volcano entity in the domain model and adding the following to the EarthquakeService class (I also factored out the common reading/parsing helper methods to a separate FeedReader class that can be used by multiple domain service classes):           private static readonly string VolcanoFeedUrl =             ConfigurationManager.AppSettings["VolcanoFeedUrl"];           /// <summary>         /// Gets the volcano data for the previous week.         /// </summary>         /// <returns>A queryable collection of <see cref="Volcano"/> objects.</returns>         public IQueryable<Volcano> GetVolcanos()         {             var feed = FeedReader.Load(VolcanoFeedUrl);             var list = new List<Volcano>();               if ( feed != null )             {                 foreach ( var item in feed.Items )                 {                     var quake = CreateVolcano(item);                     if ( quake != null )                     {                         list.Add(quake);                     }                 }             }               return list.AsQueryable();         }           /// <summary>         /// Creates a <see cref="Volcano"/> object for each item in the RSS feed.         /// </summary>         /// <param name="item">The RSS item.</param>         /// <returns></returns>         private Volcano CreateVolcano(SyndicationItem item)         {             Volcano volcano = null;             string title = item.Title.Text;             string desc = item.Summary.Text;             double? latitude = null;             double? longitude = null;               FeedReader.GetGeoRssPoint(item, out latitude, out longitude);               if ( !String.IsNullOrEmpty(title) )             {                 title = title.Substring(0, title.IndexOf('-'));             }             if ( !String.IsNullOrEmpty(desc) )             {                 desc = String.Join("\n\n", desc                         .Replace("<p>", "")                         .Split(                             new string[] { "</p>" },                             StringSplitOptions.RemoveEmptyEntries)                         .Select(s => s.Trim())                         .ToArray())                         .Trim();             }               if ( latitude != null && longitude != null )             {                 volcano = new Volcano()                 {                     Id = item.Id,                     Title = title,                     Description = desc,                     Url = item.Links.Select(l => l.Uri.OriginalString).FirstOrDefault(),                     Latitude = latitude.GetValueOrDefault(),                     Longitude = longitude.GetValueOrDefault()                 };             }               return volcano;         } I then added the corresponding LoadVolcanos() method and Volcanos collection to the EarthquakeViewModel class in much the same way I did with the Earthquakes in my previous article in this series. Now that I am starting to add more information to the map, I wanted to give the user some options as to what is displayed and allowing them to choose what gets turned off.  I have updated the MainPage.xaml to look like this:   <UserControl x:Class="EarthquakeLocator.MainPage"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:d="http://schemas.microsoft.com/expression/blend/2008"     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"     xmlns:basic="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"     xmlns:bing="clr-namespace:Microsoft.Maps.MapControl;assembly=Microsoft.Maps.MapControl"     xmlns:vm="clr-namespace:EarthquakeLocator.ViewModel"     mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480" >     <UserControl.Resources>         <DataTemplate x:Key="EarthquakeTemplate">             <Ellipse Fill="Red" Stroke="Black" StrokeThickness="1"                      Width="{Binding Size}" Height="{Binding Size}"                      bing:MapLayer.Position="{Binding Location}"                      bing:MapLayer.PositionOrigin="Center">                 <ToolTipService.ToolTip>                     <StackPanel>                         <TextBlock Text="{Binding Title}" FontSize="14" FontWeight="Bold" />                         <TextBlock Text="{Binding UtcTime}" />                         <TextBlock Text="{Binding LocalTime}" />                         <TextBlock Text="{Binding DepthDesc}" />                     </StackPanel>                 </ToolTipService.ToolTip>             </Ellipse>         </DataTemplate>           <DataTemplate x:Key="VolcanoTemplate">             <Polygon Fill="Gold" Stroke="Black" StrokeThickness="1" Points="0,10 5,0 10,10"                      bing:MapLayer.Position="{Binding Location}"                      bing:MapLayer.PositionOrigin="Center"                      MouseLeftButtonUp="Volcano_MouseLeftButtonUp">                 <ToolTipService.ToolTip>                     <StackPanel>                         <TextBlock Text="{Binding Title}" FontSize="14" FontWeight="Bold" />                         <TextBlock Text="Click icon for more information..." />                     </StackPanel>                 </ToolTipService.ToolTip>             </Polygon>         </DataTemplate>     </UserControl.Resources>       <UserControl.DataContext>         <vm:EarthquakeViewModel AutoLoadData="True" />     </UserControl.DataContext>       <Grid x:Name="LayoutRoot">           <bing:Map x:Name="map" CredentialsProvider="--Your-Bing-Maps-Key--"                   Center="{Binding MapCenter, Mode=TwoWay}"                   ZoomLevel="{Binding ZoomLevel, Mode=TwoWay}">               <bing:MapItemsControl ItemsSource="{Binding Earthquakes}"                                   ItemTemplate="{StaticResource EarthquakeTemplate}" />               <bing:MapItemsControl ItemsSource="{Binding Volcanos}"                                   ItemTemplate="{StaticResource VolcanoTemplate}" />         </bing:Map>           <basic:TabControl x:Name="tabs" VerticalAlignment="Bottom" MaxHeight="25" Opacity="0.7">             <basic:TabItem Margin="90,0,-90,0" MouseLeftButtonUp="TabItem_MouseLeftButtonUp">                 <basic:TabItem.Header>                     <TextBlock x:Name="txtHeader" Text="Options"                                FontSize="13" FontWeight="Bold" />                 </basic:TabItem.Header>                   <StackPanel Orientation="Horizontal">                     <TextBlock Text="Earthquakes:" FontWeight="Bold" Margin="3" />                     <StackPanel Margin="3">                         <CheckBox Content=" &lt;

• ParallelWork: Feature rich multithreaded fluent task execution library for WPF

  - by oazabir

  ParallelWork is an open source free helper class that lets you run multiple work in parallel threads, get success, failure and progress update on the WPF UI thread, wait for work to complete, abort all work (in case of shutdown), queue work to run after certain time, chain parallel work one after another. It’s more convenient than using .NET’s BackgroundWorker because you don’t have to declare one component per work, nor do you need to declare event handlers to receive notification and carry additional data through private variables. You can safely pass objects produced from different thread to the success callback. Moreover, you can wait for work to complete before you do certain operation and you can abort all parallel work while they are in-flight. If you are building highly responsive WPF UI where you have to carry out multiple job in parallel yet want full control over those parallel jobs completion and cancellation, then the ParallelWork library is the right solution for you. I am using the ParallelWork library in my PlantUmlEditor project, which is a free open source UML editor built on WPF. You can see some realistic use of the ParallelWork library there. Moreover, the test project comes with 400 lines of Behavior Driven Development flavored tests, that confirms it really does what it says it does. The source code of the library is part of the “Utilities” project in PlantUmlEditor source code hosted at Google Code. The library comes in two flavors, one is the ParallelWork static class, which has a collection of static methods that you can call. Another is the Start class, which is a fluent wrapper over the ParallelWork class to make it more readable and aesthetically pleasing code. ParallelWork allows you to start work immediately on separate thread or you can queue a work to start after some duration. You can start an immediate work in a new thread using the following methods: void StartNow(Action doWork, Action onComplete) void StartNow(Action doWork, Action onComplete, Action<Exception> failed) For example, ParallelWork.StartNow(() => { workStartedAt = DateTime.Now; Thread.Sleep(howLongWorkTakes); }, () => { workEndedAt = DateTime.Now; }); Or you can use the fluent way Start.Work: Start.Work(() => { workStartedAt = DateTime.Now; Thread.Sleep(howLongWorkTakes); }) .OnComplete(() => { workCompletedAt = DateTime.Now; }) .Run(); Besides simple execution of work on a parallel thread, you can have the parallel thread produce some object and then pass it to the success callback by using these overloads: void StartNow<T>(Func<T> doWork, Action<T> onComplete) void StartNow<T>(Func<T> doWork, Action<T> onComplete, Action<Exception> fail) For example, ParallelWork.StartNow<Dictionary<string, string>>( () => { test = new Dictionary<string,string>(); test.Add("test", "test"); return test; }, (result) => { Assert.True(result.ContainsKey("test")); }); Or, the fluent way: Start<Dictionary<string, string>>.Work(() => { test = new Dictionary<string, string>(); test.Add("test", "test"); return test; }) .OnComplete((result) => { Assert.True(result.ContainsKey("test")); }) .Run(); You can also start a work to happen after some time using these methods: DispatcherTimer StartAfter(Action onComplete, TimeSpan duration) DispatcherTimer StartAfter(Action doWork,Action onComplete,TimeSpan duration) You can use this to perform some timed operation on the UI thread, as well as perform some operation in separate thread after some time. ParallelWork.StartAfter( () => { workStartedAt = DateTime.Now; Thread.Sleep(howLongWorkTakes); }, () => { workCompletedAt = DateTime.Now; }, waitDuration); Or, the fluent way: Start.Work(() => { workStartedAt = DateTime.Now; Thread.Sleep(howLongWorkTakes); }) .OnComplete(() => { workCompletedAt = DateTime.Now; }) .RunAfter(waitDuration);   There are several overloads of these functions to have a exception callback for handling exceptions or get progress update from background thread while work is in progress. For example, I use it in my PlantUmlEditor to perform background update of the application. // Check if there's a newer version of the app Start<bool>.Work(() => { return UpdateChecker.HasUpdate(Settings.Default.DownloadUrl); }) .OnComplete((hasUpdate) => { if (hasUpdate) { if (MessageBox.Show(Window.GetWindow(me), "There's a newer version available. Do you want to download and install?", "New version available", MessageBoxButton.YesNo, MessageBoxImage.Information) == MessageBoxResult.Yes) { ParallelWork.StartNow(() => { var tempPath = System.IO.Path.Combine( Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData), Settings.Default.SetupExeName); UpdateChecker.DownloadLatestUpdate(Settings.Default.DownloadUrl, tempPath); }, () => { }, (x) => { MessageBox.Show(Window.GetWindow(me), "Download failed. When you run next time, it will try downloading again.", "Download failed", MessageBoxButton.OK, MessageBoxImage.Warning); }); } } }) .OnException((x) => { MessageBox.Show(Window.GetWindow(me), x.Message, "Download failed", MessageBoxButton.OK, MessageBoxImage.Exclamation); }); The above code shows you how to get exception callbacks on the UI thread so that you can take necessary actions on the UI. Moreover, it shows how you can chain two parallel works to happen one after another. Sometimes you want to do some parallel work when user does some activity on the UI. For example, you might want to save file in an editor while user is typing every 10 second. In such case, you need to make sure you don’t start another parallel work every 10 seconds while a work is already queued. You need to make sure you start a new work only when there’s no other background work going on. Here’s how you can do it: private void ContentEditor_TextChanged(object sender, EventArgs e) { if (!ParallelWork.IsAnyWorkRunning()) { ParallelWork.StartAfter(SaveAndRefreshDiagram, TimeSpan.FromSeconds(10)); } } If you want to shutdown your application and want to make sure no parallel work is going on, then you can call the StopAll() method. ParallelWork.StopAll(); If you want to wait for parallel works to complete without a timeout, then you can call the WaitForAllWork(TimeSpan timeout). It will block the current thread until the all parallel work completes or the timeout period elapses. result = ParallelWork.WaitForAllWork(TimeSpan.FromSeconds(1)); The result is true, if all parallel work completed. If it’s false, then the timeout period elapsed and all parallel work did not complete. For details how this library is built and how it works, please read the following codeproject article: ParallelWork: Feature rich multithreaded fluent task execution library for WPF http://www.codeproject.com/KB/WPF/parallelwork.aspx If you like the article, please vote for me.

• JPA/Hibernate Embedded id and fields

  - by RoD

  I would like to do something like that: An object ReportingFile that can be a LogRequest or a LogReport file. ( both got the same structure) An object Reporting containing for one logRequest, a list of logReport with a date. An example (not working) would be: @Entity @AssociationOverride( name="logRequest.fileName", joinColumns = { @JoinColumn(name="log_request_file_name") } ) public class Reporting { @EmbeddedId private ReportingFile logRequest; @CollectionOfElements(fetch = FetchType.EAGER) @JoinTable(name = "t_reports", schema="", joinColumns = {@JoinColumn(name = "log_report")}) @Fetch(FetchMode.SELECT) private List<ReportingFile> reports; @Column(name="generated_date",nullable=true) private Date generatedDate; [...] } @Embeddable public class ReportingFile { @Column(name="file_name",length=255) private String fileName; @Column(name="xml_content") private Clob xmlContent;

• Loading FireMonkey style resourses with RTTI

  - by HeMet

  I am trying to write class that inherits from FMX TStyledControl. When style is updated it loads style resource objects to cache. I created project group for package with custom controls and test FMX HD project as it describes in Delphi help. After installing package and placing TsgSlideHost on the test form I run test app. It’s work well, but when I close it and try to rebuild package RAD Studio says “Error in rtl160.bpl” or “invalid pointer operation”. It seems what problem in LoadToCacheIfNeeded procedure from TsgStyledControl, but I’m not understand why. Is there any restriction on using RTTI with FMX styles or anything? TsgStyledControl sources: unit SlideGUI.TsgStyledControl; interface uses System.SysUtils, System.Classes, System.Types, FMX.Types, FMX.Layouts, FMX.Objects, FMX.Effects, System.UITypes, FMX.Ani, System.Rtti, System.TypInfo; type TCachedAttribute = class(TCustomAttribute) private fStyleName: string; public constructor Create(const aStyleName: string); property StyleName: string read fStyleName; end; TsgStyledControl = class(TStyledControl) private procedure CacheStyleObjects; procedure LoadToCacheIfNeeded(aField: TRttiField); protected function FindStyleResourceAs<T: class>(const AStyleLookup: string): T; function GetStyleName: string; virtual; abstract; function GetStyleObject: TControl; override; public procedure ApplyStyle; override; published { Published declarations } end; implementation { TsgStyledControl } procedure TsgStyledControl.ApplyStyle; begin inherited; CacheStyleObjects; end; procedure TsgStyledControl.CacheStyleObjects; var ctx: TRttiContext; typ: TRttiType; fld: TRttiField; begin ctx := TRttiContext.Create; try typ := ctx.GetType(Self.ClassType); for fld in typ.GetFields do LoadFromCacheIfNeeded(fld); finally ctx.Free end; end; function TsgStyledControl.FindStyleResourceAs<T>(const AStyleLookup: string): T; var fmxObj: TFmxObject; begin fmxObj := FindStyleResource(AStyleLookup); if Assigned(fmxObj) and (fmxObj is T) then Result := fmxObj as T else Result := nil; end; function TsgStyledControl.GetStyleObject: TControl; var S: TResourceStream; begin if (FStyleLookup = '') then begin if FindRCData(HInstance, GetStyleName) then begin S := TResourceStream.Create(HInstance, GetStyleName, RT_RCDATA); try Result := TControl(CreateObjectFromStream(nil, S)); Exit; finally S.Free; end; end; end; Result := inherited GetStyleObject; end; procedure TsgStyledControl.LoadToCacheIfNeeded(aField: TRttiField); var attr: TCustomAttribute; styleName: string; styleObj: TFmxObject; val: TValue; begin for attr in aField.GetAttributes do begin if attr is TCachedAttribute then begin styleName := TCachedAttribute(attr).StyleName; if styleName <> '' then begin styleObj := FindStyleResource(styleName); val := TValue.From<TFmxObject>(styleObj); aField.SetValue(Self, val); end; end; end; end; { TCachedAttribute } constructor TCachedAttribute.Create(const aStyleName: string); begin fStyleName := aStyleName; end; end.

• JAX-WS MarshalException with custom JAX-B bindings: Unable to marshal type "java.lang.String" as an

  - by MoneyMark

  I seem to be having an issue with Jax-WS and Jax-b playing nicely together. I need to consume a web-service, which has a predefined WSDL. When executing the generated client I am receiving the following error: javax.xml.ws.WebServiceException: javax.xml.bind.MarshalException - with linked exception: [com.sun.istack.SAXException2: unable to marshal type "java.lang.String" as an element because it is missing an @XmlRootElement annotation] This started occurring when I used an external custom binding file to map needlessly complex types to java.lang.string. Here is an excerpt from my binding file: <?xml version="1.0" encoding="UTF-8"?> <bindings xmlns="http://java.sun.com/xml/ns/jaxb" version="2.0" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"> <bindings schemaLocation="http://localhost:7777/GESOR/services/RegistryUpdatePort?wsdl#types?schema1" node="/xs:schema"> <bindings node="//xs:element[@name='StwrdCompany']//xs:complexType//xs:sequence//xs:element[@name='company_name']"> <property> <baseType name="java.lang.String" /> </property> </bindings> <bindings node="//xs:element[@name='StwrdCompany']//xs:complexType//xs:sequence//xs:element[@name='address1']"> <property> <baseType name="java.lang.String" /> </property> </bindings> <bindings node="//xs:element[@name='StwrdCompany']//xs:complexType//xs:sequence//xs:element[@name='address2']"> <property> <baseType name="java.lang.String" /> </property> </bindings> ...more fields </bindings> </bindings> When executing wsimport against the provided WSDL, StwrdCompany is generated with the following variables declared: @XmlRootElement(name = "StwrdCompany") public class StwrdCompany { @XmlElementRef(name = "company_name", type = JAXBElement.class) protected String companyName; @XmlElementRef(name = "address1", type = JAXBElement.class) protected String address1; @XmlElementRef(name = "address2", type = JAXBElement.class) ... more fields ... getters/setters @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "", propOrder = { "value" }) public static class CompanyName { @XmlValue protected String value; @XmlAttribute protected Boolean updateToNULL; /** * Gets the value of the value property. * * @return * possible object is * {@link String } * */ public String getValue() { return value; } /** * Sets the value of the value property. * * @param value * allowed object is * {@link String } * */ public void setValue(String value) { this.value = value; } /** * Gets the value of the updateToNULL property. * * @return * possible object is * {@link Boolean } * */ public boolean isUpdateToNULL() { if (updateToNULL == null) { return false; } else { return updateToNULL; } } /** * Sets the value of the updateToNULL property. * * @param value * allowed object is * {@link Boolean } * */ public void setUpdateToNULL(Boolean value) { this.updateToNULL = value; } ... more inner classes } } Finally, here is the associated snippet from the WSDL that seems to be causing such grief. <xs:element name="StwrdCompany"> <xs:complexType> <xs:sequence> <xs:element maxOccurs="1" minOccurs="0" name="company_name" nillable="true"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute default="false" name="updateToNULL" type="xs:boolean"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> <xs:element maxOccurs="1" minOccurs="0" name="address1" nillable="true"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute default="false" name="updateToNULL" type="xs:boolean"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> ... more fields in the same format <xs:element maxOccurs="1" minOccurs="0" name="p_source_timestamp" nillable="false" type="xs:string"/> </xs:sequence> <xs:attribute name="company_xid" type="xs:string"/> </xs:complexType> </xs:element> The reason for the custom binding is so I can map user input from a pojo into the StwrdCompany object more easily, whether it be direct instantiation or through the use of Dozer for bean mapping. I was unable to successfully map between the objects without the custom binding. Finally, one other thing I tried was setting a globalBinding definition: <globalBindings generateValueClass="false"></globalBindings> This caused the server to through an argument mismatch exception since the Soap Message was using xs:string xml types instead of passing the defined complex types, so I abandoned that idea. Any insight into what is causing the MarshalException or how to go about solving the issue of calling the webservice and mapping these objects more easily, is greatly appreciated. I've been searching for days and I sadly think I am stumped.

• The last MVVM you'll ever need?

  - by Nuri Halperin

  As my MVC projects mature and grow, the need to have some omnipresent, ambient model properties quickly emerge. The application no longer has only one dynamic pieced of data on the page: A sidebar with a shopping cart, some news flash on the side – pretty common stuff. The rub is that a controller is invoked in context of a single intended request. The rest of the data, even though it could be just as dynamic, is expected to appear on it's own. There are many solutions to this scenario. MVVM prescribes creating elaborate objects which expose your new data as a property on some uber-object with more properties exposing the "side show" ambient data. The reason I don't love this approach is because it forces fairly acute awareness of the view, and soon enough you have many MVVM objects laying around, and views have to start doing null-checks in order to ensure you really supplied all the values before binding to them. Ick. Just as unattractive is the ViewData dictionary. It's not strongly typed, and in both this and the MVVM approach someone has to populate these properties – n'est pas? Where does that live? With MVC2, we get the formerly-futures  feature Html.RenderAction(). The feature allows you plant a line in a view, of the format: <% Html.RenderAction("SessionInterest", "Session"); %> While this syntax looks very clean, I can't help being bothered by it. MVC was touting a very strong separation of concerns, the Model taking on the role of the business logic, the controller handling route and performing minimal view-choosing operations and the views strictly focused on rendering out angled-bracket tags. The RenderAction() syntax has the view calling some controller and invoking it inline with it's runtime rendering. This – to my taste – embeds too much  knowledge of controllers into the view's code – which was allegedly forbidden.  The one way flow "Controller Receive Data –> Controller invoke Model –> Controller select view –> Controller Hand data to view" now gets a "View calls controller and gets it's own data" which is not so one-way anymore. Ick. I toyed with some other solutions a bit, including some base controllers, special view classes etc. My current favorite though is making use of the ExpandoObject and dynamic features with C# 4.0. If you follow Phil Haack or read a bit from David Heyden you can see the general picture emerging. The game changer is that using the new dynamic syntax, one can sprout properties on an object and make use of them in the view. Well that beats having a bunch of uni-purpose MVVM's any day! Rather than statically exposed properties, we'll just use the capability of adding members at runtime. Armed with new ideas and syntax, I went to work: First, I created a factory method to enrich the focuse object: public static class ModelExtension { public static dynamic Decorate(this Controller controller, object mainValue) { dynamic result = new ExpandoObject(); result.Value = mainValue; result.SessionInterest = CodeCampBL.SessoinInterest(); result.TagUsage = CodeCampBL.TagUsage(); return result; } } This gives me a nice fluent way to have the controller add the rest of the ambient "side show" items (SessionInterest, TagUsage in this demo) and expose them all as the Model: public ActionResult Index() { var data = SyndicationBL.Refresh(TWEET_SOURCE_URL); dynamic result = this.Decorate(data); return View(result); } So now what remains is that my view knows to expect a dynamic object (rather than statically typed) so that the ASP.NET page compiler won't barf: <%@ Page Language="C#" Title="Ambient Demo" MasterPageFile="~/Views/Shared/Ambient.Master" Inherits="System.Web.Mvc.ViewPage<dynamic>" %> Notice the generic ViewPage<dynamic>. It doesn't work otherwise. In the page itself, Model.Value property contains the main data returned from the controller. The nice thing about this, is that the master page (Ambient.Master) also inherits from the generic ViewMasterPage<dynamic>. So rather than the page worrying about all this ambient stuff, the side bars and panels for ambient data all reside in a master page, and can be rendered using the RenderPartial() syntax: <% Html.RenderPartial("TagCloud", Model.SessionInterest as Dictionary<string, int>); %> Note here that a cast is necessary. This is because although dynamic is magic, it can't figure out what type this property is, and wants you to give it a type so its binder can figure out the right property to bind to at runtime. I use as, you can cast if you like. So there we go – no violation of MVC, no explosion of MVVM models and voila – right? Well, I could not let this go without a tweak or two more. The first thing to improve, is that some views may not need all the properties. In that case, it would be a waste of resources to populate every property. The solution to this is simple: rather than exposing properties, I change d the factory method to expose lambdas - Func<T> really. So only if and when a view accesses a member of the dynamic object does it load the data. public static class ModelExtension { // take two.. lazy loading! public static dynamic LazyDecorate(this Controller c, object mainValue) { dynamic result = new ExpandoObject(); result.Value = mainValue; result.SessionInterest = new Func<Dictionary<string, int>>(() => CodeCampBL.SessoinInterest()); result.TagUsage = new Func<Dictionary<string, int>>(() => CodeCampBL.TagUsage()); return result; } } Now that lazy loading is in place, there's really no reason not to hook up all and any possible ambient property. Go nuts! Add them all in – they won't get invoked unless used. This now requires changing the signature of usage on the ambient properties methods –adding some parenthesis to the master view: <% Html.RenderPartial("TagCloud", Model.SessionInterest() as Dictionary<string, int>); %> And, of course, the controller needs to call LazyDecorate() rather than the old Decorate(). The final touch is to introduce a convenience method to the my Controller class , so that the tedium of calling Decorate() everywhere goes away. This is done quite simply by adding a bunch of methods, matching View(object), View(string,object) signatures of the Controller class: public ActionResult Index() { var data = SyndicationBL.Refresh(TWEET_SOURCE_URL); return AmbientView(data); } //these methods can reside in a base controller for the solution: public ViewResult AmbientView(dynamic data) { dynamic result = ModelExtension.LazyDecorate(this, data); return View(result); } public ViewResult AmbientView(string viewName, dynamic data) { dynamic result = ModelExtension.LazyDecorate(this, data); return View(viewName, result); } The call to AmbientView now replaces any call the View() that requires the ambient data. DRY sattisfied, lazy loading and no need to replace core pieces of the MVC pipeline. I call this a good MVC day. Enjoy!

• Multiple Components in a JTree Node Renderer & Node Editor

  - by Samad Lotia

  I am attempting to create a JTree where a node has several components: a JPanel that holds a JCheckBox, followed by a JLabel, then a JComboBox. I have attached the code at the bottom if one wishes to run it. Fortunately the JTree correctly renders the components. However when I click on the JComboBox, the node disappears; if I click on the JCheckBox, it works fine. It seems that I am doing something wrong with how the TreeCellEditor is being set up. How could I resolve this issue? Am I going beyond the capabilities of JTree? Here's a quick overview of the code I have posted below. The class EntityListDialog merely creates the user interface. It is not useful to understand it other than the createTree method. Node is the data structure that holds information about each node in the JTree. All Nodes have a name, but samples may be null or an empty array. This should be evident by looking at EntityListDialog's createTree method. The name is used as the text of the JCheckBox. If samples is non-empty, it is used as the contents of the JCheckBox. NodeWithSamplesRenderer renders Nodes whose samples are non-empty. It creates the complicated user interface with the JPanel consisting of the JCheckBox and the JComboBox. NodeWithoutSamplesRenderer creates just a JCheckBox when samples is empty. RendererDispatcher decides whether to use a NodeWithSamplesRenderer or a NodeWithoutSamplesRenderer. This entirely depends on whether Node has a non-empty samples member or not. It essentially functions as a means for the NodeWith*SamplesRenderer to plug into the JTree. Code listing: import java.awt.*; import java.awt.event.*; import java.util.*; import javax.swing.*; import javax.swing.tree.*; public class EntityListDialog { final JDialog dialog; final JTree entitiesTree;

• Driving me INSANE: Unable to Retrieve Metadata for

  - by Loren

  I've been spending the past 3 days trying to fix this problem I'm encountering - it's driving me insane... I'm not quite sure what is causing this bug - here are the details: MVC4 + Entity Framework 4.4 + MySql + POCO/Code First I'm setting up the above configuration .. here are my classes: namespace BTD.DataContext { public class BTDContext : DbContext { public BTDContext() : base("name=BTDContext") { } protected override void OnModelCreating(DbModelBuilder modelBuilder) { base.OnModelCreating(modelBuilder); //modelBuilder.Conventions.Remove<System.Data.Entity.Infrastructure.IncludeMetadataConvention>(); } public DbSet<Product> Products { get; set; } public DbSet<ProductImage> ProductImages { get; set; } } } namespace BTD.Data { [Table("Product")] public class Product { [Key] public long ProductId { get; set; } [DisplayName("Manufacturer")] public int? ManufacturerId { get; set; } [Required] [StringLength(150)] public string Name { get; set; } [Required] [DataType(DataType.MultilineText)] public string Description { get; set; } [Required] [StringLength(120)] public string URL { get; set; } [Required] [StringLength(75)] [DisplayName("Meta Title")] public string MetaTitle { get; set; } [DataType(DataType.MultilineText)] [DisplayName("Meta Description")] public string MetaDescription { get; set; } [Required] [StringLength(25)] public string Status { get; set; } [DisplayName("Create Date/Time")] public DateTime CreateDateTime { get; set; } [DisplayName("Edit Date/Time")] public DateTime EditDateTime { get; set; } } [Table("ProductImage")] public class ProductImage { [Key] public long ProductImageId { get; set; } public long ProductId { get; set; } public long? ProductVariantId { get; set; } [Required] public byte[] Image { get; set; } public bool PrimaryImage { get; set; } public DateTime CreateDateTime { get; set; } public DateTime EditDateTime { get; set; } } } Here is my web.config setup... <connectionStrings> <add name="BTDContext" connectionString="Server=localhost;Port=3306;Database=btd;User Id=root;Password=mypassword;" providerName="MySql.Data.MySqlClient" /> </connectionStrings> The database AND tables already exist... I'm still pretty new with mvc but was using this tutorial The application builds fine.. however when I try to add a controller using Product (BTD.Data) as my model class and BTDContext (BTD.DataContext) as my data context class I receive the following error: Unable to retrieve metadata for BTD.Data.Product using the same DbCompiledModel to create context against different types of database servers is not supported. Instead, create a separate DbCompiledModel for each type of server being used. I am at a complete loss - I've scoured google with almost every different variation of that error message above I can think of but to no avail. Here are the things i can verify... MySql is working properly I'm using MySql Connector version 6.5.4 and have created other ASP.net web forms + entity framework applications with ZERO problems I have also tried including/removing this in my web.config: <system.data> <DbProviderFactories> <remove invariant="MySql.Data.MySqlClient"/> <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" /> </DbProviderFactories> I've literally been working on this bug for days - I'm to the point now that I would be willing to pay someone to solve it.. no joke... I'd really love to use MVC 4 and Razor - I was so excited to get started on this, but now i'm pretty discouraged - I truly appreciate any help/guidance on this! Also note - i'm using Entityframework from Nuget... Another Note I was using the default visual studio template that creates your MVC project with the account pages and other stuff. I JUST removed all references to the added files because they were trying to use the "DefaultConnection" which didn't exist - so i thought those files may be what was causing the error - however still no luck after removing them - I just wanted to let everyone know i'm using the visual studio MVC project template which pre-creates a bunch of files. I will be trying to recreate this all from a blank MVC project which doesn't have those files - i will update this once i test that Other References It appears someone else is having the same issues I am - the only difference is they are using sql server - I tried tweaking all my code to follow the suggestions on this stackoverflow question/answer here but still to no avail

• Reading All Users Session

  - by imran_ku07

    Introduction :            InProc Session is the widely used state management. Storing the session state Inproc is also the fastest method and is well-suited to small amounts of volatile data. Reading and writing current user Session is very easy. But some times we need to read all users session before taking a decision or sometimes we may need to check which users are currently active with the help of Session. But unfortunately there is no class in .Net Framework (i don't found myself) to read all user InProc Session Data. In this article i will use reflection to read all user Inproc Session.   Description :              This code will work equally in both MVC and webform, but for demonstration i will use a simple webform example. So let's create a simple Website and Add two aspx pages, Default.aspx and Default2.aspx. In Default.aspx just add a link to navigate to Default2.aspx and in Default.aspx.cs just add a Session. Default.aspx: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html ><head runat="server">    <title>Untitled Page</title></head><body>    <form id="form1" runat="server">    <div>        <a href="Default2.aspx">Click to navigate to next page</a>    </div>    </form></body></html>  Default.aspx.cs:  using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;public partial class Default : System.Web.UI.Page{    protected void Page_Load(object sender, EventArgs e)    {        Session["User"] = "User" + DateTime.Now;    }} Now when every user click this link will navigate to Default2.aspx where all the magic appears.Default2.aspx.cs: using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;using System.Reflection;using System.Web.SessionState;public partial class Default2 : System.Web.UI.Page{    protected void Page_Load(object sender, EventArgs e)    {        object obj = typeof(HttpRuntime).GetProperty("CacheInternal", BindingFlags.NonPublic | BindingFlags.Static).GetValue(null, null);        Hashtable c2 = (Hashtable)obj.GetType().GetField("_entries", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(obj);        foreach (DictionaryEntry entry in c2)        {            object o1 = entry.Value.GetType().GetProperty("Value", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(entry.Value, null);            if (o1.GetType().ToString() == "System.Web.SessionState.InProcSessionState")            {                SessionStateItemCollection sess = (SessionStateItemCollection)o1.GetType().GetField("_sessionItems", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(o1);                if (sess != null)                {                    if (sess["User"] != null)                    {                        Label1.Text += sess["User"] + " is Active.<br>";                    }                }            }        }    }}            Now just open more than one browsers or more than one browser instance and then navigate to Default.aspx and click the link, you will see all the user's Session data.    How this works :        InProc session data is stored in the HttpRuntime’s internal cache in an implementation of ISessionStateItemCollection that implements ICollection. In this code, first of all i got CacheInternal Static Property of HttpRuntime class and then with the help of this object i got _entries private member which is of type ICollection. Then simply enumerate this dictionary and only take object of type System.Web.SessionState.InProcSessionState and finaly got SessionStateItemCollection for each user.Summary :        In this article, I shows you how you can get all current user Sessions. However one thing you will find when executing this code is that it will not show the current user Session which is set in the current request context because Session will be saved after all the Page Events.

• Wrapping ASP.NET Client Callbacks

  - by Ricardo Peres

  Client Callbacks are probably the less known (and I dare say, less loved) of all the AJAX options in ASP.NET, which also include the UpdatePanel, Page Methods and Web Services. The reason for that, I believe, is it’s relative complexity: Get a reference to a JavaScript function; Dynamically register function that calls the above reference; Have a JavaScript handler call the registered function. However, it has some the nice advantage of being self-contained, that is, doesn’t need additional files, such as web services, JavaScript libraries, etc, or static methods declared on a page, or any kind of attributes. So, here’s what I want to do: Have a DOM element which exposes a method that is executed server side, passing it a string and returning a string; Have a server-side event that handles the client-side call; Have two client-side user-supplied callback functions for handling the success and error results. I’m going to develop a custom control without user interface that does the registration of the client JavaScript method as well as a server-side event that can be hooked by some handler on a page. My markup will look like this: 1: <script type="text/javascript"> 1:  2:  3: function onCallbackSuccess(result, context) 4: { 5: } 6:  7: function onCallbackError(error, context) 8: { 9: } 10:  </script> 2: <my:CallbackControl runat="server" ID="callback" SendAllData="true" OnCallback="OnCallback"/> The control itself looks like this: 1: public class CallbackControl : Control, ICallbackEventHandler 2: { 3: #region Public constructor 4: public CallbackControl() 5: { 6: this.SendAllData = false; 7: this.Async = true; 8: } 9: #endregion 10:  11: #region Public properties and events 12: public event EventHandler<CallbackEventArgs> Callback; 13:  14: [DefaultValue(true)] 15: public Boolean Async 16: { 17: get; 18: set; 19: } 20:  21: [DefaultValue(false)] 22: public Boolean SendAllData 23: { 24: get; 25: set; 26: } 27:  28: #endregion 29:  30: #region Protected override methods 31:  32: protected override void Render(HtmlTextWriter writer) 33: { 34: writer.AddAttribute(HtmlTextWriterAttribute.Id, this.ClientID); 35: writer.RenderBeginTag(HtmlTextWriterTag.Span); 36:  37: base.Render(writer); 38:  39: writer.RenderEndTag(); 40: } 41:  42: protected override void OnInit(EventArgs e) 43: { 44: String reference = this.Page.ClientScript.GetCallbackEventReference(this, "arg", "onCallbackSuccess", "context", "onCallbackError", this.Async); 45: String script = String.Concat("\ndocument.getElementById('", this.ClientID, "').callback = function(arg, context, onCallbackSuccess, onCallbackError){", ((this.SendAllData == true) ? "__theFormPostCollection.length = 0; __theFormPostData = ''; WebForm_InitCallback(); " : String.Empty), reference, ";};\n"); 46:  47: this.Page.ClientScript.RegisterStartupScript(this.GetType(), String.Concat("callback", this.ClientID), script, true); 48:  49: base.OnInit(e); 50: } 51:  52: #endregion 53:  54: #region Protected virtual methods 55: protected virtual void OnCallback(CallbackEventArgs args) 56: { 57: EventHandler<CallbackEventArgs> handler = this.Callback; 58:  59: if (handler != null) 60: { 61: handler(this, args); 62: } 63: } 64:  65: #endregion 66:  67: #region ICallbackEventHandler Members 68:  69: String ICallbackEventHandler.GetCallbackResult() 70: { 71: CallbackEventArgs args = new CallbackEventArgs(this.Context.Items["Data"] as String); 72:  73: this.OnCallback(args); 74:  75: return (args.Result); 76: } 77:  78: void ICallbackEventHandler.RaiseCallbackEvent(String eventArgument) 79: { 80: this.Context.Items["Data"] = eventArgument; 81: } 82:  83: #endregion 84: } And the event argument class: 1: [Serializable] 2: public class CallbackEventArgs : EventArgs 3: { 4: public CallbackEventArgs(String argument) 5: { 6: this.Argument = argument; 7: this.Result = String.Empty; 8: } 9:  10: public String Argument 11: { 12: get; 13: private set; 14: } 15:  16: public String Result 17: { 18: get; 19: set; 20: } 21: } You will notice two properties on the CallbackControl: Async: indicates if the call should be made asynchronously or synchronously (the default); SendAllData: indicates if the callback call will include the view and control state of all of the controls on the page, so that, on the server side, they will have their properties set when the Callback event is fired. The CallbackEventArgs class exposes two properties: Argument: the read-only argument passed to the client-side function; Result: the result to return to the client-side callback function, set from the Callback event handler. An example of an handler for the Callback event would be: 1: protected void OnCallback(Object sender, CallbackEventArgs e) 2: { 3: e.Result = String.Join(String.Empty, e.Argument.Reverse()); 4: } Finally, in order to fire the Callback event from the client, you only need this: 1: <input type="text" id="input"/> 2: <input type="button" value="Get Result" onclick="document.getElementById('callback').callback(callback(document.getElementById('input').value, 'context', onCallbackSuccess, onCallbackError))"/> The syntax of the callback function is: arg: some string argument; context: some context that will be passed to the callback functions (success or failure); callbackSuccessFunction: some function that will be called when the callback succeeds; callbackFailureFunction: some function that will be called if the callback fails for some reason. Give it a try and see if it helps!

• Shuffle tiles position in the beginning of the game XNA Csharp

  - by GalneGunnar

  Im trying to create a puzzlegame where you move tiles to certain positions to make a whole image. I need help with randomizing the tiles startposition so that they don't create the whole image at the beginning. There is also something wrong with my offset, that's why it's set to (0,0). I know my code is not good, but Im just starting to learn :] Thanks in advance My Game1 class: { public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; Texture2D PictureTexture; Texture2D FrameTexture; // Offset för bildgraff Vector2 Offset = new Vector2(0,0); //skapar en array som ska hålla delar av den stora bilden Square[,] squareArray = new Square[4, 4]; // Random randomeraBilder = new Random(); //Width och Height för bilden int pictureHeight = 95; int pictureWidth = 144; Random randomera = new Random(); int index = 0; MouseState oldMouseState; int WindowHeight; int WindowWidth; public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; //scalar Window till 800x 600y graphics.PreferredBackBufferWidth = 800; graphics.PreferredBackBufferHeight = 600; graphics.ApplyChanges(); } protected override void Initialize() { IsMouseVisible = true; base.Initialize(); } protected override void LoadContent() { spriteBatch = new SpriteBatch(GraphicsDevice); PictureTexture = Content.Load<Texture2D>(@"Images/bildgraff"); FrameTexture = Content.Load<Texture2D>(@"Images/framer"); //Laddar in varje liten bild av den stora bilden i en array for (int x = 0; x < 4; x++) { for (int y = 0; y < 4; y++) { Vector2 position = new Vector2(x * pictureWidth, y * pictureHeight); position = position + Offset; Rectangle square = new Rectangle(x * pictureWidth, y * pictureHeight, pictureWidth, pictureHeight); Square frame = new Square(position, PictureTexture, square, Offset, index); squareArray[x, y] = frame; index++; } } } protected override void UnloadContent() { } protected override void Update(GameTime gameTime) { if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); MouseState ms = Mouse.GetState(); if (oldMouseState.LeftButton == ButtonState.Pressed && ms.LeftButton == ButtonState.Released) { // ta reda på vilken position vi har tryckt på int col = ms.X / pictureWidth; int row = ms.Y / pictureHeight; for (int x = 0; x < squareArray.GetLength(0); x++) { for (int y = 0; y < squareArray.GetLength(1); y++) { // kollar om rutan är tom och så att indexet inte går utanför för "col" och "row" if (squareArray[x, y].index == 0 && col >= 0 && row >= 0 && col <= 3 && row <= 3) { if (squareArray[x, y].index == 0 * col) { //kollar om rutan brevid mouseclick är tom if (col > 0 && squareArray[col - 1, row].index == 0 || row > 0 && squareArray[col, row - 1].index == 0 || col < 3 && squareArray[col + 1, row].index == 0 || row < 3 && squareArray[col, row + 1].index == 0) { Square sqaure = squareArray[col, row]; Square hal = squareArray[x, y]; squareArray[x, y] = sqaure; squareArray[col, row] = hal; for (int i = 0; i < 4; i++) { for (int j = 0; j < 4; j++) { Vector2 goalPosition = new Vector2(x * pictureWidth, y * pictureHeight); squareArray[x, y].Swap(goalPosition); } } } } } } } } //if (oldMouseState.RightButton == ButtonState.Pressed && ms.RightButton == ButtonState.Released) //{ // for (int x = 0; x < 4; x++) // { // for (int y = 0; y < 4; y++) // { // } // } //} oldMouseState = ms; base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); WindowHeight = Window.ClientBounds.Height; WindowWidth = Window.ClientBounds.Width; Rectangle screenPosition = new Rectangle(0,0, WindowWidth, WindowHeight); spriteBatch.Begin(); spriteBatch.Draw(FrameTexture, screenPosition, Color.White); //Ritar ut alla brickorna förutom den som har index 0 for (int x = 0; x < 4; x++) { for (int y = 0; y < 4; y++) { if (squareArray[x, y].index != 0) { squareArray[x, y].Draw(spriteBatch); } } } spriteBatch.End(); base.Draw(gameTime); } } } My square class: class Square { public Vector2 position; public Texture2D grafTexture; public Rectangle square; public Vector2 offset; public int index; public Square(Vector2 position, Texture2D grafTexture, Rectangle square, Vector2 offset, int index) { this.position = position; this.grafTexture = grafTexture; this.square = square; this.offset = offset; this.index = index; } public void Draw(SpriteBatch spritebatch) { spritebatch.Draw(grafTexture, position, square, Color.White); } public void RandomPosition() { } public void Swap(Vector2 Goal ) { if (Goal.X > position.X) { position.X = position.X + 144; } else if (Goal.X < position.X) { position.X = position.X - 144; } else if (Goal.Y < position.Y) { position.Y = position.Y - 95; } else if (Goal.Y > position.Y) { position.Y = position.Y + 95; } } } }

• How to implement a 2d collision detection for Android

  - by Michael Seun Araromi

  I am making a 2d space shooter using opengl ES. Can someone please show me how to implement a collision detection between the enemy ship and player ship.

• readonly keyword

  - by nmarun

  This is something new that I learned about the readonly keyword. Have a look at the following class: 1: public class MyClass 2: { 3: public string Name { get; set; } 4: public int Age { get; set; } 5:  6: private readonly double Delta; 7:  8: public MyClass() 9: { 10: Initializer(); 11: } 12:  13: public MyClass(string name = "", int age = 0) 14: { 15: Name = name; 16: Age = age; 17: Initializer(); 18: } 19:  20: private void Initializer() 21: { 22: Delta = 0.2; 23: } 24: } I have a couple of public properties and a private readonly member. There are two constructors – one that doesn’t take any parameters and the other takes two parameters to initialize the public properties. I’m also calling the Initializer method in both constructors to initialize the readonly member. Now when I build this, the code breaks and the Error window says: “A readonly field cannot be assigned to (except in a constructor or a variable initializer)” Two things after I read this message: It’s such a negative statement. I’d prefer something like: “A readonly field can be assigned to (or initialized) only in a constructor or through a variable initializer” But in my defense, I AM assigning it in a constructor (only indirectly). All I’m doing is creating a method that does it and calling it in a constructor. Turns out, .net was not ‘frameworked’ this way. We need to have the member initialized directly in the constructor. If you have multiple constructors, you can just use the ‘this’ keyword on all except the default constructors to call the default constructor. This default constructor can then initialize your readonly members. This will ensure you’re not repeating the code in multiple places. A snippet of what I’m talking can be seen below: 1: public class Person 2: { 3: public int UniqueNumber { get; set; } 4: public string Name { get; set; } 5: public int Age { get; set; } 6: public DateTime DateOfBirth { get; set; } 7: public string InvoiceNumber { get; set; } 8:  9: private readonly string Alpha; 10: private readonly int Beta; 11: private readonly double Delta; 12: private readonly double Gamma; 13:  14: public Person() 15: { 16: Alpha = "FDSA"; 17: Beta = 2; 18: Delta = 3.0; 19: Gamma = 0.0989; 20: } 21:  22: public Person(int uniqueNumber) : this() 23: { 24: UniqueNumber = uniqueNumber; 25: } 26: } See the syntax in line 22 and you’ll know what I’m talking about. So the default constructor gets called before the one in line 22. These are known as constructor initializers and they allow one constructor to call another. The other ‘myth’ I had about readonly members is that you can set it’s value only once. This was busted as well (I recall Adam and Jamie’s show). Say you’ve initialized the readonly member through a variable initializer. You can over-write this value in any of the constructors any number of times. 1: public class Person 2: { 3: public int UniqueNumber { get; set; } 4: public string Name { get; set; } 5: public int Age { get; set; } 6: public DateTime DateOfBirth { get; set; } 7: public string InvoiceNumber { get; set; } 8:  9: private readonly string Alpha = "asdf"; 10: private readonly int Beta = 15; 11: private readonly double Delta = 0.077; 12: private readonly double Gamma = 1.0; 13:  14: public Person() 15: { 16: Alpha = "FDSA"; 17: Beta = 2; 18: Delta = 3.0; 19: Gamma = 0.0989; 20: } 21:  22: public Person(int uniqueNumber) : this() 23: { 24: UniqueNumber = uniqueNumber; 25: Beta = 3; 26: } 27:  28: public Person(string name, DateTime dob) : this() 29: { 30: Name = name; 31: DateOfBirth = dob; 32:  33: Alpha = ";LKJ"; 34: Gamma = 0.0898; 35: } 36:  37: public Person(int uniqueNumber, string name, int age, DateTime dob, string invoiceNumber) : this() 38: { 39: UniqueNumber = uniqueNumber; 40: Name = name; 41: Age = age; 42: DateOfBirth = dob; 43: InvoiceNumber = invoiceNumber; 44:  45: Alpha = "QWER"; 46: Beta = 5; 47: Delta = 1.0; 48: Gamma = 0.0; 49: } 50: } In the above example, every constructor over-writes the values for the readonly members. This is perfectly valid. There is a possibility that based on the way the object is instantiated, the readonly member will have a different value. Well, that’s all I have for today and read this as it’s on a related topic.

• How do I set up MVP for a Winforms solution?

  - by JonWillis

  Question moved from Stackoverflow - http://stackoverflow.com/questions/4971048/how-do-i-set-up-mvp-for-a-winforms-solution I have used MVP and MVC in the past, and I prefer MVP as it controls the flow of execution so much better in my opinion. I have created my infrastructure (datastore/repository classes) and use them without issue when hard coding sample data, so now I am moving onto the GUI and preparing my MVP. Section A I have seen MVP using the view as the entry point, that is in the views constructor method it creates the presenter, which in turn creates the model, wiring up events as needed. I have also seen the presenter as the entry point, where a view, model and presenter are created, this presenter is then given a view and model object in its constructor to wire up the events. As in 2, but the model is not passed to the presenter. Instead the model is a static class where methods are called and responses returned directly. Section B In terms of keeping the view and model in sync I have seen. Whenever a value in the view in changed, i.e. TextChanged event in .Net/C#. This fires a DataChangedEvent which is passed through into the model, to keep it in sync at all times. And where the model changes, i.e. a background event it listens to, then the view is updated via the same idea of raising a DataChangedEvent. When a user wants to commit changes a SaveEvent it fires, passing through into the model to make the save. In this case the model mimics the view's data and processes actions. Similar to #b1, however the view does not sync with the model all the time. Instead when the user wants to commit changes, SaveEvent is fired and the presenter grabs the latest details and passes them into the model. in this case the model does not know about the views data until it is required to act upon it, in which case it is passed all the needed details. Section C Displaying of business objects in the view, i.e. a object (MyClass) not primitive data (int, double) The view has property fields for all its data that it will display as domain/business objects. Such as view.Animals exposes a IEnumerable<IAnimal> property, even though the view processes these into Nodes in a TreeView. Then for the selected animal it would expose SelectedAnimal as IAnimal property. The view has no knowledge of domain objects, it exposes property for primitive/framework (.Net/Java) included objects types only. In this instance the presenter will pass an adapter object the domain object, the adapter will then translate a given business object into the controls visible on the view. In this instance the adapter must have access to the actual controls on the view, not just any view so becomes more tightly coupled. Section D Multiple views used to create a single control. i.e. You have a complex view with a simple model like saving objects of different types. You could have a menu system at the side with each click on an item the appropriate controls are shown. You create one huge view, that contains all of the individual controls which are exposed via the views interface. You have several views. You have one view for the menu and a blank panel. This view creates the other views required but does not display them (visible = false), this view also implements the interface for each view it contains (i.e. child views) so it can expose to one presenter. The blank panel is filled with other views (Controls.Add(myview)) and ((myview.visible = true). The events raised in these "child"-views are handled by the parent view which in turn pass the event to the presenter, and visa versa for supplying events back down to child elements. Each view, be it the main parent or smaller child views are each wired into there own presenter and model. You can literately just drop a view control into an existing form and it will have the functionality ready, just needs wiring into a presenter behind the scenes. Section E Should everything have an interface, now based on how the MVP is done in the above examples will affect this answer as they might not be cross-compatible. Everything has an interface, the View, Presenter and Model. Each of these then obviously has a concrete implementation. Even if you only have one concrete view, model and presenter. The View and Model have an interface. This allows the views and models to differ. The presenter creates/is given view and model objects and it just serves to pass messages between them. Only the View has an interface. The Model has static methods and is not created, thus no need for an interface. If you want a different model, the presenter calls a different set of static class methods. Being static the Model has no link to the presenter. Personal thoughts From all the different variations I have presented (most I have probably used in some form) of which I am sure there are more. I prefer A3 as keeping business logic reusable outside just MVP, B2 for less data duplication and less events being fired. C1 for not adding in another class, sure it puts a small amount of non unit testable logic into a view (how a domain object is visualised) but this could be code reviewed, or simply viewed in the application. If the logic was complex I would agree to an adapter class but not in all cases. For section D, i feel D1 creates a view that is too big atleast for a menu example. I have used D2 and D3 before. Problem with D2 is you end up having to write lots of code to route events to and from the presenter to the correct child view, and its not drag/drop compatible, each new control needs more wiring in to support the single presenter. D3 is my prefered choice but adds in yet more classes as presenters and models to deal with the view, even if the view happens to be very simple or has no need to be reused. i think a mixture of D2 and D3 is best based on circumstances. As to section E, I think everything having an interface could be overkill I already do it for domain/business objects and often see no advantage in the "design" by doing so, but it does help in mocking objects in tests. Personally I would see E2 as a classic solution, although have seen E3 used in 2 projects I have worked on previously. Question Am I implementing MVP correctly? Is there a right way of going about it? I've read Martin Fowler's work that has variations, and I remember when I first started doing MVC, I understood the concept, but could not originally work out where is the entry point, everything has its own function but what controls and creates the original set of MVC objects.

• How can I make a jQuery UI 'draggable()' div draggable for touchscreen?

  - by artlung

  I have a jQuery UI draggable() that works in Firefox and Chrome. The user interface concept is basically click to create a "post-it" type item. Basically, I click or tap on div#everything (100% high and wide) that listens for clicks, and an input textarea displays. You add text, and then when you're done it saves it. You can drag this element around. That is working on normal browsers, but on an iPad I can test with I can't drag the items around. If I touch to select (it then dims slightly), I can't then drag it. It won't drag left or right at all. I can drag up or down, but I'm not dragging the individual div, I'm dragging the whole webpage. So here's the code I use to capture clicks: $('#everything').bind('click', function(e){ var elem = document.createElement('DIV'); STATE.top = e.pageY; STATE.left = e.pageX; var e = $(elem).css({ top: STATE.top, left: STATE.left }).html('<textarea></textarea>') .addClass('instance') .bind('click', function(event){ return false; }); $(this).append(e); }); And here's the code I use to "save" the note and turn the input div into just a display div: $('textarea').live('mouseleave', function(){ var val = jQuery.trim($(this).val()); STATE.content = val; if (val == '') { $(this).parent().remove(); } else { var div = $(this).parent(); div.text(val).css({ height: '30px' }); STATE.height = 30; if ( div.width() !== div[0].clientWidth || div.height () !== div[0].clientHeight ) { while (div.width() !== div[0].clientWidth || div.height () !== div[0].clientHeight) { var h = div.height() + 10; STATE.height = h; div.css({ height: (h) + 'px' }); // element just got scrollbars } } STATE.guid = uniqueID() div.addClass('savedNote').attr('id', STATE.guid).draggable({ stop: function() { var offset = $(this).offset(); STATE.guid = $(this).attr('id'); STATE.top = offset.top; STATE.left = offset.left; STATE.content = $(this).text(); STATE.height = $(this).height(); STATE.save(); } }); STATE.save(); $(this).remove(); } }); And I have this code when I load the page for saved notes: $('.savedNote').draggable({ stop: function() { STATE.guid = $(this).attr('id'); var offset = $(this).offset(); STATE.top = offset.top; STATE.left = offset.left; STATE.content = $(this).text(); STATE.height = $(this).height(); STATE.save(); } }); My STATE object handles saving the notes. Onload, this is the whole html body: <body> <div id="everything"></div> <div class="instance savedNote" id="iddd1b0969-c634-8876-75a9-b274ff87186b" style="top:134px;left:715px;height:30px;">Whatever dude</div> <div class="instance savedNote" id="id8a129f06-7d0c-3cb3-9212-0f38a8445700" style="top:131px;left:347px;height:30px;">Appointment 11:45am</div> <div class="instance savedNote" id="ide92e3d13-afe8-79d7-bc03-818d4c7a471f" style="top:144px;left:65px;height:80px;">What do you think of a board where you can add writing as much as possible?</div> <div class="instance savedNote" id="idef7fe420-4c19-cfec-36b6-272f1e9b5df5" style="top:301px;left:534px;height:30px;">This was submitted</div> <div class="instance savedNote" id="id93b3b56f-5e23-1bd1-ddc1-9be41f1efb44" style="top:390px;left:217px;height:30px;">Hello world from iPad.</div> </body> So, my question is really: how can I make this work better on iPad? I'm not set on jQuery UI, I'm wondering if this is something I'm doing wrong with jQuery UI, or jQuery, or whether there may be better frameworks for doing cross-platform/backward compatible draggable() elements that will work for touchscreen UIs. More general comments about how to write UI components like this would be welcome as well. Thanks!

So, I have a class MapScreen which display my map: public class MapScreen extends MenuScreen Then, I have in the same file the MenuScreen class like this that allows to display the horizontal menu when I press the MENU key: abstract class MenuScreen extends MainScreen { boolean mMenuEnabled = false; CyclicHFManager mMenuManager = null; public MenuScreen() { mMenuManager = new CyclicHFManager(); mMenuManager.setBorder(BorderFactory.createBevelBorder(new XYEdges(4, 0, 0, 0), new XYEdges(Color.DARKBLUE, 0, 0, 0), new XYEdges( Color.WHITE, 0, 0, 0))); mMenuManager.setBackground(BackgroundFactory .createLinearGradientBackground(Color.DARKBLUE, Color.DARKBLUE, Color.LIGHTBLUE, Color.LIGHTBLUE)); for (int i = 0; i < 10; i++) { Bitmap nBitmap = new Bitmap(60, 60); Graphics g = new Graphics(nBitmap); g.setColor(Color.DARKBLUE); g.fillRect(0, 0, 60, 60); g.setColor(Color.WHITE); g.drawRect(0, 0, 60, 60); Font f = g.getFont().derive(Font.BOLD, 40); g.setFont(f); String text = String.valueOf(i); g.drawText(text, (60 - f.getAdvance(text)) >> 1, (60 - f .getHeight()) >> 1); Bitmap fBitmap = new Bitmap(60, 60); g = new Graphics(fBitmap); g.setColor(Color.DARKBLUE); g.fillRect(0, 0, 60, 60); g.setColor(Color.GOLD); g.drawRect(0, 0, 60, 60); g.setFont(f); g.drawText(text, (60 - f.getAdvance(text)) >> 1, (60 - f .getHeight()) >> 1); BitmapButtonField button = new BitmapButtonField(nBitmap, fBitmap); button.setCookie(String.valueOf(i)); button.setPadding(new XYEdges(0, 18, 0, 18)); button.setChangeListener(new FieldChangeListener() { public void fieldChanged(Field field, int context) { Dialog.inform("Button # " + (String) field.getCookie()); } }); mMenuManager.add(button); } } protected boolean keyDown(int keycode, int time) { if (Keypad.KEY_MENU == Keypad.key(keycode)) { if (mMenuManager.getManager() != null) { delete(mMenuManager); mMenuManager.mCyclicTurnedOn = false; } else { add(mMenuManager); mMenuManager.getField(2).setFocus(); mMenuManager.mCyclicTurnedOn = true; } return true; } else { return super.keyDown(keycode, time); } }} And finally my menu manager: public class CyclicHFManager extends HorizontalFieldManager { int mFocusedFieldIndex = 0; public boolean mCyclicTurnedOn = false; public void focusChangeNotify(int arg0) { super.focusChangeNotify(arg0); if (mCyclicTurnedOn) { int focusedFieldIndexNew = getFieldWithFocusIndex(); if (focusedFieldIndexNew != mFocusedFieldIndex) { if (focusedFieldIndexNew - mFocusedFieldIndex > 0) switchField(0, getFieldCount() - 1); else switchField(getFieldCount() - 1, 0); } } else { mFocusedFieldIndex = getFieldWithFocusIndex(); } } private void switchField(int prevIndex, int newIndex) { Field field = getField(prevIndex); delete(field); insert(field, newIndex); }} So as it is like this, it is working: when I press the MENU key, the menu appears, i can navigate between buttons, and it disappear when I press again the same key. The only problem is my menu isn't overlaying my map, it pushes the content up. I tried with the menu manager like in your first response, resizing the content manager but it is the same result. Max gave me the link http://stackoverflow.com/questions/1497073/blackberry-fields-layout-animation to do so, but I really don't know how to use it to make it work in my project... Thank you for your help! UPDATE This works great, it's what I wanted. However, I still have a problem because I'm under 4.5. So first in the MenuHostManager constructor, I deleted the USE_ALL_HEIGHT and change setPositionChild(mMenuManager, 0, Display.getHeight() - mMenuManager.getPreferredHeight()); like this to have the menu at the bottom of the screen. It worked. Then, instead of drawing my bitmaps, I did this: Bitmap nBitmap = EncodedImage.getEncodedImageResource("menu" + i + ".png").getBitmap(); BitmapButtonField button = new BitmapButtonField(nBitmap, nBitmap); And it worked too (no rollover for now, later). So it is great! I also overwrite the Paint method of my CyclicHFManager to have a background color, because I can't use the BorderFactory and BackgroundFactory... My menu bar has a color for now so it's ok. Then, because of these 2 classes missing, in my BitmapButtonField I had to delete the 2 setBorder functions that change the borders. And now i have my buttons pretty big like normal buttons with borders... How can I make the same effect as the setBorder functions under 4.5? (BTW, setBorder is not working under 4.5 too...). Thank you!

• Big smart ViewModels, dumb Views, and any model, the best MVVM approach?

  - by Edward Tanguay

  The following code is a refactoring of my previous MVVM approach (Fat Models, skinny ViewModels and dumb Views, the best MVVM approach?) in which I moved the logic and INotifyPropertyChanged implementation from the model back up into the ViewModel. This makes more sense, since as was pointed out, you often you have to use models that you either can't change or don't want to change and so your MVVM approach should be able to work with any model class as it happens to exist. This example still allows you to view the live data from your model in design mode in Visual Studio and Expression Blend which I think is significant since you could have a mock data store that the designer connects to which has e.g. the smallest and largest strings that the UI can possibly encounter so that he can adjust the design based on those extremes. Questions: I'm a bit surprised that I even have to "put a timer" in my ViewModel since it seems like that is a function of INotifyPropertyChanged, it seems redundant, but it was the only way I could get the XAML UI to constantly (once per second) reflect the state of my model. So it would be interesting to hear anyone who may have taken this approach if you encountered any disadvantages down the road, e.g. with threading or performance. The following code will work if you just copy the XAML and code behind into a new WPF project. XAML: <Window x:Class="TestMvvm73892.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:TestMvvm73892" Title="Window1" Height="300" Width="300"> <Window.Resources> <ObjectDataProvider x:Key="DataSourceCustomer" ObjectType="{x:Type local:CustomerViewModel}" MethodName="GetCustomerViewModel"/> </Window.Resources> <DockPanel DataContext="{StaticResource DataSourceCustomer}"> <StackPanel DockPanel.Dock="Top" Orientation="Horizontal"> <TextBlock Text="{Binding Path=FirstName}"/> <TextBlock Text=" "/> <TextBlock Text="{Binding Path=LastName}"/> </StackPanel> <StackPanel DockPanel.Dock="Top" Orientation="Horizontal"> <TextBlock Text="{Binding Path=TimeOfMostRecentActivity}"/> </StackPanel> </DockPanel> </Window> Code Behind: using System; using System.Windows; using System.ComponentModel; using System.Threading; namespace TestMvvm73892 { public partial class Window1 : Window { public Window1() { InitializeComponent(); } } //view model public class CustomerViewModel : INotifyPropertyChanged { private string _firstName; private string _lastName; private DateTime _timeOfMostRecentActivity; private Timer _timer; public string FirstName { get { return _firstName; } set { _firstName = value; this.RaisePropertyChanged("FirstName"); } } public string LastName { get { return _lastName; } set { _lastName = value; this.RaisePropertyChanged("LastName"); } } public DateTime TimeOfMostRecentActivity { get { return _timeOfMostRecentActivity; } set { _timeOfMostRecentActivity = value; this.RaisePropertyChanged("TimeOfMostRecentActivity"); } } public CustomerViewModel() { _timer = new Timer(CheckForChangesInModel, null, 0, 1000); } private void CheckForChangesInModel(object state) { Customer currentCustomer = CustomerViewModel.GetCurrentCustomer(); MapFieldsFromModeltoViewModel(currentCustomer, this); } public static CustomerViewModel GetCustomerViewModel() { CustomerViewModel customerViewModel = new CustomerViewModel(); Customer currentCustomer = CustomerViewModel.GetCurrentCustomer(); MapFieldsFromModeltoViewModel(currentCustomer, customerViewModel); return customerViewModel; } public static void MapFieldsFromModeltoViewModel(Customer model, CustomerViewModel viewModel) { viewModel.FirstName = model.FirstName; viewModel.LastName = model.LastName; viewModel.TimeOfMostRecentActivity = model.TimeOfMostRecentActivity; } public static Customer GetCurrentCustomer() { return Customer.GetCurrentCustomer(); } //INotifyPropertyChanged implementation public event PropertyChangedEventHandler PropertyChanged; private void RaisePropertyChanged(string property) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(property)); } } } //model public class Customer { public string FirstName { get; set; } public string LastName { get; set; } public DateTime TimeOfMostRecentActivity { get; set; } public static Customer GetCurrentCustomer() { return new Customer { FirstName = "Jim", LastName = "Smith", TimeOfMostRecentActivity = DateTime.Now }; } } }

• springTestContextBeforeTestMethod failed in Maven spring-test

  - by joejax

  I try to setup a project with spring-test using TestNg in Maven. The code is like: @ContextConfiguration(locations={"test-context.xml"}) public class AppTest extends AbstractTestNGSpringContextTests { @Test public void testApp() { assert true; } } A test-context.xml simply defined a bean: <bean id="app" class="org.sonatype.mavenbook.simple.App"/> I got error for Failed to load ApplicationContext when running mvn test from command line, seems it cannot find the test-context.xml file; however, I can get it run correctly inside Eclipse (with TestNg plugin). So, test-context.xml is under src/test/resources/, how do I indicate this in the pom.xml so that 'mvn test' command will work? Thanks, UPDATE: Thanks for the reply. Cannot load context file error was caused by I moved the file arround in different location since I though the classpath was the problem. Now I found the context file seems loaded from the Maven output, but the test is failed: Running TestSuite May 25, 2010 9:55:13 AM org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions INFO: Loading XML bean definitions from class path resource [test-context.xml] May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext prepareRefresh INFO: Refreshing org.springframework.context.support.GenericApplicationContext@171bbc9: display name [org.springframework.context.support.GenericApplicationContext@171bbc9]; startup date [Tue May 25 09:55:13 PDT 2010]; root of context hierarchy May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext obtainFreshBeanFactory INFO: Bean factory for application context [org.springframework.context.support.GenericApplicationContext@171bbc9]: org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99 May 25, 2010 9:55:13 AM org.springframework.beans.factory.support.DefaultListableBeanFactory preInstantiateSingletons INFO: Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99: defining beans [app,org.springframework.context.annotation.internalCommonAnnotationProcessor,org.springframework.context.annotation.internalAutowiredAnnotationProcessor,org.springframework.context.annotation.internalRequiredAnnotationProcessor]; root of factory hierarchy Tests run: 3, Failures: 2, Errors: 0, Skipped: 1, Time elapsed: 0.63 sec <<< FAILURE!

UPDATE: I think I got the problem (still don't know why) - Whenever I extends AbstractTestNGSpringContextTests or AbstractTransactionalTestNGSpringContextTests, the test will failed with this error: Failed tests: springTestContextBeforeTestMethod(org.sonatype.mavenbook.simple.AppTest) springTestContextAfterTestMethod(org.sonatype.mavenbook.simple.AppTest) So, eventually the error went away when I override the two methods. I don't think this is the right way, didn't find much info from spring-test doc. If you know spring test framework, please shred some light on this.
