• Making a non-trivial Image and Video Gallery with a really nice interface

  - by Cawas

  Short part: I'm starting to build an Image and Video Gallery for our intranet. It's pretty much like an image gallery with video thumbnails that play on click. It's just good to keep that in mind because caching and streaming happen in very different ways there. It will serve to browse our reference database, which will also contain searching, tagging and voting. There are 3 features that I need to begin with: Quick preview of thumbnails from each Gallery Fast zoom in / out Animated scrolling Now to the long part, since I can't seem to reduce this: I hope this question belongs here. Maybe people can read this through and identify with it, specially since I expect answers to be pretty specific. The first plan was getting Apple's mobile me gallery as base, because it just so happens to have all those 3 features. If you've never seem it, you should check it out. Move the mouse over each collection and you'll get a nice preview "per pixel". Carousel got a really good scrolling, not just because of the pretty effect. I like it much more than cooliris, but it would be nice to have it in several rows, maybe without the magnifying effect... Then it could be all in the same place with the zoom. The more the features blend-in together, the better. Zooming out with the mouse, scrolling by dragging, once the zoom is really out it becomes a browsing through galleries, with the quick-show preview of each, all properly cached and fast. That'd be perfect. A very compelling interface will be important in this project. Well, my point here is just describing what I need and hope to hear from people with more experience in all that stuff of what's already done and what I'd have to do myself. And how (i.e. which framework to use) to do it. To begin with, I've found a gallery demo and its source code (I think it was from here, but the link seems broken now). I guess it was made in SproutCore, which is what mobileme was based upon. Definitely with JQuery (which already seems a little slow). But I'm still missing two features there: the carousel and the fast zoom (it's just not as slow as the zoom in this demo with cappuccino). Then I've found a supposedly better one with a pretty good and similar zoom, that I'm not sure if it's using any framework and is already in php. Right now it'd be better having just the HTML, no server-side, since I'm building interface first. So, can anyone point directions? There are way too many options! Should I look for another solution closer to what I need, or try and tweak this one? I'm not familiar with any framework at all. Sorry for bringing this question that I will have to answer myself anyway sooner or later and sorry that I couldn't make this smaller. Thanks.

• Many to many self join through junction table

  - by Peter

  I have an EF model that can self-reference through an intermediary class to define a parent/child relationship. I know how to do a pure many-to-many relationship using the Map command, but for some reason going through this intermediary class is causing problems with my mappings. The intermediary class provides additional properties for the relationship. See the classes, modelBinder logic and error below: public class Equipment { [Key] public int EquipmentId { get; set; } public virtual List<ChildRecord> Parents { get; set; } public virtual List<ChildRecord> Children { get; set; } } public class ChildRecord { [Key] public int ChildId { get; set; } [Required] public int Quantity { get; set; } [Required] public Equipment Parent { get; set; } [Required] public Equipment Child { get; set; } } I've tried building the mappings in both directions, though I only keep one set in at a time: modelBuilder.Entity<ChildRecord>() .HasRequired(x => x.Parent) .WithMany(x => x.Children ) .WillCascadeOnDelete(false); modelBuilder.Entity<ChildRecord>() .HasRequired(x => x.Child) .WithMany(x => x.Parents) .WillCascadeOnDelete(false); OR modelBuilder.Entity<Equipment>() .HasMany(x => x.Parents) .WithRequired(x => x.Child) .WillCascadeOnDelete(false); modelBuilder.Entity<Equipment>() .HasMany(x => x.Children) .WithRequired(x => x.Parent) .WillCascadeOnDelete(false); Regardless of which set I use, I get the error: The foreign key component 'Child' is not a declared property on type 'ChildRecord'. Verify that it has not been explicitly excluded from the model and that it is a valid primitive property. when I try do deploy my ef model to the database. If I build it without the modelBinder logic in place then I get two ID columns for Child and two ID columns for Parent in my ChildRecord table. This makes sense since it tries to auto create the navigation properties from Equipment and doesn't know that there are already properties in ChildRecord to fulfill this need. I tried using Data Annotations on the class, and no modelBuilder code, this failed with the same error as above: [Required] [ForeignKey("EquipmentId")] public Equipment Parent { get; set; } [Required] [ForeignKey("EquipmentId")] public Equipment Child { get; set; } AND [InverseProperty("Child")] public virtual List<ChildRecord> Parents { get; set; } [InverseProperty("Parent")] public virtual List<ChildRecord> Children { get; set; } I've looked at various other answers around the internet/SO, and the common difference seems to be that I am self joining where as all the answers I can find are for two different types.

• Spring Framework 3 and session attributes

  - by newbie

  I have form object that I set to request in GET request handler in my Spring controller. First time user enters to page, a new form object should be made and set to request. If user sends form, then form object is populated from request and now form object has all user givern attributes. Then form is validated and if validation is ok, then form is saved to database. If form is not validated, I want to save form object to session and then redirect to GET request handling page. When request is redirected to GET handler, then it should check if session contains form object. I have figured out that there is @SessionAttributes("form") annotation in Spring, but for some reason following doesnt work, because at first time, session attribute form is null and it gives error: org.springframework.web.HttpSessionRequiredException: Session attribute 'form' required - not found in session Here is my controller: @RequestMapping(value="form", method=RequestMethod.GET) public ModelAndView viewForm(@ModelAttribute("form") Form form) { ModelAndView mav = new ModelAndView("form"); if(form == null) form = new Form(); mav.addObject("form", form); return mav; } @RequestMapping(value="form", method=RequestMethod.POST) @Transactional(readOnly = true) public ModelAndView saveForm(@ModelAttribute("form") Form form) { FormUtils.populate(form, request); if(form.validate()) { formDao.save(); } else { return viewForm(form); } return null; }

• SQL Subquery in LINQ for Entity Framework 4.0

  - by Jorin

  I'm new to LINQ and EF, but I've been able to stumble through for the majority of the queries I have, but this one has me completely confused. No matter what I try, it comes up in SQL Profiler as a big mess :-). I have two tables: Users and UsersProjects. The goal of this query is to list all the users who are working on projects with the specified user. Here is the query as I have it written in SQL. It's a subquery, but I don't know of a way to simplify it further, but I'm open to suggestions there as well. SELECT DISTINCT Users.FirstName, Users.LastName FROM Users INNER JOIN UsersProjects ON Users.ID=UsersProjects.UserID WHERE UsersProjects.ProjectID IN (SELECT ProjectID FROM UsersProjects WHERE UserID=@UserID) Anybody able to help?? It seems like a fairly simple subquery in SQL, but in LINQ, I'm baffled. Thanks, Jorin

  Hi Guys, I was having issues in log4net when i updated my solutions to .net 4.0 , and then i downloaded the source of it and built log4net and targeted it to .net 4.0 and used it in my projects. initially when i referred log4net that is targeted to run time 2.0 it complied and run the application but log did not work. now when i run my project with log4net targeted to .net 4.0 i get the error " The type initializer for 'Log4NetTest.TestLog' threw an exception."

• Play Framework: Error getting sequence nextval using H2 in-memory database

• Strange Play Framework 2.2 exceptions after trying to add MySQL / slick

  - by Mike Cialowicz

  I'm working on a Play 2.2 application, and things have gone a bit south on me since I've tried adding my DB layer. Below are my build.sbt dependencies. As you can see I use mysql-connector-java and play-slick: libraryDependencies ++= Seq( jdbc, anorm, cache, "joda-time" % "joda-time" % "2.3", "mysql" % "mysql-connector-java" % "5.1.26", "com.typesafe.play" %% "play-slick" % "0.5.0.8", "com.aetrion.flickr" % "flickrapi" % "1.1" ) My application.conf has some similarly simple DB stuff in it: db.default.url="jdbc:mysql://localhost/myDb" db.default.driver="com.mysql.jdbc.Driver" db.default.user="root" db.default.pass="" This is what it looks like when my Play server starts: [info] play - Listening for HTTP on /0:0:0:0:0:0:0:0:9000 (Server started, use Ctrl+D to stop and go back to the console...) [info] Compiling 1 Scala source to C:\bbq\cats\in\space [info] play - database [default] connected at jdbc:mysql://localhost/myDb [info] play - Application started (Dev) So, it appears that Play can connect to the MySQL DB just fine (I think). However, I get this exception when I make any request to my server: [error] p.nettyException - Exception caught in Netty java.lang.NoSuchMethodError: akka.actor.ActorSystem.dispatcher()Lscala/concurren t/ExecutionContext; at play.core.Invoker$.<init>(Invoker.scala:24) ~[play_2.10.jar:2.2.0] at play.core.Invoker$.<clinit>(Invoker.scala) ~[play_2.10.jar:2.2.0] at play.api.libs.concurrent.Execution$Implicits$.defaultContext$lzycompu te(Execution.scala:7) ~[play_2.10.jar:2.2.0] at play.api.libs.concurrent.Execution$Implicits$.defaultContext(Executio n.scala:6) ~[play_2.10.jar:2.2.0] at play.api.libs.concurrent.Execution$.<init>(Execution.scala:10) ~[play _2.10.jar:2.2.0] at play.api.libs.concurrent.Execution$.<clinit>(Execution.scala) ~[play_ 2.10.jar:2.2.0] The odd thing is that the 2nd request (to the exact same URL, same controller, no changes) comes back with a different error: [error] p.nettyException - Exception caught in Netty java.lang.NoClassDefFoundError: Could not initialize class play.api.libs.concurr ent.Execution$ at play.core.server.netty.PlayDefaultUpstreamHandler.handleAction$1(Play DefaultUpstreamHandler.scala:194) ~[play_2.10.jar:2.2.0] at play.core.server.netty.PlayDefaultUpstreamHandler.messageReceived(Pla yDefaultUpstreamHandler.scala:169) ~[play_2.10.jar:2.2.0] at com.typesafe.netty.http.pipelining.HttpPipeliningHandler.messageRecei ved(HttpPipeliningHandler.java:62) ~[netty-http-pipelining.jar:na] at org.jboss.netty.handler.codec.http.HttpContentDecoder.messageReceived (HttpContentDecoder.java:108) ~[netty-3.6.5.Final.jar:na] at org.jboss.netty.channel.Channels.fireMessageReceived(Channels.java:29 6) ~[netty-3.6.5.Final.jar:na] at org.jboss.netty.handler.codec.frame.FrameDecoder.unfoldAndFireMessage Received(FrameDecoder.java:459) ~[netty-3.6.5.Final.jar:na] The URL / controller that I'm requesting just renders a static web page and doesn't do anything of any significance. It was working just fine before I started adding my DB layer. I'm rather stuck. Any help would be greatly appreciated, thanks. I'm using Scala 2.10.2, Play 2.2.0, and MySQL Server 5.6.14.0 (community edition).

• Best current framework for unit testing EJB3 / JPA

  - by kennygrimm

  Starting new project using EJB 3 / JPA, mainly stateless session beans and batch jobs. I've used JUnit in the past on standard Java webapps and it seemed to work pretty well. In EJB2 unit testing was a pain and required a running container such as JBoss to make the calls into. Now that we're going to be working in EJB3 / JPA I'd like to know what companies are using to write and run these tests. Are Junit and JMock still considered relevant or are there other newer frameworks that have come around that we should investigate?

• "Admin module" taking over [Yii framework]

  - by Flavius

  Hi I have an "admin" module and I want it to serve "dynamic controllers", i.e. to provide a default behaviour for controllers which don't really exist ("virtual controllers"). I've invented a lightweight messaging mechanism for loose communication between modules. I'd like to use it such that when e.g. ?r=admin/users/index is requested, it will call the "virtual controller" "UserController" of AdminModule, which would, by default, use this messaging mechanism to notify the real module "UsersModule" it can answer to the request. I thought about simulating this behaviour in AdminModule::init(), but at that point I have no way of deciding whether the action can be processed by a real controller or not, or at least I don't know how to do it. This is because of the way Yii works: bottom-up, the controller is the one that renders the view AND the application layout (or the module's, if it exists), for example. I don't think the module even has a word to say about handling a given controller+action or not. To recap, I'm looking for a kind of CWebModule::missingController($controllerId,$actionId), just like CController::missingAction($actionId), or a workaround to simulate that. That would possibly be in CWebModule::init() or somewhere where I can find out whether the controller actually exists, in which case it's his job to handle it the $actionID and $controllerID whether the module $controllerID exists (I didn't type it wrong, in r=admin/users/index, "users" is the actual module, as specified in the application's config).

• ASP.Net Entity Framework, objectcontext error

  - by Chris Klepeis

  I'm building a 4 layered ASP.Net web application. The layers are: Data Layer Entity Layer Business Layer UI Layer The entity layer has my data model classes and is built from my entity data model (edmx file) in the datalayer using T4 templates (POCO). The entity layer is referenced in all other layers. My data layer has a class called SourceKeyRepository which has a function like so: public IEnumerable<SourceKey> Get(SourceKey sk) { using (dmc = new DataModelContainer()) { var query = from SourceKey in dmc.SourceKeys select SourceKey; if (sk.sourceKey1 != null) { query = from SourceKey in query where SourceKey.sourceKey1 == sk.sourceKey1 select SourceKey; } return query; } } Lazy loading is disabled since I do not want my queries to run in other layers of this application. I'm receiving the following error when attempting to access the information in the UI layer: The ObjectContext instance has been disposed and can no longer be used for operations that require a connection. I'm sure this is because my DataModelContainer "dmc" was disposed. How can I return this IEnumerable object from my data layer so that it does not rely on the ObjectContext, but solely on the DataModel? Is there a way to limit lazy loading to only occur in the data layer?

• WPF slow to start on x64 in .NET Framework 4.0

  - by Robert Fraser

  I've noticed that if I build my WPF application for Any CPU/x64, it takes MUCH longer to start (on the order of about 20 seconds) or to load new controls than it does if started on x86 (in release & debug modes, inside or outside of VS). This occurs with even the simplest WPF apps. The problem is discussed in this MSDN thread, but no answer was provided there. This happens only with .NET 4.0 -- in 3.5 SP1, x64 was just as fast as x86. Interestingly, Microsoft seems to know about this problem since the default for a new WPF project in VS2010 is x86. Is this a real bug or am I just doing it wrong? EDIT: Possibly related to this: http://stackoverflow.com/questions/2788215/slow-databinding-setup-time-in-c-net-4-0. I'm using data binding heavily.

• Contructor parameters for dependent classes with Unity Framework

  - by Onisemus

  I just started using the Unity Application Block to try to decouple my classes and make it easier for unit testing. I ran into a problem though that I'm not sure how to get around. Looked through the documentation and did some Googling but I'm coming up dry. Here's the situation: I have a facade-type class which is a chat bot. It is a singleton class which handles all sort of secondary classes and provides a central place to launch and configure the bot. I also have a class called AccessManager which, well, manages access to bot commands and resources. Boiled down to the essence, I have the classes set up like so. public class Bot { public string Owner { get; private set; } public string WorkingDirectory { get; private set; } private IAccessManager AccessManager; private Bot() { // do some setup // LoadConfig sets the Owner & WorkingDirectory variables LoadConfig(); // init the access mmanager AccessManager = new MyAccessManager(this); } public static Bot Instance() { // singleton code } ... } And the AccessManager class: public class MyAccessManager : IAccessManager { private Bot botReference; public MyAccesManager(Bot botReference) { this.botReference = botReference; SetOwnerAccess(botReference.Owner); } private void LoadConfig() { string configPath = Path.Combine( botReference.WorkingDirectory, "access.config"); // do stuff to read from config file } ... } I would like to change this design to use the Unity Application Block. I'd like to use Unity to generate the Bot singleton and to load the AccessManager interface in some sort of bootstrapping method that runs before anything else does. public static void BootStrapSystem() { IUnityContainer container = new UnityContainer(); // create new bot instance Bot newBot = Bot.Instance(); // register bot instance container.RegisterInstance<Bot>(newBot); // register access manager container.RegisterType<IAccessManager,MyAccessManager>(newBot); } And when I want to get a reference to the Access Manager inside the Bot constructor I can just do: IAcessManager accessManager = container.Resolve<IAccessManager>(); And elsewhere in the system to get a reference to the Bot singleton: // do this Bot botInstance = container.Resolve<Bot>(); // instead of this Bot botInstance = Bot.Instance(); The problem is the method BootStrapSystem() is going to blow up. When I create a bot instance it's going to try to resolve IAccessManager but won't be able to because I haven't registered the types yet (that's the next line). But I can't move the registration in front of the Bot creation because as part of the registration I need to pass the Bot as a parameter! Circular dependencies!! Gah!!! This indicates to me I have a flaw in the way I have this structured. But how do I fix it? Help!!

• Unity framework DependencyAttribute only works for public properties?

  - by rally25rs

  I was trying to clean up some accessability stuff in my code, and inadvertently broke Unity dependency injection. After a while I realized that I marked some public properties that I didn't really want exposed outside my DLLs to internal. Then I started getting exceptions. So it seems that using the [Dependency] attribute in Unity only works for public properties. I suppose that makes sense since the internal and private props wouldnt be visible to the Unity assembly, but feels really dirty to have a bunch of public properties that you never want anyone to set or be able to set, other than Unity. Is there a way to let unity set internal or private properties too? Here is the unit test I'd like to see pass. Currently only the public prop test passes: [TestFixture] public class UnityFixture { [Test] public void UnityCanSetPublicDependency() { UnityContainer container = new UnityContainer(); container.RegisterType<HasPublicDep, HasPublicDep>(); container.RegisterType<TheDep, TheDep>(); var i = container.Resolve<HasPublicDep>(); Assert.IsNotNull(i); Assert.IsNotNull(i.dep); } [Test] public void UnityCanSetInternalDependency() { UnityContainer container = new UnityContainer(); container.RegisterType<HasInternalDep, HasInternalDep>(); container.RegisterType<TheDep, TheDep>(); var i = container.Resolve<HasInternalDep>(); Assert.IsNotNull(i); Assert.IsNotNull(i.dep); } [Test] public void UnityCanSetPrivateDependency() { UnityContainer container = new UnityContainer(); container.RegisterType<HasPrivateDep, HasPrivateDep>(); container.RegisterType<TheDep, TheDep>(); var i = container.Resolve<HasPrivateDep>(); Assert.IsNotNull(i); Assert.IsNotNull(i.depExposed); } } public class HasPublicDep { [Dependency] public TheDep dep { get; set; } } public class HasInternalDep { [Dependency] internal TheDep dep { get; set; } } public class HasPrivateDep { [Dependency] private TheDep dep { get; set; } public TheDep depExposed { get { return this.dep; } } } public class TheDep { } Updated: I noticed the call stack to set the property passed from: UnityCanSetPublicDependency() --> Microsoft.Practices.Unity.dll --> Microsoft.Practices.ObjectBuilder2.dll --> HasPublicDep.TheDep.set() So in an attempt to at least make the internal version work, I added these to my assembly's properties: [assembly: InternalsVisibleTo("Microsoft.Practices.Unity")] [assembly: InternalsVisibleTo("Microsoft.Practices.Unity.Configuration")] [assembly: InternalsVisibleTo("Microsoft.Practices.ObjectBuilder2")] However, no change. Unity/ObjectBuilder still won't set the internal property

The way I do this is by setting the 10.6 SDK as the base SDK, weak-linking all frameworks and setting the deployment target to 10.5 as described in: http://developer.apple.com/mac/library/DOCUMENTATION/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html This works fine; before making a call that is Snow Leopard-only I need to check that the selector or indeed the class actually exist. Or I can just check the OS version before making the call. The problem is that this is incredibly fragile. If I make a single call that is 10.6 only I blow Leopard-compatibility. So using even the normal code code completion feature can be dangerous. My question: is there any way of checking which calls are not defined on 10.5 before doing a release build? Some kind of static analysis, or even just a trick (a target set the other SDK?) would do. I obviously should test on a Leopard machine before releasing anything, but even so I can't possibly go through all paths of the program before every release. Any advice would be appreciated. Best regards, Frank

• Synchronizing two SQL Server databases using MS Sync Framework

  - by Immortal

  I have one central SQL Server database which can be offline from time to time. I have a desktop application using Local DB Cache (SQL CE) to synchronize with the central database and I also have a web application with its own SQL Server that I'd also would like to keep synchronized. All synchronizations must be bidirectional. Is there a way to synchronize my central database with web application's database in the same way as I synchronize my central database with desktop client? I know about collaboration scenarios and peer-to-peer synchronization but I would like to avoid manual provisioning of databases. I'd like to use integrated sql server 2008 change tracking just like in the SQL CE <-- SQL Server scenario.

• Sync Framework, Local Database Cache, and my DAL

  - by Refracted Paladin

  I am creating a WPF app that needs to allow users to work in a temporary disconnected state and I plan to use a Local Database Cache. My question's are about my data access layer. Do you typically create the whole DAL to point at the Cache or both and create a switching mechanism? Is Entity's a good way to go for my DAL against the Cache? I am used to L2S but my understanding is that I can't use that against SQLCE, correct? Thanks! PS: Any good resources out there for using Sync, Linq, and WPF? Tutorials, videos, etc?

• TPL v/s Reactive Framework

  - by Abhijeet Patel

  When would one choose to use Rx over TPL or are the 2 frameworks orthogonal? From what I understand Rx is primarily intended to provide an abstraction over events and allow composition but it also allows for providing an abstraction over async operations. using the Createxx overloads and the Fromxxx overloads and cancellation via disposing the IDisposable returned. TPL also provides an abstraction for operations via Task and cancellation abilities. My dilemma is when to use which and for what scenarios?

• Simple Inversion of Control framework for Java/Scala

  - by Alexey Romanov

  I am looking for a simple to use IoC container for GUI applications written in Java/Scala. It should support Convention over Configuration, lifecycle management, configuration in code (preferably without any XML needed at all), and checking dependencies at compile-time as much as possible. Something similar to Autofac would be perfect.

• Binding DataGridComboBoxColumn to a one to many entity framework relation

  - by Cristian

  I have two tables in the model, one table contains entries related to the other table in a one to many relations, for example: Table User ID Name Table Comments ID UserID Title Text I want to show a datagrid in a WPF window with two columns, one text column with the User name and another column with a combobox showing all the comments made by the user. The datagrid definition is like this: <DataGrid AutoGenerateColumns="False" [layout options...] Name="dataGrid1" ItemsSource="{Binding}"> <DataGrid.Columns> <DataGridTextColumn Header="Name" Binding="{Binding Path=Name}"/> <DataGridComboBoxColumn Header="Comments" SelectedValueBinding="{Binding Path=UserID}" SelectedValuePath="ID" DisplayMemberPath="Title" ItemsSource="{Binding Path=Comments}" /> </DataGrid.Columns> </DataGrid> in the code I assign the DataContext like this: dataGrid1.DataContext = entities.Users; The entity User has a property named Comments that leads to all the comments made by the user. The queries are returning data and the user names are shown but the combobox is not being filled. May be the approach is totally wrong or I'm just missing a very simple point here, I'm opened to learn better methods to do this. Thanks

• When using a mocking framework and MSPEC where do you set your stubs

  - by Kev Hunter

  I am relatively new to using MSpec and as I write more and more tests it becomes obvious to reduce duplication you often have to use a base class for your setup as per Rob Conery's article I am happy with using the AssertWasCalled method to verify my expectations, but where do you set up a stub's return value, I find it useful to set the context in the base class injecting my dependencies but that (I think) means that I need to set my stubs up in the Because delegate which just feels wrong. Is there a better approach I am missing?
