  • Localized tables and Entity Framework

    - by Pyttroll
    Hi all, I have a scenario where I need to localized values of objects in my database. Let's say you have an application that can create animals, if the user is english the value of the "Name" property of an animal would be entered as "Cat" in the UI whereas it would be entered as "Chat" in french. The animal culture table would contain 2 records pointing to the same animal in the parent table. When reading values back, if the value of "Name" does not exist in the user culture the default value (value the object was originally created with) would be used. The following diagrams demonstrate how the data is stored in SQL: I'm trying to map this schema to an object model using the Entity Framework, I'm a bit confused as to what the best way to approach the problem. Is EF appropriate for this? Should I used EF4? This EF model will be used by .NET RIA Services. Thanks, Pierre-Yves Troel Ayuda Media Systems http://www.ayudasystems.com

  • How to create tests for poco objects

    - by Simon G
    Hi, I'm new to mocking/testing and wanting to know what level should you go to when testing. For example in my code I have the following object: public class RuleViolation { public string ErrorMessage { get; private set; } public string PropertyName { get; private set; } public RuleViolation( string errorMessage ) { ErrorMessage = errorMessage; } public RuleViolation( string errorMessage, string propertyName ) { ErrorMessage = errorMessage; PropertyName = propertyName; } } This is a relatively simple object. So my question is: Does it need a unit test? If it does what do I test and how? Thanks

  • Do I need to include the 'this' when using a property name in a closure?

    - by Scott Whitlock
    I'm using a list of Actions to store an undo history for an object. Let's say I have a property of my object called myChildObject and it's being changed, so I want to store the undo action where I would set it back to it's current value: public class Class1 { public Class1() { } private readonly List<Action> m_undoActions = new List<Action>(); private SomeObject myChildObject { get; set; } public void ChangeState(SomeObject newChildObject) { // copies the reference SomeObject existingObject = myChildObject; m_undoActions.Add(() => myChildObject = existingObject); myChildObject = newChildObject; } } Looking at the lambda expression, existingObject is a local variable, so it's using a closure to pass a reference to that variable, but what about the property myChildObject? Do I need to use 'this' to preface it? Do I need to make a copy of the 'this' reference to a local variable first? Thanks for helping me understand this closure stuff.

  • Do I need to Dispose to deregister events?

    - by Sean
    Say I have two classes, and neither of them are GUI components. Class A is a short lived object that registers for an event declared by a long lived object B. For example public A(B b) { b.ChangeEvent += OnChangeEvent; } If A never deregisters from B's event, will A never be garbage collected? Does A need a Dispose method just to deregister from B's event? There is also a related second question. If A and B should both live for the entire execution time of the application, does A need to deregister?

  • Wordpress: Sort posts by meta value after AFTER querying from database

    - by Joseph Carrington
    Hello, I am pulling posts from my database by using Wordpress' WP_Query object like so: $shows_query = new WP_Query("category_name=shows&meta_key=band&meta_value=$artist_id"); I have another meta value I would like to sort the posts by, however. The meta key is 'date'. The WP_Query object can no work with multiple meta_keys, so this does not work: $shows_query = new WP_Query("category_name=shows&meta_key=band&meta_value=$artist_id&meta_key=date&orderby=meta_value&order=DESC"); So now I have to figure out a way to sort the posts in $shows_query['posts'] by one of their meta_values, which are not even IN their array. Any other, more sensible approach would also be appreciated.

  • Does the WCF framework support the XSD IDREF restriction?

    - by Gerard
    A nice feature in XSD is the IDREF restriction, e.g.: <xs:restriction base="xs:IDREF"> <xs:pattern value="[0-9a-zA-Z\-]+"/> </xs:restriction> I used this restriction with great benefit in a Java JAXWS-project. An object serialized in a SOAP XML datamodel can hold a reference (pointer) to another object in the same SOAP message. I want to try the same approach in a C# WCF-project, can it be done? On the web site Data Contract Schema Reference I can see e.g. Id ignored, Ref forbidden, but I am not sure whether I understand what that means.

  • Invoking play on a QTMovie causes screensaver to deactivate on Snow Leopard

    - by ressaw
    I'm trying to port a working Leopard screensaver to Snow Leopard but it's deactivating after about half a second. The screensaver seems to deactivate upon invoking play on a QTMovie. And it deactivates both upon -play on the QTMovie object itself, and -play:self on the QTMovieView. If I don't actually call -play on the object, the screensaver does not deactivate and sits still on the first frame of the movie. Setting up the same code in a regular Cocoa Application works fine, and the screensaver also works fine in preview mode in the System Preferences. Any help is greatly appreciated.

  • NotifyIcon behaviour on Windows 7 with MouseClick, MouseDoubleClick events

    - by binball
    I have strange behaviour with my app after run it on Windows 7. It's connected with NotifyIcon while app is minimized. What should happens: 1) Click once on icon with mouse left button then Balloon with some text should appears 2) Double click on icon will show again app window On Windows 7 MouseDoubleClick is also fired but window is not showing. I don't know why. The same code works good on Windows XP. private void notifyIcon_MouseClick(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { this.NotifyIconShowBalloonWithData(); } } private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e) { this.Show(); WindowState = FormWindowState.Normal; notifyIcon.Visible = false; } What did I wrong? :)

  • Do a database query on Textbox onblur event

    - by user279521
    I am using asp.net 3.5 with C#. I need to do a database lookup when a user enters ProductID in txtProductID. I guess doing javascript is out of the question since this will have to be server side call. I wrote this code in the page_load event of the webpage: protected void Page_Load(object sender, EventArgs e) { txtProductID.Attributes.Add("onblur", "LookupProduct()"); } protected void LookupUser() { //Lookup Product information on onBlur event; } I get an error message: Microsoft JScript runtime error: Object expected How can I resolve this ?

  • Cast an instance of a class to a @protocol in Objective-C

    - by Ford
    I have an object (a UIViewController) which may or may not conform to a protocol I've defined. I know I can determine if the object conforms to the protocol, then safely call the method: if([self.myViewController conformsToProtocol:@protocol(MyProtocol)]) { [self.myViewController protocolMethod]; // <-- warning here } However, XCode shows a warning: warning 'UIViewController' may not respond to '-protocolMethod' What's the right way to prevent this warning? I can't seem to cast self.myViewController as a MyProtocol class. Update Andy's answer below is close, but includes an unneccesary '*'. The following works: [(id<MyProtocol>)self.myViewController protocolMethod];

  • How to convert a DOM node list to an array in Javascript?

    - by Guss
    I have a Javascript function that accepts a list of HTML nodes, but it expects a Javascript array (it runs some Array methods on that) and I want to feed it the output of Document.getElementsByTagName that returns a DOM node list. Initially I thought of using something simple like: Array.prototype.slice.call(list,0) And that works fine in all browsers, except of course Internet Explorer which returns the error "JScript object expected", as apparently the DOM node list returned by Document.getElement* methods is not a JScript object enough to be the target of a function call. Caveats: I don't mind writing Internet Explorer specific code, but I'm not allowed to use any Javascript libraries such as JQuery because I'm writing a widget to be embedded into 3rd party web site, and I cannot load external libraries that will create conflict for the clients. My last ditch effort is to iterate over the DOM node list and create an array myself, but is there a nicer way to do that?

  • deadlock when using WCF Duplex Polling with Silverlight

    - by Kobi Hari
    Hi all. I have followed Tomek Janczuk's demonstration on silverlight tv to create a chat program that uses WCF Duplex Polling web service. The client subscribes to the server, and then the server initiates notifications to all connected clients to publish events. The Idea is simple, on the client, there is a button that allows the client to connect. A text box where the client can write a message and publish it, and a bigger text box that presents all the notifications received from the server. I connected 3 clients (in different browsers - IE, Firefox and Chrome) and it all works nicely. They send messages and receive them smoothly. The problem starts when I close one of the browsers. As soon as one client is out, the other clients get stuck. They stop getting notifications. I am guessing that the loop in the server that goes through all the clients and sends them the notifications is stuck on the client that is now missing. I tried catching the exception and removing it from the clients list (see code) but it still does not help. any ideas? The server code is as follows: using System; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.ServiceModel.Activation; using System.Collections.Generic; using System.Runtime.Remoting.Channels; namespace ChatDemo.Web { [ServiceContract] public interface IChatNotification { // this will be used as a callback method, therefore it must be one way [OperationContract(IsOneWay=true)] void Notify(string message); [OperationContract(IsOneWay = true)] void Subscribed(); } // define this as a callback contract - to allow push [ServiceContract(Namespace="", CallbackContract=typeof(IChatNotification))] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] [ServiceBehavior(InstanceContextMode=InstanceContextMode.Single)] public class ChatService { SynchronizedCollection<IChatNotification> clients = new SynchronizedCollection<IChatNotification>(); [OperationContract(IsOneWay=true)] public void Subscribe() { IChatNotification cli = OperationContext.Current.GetCallbackChannel<IChatNotification>(); this.clients.Add(cli); // inform the client it is now subscribed cli.Subscribed(); Publish("New Client Connected: " + cli.GetHashCode()); } [OperationContract(IsOneWay = true)] public void Publish(string message) { SynchronizedCollection<IChatNotification> toRemove = new SynchronizedCollection<IChatNotification>(); foreach (IChatNotification channel in this.clients) { try { channel.Notify(message); } catch { toRemove.Add(channel); } } // now remove all the dead channels foreach (IChatNotification chnl in toRemove) { this.clients.Remove(chnl); } } } } The client code is as follows: void client_NotifyReceived(object sender, ChatServiceProxy.NotifyReceivedEventArgs e) { this.Messages.Text += string.Format("{0}\n\n", e.Error != null ? e.Error.ToString() : e.message); } private void MyMessage_KeyDown(object sender, KeyEventArgs e) { if (e.Key == Key.Enter) { this.client.PublishAsync(this.MyMessage.Text); this.MyMessage.Text = ""; } } private void Button_Click(object sender, RoutedEventArgs e) { this.client = new ChatServiceProxy.ChatServiceClient(new PollingDuplexHttpBinding { DuplexMode = PollingDuplexMode.MultipleMessagesPerPoll }, new EndpointAddress("../ChatService.svc")); // listen for server events this.client.NotifyReceived += new EventHandler<ChatServiceProxy.NotifyReceivedEventArgs>(client_NotifyReceived); this.client.SubscribedReceived += new EventHandler<System.ComponentModel.AsyncCompletedEventArgs>(client_SubscribedReceived); // subscribe for the server events this.client.SubscribeAsync(); } void client_SubscribedReceived(object sender, System.ComponentModel.AsyncCompletedEventArgs e) { try { Messages.Text += "Connected!\n\n"; gsConnect.Color = Colors.Green; } catch { Messages.Text += "Failed to Connect!\n\n"; } } And the web config is as follows: <system.serviceModel> <extensions> <bindingExtensions> <add name="pollingDuplex" type="System.ServiceModel.Configuration.PollingDuplexHttpBindingCollectionElement, System.ServiceModel.PollingDuplex, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> </bindingExtensions> </extensions> <behaviors> <serviceBehaviors> <behavior name=""> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> </behaviors> <bindings> <pollingDuplex> <binding name="myPollingDuplex" duplexMode="MultipleMessagesPerPoll"/> </pollingDuplex> </bindings> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/> <services> <service name="ChatDemo.Web.ChatService"> <endpoint address="" binding="pollingDuplex" bindingConfiguration="myPollingDuplex" contract="ChatDemo.Web.ChatService"/> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> </system.serviceModel>

  • control panel date&time is considered while using "new date()" javascript function.

    - by Rupa
    Hi, I am getting a client date in javscript function using "new date()" object. But this object is considering the properties set for Date&Time control in the control panel of the system. For example, If I check the check box of Date&Time control of the system (control panel) "Automatically adjust clock for daylight saving changes", then I am getting the date(from javscript) according to the Daylight savings time and if I uncheck it, I am getting the date according to the standard time. What I need is to get the date from a Javscript function irrespective of the Date&Time control of the control panel. Thanks Rupa.

  • How do I do automatic data serialization of data objects in Haskell

    - by Adam Gent
    One of the huge benefits in languages that have some sort of reflection/introspecition is that objects can be automatically constructed from a variety of sources. For example in Java I can use the same objects for persisting to a db (with Hibernate) serializing to XML (with JAXB) or serializing to JSON (json-lib). You can do the same in Ruby and Python also usually following some simple rules for properties or annotations for Java. Thus I don't need lots "Domain Transfer Objects". I can concentrate on the domain I am working in. It seems in very strict FP like Haskell and Ocaml this is not possible. Particularly Haskell. The only thing I have seen is doing some sort of preprocessing or meta-programming (ocaml). Is it just accepted that you have to do all the transformations from the bottom upwards? In other words you have to do lot of boring work to turn a data type in haskell into JSON/XML/DB Row object and back again into a data object.

  • Specification: Use cases for CRUD

    - by Mario Ortegón
    I am writing a Product requirements specification. In this document I must describe the ways that the user can interact with the system in a very high level. Several of these operations are "Create-Read-Update-Delete" on some objects. The question is, when writing use cases for these operations, what is the right way to do so? Can I write only one Use Case called "Manage Object x" and then have these operations as included Use Cases? Or do I have to create one use case per operation, per object? The problem I see with the last approach is that I would be writing quite a few pages that I feel do not really contribute to the understanding of the problem. What is the best practice?

  • JPopupMenu getParent() returning a null?

    - by Zenzen
    Ok so I'm working on an Eclipse plugin based on the JGraph example. The problem is I can't really get the "save" method to work, here's how the program works in short: - I have a DiagramEditor class with an init() method, where I create a GraphEditor object and call the createFrame() methord of that object. - GraphEditor extends the BasicGraphEditor (which extends JPanel), the createFrame() method returns a JFrame and has a line "frame.setJMenuBar(menuBar)" - the "menuBar" is an object variable, which is initialized in the BasicGraphEditor. Till here everything is cool, the problem is with the action listener which is supposed to save a file. To get the graph I need to get the GraphEditor component, so I do a Component component = (Component) e.getSource() whitch is the ActionEvent passed to that action listener and at that stage is the JMenuItem "save", then I get the parent which is the JPopupMenu, then I want to get that JPopupMenu's parent which should be the GraphEdiotor, but instead I get a null. Any idea why? Here's some source code: DiagramEditor.java: @Override public void init(IEditorSite site, IEditorInput input) throws PartInitException { setSite(site); setInput(input); this.diagram = ((DiagramEditorInput)input).getDiagram(); setPartName(this.diagram.getName()); gEditor = new GraphEditor(); gEditor.createFrame().setVisible(true); } BasicGraphEditor.java: public JFrame createFrame() { JFrame frame = new JFrame(); frame.getContentPane().add(this); frame.setJMenuBar(menuBar); //frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(870, 640); return frame; } In the constructor: menuBar = new JMenuBar(); menu = new JMenu("File"); menu.setMnemonic(KeyEvent.VK_F); menuBar.add(menu); JMenuItem openMenuItem = new JMenuItem("Open", KeyEvent.VK_O); // ADD FILE OPENING //openMenuItem.addActionListener(menuListener); menu.add(openMenuItem); JMenuItem saveMenuItem = new JMenuItem("Save", new ImageIcon("/images/save.gif")); saveMenuItem.setMnemonic(KeyEvent.VK_S); saveMenuItem.addActionListener( new SaveAction(false) ); menu.add(saveMenuItem); // menu.add(new SaveAction(false)); JMenuItem saveMenuItemAs = new JMenuItem("SaveAs", new ImageIcon("/images/saveas.gif")); //saveMenuItemAs.setMnemonic(KeyEvent.VK_S); saveMenuItemAs.addActionListener( new SaveAction(true) ); menu.add(saveMenuItemAs); //menu.add(new SaveAction(true)); JMenuItem closeMenuItem = new JMenuItem("Close", KeyEvent.VK_C); closeMenuItem.addActionListener( new ActionListener() { public void actionPerformed(ActionEvent e) { System.exit(0); } } ); menu.add(closeMenuItem);

  • Find all clauses related to an atom

    - by Luc Touraille
    This is probably a very silly question (I just started learning Prolog a few hours ago), but is it possible to find all the clauses related to an atom? For example, assuming the following knowledge base: cat(tom). animal(X) :- cat(X). , is there a way to obtain every possible information about tom (or at least all the facts that are explicitly stated in the base)? I understand that a query like this is not possible: ?- Pred(tom). so I thought I could write a rule that would deduce the correct information: meta(Object, Predicate) :- Goal =.. [Predicate, Object], call(Goal). so that I could write queries such as ?- meta(tom, Predicate). but this does not work because arguments to call are not sufficiently instantiated. So basically my question is: is this at all possible, or is Prolog not design to provide this kind of information? And if it is not possible, why?

  • Accessing Linq data in telerik grid ItemCreated method

    - by Jack
    Not sure if the title of this question makes sense, but here's my problem: I have a telerik grid bound to a Linq data object, however, I limit the fields returned: <IQueryable>filter = data.Select(x => new {x.ID, x.Name, x.Age}); I would like to access these fields in the ItemCreated method of the grid: protected void rgPeople_ItemCreated(object sender, GridItemEventArgs e) { Telerik.Web.UI.GridDataItem item = (GridDataItem)e.Item; ?????? Person = (???????)e.Item.DataItem; } What do I declare ?????? as so that I can use: String ID = Person.ID; String Name = Person.Name; etc

  • Structure accessible by attribute name or index options

    - by Bruno DeGoia
    I am very new to Python, and trying to figure out how to create an object that has values that are accessible either by attribute name, or by index. For example, the way os.stat() returns a stat_result or pwd.getpwnam() returns a struct_passwd. In trying to figure it out, I've only come across C implementations of the above types. Nothing specifically in Python. What is the Python native way to create this kind of object? I apologize if this has been widely covered already. In searching for an answer, I must be missing some fundamental concept that is excluding me from finding an answer.

  • Consecutive 'if' statements

    - by Ben Packard
    How can I check one thing AND THEN another, if the first is true? For example, say I have a shopping basket object, and I only want to do something if the basket has been created AND it isn't empty. I've tried: if (basket && [basket numberOfItems >0])... But the second condition is evaluated even if the first fails, resulting in a crash (presumably because i'm calling numberOfItems on an object that doesn't exist). I can nest them, but this seems a bit ugly, and more to the point is problematic. Say I want to do one thing if the basket exists AND isn't empty, but another if either isn't true. That doesn't really work well in nested if statements.
