  • Immutability of big objects

    - by Malax
    Hi StackOverflow! I have some big (more than 3 fields) Objects which can and should be immutable. Every time I run into that case i tend to create constructor abominations with long parameter lists. It doesn't feel right, is hard to use and readability suffers. It is even worse if the fields are some sort of collection type like lists. A simple addSibling(S s) would ease the object creation so much but renders the object mutable. What do you guys use in such cases? I'm on Scala and Java, but i think the problem is language agnostic as long as the language is object oriented. Solutions I can think of: "Constructor abominations with long parameter lists" The Builder Pattern Thanks for your input!

  • VB - Convert Web Site to Web Application

    - by Dave
    Hi This is my first time doing VB :-) I've inherited a web site, which I've converted into a web application in VS2008. The conversion has worked for everything except a Gallery control. The compile error I'm getting is: Type 'Gallery' is not defined in file: gallery_oct07.aspx.designer.vb Option Strict On Option Explicit On Partial Public Class gallery_oct07 '''<summary> '''Gallery1 control. '''</summary> '''<remarks> '''Auto-generated field. '''To modify move field declaration from designer file to code-behind file. '''</remarks> Protected WithEvents Gallery1 As Global.Gallery End Class with squiggly lines under Global.Gallery. The gallery_oct07.aspx.vb is: Partial Class gallery_oct07 Inherits System.Web.UI.Page End Class Gallery.ascx is: <%@ Control Language="C#" AutoEventWireup="true" Codebehind="Gallery.ascx.cs" Inherits="WebApplication1.Gallery"%> <asp:Repeater runat="server" ID="rptGallery"> <HeaderTemplate> <ul class='<%#CssClass%>'> </HeaderTemplate> <ItemTemplate> <li><a href='<%#ImageFolder + Eval("Name") %>' class="thickbox" rel="gallery"><img src='<%#ImageFolder + "thumb/" + Eval("Name") %>' /></a></li> </ItemTemplate> <FooterTemplate> </ul></FooterTemplate> </asp:Repeater> and the code behind is: using System; using System.IO; namespace WebApplication1 { public partial class Gallery : System.Web.UI.UserControl { public string _ImageFolder; public string ImageFolder { get { return _ImageFolder; } set { _ImageFolder = value; } } private string _cssClass = "gallery"; public string CssClass { get { return _cssClass; } set { _cssClass = value; } } protected void Page_Load(object sender, EventArgs e) { DirectoryInfo dir = new DirectoryInfo(MapPath(ImageFolder)); FileInfo[] images = dir.GetFiles("*.jpg"); rptGallery.DataSource = images; rptGallery.DataBind(); } protected void Page_PreRender(object sender, EventArgs e) { } } } The feels like a namespace issue.. My project namespace is WebApplication1. Cheers!

  • best option to create simple website mockup with navigation

    - by Buzzer
    I'm trying to put together a static html website with full navigation. In other words, I want the user to click some links and images and actually be taken to another page. I'm a developer so I know how to do this in frameworks like ASP.Net MVC and grails. However, for this particular case, I just want to quickly mock up the UI and provide simple navigation so I can do some user testing. Can anyone advice on how to do this? Thanks,

  • MVC pattern implementation. What is the n-relation between its components

    - by Srodriguez
    Dear all, I'm working in a C# project and we are , in order to get some unity across the different parts of our UI, trying to use the MVC pattern. The client is windows form based and I'm trying to create a simple MVC pattern implementation. It's been more challenging than expected, but I still have some questions regarding the MVC pattern. The problem comes mostly from the n-n relationships between its components: Here is what I've understood, but I'm not sure at all of it. Maybe someone can correct me? Model: can be shared among different Views. 1-n relationship between Model-View View: shows the state of the model. only one controller (can be shared among different views?). 1-1 relationship with the Model, 1-1 relationship with the controller Controller: handles the user actions on the view and updates the model. One controller can be shared among different views, a controller interacts only with one model? I'm not sure about the two last ones: Can a view have several controller? Or can a view share a controller with another view? Or is it only a 1:1 relationship? Can a controller handle several views? can it interact with several models? Also, I take advantage of this question to ask another MVC related question. I've suppressed all the synchronous calls between the different members of the MVC, making use of the events and delegates. One last call is still synchronous and is actually the most important one: The call between the view and the controller is still synchronous, as I need to know rather the controller has been able to handle the user's action or not. This is very bad as it means that I could block the UI thread (hence the client itself) while the controller is processing or doing some work. How can I avoid this? I can make use of the callback but then how do i know to which event the callback comes from? PS: I can't change the pattern at this stage, so please avoid answers of type "use MVP or MVVC, etc ;) Thanks!

  • SQL Server Constraints Across Tables

    - by chama
    I have a SQL Server database with an Apartment table (which has columns FloorNum and BuildingID) and an ApartmentBuilding table (with column NumFloors). Is there any way to set up a constraint (using the SQL Server UI) to check that Apartment.FloorNum is greater than ApartmentBuilding.NumFloors? I tried this: FloorNum > ApartmentBuilding.NumFloors but now I realize that I somehow have to join the columns on the BuildingID, but I have no idea how to do that within a constraint. Thanks for your help!

  • JavaScript returns Access Denied

    - by heeboir
    Hello, I'm running into a scenario where at random times I am getting "Access Denied" when executing javascript. It is not repeatable and occurs in random places of my application. There is not indication of what is causing it in the logs and I'm really at a loss on this. It seems to be UI problem only. However, there is no reason it should appear as I do not have any such permission checking to could be getting triggered. Thanks in advance

  • Is it possible to access a running instance of an app using JNA/JNI?

    - by Carlos Blanco
    I'm writing a test engine for a Java application that has some of the code written in C. This application uses JNI to access it's native part. In the engine I'm writing, I use Fest to control de UI and perform the tests. However, I,m blind when dealing with the part that is written in C. I wonder if I can use JNA or JNI to access the native part of the app. I believe that the fact that the application is already running is huge issue here.

    Has anyone taken the vmware certified professional exam? I was wondering if I can just take this class: http://mylearn1.vmware.com/mgrreg/courses.cfm?ui=www&a=one&id_subject=10103 or would I need to do additional studying on my own? I'm a developer with limited server experience. I'm aware of the technologies but haven't worked with them directly. Anyone that has taken the exam or has been in a similar situation, any insight would be appreciated.

  • What is the most elegant way to implement a business rule relating to a child collection in LINQ?

    - by AaronSieb
    I have two tables in my database: Wiki WikiId ... WikiUser WikiUserId (PK) WikiId UserId IsOwner ... These tables have a one (Wiki) to Many (WikiUser) relationship. How would I implement the following business rule in my LINQ entity classes: "A Wiki must have exactly one owner?" I've tried updating the tables as follows: Wiki WikiId (PK) OwnerId (FK to WikiUser) ... WikiUser WikiUserId (PK) WikiId UserId ... This enforces the constraint, but if I remove the owner's WikiUser record from the Wiki's WikiUser collection, I recieve an ugly SqlException. This seems like it would be difficult to catch and handle in the UI. Is there a way to perform this check before the SqlException is generated? A better way to structure my database? A way to catch and translate the SqlException to something more useful? Edit: I would prefer to keep the validation rules within the LINQ entity classes if possible. Edit 2: Some more details about my specific situation. In my application, the user should be able to remove users from the Wiki. They should be able to remove any user, except the user who is currently flagged as the "owner" of the Wiki (a Wiki must have exactly one owner at all times). In my control logic, I'd like to use something like this: wiki.WikiUsers.Remove(wikiUser); mRepository.Save(); And have any broken rules transferred to the UI layer. What I DON'T want to have to do is this: if(wikiUser.WikiUserId != wiki.OwnerId) { wiki.WikiUsers.Remove(wikiUser); mRepository.Save(); } else { //Handle errors. } I also don't particularly want to move the code to my repository (because there is nothing to indicate not to use the native Remove functions), so I also DON'T want code like this: mRepository.RemoveWikiUser(wiki, wikiUser) mRepository.Save(); This WOULD be acceptable: try { wiki.WikiUsers.Remove(wikiUser); mRepository.Save(); } catch(ValidationException ve) { //Display ve.Message } But this catches too many errors: try { wiki.WikiUsers.Remove(wikiUser); mRepository.Save(); } catch(SqlException se) { //Display se.Message } I would also PREFER NOT to explicitly call a business rule check (although it may become necessary): wiki.WIkiUsers.Remove(wikiUser); if(wiki.CheckRules()) { mRepository.Save(); } else { //Display broken rules }

  • Android: roatating images in a loop.

    - by user573736
    Hello, I am trying with no success to modify the code example from: http://www.inter-fuser.com/2009/08/android-animations-3d-flip.html so it will rotate the images in a loop, when clicking on the image once. (second click should pause). I tried using Handler and threading but cannot update the view since only the main thread can update UI. Exception I get from the code below: android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. [in 'image1.startAnimation(rotation);' ('applyRotation(0, 90);' from the main thread)] package com.example.flip3d; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.animation.AccelerateInterpolator; import android.widget.ImageView; public class Flip3d extends Activity { private ImageView image1; private ImageView image2; private boolean isFirstImage = true; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); image1 = (ImageView) findViewById(R.id.image01); image2 = (ImageView) findViewById(R.id.image02); image2.setVisibility(View.GONE); image1.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { if (isFirstImage) { applyRotation(0, 90); isFirstImage = !isFirstImage; } else { applyRotation(0, -90); isFirstImage = !isFirstImage; } } }); } private void applyRotation(float start, float end) { // Find the center of image final float centerX = image1.getWidth() / 2.0f; final float centerY = image1.getHeight() / 2.0f; // Create a new 3D rotation with the supplied parameter // The animation listener is used to trigger the next animation final Flip3dAnimation rotation = new Flip3dAnimation(start, end, centerX, centerY); rotation.setDuration(500); rotation.setFillAfter(true); rotation.setInterpolator(new AccelerateInterpolator()); rotation.setAnimationListener(new DisplayNextView(isFirstImage, image1, image2)); if (isFirstImage) { image1.startAnimation(rotation); } else { image2.startAnimation(rotation); } } } How can I manage to update the UI and control the rotation within onClick listener? Thank you, Oakist

  • Setting Grouping in UITableView under UINavigationController

    - by climbon
    In my UINavigationController app, my first view is a UITableView. I can't seem to find a way to set the property of this UITableView to 'grouped'. Since UITableView is dynamically generated I don't have the luxury of Interface Builder. Searched forums here and googled other places and closest I saw was to override either initWithStyle or initWithCoder as follows. (id)initWithStyle:(UITableViewStyle)style { if (self = [super initWithStyle:UITableViewStyleGrouped]) { } return self; } However this above function never gets called. when I overrided initWithCoder I could see it worked and I was able to change UITableView contents to grouped. But then title automatically became 'Root View Controller' and none of the cells were active anymore although they got grouped fine. That is while they looked active but if you click on them, those cells won't do anything. But I have seen apps which have their very first view being UITableView is grouped. So there must be a way to do it but I don't know how.

  • Referencing CDI producer method result in h:selectOneMenu

    - by user953217
    I have a named session scoped bean CustomerRegistration which has a named producer method getNewCustomer which returns a Customer object. There is also CustomerListProducer class which produces all customers as list from the database. On the selectCustomer.xhtml page the user is then able to select one of the customers and submit the selection to the application which then simply prints out the last name of the selected customer. Now this only works when I reference the selected customer on the facelets page via #{customerRegistration.newCustomer}. When I simply use #{newCustomer} then the output for the last name is null whenever I submit the form. What's going on here? Is this the expected behavior as according to chapter 7.1 Restriction upon bean instantion of JSR-299 spec? It says: ... However, if the application directly instantiates a bean class, instead of letting the container perform instantiation, the resulting instance is not managed by the container and is not a contextual instance as defined by Section 6.5.2, “Contextual instance of a bean”. Furthermore, the capabilities listed in Section 2.1, “Functionality provided by the container to the bean” will not be available to that particular instance. In a deployed application, it is the container that is responsible for instantiating beans and initializing their dependencies. ... Here's the code: Customer.java: @javax.persistence.Entity @Veto public class Customer implements Serializable, Entity { private static final long serialVersionUID = 122193054725297662L; @Column(name = "first_name") private String firstName; @Column(name = "last_name") private String lastName; @Id @GeneratedValue() private Long id; public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } @Override public String toString() { return firstName + ", " + lastName; } @Override public Long getId() { return this.id; } } CustomerListProducer.java: @SessionScoped public class CustomerListProducer implements Serializable { @Inject private EntityManager em; private List<Customer> customers; @Inject @Category("helloworld_as7") Logger log; // @Named provides access the return value via the EL variable name // "members" in the UI (e.g., // Facelets or JSP view) @Produces @Named public List<Customer> getCustomers() { return customers; } public void onCustomerListChanged( @Observes(notifyObserver = Reception.IF_EXISTS) final Customer customer) { // retrieveAllCustomersOrderedByName(); log.info(customer.toString()); } @PostConstruct public void retrieveAllCustomersOrderedByName() { CriteriaBuilder cb = em.getCriteriaBuilder(); CriteriaQuery<Customer> criteria = cb.createQuery(Customer.class); Root<Customer> customer = criteria.from(Customer.class); // Swap criteria statements if you would like to try out type-safe // criteria queries, a new // feature in JPA 2.0 // criteria.select(member).orderBy(cb.asc(member.get(Member_.name))); criteria.select(customer).orderBy(cb.asc(customer.get("lastName"))); customers = em.createQuery(criteria).getResultList(); } } CustomerRegistration.java: @Named @SessionScoped public class CustomerRegistration implements Serializable { @Inject @Category("helloworld_as7") private Logger log; private Customer newCustomer; @Produces @Named public Customer getNewCustomer() { return newCustomer; } public void selected() { log.info("Customer " + newCustomer.getLastName() + " ausgewählt."); } @PostConstruct public void initNewCustomer() { newCustomer = new Customer(); } public void setNewCustomer(Customer newCustomer) { this.newCustomer = newCustomer; } } not working selectCustomer.xhtml: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets"> <h:head> <title>Auswahl</title> </h:head> <h:body> <h:form> <h:selectOneMenu value="#{newCustomer}" converter="customerConverter"> <f:selectItems value="#{customers}" var="current" itemLabel="#{current.firstName}, #{current.lastName}" /> </h:selectOneMenu> <h:panelGroup id="auswahl"> <h:outputText value="#{newCustomer.lastName}" /> </h:panelGroup> <h:commandButton value="Klick" action="#{customerRegistration.selected}" /> </h:form> </h:body> </html> working selectCustomer.xhtml: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets"> <h:head> <title>Auswahl</title> </h:head> <h:body> <h:form> <h:selectOneMenu value="#{customerRegistration.newCustomer}" converter="customerConverter"> <f:selectItems value="#{customers}" var="current" itemLabel="#{current.firstName}, #{current.lastName}" /> </h:selectOneMenu> <h:panelGroup id="auswahl"> <h:outputText value="#{newCustomer.lastName}" /> </h:panelGroup> <h:commandButton value="Klick" action="#{customerRegistration.selected}" /> </h:form> </h:body> </html> CustomerConverter.java: @SessionScoped @FacesConverter("customerConverter") public class CustomerConverter implements Converter, Serializable { private static final long serialVersionUID = -6093400626095413322L; @Inject EntityManager entityManager; @Override public Object getAsObject(FacesContext context, UIComponent component, String value) { Long id = Long.valueOf(value); return entityManager.find(Customer.class, id); } @Override public String getAsString(FacesContext context, UIComponent component, Object value) { return ((Customer) value).getId().toString(); } }
