  • Nested Resource testing RSpec

    - by Joseph DelCioppio
    I have two models: class Solution < ActiveRecord::Base belongs_to :owner, :class_name => "User", :foreign_key => :user_id end class User < ActiveRecord::Base has_many :solutions end with the following routing: map.resources :users, :has_many => :solutions and here is the SolutionsController: class SolutionsController < ApplicationController before_filter :load_user def index @solutions = @user.solutions end private def load_user @user = User.find(params[:user_id]) unless params[:user_id].nil? end end Can anybody help me with writing a test for the index action? So far I have tried the following but it doesn't work: describe SolutionsController do before(:each) do @user = Factory.create(:user) @solutions = 7.times{Factory.build(:solution, :owner => @user)} @user.stub!(:solutions).and_return(@solutions) end it "should find all of the solutions owned by a user" do @user.should_receive(:solutions) get :index, :user_id => @user.id end end And I get the following error: Spec::Mocks::MockExpectationError in 'SolutionsController GET index, when the user owns the software he is viewing should find all of the solutions owned by a user' #<User:0x000000041c53e0> expected :solutions with (any args) once, but received it 0 times Thanks in advance for all the help.

  • ListView setOnItemClickListener in ListFragment not working

    - by Siddarth Kaki
    I am developing an app that uses ActionBar tabs to display a list of options through ListFragment. The list (and ListFragment) display without a problem, but the ListView's setOnItemClickListener doesn't seems to work, as nothing happens when an item in the list is clicked. Here's the code for the ListFragment class: package XXX.XXX; public class AboutFrag extends SherlockListFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.aboutfrag, container, false); ListView lv = (ListView) view.findViewById(android.R.id.list); String[] items = new String[] {"About 1", "About 2", "About 3"}; lv.setAdapter(new ArrayAdapter<String>(getActivity(), R.layout.list_item, items)); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { switch (position) { case 0: Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://google.com")); startActivityForResult(browserIntent, 0); break; case 1: Intent browserIntent2 = new Intent(Intent.ACTION_VIEW, Uri.parse("http://wikipedia.org")); startActivityForResult(browserIntent2, 0); break; case 2: Intent browserIntent3 = new Intent(Intent.ACTION_VIEW, Uri.parse("http:/android.com"); startActivityForResult(browserIntent3, 0); break; } } }); return view; } } I'm assuming it does not work because the class returns the view object, so the FragmentActivity can't run the listener code, so does anyone know how to make this work? By the way, I am using ActionBarSherlock. Thanks in advance!!!

  • Why does the entity framework need an ICollection for lazy loading?

    - by Akk
    I want to write a rich domain class such as public class Product { public IEnumerable<Photo> Photos {get; private set;} public void AddPhoto(){...} public void RemovePhoto(){...} } But the entity framework (V4 code first approach) requires an ICollection type for lazy loading! The above code no longer works as designed since clients can bypass the AddPhoto / RemovePhoto method and directly call the add method on ICollection. This is not good. public class Product { public ICollection<Photo> Photos {get; private set;} //Bad public void AddPhoto(){...} public void RemovePhoto(){...} } It's getting really frustrating trying to implement DDD with the EF4. Why did they choose the ICollection for lazy loading? How can i overcome this? Does NHibernate offer me a better DDD experience?

  • What's the difference between DI and factory patterns?

    - by Anthony Short
    I have a class which depends on 3 classes, all 3 of which have other classes they rely on. Currently, I'm using a container class to build up all the required classes, inject them into one another and return the application. The simplified version of the container looks something like this: class Builder { private $_options; public function __construct($options) { $this->_options = $options; } public function build() { $cache = $this->getCache(); $response = $this->getResponse(); $engine = $this->getEngine(); return new Application($cache,$response,$engine); } public function getResponse() { $encoder = $this->getResponseEncoder(); $cache = $this->getResponseCache(); return new Response($encoder,$cache); } // Methods for building each object } I'm not sure if this would be classified as FactoryMethod or a DI Container. They both seem to solve the same problem in the same way - They build objects and inject dependencies. This container has some more complicated building methods, like loading observers and attaching them to observable objects. Should factories be doing all the building (loading extensions etc) and the DI container should use these factories to inject dependencies? That way the sub-packages, like Cache, Response etc, can each have their own specialised factories.

  • Is there a definitive reference document for Ruby syntax?

    - by JSW
    I'm searching for a definitive document on Ruby syntax. I know about the definitive documents for the core API and standard library, but what about the syntax itself? For instance, such a document should cover: reserved words, string literals syntax, naming rules for variables/classes/modules, all the conditional statements and their permutations, and so forth. I know there are many books and tutorials, yes, but every one of them is essentially a tutorial, each one having a range of different depth and focus. They will all, by necessity of brevity and narrative flow, omit certain details of the language that the author deems insignificant. For instance, did you know that you can use a case statement without an initial case value, and it will then execute the first true when clause? Any given Ruby book or tutorial may or may not cover that particular lesser-known functionality of the case syntax. It's not discussed in the section in "Programming Ruby" about case statements. But that is just one small example. So far the best documentation I've found is the rubyspec project, which appears to be an attempt to write a complete test suite for the language. That's not bad, but it's a bit hard to use from a practical standpoint as a developer working on my own projects. Am I just missing something or is there really no definitive readable document defining the whole of Ruby syntax?

  • How to read a parameter passed to a facelet from a backing bean

    - by Antonio
    Hi, I've written a facelet, and a corresponding backing bean, that implements user management (addition, deletion and so on). I'd want to be able to perform some custom processing when, for instance, a new user is added. There is a "create" button in the facelet, whose click event is handled by its backing bean. At the end of the event handler, I'd want to be able to call a method of another backing bean, which is not known because ideally the facelet can be used in several pages, with different custom processing. I thought to implement this feature by providing to the facelet a backing bean name and a method name, like this: <myfacelet:subaccounts backingBean="myBackingBean" createListener="createListener" /> and at the end of the event handler call #{myBackingBean.createListener} someway. I'm using this method (along with some overloads) to obtain a MethodExpression: protected MethodExpression getMethodExpression(String beanName, String methodName, Class<?> expectedReturnType, Class<?>[] expectedParamTypes) { ExpressionFactory expressionFactory; MethodExpression method; ELContext elContext; String el; el = String.format("#{%s['%s']}", beanName, methodName); expressionFactory = getApplication().getExpressionFactory(); elContext = getFacesContext().getELContext(); method = expressionFactory.createMethodExpression(elContext, el, expectedReturnType, expectedParamTypes); return method; } and the click event handler should look like: public void saveSubaccountListener(ActionEvent event) { MethodExpression method; ... method = getMethodExpression( "backingBean", "createSubaccountListener", SubuserBean.class); if (method != null) method.invoke( getFacesContext().getELContext(), new Object[] { _editedSubuser }); } That works fine as long as I provide an existing bean name (myBackingBean), but if I use backingBean the invoke() doesn't work due to the following error: javax.el.PropertyNotFoundException: Target Unreachable, identifier 'backingBean' resolved to null Is there a way I can retrieve from the facelet backing bean the value of a parameter that has been passed to the facelet? In my case, the value of backingBean, which should be myBackingBean? I've searched for and tried different solutions, but with no luck yet.

  • Ordering by Sum from a separate controller part 2

    - by bgadoci
    Ok, so I had this working just fine before making a few controller additions and the relocation of some code. I feel like I am missing something really simple here but have spent hours trying to figure out what is going on. Here is the situation. class Question < ActiveRecord::Base has_many :sites end and class Sites < ActiveRecord::Base belongs_to :questions end I am trying to display my Sites in order of the sum of the 'like' column in the Sites Table. From my previous StackOverflow question I had this working when the partial was being called in the /views/sites/index.html.erb file. I then moved the partial to being called in the /views/questions/show.html.erb file and it successfully displays the Sites but fails to order them as it did when being called from the Sites view. I am calling the partial from the /views/questions/show.html.erb file as follows: <%= render :partial => @question.sites %> and here is the SitesController#index code class SitesController < ApplicationController def index @sites = @question.sites.all(:select => "sites.*, SUM(likes.like) as like_total", :joins => "LEFT JOIN likes AS likes ON likes.site_id = sites.id", :group => "sites.id", :order => "like_total DESC") respond_to do |format| format.html # index.html.erb format.xml { render :xml => @sites } end end

  • Formating a table date field from the Model in Codeigniter

    - by Landitus
    Hi, I', trying to re-format a date from a table in Codeigniter. The Controller is for a blog. I was succesfull when the date conversion happens in the View. I was hoping to convert the date in the Model to have things in order. Here's the date conversion as it happens in the View. This is inside the posts loop: <?php foreach($records as $row) : ?> <?php $fdate = "%d <abbr>%M</abbr> %Y"; $dateConv = mdate($fdate, mysql_to_unix($row->date)); ?> <div class="article section"> <span class="date"><?php echo $dateConv ;?></span> ... Keeps going ... This is the Model: class Novedades_model extends Model { function getAll() { $this->db->order_by('date','desc'); $query = $this->db->get('novedades'); if($query->num_rows() > 0) { foreach ($query->result() as $row) { $data[] = $row; } } return $data; } } How can I convert the date in the Model? Can I access the date key and refactor it?

  • Consistent HashCode() and Equals() results, but inconsistent TreeMap.containsKey() result

    - by smessing
    I have the following object Node: private class Node implements Comparable<Node>(){ private String guid(); ... public boolean equals(Node o){ return (this == o); } public int hashCode(){ return guid.hashCode(); } ... } And I use it in the following TreeMap: TreeMap<Node, TreeSet<Edge>> nodes = new TreeMap<Node, TreeSet<Edge>>(); Now, the tree map is used in a class called Graph to store nodes currently in the graph, along with a set of their edges (from the class Edge). My problem is when I try to execute: public containsNode(n){ for (Node x : nodes.keySet()) { System.out.println("HASH CODE: "); System.out.print(x.hashCode() == n.hashCode()); System.out.println("EQUALS: "); System.out.print(x.equals(n)); System.out.println("CONTAINS: "); System.out.print(nodes.containsKey(n)); System.out.println("N: " + n); System.out.println("X: " + x); } } I sometimes get the following: HASHCODE: true EQUALS: true CONTAINS: false N: foo X: foo Anyone have an idea as to what I'm doing wrong? I'm still new to all this, so I apologize in advance if I'm overlooking something simple (I know hashCode() doesn't really matter for TreeMap, but I figured I'd include it).

  • AddEvenLister fires off immediately after being attached

    - by Diego
    I want to know how to correctly add an Event Listener like onClick to a dynamic div. Here’s my snippet: var $menu = new Array(2); createDiv('yes'); function createDiv(title) { var $class = 'menuLink'; var $title = 'title'; for(var i=0; i<$menu.length;i++) { $title = 'title'; var newdiv = document.createElement('div'); newdiv.setAttribute('class', $class); newdiv.setAttribute('id', 'item'+i); newdiv.addEventListener('onclick', clickHandle(newdiv.id),false); if (title) { newdiv.innerHTML = $title; } else { newdiv.innerHTML = "No Title"; } document.getElementById('menu').appendChild(newdiv); showMenu(); } } function clickHandle(e) { if(e == 'item0') { alert('Link is' + ' ' + e); }else{ alert('Another Link'); } } Here's my problem, the snippet works fine, It creates my divs, adds id's values and all, but the event fires off as soon as the event is attached, so while the for loop is creating the divs the alert window says: Link is item0, and immediately after this it says: Another Link. Am I misunderstanding this? (I used this method zillions of times in AS3 with the expected result, just attached a function waiting for a click). What I want is that my Divs wait for the user to click on them, not to fire off immediately after of being attached. Thanks for any hint on this one. Greetings. Ps. IE doesn't support addEventListener, but I want to resolve this before cross to the IE sea of madness, but I will appreciate the IE approach as well. - I tried "onclick" and just 'click' into the addEventListener line, both with the same result described above.

  • Using a join with three tables when a field might be null

    - by John
    Hello, The code below works great. It combines data from two MySQL tables. I would like to modify it by pulling in some data from a third MySQL table called "comment." In the HTML table below, "title" is a field in the MySQL table "submission." Every "title" has a corresponding "submissionid" field. The field "submissionid" is also found in the "comment" MySQL table. In the HTML table below, I would like "countComments" to equal the number of times a field called "commentid" appears in the MySQL table "comment" for any given "submissionid," where the "submissionid" is the same in both the "submission" and "comment" tables, and where the "submissionid" corresponds to the "title" being used. Here's the catch: if there is no row in the MySQL table "comment" that corresponds with the "submissionid" being used for "table", I would like "countComments" to equal to zero. How can I do this? Thanks in advance, John $sqlStr = "SELECT s.loginid, s.title, s.url, s.displayurl, l.username FROM submission AS s, login AS l WHERE s.loginid = l.loginid ORDER BY s.datesubmitted DESC LIMIT 10"; $result = mysql_query($sqlStr); $arr = array(); echo "<table class=\"samplesrec\">"; while ($row = mysql_fetch_array($result)) { echo '<tr>'; echo '<td class="sitename1"><a href="http://www.'.$row["url"].'">'.$row["title"].'</a></td>'; echo '</tr>'; echo '<tr>'; echo '<td class="sitename2"><a href="http://www...com/sandbox/members/index.php?profile='.$row["username"].'">'.$row["username"].'</a><a href="http://www...com/sandbox/comments/index.php?submission='.$row["title"].'">'.$row["countComments"].'</a></td>'; echo '</tr>'; } echo "</table>";

  • Display: table-cell problems in chrome

    I have 3 divs that I would like to display as table cells: <div class="field"> <div class="row"> <label for="name">Subdomain</label> <input type="text" id="name" name="name"> <div class="subdomain-base ">test</div> </div> </div> This is the CSS that I am using: body{ font-size: 13px; } .field { width:450px; display: table; } .row { display: table-row; width: 100%; } .row > * { display: table-cell; border: 1px solid red; } label { width: 125px; height: 18px; } input { max-width: none; min-width: 0; overflow: auto; height: 18px; width: 100%; } .subdomain-base { height: 18px; width: 1px; } .subdomain-base { color: blue; font-size: 13px; } It works perfectly in Firefox 24: However, it has a height problem in Chrome 30 (latest): I have been trying all sorts of things to fix the problem with Chrome, but it seems like nothing works. Why is chrome getting that extra height? Jsfiddle: http://jsfiddle.net/ahLMH/

  • Django extending user model and displaying form

    - by MichalKlich
    Hello, I am writing website and i`d like to implement profile managment. Basic thing would be to edit some of user details by themself, like first and last name etc. Now, i had to extend User model to add my own stuff, and email address. I am having troubles with displaying form. Example will describe better what i would like achieve.

  • How to decide between using PLINQ and LINQ at runtime?

    - by Hamish Grubijan
    Or decide between a parallel and a sequential operation in general. It is hard to know without testing whether parallel or sequential implementation is best due to overhead. Obviously it will take some time to train "the decider" which method to use. I would say that this method cannot be perfect, so it is probabilistic in nature. The x,y,z do influence "the decider". I think a very naive implementation would be to give both 1/2 chance at the beginning and then start favoring them according to past performance. This disregards x,y,z, however. I suspect that this question would be better answered by academics than practitioners. Anyhow, please share your heuristic, your experience if any, your tips on this. Sample code: public interface IComputer { decimal Compute(decimal x, decimal y, decimal z); } public class SequentialComputer : IComputer { public decimal Compute( ... // sequential implementation } public class ParallelComputer : IComputer { public decimal Compute( ... // parallel implementation } public class HybridComputer : IComputer { private SequentialComputer sc; private ParallelComputer pc; private TheDecider td; // Helps to decide between the two. public HybridComputer() { sc = new SequentialComputer(); pc = new ParallelComputer(); td = TheDecider(); } public decimal Compute(decimal x, decimal y, decimal z) { decimal result; decimal time; if (td.PickOneOfTwo() == 0) { // Time this and save result into time. result = sc.Compute(...); } else { // Time this and save result into time. result = pc.Compute(); } td.Train(time); return result; } }

  • Need an advice for unit testing using mock object

    - by Andree
    Hi there, I just recently read about "Mocking objects" for unit testing and currently I'm having a difficulties implementing this approach in my application. Please let me explain my problem. I have a User model class, which is dependent on 2 data sources (database and facebook web service). The controller class simply use this User model as an interface to access data and it doesn't care about where the data came from. Currently I never done any unit test to this User model because it is dependent on an external web service. But just a while ago, I read about object mocking and now I know that it is a common approach to unit test a class that depends on external resources (like in my case). Now I want to create a unit test for the User model, but then I encountered a design issue: In order for the User model to use a mocked Facebook SDK, I have to inject this mocked Facebook SDK to the User object (probably using a setter). Therefore I can't construct the Facebook SDK inside the User object. I have to construct it outside the User object, and inject the SDK into the User object. The real client of my User model is the application's controller. Therefore I have to construct the Facebook SDK inside the controller and inject it to the user object. Well, this is a problem because I want my controller to be as clean as possible. I want my controller to be ignorant about the application's data source. I'm not good at explaining something systematically, so you'll probably sleeping before reading this last paragraph. But anyway, I want to ask if anyone here ever encountered the same problem as mine? How do you solve this problem? Regards, Andree

  • How do I wait for a C# event to be raised?

    - by Evan Barkley
    I have a Sender class that sends a Message on a IChannel: public class MessageEventArgs : EventArgs { public Message Message { get; private set; } public MessageEventArgs(Message m) { Message = m; } } public interface IChannel { public event EventHandler<MessageEventArgs> MessageReceived; void Send(Message m); } public class Sender { public const int MaxWaitInMs = 5000; private IChannel _c = ...; public Message Send(Message m) { _c.Send(m); // wait for MaxWaitInMs to get an event from _c.MessageReceived // return the message or null if no message was received in response } } When we send messages, the IChannel sometimes gives a response depending on what kind of Message was sent by raising the MessageReceived event. The event arguments contain the message of interest. I want Sender.Send() method to wait for a short time to see if this event is raised. If so, I'll return its MessageEventArgs.Message property. If not, I return a null Message. How can I wait in this way? I'd prefer not to have do the threading legwork with ManualResetEvents and such, so sticking to regular events would be optimal for me.

  • jquery animated buttons that just wont behave

    - by TJ Sherrill
    Ok I have a inline list of buttons. <ul id="nav"> <li class="home"><a href="#">Menu Item</a></li> <li class="contact"><a href="#">Menu Item</a></li> <li class="about"><a href="#">Menu Item</a></li> </ul> .home{ position:absolute; bottom:0; background-image:url(../img/menu/single_line.png); background-repeat:no-repeat; height:34px; width:134px; } .home_hover{ position:absolute; bottom:0; background-image:url(../img/menu/single_line_over.png); background-repeat:no-repeat; height:70px; width:134px; } $(document).ready(function(){ $("#nav .home").mouseover(function(){ $(this).toggleClass("home_hover").slideToggle("slow"); return false; }).mouseout(function(){ $(this).toggleClass("home_hover").slideToggle("slow"); return false; }); }); Each menu item has a background image, and then when its hovered the background image is replaced by a taller image. Ultimately I am trying to build a simple menu where on mouseover the menu item appears to slide up. But in reality Jquery can animate the toggleClass with slideToggle. The problem is that this current code doesn't behave right. It jumps up and down, because the text is moving. I am pretty new to Jquery so any help is greatly appreciated. I also loaded this up at http://gasworks.ravennainteractive.com/result/ thanks

  • Can CSS change the apparent sequence of elements, e.g. using float or position?

    - by ChrisW
    Edit: answer to this question is easy, a simple example of float left and float right. I'd like to float some annotations to the left of a topic using HTML and CSS, for example the 'status' and 'author' annotations shown in the following mockup/image: For semantic reasons, perhaps: I prefer to use CSS instead of a table-based layout In the HTML, the status should appear after the corresponding heading For example: <h1>This is a section title</h1> <div class="status">approved</div> <div class="author">chris</div> <p>This is some text. Lorem ipsum.</p> <p>Lorem ipsum.</p> <h1>Different section title</h1> <div class="status">rejected</div> <p>Lorem ipsum.</p> I'd like the annotations to be after the heading in the HTML, because everything associated with (i.e. the contents of) a topic is usually whatever is after the topic's heading. However I'd like the annotations to be displayed before (to the left of) the heading, as illustrated above. Is this possible? What is the most semantic HTML, and corresponding CSS, that will render as shown above? Would you recommend a table-based layout instead? Even if that means putting the headings in a table cell? It may not be possible; this answer suggests it isn't possible ... but I don't know CSS well enough to say that for sure.

  • Chrome renders button links completely screwed up when placed inside a paragraph

    - by Ferdy
    I am fairly proficient in CSS but now I am running into a very strange rendering issue in Google Chrome 9. I am trying to create some fancy looking link buttons (basically heavily styled anchors). Here is some example markup: <a href="" class="button"> <figure class="sprite icon icon_back"></figure> Link button with icon</a> This markup may look a litte strange to you, there's a few things you should know: I am using HTML5's figure class to include an icon as part of the button. I have the proper reset CSS applied and Chrome can render this tag for sure. Instead of actually pointing to an image I am applying CSS classes to the figure element. Within the CSS I am using the spriting technique to show the correct portion of a single large sprite image. All of this is working fine in Firefox, and actually also in Chrome. The correct rendering can be seen in the following image: It renders like that in both Firefox and Chrome. Here comes the problem, if I place such a button within paragraph tags <p></p> this is what happens in Chrome only: Notice how the button is ripped apart? Only in Chrome and only when placed inside a paragraph. It gets even stranger: this only happens for the first button inside the paragraph, if I would place three buttons inside a paragraph, only the 1st one is screwed up. Your first question would probably be about the CSS. It is rather verbose so hereby a temporary link to the page in question: Edit: link to live page removed, was only temporary for problem inspection.

  • Ruby-on-Rails: Multiple has_many :through possible?

    - by williamjones
    Is it possible to have multiple has_many :through relationships that pass through each other in Rails? I received the suggestion to do so as a solution for another question I posted, but have been unable to get it to work. Friends are a cyclic association through a join table. The goal is to create a has_many :through for friends_comments, so I can take a User and do something like user.friends_comments to get all comments made by his friends in a single query. class User has_many :friendships has_many :friends, :through => :friendships, :conditions => "status = #{Friendship::FULL}" has_many :comments has_many :friends_comments, :through => :friends, :source => :comments end class Friendship < ActiveRecord::Base belongs_to :user belongs_to :friend, :class_name => "User", :foreign_key => "friend_id" end This looks great, and makes sense, but isn't working for me. This is the error I'm getting in relevant part when I try to access a user's friends_comments: ERROR: column users.user_id does not exist : SELECT "comments".* FROM "comments" INNER JOIN "users" ON "comments".user_id = "users".id WHERE (("users".user_id = 1) AND ((status = 2))) When I just enter user.friends, which works, this is the query it executes: : SELECT "users".* FROM "users" INNER JOIN "friendships" ON "users".id = "friendships".friend_id WHERE (("friendships".user_id = 1) AND ((status = 2))) So it seems like it's entirely forgetting about the original has_many through friendship relationship, and then is inappropriately trying to use the User class as a join table. Am I doing something wrong, or is this simply not possible?

  • Actionscript Enterframe Movement

    - by David
    I am trying to make accelerated movement, but I am running into a problem that, for the life of me, I cannot understand. My class definition: public class Player extends MovieClip { private var stageRef:Stage; private var key:KeyObject; private var acceleration:int = .5; private var curSpeed:int = 0; public function Player(stageRef:Stage) { this.stageRef = stageRef; addEventListener(Event.ENTER_FRAME, enterFrame); key = new KeyObject(stageRef); } public function enterFrame(e:Event) : void { if(key.isDown(key.RIGHT)) { x += 5; } } } This works to move my position in the x direction at a constant rate. However, if I change enterFrame to public function enterFrame(e:Event) : void { if(key.isDown(key.RIGHT)) { x += acceleration; } } No movement occurs. Is there something going on in the event I do not understand? Why is it that I can have x increased by a constant value but not a constant value as defined in a variable in the class? Is it a scope issue?

  • I want tell the VC++ Compiler to compile all code. Can it be done?

    - by KGB
    I am using VS2005 VC++ for unmanaged C++. I have VSTS and am trying to use the code coverage tool to accomplish two things with regards to unit tests: See how much of my referenced code under test is getting executed See how many methods of my code under test (if any) are not unit tested at all Setting up the VSTS code coverage tool (see the link text) and accomplishing task #1 was straightforward. However #2 has been a surprising challenge for me. Here is my test code. class CodeCoverageTarget { public: std::string ThisMethodRuns() { return "Running"; } std::string ThisMethodDoesNotRun() { return "Not Running"; } }; #include <iostream> #include "CodeCoverageTarget.h" using namespace std; int main() { CodeCoverageTarget cct; cout<<cct.ThisMethodRuns()<<endl; } When both methods are defined within the class as above the compiler automatically eliminates the ThisMethodDoesNotRun() from the obj file. If I move it's definition outside the class then it is included in the obj file and the code coverage tool shows it has not been exercised at all. Under most circumstances I want the compiler to do this elimination for me but for the code coverage tool it defeats a significant portion of the value (e.g. finding untested methods). I have tried a number of things to tell the compiler to stop being smart for me and compile everything but I am stumped. It would be nice if the code coverage tool compensated for this (I suppose by scanning the source and matching it up with the linker output) but I didn't find anything to suggest it has a special mode to be turned on. Am I totally missing something simple here or is this not possible with the VC++ compiler + VSTS code coverage tool? Thanks in advance, KGB

  • Java-Hibernate: How can I translate these tables to hibernate annotations?

    - by penas
    I need to create a simple application using these tables: http://stackoverflow.com/questions/2612848/are-these-tables-respect-the-3nf-database-normalization I have created the application using simple old JDBC, but I would like to see how the application would look like using Hibernate, but I don't know how to put the sql code in java. I have found LOTS of examples, but I'm pretty much confused about using Hibernate and I don't know If I made such a good joob. For example, for the first three tables: AUTHOR table * Author_ID, PK * First_Name * Last_Name TITLES table * TITLE_ID, PK * NAME * Author_ID, FK DOMAIN table * DOMAIN_ID, PK * NAME * TITLE_ID, FK The code in java: Table 1 @Entity @Table(name = "AUTHORS", schema = "LIBRARY") public class Author{ @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "Author_ID") private int authorId; @Column(name = "First_Name", nullable = false, length = 50) private String firstName; @Column(name = "Last_Name", nullable = false, length = 40) private String lastName; @OneToMany @JoinColumn(name = "Title_ID") private List<Title> titles; Table 2 @Entity @Table(name = "TITLES") public class Title{ @Id @Column(name = "Title_ID") private int titleID; @Column(name = "Name", nullable = false, length = 50) private String name; @ManyToOne @JoinColumn(name = "Domain_ID") private Domain domains; Table 3 @Entity @Table(name = "DOMAINS") public class Domain{ @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "Domain_ID") private int Domain_ID; @Column(name = "Name", nullable = false, length = 50) private String name; @OneToOne(mappedBy = "domains") private Title title; } Any good? :)

  • 2 iframes with the same display even if the src are different

    - by JulienH
    Hi, I am using this code: <div class="infobox-pair"> <div class="ibp-left"> <iframe width="105" height="350" frameborder="0" scrolling="no" style="width: 311px; height: 105px;" marginwidth="0" marginheight="0" name="infobox_flight" id="ibp-left-iframe" src="http://mywebpage.com/paris"></iframe> </div> <div class="ibp-right"> <iframe width="105" height="350" frameborder="0" scrolling="no" style="width: 311px; height: 105px;" marginwidth="0" marginheight="0" name="infobox_package" id="ibp-right-iframe" src="http://mywebpage.com/lisbonne"></iframe> </div> That is displaying into the same div two different iframes. When I display the page whatever the browser it happens that I can get the same content for both the iframes even if looking at the source code the iframe are still different (based on their src and id). It doesn't happen 100% of the time, I have to refresh sometimes several times to see it. Do you have any clue ? Thanks in advance
