• Commitment to Zend Framework - any arguments against?

  - by Pekka

  I am refurbishing a big CMS that I have been working on for quite a number of years now. The product itself is great, but some components, the Database and translation classes for example, need urgent replacing - partly self-made as far back as 2002, grown into a bit of a chaos over time, and might have trouble surviving a security audit. So, I've been looking closely at a number of frameworks (or, more exactly, component Libraries, as I do not intend to change the basic structure of the CMS) and ended up with liking Zend Framework the best. They offer a solid MVC model but don't force you into it, and they offer a lot of professional components that have obviously received a lot of attention (Did you know there are multiple plurals in Russian, and you can't translate them using a simple ($number == 0) or ($number > 1) switch? I didn't, but Zend_Translate can handle it. Just to illustrate the level of thorougness the library seems to have been built with.) I am now literally at the point of no return, starting to replace key components of the system by the Zend-made ones. I'm not really having second thoughts - and I am surely not looking to incite a flame war - but before going onward, I would like to step back for a moment and look whether there is anything speaking against tying a big system closely to Zend Framework. What I like about Zend: As far as I can see, very high quality code Extremely well documented, at least regarding introductions to how things work (Haven't had to use detailed API documentation yet) Backed by a company that has an interest in seeing the framework prosper Well received in the community, has a considerable user base Employs coding standards I like Comes with a full set of unit tests Feels to me like the right choice to make - or at least, one of the right choices - in terms of modern, professional PHP development. I have been thinking about encapsulating and abstracting ZF's functionality into own classes to be able to switch frameworks more easily, but have come to the conclusion that this would not be a good idea because: it would be an unnecessary level of abstraction it could cost performance the big advantage of using a framework - the existence of a developer base that is familiar with its components - would partly be cancelled out therefore, the commitment to ZF would be a deep one. Thus my question: Is there anything substantial speaking against committing to the Zend Framework? Do you have insider knowledge of plans of Zend Inc.'s to go evil in 2011, and make it a closed source library? Is Zend Inc. run by vampires? Are there conceptual flaws in the code base you start to notice when you've transitioned all your projects to it? Is the appearance of quality code an illusion? Does the code look good, but run terribly slow on anything below my quad-core workstation?

• Using MicrosoftReportViewer with Web Forms programmatically

  - by user283897

  Hi, I'm repeating my question because the prior one under this topic was lost. Could you please help me? I want to use MicrosoftReportViewer for Web Forms so that the DataSource be set programmatically. There is some sample code on the Internet for Windows Forms but I haven't found anything for Web Forms. For example, here is some code I've tried to use. It gives no errors but nothing is displayed. How should I modify the code to display a table in the ReportViewer? Imports System.Data Imports Microsoft.Reporting.WebForms Partial Class TestReportViewer Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load CreateReport() End Sub Sub CreateReport() Dim dt As DataTable Dim rpt As ReportDataSource dt = New DataTable("Sample") With dt .Columns.Add("No", GetType(Integer)) .Columns.Add("Name") .Rows.Add(1, "A1") .Rows.Add(2, "A2") .Rows.Add(3, "A3") .Rows.Add(4, "A4") .AcceptChanges() End With rpt = New ReportDataSource rpt.DataMember = "Sample" rpt.Value = dt rpt.Name = "test" With ReportViewer1 .LocalReport.DataSources.Add(rpt) .DataBind() .LocalReport.Refresh() End With End Sub End Class

• Eclipse: find resource on classpath

  - by seanizer

  Is there a way in eclipse to search the classpath for arbitrary resource file names (or patterns)? I know I can use either Navigate > Open Type (which will scan the classpath for classes) or Navigate > Open Resource, which will search for any resource type, but only in my project folders. Is there any way to achieve a combination ob both, to do a resource search (something like *.xsd) that searches all jars on the classpath?

• is there a native php function to see if one array of values is in another array?

  - by Haroldo

  Is there a better method than loop with strpos()? Not i'm looking for partial matches and not an in_array() type method. example needle and haystack and desired return: $needles[0] = 'naan bread'; $needles[1] = 'cheesestrings'; $needles[2] = 'risotto'; $needles[3] = 'cake'; $haystack[0] = 'bread'; $haystack[1] = 'wine'; $haystack[2] = 'soup'; $haystack[3] = 'cheese'; //desired output - but what's the best method of getting this array? $matches[0] = 'bread'; $matches[1] = 'cheese';

• ruby on rails has_many through relationship

  - by BennyB

  Hi i'm having a little trouble with a has_many through relationship for my app and was hoping to find some help. So i've got Users & Lectures. Lectures are created by one user but then other users can then "join" the Lectures that have been created. Users have their own profile feed of the Lectures they have created & also have a feed of Lectures friends have created. This question however is not about creating a lecture but rather "Joining" a lecture that has been created already. I've created a "lecturerelationships" model & controller to handle this relationship between Lectures & the Users who have Joined (which i call "actives"). Users also then MUST "Exit" the Lecture (either by clicking "Exit" or navigating to one of the header navigation links). I'm grateful if anyone can work through some of this with me... I've got: Users.rb model Lectures.rb model Users_controller Lectures_controller then the following model lecturerelationship.rb class lecturerelationship < ActiveRecord::Base attr_accessible :active_id, :joinedlecture_id belongs_to :active, :class_name => "User" belongs_to :joinedlecture, :class_name => "Lecture" validates :active_id, :presence => true validates :joinedlecture_id, :presence => true end lecturerelationships_controller.rb class LecturerelationshipsController < ApplicationController before_filter :signed_in_user def create @lecture = Lecture.find(params[:lecturerelationship][:joinedlecture_id]) current_user.join!(@lecture) redirect_to @lecture end def destroy @lecture = Lecturerelationship.find(params[:id]).joinedlecture current_user.exit!(@user) redirect_to @user end end Lectures that have been created (by friends) show up on a users feed in the following file _activity_item.html.erb <li id="<%= activity_item.id %>"> <%= link_to gravatar_for(activity_item.user, :size => 200), activity_item.user %><br clear="all"> <%= render :partial => 'shared/join', :locals => {:activity_item => activity_item} %> <span class="title"><%= link_to activity_item.title, lecture_url(activity_item) %></span><br clear="all"> <span class="user"> Joined by <%= link_to activity_item.user.name, activity_item.user %> </span><br clear="all"> <span class="timestamp"> <%= time_ago_in_words(activity_item.created_at) %> ago. </span> <% if current_user?(activity_item.user) %> <%= link_to "delete", activity_item, :method => :delete, :confirm => "Are you sure?", :title => activity_item.content %> <% end %> </li> Then you see I link to the the 'shared/join' partial above which can be seen in the file below _join.html.erb <%= form_for(current_user.lecturerelationships.build(:joinedlecture_id => activity_item.id)) do |f| %> <div> <%= f.hidden_field :joinedlecture_id %> </div> <%= f.submit "Join", :class => "btn btn-large btn-info" %> <% end %> Some more files that might be needed: config/routes.rb SampleApp::Application.routes.draw do resources :users do member do get :following, :followers, :joined_lectures end end resources :sessions, :only => [:new, :create, :destroy] resources :lectures, :only => [:create, :destroy, :show] resources :relationships, :only => [:create, :destroy] #for users following each other resources :lecturerelationships, :only => [:create, :destroy] #users joining existing lectures So what happens is the lecture comes in my activity_feed with a Join button option at the bottom...which should create a lecturerelationship of an "active" & "joinedlecture" (which obviously are supposed to be coming from the user & lecture classes. But the error i get when i click the join button is as follows: ActiveRecord::StatementInvalid in LecturerelationshipsController#create SQLite3::ConstraintException: constraint failed: INSERT INTO "lecturerelationships" ("active_id", "created_at", "joinedlecture_id", "updated_at") VALUES (?, ?, ?, ?) Also i've included my user model (seems the error is referring to it) user.rb class User < ActiveRecord::Base attr_accessible :email, :name, :password, :password_confirmation has_secure_password has_many :lectures, :dependent => :destroy has_many :lecturerelationships, :foreign_key => "active_id", :dependent => :destroy has_many :joined_lectures, :through => :lecturerelationships, :source => :joinedlecture before_save { |user| user.email = email.downcase } before_save :create_remember_token validates :name, :presence => true, :length => { :maximum => 50 } VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i validates :email, :presence => true, :format => { :with => VALID_EMAIL_REGEX }, :uniqueness => { :case_sensitive => false } validates :password, :presence => true, :length => { :minimum => 6 } validates :password_confirmation, :presence => true def activity # This feed is for "My Activity" - basically lectures i've started Lecture.where("user_id = ?", id) end def friendactivity Lecture.from_users_followed_by(self) end # lECTURE TO USER (JOINING) RELATIONSHIPS def joined?(selected_lecture) lecturerelationships.find_by_joinedlecture_id(selected_lecture.id) end def join!(selected_lecture) lecturerelationships.create!(:joinedlecture_id => selected_lecture.id) end def exit!(selected_lecture) lecturerelationships.find_by_joinedlecture_id(selected_lecture.id).destroy end end Thanks for any and all help - i'll be on here for a while so as mentioned i'd GREATLY appreciate someone who may have the time to work through my issues with me...

• When I change templates in Netbeans, why doesn't anything happen?

  - by Matthew

  I want to modify the "Java class" template, so that the class javadoc comment includes more than just the author. In Netbeans 6.8., I go to Tools Templates Java Java Class, and modify the template. However, nothing seems to change. I tried restarting Netbeans, just in case, but the old template is still used. How do I get Netbeans to recognize changes to the template for Java Classes?

• Is it possible to split a form into multiple erb modules?

  - by Ya.

  I have a large form with multiple tabs and would like to be able to split it into multiple modules and include each as a partial. Something like: main.html.erb: <%= form_for (@myobject) do |f| %> <%= render "module1" %> .... module1.html.erb: <%= f.text_field :field1 %> ... Needless to say, when I do it like this I get an error from module1 that "f" is undefined. Is there a way to split form fields into multiple modules?

• What methods are available in the WinAPI for accessing programs in the system tray?

  - by Corey Ogburn

  What DLLs would have functions for accessing things in the System Tray? Do I even need the winapi, or are there classes already available in the Class Library for this? I'm hoping to find a way to emulate all the functionality of the system tray, i.e. the icons, the mouseover text, and the capability to display the context menu.

• User control attributes at design-time

  I'm testing a simple User Control in Visual Studio 2008: A Panel named Wrapper with some controls inside. Can Visual Studio handle this at design time? public partial class TestControl : System.Web.UI.UserControl { [Description("Css class of the div around the control.")] [CssClassProperty] public string CssClass { get { return Wrapper.CssClass; } set { Wrapper.CssClass = value; } } } When setting the CssClass property, it doesn't update the css of the Panel at design time. Am I hoping for too much?

• Deep Copy using Reflection in an Extension Method for Silverlight?

  - by didibus

  So I'm trying to find a generic extension method that creates a deep copy of an object using reflection, that would work in Silverlight. Deep copy using serialization is not so great in Silverlight, since it runs in partial trust and the BinaryFormatter does not exist. I also know that reflection would be faster then serialization for cloning. It would be nice to have a method that works to copy public, private and protected fields, and is recursive so that it can copy objects in objects, and that would also be able to handle collections, arrays, etc. I have searched online, and can only find shallow copy implementations using reflection. I don't understand why, since you can just use MemberwiseClone, so to me, those implementations are useless. Thank You.

• Generate A Simple Read-Only DAL?

  - by David

  I've been looking around for a simple solution to this, trying my best to lean towards something like NHibernate, but so far everything I've found seems to be trying to solve a slightly different problem. Here's what I'm looking at in my current project: We have an IBM iSeries database as a primary repository for a third party software suite used for our core business (a financial institution). Part of what my team does is write applications that report on or key off of a lot of this data in some way. In the past, we've been manually creating ADO .NET connections (we're using .NET 3.5 and Visual Studio 2008, by the way) and manually writing queries, etc. Moving forward, I'd like to simplify the process of getting data from there for the development team. Rather than creating connections and queries and all that each time, I'd much rather a developer be able to simply do something like this: var something = (from t in TableName select t); And, ideally, they'd just get some IQueryable or IEnumerable of generated entities. This would be done inside a new domain core that I'm building where these entities would live and the applications would interface with it through a request/response service layer. A few things to note are: The entities that correspond to the database tables should be generated once and we'd prefer to manually keep them updated over time. That is, if columns/tables are added to the database then we shouldn't have to do anything. (If some are deleted, of course, it will break, but that's fine.) But if we need to use a new column, we should be able to just add it to the necessary class(es) without having to re-gen the whole thing. The whole thing should be SELECT-only. We're not doing a full DAL here because we don't want to be able to break anything in the database (even accidentally). We don't need any kind of mapping between our domain objects and the generated entity types. The domain barely covers a fraction of the data that's in there, most of it we'll never need, and we would rather just create re-usable maps manually over time. I already have a logical separation for the DAL where my "repository" classes return domain objects, I'm just looking for a better alternative to manual ADO to be used inside the repository classes. Any suggestions? It seems like what I'm doing is just enough outside the normal demand for DAL/ORM tools/tutorials online that I haven't been able to find anything. Or maybe I'm just overlooking something obvious?

• Good ways to map a 2D side shooter (somewhat like liero, or soldat)

  - by Blaze

  I'm wondering what way would be best to render a 2D map for a shooter (these will be static maps) similar to Soldat. Multiple options I've considered are a tile based map (stored in txt files), or just creating different classes for the different terrains I plan to use and creating a data structure to read/store them in a file. (I want to also be able to include things like jumping/running on walls, sliding down walls/slopes ect) I feel like there must be a better way than either of these, but haven't been able to find definitive information :/ Thanks :)

• Returning a static array without using a class field

  - by Bart Friederichs

  I have the following base and derived (partial, for sake of brevity) classes: class Base { public abstract int[] someArray { get; } } class Derived : Base { private readonly static int[] _someArray = new int[] { 1,2,3,4 }; public override int[] someArray { get { return _someArray; } } } What I would like now, is put the new int[] { 1,2,3,4 } in the return part of the getter. But, that would create a new array every time the getter is called. Is it possible to directly return some kind of object, which stays the same for all objects of class Derived ? Something along the lines of (I know this is invalid C#): get { return (int[]) { 1, 2, 3, 4 }; }

• Are there localization tools which spot content strings in xaml/wpf?

  - by Noel Kennedy

  When globalizing a wpf application with static resx classes, it's very easy to miss the odd label or button that has its Content property set to a hard coded string in a particular language, ie English. These should of course be moved off to a {x:Static ...} so they can be localised for each culture. Are there any tools which can spot this and warn you? Built in to VS would be ideal, but I'm thinking that 'style cop' type build tools would do the job as well.

• IoC.Resolve vs Constructor Injection

  - by Omu

  I heard a lot of people saying that it is a bad practice to use IoC.Resolve(), but I never heard a good reason why (if it's all about testing than you can just mock the container, and you're done). now the advantages of using Resolve instead of Constructor Injection is that you don't need to create classes that have 5 parameters in the constructor, and whenever you are going to create a instance of that class you're not gonna need to provide it with anything
