  • ASP.NET MVC IoC usability

    - by Andrew Florko
    Hello everybody, How often do you use IoC for controllers/DAL in real projects? IoC allows to abstract application from concrete implementation with additional layer of interfaces that should be implemented. But how often concrete implementation changes? Should we really have to do job twice adding method to interface then the implementation if implementation hardly will ever be changed? I took part in about 10 asp.net projects and DAL (ORM-like and not) was never rewritten completely. Watching lots of videos I clearly understand that IoC "is cool" and the really nice way to program, but does it really needed?

  • Drupal: Content in blocks from node_reference fields?

    - by Marco
    After only a few weeks of working with Drupal I've come up with a recurring problem, which I don't really have an optimal solution to, so I'm hoping that someone here might be able to give some best practice pointers. What I have is a region inside my node.tpl.php, which is populated with blocks that display content from two different CCK fields of the type node_reference. This works fine when displaying a single node. The problem appears when I need to use a view. For example, lets say I have a news listing, and a single news item view. When I display the single news item I can use the news node node_reference field to reference whatever material I would like to have in my sidebar, but when on the news listing view I would like to reference nodes separately. What would be the best practice to solve this? I'm having a few ideas, but none seem like the logical choice, how would you do?

  • Where UnityContainerElement in Unity 2?

    - by TheAbdalla
    I was in Unity 1.2, use the following code: UnityConfigurationSection UnitySection = (UnityConfigurationSection)ConfigurationManager.GetSection("Unity"); Dictionary<string, IUnityContainer> Containers = new Dictionary<string, IUnityContainer>(); foreach (UnityContainerElement element in UnitySection.Containers) { IUnityContainer container = new UnityContainer(); Containers.Add(element.Name, container); element.Configure(Containers[element.Name]); } but, I couldn't do so in the Unity 2.0 beta2, because The class 'UnityContainerElement' does not exist in Unity 2 beta2. How can I do this in the new version?

  • Best practice - When to evaluate conditionals of function execution

    - by Tesserex
    If I have a function called from a few places, and it requires some condition to be met for anything it does to execute, where should that condition be checked? In my case, it's for drawing - if the mouse button is held down, then execute the drawing logic (this is being done in the mouse movement handler for when you drag.) Option one says put it in the function so that it's guaranteed to be checked. Abstracted, if you will. public function Foo() { DoThing(); } private function DoThing() { if (!condition) return; // do stuff } The problem I have with this is that when reading the code of Foo, which may be far away from DoThing, it looks like a bug. The first thought is that the condition isn't being checked. Option two, then, is to check before calling. public function Foo() { if (condition) DoThing(); } This reads better, but now you have to worry about checking from everywhere you call it. Option three is to rename the function to be more descriptive. public function Foo() { DoThingOnlyIfCondition(); } private function DoThingOnlyIfCondition() { if (!condition) return; // do stuff } Is this the "correct" solution? Or is this going a bit too far? I feel like if everything were like this function names would start to duplicate their code. About this being subjective: of course it is, and there may not be a right answer, but I think it's still perfectly at home here. Getting advice from better programmers than I is the second best way to learn. Subjective questions are exactly the kind of thing Google can't answer.

  • ASP.NET MVC null ViewResult

    - by David Neale
    How should one deal with an MVC controller returning a null ViewResult? As an example I am creating a simple edit view: public ActionResult Edit(int id) { var person = (from p in context.SWLiftShare_Persons where p.id == id select p).SingleOrDefault(); if (person != null) { return View(person); } else return View(); } I guess in reality there's no point in checking for a null result in the controller because the view picks out properties from the model: <h2>Edit - <%= Html.Encode(Model.Name) %></h2> <%= Html.ValidationSummary("Edit was unsuccessful. Please correct the errors and try again.") %> <% using (Html.BeginForm()) {%> <fieldset> <legend>Fields</legend> <p> <label for="id">id: <%= Html.Encode(Model.id) %></label> </p> <p> <label for="CollarNumber">CollarNumber:</label> <%= Html.TextBox("CollarNumber", Model.CollarNumber)%> <%= Html.ValidationMessage("CollarNumber", "*") %> </p> <p> <label for="Name">Name:</label> <%= Html.TextBox("Name", Model.Name)%> <%= Html.ValidationMessage("Name", "*") %> </p> <p> <label for="EmailAddress">EmailAddress:</label> <%= Html.TextBox("EmailAddress", Model.EmailAddress, new { style = "width:300px" })%> <%= Html.ValidationMessage("EmailAddress", "*") %> </p> <p> <input type="submit" value="Save" /> </p> </fieldset> <% } %> I could just wrap everything in a <% if(Model != null) { //render edit markup... etc. but that seems rather unelegant. Is there a better way to deal with this?

  • Format for storing contacts in a database

    - by Gart
    I'm thinking of the best way to store personal contacts in a database for a business application. The traditional and straightforward approach would be to create a table with columns for each element, i.e. Name, Telephone Number, Job title, Address, etc... However, there are known industry standards for this kind of data, like for example vCard, or hCard, or vCard-RDF/XML or even Windows Contacts XML Schema. Utilizing an standard format would offer some benefits, like inter-operablilty with other systems. But how can I decide which method to use? The requirements are mainly to store the data. Search and ordering queries are highly unlikely but possible. The volume of the data is 100,000 records at maximum. My database engine supports native XML columns. I have been thinking to use some XML-based format to store the personal contacts. Then it will be possible to utilize XML indexes on this data, if searching and ordering is needed. Is this a good approach? Which contacts format and schema would you recommend for this?

  • are there any negative implications of sourcing a javascript file that does not actually exist?

    - by dreftymac
    If you do script src="/path/to/nonexistent/file.js" in an HTML file and call that in a browser, and there are no dependencies or resources anywhere else in the HTML file that expect the file or code therein to actually exist, is there anything inherently bad-practice about doing this? Yes, it is an odd question. The rationale is the developer is dealing with a CMS that allows custom (self-contained) javascript files to be provided in certain circumstances. The problem is the CMS is not very flexible when it comes to creating conditional includes for javascript. Therefore it is easier to just make references to the self-contained js files regardless of whether they are actually at the specified path. Since no errors are displayed to the user, should this practice be considered a viable option?

  • How to build a JSON response by combining @foo.to_json(options) and @bars.to_json(options) in Rails

    - by smotchkkiss
    First, the desired result I have User and Item models. I'd like to build a JSON response that looks like this: { "user": {"username":"Bob!","foo":"whatever","bar":"hello!"}, "items": [ {"id":1, "name":"one", "zim":"planet", "gir":"earth"}, {"id":2, "name":"two", "zim":"planet", "gir":"mars"} ] } However, my User and Item model have more attributes than just those. I found a way to get this to work, but beware, it's not pretty... Please help... My hacks home_controller.rb class HomeController < ApplicationController def observe respond_to do |format| format.js { render :json => Observation.new(current_user, @items).to_json } end end end observation.rb # NOTE: this is not a subclass of ActiveRecord::Base # this class just serves as a container to aggregate all "observable" objects class Observation attr_accessor :user, :items def initialize(user, items) self.user = user self.items = items end # The JSON needs to be decoded before it's sent to the `to_json` method in the home_controller otherwise the JSON will be escaped... # What a mess! def to_json { :user => ActiveSupport::JSON.decode(user.to_json(:only => :username, :methods => [:foo, :bar])), :items => ActiveSupport::JSON.decode(auctions.to_json(:only => [:id, :name], :methods => [:zim, :gir])) } end end

  • Optimal UI For Single Zip Code Entry on iPhone

    - by sylvanaar
    I need to prompt the user to enter his/her zip code at certain times in my iPhone application. I cannot store it or get it from the user's current location. What is the optimal input method? I started with a 5 wheel picker. This seemed like a bad direction, so I opted for a PIN-like entry screen. My implepentation is about the same as the 'enter passcode' screen you see when unlocking the iphone - including automatically ending input on the 5th digit instead of providing a return/enter button. Does this seem optimal? Or is there a better way? Note: I only need to accept a 5 digit US zip code.

  • Is there a way to generate a short random id, avoiding collisions, without hitting persistent storag

    - by bshacklett
    If you've used GoToMeeting, that's the type of ID I want. I'd like it to be random so that it obfuscates the number of items being tracked and short, so that it's easy to reference manually; UUIDs are way too long. I'd like to avoid hitting persistent storage merely for performance reasons, but I can't think of any other way to avoid collisions. Is 9 digits enough to do something time-based?

  • Binning a numeric variable in R

    - by McPeterson
    I have a vector X that contains positive numbers that I want to bin/discretize. For this vector, I want the numbers [0, 10) to show up just as they exist in the vector, but numbers [10,∞) to be 10+. I'm using: x <- c(0,1,3,4,2,4,2,5,43,432,34,2,34,2,342,3,4,2) binned.x <- as.factor(ifelse(x > 10,"10+",x)) but this feels klugey to me. Does anyone know a better solution or a different approach? mcpeterson

  • Best Practice Guide: Swing

    - by wishi_
    Hi! Does anybody know Swing related GUI guidelines - specifically on how to design Swing apps and which components I should use? I'm not looking for an official standard, but pragmatic tips I can use to set a good standard for my projects. I haven't used too much of Swing by myself. Surely clicking a GUI with a GUI designer isn't a big deal. However I'd like to get some insights from people who have experience with Swing and know what to avoid. Swing lately (in Java 6- 10) got decent changes. So there isn't too much specific standardization out there currently.

  • Naming convention for utility classes in Java

    - by Zarjay
    When writing utility classes in Java, what are some good guidelines to follow? Should packges be "util" or "utils"? Is it ClassUtil or ClassUtils? When is a class a "Helper" or a "Utility"? Utility or Utilities? Or do you use a mixture of them? The standard Java library uses both Utils and Utilities: javax.swing.Utilities javax.print.attribute.AttributeSetUtilities javax.swing.plaf.basic.BasicGraphicsUtils Apache uses a variety of Util and Utils, although mostly Utils: org.apache.commons.modeler.util.DomUtil org.apache.commons.modeler.util.IntrospectionUtils org.apache.commons.io.FileSystemUtils org.apache.lucene.wordnet.AnalyzerUtil org.apache.lucene.util.ArrayUtil org.apache.lucene.xmlparser.DOMUtils Spring uses a lot of Helper and Utils classes: org.springframework.web.util.UrlPathHelper org.springframework.core.ReflectiveVisitorHelper org.springframework.core.NestedExceptionUtils org.springframework.util.NumberUtils So, how do you name your utility classes?

  • Multi-level shop, xml or sql. best practice?

    - by danrichardson
    Hello, i have a general "best practice" question regarding building a multi-level shop, which i hope doesn't get marked down/deleted as i personally think it's quite a good "subjective" question. I am a developer in charge (in most part) of maintaining and evolving a cms system and associated front-end functionality. Over the past half year i have developed a multiple level shop system so that an infinite level of categories may exist down into a product level and all works fine. However over the last week or so i have questioned by own methods in front-end development and the best way to show the multi-level data structure. I currently use a sql server database (2000) and pull out all the shop levels and then process them into an enumerable typed list with child enumerable typed lists, so that all levels are sorted. This in my head seems quite process heavy, but we're not talking about thousands of rows, generally only 1-500 rows maybe. I have been toying with the idea recently of storing the structure in an XML document (as well as the database) and then sending last modified headers when serving/requesting the document for, which would then be processed as/when nessecary with an xsl(t) document - which would be processed server side. This is quite a handy, reusable method of storing the data but does it have more overheads in the fact im opening and closing files? And also the xml will require a bit of processing to pull out blocks of xml if for instance i wanted to show two level mid way through the tree for a side menu. I use the above method for sitemap purposes so there is currently already code i have built which does what i require, but unsure what the best process is to go about. Maybe a hybrid method which pulls out the data, sorts it and then makes an xml document/stream (XDocument/XmlDocument) for xsl processing is a good way? - This is the way i currently make the cms work for the shop. So really (and thanks for sticking with me on this), i am just wandering which methods other people use or recommend as being the best/most logical way of doing things. Thanks Dan

  • isPostBack as Query Parameter

    - by Steven
    I created an ASPX page with search controls to the left bound as controls for an AccessDataSource. I want the data grid to be blank on the first calling of the page, but show the results for subsequent page loads. I plan to achieve this by putting [pFirstRun] = False as my first WHERE condition with the parameter pFirstRun tied to the value isPostBack. How do I achieve this? Alternatively, is there a better way to achieve this goal?

  • Is it good to use .settings for storing controls text data?

    - by Zenya
    In my WinForms applications I often put the controls text data (form title, labels texts, button captions, etc.) into a .settings (feature automatically generated by Visual Studio - based on the ApplicationSettingsBase class). In particular, Add a form or a control. In Solution Explorer add a new string item into the application scope of the settings file. Bind the control text property with the corresponding item of the settings file (through the property binding). Good point of this is that all my text data is collected in one place and easy to check and edit. Also it is convenient when I want to use the same text for several controls. However, I haven't heard that somebody uses the .settings such way. In tutorials for creating multilingual applications, for example, it is recommended to enter texts directly into the control property. So, is it good practice to use .settings for storing controls text data? Brief conclusion from the answers: Storing controls text data in the .settings is not common practice.

  • Best practice for handling ConnectionDroppedHandler in OCS Server Application

    - by Paul Nearney
    Hi all, In general, it seems that the majority of times that ConnectionDroppedHandler would get called in an OCS server application is for expected reasons e.g. server application has been unregistered, server is shutting down, etc. Are there any unexpected situations in which ConnectionDroppedHandler can be called? Basically, i'm wondering whether it will ever be necessary to log an error to the event log from this event handler. Many thanks, Paul
