• Does MVC replace traditional manually created UI, BLL, DAL ?

  - by used2could

  I'm use to creating the UI, BLL, DAL by hand (some times i've used LINQ-SQL or SubSonic for the DAL). I've done several small projects using MVC since it's release. On these projects i've still continued to write a BLL and DAL by hand and then incorporate those into the MVC's models/controllers. Looking to optimize my time on projects this seems like over kill and a potential waste of time. My question is: Would it be acceptable to roll a DAL such as SubSonic and directly use it in the Models/Controllers of my MVC web app? Now the models & controllers would act as the BLL. I just see this as a major time savor to not have to worry about another tier. (Agree ? "Please state way" : "Make argument")

• .NET Recaptcha https

  - by TygerKrash

  We've started using the ASP.NET recaptcha control and it works fine. but one of the requirements we have is that all outbound traffic goes over Https. I know that recaptcha supports https, but It's not clear how to configure (or even if it is configurable) when using the ASP.NET plugin option. has anyone got any experience of this? I'll expand a little on what I've found so far.... The Recaptcha package contains 3 public classes RecaptchaControl, RecaptchaValidator and RecaptchaResponse RecaptchaControl is an Asp.NET control, the recaptcha specific methods on there seem to be concerning themes/look and feel. An instance of the Validator has a RemoteIP field (which I presume would represent the verification server), but I can't a way of binding that to the control. RecaptchaResponse seems to more or less represent an enum with possible responses (valid/invalid/failed to connect).

• How do I get property injection working in Ninject for a ValidationAttribute in MVC?

  - by jaltiere

  I have a validation attribute set up where I need to hit the database to accomplish the validation. I tried setting up property injection the same way I do elsewhere in the project but it's not working. What step am I missing? public class ApplicationIDValidAttribute : ValidationAttribute { [Inject] protected IRepository<MyType> MyRepo; public override bool IsValid(object value) { if (value == null) return true; int id; if (!Int32.TryParse(value.ToString(), out id)) return false; // MyRepo is null here and is never injected var obj= MyRepo.LoadById(id); return (obj!= null); } One other thing to point out, I have the Ninject kernel set up to inject non-public properties, so I don't think that is the problem. I'm using Ninject 2, MVC 2, and the MVC 2 version of Ninject.Web.MVC. Thanks!

• Java Spring 3.0 MVC Annotation vs COC. Whats the prefered method in the Java community?

  - by Athens

  I am using Spring's MVC framework for an application I'm hosting on Google's App Engine. So far, my controllers are registered via the @Controller annotation; however, prior to getting into Spring, I evaluated ASP.net MVC 2 which requires no configuration and is based on convention. Is convention over configuration (COC) the current and preferred method in the Java community to implement MVC with Spring. Also, this may be a result of my limited knowledge so far but i noticed that i could only instantiate my Controllers the required constuctor injection if i use the COC method via the ControllerClassNameHandlerMapping. For instance the following controller bean config will fail if i use the defaultannotationhandlermapping. My com.domain.TestController controller works fine if i use ControllerClassNameHandlerMapping/COC but it results in an error when i use defaultannotationhandlermapping/Annotations.

• Restrict violation of architecture - asp.net MVP

  - by Srikanth

  If we had a defined hierarchy in an application. For ex a 3 - tier architecture, how do we restrict subsequent developers from violating the norms? For ex, in case of MVP (not asp.net MVC) architecture, the presenter should always bind the model and view. This helps in writing proper unit test programs. However, we had instances where people directly imported the model in view and called the functions violating the norms and hence the test cases couldn't be written properly. Is there a way we can restrict which classes are allowed to inherit from a set of classes? I am looking at various possibilities, including adopting a different design pattern, however a new approach should be worth the code change involved.

• Is MVC now the only way to write PHP?

  - by JasonS

  Hey... its XMAS Eve and something is bugging me... yes, I have work on my mind even when I am on holiday. The vast amount of frameworks available for PHP now use MVC. Even ASP.net has its own MVC module. I can see the attraction of MVC, I really can and I use it frequently. The only downside that I can see is that you have to fire up the whole system to execute a page request. Depending on your task this can be a little wasteful. So the question. In a professional environment is this the only way to use PHP nowadays or are their other design methods which have alternative benefits?

• How can I optimize MVC and IIS pipeline to obtain higher speed?

  - by Andy

  Hi, I am doing performance tweaking of a simple app that uses MVC on IIS 7.5. I have a StopWatch starting up in Application_BeginRequest and I take a snapshot at Controller.OnActionExecuting. So I measure the time spend in the entire IIS pipeline: from request receipt to the moment execution finally gets to my controller. I obtain 700 microseconds on my 3GHz quad-core (project compiled Release x64), and I wonder where the bottleneck is, especially hearing some people say that one can get up to 8000 page loads per second with MVC. How can I optimize MVC and IIS pipeline to obtain higher speed?

• How can I use MVC ideas without using classes?

  - by jpjp

  As of right now, I am still shaky on classes, so I don't want to use any classes for my site. I'm still practicing with classes. But how can I implement the MVC idea without classes? Would this work for a MVC? index.php (the view) index_controller.php index_model.php Is this right for what a MVC should be? View: show html, css, forms Controller: get $_POST from forms and any data from the user, get info from db Model: do all the functions, insert/delete in db, etc Basically separate the HTML/css for the view, all the data collecting for the controller, and the logic for the model. And just connect them all using require_once.

• Upload/Download files with ASP.Net using Visual Studio Web Server

  - by jlnorsworthy

  I need to upload image files and store them on the webserver, then be able to display them in html. I'm currently using AppDomain.CurrentDomain.BaseDirectory to get a path to read and write files. Firefox won't display the image as I just get an img tag with "src='C:...' Is it possible to read/write files like this with Visual Studio web server? I know it'll be possible with IIS, but I don't want to do that if I don't have to (pretty new to web development) I'm implementing this with ASP.Net MVC 2, but I don't think that is relevant.

• LINQ parent child relation

  - by Shane Km

  I'm working on the BLOG functionality in MVC. I need to be able to create 'blog comments'. So each comment may have a parent comment etc. Given table "Comments": CommentId - int - identity autoincrement PostId - int ParentId - int Comment - string Is there a way to get a list of comments for a given article ordered by CreateDate and ParentId? Or maybe there is a better table design you may suggest. What is the best design when inserting Post comments like this? I'm using Entity framework. thanks

• Possible to have empty values with Html For Helpers such as Html.TextBoxFor()?

  - by chobo2

  Hi Is it possible to have to make a html for helper in asp.net mvc 2.0 have a default value of "empty string" Like if I do this Html.TextBoxFor( u => u.ProductName) would render to <input id ="ProductName" name="ProdcutName" type="text" value="Jim" /> Now I don't want the textbox to display jim. I want it to display nothing. <input id ="ProductName" name="ProdcutName" type="text" value="" /> I tried to do this Html.TextBoxFor( u => u.ProductName, new { @value = " "}) but that seems to do nothing. So how can I do this. I hope you can do something like this otherwise I think these new helpers have a great flaw since now I need to use like javascript to remove them since I hardly ever want a default value in the textbox especially when I have a label right beside the textbox saying what it is.

• asp.net global resources problem

  - by Bystrik Jurina

  Hello. I have a weird problem with global resources in my asp.net mvc web application. I have some resources in separate project(not a web app project). Those resources have following settings: Build action: Embedded Resource, Copy To Output Directory: Do not copy, Custom Tool: ResXFileCodeGenerator. When I change an existing value in resource file, build solution in release mode and upload neccesary dll files back to server, the previous values in resources are still shown. However, when I add a new key into resource file, the value of this key is shown properly. I do not have this problem during debugging on localhost. Thanks

• Field annotated multiple times by the same attribute

  - by Jaroslaw Waliszko

  For my ASP.NET MVC application I've created custom validation attribute, and indicated that more than one instance of it can be specified for a single field or property: [AttributeUsage(AttributeTargets.Field | AttributeTargets.Property, AllowMultiple = true)] public sealed class SomeAttribute: ValidationAttribute I've created validator for such an attribute: public class SomeValidator : DataAnnotationsModelValidator<SomeAttribute> and wire up this in the Application_Start of Global.asax DataAnnotationsModelValidatorProvider.RegisterAdapter( typeof (SomeAttribute), typeof (SomeValidator)); Finally, if I use my attribute in the desired way: [SomeAttribute(...)] //first [SomeAttribute(...)] //second public string SomeField { get; set; } when validation is executed by the framework, only first attribute instance is invoked. Second one seems to be dead. I've noticed that during each request only single validator instance is created (for the first annotation). How to solve this problem and fire all attributes?

• ASP.NET MVC vs. Jquery/AJAX (Where to draw the dividing line?)

  - by punkouter

  I am learning MVC and I understand the basics now. It is very good for CRUD pages and has built in HTTP methods to post/get edits/updates. That is nice. This is all very testable by just creating a new controller and testing it. But I was thinking about other web page scenerios when using MVC. What about a page that has 2 listboxes that you add/remove users with. (A button will move the user from one listbox to another) This would be done using Jquery/Javascript... But then what happens to testing? How do you test adding/removing users from a listbox like that example? It seems to me the more jquery you use the less testable the page becomes right? When you get beyond basic forms being filled out then you need to use something more than the standard MVC pages. What is the correct philosophy on this on when am I not understanding ?

• ASP.NET permissions issues

  - by Paul

  Im using Windows Server 2008, IIS7, .NET 4 and when I use the FileUpload control to save a file to a directory I get : Access to the path 'C:\xxx\Websites\CMS\Admin\test' is denied. I have given the test folder full control permissions for NETWORK SERVICE but it makes no difference. I have given full control to the Everyone user but makes no difference. It might have something to do with the fact that up in the CMS folder there is a MVC web application and in the CMS\Admin folder there is a web forms web application. It is the web forms web application that is trying to upload the file and getting the permissions error. Can anyone offer a suggestion.

• How many SQL queries per HTTP request is optimal?

  - by Chris Kooken

  I know the answer to this question for the most part is "It Depends", however I wanted to see if anyone had some pointers. We execute queries each request in ASP.NET MVC. Each request we need to get user rights information, and Various data for the Views that we are displaying. How many is too much, I know I should be conscious to the number of queries i am executing. I would assume if they are small queries and optimized out, half-a-dozen should be okay? Am I right? What do you think?

• Adding an ASP website in IIS7.5 on Windows 7

  - by birdus

  enter preformatted text hereI'm trying to add an ASP website under IIS 7.5 on Windows 7 and am having no luck so far. This site is just for me to hit locally. I need to make some changes to some of the HTML in some of the ASP files and I just need to be able to test my changes as I make them. I installed IIS and checked the box for ASP. Next, I added an Application Pool which I called ASP and which has "No Managed Code" and "ASP" set. Next, I added the website by right-clicking "Sites" then clicking "Add Web Site...". I gave it a name, set it to use the ASP app pool, pointed it to the path where the ASP code is (I left it at pass-through authentication), and typed in 5555 as the port, so as to not interfere with the default website. The code is sitting on my server and the path simply uses the mapped drive that I always use to access files on that drive array. When I type in http://mysite:5555, I get "could not find mysite:5555". I don't really know if all these settings are correct or what else I should try. What am I missing? Thanks, Jay

• URL Routing in ASP.NET 4.0

  In the .NET Framework 3.5 SP1, Microsoft introduced ASP.NET Routing, which decouples the URL of a resource from the physical file on the web server. With ASP.NET Routing you, the developer, define routing rules map route patterns to a class that generates the content. For example, you might indicate that the URL <code>Categories/<i>CategoryName</i></code> maps to a class that takes the <i>CategoryName</i> and generates HTML that lists that category's products in a grid. With such a mapping, users could view products for the Beverages category by visiting <code>www.yoursite.com/Categories/Beverages</code>.In .NET 3.5 SP1, ASP.NET Routing was primarily designed for <a href="http://www.asp.net/mvc/">ASP.NET MVC</a>

• PageMethods In ASP.NET AJAX

  Page Methods is a new mechanism in ASP.NET applications where the server code can be bound to ASP.NET pages. It is an easy way to communicate asynchronously with the server using ASP.NET AJAX technologies. It is an alternate to calling the page which is reliable and carries a low risk. It is basically used to expose the web methods to the client script.

• ASP.NET MVC Cookbook &ndash; public review

  I have recently started writing another book. The topic of this book is ASP.NET MVC. This book differs from my previous book in that rather than working towards building one project from end to end this book will demonstrate specific topics from end to end. It is a recipe book (hence the cookbook name) and will be part of the Packt Publishing cookbook series. An example recipe in this book might be how to consume JSON, creating a master /details page, jquery modal popups, custom ActionResults, etc....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?
