• Simple string encryption in .NET and Javascript

  - by jonathanconway

  I'm developing an ASP.NET MVC application in which I want to encrypt a short string on the server, using C#, and send it to the client-side. Then on the client-side it will be decrypted through Javascript code. Any thoughts on how to implement this? Do you know of a simple encryption algorithm (doesn't have to be bullet-proof secure) that can be easily translated from C# to Javascript or vice-versa? NOTE: I could do this entirely in C# and do the decryption through Ajax, but I'd prefer not to do it this way, as I want to reduce website traffic as much as possible.

• What is the best PHP framework for building a website around a heavily relational PostgreSQL databas

  - by Kenaniah

  First of all, the framework of choice needs to have excellent support for PostgreSQL. I don't care about MySQL because it doesn't have half of the features the application I will be porting requires. (And when I say excellent support, I mean that their approach to database drivers has not been solely trained in MySQL). The ideal framework: Should take full advantage of PHP 5.3 and PostgreSQL 8.4 features Should support new technologies such as OpenID and social networking Should support complex relationships between database relations Should have an intelligent validation system Should have a basic library of helpful views (such as pagination, navigation, etc) Should probably be MVC based Should have excellent documentation and an active development community Should namespace classes intelligently What I'm looking for might be more of a library of utilities, as I really don't want to be restricted by the framework in what I can and can not do. I have my own small library of core classes that take care of business logic, and I will most likely want to integrate those with the new framework as well. Thanks!

• Does NInject work in medium trust hosting?

  - by Gabriel

  I'm doing shared hosting with GoDaddy and I developed a sample ASP.NET MVC app using Castle Windsor and unfortunately, it didn't work in a medium trust setting. Specifically, I got this error: "[SecurityException: That assembly does not allow partially trusted callers"... etc. GoDaddy is sadly not flexible in their trust policy. I'm not tied to Windsor and would like to try another one that will work under Medium Trust. I'd actually like to use NInject, but I've read people having mixed success. The only one I've read that works with no problem is Microsoft's Unity. My question is, does NInject work in medium trust? If not, what are my options?

• .NET Framework 4 RC on Windows server 2008 R2

  - by mare

  I've just installed .NET 4 on Windows SErver 2008 R2 x64 and I am getting 500 Internal Server Error with an ASP.NET MVC application which was previously running fine on 3.5. The application was upgraded from targeting 3.5 to target 4 and I personally built it today on my development machine (changed in VS - Properties to .NET Framework 4). On the server I installed .NET Framework 4 Client profile RC for x86 and x64 platforms and I created a new .NET 4 application pool in IIS and placed the web app in it. Also I have custom errors turned Off in web.config but even so no detailed error is displayed - just the plain IIS 7.5 500 Internal Server Error. Any suggestions?

• Rearranging parts of the URL result from link_to in Rails

  - by mathee

  This is how I'm doing it now: link_to "Profile", :controller => "profiles", :action => "asked", :id => @profile # => <a href="/profiles/asked/1">Profile</a> Does it make more sense for the URL to be <a href="/profiles/1/asked">Profile</a>? Profile 1 asked some number of questions, so it makes more sense to me for the URL to look like: /:controller/:id/:action. If you agree, how do I accomplish this? If you don't agree, please let me know why. (I'm new to Ruby on Rails, so I'm still getting used to MVC conventions.) Any advice would be great!

• How to create a RESTful web service in asp.net?

  - by jonhobbs

  Hi Guys, I simply want to create a fairly basic REST service, so that I can expose some of the data in my asp.net/SQL server application to the outside works, like this..... http://domain.com/api/offices - would return an xml set of office locations. http://domain.com/api/offices/15 - would return all the details of office 15. It's all fairly standard stuff (including basic authentication) but there seem to be several ways to achieve this using Microsoft technologies and I don't really know where to start. These seem to be the options... 1) WCF 2) ASP.NET MVC 3) ADO.NET Data Services 4) Rest Starter Kit project templates? Which of these is the easiest and most "up-to-date" solution to creating a web service?

• Problem with referencing CSS and Javascript files relatively

  - by Markus

  I have an IIS web site. This web site contains other web sites so the structure is like this. \ MainWebSite\ App1\ App2\ All sites are Asp.net MVC Webapplications. In the MasterPage of App1, I reference the script files like this: <script type="text/javascript" src="../../Scripts/jquery-ui-1.8.custom.min.js"> </script> The Problem is that he now tries to find the File at http:\server\MainWebSite\Scripts.... how can i work around that? Should I put all my Scripts and CSS files into the root directory, is that a preferred solution?

• Jquery modal dialog disables its own controls

  - by Anil Soman

  I have a DIV to be shown as modal dialog in my ASP.Net MVC project. This DIV has a textbox to accept user input. However, when I open the dialog with modal option set to true, it disables this textbox as well along with parent form controls! How do I enable the controls on the dialog when open as modal? <div id="assumption-block" class="ic-assumption-block-pos"> <input type="text" id="maxid" value="text" /> </div> Script $('#assumption-block').dialog({modal:true});

• Debugging ASP.NET on a built-in web server suddenly stops

  - by Anton Gogolev

  I have Windows Server 2008 (64-bit), VS 2008 with its built-in webserver and an ASP.NET MVC 1.0 webapp. All I'm trying to do is to debug said app. I have a bunch of breakpoints, but they behave in a very strange way. When I fist start a debugging session with F5 and hit a breakpoint, the debugger stops just fine. However, after serveral F10s/F11s debugging suddenly "stops" (no exceptions at that time), but neither VS detaches from browsers' process, nor webapp execution stops: Visual Studio stays attached, and web request continues executing as usual. I tried various browsers (Chrome, Firefox, IE), but to no avail. What do I do to solve this? It really drives me insane.

• Initiate a PHP class where class name is a variable

  - by ed209

  I need some help with an error I have not encountered before and can't seem to find anywhere. In a PHP mvc framework (just from a tutorial) I have the following: // Initiate the class $className = 'Controller_' . ucfirst($controller); if (class_exists($className)) { $controller = new $className($this->registry); } $className is showing the correct class name (case is also correct). But when I run it I get this in the apache error log (no php error) [Wed Mar 31 10:34:12 2010] [notice] child pid 987 exit signal Segmentation fault (11) Process id is different on every call. I am running PHP 5.3.0 on os x 10.6. This site seems to work on 5.2.11 on another Mac. Not really sure where to go next to debug it. I guess it could be an apache setting as much as a php bug or a problem with the code... any suggestions on where to look next?

• LINQ to SQL: Issue with concurrency

  - by Gib

  I’m working on a sandwich ordering app in ASP.NET MVC, C# and LINQ to SQL. The app revolves around the user creating multiple custom-made sandwiches from a selection of ingredients. When it comes to confirming the order I need to know that there’s enough portions of each ingredient to fulfil all the sandwiches in the user’s order before I commit to the DB as it is possible that an ingredient will go out of stock between adding it to their basket and confirming the order. A bit about the database: Ingredient – Stores ingredient details including number of portions Order – Header table for an order, simply stores the order time OrderDetail – Stores a record of each sandwich in an order OrderDetailItem – Stores each ingredient in each sandwich in an order So basically I’m wondering what the best approach to ensuring that before I add records to Order, OrderDetail and OrderDetailItem I can ensure that the order can be met.

• ASP.NET OutPutCache VaryByParam and VaryByHeader with AJAX

  - by DennyDotNet

  I'm trying to do some caching using VaryByParam AND VaryByHeader. When an AJAX request comes in I return a partial XHTML. When a regular request comes in I send the partial XHTML page with header / footer. I tried to cache the page by doing: [OutputCache( Duration = 5, VaryByParam = "nickname,page", VaryByHeader = "X-Requested-With" )] However this doesn't work... if I do a regular request first then run the AJAX call I get the full cached page instead of the partial and vice-versa. Seems like VaryByHeader is being ignored. Is it because X-Requested-With is omitted on normal requests? Or perhaps it's doing VaryByParam OR VaryByHeader? My obvious way around this is for AJAX requests to call a different method which only returns partial pages, however I'd like to avoid that if possible. I'm using ASP.NET MVC 1.0 with the OutputCacheAttribute.

• How can I change or remove HttpRequest input arguments in a HttpModule

  - by Eric Gunn

  Is it possible to change or remove http request form inputs in an httpmodule? My goal is to create a security IHttpmodule that will check the request for reasonable values, such as limits on acceptable input and query parameter length, or use the AntiXSS Sanitizer to remove threats, log potential hack attempts, etc. before a request is passed on to a processor. Because this is a cross cutting concern I'd prefer to find a solution that applies to all requests and affects all ways request values could be accessed, Reqest.Form, Action(model), Action(FormCollection), HttpContext.Current.Request.Form, etc. I'm using MVC and have considered creating custom model binders to clean the data before creating the model instance. But that would be application specific, require remembering to register every model binder and only apply to Action(model).

• Web2py controllers with parameters?

  - by nickfranceschina

  I am building an app using Web2py framework... I don't want to have to use the request object to get all of the querystring parameters, instead I'd like to build my controller with named parameters and have the router unpack the querystring (or form data) dictionary into the named parameters and call my controller. so instead of a controller method of create_user(): where I would use the global request() object and look through the vars list... I would prefer instead to have create_user(first_name, last_name, email): like I see in other MVC platforms. is this possible in Web2py already? or is there a plugin for it? or do I need to add that myself?

• LINQ to SQL or Entities, at this point?

  - by orlon

  I'm a bit late to the game and have decided to spend some spare time learning LINQ. As an exercise, I'm going to rewrite a WebForms app in MVC 2 (which is also new to me). I managed to find a few topics regarding LINQ here (http://stackoverflow.com/questions/16322/learning-about-linq, http://stackoverflow.com/questions/8050/beginners-guide-to-linq, http://stackoverflow.com/questions/252683/is-linq-to-sql-doa), which brought the concern of Entities vs SQL to my attention. The threads are all over a year old however, and I can't seem to find any definitive information on which ORM is preferable. Is Entities more or less LINQ to SQL 2.0 at this point? Is it still more difficult to use? Is there any reason to use LINQ to SQL, or should I just jump into Entities? The applications I write at my present employer have a lengthy lifecycle (~10 years), so I'm trying to pick the best technology available.

• Is it dangerous to store user-enterable text into a hidden form via javascript?

  - by KallDrexx

  In my asp.net MVC application I am using in place editors to allow users to edit fields without having a standard form view. Unfortunately, since I am using Linq to Sql combined with my data mapping layer I cannot just update one field at a time and instead need to send all fields over at once. So the solution I came up with was to store all my model fields into hidden fields, and provide span tags that contain the visible data (these span tags become editable due to my jquery plugin). When a user triggers a save of their edits of a field, jquery then takes their value and places it in the hidden form, and sends the whole form to the server to commit via ajax. When the data goes into the hidden field originally (page load) and into the span tags the data is properly encoded, but upon the user changing the data in the contenteditable span field, I just run $("#hiddenfield").val($("#spanfield").html(); Am I opening any holes this method? Obviously the server also properly encodes stuff prior to database entry.

• How to make a legacy webapp spring aware at the container level for bean autowire into Servlets?

  - by Pete

  We have a legacy web application (not Spring based) and are looking for best practices to autowire some newer Spring configured (thread safe) service beans into instance variables in several of the legacy servlets. Rewriting every servlet to Spring MVC is out of scope. For testability, we do not want any Spring specific bean lookup code in the Servlets to look up beans by name or similar. Note that we are not concerned about web specific bean scopes such as session or request; all services are singleton scope. Below shows relevant code snippet MyServlet extends LegacyServletSuperclass { private MyThreadSafeServiceBean wantThisToBeAutowiredBySpring; .... }

• What is the best logging solution for a C# .NET 3.5 project?

  - by Odd

  My team is about to start a new enterprise wide ASP.NET development project, quite possibly the largest undertaken by my department so far and the largest project that I've ever worked on. I'm looking for a good logging solution for the system. Firstly, what logging tools are currently available and widely used? Secondly, for an ASP.NET (probably MVC) enterprise applicaiton, which tool is most appropriate based on your experience? So far I've used Log4net almost exclusively for all my previous projects. It's a fantastic tool, however I would like to see if there is anything I've not used out there before I start a project of this magnitude or if there is any reason I would not want to use Log4net for a project of this size.

• What tech stack/platform to use for a project?

  - by danny z

  Hey guys, This is a bit of a weird meta-programming question, but I've realized that my new project doesn't need a full MVC framework, and being a rails guy, I'm not sure what to use now. To give you a gist of the necessary functionality; this website will display static pages, but users will be able to log in and 'edit their current plans'. All purchasing and credit card editing is being handled by a recurring payment subscriber, I just need a page to edit their current plan. All of that will be done through (dynamic) XML API calls, so no database is necessary. Should I stick with my typical rails/nginx stack, or is there something I could use that would lighten the load, since I don't need the Rails heft. I'm familiar with python and PHP but would prefer not to go that route. Is Sinatra a good choice here? tl;dr: What's a good way to quickly serve mostly static pages, preferably in Ruby, with some pages requiring dynamic XML rendering?

• anyone know of a custom membership provider implementation that check password strength against in-b

  - by ronaldwidha

  I've got an Asp.net MVC app and before being able to go live, the IT have requested for us to comply with their password policy. The flexibility of AspnetSqlMembershipProvider doesn’t quite satisfy the requirement. The password strength and length rules are as follows: one lowercase one Uppercase one number and or special character 8 characters in length so far, aspnetsqlmembershipprovider is good... Not allowed to use: Dictionary words Names, real or fictional Plain language phrases Dates Telephone numbers Car registration numbers User IDs Postal codes Organization name Only the first 4 criteria are satisfied by the aspnetsqlmembershipprovider. Do you know of any third party products that offers this functionality (preferably in the form of a custom membership provider)?

• Good portfolio projects

  - by David

  Hi, I am a recent graduate and am looking to start a career in web development. Its kind of a catch 22 at the moment as I have a fair bit of programming experience from university but not really in web development and to get a job in web development a portfolio is typically required. So, I am looking to start a building a few application in order to have something to show potential employers. Im more into the backend stuff although am just as comfortable with front end development. Does anyone have any thoughts on some potential projects that would be both relatively quick (as i need to get a job soon!) to build but show off enough programming knowlege / skills to be impressive to employers. At the moment i am also learning to use the zend framework and I would hope to find work using such a framework (mvc). My initial thoughts would be things like a webmail app or maybe a custom CMS. Any ideas would be greatley appreciated.
