  • SWFUpload Authentication

    - by durilai
    I am using SWFUpload to do file uploading in a ASP.NET MVC 1.0 website. It is working fine, but I am not able to authenticate the upload method. The HttpContext.User.Identity.Name returns an empty string. I am assuming this is because the Flash movie is making the post. I am also using the wrapper provided here: http://blog.codeville.net/2008/11/24/jquery-ajax-uploader-plugin-with-progress-bar/. The controller action below gets fired, but as mentiond above the user object is not passed. Any help is appreciated! View HTML <form enctype="multipart/form-data" method="post" action="/Media/Upload/Photo"> <input type="file" id="userPhoto_Photo" name="userPhoto_Photo" /> </form> Javascript $(function() { $("#userPhoto").makeAsyncUploader({ upload_url: '/Media/Upload', flash_url: '<%= Url.Content("~/Content/Flash/swfUpload-2.2.0.1.swf") %>', file_size_limit: '1 MB', file_types: '*.jpg; *.png; *.gif', button_action: SWFUpload.BUTTON_ACTION.SELECT_FILE, button_width: 210, button_height: 35, button_image_url: '<%= Url.Content("~/Content/Images/UploadPhoto.png") %>', button_text: '', button_cursor: SWFUpload.CURSOR.HAND, button_window_mode: SWFUpload.WINDOW_MODE.TRANSPARENT }); }); Controller Action [AcceptVerbs(HttpVerbs.Post)] public ActionResult Upload() { if (Request.Files.Count == 1) { //Upload work } return RedirectToAction("Index", "Profile"); }

  • Web API Getting Http 500 error : Issue Solved See Below

    - by Joe Grasso
    Here is my MVC Controller and everything is fine: private UnitOfWork UOW; public InventoryController() { UOW = new UnitOfWork(); } // GET: /Inventory/ public ActionResult Index() { var products = UOW.ProductRepository.GetAll().ToList(); return View(products); } Same method call in API Controller gives me an Http 500 Error: private UnitOfWork _unitOfWork; public TestController() { _unitOfWork = new UnitOfWork(); } public IEnumerable<Product> Get() { var products = _unitOfWork.ProductRepository.GetAll().ToList(); return products; } Debugging shows that indeed there is data being returned in both controllers' UOW calls. I then added a customer configuration in Global: public static void CustomizeConfig(HttpConfiguration config) { config.Formatters.Remove(config.Formatters.XmlFormatter); var json = config.Formatters.JsonFormatter; json.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); } I am still receiving an Http 500 in API Controller ONLY and at a loss as to why. Any ideas? UPDATE: It appears using lazy loading caused the problem. When I set the associated properties to NON-VIRTUAL the Test API provided the necessary JSON string. However, whereas before I had the Vendor class included, I only have VendorId. I really wanted to included the associated classes. Any ideas? I know there are alot of smart people out there. Anyone?

  • FormMethod.Get and query string parameters

    - by parminder
    Hi Experts, I am working on a website in asp.net mvc. I have to show a view where user put some search values like tags and titles to search. I want to use the same Index method for that. I have make my form to use formMethod.Get to send the parameters as querystring. so here is the method [HttpGet] public ActionResult Index(string title, string tags, int? page) { if (string.IsNullOrEmpty(title) return View(null); var list = GetSomeData(); return View(list); } here is my view <div id="searchBox"> <% using (Html.BeginForm(null, null, FormMethod.Get)) { %> <table> <tr> <td> <input type="hidden" id="isPosted" name="isPosted" value="1" /> I am looking for <%=Html.TextBox("Title")%> Tags: <%=Html.TextBox("Tags")%> <input id="search" type="submit" value="Search" /> </td> </tr> </table> <% } %> So when the user first visit the page, he will see only two text boxs and a button. but when he types something in the title and tags and click the search button i will load the view with some data. Now the problem is when i type something in title and tags box and click search, they are received in the method, but are not visible in the url. Is there anything i m doing wrong. help will be appreciated. Regards Parminder

  • How to properly develop and deploy features for existing asp.net applications on IIS

    - by Tomh
    My question actually consists of multiple questions. I'm frequently reading about companies who deploy a small subset of features for a select amount of customers using the live "database". Ruby on Rails and its ecosystem have deployment tools and database migrations to deploy or rollback such features in a live production or staging environment. My question, how is this done for an asp.net (mvc in particular) application? How do you test your newly released features against live data? Do you have any tools to modify the existing database and roll back changes if necessary? Do you make backups before deployment? Update Maybe I should point out that my question is not really clear, getting more answers here will help me phrase the question better. To make it easier I will describe a situation I'm commonly seeing with some of my clients. My clients have large deployments of popular web applications. They do not have staging/QA/testing servers. (yes this is not optimal). The data their apps consist of are images, xml files, user uploads and data in Sql Server. Having a few records, of their production database and a couple of dummy files is not a substitute of testing against real data in my opinion. How would you design a workflow that can create a acceptable environment to mimic a production environment before going live?

  • Generating JavaScript in C# and subsequent testing

    - by Codebrain
    We are currently developing an ASP.NET MVC application which makes heavy use of attribute-based metadata to drive the generation of JavaScript. Below is a sample of the type of methods we are writing: function string GetJavascript<T>(string javascriptPresentationFunctionName, string inputId, T model) { return @"function updateFormInputs(value){ $('#" + inputId + @"_SelectedItemState').val(value); $('#" + inputId + @"_Presentation').val(value); } function clearInputs(){ " + helper.ClearHiddenInputs<T>(model) + @" updateFormInputs(''); } function handleJson(json){ clearInputs(); " + helper.UpdateHiddenInputsWithJson<T>("json", model) + @" updateFormInputs(" + javascriptPresentationFunctionName + @"()); " + model.GetCallBackFunctionForJavascript("json") + @" }"; } This method generates some boilerplace and hands off to various other methods which return strings. The whole lot is then returned as a string and written to the output. The question(s) I have are: 1) Is there a nicer way to do this other than using large string blocks? We've considered using a StringBuilder or the Response Stream but it seems quite 'noisy'. Using string.format starts to become difficult to comprehend. 2) How would you go about unit testing this code? It seems a little amateur just doing a string comparison looking for particular output in the string. 3) What about actually testing the eventual JavaScript output? Thanks for your input!

  • SerializationException with custom GenericIdentiy?

    - by MunkiPhD
    I'm trying to implement my own GenericIdentity implementation but keep receiving the following error when it attempts to load the views (I'm using asp.net MVC): System.Runtime.Serialization.SerializationException was unhandled by user code Message="Type is not resolved for member 'OpenIDExtendedIdentity,Training.Web, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'." Source="WebDev.WebHost" I've ended up with the following class: [Serializable] public class OpenIDExtendedIdentity : GenericIdentity { private string _nickName; private int _userId; public OpenIDExtendedIdentity(String name, string nickName, int userId) : base(name, "OpenID") { _nickName = nickName; _userId = userId; } public string NickName { get { return _nickName; } } public int UserID { get { return _userId; } } } In my Global.asax I read a cookie's serialized value into a memory stream and then use that to create my OpenIDExtendedIdentity object. I ended up with this attempt at a solution after countless tries of various sorts. It works correctly up until the point where it attempts to render the views. What I'm essentially attempting to achieve is the ability to do the following (While using the default Role manager from asp.net): User.Identity.UserID User.Identity.NickName ... etc. I've listed some of the sources I've read in my attempt to get this resolved. Some people have reported a Cassini error, but it seems like others have had success implementing this type of custom functionality - thus a boggling of my mind. http://forums.asp.net/p/32497/161775.aspx http://ondotnet.com/pub/a/dotnet/2004/02/02/effectiveformsauth.html http://social.msdn.microsoft.com/Forums/en-US/netfxremoting/thread/e6767ae2-dfbf-445b-9139-93735f1a0f72

  • NHibernate: how to handle entity-based validation using session-per-request pattern, without control

    - by Seth Petry-Johnson
    What is the best way to do entity-based validation (each entity class has an IsValid() method that validates its internal members) in ASP.NET MVC, with a "session-per-request" model, where the controller has zero (or limited) knowledge of the ISession? Here's the pattern I'm using: Get an entity by ID, using an IFooRepository that wraps the current NH session. This returns a connected entity instance. Load the entity with potentially invalid data, coming from the form post. Validate the entity by callings its IsValid() method. If valid, call IFooRepository.Save(entity). Otherwise, display error message. The session is currently opened when the request begins and flushed when the request ends. Since my entity is connected to a session, flushing the session attempts to save the changes even if the object is invalid. What's the best way to keep validation logic in the entity class, limit controller knowledge of NH, and avoid saving invalid changes at the end of a request? Option 1: Explicitly evict on validation failure, implicitly flush: if the validation fails, I could manually evict the invalid object in the action method. If successful, I do nothing and the session is automatically flushed. Con: error prone and counter-intuitive ("I didn't call .Save(), why are my invalid changes being saved anyways?") Option 2: Explicitly flush, do nothing by default: By default I can dispose of the session on request end, only flushing if the controller indicates success. I'd probably create a SaveChanges() method in my base controller that sets a flag indicating success, and then query this flag when closing the session at request end. Pro: More intuitive to troubleshoot if dev forgets this step [relative to option 1] Con: I have to call IRepository.Save(entity)' and SaveChanges(). Option 3: Always work with disconnected objects: I could modify my repositories to return disconnected/transient objects, and modify the Repo.Save() method to re-attach them. Pro: Most intuitive, given that controllers don't know about NH. Con: Does this defeat many of the benefits I'd get from NH?

  • Javascript callback not firing when AJAX operation complete

    - by MisterJames
    Given the following code on an ASP.NET MVC View: <% using (Ajax.BeginForm("AddCommunity", new AjaxOptions { UpdateTargetId = "community-list", OnSuccess = "BindCommunityHover" })) { %> Add Community: <input type="text" id="communityName" name="communityName" /> <input type="submit" value="Add" /> <% } %> And the following JavaScript method in the file: function BindCommunityHover() { $(".community-item-li").hover( function () { $(this).addClass("communityHover"); }, function () { $(this).removeClass("communityHover"); } ); }; Is there any reason why BindCommunityHover is not being called when the AJAX result comes back? The community-list div is properly updated (the action returns a partial view). I have also tried setting OnComplete (instead of OnSuccess) to no avail. The BindCommunityHover method is called in a $(function(){...}); block when the page first loads, and for all existing .community-item-li elements, it works. The partial result from my controller replaces all items in that div with more of the same class. The OnSuccess method is supposed to fire after the document is updated. Update: k...this gets weird. I added the following to the BindCommunityHover method: alert($(".community-item-li").size()); I'm getting 240 in the alert when the page loads and when the callback fires. So, the callback IS firing, jQuery is matching the elements but not applying the styles...

  • 404 Not Found When Requesting URI With Encoded Patameters

    - by Richard Knop
    I am pretty sure this is some problem with the Apache configuration because it used to work on the previous hosting provider with the same PHP/MySQL configuration. In my application, users are able to delete photos by going to URIs like this: http://example.com/my-account/remove-media/id/9/ret/my-account%252Fedit-album%252Fid%252F1 The paramater id is an id of a photo to be removed, the parameter ret is a relative URL where user should be redirected after the removal of the photo but after clicking on a link like that I get 404 Not Found error with the text: Not Found The requested URL /public/my-account/remove-media/id/9/ret/my-account/edit-album/id/1 was not found on this server. Though it used to work on my previous hosting provider so I guess it is just some easy Apache configuration issue? One more thing, there is a htaccess file that changes the document root to /public: RewriteEngine On php_value upload_max_filesize 15M php_value post_max_size 15M php_value max_execution_time 200 php_value max_input_time 200 # Exclude some directories from URI rewriting #RewriteRule ^(dir1|dir2|dir3) - [L] RewriteRule ^\.htaccess$ - [F] RewriteCond %{REQUEST_URI} ="" RewriteRule ^.*$ /public/index.php [NC,L] RewriteCond %{REQUEST_URI} !^/public/.*$ RewriteRule ^(.*)$ /public/$1 RewriteCond %{REQUEST_FILENAME} -f RewriteRule ^.*$ - [NC,L] RewriteRule ^public/.*$ /public/index.php [NC,L] In the public folder there is a second htaccess file for MVC: RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ /index.php [NC,L] # Turn off magic quotes #php_flag magic_quotes_gpc off

I have the following code in the View: <% using(Html.BeginForm(null, "Home", FormMethod.Post, new{id="formcpf"})){ %> <p> <input name="tipo" type="radio" value="GeraCPF" /> CPF <input type="radio" name="tipo" value="GeraCNPJ" /> CNPJ </p> <p> <input type="submit" id="sbmt" value="Gerar" /> <br /><br /> <span id="lblCPF" class="respostaBG"></span> </p> <%} % and the following Javascript to call an Ajax request: $(document).ready(function() { $("form#formcpf").submit(function(event) { $(this).attr("action", $("input[@name='tipo']:checked").val()); event.preventDefault(); hijack(this, update_sessions, "html"); }); }); function hijack(form, callback, format) { $.ajax({ url: form.action, type: form.method, dataType: format, data: $(form).serialize(), success: callback }); } function update_sessions(result) { $("#lblCPF").html(result); } in Firefox and Chrome works fine, but in IE7 sometimes returns the value into the label, sometimes not. I have to keep submiting to get the return. Anyone could help?

    Symptoms In IIS Dot Net 2.0 Integrated app pool: double clicking to view any web.config section results in a the following error dialog. "There was an error while performing this operation.... Fielname... web.config... Error: There is a duplicate..." Browsing to the URL displays: "Http 500.19" internal server error.. There is a duplicate... 'system.web.extensions/scripting/scriptResourceHandler' section defined...." Running the app from VS 2008 an "Unable to start debugging on the web server..." dialog is displayed. Things Tried Looked at other application directories on same IIS server. No problem view web.config contents or serving up the app. Removed and re-added the application in IIS. Checked out a new version of the source code. Reverted to prior versions of the web.config file. Looked for web.config files that might have duplicate sections in: Inetpub root. "C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config" The "Views" subfolder of the ASP.Net MVC app. Checked out source code to another dev machine. Setup IIS 7 app folder. No problem with Web.config. Question If the reason for this error is another web.config file where else should I look? Are there other reasons for these symptoms?

  • IHttpModule not being applied to virtual directory

    - by arthurdent510
    I have a network folder that is mapped to my iis app as a virtual directory and I'm trying to do some authentication for files that are located there with an ihttpmodule. I've verified that the ihttpmodule is firing properly for anything else in my app, just not the files located in virtual directory. Most of what I've found is that the directory can't be listed as an application (which it isn't), and everything should work. The other solution that I found was to add the the module tag to the tag, but that didn't seem to help either. Everything that I've found talks about stopping this from happening. So my question is what could be set that is causing this to not work? Is there a certain execute permission that needs to be set? Any other iis settings that could cause this? It is an mvc app, and this is how my directory structure is laid out: server/app <- my application folder server/app/content/downloads <- downloads is the virtual directory Do I have to add the virtual directory directly under my app directory? Is that part of the problem? I don't have direct control of the server my code is running on, so testing things out is a bit of a pain... so I was looking for some more thoughts before starting to send emails off to my operations people. Thanks!

  • Important question about linq to SQL performance on high loaded web applications

    - by Alex
    I started working with linq to SQL several weeks ago. I got really tired of working with SQL server directly through the SQL queries (sqldatareader, sqlcommand and all this good stuff).  After hearing about linq to SQL and mvc I quickly moved all my projects to these technologies. I expected linq to SQL work slower but it suprisongly turned out to be pretty fast, primarily because I always forgot to close my connections when using datareaders. Now I don't have to worry about it. But there's one problem that really bothers me. There's one page that's requested thousands of times a day. The system gets data in the beginning, works with it and updates it. Primarily the updates are ++ @ -- (increase and decrease values). I used to do it like this UPDATE table SET value=value+1 WHERE ID=@I'd It worked with no problems obviously. But with linq to SQL the data is taken in the beginning, moved to the class, changed and then saved. Stats.registeredusers++; Db.submitchanges(); Let's say there were 100 000 users. Linq will say "let it be 100 001" instead of "let it be increased by 1". But if there value of users has already been increased (that happens in my site all the time) then linq will be like oops, this value is already 100 001. Whatever I'll throw an exception" You can change this behavior so that it won't throw an exception but it still will not set the value to 100 002. Like I said, it happened with me all the time. The stas value was increased twice a second on average. I simply had to rewrite this chunk of code with classic ado net. So my question is how can you solve the problem with linq

  • My framework will utilise other frameworks, but I'd like this to be transparent to the end-user

    - by d11wtq
    I'm building a framework, which aims to provide a new development environment for the user, but I need to use things like RegexKit and almost certainly some other established frameworks in order to do this. Any functionality exposed from such frameworks would be abstracted through classes and methods in my own framework for maintenance reasons (allowing me to change my mind on which dependencies I want). In an ideal world I just want to ship a single .framework. However I'm aware that unlike with standard bundles and applications it is not possibile to embed a framework inside the framework bundle. Do I have any other option other than to tell the end user that they must also install RegexKit and any other dependencies? I have a feeling this lessens the appeal value of the easy to use embedded framework I'd envisaged building. Right now I'm feeling like I have some limited options: Force the user to install the dependencies. Write my own classes that provide the same functionality -- ugh! If at all possible, try to statically link the third party frameworks (is this possible??) My end-product is ideally a single .framework bundle that uses @rpath and so can be installed in the system or simply bundled with the app that uses it.

  • Model binding & derived model classes

    - by Richard Ev
    Does ASP.NET MVC offer any simple way to get model binding to work when you have model classes that inherit from others? In my scenario I have a View that is strongly typed to List<Person>. I have a couple of classes that inherit from Person, namely PersonTypeOne and PersonTypeTwo. I have three strongly typed partial views with names that match these class names (and render form elements for the properties of their respective models). This means that in my main View I can have the following code: <% for(int i = 0; i < Model.Count; i++) { Html.RenderPartial(Model[i].GetType().Name, Model[i]); } %> This works well, apart from when the user submits the form the relevant controller action method just gets a List<Person>, rather than a list of Person, PersonTypeOne and PersonTypeTwo. This is pretty much as expected as the form submission doesn't contain enough information to tell the default model binder to create any instances of PersonTypeOne and PersonTypeTwo classes. So, is there any way to get such functionality from the default model binder?

  • Binding, Prefixes and generated HTML

    - by Vman
    MVC newbie question re binders. Supposing I have two strongly typed partial actions that happen to have a model attributes with the same name, and are rendered in the same containing page i.e.: Class Friend {string Name {get; set ;} DateTime DOB {get; set ;}} Class Foe {string Name {get; set ;} string ReasonForDislike {get; set ;}} Both partials will have a line: <%= Html.TextBoxFor(model => model.Name) %> And associated controller actions: public ActionResult SaveFriend(Friend friend) public ActionResult SaveFoe(Foe foe) My problem is that both will render on my containing page with the same id (of course, bad for lots of reasons). I’m aware of the [Bind] attribute that allows me add a prefix, resulting in code: public ActionResult SaveFriend([Bind(Prefix = “friend”)] Friend friend) <%= Html.TextBox("friend.Name", Model. Name) %> //Boo, no TextBoxFor :( But this still doesn’t cut it. I can just about tolerate the loss of the strongly typed TextBoxFor helpers but I’ve yet to get clientside validation to work with prefixes: I’ve tried: <%= Html.ValidationMessage("friend.Name") %> ...and every other variant I can think of. I seem to need the model to be aware of the prefix in both directions but bind only applies when mapping the inbound request. It seems (to me) a common scenario but I’m struggling to find examples out there. What am I missing! Thanks in advance.

  • Are dots legal in the name property of an HTML button

    - by justSteve
    a page with a bit of MVC code: <%=Html.SubmitButton("ChooseWebinar.Submit", "Continue to Registration Details")%><br/> that generates an input button where the '.' is embedded in the name: [rendered html] At page load this control (the submit button) is hidden - when one of two different dropdowns registers a value, the button is shown: function toggleChooseWebinarSubmit() { if ($("#ChooseWebinar_RecordedWebinarId").val() || $("#ChooseWebinar_UpcomingWebinarId").val()) { $("#ChooseWebinar_Submit").show(); } else { $("#ChooseWebinar_Submit").hide(); } I've just received a report from an IE8 user who says that after selecting a value in a dropdown, the button is _not displaying. I can't reproduce the condition (i've tried compatibility mode too). Obviously the show/hide is targeting the 'ID' selector but i can't help but wonder about that period in the control's name. Any known issues? - or perhaps the .change is problematic and the toggle's never getting called: $(window).load(function() { toggleChooseWebinarSubmit(); $("#ChooseWebinar_UpcomingWebinarId").change(function() { if ($(this).val()) { $("#ChooseWebinar_RecordedWebinarId").val(""); } toggleChooseWebinarSubmit(); }); $("#ChooseWebinar_RecordedWebinarId").change(function() { if ($(this).val()) { $("#ChooseWebinar_UpcomingWebinarId").val(""); } toggleChooseWebinarSubmit(); }); }); thx

  • How would the 'Model' in a Rails-type webapp be implemented in a functional programming langauge?

    - by ceptorial
    In MVC web development frameworks such as Ruby on Rails, Django, and CakePHP, HTTP requests are routed to controllers, which fetch objects which are usually persisted to a backend database store. These objects represent things like users, blog posts, etc., and often contain logic within their methods for permissions, fetching and/or mutating other objects, validation, etc. These frameworks are all very much object oriented. I've been reading up recently on functional programming and it seems to tout tremendous benefits such as testability, conciseness, modularity, etc. However most of the examples I've seen for functional programming implement trivial functionality like quicksort or the fibonnacci sequence, not complex webapps. I've looked at a few 'functional' web frameworks, and they all seem to implement the view and controller just fine, but largely skip over the whole 'model' and 'persistence' part. (I'm talking more about frameworks like Compojure which are supposed to be purely functional, versus something Lift which conveniently seems to use the OO part of Scala for the model -- but correct me if I'm wrong here.) I haven't seen a good explanation of how functional programming can be used to provide the metaphor that OO programming provides, i.e. tables map to objects, and objects can have methods which provide powerful, encapsulated logic such as permissioning and validation. Also the whole concept of using SQL queries to persist data seems to violate the whole 'side effects' concept. Could someone provide an explanation of how the 'model' layer would be implemented in a functionally programmed web framework?

  • Using ControllerClassNameHandlerMapping with @Controller and extending AbstractController

    - by whiskerz
    Hey there, actually I thought I was trying something really simple. ControllerClassNameHandlerMapping sounded great to produce a small spring webapp using a very lean configuration. Just annotate the Controller with @Controller, have it extend AbstractController and the configuration shouldn't need more than this <context:component-scan base-package="test.mypackage.controller" /> <bean id="urlMapping" class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" /> to resolve my requests and map them to my controllers. I've mapped the servlet to "*.spring", and calling <approot>/hello.spring All I ever get is an error stating that no mapping was found. If however I extend the MultiActionController, and do something like <approot>/hello/hello.spring it works. Which somehow irritates me, as I would have thought that if that is working, why didn't my first try? Does anyone have any idea? The two controllers I used looked like this @Controller public class HelloController extends AbstractController { @Override protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView modelAndView = new ModelAndView("hello"); modelAndView.addObject("message", "Hello World!"); return modelAndView; } } and @Controller public class HelloController extends MultiActionController { public ModelAndView hello(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView modelAndView = new ModelAndView("hello"); modelAndView.addObject("message", "Hello World!"); return modelAndView; } }

  • Hibernate design to speed up querying of large dataset

    - by paddydub
    I currently have the below tables representing a bus network mapped in hibernate, accessed from a Spring MVC based bus route planner I'm trying to make my route planner application perform faster, I load all the above tables into Lists to perform the route planner logic. I would appreciate if anyone has any ideas of how to speed my performace Or any suggestions of another method to approach this problem of handling a large set of data Coordinate Connections Table (INT,INT,INT, DOUBLE)( Containing 50,000 Coordinate Connections) ID, FROMCOORDID, TOCOORDID, DISTANCE 1 1 2 0.383657 2 1 17 0.173201 3 1 63 0.258781 4 1 64 0.013726 5 1 65 0.459829 6 1 95 0.458769 Coordinate Table (INT,DECIMAL, DECIMAL) (Containing 4700 Coordinates) ID , LAT, LNG 0 59.352669 -7.264341 1 59.352669 -7.264341 2 59.350012 -7.260653 3 59.337585 -7.189798 4 59.339221 -7.193582 5 59.341408 -7.205888 Bus Stop Table (INT, INT, INT)(Containing 15000 Stops) StopID RouteID COORDINATEID 1000100001 100 17 1000100002 100 18 1000100003 100 19 1000100004 100 20 1000100005 100 21 1000100006 100 22 1000100007 100 23 This is how long it takes to load all the data from each table: stop.findAll = 148ms, stops.size: 15670 Hibernate: select coordinate0_.COORDINATEID as COORDINA1_2_, coordinate0_.LAT as LAT2_, coordinate0_.LNG as LNG2_ from COORDINATES coordinate0_ coord.findAll = 51ms , coordinates.size: 4704 Hibernate: select coordconne0_.COORDCONNECTIONID as COORDCON1_3_, coordconne0_.DISTANCE as DISTANCE3_, coordconne0_.FROMCOORDID as FROMCOOR3_3_, coordconne0_.TOCOORDID as TOCOORDID3_ from COORDCONNECTIONS coordconne0_ coordinateConnectionDao.findAll = 238ms ; coordConnectioninates.size:48132 Hibernate Annotations @Entity @Table(name = "STOPS") public class Stop implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "STOPID") private int stopID; @Column(name = "ROUTEID", nullable = false) private int routeID; @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "COORDINATEID", nullable = false) private Coordinate coordinate; } @Table(name = "COORDINATES") public class Coordinate { @Id @GeneratedValue @Column(name = "COORDINATEID") private int CoordinateID; @Column(name = "LAT") private double latitude; @Column(name = "LNG") private double longitude; } @Entity @Table(name = "COORDCONNECTIONS") public class CoordConnection { @Id @GeneratedValue @Column(name = "COORDCONNECTIONID") private int CoordinateID; @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "FROMCOORDID", nullable = false) private Coordinate fromCoordID; @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "TOCOORDID", nullable = false) private Coordinate toCoordID; @Column(name = "DISTANCE", nullable = false) private double distance; }

  • Asp.net Web Site Administration Tool with SqlCeMembership

    - by Riderman de Sousa Barbosa
    I am developing an application in MVC 3. I installed this provider via Nuget . Basically, it allows to use any part of memberships, rules and profiles with a .sdf (compact) database. I need the "Web Site Administration Tool" use this provider. But I can not use it. Already checked the web.config and everything is ok. When I open the "Web Site Administration Tool" on the Security I click test (any provider) and the error happens. The following images. Error when clicking test "Could not establish a connection to the database. If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider." Here part of my web.config <authentication mode="Forms" /> <membership> <providers> <add connectionStringName="SqlCeServices" applicationName="/" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="true" passwordFormat="Hashed" writeExceptionsToEventLog="false" name="SqlCeMembershipProvider" type="ErikEJ.SqlCeMembershipProvider, ErikEJ.SqlCeMembership" /> </providers> </membership> <profile enabled="false"> <providers> <clear /> <add name="SqlCeProfileProvider" type="ErikEJ.SqlCeProfileProvider" connectionStringName="SqlCeServices" applicationName="/" /> </providers> </profile> <roleManager> <providers> <add connectionStringName="SqlCeServices" applicationName="/" writeExceptionsToEventLog="false" name="SqlCeRoleProvider" type="ErikEJ.SqlCeRoleProvider, ErikEJ.SqlCeMembership" /> </providers> </roleManager> <connectionStrings> <add name="SqlCeServices" connectionString="data source=|DataDirectory|\SqlCeAspnetdb.sdf" /> </connectionStrings>

  • ASP.NET MVC2 and Browser Caching

    - by Dan
    Hi I have a web application that fetches a lot of content via ajax. For example when a user edits some data, the browser will send the changes using an ajax post and then do an ajax get to get fresh content and replace an existing div on the page with that content. This was working just find with MVC1, but in MVC2 I would get inconsistent results. I've found that MVC1 by default included an Expires item in the response headers set to the current time, but in MVC2 the Expires header is missing. This is a problem with some browsers (IE8) actually using the cached version of the ajax get instead of the fresh version. To deal with the problem I created a simple ActionFilterAttribute that sets the reponse cache to NoCache (see below), which works, but it seems kind of sillly to decorate every controller with this attribute. Is there a global way to set this for every controller? Is this a bug in MVC2 and it really should be setting the expires on every ActionResult/view/page? Don't most MVC programs deal with data entry where stale data is a very bad thing? Thanks Dan public class ResponseNoCachingAttribute : ActionFilterAttribute { public override void OnResultExecuted(ResultExecutedContext filterContext) { base.OnResultExecuted(filterContext); filterContext.HttpContext.Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache); } }

  • Architecture for new ASP.NET web application

    - by Anders Abel
    I'm maintaining an application which currently is just a web service (built with WCF) and a database backend. The web service is built in layers with a linq-to-sql data access part with core functionality in an own assembly and on top of that the web service assembly which contains the WCF code. The core assembly also handles all business logic rules (very few actually). The customer now wants a Web interface for the application instead of just accessing it through other applications which are consuming the web service. I'm quite lost on modern web application design, so I would like some advice on what architecture and frameworks to use for the web application. The web application will be using the same core assembly with business rules and the linq-to-sql data access layer as the web service. Some concepts I've thought about are: ASP.NET MVC Webforms AJAX controls - possibly leting the AJAX controls access the existing web service through JSON. Are there any more concepts I should look into? Which one is the best for a fresh project? The development tools are Visual Studio 2008 Team Edition for Developers targeting .NET 3.5. An upgrade to Visual Studio 2010 Premium (or maybe even Ultimate) is possible if it gives any benefits.
