  • Can't get jQuery AutoComplete to work with External JSON

    - by rockinthesixstring
    I'm working on an ASP.NET app where I'm in need of jQuery AutoComplete. Currently there is nothing happening when I type data into the txt63 input box (and before you flame me for using a name like txt63, I know, I know... but it's not my call :D ). Here's my javascript code <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/jquery-ui.min.js" type="text/javascript"></script> <script src="http://jquery-ui.googlecode.com/svn/tags/latest/external/jquery.bgiframe-2.1.1.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/i18n/jquery-ui-i18n.min.js" type="text/javascript"></script> <script language="javascript" type="text/javascript"> var theSource = '../RegionsAutoComplete.axd?PID=<%= hidden62.value %>' $(function () { $('#<%= txt63.ClientID %>').autocomplete({ source: theSource, minLength: 2, select: function (event, ui) { $('#<%= hidden63.ClientID %>').val(ui.item.id); } }); }); and here is my HTTP Handler Namespace BT.Handlers Public Class RegionsAutoComplete : Implements IHttpHandler Public ReadOnly Property IsReusable() As Boolean Implements System.Web.IHttpHandler.IsReusable Get Return False End Get End Property Public Sub ProcessRequest(ByVal context As System.Web.HttpContext) Implements System.Web.IHttpHandler.ProcessRequest 'the page contenttype is plain text context.Response.ContentType = "application/json" context.Response.ContentEncoding = Encoding.UTF8 'set page caching context.Response.Cache.SetExpires(DateTime.Now.AddHours(24)) context.Response.Cache.SetCacheability(HttpCacheability.Public) context.Response.Cache.SetSlidingExpiration(True) context.Response.Cache.VaryByParams("PID") = True Try ' use the RegionsDataContext Using RegionDC As New DAL.RegionsDataContext ' query the database based on the querysting PID Dim q = (From r In RegionDC.bt_Regions _ Where r.PID = context.Request.QueryString("PID") _ Select r.Region, r.ID) ' now we loop through the array ' and write out the ressults Dim sb As New StringBuilder sb.Append("{") For Each item In q sb.Append("""" & item.Region & """: """ & item.ID & """,") Next sb.Append("}") context.Response.Write(sb.ToString) End Using Catch ex As Exception HealthMonitor.Log(ex, False, "This error occurred while populating the autocomplete handler") End Try End Sub End Class End Namespace The rest of my ASPX page has the appropriate controls as I had this working with the old version of the jQuery library. I'm trying to get it working with the new one because I heard that the "dev" CDN was going to be obsolete. Any help or direction will be greatly appreciated.

  • Need Help with Page Life Cycle(I think it is screwing me up)

    - by chobo2
    Hi I have dragged a empty asp.net table onto my webform. I generate all the rows in the code behind those. Now my table gets filled up and has dropdown lists. When the user hits save I go through all the rows and update the values from the dropdownlist in the db. This works all great. However if 2 columns have each have "Present" then those 2 columns should be not be shown anymore and 2 new columns get put in its place with other dropdown lists. This all works. However you have to refresh the entire page to for the 2 columns that should go away to go away. So what I tried to do is at the end of the button click event. Clear the whole table and then regenerate it. However when I do this then my values are not saved to the database anymore for whatever reason. if (IsPostBack == false) { // check if dummy variables exist in db- If true just generate tables with values in db. If not generate them. } else { // grab the values from the database // generate tables with the values } btn click event { go through all rows in table(foreach loop) update each column in the database with cells in each row. while in foreach loop. //done } So this is how it goes and it works expect(all correct values are saved) the table is just not updated to the user. Does not work if (IsPostBack == false) { // same code as above } // if postback is true do nothing. By the time it gets to the click event it says there is zero rows in the table so nothing happens. btn click event { // same code } Fails also. if (IsPostBack == false) { // same code as above } else { // same code as above but moved into its own method. gernerateTable(); } btn click event { // update all rows // once done clear the Tables rows // call generateTable() } This last one does nothing as for some reason it does not update anything. I don't understand why. So what am I doing wrong with this life cycle something in my process is wrong. The code works just not when I want the table to be updated right away.

  • Model Binding with Parent/Child Relationship

    - by user296297
    I'm sure this has been answered before, but I've spent the last three hours looking for an acceptable solution and have been unable to find anything, so I apologize for what I'm sure is a repeat. I have two domain objects, Player and Position. Player's have a Position. My domain objects are POCOs tied to my database with NHibernate. I have an Add action that takes a Player, so I'm using the built in model binding. On my view I have a drop down list that lets a user select the Position for the Player. The value of the drop down list is the Id of the position. Everything gets populated correctly except that my Position object fails validation (ModelState.IsValid) because at the point of model binding it only has an Id and none of it's other required attributes. What is the preferred solution for solving this with ASP.NET MVC 2? Solutions I've tried... Fetch the Position from the database based on the Id before ModelState.IsValid is called in the Add action of my controller. I can't get the model to run the validation again, so ModelState.IsValid always returns false. Create a custom ModelBinder that inherits from the default binder and fetch the Position from the database after the base binder is called. The ModelBinder seems to be doing the validation so if I use anything from the default binder I'm hosed. Which means I have to completely roll my own binder and grab every value from the form...this seems really wrong and inefficient for such a common use-case. Solutions I think might work, I just can't figure out how to do... Turn off the validation for the Position class when used in Player. Write a custom ModelBinder leverages the default binder for most of the property binding, but lets me get the Position from the database BEFORE the default binder runs validation. So, how do the rest of you solve this? Thanks, Dan P.S. In my opinion having a PositionId on Player just for this case is not a good solution. There has to be solvable in a more elegant fashion.

  • Applying styles to a GridView matching certain criteria

    - by NickK
    Hi everyone. I'm fairly new to ASP.Net so it's probably just me being a bit stupid, but I just can't figure out why this isn't working. Basically, I have a GridView control (GridView1) on a page which is reading from a database. I already have a CSS style applied to the GridView and all I want to do is change the background image applied in the style depending on if a certain cell has data in it or not. The way I'm trying to handle this change is updating the CSS class applied to each row through C#. I have the code below doing this: protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { GridViewRow row = e.Row; string s = row.Cells[7].Text; if (s.Length > 0) { row.CssClass = "newRowBackground"; } else { row.CssClass = "oldRowBackground"; } } In theory, the data from Cell[7] will either be null or be a string (in this case, likely a person's name). The problem is that when the page loads, every row in the GridView has the new style applied to it, whether it's empty or not. However, when I change it to use hard coded examples, it works fine. So for example, the below would work exactly how I want it to: protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { GridViewRow row = e.Row; string s = row.Cells[7].Text; if (s == "Smith") //Matching a name in one of the rows { row.CssClass = "newRowBackground"; } else { row.CssClass = "oldRowBackground"; } } It seems as if the top piece of code is always returning the string with a value greater than 0, but when I check the database the fields are all null (except for my test record of "Smith"). I'm probably doing something very simple that's wrong here, but I can't see what. Like I said, I'm still very new to this. One thing I have tried is changing the argument in the if statement to things like: if (s != null), if (s != "") and if (s == string.empty) all with no luck. Any help is greatly appreciated and don't hesitate to tell me if I'm just being stupid here. :)

  • jquery validation plugin doesn't seem to work ....

    - by Pandiya Chendur
    asp.net mvc's Html.BeginForm() seems to work with jquery validation plugin but the validation plugin doesn't seem to work with a form which i ve added to a page.... This works, <% using (Html.BeginForm("Login", "Registration", FormMethod.Post, new { id = "Loginform" })) {%> <fieldset> <legend>Login</legend> <p> <label for="EmailId">EmailId:</label> <%= Html.TextBox("EmailId", null, new { @class = "text_box_height_14_width_150" })%> </p> <div class="status"></div> <p> <label for="Password">Password:</label> <%= Html.Password("Password",null, new { @class = "text_box_height_14_width_150" }) %> </p> <div class="status"></div> <p> <input type="submit" value="Login" id="login" /> </p> </fieldset> <% } %> But this doesn't work, <form id="Loginform" method="post" action="Registration/Login"> <table cellpadding="0" cellspacing="0" width="100%" style="border:none;"> <tr> <td width="12%">Email Id&nbsp;:&nbsp;</td><td width="15%"> <input id="EmailId" type="text" class="text_box_height_14_width_150 name="EmailId" /></td><td width="20%" class="status"></td> <td width="12%">Password&nbsp;:&nbsp;<td width="15%"><input id="Password" type="password" class="text_box_height_14_width_150 name="Password" /></td> <td width="20%" class="status"></td> <td width="5%"><input type="submit" value="Login" id="BtnLogin" /></td> </tr> </table> </form> and my jquery function has this, $(document).ready(function() { var validator = $("#Loginform").validate({ rules: { EmailId: "required", Password: { required: true, minlength: 6 } }, messages: { EmailId: "Enter your EMail ID", Password: { required: "Please Provide a password", rangelength: jQuery.format("Enter at least {0} characters") } }, // the errorPlacement has to take the table layout into account errorPlacement: function(error, element) { error.appendTo(element.parent().next()); }, // set this class to error-labels to indicate valid fields success: function(label) { // set &nbsp; as text for IE label.html("&nbsp;").addClass("checked"); } }); }); Any suggestion...

  • Which is the "best" data access framework/approach for C# and .NET?

    - by Frans
    (EDIT: I made it a community wiki as it is more suited to a collaborative format.) There are a plethora of ways to access SQL Server and other databases from .NET. All have their pros and cons and it will never be a simple question of which is "best" - the answer will always be "it depends". However, I am looking for a comparison at a high level of the different approaches and frameworks in the context of different levels of systems. For example, I would imagine that for a quick-and-dirty Web 2.0 application the answer would be very different from an in-house Enterprise-level CRUD application. I am aware that there are numerous questions on Stack Overflow dealing with subsets of this question, but I think it would be useful to try to build a summary comparison. I will endeavour to update the question with corrections and clarifications as we go. So far, this is my understanding at a high level - but I am sure it is wrong... I am primarily focusing on the Microsoft approaches to keep this focused. ADO.NET Entity Framework Database agnostic Good because it allows swapping backends in and out Bad because it can hit performance and database vendors are not too happy about it Seems to be MS's preferred route for the future Complicated to learn (though, see 267357) It is accessed through LINQ to Entities so provides ORM, thus allowing abstraction in your code LINQ to SQL Uncertain future (see Is LINQ to SQL truly dead?) Easy to learn (?) Only works with MS SQL Server See also Pros and cons of LINQ "Standard" ADO.NET No ORM No abstraction so you are back to "roll your own" and play with dynamically generated SQL Direct access, allows potentially better performance This ties in to the age-old debate of whether to focus on objects or relational data, to which the answer of course is "it depends on where the bulk of the work is" and since that is an unanswerable question hopefully we don't have to go in to that too much. IMHO, if your application is primarily manipulating large amounts of data, it does not make sense to abstract it too much into objects in the front-end code, you are better off using stored procedures and dynamic SQL to do as much of the work as possible on the back-end. Whereas, if you primarily have user interaction which causes database interaction at the level of tens or hundreds of rows then ORM makes complete sense. So, I guess my argument for good old-fashioned ADO.NET would be in the case where you manipulate and modify large datasets, in which case you will benefit from the direct access to the backend. Another case, of course, is where you have to access a legacy database that is already guarded by stored procedures. ASP.NET Data Source Controls Are these something altogether different or just a layer over standard ADO.NET? - Would you really use these if you had a DAL or if you implemented LINQ or Entities? NHibernate Seems to be a very powerful and powerful ORM? Open source Some other relevant links; NHibernate or LINQ to SQL Entity Framework vs LINQ to SQL

  • Passing ViewModel for backbone.js from MVC3 Server-Side

    - by Roman
    In ASP.NET MVC there is Model, View and Controller. MODEL represents entities which are stored in database and essentially is all the data used in a application (for example, generated by EntityFramework, "DB First" approach). Not all data from model you want to show in the view (for example, hashs of passwords). So you create VIEW MODEL, each for every strongly-typed-razor-view you have in application. Like this: using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace MyProject.ViewModels.SomeController.SomeAction { public class ViewModel { public ViewModel() { Entities1 = new List<ViewEntity1>(); Entities2 = new List<ViewEntity2>(); } public List<ViewEntity1> Entities1 { get; set; } public List<ViewEntity2> Entities2 { get; set; } } public class ViewEntity1 { //some properties from original DB-entity you want to show } public class ViewEntity2 { } } When you create complex client-side interfaces (I do), you use some pattern for javascript on client, MVC or MVVM (I know only these). So, with MVC on client you have another model (Backbone.Model for example), which is third model in application. It is a bit much. Why don`t we use the same ViewModel model on a client (in backbone.js or another framework)? Is there a way to transfer CS-coded model to JS-coded? Like in MVVM pattern, with knockout.js, when you can do like this: in SomeAction.cshtml: <div style="display: none;" id="view_model">@Json.Encode(Model)</div> after that in Javascript-code var ViewModel = ko.mapping.fromJSON($("#view_model").get(0).innerHTML); now you can extend your ViewModel with some actions, event handlers, etc: ko.utils.extend(ViewModel, { some_function: function () { //some code } }); So, we are not building the same view model on the client again, we are transferring existing view model from server. At least, data. But knockout.js is not suitable for me, you can`t build complex UI with it, it is just data-binding. I need something more structural, like backbone.js. The only way to build ViewModel for backbone.js I can see now is re-writing same ViewModel in JS from server with hands. Is there any ways to transfer it from server? To reuse the same viewmodel on server view and client view?

  • IE7 and 8 Hangs Randomly on CSS Images

    - by BJ Safdie
    We have an ASP.NET 3.5 application that has been in production for over a year. Our last release was a couple of months ago. We use CSS for styling and application of background images to divs and such. The server is Windows 2003 with IIS. Suddenly, this week, we have had reports from some users that the page seems to hang up while loading. The status bar was showing the name of a background image used in the page main area (assigned in CSS). At our office, some of us could recreate the problem, while others could not. IE6 and Firefox do not seem to be affected, only IE7/8. Running Fiddler on an affected machine and trying to see what was happening with the requests seemed to make the problem go away (while running through Fiddler, it returned when not). Hitting Refresh on a hung load often made the page load just fine. I checked the background image, and even replaced it with an archived copy. No joy. We re-deployed the app from our production source. No Joy. We restarted IIS and eventually rebooted the whole server. There are no unusual entries in the event logs, the app logs or the IIS logs. Finally, I removed the image entirely and re-styled the page not to use a background image. That solved the problem at least for now. However, we have reports of other images "hanging." The images are PNGs, but I have heard some rumors that sometimes a GIF hangs, but I have no screenshot to confirm. This just started happening "out of the blue." There have been no releases or updates applied to the server recently. We even checked updates on clients to see if a recent Windows Update might have caused this on the client, but there was nothing updated within the last couple of weeks. If you have any information about this problem, I would love to hear from you. I would also greatly appreciate any recommendations on additional diagnostics we can try.

  • Architecture Suggestions/Recommendations for a Web Application with Sub-Apps

    - by user579218
    Hello. I’m starting to plan an architecture for a big web application, and I wanted to get suggestions and/or recommendations on where to begin and which technologies and/or frameworks to use. The application will be an Intranet-based web site using Windows authentication, running on IIS and using SQL Server and ASP.NET. It’ll need to be structured as a main/shell application with sub-applications that are “pluggable” based on some configuration settings. The main or shell application is to provide the overall user interface structure – header/footer, dynamically built tabs for each available sub-app, and a content area in which the sub-application will be loaded when the user clicks on the sub-application’s tab. So, on start-up of the main/shell application, configuration information will be queried from a database, and, based on the user and which of the sub-apps are available, the main or shell app would dynamically build tabs (or buttons or something) as a way to access each individual application. On start-up, the content area will be populated with the “home” sub-app. But, clicking on an sub-app tab will cause the content area to be populated with the sub-app corresponding to the tab. For example, we’re going to have a reports application, a display application, and probably a couple other distinct applications. On startup of the main/shell application, after determining who the user is, the main app will query the database to determine which sub-apps the user can use and build out the UI. Then the user can navigate between available sub-apps and do their work in each. Finally, the entire app and all sub-apps need to be a layered design with presentation, service, business, and data access layers, as well as cross-cutting objects for things such as logging, exception handling, etc. Anyway, my questions revolve around where to begin to plan something like this application. What technologies/frameworks would work best in developing a solution for this application? MVC? MVP? WCSF? EF? NHibernate? Enterprise Library? Repository Pattern? Others???? I know all these technologies/frameworks are not used for the same purpose, but knowing which ones to focus on is a little overwhelming. Which ones would be the best choice(s) for a solution? Which ones work well together for an end-to-end design? How would one structure the VS project for something like this? Thanks!

  • Unable to find assembly, C#

    - by PlasmaCube
    So, here's the deal. I've got two ASP.NET applications, both of which use SQLServer Session State management. They also both use the same server. I've got a custom session class in an external DLL, which fully implements serialization, and which both applications have referenced. Each application, in turn, has a class which inherits from the DLL class, and both applications use their own respective classes for their session state. Now, what I was trying to accomplish was that if you wanted to go to the other application, it could look in the session (they all use the same session key) and treat the existing object there as the base (the one from the DLL), extract whatever login info you need, then overwrite the session object with your own. Unfortunately, when the second application attempts to read the session, it seems that it looks for the DLL of the first application, and when it can't find it, it throws an exception. Is there a flaw in my logic? Here's an example: // Global.asax of the 1st app protected void Session_Start(object sender, EventArgs e) { Session.Add( "UserSessionKey", new FirstUserSession()); // FirstUserSession inherits from BaseUserSession } Now the second application: // Global.asax of 2nd app protected void Session_Start(object sender, EventArgs e) { if (Session["UserSessionKey"] != null) { BaseUserSession existing = (BaseUserSession)Session["UserSessionKey"]; SecondUserSession session = new SecondUserSession(); // This also inherits from BaseUserSession session.Authenticated = existing.Authenticated; session.Id = existing.Id; session.Role = existing.Role; Session.Add("UserSessionKey", session); } else { Session.Add("UserSessionKey", new SecondUserSession()); } } Here's the exception stack trace. In this case, "MyCBC" is the real name of the first app, and "ASPTesting" is the second app. [SerializationException: Unable to find assembly 'MyCBC, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.] System.Runtime.Serialization.Formatters.Binary.BinaryAssemblyInfo.GetAssembly() +1871092 System.Runtime.Serialization.Formatters.Binary.ObjectReader.GetType(BinaryAssemblyInfo assemblyInfo, String name) +7545734 System.Runtime.Serialization.Formatters.Binary.ObjectMap..ctor(String objectName, String[] memberNames, BinaryTypeEnum[] binaryTypeEnumA, Object[] typeInformationA, Int32[] memberAssemIds, ObjectReader objectReader, Int32 objectId, BinaryAssemblyInfo assemblyInfo, SizedArray assemIdToAssemblyTable) +120 System.Runtime.Serialization.Formatters.Binary.ObjectMap.Create(String name, String[] memberNames, BinaryTypeEnum[] binaryTypeEnumA, Object[] typeInformationA, Int32[] memberAssemIds, ObjectReader objectReader, Int32 objectId, BinaryAssemblyInfo assemblyInfo, SizedArray assemIdToAssemblyTable) +52 System.Runtime.Serialization.Formatters.Binary.__BinaryParser.ReadObjectWithMapTyped(BinaryObjectWithMapTyped record) +190 System.Runtime.Serialization.Formatters.Binary.__BinaryParser.ReadObjectWithMapTyped(BinaryHeaderEnum binaryHeaderEnum) +61 System.Runtime.Serialization.Formatters.Binary.__BinaryParser.Run() +253 System.Runtime.Serialization.Formatters.Binary.ObjectReader.Deserialize(HeaderHandler handler, __BinaryParser serParser, Boolean fCheck, Boolean isCrossAppDomain, IMethodCallMessage methodCallMessage) +168 System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Deserialize(Stream serializationStream, HeaderHandler handler, Boolean fCheck, Boolean isCrossAppDomain, IMethodCallMessage methodCallMessage) +203 System.Web.Util.AltSerialization.ReadValueFromStream(BinaryReader reader) +788 System.Web.SessionState.SessionStateItemCollection.ReadValueFromStreamWithAssert() +55 System.Web.SessionState.SessionStateItemCollection.DeserializeItem(String name, Boolean check) +281 System.Web.SessionState.SessionStateItemCollection.get_Item(String name) +19 System.Web.SessionState.HttpSessionStateContainer.get_Item(String name) +13 System.Web.SessionState.HttpSessionState.get_Item(String name) +13 ASPTesting._Default.Page_Load(Object sender, EventArgs e) in C:\Documents and Settings\sarsstu\My Documents\Projects\Testing\ASPTesting\ASPTesting\Default.aspx.cs:20 System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) +14 System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) +35 System.Web.UI.Control.OnLoad(EventArgs e) +99 System.Web.UI.Control.LoadRecursive() +50 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +627 Thanks to everyone in advance.

  • NHibernate does not update entity when repository is passed by constructor

    - by Alex
    Hi everybody, I am developing with NHibernate for the first time in conjunction with ASP.NET MVC and StructureMap. The CodeCampServer serves as a great example for me. I really like the different concepts which were implemented there and I can learn a lot from it. In my controllers I use Constructur Dependency Injection to get an instance of the specific repository needed. My problem is: If I change an attribute of the customer the customer's data is not updated in the database, although Commit() is called on the transaction object (by a HttpModule). public class AccountsController : Controller { private readonly ICustomerRepository repository; public AccountsController(ICustomerRepository repository) { this.repository = repository; } public ActionResult Save(Customer customer) { Customer customerToUpdate = repository .GetById(customer.Id); customerToUpdate.GivenName = "test"; //<-- customer does not get updated in database return View(); } } On the other hand this is working: public class AccountsController : Controller { [LoadCurrentCustomer] public ActionResult Save(Customer customer) { customer.GivenName = "test"; //<-- Customer gets updated return View(); } } public class LoadCurrentCustomer : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { const string parameterName = "Customer"; if (filterContext.ActionParameters.ContainsKey(parameterName)) { if (filterContext.HttpContext.User.Identity.IsAuthenticated) { Customer CurrentCustomer = DependencyResolverFactory .GetDefault() .Resolve<IUserSession>() .GetCurrentUser(); filterContext.ActionParameters[parameterName] = CurrentCustomer; } } base.OnActionExecuting(filterContext); } } public class UserSession : IUserSession { private readonly ICustomerRepository repository; public UserSession(ICustomerRepository customerRepository) { repository = customerRepository; } public Customer GetCurrentUser() { var identity = HttpContext.Current.User.Identity; if (!identity.IsAuthenticated) { return null; } Customer customer = repository.GetByEmailAddress(identity.Name); return customer; } } I also tried to call update on the repository like the following code shows. But this leads to an NHibernateException which says "Illegal attempt to associate a collection with two open sessions". Actually there is only one. public ActionResult Save(Customer customer) { Customer customerToUpdate = repository .GetById(customer.Id); customer.GivenName = "test"; repository.Update(customerToUpdate); return View(); } Does somebody have an idea why the customer is not updated in the first example but is updated in the second example? Why does NHibernate say that there are two open sessions?

  • Object relationships

    - by Hammerstein
    This stems from a recent couple of posts I've made on events and memory management in general. I'm making a new question as I don't think the software I'm using has anything to do with the overall problem and I'm trying to understand a little more about how to properly manage things. This is ASP.NET. I've been trying to understand the needs for Dispose/Finalize over the past few days and believe that I've got to a stage where I'm pretty happy with when I should/shouldn't implement the Dispose/Finalize. 'If I have members that implement IDisposable, put explicit calls to their dispose in my dispose method' seems to be my understanding. So, now I'm thinking maybe my understanding of object lifetimes and what holds on to what is just wrong! Rather than come up with some sample code that I think will illustrate my point, I'm going to describe as best I can actual code and see if someone can talk me through it. So, I have a repository class, in it I have a DataContext that I create when the repository is created. I implement IDisposable, and when my calling object is done, I call Dispose on my repository and explicitly call DataContext.Dispose( ). Now, one of the methods of this class creates and returns a list of objects that's handed back to my front end. Front End - Controller - Repository - Controller - Front End. (Using Redgate Memory Profiler, I take a snapshot of my software when the page is first loaded). My front end creates a controller object on page load and then makes a request to the repository sending back a list of items. When the page is finished loading, I call Dispose on the controller which in turn calls dispose on the context. In my mind, that should mean that my connection is closed and that I have no instances of my controller class. If I then refresh the page, it jumps to two 'Live' instances of the controller class. If I look at the object retention graph, the objects I created in my call to the list are being held onto ultimately by what looks like Linq. The controller/repository aside, if I create a list of objects somewhere, or I create an object and return it somewhere, am I safe to just assume that .NET will eventually come and clean things up for me or is there a best practice? The 'Live' instances suggest to me that these are still in memory and active objects, the fact that RMP apparently forces GC doesn't mean anything?

  • Exception from Response.Redirect?

    - by allencoded
    I keep getting an error: A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll An exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll but was not handled in user code The thread '' (0x27ee4) has exited with code 0 (0x0).

The code above is the only C# code on my first asp page. That code relates to this code on this page. It is also the only C# code I have on my second page. I am simply just trying to pass a keyword from a search form to this block of code: if (Request.QueryString["Keywords"] != null){ string keywords = Request.QueryString["Keywords"]; string myAppID = "HIDDEN"; var xml = XDocument.Load("http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=findItemsByKeywords&SERVICE-VERSION=1.0.0&SECURITY-APPNAME=" + myAppID + "&RESPONSE-DATA-FORMAT=XML&REST-PAYLOAD&keywords=" + keywords + "&paginationInput.entriesPerPage=5"); XNamespace ns = "http://www.ebay.com/marketplace/search/v1/services"; var titles = from item in xml.Root.Descendants(ns + "title") select new{ title = xml.Descendants(ns + "title").Select (x => x.Value), }; foreach (var item in titles){ Label1.Text += item; } } This block of code calls the keyword value and uses it in an api to perform a search. The code of the xml(api) formats like this: <findItemsByKeywordsResponse xmlns="http://www.ebay.com/marketplace/search/v1/services"> <searchReslut count="5"> <item> <title></title> </item> <item> <title></title> </item> <item> <title></title> </item> Why am I getting this error how do you fix it?

  • Model binding broke after upgrade to Visual Studio 2010

    - by John
    I have an ASP.net MVC 1.0 VS2008 application that I just opened in Visual Studio 2010. When I did this Studio upgraded the app from VS2008 to the VS2010 project. It also upgraded the MVC references from 1.0 to 2.0. In my app I have a class for a form post, I then use the class for the model binding in the Action method so it will auto populate the values. This worked fine in mvc 1.0 but now it does not work in 2.0 after the upgrade. Does does anyone know why? Or where I should look to resolve this? Here is my class, public class Add_Postal_Form_Input { public string ACTION_RDO { get; set; } public string POSTALSELECT { get; set; } public string CNY_CD { get; set; } public string S_PST_LOW { get; set; } public string R_PST_LOW { get; set; } public string R_PST_HI { get; set; } public string G_PST_LOW { get; set; } public string G_GRP_CD { get; set; } public string CAT_CD { get; set; } public string SUB_CD { get; set; } public string ATTR_VAL { get; set; } public string NBG_HR { get; set; } public string NBG_MN { get; set; } public string REC_STT_DT { get; set; } public string REC_END_DT { get; set; } public string DEFAULT_DATE { get; set; } } Here is the method, [AcceptVerbs("POST")] public PartialViewResult AddData(Add_Postal_Form_Input FORM_IN) { Thanks

  • Session state has been disabled for ASP.NET.The Report Viewer control requires that session state be

    - by Patrick Olurotimi Ige
    While i was trying to setup some reports on a SPF 2010 site. After trying to add a Sql Reporting Webpart i get the error: Session state has been disabled for ASP.NET. The Report Viewer control requires that session state be enabled in local mode I never came across that error before when using RSWebaprts in Sharepoint 2007:) But i think is related to ASP.NET sessions state:( Any to fix it you would have to start to make sure the SharePoint Server ASP.NET Session State Service is enabled. Unfortunately in Sharepiint SPF2010 and SP 2010 you would have to do it using PowerShell By doing :  Enable-SPSessionStateService -Defaultprovision PS C:\> PSSnapin - Shows you all the PS Snapins PS C:\> Add-PSSnapin "Microsoft.SharePoint.PowerShell" -- Adds the Sharepoint PS Snapin PS C:\> get-command -Noun SP* -- Show all SP cmdlets PS C:\> Add-SPShellAdmin -- (If you get error regarding the access to the farm you use this command to add an acct to able to run the Shell admin) PS C:\> Get-Help Enable-SPSessionStateService - Shows helpp for  Enable-SPSessionStateService PS C:\> Enable-SPSessionStateService -Defaultprovision - (enables/activates SPSessionStateService) you have more oprions available when you run the Get-Help Enable-SPSessionStateService   After running the cmd you should see the SharePoint Server ASP.NET Session State Service started in your service applications in the Central Admin Site. And of course be able to add your RS webparts Enjoy

  • Validate if aTextBox Value Start with a Specific Letter

    - by Vincent Maverick Durano
    In case you will be working on a page that needs to validate the first character of the TextBox entered by a user then here are two options that you can use: Option 1: Using an array   1: <asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server"> 2: <script type="text/javascript"> 3: function CheckFirstChar(o) { 4: var arr = ['A', 'B', 'C', 'D']; 5: if (o.value.length > 0) { 6: for (var i = 0; i < arr.length; i++) { 7: if (o.value.charAt(0) == arr[i]) { 8: alert('Valid'); 9: return true; 10: } 11: else { 12: alert('InValid'); 13: return false; 14: } 15: } 16: } 17: } 18: </script> 19: </asp:Content> 20: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> 21: <asp:TextBox ID="TextBox1" runat="server" onblur="return CheckFirstChar(this);"></asp:TextBox> 22: </asp:Content>   The example above uses an array of string for storing the list of  characters that a TextBox value should start with. We then iterate to the array and compare the first character of TextBox value to see if it matches any characters from the array. Option 2: Using Regular Expression (Preferred way)   1: <asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server"> 2: <script type="text/javascript"> 3: function CheckFirstChar(o) { 4: pattern = /^(A|B|C|D)/; 5: if (!pattern.test(o.value)) { 6: alert('InValid'); 7: return false; 8: } else { 9: alert('Valid'); 10: return true; 11: } 12: } 13: </script> 14: </asp:Content> 15: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> 16: <asp:TextBox ID="TextBox1" runat="server" onblur="return CheckFirstChar(this);"></asp:TextBox> 17: </asp:Content>   The example above uses regular expression with the pattern  /^(A|B|C|D)/. This will check if the TextBox value starts with A,B,C or D. Please note that it's case sensitive. If you want to allow lower case then you can alter the patter to this /^(A|B|C|D)/i. The i in the last part will cause a case-insensitive search.   That's it! I hope someone find this post useful!

  • Installing a new ASP.NET 4.0 site on a Windows 2008 server.

    - by TATWORTH
    I have been specifically requested to blog about getting an ASP.NET 4.0 site working on a Windows 2008 server that has never run a 4.0 web site before. Make sure the 4.0 framework is installed on the server! Patch it will ALL the security patches have been applied. ((for a live server, make sure that you tested the patches on your development server first) You will find the HTTP Log status codes at http://support.microsoft.com/kb/943891 - they are very important in understandign the IIS logs) After installing, turn on 4.0, by doing the following: Start the Internet Information Services (IIS Manager) Select the server node in the connections pane. (this is the node above Application Pools, FTP Sites and Server Farms) Double click the ISAPI and CGI Restrictions item in the centre pane You should see 1 or 2 ASP.NET v4.0.30319 entries, select Enable in the Actions pane for all of them. ASP.NET 4.0 should now run! Remeber after creating your new 4.0 ASP.NET site. select the Sites node and find out the Id of it. By default, the IIS logs are at C:\inetpub\logs\LogFiles and if your site is say 21, then the logs will be created in the W3SVC21 sub-directory. The key point about using these logs is that in the event of an error when trying to start the site for the first time, the log will contain the status code and the sub-code. By having the full code and sub-code, set up issues can be resolved in minutes instead of hours.

  • Autocomplete jQuery on User Controller within Repeater .NET

    - by TheDPQ
    I have a Multiview search feature on a Web User Controller that is called within a Repeater, OHMY!! I have some training sessions being listed out on a page, each calling an employeeSearch Web User Controller so people can search for employees to add to the training session. I have the Employee Names and Employee IDs listed out in JS on the page and using the jQuery autocomplete i have them search for the employee and populate a hidden field in the User controller. Once the process is done they have the option of adding yet another employee. So i had Autocompelte 'work' in all the employee search boxes, but one i do the initial search (postback) autocomplete won't work again. Then i updated $().ready(function() to pageLoad() so it works correctly on multiple searches but only in the LAST item of the repeater (jQuery is loaded on the User Controller) FYI: I have the JS string set as EMPLOYEENAME|ID and jQuery displays the Employee Name and if they select it throws the ID in a ASP:HIDDEN FIELD <script type="text/javascript"> format_item = function(item, position, length) { var str = item.toString().split("|", 2); return str[0]; } function pageLoad() { $("#<%=tb_EmployeeName.ClientID %>").autocomplete(EmployeeList, { minChars: 0, width: 500, matchContains: true, autoFill: false, scrollHeight: 300, scroll: true, formatItem: format_item, formatMatch: format_item, formatResult: format_item }); $("#<%=tb_EmployeeName.ClientID %>").result(function(event, data, formatted) { var str = data.toString().split("|", 2); $("#<%=hf_EmployeeID.ClientID %>").val(str[1]); }); }; </script> I can already guess that by repeating pageLoad within the User Controll i override the previous pageLoad. THE QUESTION: Is there a way around this, a way to have all the jQuery appear in a single pageLoad or to somehow have a single jquery call to handle all my search boxes? I can't move the jQuery into the page calling all the controllers because i have no way of referencing the specific *tb_EmployeeName* textbox AND *hf_EmployeeID* hidden field. Thank you so much for any help or insight you can give me into this problem. This is the Multiview that on the User Controller <asp:MultiView ID="mv_EmployeeArea" runat="server" ActiveViewIndex="0"> <asp:View ID="vw_Search" runat="server"> <asp:Panel ID="eSearch" runat="server"> <b>Signup Employee Search</b> (<i>Last Name, First Name</i>)<br /> <asp:TextBox ID="tb_EmployeeName" class="EmployeeSearch" runat="server"></asp:TextBox> <asp:HiddenField ID="hf_EmployeeID" runat="server" /> <asp:Button ID="btn_Search" runat="server" Text="Search" /> </asp:Panel> </asp:View> <asp:View ID="vw_Confirm" runat="server"> <b>Signup Confirmation</b> <asp:FormView ID="fv_EmployeeInfo" runat="server"> <ItemTemplate> <%#(Eval("LastName"))%>, <%#(Eval("FirstName"))%><br /> </ItemTemplate> </asp:FormView> <asp:Button ID="btn_Confirm" runat="server" Text="Signup this employee" /> &nbsp; <asp:Button ID="btn_Reset3" runat="server" Text="Reset" /> </asp:View> <asp:View ID="vw_ThankYou" runat="server"> <b>Thank You</b><br /> The employee has been signed up and an email confirmation has been sent out.<br /><br /> <asp:Button ID="btn_Reset" runat="server" Text="Reset" /> </asp:View> </asp:MultiView> UPDATE: I never did find an answer but i had to do a demo so i hacked together something that 'works', but feels sort of cheesy. I am still very much needed of a better question or better understanding.

  • RedirectToAction help: or better suggestion

    - by Dean Lunz
    Still getting my feet wet with asp.net mvc. I have a working Action and httppost action but I want to replace the "iffy" code with a RedirectToAction call because the code is rather large for what it does. A call using RedirectToAction would clean it up more. Every way I've tried it fails to work for me in that the drop down list fails to have the proper item selected. The code below works fine but calling RedirectToAction the was I have been does not work for me. So how can i rework the code below to use RedirectToAction ? I find this line of code particularly troubling because there is no garentee that the "this.Url.RequestContext.RouteData.Route" property will be of type "System.Web.Routing.Route". // get url request var urlValue = "/" + ((System.Web.Routing.Route)(this.Url.RequestContext.RouteData.Route)).Url; I also find the second piece of code rather bloated ... // build the url template urlValue = urlValue.Replace("{realm}", realm); urlValue = urlValue.Replace("{guild}", guild); urlValue = urlValue.Replace("{date}", date.ToShortDateString().Replace("/", "-")); urlValue = urlValue.Replace("{pageIndex}", pageIndex.ToString()); urlValue = urlValue.Replace("{itemCount}", itemCountToDisplay.ToString()); The route I have setup is routes.MapRoute( "GuildOverview Realm", // Route name "GuildMembers/{realm}/{guild}/{date}/{pageIndex}/{itemCount}", // URL with parameters new { controller = "GuildMembers", action = "Index" }); // Parameter defaults The code for my controller actions is below ... [HttpPost] public ActionResult Index(string realm, string guild, DateTime date, int pageIndex, int itemCount, FormCollection formCollection) { // get form data if it's there and try parse num items to display var cnt = this.Request.Form["ddlDisplayCount"]; int itemCountToDisplay = 10; if (!string.IsNullOrEmpty(cnt)) int.TryParse(cnt, out itemCountToDisplay); // get url request var urlValue = "/" + ((System.Web.Routing.Route)(this.Url.RequestContext.RouteData.Route)).Url; // build the url template urlValue = urlValue.Replace("{realm}", realm); urlValue = urlValue.Replace("{guild}", guild); urlValue = urlValue.Replace("{date}", date.ToShortDateString().Replace("/", "-")); urlValue = urlValue.Replace("{pageIndex}", pageIndex.ToString()); urlValue = urlValue.Replace("{itemCount}", itemCountToDisplay.ToString()); return this.Redirect(urlValue); } public ActionResult Index(string realm, string guild, DateTime date, int pageIndex, int itemCount) { // get the page index ViewData["pageIndex"] = pageIndex; // validate item count var pageItemCountItems = new[] { 10, 20, 50, 100 }; if (!pageItemCountItems.Contains(itemCount)) itemCount = pageItemCountItems[0]; // calc the number of pages there are var numPages = (this._repository.GetGuildMemberCount(date, realm, guild) / itemCount) + 1; this.ViewData["pageCount"] = numPages; // get url request var urlValue = "/" + ((System.Web.Routing.Route)(this.Url.RequestContext.RouteData.Route)).Url; // build the url template urlValue = urlValue.Replace("{realm}", realm); urlValue = urlValue.Replace("{guild}", guild); urlValue = urlValue.Replace("{date}", date.ToShortDateString().Replace("/", "-")); urlValue = urlValue.Replace("{pageIndex}", "{0}"); urlValue = urlValue.Replace("{itemCount}", itemCount.ToString()); // set url template ViewData["UrlTemplate"] = urlValue; // set list of items for the display count dropdown var itemCounts = new SelectList(pageItemCountItems, itemCount); ViewData["DisplayCount"] = itemCounts; return View(_repository.GetGuildCharacters(date, realm, guild, (pageIndex - 1) * itemCount, itemCount)); } and my Index view contains the fallowing <%=Html.SimplePager(int.Parse(ViewData["pageIndex"].ToString()), int.Parse(ViewData["pageCount"].ToString()), ViewData["urlTemplate"].ToString(), "nav-menu")%> <% using (Html.BeginForm()) { %> <%= Html.DropDownList("ddlDisplayCount", (SelectList)ViewData["DisplayCount"], new { onchange = "this.form.submit();" })%> <% }%>

  • The model item passed into the dictionary is of type ‘mvc.Models.ModelA’ but this dictionary require

    - by Malcolm Frexner
    I have this annoying mistake in some of my builds. There is no error in the project, because if I build again, then the problem disappears. The message only appears, when the site is deployed to a Windows 2008 Server. I first thought that it might be an issue with temporary files, but thats not the case. I deployed the build to a different web and the error still appears. The error appears on random actions of the site. Most of the time builds are ok, but each 3rd or 4th build produces runtime errors. I build using a WebdeploymentProject in release mode. Views are precompiled. It's not http://stackoverflow.com/questions/178194/in-asp-net-mvc-i-encounter-an-incorrect-type-error-when-rendering-a-page-with-the, because views have totally different names.

  • Parse JSON in C#

    - by Ender
    I'm trying to parse some JSON data from the Google AJAX Search API. I have this URL and I'd like to break it down so that the results are displayed. I've currently written this code, but I'm pretty lost in regards of what to do next, although there are a number of examples out there with simplified JSON strings. Being new to C# and .NET in general I've struggled to get a genuine text output for my ASP.NET page so I've been recommended to give JSON.NET a try. Could anyone point me in the right direction to just simply writing some code that'll take in JSON from the Google AJAX Search API and print it out to the screen? EDIT: I think I've made some progress in regards to getting some code working using DataContractJsonSerializer. Here is the code I have so far. Any advice on whether this is close to working and/or how I would output my results in a clean format? EDIT 2: I've followed the advice from Dreas Grech and the StackOverflowException has gone. However, now I am getting no output. Any ideas on where to go next? EDIT 3: ALL FIXED! All results are working fine.

  • ELMAH - Filtering 404 Errors

    - by Nathan Taylor
    I am attempting to configure ELMAH to filter 404 errors and I am running into difficulties with the XML-provided filter rules in my Web.config file. I followed the tutorial here and here and added an <is-type binding="BaseException" type="System.IO.FileNotFoundException" /> declaration under my <test><or>... declaration, but that completely failed. When I tested it locally I stuck a breakpoint in protected void ErrorLog_Filtering() {} of the Global.asax found that the System.Web.HttpException that gets fired by ASP.NET for a 404 doesn't have a base type of System.IO.FileNotFound, but rather it is simply a System.Web.HttpException. Next I decided to try a <regex binding="BaseException.Message" pattern="The file '/[^']+' does not exist" /> in the hopes that any exception matching the pattern "The file '/foo.ext' does not exist" would get filtered, but that too having no effect. As a last resort I tried <is-type binding="BaseException" type="System.Exception" />, and even that is entirely disregarded. I'm inclined to think there's a configuration error with ELMAH, but I fail to see any. Am I missing something blatantly obvious? Here's the relevant stuff from my web.config: <configuration> <configSections> <sectionGroup name="elmah"> <section name="security" requirePermission="false" type="Elmah.SecuritySectionHandler, Elmah"/> <section name="errorLog" requirePermission="false" type="Elmah.ErrorLogSectionHandler, Elmah"/> <section name="errorMail" requirePermission="false" type="Elmah.ErrorMailSectionHandler, Elmah"/> <section name="errorFilter" requirePermission="false" type="Elmah.ErrorFilterSectionHandler, Elmah" /> </sectionGroup> </configSections> <elmah> <errorFilter> <test> <or> <equal binding="HttpStatusCode" value="404" type="Int32" /> <regex binding="BaseException.Message" pattern="The file '/[^']+' does not exist" /> </or> </test> </errorFilter> <errorLog type="Elmah.XmlFileErrorLog, Elmah" logPath="~/App_Data/logs/elmah" /> </elmah> <system.web> <httpModules> <add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah"/> <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/> </httpModules> </system.web> <system.webServer> <modules> <add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah"/> <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" /> </modules> </system.webServer> </configuration>

  • VS2010 Assembly Load Error

    - by Nate
    I am getting the following error when I try to build an ASP.NET 4 project in Visual Studio 2010: "Could not load file or assembly 'file:///C:\Dev\project\trunk\bin\Elmah.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)". I have verified that the dll does, in fact, exist, and is getting copied to the bin folder correctly. I have also tried removing and then re-adding the reference to the project. The build only fails when I switch the Solution Configuration to "Release". It does not fail when the Solution Configuration is set to "Debug". The only difference between the two configurations (that I know of) is shown in the following Web.config transform, Web.Release.config: <?xml version="1.0"?> <configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"> <connectionStrings> <add name="SqlServer" connectionString="" providerName="System.Data.SqlClient" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/> </connectionStrings> <system.web> <compilation xdt:Transform="RemoveAttributes(debug)" /> <customErrors mode="On" xdt:Transform="Replace"> <error statusCode="404" redirect="lost.htm" /> <error statusCode="500" redirect="uhoh.htm" /> </customErrors> </system.web> </configuration> I have tried using Fusion Log Viewer to track down the assembly binding issue, but it looks like it is finding and loading the assembly correctly.

  • nhibernate configure and buildsessionfactory time

    - by davidsleeps
    Hi, I'm using Nhibernate as the OR/M tool for an asp.net application and the startup performance is really frustrating. Part of the problem is definitely me in my lack of understanding but I've tried a fair bit (understanding is definitely improving) and am still getting nowhere. Currently ANTS profiler has that the Configure() takes 13-18 seconds and the BuildSessionFActory() as taking about 5 seconds. From what i've read, these times might actually be pretty good, but they were generally talking about hundreds upon hundreds of mapped entities...this project only has 10. I've combined all the mapping files into a single hbm mapping file and this did improve things but only down to the times mentioned above... I guess, are there any "Traps for young players" that are regularly missed...obvious "I did this/have you enabled that/exclude file x/mark file y as z" etc... I'll try the serialize the configuration thing to avoid the Configure() stage, but I feel that part shouldn't be that long for that amount of entities and so would essentially be hiding a current problem... I will post source code or configuration if necessary, but I'm not sure what to put in really... thanks heaps! edit (more info) I'll also add that once this is completed, each page is extremely quick... configuration code- hibernate.cfg.xml <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" /> </configSections> <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> <session-factory> <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property> <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property> <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property> <property name="connection.connection_string_name">MyAppDEV</property> <property name="cache.provider_class">NHibernate.Caches.SysCache.SysCacheProvider, NHibernate.Caches.SysCache</property> <property name="cache.use_second_level_cache">true</property> <property name="show_sql">false</property> <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property> <property name="current_session_context_class">managed_web</property> <mapping assembly="MyApp.Domain"/> </session-factory> </hibernate-configuration> </configuration> My SessionManager class which is bound and unbound in a HttpModule for each request Imports NHibernate Imports NHibernate.Cfg Public Class SessionManager Private ReadOnly _sessionFactory As ISessionFactory Public Shared ReadOnly Property SessionFactory() As ISessionFactory Get Return Instance._sessionFactory End Get End Property Private Function GetSessionFactory() As ISessionFactory Return _sessionFactory End Function Public Shared ReadOnly Property Instance() As SessionManager Get Return NestedSessionManager.theSessionManager End Get End Property Public Shared Function OpenSession() As ISession Return Instance.GetSessionFactory().OpenSession() End Function Public Shared ReadOnly Property CurrentSession() As ISession Get Return Instance.GetSessionFactory().GetCurrentSession() End Get End Property Private Sub New() Dim configuration As Configuration = New Configuration().Configure() _sessionFactory = configuration.BuildSessionFactory() End Sub Private Class NestedSessionManager Friend Shared ReadOnly theSessionManager As New SessionManager() End Class End Class edit 2 (log4net results) will post bits that have a portion of time between them and will cut out the rest... 2010-03-30 23:29:40,898 [4] INFO NHibernate.Cfg.Environment [(null)] - Using reflection optimizer 2010-03-30 23:29:42,481 [4] DEBUG NHibernate.Cfg.Configuration [(null)] - dialect=NHibernate.Dialect.MsSql2005Dialect ... 2010-03-30 23:29:42,501 [4] INFO NHibernate.Cfg.Configuration [(null)] - Mapping resource: MyApp.Domain.Mappings.hbm.xml 2010-03-30 23:29:43,342 [4] INFO NHibernate.Dialect.Dialect [(null)] - Using dialect: NHibernate.Dialect.MsSql2005Dialect 2010-03-30 23:29:50,462 [4] INFO NHibernate.Cfg.XmlHbmBinding.Binder [(null)] - Mapping class: ... 2010-03-30 23:29:51,353 [4] DEBUG NHibernate.Connection.DriverConnectionProvider [(null)] - Obtaining IDbConnection from Driver 2010-03-30 23:29:53,136 [4] DEBUG NHibernate.Connection.ConnectionProvider [(null)] - Closing connection

  • Ninject 2 and MVC 2.0

    - by theouteredge
    I've updated a project to VS2010 and MVC2 from VS2008 and MVC1. I'm having problems with Ninject not finding controllers within Areas Here is my global.asax.cs file: namespace Website { // Note: For instructions on enabling IIS6 or IIS7 classic mode, // visit http://go.microsoft.com/?LinkId=9394801 public class MvcApplication : NinjectHttpApplication { public static StandardKernel NinjectKernel; public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Balance", "Balance/{action}/{month}/{year}", new { controller = "Balance", action = "Index", month = DateTime.Now.Month, year = DateTime.Now.Year } ); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Login", action = "Index", id = "" } // Parameter defaults ); } /* protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); // initializes the NHProfiler so you can see what is going on with your queries HibernatingRhinos.Profiler.Appender.NHibernate.NHibernateProfiler.Initialize(); } */ protected override void OnApplicationStarted() { RegisterRoutes(RouteTable.Routes); AreaRegistration.RegisterAllAreas(); RegisterAllControllersIn(Assembly.GetExecutingAssembly()); } protected void Application_Error(object sender, EventArgs e) { var errorService = NinjectKernel.Get<IErrorLogService>(); errorService.LogError(HttpContext.Current.Server.GetLastError().GetBaseException(), "AppSite"); } protected override IKernel CreateKernel() { if (NinjectKernel == null) { NinjectKernel = new StandardKernel(new ServiceModule()); } return NinjectKernel; } } public class ServiceModule : NinjectModule { public override void Load() { Bind<IHelper>().To<Helper>().InRequestScope(); Bind<IErrorLogService>().To<ErrorLogService>(); Bind<INHSessionFactory>().To<NHSessionFactory>().InSingletonScope(); Bind<ISessionFactory>().ToMethod(ctx => ctx.Kernel.Get<INHSessionFactory>().GetSessionFactory()) .InSingletonScope(); Bind<INHSession>().To<NHSession>(); Bind<ISession>().ToMethod(ctx => ctx.Kernel.Get<INHSession>().GetSession()); } } } Accessing controllers within the /Controllers folder works OK, but accessing controllers within a /Areas/Member/Controller throws the following error: Server Error in '/' Application. Cannot be null Parameter name: service Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.ArgumentNullException: Cannot be null Parameter name: service Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. Stack Trace: [ArgumentNullException: Cannot be null Parameter name: service] Ninject.ResolutionExtensions.GetResolutionIterator(IResolutionRoot root, Type service, Func`2 constraint, IEnumerable`1 parameters, Boolean isOptional, Boolean isUnique) +193 Ninject.Web.Mvc.NinjectControllerFactory.GetControllerInstance(RequestContext requestContext, Type controllerType) +41 System.Web.Mvc.DefaultControllerFactory.CreateController(RequestContext requestContext, String controllerName) +66 System.Web.Mvc.MvcHandler.ProcessRequestInit(HttpContextBase httpContext, IController& controller, IControllerFactory& factory) +124 System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContextBase httpContext, AsyncCallback callback, Object state) +50 System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContext httpContext, AsyncCallback callback, Object state) +48 System.Web.Mvc.MvcHandler.System.Web.IHttpAsyncHandler.BeginProcessRequest(HttpContext context, AsyncCallback cb, Object extraData) +16 System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +8771488 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +184 Version Information: Microsoft .NET Framework Version:4.0.30128; ASP.NET Version:4.0.30128.1 The Url for this request is /Member/Controller/, If I change the Url too /Controller the controller fires but I get an error that the system cannot find the View in the path /Views When it should be looking in /Area/Members/Views I have either done something wrong in the upgrade or I'm missing something bt I just can't figure out what. I've been trying to figure this out for 3 days...
