  • MVC route with id and sub-action

    - by Dan Revell
    I can't figure out what I need to do with MVC routing to make this work Here's my one route: routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "{controller}/{id}/{action}", defaults: new { id = RouteParameter.Optional, action = RouteParameter.Optional } ); The request /Shipments/ works great. The request /Shipments/3/Packages works great. The request /Shipments/3 however fails with the error: Multiple actions were found that match the request: System.Linq.IQueryable`1[Api.Controllers.RequisitionsController+PackageRequisitionWithTracking] GetPackageRequisitions(Int32) on type Api.Controllers.RequisitionsController Api.Models.ShipmentRequisition GetShipmentRequisitions(Int32) on type Api.Controllers.RequisitionsController It can't seem to differentiate between: public ShipmentRequisition GetShipmentRequisitions(int id) and [ActionName("Packages")] public IQueryable<PackageRequisitionWithTracking> GetPackageRequisitions(int id) I would have thought the lack of action name on the get shipment by id would allow that route to work.

    - by Richmond
    Hi All! I have asp.net application, using LINQ to connecto to SQL Server 2008 R2 databse. My connection string: Data Source=[SqlServerIp];Initial Catalog=[databaseName]User Id=newLogin;Password=newPassword; When I deploy application on my local IIS (which is not the same machine as database server) it works fine, but when I deploy application on other IIS (the same machine as sqlServer) it throws an exception: System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. Anyone knows how to fix it? Maybe it is due to some bad configuration of IIS? Please help.

    - by MigNix
    Hi, I know this can look like dublicate of other discussions and I have already reviewed them, but they are different. I want to learn Java and I want to know are there any books similar to those that I have seen for C#. Here is the list: C# 4.0 in a Nutshell: The Definitive Reference Probably Java in a Nutshell :) Professional C# 4.0 and .NET 4 Pro C# 2010 and the .NET 4 Platform Accelerated C# 2010 Programming WCF Services Essential Windows Communication Foundation (WCF): For .NET Framework 3.5 C# in Depth: What you need to master C# 2 and 3 CLR via C# Professional ADO.NET 3.5 with LINQ and the Entity Framework Professional Enterprise .NET Framework Design Guidelines: Conventions, Idioms, and Patterns for Reusable .NET Libraries Mainly I am interested in Java 6 and want to know about JVM , Cuncurency, Data access and distributed application technologies. I have seen there are some books on JVM like Inside the Java 2 Virtual Machine also some free books on official web site. Also I found concurrent programming in Java. But may be you can suggest any others. Thank you

  • Better understanding of my SQL transactions

    - by Slew Poke
    I just realized that my application was needlessly making 50+ database calls per user request due to some hidden coding -- hidden in the sense that between LINQ, persistence frameworks and events it just so turned out that a huge number of calls were being made without me being aware. Is there a recommended way to analyze individual transactions going to my SQL 2008 database, preferably with some integration to my Visual Studio 2010 environment? I want to be able to 'spy' on individual transactions being made, but only for certain pieces of my code, and without making serious changes to either the code or database.

  • Static constructor can run after the non-static constructor. Is this a compiler bug?

    - by Joe H
    The output from the following program is: Non-Static Static Non-Static Is this a compiler bug? I expected: Static Non-Static Non-Static because I thought the static constructor was ALWAYS called before the non-static constructor. I tested this with Visual Studio 2010 using both .net 3.5 and .net 4.0. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace StaticConstructorBug { class Program { static void Main(string[] args) { var mc = new MyClass(); Console.ReadKey(); } } public class MyClass { public MyClass() { Console.WriteLine("Non-static"); } static MyClass() { Console.WriteLine("Static"); } public static MyClass aVar = new MyClass(); } }

  • Does MVC replace traditional manually created BLL?

    - by used2could
    I'm used to creating the UI, BLL, DAL by hand (some times I've used LINQ-to-SQL or SubSonic for the DAL). I've done several small projects using MVC since its release. On these projects I've still continued to write a BLL and DAL by hand and then incorporate those into the MVC's models/controllers. I'm looking to optimize my time on projects this seems like overkill and a potential waste of time. Question Would it be acceptable to roll a DAL such as SubSonic and directly use it in the Models/Controllers of my MVC web app? Now the models & controllers would act as the BLL. I just see this as a major timesaver to not have to worry about another tier. UPDATE: I just wanted to add that my concern isn't really with the DAL (I frequently use SubSonic and NH) but rather focus on the BLL. Sorry for the confusion.

  • How should I generate HTML to represent class and its properties?

    - by Mike
    Currently I have a class that represents a document. This document needs to be displayed as HTML. I would like to have a method to call such as GetHTML() that would then call GetHTML() on any properties/sections of the document that needed to be rendered. I was initially thinking about using linq and XElement but am wondering if that may cause issues with certain tags in HTML. Would I better off using an HtmlTextWriter? I am open to any suggestions or best practives for this situation. Thanks!

  • Can't update rows in my database using Entity Framework...?

    - by Dissonant
    Okay, this is really weird. I made a simple database with a single table, Customer, which has a single column, Name. From the database I auto-generated an ADO.NET Entity Data Model, and I'm trying to add a new Customer to it like so: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Test { class Program { static void Main() { Database1Entities db = new Database1Entities(); Customer c = new Customer(); c.Name = "Harry"; db.AddToCustomer(c); db.SaveChanges(); } } } But it doesn't persist Customer "Harry" to the database! I've been scratching my head for a while now wondering why such a simple operation doesn't work. What on earth could be the problem!?

  • Which .NET data provider?

    - by worlds-apart89
    I am new to database programming, so I'd like help getting on the right track. I have read that there are Microsoft-defined and third-party data providers for data access. MSDN has information on data providers for SQL Server, OLE DB, ODBC, Oracle, as well as the EntityClient provider (Entity Framework). Which data provider is today's hottest, most-widely used model? Which one is the future? Also, I have seen Linq to SQL tutorials, but what category does L2S fall into?

  • Show data relationship in gridview with dropdownlist or similar?

    - by Anders Svensson
    I have data coming from two tables with a foreign key relationship - one User table containing users of the web application, and one Page table containing details about pages visited by each user. I would like to be able to view these data in a gridview or the like on a page. It's easy enough to just show the User table data like so (I'm using the Entity Framework and LINQ): UserDBEntities context = new UserDBEntities(); GridView1.DataSource = from user in context.UserSet select new { user.Ip, user.Count, user.Description, user.Referer }; GridView1.DataBind(); But how can I show the Page details? I'm not bent on any particular way of showing it, but the only idea I've been able to come up with is to have a dropdown list for each user in a column. But I can't figure out how to get the page data into such a dropdown list. The tables are associated with the primary/foreign key UserID. Any ideas would be welcome (dropdownlist solution or other)!

  • Update database using restful ASP.NET MVC 1.0

    - by Mike
    We are building an MVC 1.0 application right now and using Linq - SQL for our DAL. Following the restful approach we have multiple action events depending on if you are updating or loading or what not. The two that I'm concerned with at this point are the edit and update action methods. Here is the signatures. public ActionResult Update(int customerId, int Id, AggregateModel viewModel) public ActionResult Edit(int customerId, int Id, AggregateModel viewModel) So the idea is that in the Edit method we load up our viewModel and pass it to the view. The user makes changes to the model and then posts back to the Update method. The first thing I could think of to do would be to get the viewModel from the database again, copy the changes in one by one from the posted back model and then submit it back. This would work but does seem clunky to me. What is the best way to insert those changes into the database at this point?

  • ASP.Net layered communication

    - by Chris Klepeis
    Hi, We're developing a layered web application. The specs: 3 layers, data layer, business layer, ui layer. Programmed in C# Data Layer uses the entity framework Currently we plan on having the data layer return IEnumerable<T> to the business layer via linq 2 entities, and the business layer will return data to the ui layer. Since the ui layer has no knowledge of the existance of the data layer, how would it handle a result of IEnumerable passed to it from the BLL, where T is defined in the data layer? Are there any GOOD example out there on how to do this. Please note that I'm extremely new to factories / interfaces / abstraction to loosely couple layers. I saw the question here http://stackoverflow.com/questions/917457/passing-data-in-an-ntier-application and it was recommended to have the entity layer shared amongst all layers... however I do not want the other layers to be able to query the database.

  • Missing type or namespace name

    - by Psytronic
    This is an odd one, not one I've come across before. My project complies and runs fine if I have my classes in the root folder (Not in App_Code). As soon as I move them into the App_Code folder then it will compile, but running it will bring up the old CS0234: The type or namespace name 'Linq' does not exist in the namespace 'System.Data' (are you missing an assembly reference?) I don't understand how moving the class(es) to the App_Code folder causes the whole thing to fall apart there? Project target is .Net 4 on VWD 2010 Express

  • In few words, what can be said about Func<>

    - by Richard77
    Hello, I've been seing Func< for sometime now, and I've manage to avoid it (for now). But, now it looks like I can't dodge it forever. For instance, I tried Dynamic Linq, but almost everything was in terms of Func<. I've tried one of my book (C# 2008/Deitel&Deitel) and also MSDN but I'm not getting it yet. They all jump straight in the subject. What can be said (in few words) about Func< Can I get some links on the web that can get me started on that matter? Thanks for helping

  • Where to find .NET version usage statistics?

    - by Mash
    There are some technologies like LINQ and WPF which are nice, but installation of .NET 3.5 is still slow procedure. It's important to understand - among Windows users how many of them have .NET 3.5 installed? Is there any good up to date stats gathered about .NET Version availability/usage? I've searched a lot, but can't find. Update: .NET version IS present in web-agent strings for FF and IE at least. So there SHOULD be somebody who have that information. Anyone with access to really large web-site logs? Update 2: I also understand Vista means that user have 3.5, but XP is still dominating the market.

  • Is there an easier way to reconcile a list of files and a directory with subfolders/files to find ch

    - by rwmnau
    I have a SQL Server table with a list of files (path + filename), and a folder with multiple layers and files in each layer. I'm looking for a way to reconcile the two without having to process the list twice. Currently, I'm doing this: For Each f as FileInfo In FileListFromDatabase If f.Exists is False, mark it as deleted in the database Next For Each f as FileInfo In RecursiveListOFFilesOnDisk If Not FileExistsInDatabase, then add it Next Is there a better way to do this? I'd like to avoid converting all the matching files (of which most will be) to FileInfo objects twice. Since I'm a T-SQL developer first, I'm picturing something like an OUTER JOIN of the two lists where they don't match. Something LINQ-ish?

  • Input Sanitation Best Practices

    - by Adam Driscoll
    Our team has recently been working on a logic and data layer for our database. We were not approved to utilize Entity or Linq to SQL for the data layer. It was primarily built by hand. A lot of the SQL is auto generated. An obvious down fall of this is the need to sanitize inputs prior to retrieval and insertion. What are the best methods for doing this? Searching for terms like insert, delete, etc seems like a poor way to accomplish this. Is there a better alternative?

  • Using ExecuteQuery() with entity framework, entity class.

    - by sfreelander
    I am trying to jump from ASP Classic to asp.net. I have followed tutorials to get Entity Framework and LINQ to connect to my test database, but I am having difficulties figuring out ExecuteQuery(). I believe the problem is that I need an "entity class" for my database, but I can't figure out how to do it. Here is my simple code: Dim db as New TestModel.TestEntity Dim results AS IEnumerable(OF ???) = db.ExecuteQuery(Of ???)("Select * from Table1") From the microsoft example site, they use an entity class called Customers, but I don't understand what that means.
