  • Design question for WinForms (C#) app, using Entity Framework

    - by cdotlister
    I am planning on writing a small home budget application for myself, as a learning excercise. I have built my database (SQL Server), and written a small console application to interact with it, and test out scenarios on my database. Once I am happy, my next step would be to start building the application - but I am already wondering what the best/standard design would be. I am palnning on using Entity Framework for handling my database entities... then linq to sql/objects for getting the data, all running under a WinForms (for now) application. My plan (I've never used EF... and most of my development background is Web apps) is to have my database... with Entity Framework in it's own project.. which has the connection to the database. This project would expose methods such as 'GetAccount()', 'GetAccount(int accountId)' etc. I'd then have a service project that references my EF project. And on top of that, my GUI project, which makes the calls to my service project. But I am stuck. Lets say I have a screen that displays a list of Account types (Debit, Credit, Loan...). Once I have selected one, the next drop down shows a list of accounts I have that suite that account type. So, my OnChange event on my DropDown on the account type control will make a call to the serviceLayer project, 'GetAccountTypes()', and I would expect back a List< of Account Types. However, the AccountType object ... what is that? That can't be the AccountType object from my EF project, as my GUI project doesn't have reference to it. Would I have to have some sort of Shared Library, shared between my GUI and my Service project, with a custom built AccountType object? The GUI can then expect back a list of these. So my service layer would have a method: public List<AccountType> GetAccountTypes() That would then make a call to a custom method in my EF project, which would probably be the same as the above method, except, it returns an list of EF.Data.AccountType (The Entity Framework generated Account Type object). The method would then have the linq code to get the data as I want it. Then my service layer will get that object, and transform it unto my custom AccountType object, and return it to the GUI. Does that sound at all like a good plan?

  • ASP.NET MVC: How to allow some HTML mark-up in Html Encoded content?

    - by Dr. Zim
    Is there some magic existing code in MVC 2 to Html.Encode() strings and allow certain html markup, like paragraph marks and breaks? (coming from a Linq to SQL database field) A horrible code example to achieve the effect: Html.Encode(Model.fieldName).Replace("&lt;br /&gt;", "<br />") What would be really nice is to overload something and pass to it an array (or object) full of allowed html tags.

  • Validation framework for .NET Compact Framework 3.5.

    - by Michal Drozdowicz
    Do you know of a fast and simple entity validation framework that could be used in a Compact Framework project? I've done some experiments with FluentValidation (using db4o System.Linq.Expressions, but it's rather slow) and EViL (but it seems a bit half-baked). Can you suggest any other or maybe point me to some resources on how to design such a framework so that it's both easy to use and performant?

  • Common DataAnnotations in ASP.Net MVC2

    - by Scott Mayfield
    Howdy, I have what should be a simple question. I have a set of validations that use System.CompontentModel.DataAnnotations . I have some validations that are specific to certain view models, so I'm comfortable with having the validation code in the same file as my models (as in the default AccountModels.cs file that ships with MVC2). But I have some common validations that apply to several models as well (valid email address format for example). When I cut/paste that validation to the second model that needs it, of course I get a duplicate definition error because they're in the same namespace (projectName.Models). So I thought of removing the common validations to a separate class within the namespace, expecting that all of my view models would be able to access the validations from there. Unexpectedly, the validations are no longer accessible. I've verified that they are still in the same namespace, and they are all public. I wouldn't expect that I would have to have any specific reference to them (tried adding using statement for the same namespace, but that didn't resolve it, and via the add references dialog, a project can't reference itself (makes sense). So any idea why public validations that have simply been moved to another file in the same namespace aren't visible to my models? CommonValidations.cs using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel; using System.ComponentModel.DataAnnotations; using System.Text.RegularExpressions; namespace ProjectName.Models { public class CommonValidations { [AttributeUsage(AttributeTargets.Field | AttributeTargets.Property, AllowMultiple = true, Inherited = true)] public sealed class EmailFormatValidAttribute : ValidationAttribute { public override bool IsValid(object value) { if (value != null) { var expression = @"^[a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$"; return Regex.IsMatch(value.ToString(), expression); } else { return false; } } } } } And here's the code that I want to use the validation from: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel; using System.ComponentModel.DataAnnotations; using Growums.Models; namespace ProjectName.Models { public class PrivacyModel { [Required(ErrorMessage="Required")] [EmailFormatValid(ErrorMessage="Invalid Email")] public string Email { get; set; } } }

  • Using Include() with inherited entities problem

    - by Peter Stegnar
    In EF eager loading related entities is easy. But I'm having difficulties including inherited entities when loading data using table-per-type model. This is my model: Entities: ArticleBase (base article entity) ArticleSpecial (inherited from ArticleBase) UserBase (base user entity) UserSpecial (inherited from UserBase) Image Relations are as shown on the image (omitting many columns): In reality my users are always of type UserSpecial, since UserBase is used in another application, thus we can share credentials. That's the only reason I have two separate tables. UserBase table can't be changed in any way shape or form, because the other app would break. Question How am I suppose to load ArticleSpecial with both CreatedBy and EditedBy set, so that both are of type UserSpecial (that defines Image relation)? I've tried (unsuccessfully though) these options: 1. Using lambda expressions: context.ArticleBases .OfType<ArticleSpecial>() .Include("UserCreated.Image") .Include("UserEdited.Image"); In this case the problem is that both CreatedBy and EditedBy are related to UserBase, that doesn't define Image navigation. So I should somehow cast these two to UserSpecial type like: context.ArticleBases .OfType<ArticleSpecial>() .Include("UserCreated<UserSpecial>.Image") .Include("UserEdited<UserSpecial>.Image"); But of course using generics in Include("UserCreated<UserSpecial>.Image") don't work. 2. I have tried using LINQ query var results = from articleSpecial in ctx.ArticleBase.OfType<ArticleSpecial>() join created in ctx.UserBase.OfType<UserSpecial>().Include("Image") on articleSpecial.UserCreated.Id equals created.Id join edited in ctx.UserBase.OfType<UserSpecial>().Include("Image") on articleSpecial.UserEdited.Id equals edited.Id select articleSpecial; In this case I'm only getting ArticleSpecial object instances without related properties being set. I know I should select those somehow, but I don't know how? Select part in my LINQ could be changed to something like select new { articleSpecial, articleSpecial.UserCreated, articleSpecial.UserEdited }; but images are still not loaded into my context. My joins in this case are barely used to filter out articleSpecial results, but they don't load entities into context (I suppose). Can anybody provide any help regarding this problem? I think it's not so uncommon.

  • Built-in precedence in Expression Trees for math?

    - by jdk
    I'm unable to find the .NET FCL built-in concept of precedence to leverage while constructing Expression Trees. Ref System.Linq.Expressions Namespace. Is this something that must be handled manually in code, or is it somehow implicit and I'm not recognizing it (e.g. maybe through helper methods or classes)? I want to apply it to math operations to ensure 3 + 5 * 10 results in 53 instead of 80.

  • How can I switch between 2 Connection Strings in my Web.Config (Activate one for DBML)

    - by Alex
    Hello! I have two connection strings (both in Web.Config: CS_Local and CS_Production) for my DBML (Linq to SQL). In my Global.Asax/Application_Start I run some production preparation methods if the request is non-local (!HttpContext.Current.Request.IsLocal). Within that part, I'd also like to change the current connection string used by my DBML from the standard CS_Local to CS_Production. How would I do that? Some help please..

  • F# Equivalent to Enumerable.OfType<'a>

    - by Joel Mueller
    ...or, how do I filter a sequence of classes by the interfaces they implement? Let's say I have a sequence of objects that inherit from Foo, a seq<#Foo>. In other words, my sequence will contain one or more of four different subclasses of Foo. Each subclass implements a different independent interface that shares nothing with the interfaces implemented by the other subclasses. Now I need to filter this sequence down to only the items that implement a particular interface. The C# version is simple: void MergeFoosIntoList<T>(IEnumerable<Foo> allFoos, IList<T> dest) where T : class { foreach (var foo in allFoos) { var castFoo = foo as T; if (castFoo != null) { dest.Add(castFoo); } } } I could use LINQ from F#: let mergeFoosIntoList (foos:seq<#Foo>) (dest:IList<'a>) = System.Linq.Enumerable.OfType<'a>(foos) |> Seq.iter dest.Add However, I feel like there should be a more idiomatic way to accomplish it. I thought this would work... let mergeFoosIntoList (foos:seq<#Foo>) (dest:IList<'a>) = foos |> Seq.choose (function | :? 'a as x -> Some(x) | _ -> None) |> Seq.iter dest.Add However, the complier complains about :? 'a - telling me: This runtime coercion or type test from type 'b to 'a involves an indeterminate type based on information prior to this program point. Runtime type tests are not allowed on some types. Further type annotations are needed. I can't figure out what further type annotations to add. There's no relationship between the interface 'a and #Foo except that one or more subclasses of Foo implement that interface. Also, there's no relationship between the different interfaces that can be passed in as 'a except that they are all implemented by subclasses of Foo. I eagerly anticipate smacking myself in the head as soon as one of you kind people points out the obvious thing I've been missing.

  • What are the BEST resources for learning WPF & .NET?

    - by dicroce
    I'm a longtime C/C++ Unix guy. I recently started work in a new position that's gonna eventually require C# and WPF (and probably some LINQ). What are the best resources to quickly come up to speed on all these Microsoft technologies? Years ago I read Petzold's book and loved it because it was so complete and by the end I really felt like I knew what I was doing... Is their something equivalent for the .NET world?

  • How to add entity object to adequate entity set with object context in EF?

    - by Levelbit
    I have a problem when I add an entity object with ObjectContext.AddObject method because I can't retrieve that object with LINQ querying my ObjectContext.Person entities. I know that this new added object is stored somewhere, because it is used to update database after SaveChanges method. That's bothers me because I want to update my datagrid DataContext without saving changes unless I really want to do it. It doesn't help if I add the same object to DataContext list myself directly.

  • Lazy Loading wpf Combobox items

    - by Chris McGrath
    I have an IEnumerable< which lazy loads it's data. I want to just set a Combobox's ItemsSource to the IEnumerable, but when I do it goes and loads all the data anyway (which removes the point of lazy loading). I've tried it with Linq-To-Sql as well since it seems to be a similar theory and it also loads all the data. Is there an easy way to do this?

  • Advantage of creating a generic repository vs. specific repository for each object?

    - by LuckyLindy
    We are developing an ASP.NET MVC application, and are now building the repository/service classes. I'm wondering if there are any major advantages to creating a generic IRepository interface that all repositories implement, vs. each Repository having its own unique interface and set of methods. For example: a generic IRepository interface might look like (taken from this answer): public interface IRepository : IDisposable { T[] GetAll<T>(); T[] GetAll<T>(Expression<Func<T, bool>> filter); T GetSingle<T>(Expression<Func<T, bool>> filter); T GetSingle<T>(Expression<Func<T, bool>> filter, List<Expression<Func<T, object>>> subSelectors); void Delete<T>(T entity); void Add<T>(T entity); int SaveChanges(); DbTransaction BeginTransaction(); } Each Repository would implement this interface (e.g. CustomerRepository:IRepository, ProductRepository:IRepository, etc). The alternate that we've followed in prior projects would be: public interface IInvoiceRepository : IDisposable { EntityCollection<InvoiceEntity> GetAllInvoices(int accountId); EntityCollection<InvoiceEntity> GetAllInvoices(DateTime theDate); InvoiceEntity GetSingleInvoice(int id, bool doFetchRelated); InvoiceEntity GetSingleInvoice(DateTime invoiceDate, int accountId); //unique InvoiceEntity CreateInvoice(); InvoiceLineEntity CreateInvoiceLine(); void SaveChanges(InvoiceEntity); //handles inserts or updates void DeleteInvoice(InvoiceEntity); void DeleteInvoiceLine(InvoiceLineEntity); } In the second case, the expressions (LINQ or otherwise) would be entirely contained in the Repository implementation, whoever is implementing the service just needs to know which repository function to call. I guess I don't see the advantage of writing all the expression syntax in the service class and passing to the repository. Wouldn't this mean easy-to-messup LINQ code is being duplicated in many cases? For example, in our old invoicing system, we call InvoiceRepository.GetSingleInvoice(DateTime invoiceDate, int accountId) from a few different services (Customer, Invoice, Account, etc). That seems much cleaner than writing the following in multiple places: rep.GetSingle(x => x.AccountId = someId && x.InvoiceDate = someDate.Date); The only disadvantage I see to using the specific approach is that we could end up with many permutations of Get* functions, but this still seems preferable to pushing the expression logic up into the Service classes. What am I missing?

  • .NET JIT Code Cache leaking?

    - by pitchfork
    We have a server component written in .Net 3.5. It runs as service on a Windows Server 2008 Standard Edition. It works great but after some time (days) we notice massive slowdowns and an increased working set. We expected some kind of memory leak and used WinDBG/SOS to analyze dumps of the process. Unfortunately the GC Heap doesn’t show any leak but we noticed that the JIT code heap has grown from 8MB after the start to more than 1GB after a few days. We don’t use any dynamic code generation techniques by our own. We use Linq2SQL which is known for dynamic code generation but we don’t know if it can cause such a problem. The main question is if there is any technique to analyze the dump and check where all this Host Code Heap blocks that are shown in the WinDBG dumps come from? [Update] In the mean time we did some more analysis and had Linq2SQL as probable suspect, especially since we do not use precompiled queries. The following example program creates exactly the same behaviour where more and more Host Code Heap blocks are created over time. using System; using System.Linq; using System.Threading; namespace LinqStressTest { class Program { static void Main(string[] args) { for (int i = 0; i < 100; ++ i) ThreadPool.QueueUserWorkItem(Worker); while(runs < 1000000) { Thread.Sleep(5000); } } static void Worker(object state) { for (int i = 0; i < 50; ++i) { using (var ctx = new DataClasses1DataContext()) { long id = rnd.Next(); var x = ctx.AccountNucleusInfos.Where(an => an.Account.SimPlayers.First().Id == id).SingleOrDefault(); } } var localruns = Interlocked.Add(ref runs, 1); System.Console.WriteLine("Action: " + localruns); ThreadPool.QueueUserWorkItem(Worker); } static Random rnd = new Random(); static long runs = 0; } } When we replace the Linq query with a precompiled one, the problem seems to disappear.
