  • Custom Validation with MVC2 and EF4

    - by csharpnoob
    Hi, on ScottGu's Blog is an Example how to use MVC2 Custom Validation with EF4: http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx So here the Problem: When the Designer in VS2010 creates the Objects for the DB, along to the example you have to add [MetadataType(typeof(Person_validation))] Annotation to that class. But when i change anything in the Designer all these Annotations are lost. Is it possible to keep self made changes to the edmx file, or is there any better way of applying System.ComponentModel.DataAnnotations to the generated Entities? Thanks.

  • problem when view the super block in ext3 file system

    - by xuczhang
    I tried to view the superblock by command "dd" in ext3 file system. dd if=/dev/sda3 bs=4096 skip=1 count=1 of=superblock But the result in superblock file is not correct(I compare the value of Inodes count I got from dumpe2fs). The device file /dev/sda3 is started at the boot block and then the superblock of the group0? And another question is the boot block and superblock's size are both BLOCKSIZE(here is 4096)? The disk format of ext2/ext3(I think they are the same) are shown below:

  • How to display and update data in MVC2

    - by Picflight
    Table Product Product Id Product Name Table ProductSupplier ProductSupplierId ProductId SupplierId Table Supplier SupplierId SupplierName I have the above 3 tables in my database, ProductSupplier is the lookup table. Each Product can have many suppliers. I am using Entity Framework. Using Web Forms it was fairly easy to display a Product on a web page and bind a repeater with the suppliers information. Also, with Web Forms it was easy to Add new Product and suppliers, the linkage seemed easy. How do you do this sort of functionality in MVC? In the Create View below, I want to be able to Add the Supplier as well. Is there a better approach that I might be missing here? This is how I did it with Web Forms. Beyond the code below I am totally lost. I can show data in a list and also display the Suppliers for each Product, but how do I Add and Edit. Should I break it into different views? With Web Forms I could do it all in one page. namespace MyProject.Mvc.Models { [MetadataType(typeof(ProductMetaData))] public partial class Product { public Product() { // Initialize Product this.CreateDate = System.DateTime.Now; } } public class ProductMetaData { [Required(ErrorMessage = "Product name is required")] [StringLength(50, ErrorMessage = "Product name must be under 50 characters")] public object ProductName { get; set; } [Required(ErrorMessage = "Description is required")] public object Description { get; set; } } public class ProductFormViewModel { public Product Product { get; private set; } public IEnumerable<ProductSupplier> ProductSupplier { get; private set; } public ProductFormViewModel() { Product = new Product(); } public ProductFormViewModel(Product product) { Product = product; ProductSupplier = product.ProductSupplier; } } } ProductRepository public Product GetProduct(int id) { var p = db.Product.FirstOrDefault(por => por.ProductId == id); p.ProductSupplier.Attach(p.ProductSupplier.CreateSourceQuery().Include("Product").ToList()); return p; } Product Create View <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MyProject.Mvc.Models.ProductFormViewModel>" %> <%= Html.ValidationSummary("Please correct the errors and try again.") %> <% using (Html.BeginForm()) {%> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.Product.ProductId) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.ProductId) %> <%= Html.ValidationMessageFor(model => model.Product.ProductId) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Product.ProductName) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.ProductName) %> <%= Html.ValidationMessageFor(model => model.Product.ProductName) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Product.Description) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.Description) %> <%= Html.ValidationMessageFor(model => model.Product.Description) %> </div> <p> <input type="submit" value="Create" /> </p> </fieldset> <% } %>

    I'd like to start a collection of good, free cheat sheet resources for system administrators. Please add your favorite ones. From the Wikipedia "cheat sheet" article: In more general usage, a "cheat sheet" is any short (one or two page) reference to terms, commands, or symbols where the user is expected to understand the use of such terms etc but not necessarily to have memorized all of them.

  • How do I disable location services system wide?

    - by Daisetsu
    Google has an API which can determine someone's location based on the wifi router names which a user's computer can see. You will see this if you go to google maps and your browser may ask if you would like to share location data. I am wondering if there is any way to disable this on a system wide setting rather than just in each browser (Chrome can do this too). Is there any way I can limit which applications have a list of the wireless routers I can see?

  • Need a good mp3/internet radio organization system...

    - by Zombies
    So I feel that winamp alone doesn't work well for me. I have this one playlist that all kinds of stuff gets crammed into. I need a system (this can easily be 1 program or several): Need to be able to... play mp3's from my library (just a directory structure with mp3's). Save radio station's, and easily remove/add new stations play random mp3's which are not part of my library and will probably be deleted in the future, yet won't clutter my library index!

  • iPhone Development - Query related records using CoreData

    - by Mustafa
    I have a case where i have three entities with one-to-many and one-to-many relationships: Entity A (Entity B relationhip), Entity B (Entity A relationship, Entity C relationship), Entity C (Entity B relationhip) I have the reference of Entity A, and now i want to fetch all the related Entity C records. How can i do that? (with least amount of code) Edit: Here's another way to put it. Can we perform joins with CoreData. For example, (and this is a very crude example), We have a following entity-relationship: Grand Parent (1)---(m) Parent Parent (1)---(m) Child So, now if i have "Albert" the Grand Parent, and i want to get all his grand children, how can i do that?

  • SecurityException in Sandboxed AppDomain

    - by Galen
    I'm attempting to use C# as a scripting language using CSharpCodeProvider (using VS2010 and .NET 4.0). I want the scripts to be run in a restricted AppDomain with minimal permissions. Currently, I'm getting an exception while trying to instantiate a class in the AppDomain (The call to CreateInstanceAndUnwrap()).

  • Windows DFS File System Clustering

    - by tearman
    We're attempted to set up a high availability network for our file servers, and we're wanting to do a DFS file system cluster using the same back-end storage (our back-end storage has its own clustering mechanisms that it manages itself). The question being, A. how would one go about setting up DFS clustering, and B. how can we get Windows to cooperate with multiple servers accessing the same SAN volumes?
