  • Partial view is not rendering within the main view it's contained (instead it's rendered in it's own page)?

    - by JaJ
    I have a partial view that is contained in a simple index view. When I try to add a new object to my model and update my partial view to display that new object along with existing objects the partial view is rendered outside the page that it's contained? I'm using AJAX to update the partial view but what is wrong with the following code? Model: public class Product { public int ID { get; set; } public string Name { get; set; } [DataType(DataType.Currency)] public decimal Price { get; set; } } public class BoringStoreContext { List<Product> results = new List<Product>(); public BoringStoreContext() { Products = new List<Product>(); Products.Add(new Product() { ID = 1, Name = "Sure", Price = (decimal)(1.10) }); Products.Add(new Product() { ID = 2, Name = "Sure2", Price = (decimal)(2.10) }); } public List<Product> Products {get; set;} } public class ProductIndexViewModel { public Product NewProduct { get; set; } public IEnumerable<Product> Products { get; set; } } Index.cshtml View: @model AjaxPartialPageUpdates.Models.ProductIndexViewModel @using (Ajax.BeginForm("Index_AddItem", new AjaxOptions { UpdateTargetId = "productList" })) { <div> @Html.LabelFor(model => model.NewProduct.Name) @Html.EditorFor(model => model.NewProduct.Name) </div> <div> @Html.LabelFor(model => model.NewProduct.Price) @Html.EditorFor(model => model.NewProduct.Price) </div> <div> <input type="submit" value="Add Product" /> </div> } <div id='productList'> @{ Html.RenderPartial("ProductListControl", Model.Products); } </div> ProductListControl.cshtml Partial View @model IEnumerable<AjaxPartialPageUpdates.Models.Product> <table> <!-- Render the table headers. --> <tr> <th>Name</th> <th>Price</th> </tr> <!-- Render the name and price of each product. --> @foreach (var item in Model) { <tr> <td>@Html.DisplayFor(model => item.Name)</td> <td>@Html.DisplayFor(model => item.Price)</td> </tr> } </table> Controller: public class HomeController : Controller { public ActionResult Index() { BoringStoreContext db = new BoringStoreContext(); ProductIndexViewModel viewModel = new ProductIndexViewModel { NewProduct = new Product(), Products = db.Products }; return View(viewModel); } public ActionResult Index_AddItem(ProductIndexViewModel viewModel) { BoringStoreContext db = new BoringStoreContext(); db.Products.Add(viewModel.NewProduct); return PartialView("ProductListControl", db.Products); } }

  • How can I write javaScript cookies to keep the data persistent after page reloads on my form?

    - by Johhny Thero
    Hello, I am trying to learn how to write cookies to keep the data in my CookieButton1 button persistent and to survive refreshes and page reloads. How can I do this in JavaScript? I have supplied my source code. Any advise, links or tutorials will be very helpful. If you navigate to http://iqlusion.net/test.html and click on Empty1, it will start to ask you questions. When finished it stores everything into CookieButton1. But when I refresh my browser the data resets and goes away. Thanks! <html> <head> <title>no_cookies> </head> <script type="text/javascript" > var Can1Set = "false"; function Can1() { if (Can1Set == "false") { Can1Title = prompt("What do you want to name this new canned response?",""); Can1State = prompt("Enter a ticket state (open or closed)","closed"); Can1Response = prompt("Enter the canned response:",""); Can1Points = prompt("What point percentage do you want to assign? (0-10)","2.5"); // Set the "Empty 1" button text to the new name the user specified document.CookieTest.CookieButton1.value = Can1Title; // Set the cookie here, and then set the Can1Set variable to true document.CookieTest.CookieButton1 = "CookieButton1"; Can1Set = true; }else{ document.TestForm.TestStateDropDownBox.value = Can1State; document.TestForm.TestPointsDropDownBox.value = Can1Points; document.TestForm.TestTextArea.value = Can1Response; // document.TestForm.submit(); } } </script> <form name=TestForm> State: <select name=TestStateDropDownBox> <option value=new selected>New</option> <option value=open selected>Open</option> <option value=closed>Closed</option> </select> Points: <select name=TestPointsDropDownBox> <option value=1>1</option> <option value=1.5>1.5</option> <option value=2>2</option> <option value=2.5>2.5</option> <option value=3>3</option> <option value=3.5>3.5</option> <option value=4>4</option> <option value=4.5>4.5</option> <option value=5>5</option> <option value=5.5>5.5</option> <option value=6>6</option> <option value=6.5>6.5</option> <option value=7>7</option> <option value=7.5>7.5</option> <option value=8>8</option> <option value=8.5>8.5</option> <option value=9>9</option> <option value=9.5>9.5</option> <option value=10>10</option> </select> <p> Ticket information:<br> <textarea name=TestTextArea cols=50 rows=7></textarea> </form> <form name=CookieTest> <input type=button name=CookieButton1 value="Empty 1" onClick="javascript:Can1()"> </form>

  • Loading any MVC page fails with the error "An item with the same key has already been added."

    - by MajorRefactoring
    I am having an intermittent issue that is appearing on one server only, and is causing all MVC pages to fail to load with the error "An item with the same key has already been added." Restarting the application pool fixes the issue, but until then, loading any mvc page throws the following exception: Event code: 3005 Event message: An unhandled exception has occurred.

  • jqGrid - Problems opening in jquery tabs (on Firefox and Google Chrome)

    - by Ben Hargreaves
    I have developed a very simple MVC app to test out trirand's jqGrid for MVC. The app opens a jqgrid in a jquery tab group and everything is ok with IE. However when I use Firefox jqgrid only opens occasionaly in the first tab (but not under any other tab), and in Chrome my jqgrids dont appear to open under any tab of the group. I'm a bit of an MVC newbie (and have only been testing jqgrid out for a few days), but I know my users will want to use different browsers. Trirand have not come back with any answer so wondered if anyone else had had a similar issue. I have really just implemented jqgrid as per the controllers and model in the sample application on the Trirand site, and then combined it with a straightforward jquery tab group. My MVC Details Page is as follows; <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<PRAMSAPP.Models.Family>" %> <%@ Import Namespace="Trirand.Web.Mvc" %> <%@ Import Namespace="PRAMSAPP.Controllers" %> <%@ Import Namespace="PRAMSAPP.Models" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Details </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link rel="stylesheet" type="text/css" href="/scripts/jquery-ui-1.7.2.custom.css" /> <script type="text/javascript" src="/scripts/jquery-1.3.2.min.js"></script> <script type="text/javascript" src="/scripts/jquery-ui-1.7.2.custom.min.js"></script> <fieldset> <legend>Family</legend> <div class="display-field"><%= Html.Encode(Model.FamilyID) %></div> <div class="display-field"><%= Html.Encode(Model.FamilySurname) %></div> </fieldset> <div id="tabs"> <ul> <li> <%= Html.ActionLink("GridChildren", "GridDemo", new { controller = "Grid", id = Model.FamilyID })%> </li> <li> <%= Html.ActionLink("Children", "ShowFamiliesChildren", new { famid = Model.FamilyID, page = Page})%> </li> </ul> </div> <p> <%= Html.ActionLink("Edit", "Edit", new { id=Model.FamilyID }) %> | <%= Html.ActionLink("Back to List", "Index") %> </p> <script type="text/javascript"> $(function() { $('#tabs').tabs(); }); </script> </asp:Content> And My Controller page is as follows; <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<PRAMSAPP.Models.FamiliesChildrenJqGridModel>" %> <%@ Import Namespace="Trirand.Web.Mvc" %> <%@ Import Namespace="PRAMSAPP.Controllers" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head id="Head1" runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <!-- The jQuery UI theme that will be used by the grid --> <link rel="stylesheet" type="text/css" media="screen" href="/Content/themes/redmond/jquery-ui-1.7.1.custom.css" /> <!-- The Css UI theme extension of jqGrid --> <link rel="stylesheet" type="text/css" media="screen" href="/Content/themes/ui.jqgrid.css" /> <!-- jQuery library is a prerequisite for jqGrid --> <script type="text/javascript" src="/Scripts/jquery-1.3.2.min.js"></script> <!-- language pack - MUST be included before the jqGrid javascript --> <script type="text/javascript" src="/Scripts/grid.locale-en.js"></script> <script type="text/javascript" src="/Scripts/jqgrid/jquery.jqGrid.min.js"></script> </head> <body> <div> <%= Html.Trirand().JQGrid(Model.FamiliesChildrenGrid, "JQGrid1") %> </div> </body>

  • Inheritance security rules violated while overriding member - SecurityRuleSet.Level2

    - by Page Brooks
    I have a class that inherits from Exception. In .NET 4, I started receiving a runtime error: Inheritance security rules violated while overriding member: MyBusinessException.GetObjectData(System.Runtime.Serialization.SerializationInfo, System.Runtime.Serialization.StreamingContext)'. Security accessibility of the overriding method must match the security accessibility of the method being overriden. I think the issue is caused by the fact that I am overriding GetObjectData. I know one answer for resolving the issue is to set the SecurityRuleSet: [assembly: SecurityRules(SecurityRuleSet.Level1)] This is not an acceptable answer, I'd like to know how to fix the issue without having to relax the default security rules in .NET 4.

  • Non-blocking read on a stream in python.

    - by Mathieu Pagé
    Hi, I'm using the subprocess module to start a subprocess and connect to it's output stream (stdout). I want to be able to execute non-blocking reads on its stdout. Is there a way to make .readline non-bloking or to check if there is data on the stream before I invoke .readline? I'd like this to be portable or at least work under Windows and Linux. here is how I do it for now (It's blocking on the .readline if no data is avaible): p = subprocess.Popen('myprogram.exe', stdout = subprocess.PIPE) str = p.stdout.readline() Thanks for your help.

  • jQuery Treeview – Expand and Collapse All Without the TreeControl

    - by Ben Griswold
    The jQuery Treeview Plugin provides collapse all, expand all and toggle all support with very little effort on your part. Simply add a treecontrol with three links, and the treeview, to your page…   <div id="treecontrol">     <a title="Collapse the entire tree below" href="#"><img src="../images/minus.gif" /> Collapse All</a>     <a title="Expand the entire tree below" href="#"><img src="../images/plus.gif" /> Expand All</a>     <a title="Toggle the tree below, opening closed branches, closing open branches" href="#">Toggle All</a> </div> <ul id="treeview" class="treeview-black">     <li>Item 1</li>     <li>         <span>Item 2</span>         <ul>             <li>                 <span>Item 2.1</span>                   <ul>                     <li>Item 2.1.1</li>                     <li>Item 2.1.2</li>                 </ul>             </li>             <li>Item 2.2</li>             <li class="closed">                   <span>Item 2.3 (closed at start)</span>                 <ul>                     <li>Item 2.3.1</li>                     <li>Item 2.3.2</li>                 </ul>             </li>         </ul>     </li> </ul> …and then associate the control to the treeview when defining the treeview settings. $("#treeview").treeview({     control: "#treecontrol",     persist: "cookie",     cookieId: "treeview-black" }); It really couldn’t be easier and it works great! But the plugin doesn’t offer a lot of flexibility when it comes to layout.  For example, the plugin assumes your treecontrol will include links.  If you want buttons or images or whatever, you are out of luck.  The plugin also assumes a set number of links and the collapse all handler is associated with the first link inside of the treecontrol, a:eq(0), the expand all handler is associated with the second link and so on.  So you really can’t incorporate the toggle all link by itself unless you manually hide the other options. Which brings me to the point of this post – making the collapse/expand/toggle layout more flexible without modifying the plugin’s source code. We will continue to use the treecontrol actions but we’re not going to use them directly. In fact, our custom collapse, expand and toggle links will trigger the actions for us.  So, hide the treecontrol links and associate the treecontrol click events with the click events of other controls.  Finally, render the treeview with the same setting definitions as usual. $(document).ready(function() {     // The plugin shows the treecontrol after the     // collapse, expand and toggle events are hooked up     // Just hide the links.     $('#treecontrol a').hide();       // On click of your custom links, button, etc     // Trigger the appropriate treecontrol click     $('#expandAll').click(function() {                 $('#treecontrol a:eq(1)').click();         });          $('#collapseAll').click(function() {         $('#treecontrol a:eq(0)').click();             });       // Render the treeview per usual.         $("#treeview").treeview({         control: "#treecontrol",         persist: "cookie",         cookieId: "treeview-black"     }); }); Since I’m not using the treecontrol directly, I move it to the bottom of the page but it doesn’t really matter where the treecontrol goes. <div>     <a id="collapseAll" href="#">Collapse All Outside of TreeControl</a> </div>   <ul id="treeview" class="treeview-black">     <li>Item 1</li>     <li>         <span>Item 2</span>         <ul>             <li>                 <span>Item 2.1</span>                 <ul>                     <li>Item 2.1.1</li>                     <li>Item 2.1.2</li>                 </ul>             </li>             <li>Item 2.2</li>             <li class="closed">                 <span>Item 2.3 (closed at start)</span>                 <ul>                     <li>Item 2.3.1</li>                     <li>Item 2.3.2</li>                 </ul>             </li>         </ul>     </li> </ul>   <div>     <input type="button" id="expandAll" value="Expand All Outside of TreeControl"/> </div>   <div id="treecontrol">     <a href="#"></a><a href="#"></a><a href="#"></a> </div> The above jQuery and Html snippets generate the following ugly output which shows the separated collapse/expand elements. If you want the toggle all option, I bet you can figure out how to put it in place.  I’ve made the source available below if you’re interested.

  • Issue with Autofac 2 and MVC2 using HttpRequestScoped

    - by Page Brooks
    I'm running into an issue with Autofac2 and MVC2. The problem is that I am trying to resolve a series of dependencies where the root dependency is HttpRequestScoped. When I try to resolve my UnitOfWork (which is Disposable), Autofac fails because the internal disposer is trying to add the UnitOfWork object to an internal disposal list which is null. Maybe I'm registering my dependencies with the wrong lifetimes, but I've tried many different combinations with no luck. The only requirement I have is that MyDataContext lasts for the entire HttpRequest. I've posted a demo version of the code for download here. Autofac modules are set up in web.config Global.asax.cs protected void Application_Start() { string connectionString = "something"; var builder = new ContainerBuilder(); builder.Register(c => new MyDataContext(connectionString)).As<IDatabase>().HttpRequestScoped(); builder.RegisterType<UnitOfWork>().As<IUnitOfWork>().InstancePerDependency(); builder.RegisterType<MyService>().As<IMyService>().InstancePerDependency(); builder.RegisterControllers(Assembly.GetExecutingAssembly()); _containerProvider = new ContainerProvider(builder.Build()); IoCHelper.InitializeWith(new AutofacDependencyResolver(_containerProvider.RequestLifetime)); ControllerBuilder.Current.SetControllerFactory(new AutofacControllerFactory(ContainerProvider)); AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); } AutofacDependencyResolver.cs public class AutofacDependencyResolver { private readonly ILifetimeScope _scope; public AutofacDependencyResolver(ILifetimeScope scope) { _scope = scope; } public T Resolve<T>() { return _scope.Resolve<T>(); } } IoCHelper.cs public static class IoCHelper { private static AutofacDependencyResolver _resolver; public static void InitializeWith(AutofacDependencyResolver resolver) { _resolver = resolver; } public static T Resolve<T>() { return _resolver.Resolve<T>(); } } UnitOfWork.cs public interface IUnitOfWork : IDisposable { void Commit(); } public class UnitOfWork : IUnitOfWork { private readonly IDatabase _database; public UnitOfWork(IDatabase database) { _database = database; } public static IUnitOfWork Begin() { return IoCHelper.Resolve<IUnitOfWork>(); } public void Commit() { System.Diagnostics.Debug.WriteLine("Commiting"); _database.SubmitChanges(); } public void Dispose() { System.Diagnostics.Debug.WriteLine("Disposing"); } } MyDataContext.cs public interface IDatabase { void SubmitChanges(); } public class MyDataContext : IDatabase { private readonly string _connectionString; public MyDataContext(string connectionString) { _connectionString = connectionString; } public void SubmitChanges() { System.Diagnostics.Debug.WriteLine("Submiting Changes"); } } MyService.cs public interface IMyService { void Add(); } public class MyService : IMyService { private readonly IDatabase _database; public MyService(IDatabase database) { _database = database; } public void Add() { // Use _database. } } HomeController.cs public class HomeController : Controller { private readonly IMyService _myService; public HomeController(IMyService myService) { _myService = myService; } public ActionResult Index() { // NullReferenceException is thrown when trying to // resolve UnitOfWork here. // Doesn't always happen on the first attempt. using(var unitOfWork = UnitOfWork.Begin()) { _myService.Add(); unitOfWork.Commit(); } return View(); } public ActionResult About() { return View(); } }

  • Resolution Problem with HttpRequestScoped in Autofac

    - by Page Brooks
    I'm trying to resolve the AccountController in my application, but it seems that I have a lifetime scoping issue. builder.Register(c => new MyDataContext(connectionString)).As<IDatabase>().HttpRequestScoped(); builder.Register(c => new UnitOfWork(c.Resolve<IDatabase>())).As<IUnitOfWork>().HttpRequestScoped(); builder.Register(c => new AccountService(c.Resolve<IDatabase>())).As<IAccountService>().InstancePerLifetimeScope(); builder.Register(c => new AccountController(c.Resolve<IAccountService>())).InstancePerDependency(); I need MyDataContext and UnitOfWork to be scoped at the HttpRequestLevel. When I try to resolve the AccountController, I get the following error: No scope matching the expression 'value(Autofac.Builder.RegistrationBuilder`3+<c__DisplayClass0[...]).lifetimeScopeTag.Equals(scope.Tag)' is visible from the scope in which the instance was requested. Do I have my dependency lifetimes set up incorrectly?

  • What are the pro and cons of statically linking a library?

    - by Mathieu Pagé
    Hi, I want to release an application I developed as a hobby both for Linux and Windows. This application depends on boost (and possibly other libraries). The norm for this kind of application (a chess engine) is to provide only an executable file and possibly some helper files. I tough it would be a good idea to statically link the libraries so the executable would not have any dependencies. So the end user can just put the executable in a directory and start using it. However, while doing some research online I found some negative comments about statically linking libraries, some even arguing that an application with statically linked libraries would be hardly portable, meaning that it would only run on my system of highly similar systems. So what are the pros and cons of statically linking library? I already know that the executable will be bigger. But I can't see why it would make my application less portable.

  • Resolving HttpRequestScoped Instances outside of a HttpRequest in Autofac

    - by Page Brooks
    Suppose I have a dependency that is registered as HttpRequestScoped so there is only one instance per request. How could I resolve a dependency of the same type outside of an HttpRequest? For example: // Global.asax.cs Registration builder.Register(c => new MyDataContext(connString)).As<IDatabase>().HttpRequestScoped(); _containerProvider = new ContainerProvider(builder.Build()); // This event handler gets fired outside of a request // when a cached item is removed from the cache. public void CacheItemRemoved(string k, object v, CacheItemRemovedReason r) { // I'm trying to resolve like so, but this doesn't work... var dataContext = _containerProvider.ApplicationContainer.Resolve<IDatabase>(); // Do stuff with data context. } The above code throws a DependencyResolutionException when it executes the CacheItemRemoved handler: No scope matching the expression 'value(Autofac.Builder.RegistrationBuilder`3+<c__DisplayClass0[MyApp.Core.Data.MyDataContext,Autofac.Builder.SimpleActivatorData,Autofac.Builder.SingleRegistrationStyle]).lifetimeScopeTag.Equals(scope.Tag)' is visible from the scope in which the instance was requested.

  • Avoiding Service Locator with AutoFac 2

    - by Page Brooks
    I'm building an application which uses AutoFac 2 for DI. I've been reading that using a static IoCHelper (Service Locator) should be avoided. IoCHelper.cs public static class IoCHelper { private static AutofacDependencyResolver _resolver; public static void InitializeWith(AutofacDependencyResolver resolver) { _resolver = resolver; } public static T Resolve<T>() { return _resolver.Resolve<T>(); } } From answers to a previous question, I found a way to help reduce the need for using my IoCHelper in my UnitOfWork through the use of Auto-generated Factories. Continuing down this path, I'm curious if I can completely eliminate my IoCHelper. Here is the scenario: I have a static Settings class that serves as a wrapper around my configuration implementation. Since the Settings class is a dependency to a majority of my other classes, the wrapper keeps me from having to inject the settings class all over my application. Settings.cs public static class Settings { public static IAppSettings AppSettings { get { return IoCHelper.Resolve<IAppSettings>(); } } } public interface IAppSettings { string Setting1 { get; } string Setting2 { get; } } public class AppSettings : IAppSettings { public string Setting1 { get { return GetSettings().AppSettings["setting1"]; } } public string Setting2 { get { return GetSettings().AppSettings["setting2"]; } } protected static IConfigurationSettings GetSettings() { return IoCHelper.Resolve<IConfigurationSettings>(); } } Is there a way to handle this without using a service locator and without having to resort to injecting AppSettings into each and every class? Listed below are the 3 areas in which I keep leaning on ServiceLocator instead of constructor injection: AppSettings Logging Caching

  • ASP.Net Fails to Detect IE10 without .Net Hotfix

    - by Ben Barreth
    Benny Mathew recently alerted us that he couldn’t create, edit or delete posts on GeeksWithBlogs in IE10 (Windows 8). It turns out the problem is that ASP.Net fails to detect IE10 causing a javascript error on postback. We’ll be applying a hotfix to the .Net framework on GWB shortly to fix this issue. In the meantime you can use the simple workaround outlined below. (Note that if you create posts using Windows Live Writer you won’t have this issue creating posts). Log into your GWB Account and go to the “Posts” page. Hit F12 to bring up the developer window in IE10. Click on the ‘Browser Mode’ option and change it to IE9. You should now be able to create/edit/delete posts in GWB. Note this also fixes any other sites in IE10 that might not yet have the hotfix applied. You can tell if the hotfix is the likely culprit if you’re using IE10 and see the following error in the Web Developers Console area: SCRIPT5009: '__doPostBack' is undefined Let us know ASAP if there are other issues you are experiencing that aren’t fixed by this workaround!

  • How to convert the output of an artificial neural network into probabilities?

    - by Mathieu Pagé
    I've read about neural network a little while ago and I understand how an ANN (especially a multilayer perceptron that learns via backpropagation) can learn to classify an event as true or false. I think there are two ways : 1) You get one output neuron. It it's value is 0.5 the events is likely true, if it's value is <=0.5 the event is likely to be false. 2) You get two output neurons, if the value of the first is than the value of the second the event is likely true and vice versa. In these case, the ANN tells you if an event is likely true or likely false. It does not tell how likely it is. Is there a way to convert this value to some odds or to directly get odds out of the ANN. I'd like to get an output like "The event has a 84% probability to be true"

  • How do you populate a UIImage view with ASIHTTPRequest given @2x?

    - by Jonathan Page
    I've been trying to load images from a url using ASIHTTPRequest but I always come up with a blank UIImage. I think it might have something to do with iOS automatically choosing the @2x named version of images or vica versa. [ASIHTTPRequest setDefaultCache:[ASIDownloadCache sharedCache]]; NSString *url_string = [NSString stringWithFormat:@"http://173.246.100.185/%@", [eventDictionary objectForKey:kEventDescriptionImageURLKey]]; NSURL *url = [NSURL URLWithString:url_string]; __block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; [request setDownloadCache:[ASIDownloadCache sharedCache]]; [request setCachePolicy:ASIAskServerIfModifiedCachePolicy|ASIFallbackToCacheIfLoadFailsCachePolicy]; [request setCacheStoragePolicy:ASICachePermanentlyCacheStoragePolicy]; [request setSecondsToCache:86400]; [request setDelegate:self]; [request setCompletionBlock:^{ NSLog(@"Successful Update"); [self makeAssignment]; }]; [request setFailedBlock:^{ NSError *error = [request error]; NSLog(@"%@", [error localizedDescription]); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Update Failed" message:[error localizedDescription] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; }]; [request startAsynchronous]; NSLog(@"%@", url_string); The makeAssignment method is below. NSString *url_string = [NSString stringWithFormat:@"http://173.246.100.185/%@", [eventDictionary objectForKey:kEventDescriptionImageURLKey]]; NSURL *url = [NSURL URLWithString:url_string]; downloadedImage = [[UIImage alloc] initWithContentsOfFile:[[ASIDownloadCache sharedCache] pathToCachedResponseDataForURL:url]]; NSLog(@"%@", downloadedImage); NSLog(@"%@", [[ASIDownloadCache sharedCache] pathToCachedResponseDataForURL:url]); Nothing I do, including naming images @2x on the server or providing both versions, gets it to load. Any ideas? Has anyone done this before? When I load them locally (from within the package) I don't have any issues. Thanks!

  • How can I design a custom control in Javascript (possibly using jQuery)

    - by Mathieu Pagé
    I'd like to create a custom control in javascript. The goal is to create a building block that has methods, properties and events and render into a div. An example of one such control would be a calendar. It would render into a div, it would have properties that would define how it's displayed and what date is selected or highlighted, it would have methods to change the current month or to select some date and it would raise events when a day is clicked or the current month is changed by a user input. I can think of lots of way to implement this and I'm not sure what is the best way. I seem to remember that it's a bad thing to augment a DOM elements with properties and method, so I ruled that out. A jQuery plugin seems like a good idea, however I'm not sure if it's appropriate to create a plugin for each and every method my control would have so I could then use it like : $('#control').method1(); $('#control').method2(); And if I do use jQuery, where do I store the private data of my control? Another idea I got was to create a new kind of object that would have a reference to a div in which it could render it's elements. So what is the prefered way to do this. If I can I would like to do this as a jQuery plugin, but I'd need guidlines on how to create methods and where to store private data. I've loked at Plugins/Authoring on jQuery website and it did not helped that much in this regard.

  • ASP.NET make a panel visible on click of hyperlink (whilst also cuasing postback for page navigation

    - by Helen
    I may be asking the impossible but let me set out my problem: I have a menu in a MasterPage which uses images and mouseover mouseout events for design purposes. On one of the menu options I need to display a set of sub menus options on the click of the parent menu item. The menu item itself also needs to navigate to a specified url. I was originally trying to use an AJAX accordion panel but as I only had one accordion panel it was always displaying the sub menu items and was not collapsing. I have also tried putting the options in a div and setting the display via javascript. This worked but then was overwritten once the page navigation postback occurred.

  • Useful Excel keyboard shortcuts

    - by Ben Lings
    What keyboard shortcuts do you use in Excel? Things I've discovered recently and found very useful are: Shift + Space - select the current row Ctrl + Space - select the current column Ctrl + Shift + Space - select the block of contiguous cell Ctrl + + - Insert (as in the context menu). If the current row is selected, will insert a new row. Ctrl + - - Delete (as in the context menu). If the current row is selected, will delete entire row. What (apart from the normal cut, copy, paste, etc) do you use? Ctrl + 1 to open the Format dialog. Shift + F2 to add/edit a cell comment. Shift + F2, followed by Esc to select the current cell comment, which can then be moved around with the arrow keys (????) or deleted by pressing Del. Ctrl + ???? to move to the last non-blank cell in a series. This is usually the edge of a table, but not if you have blank cells in the path. Pressing End followed by an arrow key does the same thing. Alt + F11 to open the VBA editor. Alt + = to start a SUM() formula and go straight to selecting cells to be summed. Ctrl + G or F5 to jump to a cell by typing its coordinates (e.g. C3) Ctrl + Home to jump to the top left, usually A1 unless you you are in a frozen split view, in which case it will jump to the top left of the "data" area. Ctrl + ; and Ctrl + Shift + ; to insert the current date and time, respectively. I know Ben Lings already posted this one, but I find it indispensable.

  • Probelms Intstalling Trac using apt-get Ubuntu Jaunty

    - by Ben Waine
    Hi, I'm having some issues getting apt to install trac correctly on my Ubuntu Jaunty Box. Using the command 'apt-get install trac' I get the following output: root@myserver:~# apt-get install trac Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. Since you only requested a single operation it is extremely likely that the package is simply not installable and a bug report against that package should be filed. The following information may help to resolve the situation: The following packages have unmet dependencies: trac: Depends: python-setuptools (> 0.5) but it is not installable Depends: python-pysqlite2 (>= 2.3.2) but it is not going to be installed Depends: python-subversion but it is not installable Depends: libjs-jquery but it is not installable Recommends: python-pygments (= 0.6) but it is not installable or enscript but it is not installable Recommends: python-tz but it is not installable E: Broken packages I have successfully used the command on my karmic kola desktop machine and am able to create new projects etc. I thought I might be able to solve the problem by installing all python related extensions. This produced a very similar output. I have Main, universe and multi-verse repositories enabled. Its a remote machine and I have no access to the gui. Hope someone can help, googleing failed to solve the issue or find a solution! Thanks, Ben

  • Can you "swap" the Sysprep answer file in Windows 7

    - by Ben
    I have a load of new Lenovo laptops which I am due to distribute in my company. We are distributed in multiple locations and I want to ship the laptops "boxed" and untouched by IT hand for distribution. We are using LANDesk to do all the software distribution and provisioning, but are currently falling at the first hurdle as when booted, the laptops kick into the Lenovo mini-setup wizard. I assume this is because they have been sysprepped at Lenovo. In order to keep with our (almost) zero touch strategy I want the users to PXE boot into a PE of some sort, which will run a script on startup which replaces the sysprep answer file with one of my own. (i.e. prepopulated with product key, company info etc.) and then reboot to complete Sysprep. The plan is that this will run, and then install the LANDesk agent as a post-sysprep task, which in turn will complete the provisioning. Anyone have any experience / know any pitfalls to look out for / can suggest a suitable, PXE-bootable PE environment? Apologies for the verbosity of the question - it takes a bit of explaining! Thanks in advance, Ben
