  • The right approach to loading dynamic content into a UITableView in iOS

    - by OS.
    ok, I've read tons of bits and pieces on the subject of loading dynamic content (from the web) into a UITableView and the problem with calculating cell height upfront. I've tried different simple implementations but the problem persists... Assuming I need to read a JSON file from the web, parse it into 'item' objects, each with variable size image and various text labels, here is what I believe would be the right approach to avoid long hang time of the app while everything is loading: on app load read JSON file and parse into items array provide only small part of the items array to the tableview (about 10 items) - since I need to load the images associated with each item to calculate cell height - I don't want the view to go through the whole items list and load all images - this hangs the app until every image is loaded display the tableview with the available cells (assuming I load a few 'spare' ones, user can even scroll to more items) in the background using Grand Central Dispatch download images for all/some of the remaining items and then reload the tableview with the new data (repeat step 4 if item list is very long) Step 2 above is necessary since I have no way to calculate the cell height without loading the images first, and since tableview first calculates height of all cells it may take a very long time to download all images for all items. Would you say this is the right approach? am I missing something?

  • c# How to implement a collection of generics

    - by Amy
    I have a worker class that does stuff with a collection of objects. I need each of those objects to have two properties, one has an unknown type and one has to be a number. I wanted to use an interface so that I could have multiple item classes that allowed for other properties but were forced to have the PropA and PropB that the worker class requires. This is the code I have so far, which seemed to be OK until I tried to use it. A list of MyItem is not allowed to be passed as a list of IItem even though MyItem implements IItem. This is where I got confused. Also, if possible, it would be great if when instantiating the worker class I don't need to pass in the T, instead it would know what T is based on the type of PropA. Can someone help get me sorted out? Thanks! public interface IItem<T> { T PropA { get; set; } decimal PropB { get; set; } } public class MyItem : IItem<string> { public string PropA { get; set; } public decimal PropB { get; set; } } public class WorkerClass<T> { private List<T> _list; public WorkerClass(IEnumerable<IItem<T>> items) { doStuff(items); } public T ReturnAnItem() { return _list[0]; } private void doStuff(IEnumerable<IItem<T>> items) { foreach (IItem<T> item in items) { _list.Add(item.PropA); } } } public void usage() { IEnumerable<MyItem> list= GetItems(); var worker = new WorkerClass<string>(list);//Not Allowed }

  • Implementing inotifycollectionchanged interface

    - by George
    Hello, I need to implement a collection with special capabilities. In addition, I want to bind this collection to a ListView, Therefore I ended up with the next code (I omitted some methods to make it shorter here in the forum): public class myCollection<T> : INotifyCollectionChanged { private Collection<T> collection = new Collection<T>(); public event NotifyCollectionChangedEventHandler CollectionChanged; public void Add(T item) { collection.Insert(collection.Count, item); OnCollectionChange(new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Add, item)); } protected virtual void OnCollectionChange(NotifyCollectionChangedEventArgs e) { if (CollectionChanged != null) CollectionChanged(this, e); } } I wanted to test it with a simple data class: public class Person { public string GivenName { get; set; } public string SurName { get; set; } } So I created an instance of myCollection class as follows: myCollection<Person> _PersonCollection = new myCollection<Person>(); public myCollection<Person> PersonCollection { get { return _PersonCollection; } } The problem is that the ListView does not update when the collection updates although I implemented the INotifyCollectionChanged interface. I know that my binding is fine (in XAML) because when I use the ObservableCollecion class instead of myCollecion class like this: ObservableCollection<Person> _PersonCollection = new ObservableCollection<Person>(); public ObservableCollection<Person> PersonCollection { get { return _PersonCollection; } } the ListView updates What is the problem?

  • Icons in menu are smaller than they should be

    - by martinpelant
    Hello I have a little problem. All the icons in my apk are smaller than the same icons in other apps (Gmail etc.) This is how it looks like in my apk and this is the same icon in Gmail.apk. I have copied these icons directly from SDK to the specific folders for hdpi, mdpi and ldpi. Here is an example of a hdpi icon I use and my menu.xml <?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/refresh" android:title="@string/refresh" android:icon="@drawable/ic_menu_refresh" /> <item android:id="@+id/add" android:title="@string/add" android:icon="@drawable/ic_menu_add" /> <item android:id="@+id/login" android:title="@string/account" android:icon="@drawable/ic_menu_login" /> </menu> Does anybody know how to make these icon have the same size as in other apk's? I have tried the asset studio with no effect. UPDATE: If I reference an icon directly from android (android:drawable) then it has normal size. However not all icons can be referenced.

  • EventKitUI view and edit problem!

    - by Alish
    I try to to find a solution to do View and Edit of a the item from a tablview. My application base on UITabBarController. Each of the Bar items contain a class with a a couple of UIViews. This is the first items of UITabBarController. I done Add event from Apple sample code: SimpleEKDemo. Add Event working without any problem. I tried to add View and Edit part to the code. I would able to select an items from tableView to edit the selected item. But after I tried to add code from SimpleEKDemo to my code, I realized I have to add UINavigationController to the implement. So I did. After I add that it's came to the items of UITabBarController. Also I even the Add Event didn't worked very well (I couldn't insert event name and location. but edit was working. So I need to know: 1- Is it possible to implement Edit/View without using UINavigationController. If yes please let me know a sample code. 2- If I must use UINavigationController. Because I don't need UINavigationController to become it the first page and I don't need any bar added to my application. Is it possible it's appear in the application when I choose a item of tableView but appear alike that! Snapshots: https://public.me.com/alish (pict.zip)

  • Iterate over defined elements of a JS array

    - by sibidiba
    I'm using a JS array to Map IDs to actual elements, i.e. a key-value store. I would like to iterate over all elements. I tried several methods, but all have its caveats: for (var item in map) {...} Does iterates over all properties of the array, therefore it will include also functions and extensions to Array.prototype. For example someone dropping in the Prototype library in the future will brake existing code. var length = map.lenth; for (var i = 0; i < length; i++) { var item = map[i]; ... } does work but just like $.each(map, function(index, item) {...}); They iterate over the whole range of indexes 0..max(id) which has horrible drawbacks: var x = []; x[1]=1; x[10]=10; $.each(x, function(i,v) {console.log(i+": "+v);}); 0: undefined 1: 1 2: undefined 3: undefined 4: undefined 5: undefined 6: undefined 7: undefined 8: undefined 9: undefined 10: 10 Of course my IDs wont resemble a continuous sequence either. Moreover there can be huge gaps between them so skipping undefined in the latter case is unacceptable for performance reasons. How is it possible to safely iterate over only the defined elements of an array (in a way that works in all browsers and IE)?

  • Pass 2-dimensional array trough view

    - by Mikael
    Hi, I'm trying to print a 2-dimensional array but can't figure it out. My controller uses this code: public ActionResult Test(string str) { DateTimeOffset offset = new DateTimeOffset(DateTime.Now); offset = offset.AddHours(-5); string[,] weekDays = new string[7,2]; for (int i = 0; i < 7; i++) { weekDays[i,0] = String.Format("{0:yyyy-MM-dd:dddd}", offset); //Date weekDays[i,1] = String.Format("{0:dddd}", offset); //Text offset = offset.AddHours(24); } weekDays[0,1] = "Today"; ViewData["weekDays"] = weekDays; return View(); } Now I wan't to print this array of weekdays as a dropdown-list and i thought this would work: <% foreach (var item in (string[,])ViewData["weekDays"]) { %> <option value=" <%= item[0] %> "> <%= item[1] %> </option> <% } %> But that's not the case, this code output just the first char of the string. So anyone got a suggestion? Thanks! /M

  • retaining the form inputs on clicking the submit button

  • How do you create a generic method in a class?

    - by Seth Spearman
    Hello, I am really trying to follow the DRY principle. I have a sub that looks like this? Private Sub DoSupplyModel OutputLine("ITEM SUMMARIES") Dim ItemSumms As New SupplyModel.ItemSummaries(_currentSupplyModel, _excelRows) ItemSumms.FillRows() OutputLine("") OutputLine("NUMBERED INVENTORIES") Dim numInvs As New SupplyModel.NumberedInventories(_currentSupplyModel, _excelRows) numInvs.FillRows() OutputLine("") End Sub I would like to collapse these into a single method using generics. For the record, ItemSummaries and NumberedInventories are both derived from the same base class DataBuilderBase. I can't figure out the syntax that will allow me to do ItemSumms.FillRows and numInvs.FillRows in the method. FillRows is declared as Public Overridable Sub FillRows in the base class. Thanks in advance. EDIT Here is my end result Private Sub DoSupplyModels() DoSupplyModelType("ITEM SUMMARIES",New DataBlocks(_currentSupplyModel,_excelRows) DoSupplyModelType("DATA BLOCKS",New DataBlocks(_currentSupplyModel,_excelRows) End Sub Private Sub DoSupplyModelType(ByVal outputDescription As String, ByVal type As DataBuilderBase) OutputLine(outputDescription) type.FillRows() OutputLine("") End Sub But to answer my own question...I could have done this... Private Sub DoSupplyModels() DoSupplyModelType(Of Projections)("ITEM SUMMARIES") DoSupplyModelType(Of DataBlocks)("DATA BLOCKS") End Sub Private Sub DoSupplyModelType(Of T as DataBuilderBase)(ByVal outputDescription As String, ByVal type As T) OutputLine(outputDescription) dim type as New T(_currentSupplyModel,_excelRows) type.FillRows() OutputLine("") End Sub Is that right? Does the New T() work? Seth

  • How to use vertical-align: middle; properly?

    - by Andrew
    I want to have my list (nav) align to the center of an image (logo). I tried using vertical-align: middle;, but I couldn't get it to work when I floated the images left and right. Here's my code: HTML: <div id="head"> <img id="logo" src="logo.png" /> <ul id="nav"> <li><a href="#">Item 1</a></li> <li><a href="#">Item 2</a></li> <li><a href="#">Item 3</a></li> </ul> </div> CSS: #head { margin-top: 2px; width: 100%; } #logo { float: left; } ul#nav { float: right; } ul#nav li { display: inline; list-style-type: none; } I took all the vertical-align: middle;'s from where I put them (I tested it in each element, even though it was only supposed to be applied to #logo, from what I've read.) Anyways, any help would be appreciated.

  • What is the best way to properly test object equality against an array of objects?

    - by radesix
    My objective is to abort the NSXMLParser when I parse an item that already exists in cache. The basic flow of the program works like this: 1) Program starts and downloads an XML feed. Each item in the feed is represented by a custom object (FeedItem). Each FeedItem gets added to an array. 2) When the parsing is complete the contents of the array (all FeedItem objects) are archived to the disk. The next time the program is executed or the feed is refreshed by the user I begin parsing again; however, since a cache (array) now exists as each item is parsed I want to see if the object exists in the cache. If it does then I know I have downloaded all the new items and no longer need to continue parsing. What I am learning, I think, is that I can't use indexOfObject or indexOfObjectIDenticalTo: because these really seem to be checking to see that the objects are using the same memory address (thus identical). What I want to do is see if the contents of the object are equal (or at least some of the contents). I've done some research and found that I can override the IsEqual method; however, I really don't want to iterate/enumerate through the entire cache contents table for every newly parsed XML FeedItem. Is iterating through the collection and testing each one for equality the only way to do this or is there a better technique I am not aware of? Currently I am using the following code though I know it needs to change: NSUInteger index = [self.feedListCache.feedList indexOfObject:self.currentFeedItem]; if (index == NSNotFound) { }

  • Rails 4 testing bug?

    - by Jamato
    Situation: if we add two identic line items into a cart, we update line item quantity instead of adding a duplicate.In browser everything works fine but in unit testing section something fails because of an empty cycle in code. Which I wanted to use to update all prices. Why? Is that a unit test engine bug? LineItem.all and cart.line_items in process of testing produce two DIFFERENT structures. #<LineItem id: 980190964, product_id: 1, cart_id: 999, created_at: "2014-06-01 00:21:28", updated_at: "2014-06-01 00:21:28", quantity: 2, price: #<BigDecimal:ba0fb544,'0.4E1',9(27)>> #<LineItem id: 980190964, product_id: 1, cart_id: 999, created_at: "2014-06-01 00:21:28", updated_at: "2014-06-01 00:21:28", quantity: 1, price: #<BigDecimal:ba0d1b04,'0.4E1',9(27)>> cart.line_items guy did not update quantity Code itself (produces LineItem which is then saved in line_item_controller which calls this method) class Cart < ActiveRecord::Base has_many :line_items, dependent: :destroy def add_product(product_id) # LOOK THIS CYCLE BREAKS UNIT TEST, SRSLY, I MEAN IT line_items.each do |item| end current_item = line_items.find_by(product_id: product_id) fresh_price = Product.find_by(id: product_id).price if current_item current_item.quantity += 1 else current_item = line_items.build(product_id: product_id, price: fresh_price) end return current_item end ...

Even with cycle. I feel so dumb right now...

  • geb StaleElementReferenceException

    - by Brian Mortenson
    I have just started using geb with webdriver for automating testing. As I understand it, when I define content on a page, the page element should be looked up each time I invoke a content definition. //In the content block of SomeModule, which is part of a moduleList on the page: itemLoaded { waitFor{ !loading.displayed } } loading { $('.loading') } //in the page definition moduleItems {index -> moduleList SomeModule, $("#module-list > .item"), index} //in a test on this page def item = moduleItems(someIndex) assert item.itemLoaded So in this code, I think $('.loading') should be called repeatedly, to find the element on the page by its selector, within the context of the module's base element. Yet I sometimes get a StaleElementReference exception at this point. As far as I can tell, the element does not get removed from the page, but even if it does, that should not produce this exception unless $ is doing some caching behind the scenes, but if that were the case it would cause all sorts of other problems. Can someone help me understand what's happening here? Why is it possible to get a StaleElementReferenceException while looking up an element? A pointer to relevant documentation or geb source code would be useful as well.

  • Linq based generic alternate to Predicate<T>?

    - by Eric
    I have an interface called ICatalog as shown below where each ICatalog has a name and a method that will return items based on a Predicate<Item> function. public interface ICatalog { string Name { get; } IEnumerable<IFamily> GetItems(Predicate<Item> predicate); } A specific implementation of a catalog may be linked to catalogs in various format such as XML, or a SQL database. With an XML catalog I end up deserializing the entire XML file into memory, so testing each item with the predicate function does does not add a whole lot more overhead as it's already in memory. Yet with the SQL implementation I'd rather not retrieve the entire contents of the database into memory, and then filter the items with the predicate function. Instead I'd want to find a way to somehow pass the predicate to the SQL server, or somehow convert it to a SQL query. This seems like a problem that can be solved with Linq, but I'm pretty new to it. Should my interface return IQueryable instead?

  • jquery $.ajax load in UI dialog() problem

    - by alex
    i have a working bing Image search api with jsonp datatype. It's working with no problems. When i load the image search script in a Jquery UI dialog, it display properly and i'm able to search and see the results in the dialog() box. But if i close the dialog() and open it again, now if i search no results show. Looking at console.log, i do confirm the jason data is recieved, but for some reason it's not appending to the result div, so i see no result on the screen. This onyl happens if i close the dialog and open it again. If i refresh refresh the page and open the dialog again then search results are displayed. This is what i'm using to append the results. $.each(data.SearchResponse.Image.Results, function(i, item) { console.log(item.Thumbnail.Url); $("#Results").append("<li><img style='width:100px; height:75px;' src='" + item.Thumbnail.Url + "'/></li>"); });

  • How to determine which element(s) are visible in an overflowed <div>

    - by jjross
    Basically, I'm trying to implement a system that behaves similar to the reading pane that's built into the Google Reader interface. If you haven't seen it, Google Reader presents each article in a separate box and as you scroll it highlights the current box (and marks the article as read). In addition to this, you can move forward or backward in the article list by clicking the previous and next buttons in the UI. I've basically figured out how to do most of the functionality. However, I'm not sure how I can determine which of my divs is currently visible in in the scrollable pane. I have a div that is set to overflow:auto. Inside of this div, there are other divs, each one containing a piece of content. I've used the following jquery plugin to make everything scroll based on a click of the "next" or "previous" button and it works like a charm: http://demos.flesler.com/jquery/serialScroll/ But I can't tell which div has "focus" in the scrollable pane. I'd like to be able to do this for two reasons. I'd like to highlight the item that the user is currently reading (similar to Google Reader). I need to do this regardless of whether or not they used the plugin to get there or used the browser's scroll bar. I need to be able to tell the plugin which item has focus so that my call to scroll to the "next" pane actually uses the currently viewed pane (and not just the previous pane that the plugin scrolled from). I've tried doing some searching but I can't seem to figure out a way to do this. I found lots of ways to scroll to a particular item, but I can't find a way to determine which element is visible in an overflowed div. If I can determine which items are visible, I can (probably) figure out the rest. I'm using jquery if that helps. Thanks!

    I have lists of variable length where each item can be one of four unique, that I need to use as keys for another object in a map. Assume that each value can be either 0, 1, 2 or 3 (it's not integer in my real code, but a lot easier to explain this way) so a few examples of key lists could be: [1, 0, 2, 3] [3, 2, 1] [1, 0, 0, 1, 1, 3] [2, 3, 1, 1, 2] [1, 2] So, to re-iterate: each item in the list can be either 0, 1, 2 or 3 and there can be any number of items in a list. My first approach was to try to hash the contents of the array, using the built in GetHashCode() in .NET to combine the hash of each element. But since this would return an int I would have to deal with collisions manually (two equal int values are identical to a Dictionary). So my second approach was to use a quad tree, breaking down each item in the list into a Node that has four pointers (one for each possible value) to the next four possible values (with the root node representing [], an empty list), inserting [1, 0, 2] => Foo, [1, 3] => Bar and [1, 0] => Baz into this tree would look like this: Grey nodes nodes being unused pointers/nodes. Though I worry about the performance of this setup, but there will be no need to deal with hash collisions and the tree won't become to deep (there will mostly be lists with 2-6 items stored, rarely over 6). Is there some other magic way to store items with lists of values as keys that I have missed?

  • exchange server 2010 Outlook Web Access - Exchange Control Panel WEB Interface

    - by Aceth
    from what i can gather the mailbox bit of the web interface works fine.. when any of the users go to options (top right) and try to use some of the features such as the Organise Mail Delivery Reports to find messages etc... it comes up with a message .. "An item with the same key has already been added" I've looked in the event viewer and i think its this error - Watson report about to be sent for process id: 7016, with parameters: E12IIS, c-RTL-AMD64, 14.00.0639.021, ECP, ECP.Powershell, https://x.x.x.x/ecp/PersonalSettings/Accounts.svc/GetList, UnexpectedCondition:ArgumentException, c09, 14.00.0639.021. ErrorReportingEnabled: False and Request for URL 'https://x.x.x.x/ecp/PersonalSettings/Accounts.svc/GetList' failed with the following error: System.ArgumentException: An item with the same key has already been added. at System.ServiceModel.AsyncResult.End[TAsyncResult](IAsyncResult result) at System.ServiceModel.Activation.HostedHttpRequestAsyncResult.End(IAsyncResult result) at System.ServiceModel.Activation.HostedHttpRequestAsyncResult.ExecuteSynchronous(HttpApplication context, Boolean flowContext) at Microsoft.Exchange.Management.ControlPanel.WebServiceHandler.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) I've tried googling but no luck that's relevant :(

  • Windows 7 KSOD On Login

    - by Brandon Bertelsen
    For those that are unaware, KSOD means blacK Screen of Death. Essentially, when windows starts my computer shows only the cursor and a black screen. It seems like any and all shell elements are disabled (or perhaps not started). I have seen a number of these questions asked, none of which have matched my situation. CTRL + ALT + ... does not respond Restarting in safe mode, results in the same KSOD sfc /scannow seems to have no effect when typed at the command prompt that is accessed using the recovery tools via the install disk Update to item 3: sfc /scannow reports: There is a system repair pending which requires reboot to complete. Restart Windows and run sfc again. However, Windows does not restart past KSOD. Update to item 3 as per Soandos comment re: /offbootdir sfc /scannow /offbotdir=e:\ /windir=e:\windows "Windows resource protection found corrupt files but was unable to fix some of them. Details are included in the CBS.log..."

  • Why does my motherboard go through an endless reboot cycle when 8 GB of memory is attempted vs 6 GB?

    - by nizm0
    I never got an answer in my googling to this about a year ago and have an extra stick of memory I'd like to be able to use. When is inserted the computer starts, and then reboots immediately in an endless reboot cycle. As soon as the 4th stick is removed, the computer works fine. Right now I have 6 GB of my 8 GB installed. Is there a solution that I am missing to enabling this motherboard to actually boot up with all 8 GB (it supports it). Right now it won't even boot up to BIOS with the 4 sticks... only 3?
