  • Strategy to lazy load images for buttons within UIScrollView?

    - by greypoint
    I have a horizontal UIScrollView that contains UIButtons (though it could be any object). I would like to only download images for these buttons as the user scrolls and they are seen. I would also like an activityindicator running on each button while the images are downloading. Here's what I've tried with results: Check content offset of uiscrollview and download images for visible buttons. Problem: issues getting activity view shown within subclassed UIButton and not desired usability since images are only downloaded once scrolling stops. Add subviews (not buttons) to the UIScrollview hoping to use the view's ViewController to initiate a downloaded on viewDidAppear. Problem: viewDidAppear never seems to get called (because I am using addSubView?). I've seen other apps that do this kind of loading but need some guidance on the typical set-up. Ebay's app is a great example. All items have a default image until the item comes into view, then an activityindicator runs and the items unique image is downloaded. Thanks for assistance.

  • NHibernate: QueryOver<> help

    - by Andy Baker
    Hi, I'm just starting out with NHibernate and I'm having trouble with running more complex queries. I have entities with a list of tags attached. The user will provide two lists of tags, include and exclude. I need to find all the entities that have all of the include tags, and exclude any entites that have any tag in the exclude list. Below is my first effort- which is clearly wrong as its listing all Display objects that have any of the include tags rather than all! Any assistance is greatly appeciated. var includeTagIds = (from tag in regime.IncludeTags select tag.Id).ToList<int>(); var excludeTagIds = from tag in regime.ExcludeTags select tag.Id; var displays = session.QueryOver<Display>() .JoinQueryOver<DisplayTag>(display => display.Tags) .WhereRestrictionOn(tag => tag.Id) .IsIn(includeTagIds).List().Distinct(); return displays.ToList();

  • HttpWebResponse with MJPEG and multipart/x-mixed-replace; boundary=--myboundary response content typ

    - by arri.me
    I have an ASP.NET application that I need to show a video feed from a security camera. The video feed has a content type of 'multipart/x-mixed-replace; boundary=--myboundary' with the image data between the boundaries. I need assistance with passing that stream of data through to my page so that the client side plugin I have can consume the stream just as it would if I browsed to the camera's web interface directly. The following code does not work: //Get response data byte[] data = HtmlParser.GetByteArrayFromStream(response.GetResponseStream()); if (data != null) { HttpContext.Current.Response.OutputStream.Write(data, 0, data.Length); } return;

  • SQL Server -> 'SQL_Latin1_General_CP1_CI_AS' Collation -> Varchar Column -> Languages Supported

    - by Ajay Singh
    All, We are using SQL Server 2008 with Collation Setting as 'SQL_Latin1_General_CP1_CI_AS'. We are using Varchar column to store textual data. We know that we cannot store Double Byte data in Varchar column and hence cannot support languages like Japanese and Chinese without converting it to NVarchar. However, will it be safe to say that all Single Byte Characters can be stored in Varchar column without any problem? If yes then from where can I get the list of languages which needs Single Byte for storage and the list of languages which needs double byte? Any assistance in this regard is highly appreciated. Thanks in advance.

  • Visual Studio and SQL Server - correct installation sequence?

    - by cdonner
    I am rebuilding my development machine. This issue is not new to me, but I don't remember the solution. I started with VS 2008 Pro, then SQL 2008 Developer, then the SQL SP1, then VS SP1. The result is that I cannot open SSIS projects (see the error below). What is the correct order so that I can avoid the installation of SQL Server Express and still have all the features working? --------------------------- Microsoft Visual Studio --------------------------- Package Load Failure Package 'DataWarehouse VSIntegration layer' has failed to load properly ( GUID = {4A0C6509-BF90-43DA-ABEE-0ABA3A8527F1} ). Please contact package vendor for assistance. Application restart is recommended, due to possible environment corruption. Would you like to disable loading this package in the future? You may use 'devenv /resetskippkgs' to re-enable package loading. --------------------------- Yes No ---------------------------

  • Facebook graph API - OAuth Token

    - by Simon R
    I'm trying to retrieve data using the new graph API, however the token I'm retriving from OAuth doesn't appear to be working. The call I'm making is as follows; $token = file_get_contents('https://graph.facebook.com/oauth/access_token?type=client_cred&client_id=<app_id>&client_secret=<app secret>'); This returns a token with a string length of 41. To give you an example of what is returned I have provided below a sample (converted all numbers to 0, all capital letters to 'A' and small case letters to 'a' access_token=000000000000|AaaAaaAaaAAaAaaaaAaaAa0aaAA. I take this access token and attach it to the call request for data, it doesn't appear to be the correct token as it returns nothing. I make the data call as follows; file_get_contents('https://graph.facebook.com/<my_page's_id>/statuses?access_token=000000000000|AaaAaaAaaAAaAaaaaAaaAa0aaAA.') When I manually retrieve this page directly through the browser I get an 500/Internal Server Error Message. Any assistance would be grately appreciated.

    I am trying to make a page which displays some user information returned from active directory.

    - by tonsils
    Hi, Hoping to get some assistance but I am after a jQuery/PHP means of allowing a user to drag and drop files and then via PHP, upload one or more files to a specific directory on a Linux box. I only have Firefox 3.6 as my base browser but can also move to FFox if need be. Cann use any HTML5 features as long as I'm using Firefox 3.6 Can someone possibly point me to any examples/sites where this process is demonstrated? I have had a look at http://www.plupload.com/index.php but this does not work in IE6. As mentioned, would like it to work in FFox only. Thanks.

  • JQuery Validation Plugin: Use Custom Ajax Method

    - by namtax
    Hi Looking for some assistance with the Jquery form validation plugin if possible. I am validating the email field of my form on blur by making an ajax call to my database, which checks if the text in the email field is currently in the database. // Check email validity on Blur $('#sEmail').blur(function(){ // Grab Email From Form var itemValue = $('#sEmail').val(); // Serialise data for ajax processing var emailData = { sEmail: itemValue } // Do Ajax Call $.getJSON('http://localhost:8501/ems/trunk/www/cfcs/admin_user_service.cfc?method=getAdminUserEmail&returnFormat=json&queryformat=column', emailData, function(data){ if (data != false) { var errorMessage = 'This email address has already been registered'; } else { var errorMessage = 'Good' } }) }); What I would like to do, is encorporate this call into the rules of my JQuery Validation Plugin...e.g $("#setAdminUser").validate({ rules:{ sEmail: { required: function(){ // Replicate my on blur ajax email call here } }, messages:{ sEmail: { required: "this email already exists" } }); Wondering if there is anyway of achieving this? Many thanks

  • Does Sandcastle support Entity Framework Partial Classes?

    - by ChrisHDog
    I am attempting to use Sandcastle (and Sandcastle Help File Builder) to do some "auto-documentation" of some classes I am using. The classes that are giving me trouble are some partial classes on Entity Framework items that add methods and properties to those Framework items. The triple slash comments don't appear to come through on the methods and properties created in the partial classes. I have out how to get xml documentation of the base properties using the short summary and long description fields on the .emdx editor, but that doesn't provide a solution for the items in the partial classes. Is this possible? Is it perhaps just settings that I'm not setting correctly to pick up the partial classes? Does Sandcastle do partial classes in non-Entity Framework settings? Is what I'm doing even possible (has anyone else successfully used the xml created from triple slash comments to create documentation on entity framework partial classes, and if so how did you do that)? Any assistance is appreciated

  • Macromedia Flash 8 - Ireland Map, on mouseover dublin, dublin expands

    - by DJDonaL3000
    Macromedia Flash 8 Question: I have a map of Ireland, just a gif, and there are several small buttons representing various point of interest around Ireland, which are scattered across the map. This part works fine. THE PROBLEM: Dublin is too small to contain all of its points of interest (approx 20). THE SOLUTION OnMouseOver Dublin, I would like Dublin to expand to perhaps 5 or 6 times its original size, and I would like to be able to have Dublins Points Of Interests now displayed within this larger dublin area, which sits on top of the Ireland map. OnMouseOut Dublin, this enlarged Dublin region now shrinks back to its original size. MY QUESTION: How do I implement Dublin?? REQUIREMENTS: 1) The expanded Dublin region shud NOT be clickable, it shud simply be a dublin image on a black background. 2) It must be possible to add additional buttons within this expanded Dublin region. Any help or assistance greatly appreciated...

  • JSF2 ResourceBundleLoader override?

    - by CDSO1
    I need to have resource messages that contain EL expressions be resolved when loaded from a ResourceBundle. Basically I have a number of properties files containing the text. Some of the text will look like the following: welcomeText=Welcome #{userbean.name} The only possible way I can see this working currently is implementing a custom taglib so that instead of saying: <f:loadBundle var="messages" basename="application.messages"/> I would have to use <mytaglib:loadBundle var="messages" basename="application.messages"/> #{messages.welcomeText} Given a user with username "User1", this should output Welcome User1 My implementation would then use a custom ResourceBundle class that would override handleGetObject, use the ELResolver to resolve variables etc....Ideas? suggestings? Implementations that are already available? I appreciate your assistance.

  • How to implement eCommerce susbscription service with multiple products

    - by Todd Brooks
    I've been researching eCommerce payment gateways and service offerings, but I'm an eCommerce novice, so please excuse my ignorance. I wish to set up an eCommerce solution with the following requirements: User "subscribes" to the service on a yearly basis. This service includes a single product subscription for a set amount (let's say $50/yr). User can "subscribe" to additional product services for a lesser rate per year (let's say $25/yr). I will need to store a product service unique Id of some sort for each product subscription the user subscribes to in order to show them product unique information. I also need to prevent duplicates...for example, user can subscribe to product ABC and XYZ, but not 2 of ABC. Is PayPal the best solution for something like this? Is there a better solution? Any assistance is greatly appreciated, even if just links to specific tutorials or examples. Update: It looks like Chargify could be the perfect solution.

  • setting jQuery .data() within .getJSON callback

    - by hackmaster.a
    I'm doing a couple of .getJSON calls and if any one of them succeeds, I'm trying to set a bool to true so I can then do some other stuff elsewhere on the page. I was trying to use jquery's .data() function, but I don't seem able to set it from inside the .getJSON callback. for example: $('#citations_button').data('citations', false); $.getJSON(apaurl, function(data) { $('#apacite').html("<td class=\"bibInfoLabel\">APA Citation</td><td class=\"bibInfoData\">"+data+"</td>"); $('#citations_button').data('citations', true); }, "html"); // other .getJSONs look like above... console.log("citations? "+$('#citations_button').data('citations')); prints false, even when I know the data came through. I thought this would work since .data() uses the cache to store the key/value pair. how can i flag successes?? appreciate any assistance!!

  • Need to compare blobs in firebird

    - by Michael Beck
    Hey guys, I need to check on the contents of blobs in my databases (yes, plural, but one problem at a time). In one database, I have about 900 images of potentially varying sizes. I need to check to see if the versioning system that's built into our application is actually correctly replicating the image data from the previous version to the new version of a record. How do I compare values en masse so I don't have to pick through each record one at a time and open up the blob using FlameRobin or Firebird Maestro and visually compare these images? Thanks for any assistance.

  • Jquery post success variable scope

    Hi, I'm trying to return the ajax success array from one function to another. For some reason I don't seem to be able to pass the data stored in a variable in the success part of the ajax function into the parent function to return. Thanks so much for any assistance. Here's a simplified version of the code: // make json_to_return global var json_to_return; function loop_through_data(){ // call the load_days function and put its array data into days_array var days_data = load_days(03,2010); // I'd like to be able to iterate through days_data here // // } function load_days(selectedMonth, selectedYear){ $.ajax({ type: "POST", dataType: "json", url: "../includes/get_availability.php", data: "month=" + selectedMonth + "&year=" + selectedYear, success: function(available_json){ json_to_return = available_json; }, error: function(msg){ alert("error " + msg); } }); return json_to_return; }

  • Constructing a hash table/hash function.

    - by nn
    Hi, I would like to construct a hash table that looks up keys in sequences (strings) of bytes ranging from 1 to 15 bytes. I would like to store an integer value, so I imagine an array for hashing would suffice. I'm having difficulty conceptualizing how to construct a hash function such that given the key would give an index into the array. Any assistance would be much appreiated. The maximum number of entries in the hash is: 4081*15 + 4081*14 + ... 4081 = 4081((15*(16))/2) = 489720. So for example: int table[489720]; int lookup(unsigned char *key) { int index = hash(key); return table[index]; } How can I compute hash(key). I'd preferably like to get a perfect hash function. Thanks.

  • Entity Relationship Diagram - Relationship Strength?

    - by 01010011
    Hi, I am trying to figure out under what circumstances I should use weak (non-identifying) relationships (where the primary key of the related entity does not contain a primary key component of the parent entity), verses when I should use strong (identifying) relationships (primary key of the related entity contains a primary key component of the parent entity). For example, when designing an Entity Relationship Diagram , if I have two entities, (e.g. book and purchaser), how do I know when to choose the solid Crows Foot or the dashed Crows Foot to connect the two entities? Any assistance will be appreciated. Thanks in advance.
