  • How Can I Join Two DB Tables and Return Lowest Price From Joined Table

    - by Jason
    I have two tables, the first table has the product and the second table the prices. The price table could have more than one price per product but I only want to display the lowest. But I keep getting all the prices returned and I'm having trouble figuring out how to do it. this is what I get returned in my query: SELECT * FROM products AS pr JOIN prices AS p ON pr.id = p.product_id WHERE pr.live = 1 AND p.live = 1 id product1 name description £100 id product1 name description £300 id product1 name description £200 id product2 name description £50 id product2 name description £80 id product2 name description £60 id product3 name description £222 id product3 name description £234 id product3 name description £235 but I'm after: id product1 name description £100 id product2 name description £50 id product3 name description £222 Any help would be appreciated

  • Cloud sync between iPad/iPhone app

    - by Macatomy
    I have a Core Data app that will end up being an iPhone/iPad universal application. I would like to implement cloud syncing so that an iPhone and an iPad both running the app could share data. I'm planning to use the recently released Dropbox API. Does anyone have any thoughts on the best way to go about doing this? The Dropbox API allows for apps to store files on the cloud. What I was thinking was to original store the database (sqlite) for the app on the cloud and then download that database, but I then realized that using that method would make it painfully difficult to merge changes (rather than replacing the whole database). Any thoughts are appreciated. Thanks.

  • ASP.Net MVC + Live validation - how come the flagged text are all over the place?

    - by melaos
    hi guys, this is an asp.net mvc project and <% using (Html.BeginForm("ProductAdded", "Home")) { % Register Your Product <%= ViewData["MainHeader"]% <p><%=ViewData["IntroText"]%></p> <div style="display: none;"> <div id="regionThreePane"> <table border="0" cellpadding="0" cellspacing="0" frame="void" style="width: 100%"> <tr> <td width='250px'><select name="ProdLBox1" id="ProdLBox1" class="ProdLBox1" size="8"></select></td> <td width='250px'><select name="ProdLBox2" id="ProdLBox2" class="ProdLBox2" size="8"></select></td> <td width='250px'><select name="ProdLBox3" id="ProdLBox3" class="ProdLBox3" size="8"></select></td> </tr> </table> </div> i'm using live validation for my client side validation. var v_fname = new LiveValidation('Customer_FirstName', { validMessage: " " }, { onlyOnSubmit: true }); v_fname.add(Validate.Presence, { failureMessage: enterfirstname}); var v_lname = new LiveValidation('Customer_LastName', { validMessage: " " }); v_lname.add(Validate.Presence, { failureMessage: enterlastname }); var v_email = new LiveValidation('Customer_Email', { validMessage: " " }); v_email.add(Validate.Presence, { failureMessage: enteremail, validMessage: " " }); v_email.add(Validate.Email, { failureMessage: entervalidemail}); and what i notice is that after doing some button call: $(".btnAddProduct").click(function() { //Check first to see if there's anything to be added if (parseFloat($(".tboAddProduct").val()) < 1) { //TO DO: to replace with localized text var selectProductError = "Please select a product first"; $("#validationSummary").text(selectProductError); //alert("Please select a product first"); return false; } $(".PanelProductReg").show(); addProductRow($(".tboAddProductId").val(), $("#tboAddProduct").val()); }); what will happen is that the validation tags will start to appear for the whole page for all the input which are tag for the live validation. instead of just appearing when the controls are being higlighted and onblur. i'm using some ajax calls to get data and a lot of jquery to dynamically do the gui stuff. could any of this be causing some sort of an internal conflict? thanks

  • Compiling SQLite into programs that run on Symbian 9.1 and above?

    - by Jared
    How can I use SQLite C API’s on any device running Symbian OS 9.1 or above? While it appears that 9.4 comes with SQLite built in prior versions do not. Looking at http://sourceforge.net/projects/sqlites60/ it appears that sQLite has been ported to older Symbian releases. The only problem is this code assumes you want to use SQLite with .net when I want to compile it into a .sis file and call the C API’s. Ideally I’d compile a Symbian equivalent of amalgamation.c and call the sQLite functions directly but am not sure if this is possible.

  • Where I can find DeskUtil documentation/help?

    - by Born To Learn
    Hello all, Where I can find DeskUtil documentation/help? I am trying to build Delphi add-in and I have some troubles with saving/registering/loading the add-in docking form into the active IDE desktop. I am using the DeskUtil methods after reading some examples here and there, but, examples don’t go deep in how these methods work, and in the mechanism of the IDE loading/destroying. Is there any official documentation/help about the DeskUtil or the OpenTools Api? In other words, how and where can developer like me get deep knowledge (not articles or demos) about IDE and OpenTools Api? Thanks for your help.

  • RIM blackberry Record 3GP video

    - by pankaj_shukla
    Hi All, I am writing an application that can record a 3GP video. I have tried both MMAPI and Invoke API. But have following issues. Using MMAPI: 1. When I record to stream, It records video in RIMM streaming format. when I try to play this video player gives error "Unsupported media format.". 2. When I record to a file. It will create a file of size 0. Using Invoke API: 1. In MMS mode it does not allow to record a video more than 30 seconds. 2. In Normal mode size of the file is very large. 3. Once I invoke camera application I do not have any control on application. Here is my source code: _player = javax.microedition.media.Manager .createPlayer("capture://video?encoding=video/3gpp&mode=mms"); // I have tried every encoding returns from System.getProperty("video.encodings") method _player.realize(); _videoControl = (VideoControl) _player.getControl("VideoControl"); _recordControl = (RecordControl) _player.getControl("RecordControl"); _volumeControl = (VolumeControl) _player.getControl("VolumeControl"); String videoPath = System.getProperty("fileconn.dir.videos"); if (videoPath == null) { videoPath = "file:///store/home/user/videos/"; } _recordControl.setRecordLocation(videoPath + "RecordedVideo.3gp"); _player.addPlayerListener(this); Field videoField = (Field) _videoControl.initDisplayMode( VideoControl.USE_GUI_PRIMITIVE, "net.rim.device.api.ui.Field"); _videoControl.setVisible(true); add(videoField); _player.start(); ON start menu item Selection: try { _recordControl.startRecord(); } catch (Exception e) { _player.close(); showAlert(e.getClass() + " " + e.getMessage()); } On stop menuItem selection: try { _recordControl.commit(); } catch (Exception e) { _player.close(); showAlert(e.getClass() + " " + e.getMessage()); } Please let me if I am doing something wrong. Thanks, Pankaj

  • How to get the stream of a public Facebook fanpage in php?

    - by Bundy
    Hi, I want to display my public fanpage feed onto my website via the Facebook API without requiring a login. I'm doing this require_once('../includes/classes/facebook-platform/php/facebook.php'); $fb = new Facebook($api_key, $secret); $fb->api_client->stream_get('',$app_id,'0','0','','','','','')); But I get this error Fatal error: Uncaught exception 'FacebookRestClientException' with message 'user id parameter or session key required' in includes/classes/facebook-platform/php/facebookapi_php5_restlib.php:3065 Stack trace: #0 includes/classes/facebook-platform/php/facebookapi_php5_restlib.php(1915): FacebookRestClient->call_method('facebook.stream...', Array) #1 facebook/api.php(12): FacebookRestClient->stream_get('', 13156929019, '0', '0', 30, '', '', '', '') #2 {main} thrown in includes/classes/facebook-platform/php/facebookapi_php5_restlib.php on line 3065 Then I figured, because of 'user id parameter or session key required', to add my user id to the call require_once('../includes/classes/facebook-platform/php/facebook.php'); $fb = new Facebook($api_key, $secret); $fb->api_client->stream_get(502945616,13156929019,$app_id,'0','0','','','','','')); But then I got this error Fatal error: Uncaught exception 'FacebookRestClientException' with message 'Session key invalid or no longer valid' I'm totally clueless :)

  • How do I output JSON columns in jQuery

    - by Mel
    I'm using the qTip jQuery plugin to create dynamic tool tips. The tooltip sends an id to a cfc which runs a query and returns data in JSON format. At the moment, the tooltip loads with the following: {"COLUMNS:" ["BOOKNAME","BOOKDESCRIPTION"["MYBOOK","MYDESC"]]} Here's the jQuery $('#catalog a[href]').each(function() { var gi = parseInt($(this).attr("href").split("=")[1]) $(this).qtip( { content: { url: 'cfcs/viewbooks.cfc?method=bookDetails', data: { bookID: gi }, method: 'get', title: { text: $(this).text(), button: 'Close' } }, api :{ onContentLoad : function(){ } }, }); }); As I mentioned, the data is returned successfully, but I am unsure how to output it and format it with HTML. I tried adding content: '<p>' + data.BOOKNAME + '' to api :{ onContentLoad : function(){ ..... to see if I could get it to output something, but I get a 'data is undefined error' What is the correct way to try and output this data with html formatting? Many thanks!

  • sort associative array PHP

  • CakePHP repeats same queries

    - by Rytis
    I have a model structure: Category hasMany Product hasMany Stockitem belongsTo Warehouse, Manufacturer. I fetch data with this code, using containable to be able to filter deeper in the associated models: $this->Category->find('all', array( 'conditions' => array('Category.id' => $category_id), 'contain' => array( 'Product' => array( 'Stockitem' => array( 'conditions' => array('Stockitem.warehouse_id' => $warehouse_id), 'Warehouse', 'Manufacturer', ) ) ), ) ); Data structure is returned just fine, however, I get multiple repeating queries like, sometimes hundreds of such queries in a row, based on dataset. SELECT `Warehouse`.`id`, `Warehouse`.`title` FROM `beta_warehouses` AS `Warehouse` WHERE `Warehouse`.`id` = 2 Basically, when building data structure Cake is fetching data from mysql over and over again, for each row. We have datasets of several thousand rows, and I have a feeling that it's going to impact performance. Is it possible to make it cache results and not repeat same queries?

  • Duplicate Blob field with foreach

    - by JGSilva
    I have some fields (blob) where I have uploaded some images. The images display correctly and I can open it without problem in Photoshop for example. I created a button where user can duplicate the product and everything works fine, but when it comes to duplicate the image entry I got some errors, like 1064 and others ones that I can't remember cause I am working 3 days inside this. Because de original product have 3 or more images I select then and gave an foreach. What I notice when a print de blob is that in the end it eats the next array, like if don't have an end. In other words, the next item got inside that utf-8 character in the print. That gave me some clue. The next approach was to save it in somewhere, and reupload it. The problem is that only the first one works. When I download the image saved, it opens normally so, it is not a saving in disk problem. When I gave a print in the $result, the same happens, is like the image is hungry and ate the next one. Here is the code. Notice = I created the [$count] to see if was not an rewrite in array error. Even tried to , in beging of the foreach, kind of clean the vars… $count=0; foreach ($original_image as $key => $val) { $count++; //$arquivo = ''; //$image = ''; //$file = ''; //$this->image = ''; //$return = ''; $arquivo[$count] = $val['pi_id'].'.'.$val['pi_type']; $image[$count] = $caminho_url.$arquivo[$count]; if (file_exists($image[$count])) { $this->image = Image::factory($image[$count]); $this->image->save($image[$count]); $file[$count]=mysql_real_escape_string(addslashes(fread(fopen($image[$count], "r"), filesize($image[$count])))); $return[$count] = Product::add_image($id_prod, $file[$count], $val['pi_type'],$val['pi_main']); }else { die('no'); } }

  • How to tell if running in a linux console versus an ssh session?

    - by Stéphane
    I have an application that needs to behave differently if run directly from the linux console. So if a user connects with SSH to run FooBar, or the user walks over to the console and logs in directly to run FooBar, I want it to do something different. What C API do I need to call to tell the difference between these two scenarios? I was thinking I'd have to look at the "tty/pts" information (such as what I see when I run "ps axf"), but I'm not certain if that is the best solution, nor what API to call to get that information. Hints appreciated. :)

  • Gson serialization depending on field value

    - by Serj Lotutovici
    I have a POJO that is similar to: public class MyGsonPojo { @Expose @SerializedName("value1") private String valueOne; @Expose @SerializedName("value2") private boolean valueTwo; @Expose @SerializedName("value3") private int valueThree; // Getters and other stuff here } The issue is that this object has to be serialized into a json body for a call to the server. Some fields are optional for the request and if I even send it with default and null values, the API responds differently (Unfortunately changing the api is not an option). So basically I need to exclude fields from serialization if any of them is set to a default value. For example if the field valueOne is null the resulting json should be: { "value2" : true, "value3" : 2 } Any idea how to make this a painless effort? I wouldn't want to build the json body manually. Any help would be great. Thank you in advice.

  • Jquery check if element exists then add class to different element

    - by Buddy
    I don't know much about jquery at all, so bear with my ignorance, but I'm pretty sure I can accomplish this with jquery. I need jquery to check if an element exists, and if so, add a class to a different element. For example, if class "minimal-price-link" exists, then add a class to "regular-price" or what I really am wanting to do is make the regular-price strikethrough. Here's the code: <div class="price-box"> <span class="regular-price" id="product-price-2"> <span class="price">$240.00</span> </span> <a href="http://stemulation.com/order/sfs30.html" class="minimal-price-link"> <span class="label">Your Price:</span> <span class="price" id="product-minimal-price-2">$110.00</span> </a> </div>

  • What encoding does Flash Builder use to send non-English data to servers?

    - by Ole Jak
    In my site I use Unicode... I hoped when I'll connect Flash Builder to my server (using Data - connect to HTTP ) It will work with my API sending Russian text as UTF-8 but instead it sends Þûõó ïúушúøý to my API and so to DB and so on instead of my favourite UTF-8 &#1056;&#1091;&#1089;&#1089;&#1082;&#1086;&#1077; &#1048;&#1084;&#1103; 2... So what encoding uses flash builder and How to make Flash Application send UTF-8 data to my server or some other readable format?

  • How to overload shutdown function?

    - by Michal M
    I am using Kohana (v3) framework but I believe it's not tied to a particular framework. What I have is basically an app with a front-end, where I want to use Kohana's native Kohana::shutdown_handler(), but I also have a part of the - RESTful API - where I don't want colourful and html-encoded exception reporting. I want a plain text reporting. The way I thought it might work is to register another shutdown function in API's controller abstract class constructor, but then I realised register_shutdown_function() works differently to set_exception_handler() and instead of replacing it adds another function to the shutdown procedure. What's worse PHP doesn't allow "unregistering" shutdown functions and that's where my problem lies. What to do, if you want to use another shutdown function instead of one already registered?

  • Serial numbers generation without user data

    - by Sphynx
    This is a followup to this question. The accepted answer is generally sufficient, but requires user to supply personal information (e.g. name) for generating the key. I'm wondering if it's possible to generate different keys based on a common seed, in a way that program would be able to validate if those keys belong to particular product, but without making this process obvious to the end user. I mean it could be a hash of product ID plus some random sequence of characters, but that would allow user to guess potential new keys. There should be some sort of algorithm difficult to guess.

  • How to write custom SQLite functions in Javascript inside a Webkit browser?

    - by Jay Godse
    I have just learned how to use the SQLite database for local storage in a Webkit web browser (e.g. Google Chrome or Apple Safari) using the Javascript API. For example the "Sticky Notes" application. However, I know that SQLite has a function called sqlite_create_function() that lets you add custom functions to your instance of SQLite on the fly which can then be used inside SQL queries. This function is described at sqlite.org. I also know that you can call an equivalent of this API in Ruby as described here. QUESTION: Can anybody show me how to do this in Javascript - i.e. write a custom function in Javascript that can be bound into the SQLite database at run time to be called by the SQLite engine, and all inside a Webkit browser?

  • What's the "right" way to get Win32 p/Invoke declarations?

    - by Daniel Earwicker
    I typically use the site http://www.pinvoke.net/ to grab a DllImport declaration whenever I need to call a Win32 API, and I've noticed it's the de facto standard response on Stack Overflow to API interop questions. Is this what "everyone" does? Is there a better way? Does Microsoft offer an alternative? e.g. a tool that reads .h files and outputs an assembly. Why aren't there some standard assemblies that just expose all the Win32 APIs? What would be the barrier to creating them and using them, as an alternative to a site like pinvoke.net?
