  • How do you detect when the Flowplayer has started playing the video?

    - by Alex
    Hi. I'm using the Flowplayer Flash video player to play MP4 videos inside an AnythingSlider. I need to detect when the user has clicked the start button on the video so to stop the slideshow and allow the user to view the video. I've tried using this code just to get an alert box but it doesn't do anything (the code is at the end of the page, before the closing </body> tag): <script type="text/javascript"> $f("player","global/js/flowplayer/flowplayer-3.1.5.swf",{ onStart: function(clip) { alert('player started'); } }); </script> The Flowplayer is implemented as part of the html5media library, which automatically detects whether the browser can handle the <video> tag; if not, it replaces the anchor tag below with the Flowplayer: <video id="vid" width="372" height="209" poster="global/vid/bbq-poster.jpg" controls preload> <source id="videoSource" src="global/vid/BBQ_Festival.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' onerror="fallback(this.parentNode)" ></source> <a href="global/vid/BBQ_Festival.mp4" style="display:block;width:372px;height:209px; padding-left:5px; " id="player"> </a> </video> So the $f() function call is in a JavaScript block at the end of the page, to give the player a chance to load correctly. What am I doing wrong? Thanks.

  • Is there anything wrong with my Factory class?

    - by Alex
    class PieceFactory { @SuppressWarnings("rawtypes") public Piece createPiece(String pieceType) throws Throwable{ Class pieceClass = Class.forName(pieceType); Piece piece = (Piece) pieceClass.newInstance(); return piece; } } I'm not all used to handling exceptions yet therefore I'm just throwing them, but everywhere I use a method that uses this factory it tells me I have to throw exceptions like throwable. For example, in one of my classes I have a method that instantiates a lot of objects using the method that uses the factory. I can use the method in that class by just throwing the exception, however it won't work if I try to pass a reference to that class to another class and then use the method from there. Then it forces me to try catch the exception. I probably don't need a factory but it seemed interesting and I'd like to try to use patterns. The reason I created the factory was that I have 6 subclasses of Piece and I wan't to use a method to instantiate them by passing the type of subclass I want as an argument to the method.

  • Paging in ActiveRecord

    - by Alex
    Does CastleProject ActiveRecord support paging? I need to load only data which is now seen on the screen. If I use [HasMany], it will be loaded as a whole either immediately or at the first call (if lazy attribute is true). However I only need something like first 100 records (then maybe 100 next records). Another question is how to load only 100 items. If the collection is too big, memory can reach its limit if we constantly load more and more items.

  • LINQ to SQL: making a "double IN" query crashes

    - by Alex
    I need to do the following thing: var a = from c in DB.Customers where (from t1 in DB.Table1 where t1.Date >= DataTime.Now select t1.ID).Contains(c.ID) && (from t2 in DB.Table2 where t2.Date >= DataTime.Now select t2.ID).Contains(c.ID) select a It doesn't want to run. I get the following error: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. But when I try to run var a = from c in DB.Customers where (from t1 in DB.Table1 where t1.Date >= DataTime.Now select t1.ID).Contains(c.ID) select a OR var a = from c in DB.Customers where (from t2 in DB.Table2 where t2.Date = DataTime.Now select t2.ID).Contains(c.ID) select a It works! I'm sure that there both IN queries contain some customers ids.

  • Why does my entire page reload in Chrome and Firefox when using asynchronous UpdatePanel postbacks?

    - by Alex
    Being a bit perplexed about this issue by now, I hope some of you gurus can shed some light on my problem... I've developed a AJAX-enhanced website, which has been running fine in IE, Chrome and Firefox for a year or so. I use a Timer-control to check for incoming messages every 30 seconds, and this updates an UpdatePanel showing potential new messages. Now several one of my Firefox users complain about the page refreshing every 30 seconds! I my self cannot reproduce this behaviour, but given the "30 seconds"-description, I cursed my Timer-solution as the culprit. But now, I'm experiencing this error myself, not in Firefox though, but in Google Chrome! (And only on one of my two computers!) Every 30 seconds the page reloads! But I found that it's not only related to the Timer, because all other asynchronous postbacks to the server within UpdatePanels reloads the entire page as well. This error has never been experienced in Internet Explorer (to my knowledge). As I said, this it not only related to the Timer postback, but if it's of interest to anybody the code is like this: <asp:Timer runat="server" ID="MailCheckTimer" Interval="30000" OnTick="MailChecker_Tick"></asp:Timer> <asp:UpdatePanel runat="server" ID="MailCheckerUpdatePanel" UpdateMode="Conditional"> <ContentTemplate> <div class="newmail_box" runat="server" id="newmail_box"> <!-- Content stripped for this example --> </div> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="MailCheckTimer" /> </Triggers> </asp:UpdatePanel> In other places of the website I call the client side __doPostBack function directly from JavaScript in relation to an UpdatePanel. Normal behaviour for this call is to updated the referenced UpdatePanel with some content, but now in Chrome this refreshes the entire page! (but again not consistently, and never in IE) Even the most fundamental UpdatePanel operations like refreshing the content after a button (inside the panel) is clicked, forces the page to reload completely: <asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="btnSearch_Click"></asp:Button> And just to torment me further, I only experience this on my public website, and not in my local development environment, making it a tedious affair for me to find the actual cause! :( Any ideas on why this happens? Why so inconsistently? Has it to do with my UpdatePanel-design? Or does some security setting in Firefox/Chrome that prevent some asynchronous UpdatePanel callbacks? Any help or idea is highly appreciated!

  • Linq ChangeConflictException (ASP.NET MVC) - occurs when submitting DataContext changes

    - by Alex
    System.Data.Linq.ChangeConflictException: 2 of X updates failed. at System.Data.Linq.ChangeProcessor.SubmitChanges(ConflictMode failureMode) at System.Data.Linq.DataContext.SubmitChanges(ConflictMode failureMode) at PROJECT.Controllers.HomeController.ClickProc(Int32 id, String code, String n) This is what I get very often. This action is done thousands of times a day, and I get this exception about once every 5 seconds. From what I understand it happens when something changes in the database in the period between creating DataContext and updating it. Am I right? What's the problem here and how can I fix it?

  • Why is this HTTP request continually looping?

    - by alex
    I'm probably overlooking something really obvious here. Comments are in to help explain any library specific code. public function areCookiesEnabled() { $random = 'cx67ds'; // set cookie cookie::set('test_cookie', $random); // try and get cookie, if not set to false $testCookie = cookie::get('test_cookie', false); $cookiesAppend = '?cookies=false'; // were we able to get the cookie equal ? $cookiesEnabled = ($testCookie === $random); // if $_GET['cookies'] === false , etc try and remove $_GET portion if ($this->input->get('cookies', false) === 'false' AND $cookiesEnabled) { url::redirect(str_replace($cookiesAppend, '', url::current())); // redirect return false; } // all else fails, add a $_GET[] if ( ! $cookiesEnabled) { url::redirect(url::current().$cookiesAppend); } return $cookiesEnabled; }

  • help me to choose between two software architecture

    - by alex
    // stupid title, but I could not think anything smarter I have a code (see below, sorry for long code but it's very-very simple): namespace Option1 { class AuxClass1 { string _field1; public string Field1 { get { return _field1; } set { _field1 = value; } } // another fields. maybe many fields maybe several properties public void Method1() { // some action } public void Method2() { // some action 2 } } class MainClass { AuxClass1 _auxClass; public AuxClass1 AuxClass { get { return _auxClass; } set { _auxClass = value; } } public MainClass() { _auxClass = new AuxClass1(); } } } namespace Option2 { class AuxClass1 { string _field1; public string Field1 { get { return _field1; } set { _field1 = value; } } // another fields. maybe many fields maybe several properties public void Method1() { // some action } public void Method2() { // some action 2 } } class MainClass { AuxClass1 _auxClass; public string Field1 { get { return _auxClass.Field1; } set { _auxClass.Field1 = value; } } public void Method1() { _auxClass.Method1(); } public void Method2() { _auxClass.Method2(); } public MainClass() { _auxClass = new AuxClass1(); } } } class Program { static void Main(string[] args) { // Option1 Option1.MainClass mainClass1 = new Option1.MainClass(); mainClass1.AuxClass.Field1 = "string1"; mainClass1.AuxClass.Method1(); mainClass1.AuxClass.Method2(); // Option2 Option2.MainClass mainClass2 = new Option2.MainClass(); mainClass2.Field1 = "string2"; mainClass2.Method1(); mainClass2.Method2(); Console.ReadKey(); } } What option (option1 or option2) do you prefer ? In which cases should I use option1 or option2 ? Is there any special name for option1 or option2 (composition, aggregation) ?

  • How can I use JSONP to download client-side javascript objects?

    - by Alex Mcp
    I'm trying to get client-side javascript objects saved as a file locally. I'm not sure if this is possible. The basic architecture is this: Ping an external API to get back a JSON object Work client-side with that object, and eventually have a "download me" link This link sends the data to my server, which processes it and sends it back with a mime type application/json, which (should) prompt the user to download the file locally. Right now here are my pieces: Server Side Code <?php $data = array('zero', 'one', 'two', 'testing the encoding'); $json = json_encode($data); //$json = json_encode($_GET['']); //eventually I'll encode their data, but I'm testing header("Content-type: application/json"); header('Content-Disposition: attachment; filename="backup.json"'); echo $_GET['callback'] . ' (' . $json . ');'; ?> Relevant Client Side Code $("#download").click(function(){ var json = JSON.stringify(collection); //serializes their object $.ajax({ type: "GET", url: "http://www.myURL.com/api.php?callback=?", //this is the above script dataType: "jsonp", contentType: 'jsonp', data: json, success: function(data){ console.log( "Data Received: " + data[3] ); } }); return false; }); Right now when I visit the api.php site with Firefox, it prompts a download of download.json and that results in this text file, as expected: (["zero","one","two","testing the encoding"]); And when I click #download to run the AJAX call, it logs in Firebug Data Received: testing the encoding which is almost what I'd expect. I'm receiving the JSON string and serializing it, which is great. I'm missing two things: The Actual Questions What do I need to do to get the same prompt-to-download behavior that I get when I visit the page in a browser (much simpler) How do I access, server-side, the json object being sent to the server to serialize it? I don't know what index it is in the GET array (silly, I know, but I've tried almost everything)

  • Weird behavior of an ASP.NET MVC application - track of errors

    - by Alex
    Before migrating from ASP.NET WebForms I had a very good way to monitor all my application errors in the Events Log (Administrative Tools). But now after moving to asp.net MVC, all I get is the same mistake occurring every minute (something about Site Master). I know it's not right, because there are other mistakes, but they are not displayed. I purposefully put in division by zero operation, and it didn't track it. I had to implement the OnException method of a controller, and send e-mails with error details which is very inconvenient. How can I solve this problem?

  • Automated Java to Scala source code conversion?

    - by Alex R
    (Yes I know I can call Java code from Scala; but that is pointless; I want to DELETE the Java code, not keep it around and have to look at it and maintain it forever!) Are there any utilities out there to convert Java source to Scala source? I believe theoretically it should be possible to accomplish with minimal lossage. I have found this but it seems inactive, probably buggy/incomplete... http://sourceforge.net/projects/java2scala/ Any alternatives?

  • How can I create/update an XML node that may or may not exist?

    - by ScottBai
    Is there a method available (i.e. without me creating my own recursive method), for a given xpath (or other method of identifying the hierarchical position) to create/update an XML node, where the node would be created if it does not exist? This would need to create the parent node if it does not exist as well. I do have an XSD which includes all possible nodes. i.e. Before: <employee> <name>John Smith</name> </employee> Would like to call something like this: CoolXmlUpdateMethod("/employee/address/city", "Los Angeles"); After: <employee> <name>John Smith</name> <address> <city>Los Angeles</city> </address> </employee> Or even a method to create a node, given an xpath, wherein it will recursively create the parent node(s) if they do not exist? As far as the application (if it matters), this is taking an existing XML doc that contains only populated nodes, and adding data to it from another system. The new data may or may not already have values populated in the source XML. Surely this is not an uncommon scenario?

  • jQuery draggable leaving cloned html behind

    - by Alex Crooks
    I am using jQuery UI; Draggable http://jqueryui.com/demos/draggable invoked like this: $(document).ready(function(){ $("#side_bar").sortable({ revert: true }); $(".draggable").draggable({ containment: 'parent', hascroll: true, handle: 'div.box_header', scrollSensitivity: 100, scrollSpeed: 100, axis: 'y', connectToSortable: '#side_bar', helper: 'clone', opacity: 0.35 }); }); You can see the html structure on http://www.sarsclan.co.uk (right side bar area). It seems to create a transparant clone as your dragging, but when you drop it puts the draggable div in the right place, but leaves the original div in it's place and just appends the dom with a clone of that original div in its new place.
