  • How could I implement a fuzzy time date replacer using Knockout?

    - by rball
    I'd like to implement what this plugin does using jQuery: https://github.com/rmm5t/jquery-timeago A short description of that plugin: This will turn all abbr elements with a class of timeago and an ISO 8601 timestamp in the title (conforming to the datetime design pattern microformat): <abbr class="timeago" title="2011-12-17T09:24:17Z">December 17, 2011</abbr> Into something like this: <abbr class="timeago" title="December 17, 2011">about 1 day ago</abbr> Except using knockout my markup looks like this: <abbr data-bind="attr: { title: Posted }" class="timeago"></abbr> I think something isn't synced up because nothing is happening even if I put the call to timeago within the viewmodel itself. I'm guessing I need a subscriber that's attached to the observable "Posted" but I'm not sure how to set that up.

  • Coupling an MFC CListCtrl and CTreeCtrl to get a view of the whole tree, not just one node at a time

    - by omatai
    Consider Windows Explorer (or regedit or similar). To the left side, there is a tree view, and to the right, a list view. In all cases I know of, the contents of the right view reflect the attributes of the selected node from the left pane. This is all well and good... but just not what I want. The nodes of the tree I want to display have a very few attributes (2-3) associated with each node - a reasonable amount to display horizontally as a row in a table. Rather than waste all that list view space on a single node with very few properties, I would like to have my list view display a table of the whole tree's properties (as the part of the tree currently expanded). So the nth line in the left view (tree) will correspond directly to the nth line in the right view (list/table), and I will get a decent overview of the properties of my tree. Does anyone know of code that does this? I am guessing that slaving a CListCtrl to a CTreeCtrl would be the way to go, and somehow overriding the vertical scrolling functions so that they are locked together. I'm just not sure that it is possible to lock the scrolls together like this... among other things! All advice gratefully welcomed :-)

  • (Cocoa) Can I Subclass and Delegate at the same time?

    - by Alvin
    @interface ClassB <ClassADelegate> : ClassA id <ClassBDelegate> delegate; @end As the code says, ClassB subclasses from ClassA and handles the formation protocol of Class A. However, the variable "delegate" will be duplicated. (ClassA also has "delegate") In fact, it can be done without subclassing, but it seems the code is cumbersome, i.e., to use a variable/function of ClassA, I need to write [[ClassB classA] doSomething] instead of [classB doSomething], where doSomething: is a function of ClassA. Are there any tidy way for me to do that?

  • Multiple depends in ant task

    - by glowcoder
    If I have three targets, one "all", one "compile" and one "jsps", how would I make "all" depend on the other two Would it be <target name="all" depends="compile,jsps"> or would it be <target name="all" depends="compile","jsps"> Or maybe something even different? I tried searching for example ant scripts to base it off of, but I couldn't find one with multiple depends. Thanks!

  • Compiling Enet in iphone xcode project

    - by EToreo
    Hello, I am trying to compile the Enet source code into my code framework for iPhone games. After modifying the header files I get it compiling and linking, but I absolutely must be compiling with the "Compile Source As" set to "Objective-C++" in my xcode project (because the framework code requires this). When I flip this switch in my test project, I get these errors: Undefined symbols: "_enet_list_clear", referenced from: _enet_host_connect in host.o ... Can anyone help get this linking with "Compile Source As" set to "Objective-C++"?

    - by David
    Hi, i'm using loadmovie() to load a youtube video player inside my flash website but when i load another video the old one doesn't stop, so i tried unloadmovie to destroy it but it seems that i did a mistake in my code This is how the code looks to stop the old one an load the new: vloader.unloadMovie(); vloader.loadMovie("http://www.youtube.com/v/Alw5hs0chj0&hl=fr&fs=1hJ-mPcGtC"); How to do that? please don't suggest me to use other objects or classes, i only want to edit that code.

  • How can I plot a time series graph with Perl?

    - by Jazz
    I have some data from a database (SQLite), mapping a value (an integer) to a date. A date is a string with this format: YYYY-MM-DD hh:mm. The dates are not uniformly distributed. I want do draw a line graph with the dates on X and the values on Y. What is the easiest way to do this with Perl? I tried DBIx::Chart but I could not make it recognize my dates. I also tried GD::Graph, but as the documentation says: GD::Graph does not support numerical x axis the way it should. Data for X axes should be equally spaced

  • How would I show an HTML page in Eclipse at Design Time?

    - by 1.21 gigawatts
    When I'm writing crappy code in eclipse and I'm looking at a website for help I am constantly flipping back and forth between the browser and eclipse. To help me write crappy code faster is there a way to have a View that has a web page in it? I need to be able to set the URL and if I'm navigating around the site have a button to have it return to the original URL. So a URL Address box and 1 favorite link. BTW I'm not a Eclipse plugin developer.

  • Trying to grab several random videos from database, but it just shows the same one all the time.

    - by Birk
    Hi guys, I'm trying to grab several random videos from my database, and have them show on a page. However, it just keeps on grabbing the same video rather than several different ones. So I end up with 5 of the same video rather than 5 different ones. Here's the grab random PHP code file... and after it is the template output file. //===================================================== // Random | Previous | Next //===================================================== $show['random'] = $db->quick_fetch( "SELECT file_id, title, title_seo, category_id, thumb FROM files WHERE files.category_id = '".$show['main']['category_id']."' AND files.verified=1 ORDER BY RAND() LIMIT 0,1; "); Here's the template CSS html thingy code I have this pasted 5 times to show 5 random videos <td valign="top" width="53%"><? $sql="select * from files ORDER BY rand() limit 0,5"; $res=@mysql_query($sql); $data=@mysql_result($res,0,'filename'); $id=@mysql_result($res,0,'file_id'); $title=@mysql_result($res,0,'title'); $title2=str_replace(" ", "-",$title); $path="{$siteurl}/media/{$file.random.file_id}/{$file.random.title_seo}/"; $img="{$siteurl}/thumbs/{$file.random.thumb}"; echo " {$file.random.title}"

  • How can I implement "real time" messaging on Google AppEngine?

    - by Freed
    I'm creating a web application on Google AppEngine where I want the user to be notified a quickly as possible after certain events occour. The problem is similar to say a chat server in that I need something happening on one connection (someone is writing a message in a chat room) to propagate to a number of other connections (other people in that chat room gets the message). To get speedy updates from the server to the client I'm planning on using long polling with XmlHttpRequest, hoping that AppEngine won't interfere other than possibly restriing the timeout. The real problem however is efficient notification between connections on AppEngine. Is there any support for this type of cross connection notification on AppEngine that does not involve busy-waiting? The only tools I can think of to do this at all is either using the data storage (slow) or memcache (unreliable), and none of them would let me avoid busy-waiting. Note: I know about XMPP support on AppEngine. It's related, but I want a browser based solution, sending messages to the users by XMPP is not an option.

  • How can I display the camera view in the main window in real time?

    - by Mongrel Warfare
    I'm trying to make an augmented reality application with a waypoint structure, like Yelp, and I'm wondering how to set up my main view so that it displays the camera view on the whole screen. I've heard of using the UIImagePickerController Class, but I'm unsure how to manipulate the code so that it doesn't actually take a picture, but just stays in the view mode. Any help would be appreciated, thanks!

  • How can I get Text property to initialize to the objects name at design time?

    - by cyclotis04
    When you add a label to the form from the toolbox, its text defaults to the item's name (label1, label2, etc). How can I make this happen with a custom control? So far, I have the following, which allows me to change the text through the property window: private string _text; [BrowsableAttribute(true)] public override string Text { get { return _text; } set { _text = value; lblID.Text = _text; } } Apparently the above code works as is, but I'm not sure why. Does Text default to the object's name automatically? The question still stands for other properties which don't override Text.

  • Is it possible to exit a for before time in C++, if an ending condition is reached?

    - by tunnuz
    Hello, I want to know if it is possible to end a for loop in C++ when an ending condition (different from the reacheing right number of iterations) is verified. For instance: for (int i = 0; i < maxi; ++i) for (int j = 0; j < maxj; ++j) // But if i == 4 < maxi AND j == 3 < maxj, // then jump out of the two nested loops. I know that this is possible in Perl with the next LABEL or last LABEL calls and labeled blocks, is it possible to do it in C++ or I should use a while loop? Thank you.

  • Why does DateTime to Unix time use a double instead of an integer?

    - by Earlz
    I'm needing to convert a DateTime to a Unix timestamp. So I googled it looking for some example code In just about all the results I see, they use double as the return for such a function, even when explicitly using floor to convert it to an integer. Unix timestamps are always integers. So what problem is there with using either long or int instead of double? static double ConvertToUnixTimestamp(DateTime date) { DateTime origin = new DateTime(1970, 1, 1, 0, 0, 0, 0); TimeSpan diff = date - origin; return Math.Floor(diff.TotalSeconds); }

  • How to set an alarm to fire properly at fixed time?

    - by Pentium10
    I have this code Calendar c = new GregorianCalendar(); c.add(Calendar.DAY_OF_YEAR, 1); c.set(Calendar.HOUR_OF_DAY, 23); c.set(Calendar.MINUTE, 22); c.set(Calendar.SECOND, 0); c.set(Calendar.MILLISECOND, 0); // We want the alarm to go off 30 seconds from now. long firstTime = SystemClock.elapsedRealtime(); firstTime += 30*1000; long a=c.getTimeInMillis(); // Schedule the alarm! AlarmManager am = (AlarmManager)ctx.getSystemService(Context.ALARM_SERVICE); am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, c.getTimeInMillis(), 1*60*60*1000, sender); It is not executed at 23:22h What I am doing wrong? I noticed firstTime and c.getTimeInMillis() differs a lot in size and length. When I use firstTime, so when set to 30 seconds, the alarm is executed well.

  • Can't switch tab and replace value of an input and call a f() same time.

    - by marharépa
    Hi! I feel sorry of askin all my little thingys here, but i can't find the answer via google. :( I'd like to switch tabs, replace an input value and call a function by one click. THE JS: function ApplyTableId(id) { var $tabs = $('#tabs').tabs(); $('a.stat').click(function() { $tabs.tabs('select', 2); // switch to third tab }); $('tableId').val('ga:'+id); // replace the input with id=tableId's val getAccountFeed(); // call an other function } The another JS, which will be called by the first script: function getAccountFeed() { var myFeedUri = 'https://www.google.com/analytics/feeds/accounts/default?max-results=50'; myService.getAccountFeed(myFeedUri, handleAccountFeed, handleError); } This is what i want to call, and here is the HTML: TAB1: <a class="stat" onClick="return ApplyTableId(this.getAttribute('id'));" id="7777777" />asd</a> TAB3: <input type="text" value="asd" id="tableId"/> Please tell me, what i did wrong :(

  • JQuery: Live <a> tag partially working second time around.

    - by BPotocki
    I have the following jquery code: $("a[id*='Add_']").live('click', function() { //Get parentID to add to. var parentID = $(this).attr('id').substring(4); //Get div. var div = $("#CreateList"); //Ajax call to refresh "CreateList" div with new XML. div.load("/AddUnit?ParentID=" + parentID); }); Basically, contained within the div is a nested unordered list with several "Add_#" links. Clicking the links uses an ajax call to recreate the list with a new node. It clears all the add links, but they are added again by the ajax call. This is why I used the .live method so newly added "Add_#" links still have the binding. This works in most cases. If I click "Add_1", the div refreshes with the new info. If I then click "Add_2", it works again as expected. The problem I'm having happens when I click "Add_1", then the page refreshes (and creates a new "Add_1" link), then I click the re-rendered "Add_1" again. It's the same link, but it was refreshed during the ajax call. When I do that, the javascript function still gets called, but the .load method doesn't work. Any ideas why this might be happening? Thanks.

  • Is it possible that two requests at the same time double this code? (prevent double database entry)

    - by loostro
    1) The controller code (Symfony2 framework): $em = $this->getDoctrine()->getEntityManager(); // get latest toplist $last = $em->getRepository('RadioToplistBundle:Toplist')->findOneBy( array('number' => 'DESC') ); // get current year and week of the year $week = date('W'); $year = date('Y'); // if: // [case 1]: $last is null, meaning there are no toplists in the database // [case 2]: $last->getYear() or $last->getWeek() do not match current // year and week number, meaning that there are toplists in the // database, but not for current week // then: // create new toplist entity (for current week of current year) // else: // do nothing (return) if($last && $last->getYear() == $year && $last->getWeek() == $week) return; else { $new = new Toplist(); $new->setYear($year); $new->setWeek($week); $em->persist($new); $em->flush(); } This code is executed with each request to view toplist results (frontend) or list of toplists (backend). Anytime someone wants to access the toplist we first check if we should create a new toplist entity (for new week). 2) The question is: Is it possible that: User A goes to mydomain.com/toplist at 00:00:01 on Monday - the code should generate new entity the server slows down and it takes him 3 seconds to execute the code so new toplist entity is saved to database at 00:00:04 on Monday User B goes to mydomain.com/toplist at 00:00:02 on Monday at 00:00:02 there the toplist is not yet saved in database, thus UserB's request triggers the code to create another toplist entity And so.. after a few seconds we have 2 toplist entities for current week. Is this possible? How should I prevent this?
