  • var in C# - Why can't it be used as a member variable?

    - by David Neale
    Why is it not possible to have implicitly-typed variables at a class level within C# for when these variables are immediately assigned? ie: public class TheClass { private var aList = new List<string>(); } Is it just something that hasn't been implemented or is there a conceptual/technical reason for why it hasn't been done?

    - by Faery
    Sorry for the noobie and stupid question, but I know only a bit about css and I don't know how to style my site. Here is my code: HTML (Twig) : <div class="wrap"> <div> <img class="birthday" src="http://www.clker.com/cliparts/1/d/a/6/11970917161615154558carlitos_Balloons.svg.med.png"> <div class="try"> This friends have brithday today: {% for bd in birthdays %} <p> <a href="{{ path('friend_id', {'id': bd.id}) }}">{{ bd.name }}</a> <span class="years"> ({{ bd.years }} years) </span> </p> {% endfor %} </div> </div> </div> CSS: body { background-color: #FFFFF1; text-align: center; font-size: 17px; font-family: Tahoma, Geneva, sans-serif; } p { margin: 10px; } a { text-decoration: none; color: #6a9211; } a:hover { text-decoration: underline; } .wrap { width: 700px; margin: auto; } .birthday { width: 49px; height: 80px; float: left; margin-left: 150px; display: block; } .try { display: block; margin-right: 150px; margin-bottom: 50px; } .years { font-size: 12px; } And this is what I get. The thing I want to fix is Maria and Peter to be display under Anna and John, all of them 4 centered under the label This friends have birthday today:. I know that it's because of the image, but I don't know how to make it look fine. :( Please help! Thanks in advance!

  • Grails Domain.get() returns null for mongo's ObjectId

    - by Shashank Agrawal
    I'm using grails 2.3.5 with mongodb 3.0.1 and no hibernate installed. I've a domain class which uses mongo's ObjectId. import org.bson.types.ObjectId class Category { ObjectId id String name } And has a record in mongo database: { "_id": ObjectId("53f6c34c33a429240e2ab471"), "name": "art", "version": NumberLong("41") } When I do, Category.get(new ObjectId("53f6c34c33a429240e2ab471")) somewhere in grails app, it returns null but when I do Category.get("53f6c34c33a429240e2ab471") it then actually returns the result. Why, get() method does not process ObjectId type?

  • Few doubts regarding Bitmaps , Images & `using` blocks

    - by imageWorker
    I caught up in this problem. http://stackoverflow.com/questions/2559826/garbage-collector-not-doing-its-job-memory-consumption-1-5gb-outofmemory-exc I feel that there is something wrong in my understanding. Please clarify these things. Destructor & IDisposable.Dispose are two methods for freeing resources that are not not under the control of .NET. Which means, everything except memory. right? using blocks are just better way of calling IDisposable.Dispose() method of an object. This is the main code I'm referring to. class someclass { static someMethod(Bitmap img) { Bitmap bmp = new Bitmap(img); //statement1 // some code here and return } } here is class I'm using for testing: class someotherClass { public static voide Main() { foreach (string imagePath in imagePathsArray) { using (Bitmap img1 = new Bitmap(imagePath)) { someclass.someMethod(img1); // does some more processing on `img1` } } } } Is there any memory leak with statement1? Question1: If each image size is say 10MB. Then does this bmp object occupy atleast 10MB? What I mean is, will it make completely new copy of entire image? or just refer to it? Question2:should I or should I not put the statement1 in using block? My Argument: We should not. Because using is not for freeing memory but for freeing the resources (file handle in this case). If I use it in using block. It closes file handle here encapsulated by this bmp object. It means we are also closing filehandle for the caller's img1 object. Which is not correct? As of the memory leak. No there is no scope of memory leak here. Because reference bmp is destroyed when this method is returned. Which leaves memory it refered without any pointer. So, its garbage collected. Am I right? Edit: class someclass { static Bitmap someMethod(Bitmap img) { Bitmap bmp = new Bitmap(img); //can I use `using` block on this enclosing `return bmp`; ??? // do some processing on bmp here return bmp; } }

    If I have a base class Base thing = null; of which there is a subclass class Subclass extends Base and I instigate it as thing = new Subclass how would I call a method that is specifically in Subclass, but not in Base? ex. Base has only method() Subclass has method() and specialMethod() the method specialMethod() is the one I want to call.

  • Soap Web Service PHP

    - by James Radford
    Is it possible to send a complexType to a SOAP web service by creating the complexType locally, i.e. create the type by creating a class and then sending the instance of that class back to the service? Admittedly this is only possible if I can get the definition of the type from the service provider. I'm looking to send a complexType back to a web service. So if this approach wont work please suggest an alternative...

  • jquery buttons icons for dialog

    - by khinester
    I have this code: $(function() { var mainButtons = [ {text: "Invite" , 'class': 'invite-button' , click: function() { // get list of members alert('Invite was clicked...'); } } // end Invite button , {text: "Options" , 'class': 'options-button' , click: function() { alert('Options...'); } } // end Options button ] // end mainButtons , commentButtons = [ {text: "Clear" , 'class': 'clear-button' , click: function() { $('#comment').val('').focus().select(); } } // end Clear button , {text: "Post comment" , 'class': 'post-comment-button' , click: function() { alert('send comment...'); } } // end Post comment ] // end commentButtons $( "#form" ).dialog({ autoOpen: false , height: 465 , width: 700 , modal: true , position: ['center', 35] , buttons: mainButtons }); $( "#user-form" ) .button() .click(function() { $(this).effect("transfer",{ to: $("#form") }, 1500); $( "#form" ).dialog( "open" ); $( ".invite-button" ).button({ icons: {primary:'ui-icon-person',secondary:'ui-icon-triangle-1-s'} }); $( ".options-button" ).button({ icons: {primary:'ui-icon-gear'} }); }); // Add comment... $("#comment, .comment").click(function(){ $('#comment').focus().select(); $("#form").dialog({buttons: commentButtons}); $( ".post-comment-button" ).button({ icons: {primary:'ui-icon-comment'} }); $( ".clear-button" ).button({ icons: {primary:'ui-icon-refresh'} }); }); //Add comment // Bind back the Invite, Options buttons $(".files, .email, .event, .map").click(function(){ $("#form").dialog({buttons: mainButtons}); $( ".invite-button" ).button({ icons: {primary:'ui-icon-person',secondary:'ui-icon-triangle-1-s'} }); $( ".options-button" ).button({ icons: {primary:'ui-icon-gear'} }); }); // Tabs $( "#tabs" ).tabs(); $( ".tabs-bottom .ui-tabs-nav, .ui-tabs-nav > *" ) .removeClass( "ui-widget-header" ) .addClass( "ui-corner-bottom" ); }); ? What is the right way to add the button icons? As in my code I had to add it two times, once: $( "#user-form" ) .button() .click(function() { $(this).effect("transfer",{ to: $("#form") }, 1500); $( "#form" ).dialog( "open" ); ... and $(".files, .email, .event, .map").click(function(){ ... Could this code be improved further? I don't seem to be able to get the "transfer" effect to work correctly in a modal. I added: , close: function() { $(this).effect("transfer",{ to: $("#user-form") }, 1500); } to the $( "#form" ).dialog({ How would you go about in getting the "transfer" to work nicely when you open and close the dialog box?

  • Hide jQuery Accordion while loading

    - by zac
    I am testing a site build with a slow connection and I noticed the jQuery Accordion stays expanded for a long time, until the rest of the site is loaded, and then finally collapses. Not very pretty. I was wondering how I could keep it collapsed through the loading process and only expand when clicked. I am working with the standalone 1.6 version of the accordion plugin. The basic structure : <div class="sidebar"> <ul id="navigation" class="ui-accordion-container"> <li><a class="head" href="#">1</a> <ul class="sub"> <li><a href="#">1a</a></li> <li><a href="#">2a</a></li> </ul> </li> </ul> </div> and the script jQuery().ready(function(){ jQuery('#navigation').accordion({ active: 'false', header: '.head', navigation: true, animated: 'easeslide', collapsible: true }); }); I tried to hide the elements in the CSS to keep them from appearing while loading but all that achieved is in having them always hidden. Maybe the problem is in the CSS I have a background image in each of the sub menus: #navigation{ margin:0px; margin-left: 10px; padding:0px; text-indent:0px; font-size: 1.1em; width:200px; text-transform: uppercase; padding-bottom: 30px; } #navigation ul{ border-width:0px; margin:0px; padding:0px; text-indent:0px; } #navigation li{ list-style:none outside none; } #navigation li ul{ height:185px; overflow:auto; } #navigation li ul.sub{ background:url('../images/sub.jpg') no-repeat; dispaly: block; } #navigation li li a{ color:#000000; display:block; text-indent:20px; text-decoration: none; padding: 6px 0; } #navigation li li a:hover{ background-color:#FFFF99; color:#FF0000; } Thanks in advance for any advice on how to have this thing run a little smoother and having the accordion always collapsed. -edit - I forgot to mention that I am also hoping for a solution that will allow the nav to still be accessible for those without javscript.

  • Multi-threaded Pooled Allocators

    - by Darren Engwirda
    I'm having some issues using pooled memory allocators for std::list objects in a multi-threaded application. The part of the code I'm concerned with runs each thread function in isolation (i.e. there is no communication or synchronization between threads) and therefore I'd like to setup separate memory pools for each thread, where each pool is not thread-safe (and hence fast). I've tried using a shared thread-safe singleton memory pool and found the performance to be poor, as expected. This is a heavily simplified version of the type of thing I'm trying to do. A lot has been included in a pseudo-code kind of way, sorry if it's confusing. /* The thread functor - one instance of MAKE_QUADTREE created for each thread */ class make_quadtree { private: /* A non-thread-safe memory pool for int linked list items, let's say that it's * something along the lines of BOOST::OBJECT_POOL */ pooled_allocator<int> item_pool; /* The problem! - a local class that would be constructed within each std::list as the * allocator but really just delegates to ITEM_POOL */ class local_alloc { public : //!! I understand that I can't access ITEM_POOL from within a nested class like //!! this, that's really my question - can I get something along these lines to //!! work?? pointer allocate (size_t n) { return ( item_pool.allocate(n) ); } }; public : make_quadtree (): item_pool() // only construct 1 instance of ITEM_POOL per // MAKE_QUADTREE object { /* The kind of data structures - vectors of linked lists * The idea is that all of the linked lists should share a local pooled allocator */ std::vector<std::list<int, local_alloc>> lists; /* The actual operations - too complicated to show, but in general: * * - The vector LISTS is grown as a quadtree is built, it's size is the number of * quadtree "boxes" * * - Each element of LISTS (each linked list) represents the ID's of items * contained within each quadtree box (say they're xy points), as the quadtree * is grown a lot of ID pop/push-ing between lists occurs, hence the memory pool * is important for performance */ } }; So really my problem is that I'd like to have one memory pool instance per thread functor instance, but within each thread functor share the pool between multiple std::list objects.

  • Did Java invent interfaces?

    - by Jordão
    I know about C++ pure virtual classes, but Java went one step further and created a first-class (no pun intended) concept for multiple-interface (not implementation) inheritance, the interface. It's now a staple of major statically-typed languages. Did Java invent the interface concept? Or did it appear in older languages also as a first-class concept?

  • Asynchronous Delegates Vs Thread/ThreadPool?

    - by claws
    Hello, I need to execute 3 parallel tasks and after completion of each task they should call the same function which prints out the results. I don't understand in .net why we have Asychronous calling (delegate.BeginInvoke() & delegate.EndInvoke()) as well as Thread class? I'm little confused which one to use when? Now in this particular case, what should I use Asychronous calling or Thread class? I'm using C#.

    I have done some computer graphical programming recently, and I have no experience before. I used the library call CGAL(computer geometry algorithm library). Also, I noticed that there is class for triangulation and also class for mesh. Is mesh just a kind of triangle net? Do they have any differences? Thanks!

  • opacity in ie using absolutely positioned divs not working

    - by camomileCase
    I've been banging my head against the wall for a few hours how trying to sort this out. I'm trying to position one div on top of another for the purpose of fading one in on top of the other. The divs will have an image and some other html in them. I cannot get opacity to work in ie8. I've simplified my html as much as possible: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <style> * { margin: 0; padding: 0; } .carousel-container { position: relative; } .carousel-overlay { position: absolute; } #carousel-container-a { opacity: 1; -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)"; filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=100); } #carousel-container-b { opacity: 0; -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)"; filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=0); } h1 { font-size: 100px; } </style> </head> <body> <div id="carousel-container-a" class="carousel-container"> <div class="carousel-overlay" style="left: 10px; top: 10px;"> <h1 style="color: black;">Showcase</h1> </div> <!-- other elements removed for simplicity --> </div> <div id="carousel-container-b" class="carousel-container"> <div class="carousel-overlay" style="left: 20px; top: 20px;"> <h1 style="color: red;">Welcome</h1> </div> <!-- other elements removed for simplicity --> </div> </body> </html> Why doesn't the opacity work? How can I make it work?
