  • Flex - Use Variables for Object Attribute Names

    - by Immanuel
    How do you use variables to access Object attributes? Suppose I have an Object declared as follows, var obj:Object = new Object; obj.Name = "MyName"; obj.Age = "10"; How would i do something like this, var fieldName:String = "Name"; var fieldAge:String = "Age"; var Name_Age:String = obj.fieldName + " ," + obj.fieldAge; The code above treats 'fieldName' and 'fieldAge' as attribute name itself. I want to treat the same as a variable, and map the value associated with the variable as the Object attribute name.

  • Find and list all functions/methods in a set of JavaScript files

    - by Dan Milstein
    Is there a way to read a set of JavaScript files, and output a description of where every function/method is defined? I realize that this is likely impossible in full generality, due to the extreme dynamic nature of the language. What I'm imagining is something which gets the (relatively) straightforward cases. Ideally, I'd want it figure out where, e.g. some method got attached to string or hash or some other fundamental class (and also just let you find all the classes/functions that get defined once in one place). Does such a tool exist?

  • How to force calling of QWidget::paintEvent() when its hovered by other window?

    - by Pie_Jesu
    Hi there. I have occured a problem: I'm writing a widget, which displays current date's day number. It's like a button, but it's not derived from QPushButton class. Just from QWidget. So I reimplemented enterEvent(), leaveEvent(), mousePressEvent(), mouseReleaseEvent(). I call update() inside these methods and widget has realistic button behavior (paintEvent() is reimplemented too). But when I change system date and hover that widget with other window, my widget doesn't calls paintEvent() and displays old date. Only when I place mouse over it, widget repaints it's contents. I guess there is an option, which paints old contents on hover event to avoid unnecessary paint events. But I need to disable it. Tried to set many attributes (Qt::WidgetAttribute enum). But it doesn't helps. Please, help me (and sorry for my bad english).

  • Multiple row insertion in a faster way

    - by Cyborgo
    Hi, I am using rails and I am trying to insert new rows into the table. The data comes from a text file and I created hash with one of the attribute as key. Then I find all the keys that are currently not in the table. Then I need to insert all of them into the table with all the attributes that I saved in hash. newvals.each{ |x| author = Author.create(:first => x, :second => hash[x][0], :third => hash[x][1]) author.save } This has lot of overhead as it makes an SQL update one at time. The newals array is usually quite big around the size of 20-30k. I know create can insert multiple objects at once, but I cant seem to figure out how. Is there any way to get this done. Thanks.

  • Rails subscription limitations

    - by David Lyod
    I have an application with set limits on subscription attributes i/e a user can have five projects for subscription A but have ten for subscription B At present I run a check on there current usage when linking to the create action and if they are over there limit I do not display the link to create a new project. On the view (for the new project ) I again run the check (in a helper) to see if they can create a new project and if they are not I display a message stating so and a little upgrade link. Is this a secure method of stopping a user bypassing there subscription attribute limitations ? What about direct PUT requests etc ?

  • Having two backgrounds for an active menu item?

    - by HollerTrain
    Hi I have a dynamic menu where the ul li items change in width depending on the text set in the CMS (Joomla). They want the menu item, on mouse over, to both have 1. a repeated background image and 2. an image placed at the top (http://screencast.com/t/Zjk4YTJmNGQ). Now, I'm great with doing the repeated background image on a mouse over and that would be great, but I am not sure how to get both of these images in one css declaration. Any help would be greatly appreciated, as I haven't learned this technique yet :(

  • generating an objectForKey from an array

    - by Brian
    I'm having success when I use this code to get a string from an array of file names called "fileList": cell.timeBeganLabel.text = [[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]; so I expected the same code to generate the same string as a key for me in this: NSDictionary *stats = [thisRecordingsStats objectForKey:[[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]]; cell.durationLabel.text = [stats objectForKey:@"duration"]; or this: NSDictionary *stats = [thisRecordingsStats objectForKey:@"%@",[[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]]; Both build without error, and the log shows my data is there: but I'm getting a blank UILabel. Have I not written the dynamic key generator correctly?

  • Please help me get my content div to get an auto height from absolutely positioned element

    - by Justin Hollender
    I need some help with a CSS layout. It is set up like this: +--------------------+ | | | header | |-| |--------------| | |nav| content | | | | | | | | | | | | | | footer | +--------------------+ So, the nav is supposed to be floating above all the main page content. That's why I have it set to be absolutely positioned. The issue is that the nav items are dynamic, without a set height. Right now, the nav expands past the content. How can I fix it so that the content will have an auto height based off the nav? Thanks in advance.

  • Symfony 2 form repeated validation in Entity with annotation

    - by Sukhrob
    My question is "How can I do form repeated validation in Entity with annotation?". I have an Account entity with (email, password and confirmPassword) attributes. When a new user registers a new account, he/she has to fill in email, password and confirmPassword fields. Obviously, password and confirmPassword fields must match. I saw an example of this validation with pure php (form builder) in Stachoverflow like below. $builder->add('password', 'repeated', array( 'type' => 'password', 'first_name' => 'Password', 'second_name' => 'Password confirmation', 'invalid_message' => 'Passwords are not the same', )); But, this is not what I want. I want this functionality with annotation in my Account entity. Maybe * @Assert\Match( * matchField = "password", * message = "The password confirmation does not match password." * ) protected $confirmPassword;

  • Android png images big in memory

    - by taivo
    i have an application in android that has an imageflipper. Problem is, after about 8 images loaded to memory, i get an out of memory error. Well, i tried to do dynamic image loading, so that if the user flips 2 images, i'll load next 2 to memory and delete 2 first ones. It kind of works, but it ugly and i have trouble when user flips images back(imageflipper.showprevious()), i can't really shift all images and place new images to the beginning. My question is, is there a better way to do this kind of stuff? Resizing images didn't really help.

  • "Refreshing" an XML feed on iPhone/Mac OSX

    - by Steve
    Hi all, I'm curious for those of you who are building iPhone apps based on REST/SOAP/XML-RPC or simply pulling down a dynamic XML feed, what does it mean exactly to you when a user says 'refresh' the feed? The straight forward way is to populate some collection, say an NSMutableArray, with whatever you bring down from the feed. If a widget on the UI is available to refresh, I typically do something like: [myMutableArray removeAllObjects]; // follow steps to repopulate myMutableArray It seems this is the least efficient algorithm for refreshing an XML feed. For instance many folks who are building Twitter clients, are appending changes to their existing feed, versus bringing down the entire feed in its complete form again. What kind of algorithms are you using to "refresh" your models when speaking to a server-side data source? Thanks all.

  • .NET security mechanism to restrict access between two Types in the same Website project?

    - by jdk
    Question: Is there a mechanism in the .NET Framework to hide one custom Type from another without using separate projects/assemblies? I'm using C# with ASP.NET in a Website project (Note: Not a Web Application). Obviously there's not a way to enforce this restriction using language-specific OO keywords so I am looking for something else, for example: maybe a permission framework or code access mechanism, maybe something that uses meta data like Attributes. I'm unsure. I don't really care whether the solution actually hides classes from each other or just makes them inaccessible, etc. A runtime or design time answer will suffice. Looking for something easy to implement otherwise it's not worth the effort ... Background: I'm working in an ASP.NET Website project and the team has decided not to use separate project assemblies for different software layers. Therefore I'm looking for a way to have, for example, a DataAccess/ folder of which I disallow its classes to access other Types in the ASP.NET Website project.

    How many methods/ways are there taking input by using with pointer and dynamic memory? Input: 3 1 2 n k l 2 1 2 p 4 55 62 * # x (x is stop value, first input always integer) Example code: p=malloc(sizeof(int)); scanf("%d",&num_arrays); while(1) { scanf("%c",&(*(p+i))); if(*(p+i)=='x') break; ++i; } "3" is stored in num_arrays. The other input values are stored in pointer[array].

  • Is it possible to auto generate Getter/Setter from Array Values in PHP?

    - by Phill Pafford
    So I have a couple of arrays $array_1 = Array('one','two','three'); $array_2 = Array('red','blue','green'); Is there a dynamic way to create the Setters and Getters for an array with single value entries? So the class would be something like: class xFromArray() { } So the above if I passed $array_1 it would generate something like this: private $one; setOne($x) { $one = $x; } getOne() { return $one; } if I passed $array_2 it would generate something like this: private $red; setRed($x) { $red = $x; } getRed() { return $red; } So I would call it somehow like this? (My best guess but doesn't seem that this would work) $xFromArray = new xFromArray; foreach($array_1 as $key=>$data) { $xFromArray->create_function(set.ucfirst($data)($data)); echo $xFromArray->create_function(get.ucfirst($data)); }

  • Can two different versions of the same libs (with same name) exists in an application?

    - by Jay
    I have some scenario like this: Product- Platform- mylibs(version-1) Product- mylibs(version-2) i.e Product uses mylibs (version-2) directly. Product also uses platform (which is also a dynamic lib) and platform uses my libs (version-1). The names of the libs used by product and platform are same. Only versions are different and both these versions are not compatible. Is there a way with ".so" libs in linux that Platform can link to one version and product can link to another version of the same libs having the same name?

  • Are UIView's in TableViewCells cause for performance problems?

    - by iFloh
    Hi, I have a UITableView of UITableViewCells that so far performed well. I now aded a simple UIView to my UITableViewCell as a color indicator (backgroundColor only, no other content or attributes). Running the tableview again I realise scrolling is not as smooth as it used to be. The tableView suddenly also takes long time (~1+ secs) to come back again when returning from a subview (e.g. return from the view that gets pushed upon selection of a cell). Any ideas why the added UIView would be problematic? Why are the labels (being a subclass of UIView) not cause for similar issues?

  • dynamically double image size

    - by Edan Duarte
    I have an embarrassingly simple question: How can I display an image at double its size without hard coding the width and height attributes? Here's what I tried, but I ended up having to just enter 1000 for width and height. Is something wrong with my function? Thanks! <img onload="double(self.id);" name="bigPic" id="bigPic" src="album1.jpg" height="1000" width="1000"/> function double(id) { var img = document.getElementById(id); var dblWdth = img.width * 2; var dblHt = img.height * 2; img.height = dblHt; img.width = dblWdth; }

  • MySql query and table optimisation

    - by Cheeky
    Hi everyone. I am trying to run the following simple query on a table with 500K records. SELECT COUNT(*) AS impressionCount FROM impression WHERE 0 = 0 AND impressionObjectId1 = 'C69A54B8-B828-E2E4-2319A93011DF4120' AND impressionObjectId2 = '1'; This query is taking 10 seconds to run. I have tried creating individual indexes for the impressionObjectId1 and impressionObjectId2 columns, as well as a composite index using both. The composite worked well for a while, but now it is also slow. Here is my table structure: DROP TABLE IF EXISTS `impression`; CREATE TABLE `impression` ( `impressionId` varchar(50) NOT NULL, `impressionObjectId1` varchar(50) NOT NULL, `impressionObjectId2` varchar(50) default NULL, `impressionStampDate` datetime NOT NULL, PRIMARY KEY (`impressionId`), KEY `IX_object` (`impressionObjectId1`,`impressionObjectId2`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 ROW_FORMAT=DYNAMIC COMMENT='InnoDB free: 191488 kB'; Any advice would be greatly appreciated. Thanks EDIT: When adding an EXPLAIN, this is the output: 1, 'SIMPLE', 'impression', 'ref', 'IX_object', 'IX_object', '105', 'const,const', 304499, 'Using where; Using index'

  • should a student be diversifying or mastering programming languages?

    - by Max Link
    As the question states, is it better if a student diversifies or explores when learning programming languages or should they focus only on 2-3 languages and really get to know them well? Example of what I mean by diversifying: Functional -> Scheme Procedural -> C Object Oriented -> Java Dynamic or scripting -> Python Other -> C++ I have a few breaks in between semesters sometimes (up to 3 months) and I'm thinking of either learning a new language or "master" those that I know right now. Which would benefit me in the future? I know some(about 3 months of self studying each) Java, C, and C++ already . If I'm not mistaken, where I live, the industry is heavy on Java, C++, and C#.

  • jQuery variable iteration with .each()

    - by user1143357
    My code needs to capture the 'src' of an image in a variable. It then needs to insert this variable into a 'href' tag on a link which surrounds the image. My code is as follows: $('.fancybox-image-li img').each(function(test) { var test = $(this).attr("src"); $('.fancybox-image-link').attr('href', ''+test+''); }); Unfortunately what seems to be happening is the 'test' var is only getting the attribute of the last img and then inserting this into all the 'href' attributes. Any ideas how I can get the variable to change per image. Cheers!
