  • Object drag delay issue

    - by Johnny Darvall
    I have this code that drags stuff around perfectly in IE - however in firefox the onmousedown-drag of the object does not immediately drag but shows the no-entry cursor and then after onmouseup the object drags around freely. The object does stop draging on the next onmouseup. The object should only drag in the onmousdown state, while the onmousup call should cancel the drag by making j_OK=0. I think it may have something to do with the image inside... the object: <em style=position:absolute;left:0;top:0;width:32;height:32;display:block> < img src=abc.gif onmousedown=P_MV(this.parentNode) style=position:absolute;left:0;top:0;width:inherit> </em> function P_MV(t) { p_E=t j_oy=parseInt(p_E.style.top) j_ox=parseInt(p_E.style.left) j_OK=1 document.onselectstart=function(){return false} document.onmousemove=P_MVy } function P_MVy(e) { if(j_OK) { p_E.style.top=(j_FF?e.clientY:event.clientY)-j_y+j_oy p_E.style.left=(j_FF?e.clientX:event.clientX)-j_x+j_ox } return false }

  • What makes for a good JIRA workflow with a software development team?

    - by Hari Seldon
    I am migrating my team from a snarl of poorly managed excel documents, individual checklists, and personal emails to manage our application issues and development tasks to a new JIRA project. My team and I are new to JIRA (and issue tracking software in general). My team is skeptical of the transition at best, so I am also trying not to scare them off by introducing something overly complex at the start. I understand one of JIRA's strengths to be the customized workflows that can be created for a project. I've looked over the JIRA documentation and a number of tutorials, and am comfortable with the how in creating workflows, but I need some contextual What to go along with it. What makes a particular workflow work well? What does a poorly designed workflow look like? What are the benefits/drawbacks of a strict workflow with very specific states and transitions to a looser workflow, with fewer, broader defined states and transitions

  • How do you handle measuring Code Coverage in JavaScript

    - by Dancrumb
    In order to measure Code Coverage for JavaScript unit tests, one needs to instrument the code, run the tests and then perform post-processing. My concern is that, as a result, you are unit testing code that will never be run in production. Since JavaScript isn't compiled, what you test should be precisely what you execute. So here's my question, how do you handle this? One thought I had was to run Unit Testing on the production code and use that for my pass fail. I would then create a shadow of my production code, with instrumentation and run my unit tests again; this would give me my code coverage stats. Has anyone come across a method that is a little more graceful than this?

  • What are examples of games with "minimalist" models/art assets

    - by Ken
    When teaching game development, my student's obsess about building realistic or complex art/models/animation. And spending wayyy to much time trying to get accurate collision detection between two 3D models [despite my best efforts] However I would like them to spend more time thinking about developing the game mechanics, interaction and game play. I'm looking for some games where the visuals are simple but have good game play. Things I am thinking about are Cubes' vs Spheres or Impossible Game. What are more examples of visually simple (preferably 3D) games to help inspire my students?

  • WPF ItemsControl - how to know when the items finished loading, so that I can focus the first one?

    - by Tomáš Kafka
    Hi everyone, I have an ItemsControl in my View, that is bound to an ObservableCollection from ViewModel. The collection is filled, and afterwards an event from VM to view is raised (think search results and SearchFinished event). I would like to move keyboard focus to the first item in an ItemsControl, but when I do it in View's code-behind when handling SearchFinished, the items are not yet rendered (the collection is filled already, but wpf's rendering is asynchronous and didn't happen yet), so there is nothing to focus (Focus() needs to have the items' visual tree already constructed). I wanted to do (myItemsControl.ItemContainerGenerator.ContainerFromIndex(0) as UIElement).Focus();, but as the 0th item is not yet loaded, ContainerFromIndex(0) returns null. I tried delaying it with Dispatcher.BeginInvoke... with low priority, but that is dependent on exact timing and usually doesn't work. How can I wait until the first item in ItemsControl is Loaded?

  • Flash Hates Me. Error #1009: Cannot access a property or method of a null object reference

    - by sol
    I simply create a movie clip, put it on the stage and give it an instance name of char. Here's my document class, simple as can be: public class Test extends MovieClip { public function Test() { char.x = 1315; char.y = 459; addEventListener(Event.ENTER_FRAME, mouseListen); } private function mouseListen(e:Event) { char.x = mouseX; char.y = mouseY; } } And I get this error: TypeError: Error #1009: Cannot access a property or method of a null object reference. at com.me::Test/::mouseListen() How in the world is it possible that it knows what "char" is in the constructor but not in the mouseListen function? What else could it be?

  • Should data structures be integrated into the language (as in Python) or be provided in the standard library (as in Java)?

    - by Anto
    In Python, and most likely many other programming languages, common data structures can be found as an integrated part of the core language with their own dedicated syntax. If we put LISP's integrated list syntax aside, I can't think of any other languages that I know which provides some kind of data structure above the array as an integrated part of their syntax, though all of them (but C, I guess) seem to provide them in the standard library. From a language design perspective, what are your opinions on having a specific syntax for data structures in the core language? Is it a good idea, and does the purpose of the language (etc.) change how good this could be of a choice? Edit: I'm sorry for (apparently) causing some confusion about which data structures I mean. I talk about the basic and commonly used ones, but still not the most basic ones. This excludes trees (too complex, uncommon), stacks (too seldom used), arrays (too simple) but includes e.g. sets, lists and hashmaps.

  • Add child to scene from within a class.

    - by Fecal Brunch
    Hi, I'm new to flash in general and have been writing a program with two classes that extend MovieClip (Stems and Star). I need to create a new Stems object as a child of the scene when the user stops dragging a Star object, but do not know how to reference the scene from within the Star class's code.

  • Organazing ASP.Net Single Page Application with Nancy

    - by OnesimusUnbound
    As a personal project, I'm creating a single page, asp.net web application using Nancy to provide RESTful services to the single page. Due to the complexity of the single page, particularly the JavaScripts used, I've think creating a dedicated project for the client side of web development and another for service side will organize and simplify the development. solution | +-- web / client side (single html page, js, css) | - contains asp.net project, and nancy library | to host the modules in application ptoject folder | +-- application / service (nancy modules, bootstrap for other layer) | . . . and other layers (three teir, domain driven, etc) . Is this a good way of organizing a complex single page application? Am I over-engineering the web app, incurring too much complexity?

  • How to recover data from NTFS partition that was made into a Swap partition?

    - by Raghav Mehta
    I have extremely important stuff on my windows partition which during the ubuntu 10.10 installation,when it said that I should create something called swap space, I selected it to be a swap space (without even knowing what it actually meant) The Grub2 doesn't show up so I don't get a choice to boot Ubuntu or Windows. I don't get my windows partition as a removable device in Ubuntu either. When I go to disk utility and select the sda2 (i.e.. my windows partition) and click edit partition and select HPFS/NTFS for the type and tick bootable and click OK the small processing sign keep on rotating on the bottom right of the sda2 in the chart and after about 10 to 15 minutes it gives an unknown error and thus, I am still unable to use my windows. I am even worse than a beginner who doesn't know a thing about Ubuntu so please be patient and help me out.

  • Get the caret position when losing focus in WPF

    - by DrLazer
    I have two textbox's. I have an event setup for the "onLostFocus" of the textbox's. If i finish typing a word into both boxes one after the other all is well. At the point where i click back on the first textbox i want to click halfway through the word (perfectly resonable thing for a user to do). When the onLostFocus event fires here is my code : void tbox_LostFocus(object sender, RoutedEventArgs e) { IInputElement focusedelement = FocusManager.GetFocusedElement(this); if (focusedelement is TextBox) { TextBox focusedTextBox = focusedelement as TextBox; int focusIndex = m_commandsStacker.Children.IndexOf(focusedTextBox); int caretIndex = focusedTextBox.CaretIndex; The caret index is 0. At that point I refresh the whole form and set parameters and all other kinds of whizzery, storing the texbox index and caret position to put everything back the same. Why does it return 0 and not the position where the caret should be halfway between the word?

  • Is there a way to install Ubuntu stripped down without desktop applications?

    - by Nick Berardi
    Just to start off, I know of lubuntu but it really doesn't meet what I am looking for. Basically what I am looking for is the standard Desktop Ubuntu install, but with out all the word processing, multimedia, and games installed. I have seen posts out about how to get the desktop environment running on Ubuntu server, but they seem complicated, and never seem to equal the standard Desktop install. So my question is, is there anyway to tell the standard Desktop install not to install all the applications? Or is there a distro available that leaves all the applications out, and just has the standard desktop look and feel? What I really want this for is, is for development purposes to run on a VM to do Mono development.

  • Best practice Java - String array constant and indexing it

    - by Pramod
    For string constants its usual to use a class with final String values. But whats the best practice for storing string array. I want to store different categories in a constant array and everytime a category has been selected, I want to know which category it belongs to and process based on that. Addition : To make it more clear, I have a categories A,B,C,D,E which is a constant array. Whenever a user clicks one of the items(button will have those texts) I should know which item was clicked and do processing on that. I can define an enum(say cat) and everytime do if clickedItem == cat.A .... else if clickedItem = cat.B .... else if .... or even register listeners for each item seperately. But I wanted to know the best practice for doing handling these kind of problems.

  • Sharing Authentication Across Subdomains using cookies

    - by Jordan Reiter
    I know that in general cookies themselves are not considered robust enough to store authentication information. What I am wondering is if there is an existing design pattern or framework for sharing authentication across subdomains without having to use something more complex like OpenID. Ideally, the process would be that the user visits abc.example.org, logs in, and continues on to xyz.example.org where they are automatically recognized (ideally, the reverse should also be possible -- a login via xyz means automatic login at abc). The snag is that abc.example.org and xyz.example.org are both on different servers and different web application frameworks, although they can both use a shared database. The web application platforms include PHP, ColdFusion, and Python (Django), although I'm also interested in this from a more general perspective (i.e. language agnostic).

  • Where can I find simple, but well-written programs to learn from?

I can sort of piece together what a specific snippet of code does, but I quickly lose the context of what I'm looking at and how it fits in. I want to be able to improve, but everything I've tried learning from so far has been too big. Where can I find well-written, but not very complex source code to look at? edit: Sorry, to be more specific, I'm hoping for javascript/php/C#.

  • Ordering the calling of asynchronous methods in c#

    - by Peter Kelly
    Hi, Say I have 4 classes ControllerClass MethodClass1 MethodClass2 MethodClass3 and each MethodClass has an asynchronous method DoStuff() and each has a CompletedEvent. The ControllerClass is responsible for invoking the 3 asynchronous methods on the 3 MethodClasses in a particular order. So ControllerClass invokes MethodClass1.DoStuff() and subscribes to MethodClass1.CompletedEvent. When that event is fired, ControllerClass invokes MethodClass2.DoStuff() and subscribes to MethodClass2.CompletedEvent. When that event is fired, the ControllerClass invokes MethodClass3.DoStuff() Is there a best practice for a situation like this? Is this bad design? I believe it is because I am finding it hard to unit test (a sure sign) It is not easy to change the order I have an uneasy, code-smell feeling about it What are the alternatives in a situation like this?
