  • d3.behavior.zoom jitters, shakes, jumps, and bounces when dragging

    - by BrettonW
    I am using the d3.behavior.zoom to implement panning and zooming on a tree layout, but it is exhibiting a behavior I would describe as bouncing or numeric instability. When you start to drag, the display will inexplicably bounce left or right until it just disappears. The code looks like this: var svg = target.append ("g"); ... svg.call (d3.behavior.zoom() .translate ([0, 0]) .scale (1.0) .scaleExtent([0.5, 2.0]) .on("zoom", function() { svg.attr("transform","translate(" + d3.event.translate[0] + "," + d3.event.translate[1] + ") scale(" + d3.event.scale + ")"); }) ); Am I doing something wrong?

  • How to capture the value change of numericUpDown ctrl real-time in .NET?

    - by Carlos_Liu
    I have implement the ValueChanged event, but I found it will be triggered only after change the focus from numericUpDown to other control or by clicking the up/down arrow. Inputting the value in the control will not trigger ValueChanged event. What I did now is adding an KeyDown event and judge if the input value is numeric (can not include SHIFT/CTRL/ALT key); but there is another case need to be involved: the user can paste value into the numericUpDown ctrl What I need is : When I was typing numeric value (only numeric) in the numericUpDown ctrl, it will known the content has been changed; When pasted a numeric value into the ctrl, it also kowns the content changed

  • Adding mouse events to dynamically loaded SWF

    - by Josamoto
    I am loading an external SWF using the Loader class, and adding it to the stage with addChild. When trying to add a mouse click event listener to the MovieClip, using addEventListener, nothing happens, the event never fires. Is there a specific way to add listeners to externally loaded movie clips? My code looks somewhat like this: var target:MovieClip = assets["screensaver"] as MovieClip; target.root.addEventListener(MouseEvent.CLICK, onClickScreenSaver, true); addChild(target); The target shows up on the display, but the CLICK event is completely ignored.

  • jQuery mobile swipe spamming and animation

    - by halliewuud
    I have say 5 list items with images inside placed 200px from eachother. I am trying to animate these list items to slide horizontally left if one presses a link with the id = #next or if one swipes left. And vice versa for sliding the list items right. Every click or swipe results in a slide animation of 200px on every list item. I ran into a problem where spamming the #next or #prev button would cancel the current animation and start a new one. This results in list items not sliding 200px+200px+200... but something like this 200px+140px+120... This because like I said the animation is cut and therefore the sliding distance will be shorter. Now I solved this for the clicking event by disabling the button before the animation starts and then re'enabling it on the end callbak function. But this problem is remaining for the swipe event. How can I solve this problem for the swipe event?

  • The Darkness Behind DateTime.Now

    DateTime.Now is one of the commonly-used properties in the .NET Framework in the majority of applications designed. Although this property is designed to serve for particular purposes, the lack of understanding and training has driven many .NET developers to use it in wrong circumstances where other options like DateTime.UtcNow property and Stopwatch class should be used and are recommended. In this article we discuss these three options along with the main applications of each, and provide a quantitative comparison between them to show why DateTime.Now is expensive and should not be misused in many cases.

    - by kevinb92
    Hello, I want to hide and show some form in my page. For each form theres a link, and i want that, when i click on this link, it hide and show the nearest form of the link. My code looks like this : $$('.flagLink').each(function(s){ $(s).observe('click', function(event) { // here i want to hide and show the nearest form }); }); I've tried this : $$('.flagLink').each(function(s){ $(s).observe('click', function(event) { $(s).next('form').toggle(); }); }); It works but, i would like to be more precise like : $$('.flagLink').each(function(s){ $(s).observe('click', function(event) { $(s).next('.flagForm').toggle(); }); }); but the .flagForm selector doesnt work.

  • Error in vb.net windows service when connecting to SQL

    - by Clint
    I've installed a vb.net windows service on a Windows 2008 machine, that is attempting to connect to SQL 2005. The service starts succesfully, but can't see the database. The event log has the following entry. The description for Event ID 0 from source SU4.ESMR.DAL.Job.FillPriorityJobByType(oJobDS, TypeID: 3 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. This was tested locally on both XP and 2008. All environments are 32 bit.

  • Update NSView in function of events

    - by Forchita
    Hi everyone! I have a main view (subclass of NSView) and as i'm new to cocoa, i'd like to know how to update the view in function of events. I know there are many methods that take events such as -(void)mouseMoved:(NSEvent*)event or - (void)mouseClicked:(NSEvent*)event My algorithm to determine what to do is ready. I want to know where I should update the main view: is it in the -(void)mouseMoved:(NSEvent*)event or in the - (void)drawRect:(NSRect)dirtyRect. And if it is in drawRect, then how should i pass the information to it? Thanks in advance!

  • Why 80 Per Cent of the Links Your Have Built Will Disappear in 6 Months

    However scary this may read, it's true, and contrary to the feelings that the title of this article may have created, this is actually a blessing in disguise for those who have been involved with "value driven" SEO strategies. The days of scrounging the net for links from every website/ community possible is over. Webmasters and SEO experts who have been following such strategies will find that most of the links they are building are getting removed from search indexes every couple of months.

  • Delegates vs. events in Cocoa

    - by aaronstacy
    I'm writing my first iPhone app, and I've been exploring the design patterns in Cocoa and Objective-C. I come from a background of client-side web development, so I'm trying to wrap my head around delegates. Specifically, I don't see why delegate objects are needed instead of event handlers. For instance, when the user presses a button, it is handled with an event (UITouchUpInside), but when the user finishes inputting to a text box and closes it with the 'Done' button, the action is handled by calling a method on the text box's delegate (textFieldShouldReturn). Why use a delegate method instead of an event? I also notice this in the view controller with the viewDidLoad method. Why not just use events?

  • python win32api registery key change

    - by user340495
    Hi, I am trying to trigger an event every time a registry value is being modified. import win32api import win32event import win32con import _winreg key = _winreg.OpenKey(_winreg.HKEY_CURRENT_USER,'Control Panel\Desktop',0,_winreg.KEY_READ) sub_key = _winreg.CreateKey(key,'Wallpaper') evt = win32event.CreateEvent(None,0,0,None) win32api.RegNotifyChangeKeyValue(sub_key,1,win32api.REG_NOTIFY_CHANGE_ATTRIBUTES,evt,True) ret_code=win32event.WaitForSingleObject(evt,3000) if ret_code == win32con.WAIT_OBJECT_0: print "CHANGED" if ret_code == win32con.WAIT_TIMEOUT: print "TIMED" my problem is that this is never triggered , the event always time-out. (the reg key I am trying to follow is the wallpaper) [ please note I trigger the event by 1) manually changing the registry value in regedit 2) an automated script which run this : from ctypes import windll from win32con import * windll.user32.SystemParametersInfoA(SPI_SETDESKWALLPAPER, 0,"C:\wall.jpg",SPIF_UPDATEINIFILE | SPIF_SENDWININICHANGE) ] Thanks for any help in advance :) EDIT:: sorry about formatting

  • How to make HTML5 speech recognition not ask permission every time

    - by user2081044
    I have created a script that requires my microphone. It uses the HTML5 speech recognition API. Chrome asks permission every time I want to perform a speech recognition test. Javascript (partial) code that I am using: var recognition = new webkitSpeechRecognition(); recognition.continuous = true; recognition.interimResults = true; recognition.onresult = function(event) { console.log(event.results[0][0].transcript); if(event.results[0][0].transcript === 'print') { console.log(''); } }; recognition.start(); I have tried to add it into the list of exceptions in either Chrome and Flash player, but it still asks for permission. Printscreen: That message pops up everytime I click the button. Is there any way to disable Chrome for asking permission?

  • null pointer exception on list.add

    - by Eric
    I've been working on this one error for a few hours so I thought I'd pick the brains of some pros. I am getting a null pointer exception at the modelData.add(i, es) method. I know from debugging that es isn't null. I'm really confused, thanks. public class EventTableModel extends AbstractTableModel { //private int rowCount = 0; protected List<EventSeat> modelData; private static final int COLUMN_COUNT = 3; private Event e; Event j = GUIpos.m; int i = 1; public EventTableModel(Event e) { this.e = e; try { System.out.println(modelData); for (EventSeat es : e.getEventSeats()) { modelData.add(i, es); i++; } } catch (DataException ex) { Logger.getLogger(EventTableModel.class.getName()).log(Level.SEVERE, null, ex); } }

  • Get list of running processes, get active process (and it's application) Flex/AIR

    - by Adam Kiss
    Hello, just a quickie (or maybe not:] ): Is it possible to get somehow list of running applications/processes and, while running in background, check which process is active? Additionally - if somehow, the answer was yes, is it possible to react for change of active window / application react just as if it was Event, or bind to it custom event (e.g. Event.SystemActiveAppChange)? Thank you for answers as well as pointers. EDIT: Due to probable missunderstanding, I mean local applications - on your win/mac/linux machine - I would like to (in process of learning of language) track what apps I use the most, make a little graph maybe? So, the point is: in AIR app, developed in FLEX, I would like to get/list all running applications/processes, as well as which one is active (on user's PC/Mac/Linux)
