event-handling

I have a list of products, where I need to update the innerHTML of a #container dynamically. My question is, if I do something like in this answer: Jquery Remove All Event Handlers Inside Element $("#container").find("*").off(); So, I remove all the event handlers for all the children, and then I update the html: $("#container").html(responseFromAJAX); How will this affect on the performance? I mean, is this a good way, to remove all the old elements and handlers, and clean up memory, or I need to do more? My app is a webshop, so my Users will look around, and update the #container maybe 30-50

I am trying to register to a "Device added/ Device removed" event using WMI. When I say device - I mean something in the lines of a Disk-On-Key or any other device that has files on it which I can access... I am registering to the event, and the event is raised, but the EventType propery is different from the one I am expecting to see. The documentation ( MSDN ) states : 1- config change, 2- Device added, 3-Device removed 4- Docking. For some reason I always get a value of 1. Any ideas ? Here's sample code : public class WMIReceiveEvent { public WMIReceiveEvent() { try { WqlEventQuery query =

Is there any way to log All other Registered Event handlers when an event handler gets registered? Also Is there any way to log All Events emitted, and name of handler functions that gets triggered in when an event gets emitted during runtime? If the nodejs application triggers chained events (one event triggering another ) and each event has multiple handlers, when exception occurs at leaf of event-handler-chain, stacktrace does not show complete information of the context. Event log and handler info would be quite useful in such a situation. One hackey solution is to add (conditional)

My Problem I'm writing a PowerShell script that will need to download several large files from a remote web server before carrying on with other tasks. One of my project requirements is to show the progress of each download so the end-user knows what's going on. A response to another SO question contained a solution which uses registered events and Net.WebClient.DownloadFileAsync . However, when I try the solution in the accepted answer, the download is completing long before my script has handled all of the DownloadProgressChanged events. What I've Tried I've created a test script which I've

i am using AutoCompleteTextView in my Activity and i need it's DropDownList to be shown all the time (it's the only View in Window), even after Back key press. I need to dismiss soft keyboard instead. I tried to override Activity's onBackPressed method, but it's not used at all, so BackPressed event is being handled somewhere "higher". So i tried to find out where, but AutoCompleteTextView has no onBackPressed method defined. Any advices? You can create your custom AutoCompleteTextView and Override the method onKeyPreIme(int keyCode, KeyEvent event) I also realized that this method is called 2

I am trying to convert Java libs to c# libs. I am stuck at a place and could not find any solution via googling. The issue is in c# Class Lib i want to write assembly load/init event handler, is it possible as in Java it seems is? In java the code is. public class abc implements ServletContextListener { public void contextInitialized(ServletContextEvent event) { //do something } public void contextDestroyed(ServletContextEvent event) { //do something } } what would be its equivalent in c#? There is an AssemblyLoad event in the AppDomain class that may be what you are looking for: private void

This example makes it possible to click a legend and thereby change a plot. I want to do something similar, but then not by clicking the legend, just by clicking the line in the plot. I tried to do it like this: self.ax = self.fig.add_subplot(1,2,1) data = NP.array(2,10) #filled with numbers self.x = NP.arange(2) for line in range(len(data[0,:])): self.ax.plot(self.x, data[:,line], picker=5) In every loop, an extra line is plotted. One line consists of 2 points, so it draws a straight line. But now every loop, the picker is the same, so no matter which line I click, the commands I wrote to
