I just realized I don't fully understand why in .NET you assign events using a += symbol. I figured this out yesterday when I needed to remove an event and without thinking I was doing someobject.onsomeevent += null thinking that would just remove the event I had previously assigned. After some investigation, I figured out I had to ...
I don't have an iPad yet to find this out; have had only a brief opportunity to look at one at the Apple store. Could someone please describe what, if anything, happens to the mouseOver event of an image-map area when the image-map|area has had user-select disabled with "webkit-user-select: none" in the CSS, as described here in section...
int epoll_wait(int epfd, struct epoll_event *events, int maxevents, int timeout); I'm a little confused about the maxevents parameter. Let's say I want to write a server that can handle up to 10k connections. Would I define maxevents as 10000 then, or should it be be lower for some reason? ...

Hi folks, I have a winforms c# app that has an embedded webbrowser control inside it generated through VS.NET 2008. We sink events by inheriting our events class from HTMLDocumentEvents2. public class IEHTMLDocumentEvents : mshtml.HTMLDocumentEvents2 { public bool onclick(mshtml.IHTMLEventObj pEvtObj) { // Clicki...

Hello, I stumbled upon a curious problem with MFC. I have a Dialog where I check every Edit field on ON_EN_KILLFOCUS if it's valid. If validation doesn't go through I set focus back and show error message. This would be fine, if only I would close the dialog. I mean if I leave wrongly entered field and press close button or X, then ON_E...
I'm developing a OPOS Service Object for fiscal printers. I came to implement the events. According to the Monroe documentation, the SO initiates events by calling an event request method exposed by the Control Object. So, as far I understand, in my SO I should declare and initialize the Monroe CO and to fire an event I should call the...

I am using the properties view in RCP, i.e org.eclipse.ui.views.properties.PropertySheet. I want to be able to refresh the content of these properties programmatically. It seems RCP is geared towards the use case where this changes only when a selection changes. Is there any way I can fire a dummy event to get this to refresh (without ...
I recognize this may be a duplicate post, but I want to make sure I ask this question clearly and get an answer based on my wording. I have a collection of forms which inherit from a common visual element: MainVisualForm. This element provides me a way to know when the form is advancing of stepping backwards. What form comes next in th...
I generate HTML using jQuery: $("<a />") .append("demo") .click(function () { DemoFunc(event, value.Id) }) This works perfect for Chrome and IE8, but in FireFox I got an error: "event is not defined". I changed the code like this: .attr("onclick", "DemoFunc(event, " + value.Id + ")") It works for Firefox, but not for Chrome...

Button and make that button when clicked call some of FootballPlayer functions eg. Run(). Is there any simple or complex, but clean way to achieve this kind of behaviour?

I'm writing a basic tic tac toe game in Java. In my Board class I have a swing window which determines which button was pressed. TttGame is the class which has a Board object. The goal of this board is not to act as a fully functional tic-tac-toe board but to serve as a framework where the TttGame class controls all the logic. As such...
Hi, In googling I can't seem to find an example of intercepting event on a proxied type and it doesn't seem to be working for me. Is there a way I can do this (ie. use an IInterceptor when an event is invoked)? Thanks. ...
In HTML5, the search input type appears with a little X on the right that will clear the textbox (at least in Chrome, maybe others). Is there a way to detect when this X is clicked in javascript or jQuery other than, say, detecting when the box is clicked at all or doing some sort of location click-detecting (x-position/y-position)? Tha...
Let's say I have a window-less application which has only an icon on the Taskbar (Windows, Mac OS X & Linux). I want it to capture some key & key combinations, let's say Right Control + Right Shift. Upon keying in correct, combination, it will do something, say take screenshot. I can do window-less app, icon on the Taskbar and screen cap...
In my GWT program I have a table that has a selected row. I'd like to move the row selection with the up- and down-keys on the keyboard. So I have to catch the key events somehow. The GWT docs handle key events in input fields only. But I don't have an input field! Is this possible at all? Maybe it is a DOM/Javascript restriction that ...
Hi all, maybe my design is not good, or I don't see the obvious solution, but I want to subscribe to a buttonClick EventHandler of Form1 from outside form1. For example I have a Controller and Form1 who are both instanced in the main function. Now I want to subscribe a function from Controller to the buttonClick event from Button1_Cl...
