I have an asp page that uses jQuery ajax to load member counts into a bunch of divs after a page is loaded. It works perfectly well in FireFox, and with clients that have a small number of groups. For the small number of clients that have many groups (500+), I am getting an error in IE. The ajax calls seem to be running synchronously,...

I'm trying to understand the event system of Kohana. The only thing i don't understand is, where to place the Event::add code. It should be in a place where it is executed before any events are fired. Or am I missing something? What i want to achieve is to construct a class that is available everywhere, but don't realy want to hack i...
I would like to know if there is a jQuery event that I can use to determine when a particular DIV's "Top" property has changed. For instance, I have invisible content above a DIV. When that content becomes visible the DIV is shifted down. I would like to capture that event and then use the offset() function to get the X/Y coordinates....
I'm working on an extension (BHO) for Internet Explorer, and having trouble attaching a .NET delegate to the mshtml objects to catch DOM events. I've tried using the events published by the IHTMLElementEvents2_Event, ... interfaces, and that works, but only if I specify the correct type for the DOM element whose events I want to catch. ...
I have made a C# application and I am trying to figure out if I can tap into build events of cctray (cruise control tray)? I don't want to re-invent the wheel, I just want to know when my builds fail or succeed (on a client machine) so than my custom C# application may execute a specific set of routines. ...

Hi all, I am new to UserControls, and while developing my own control I found a problem with showing events of my control in the property grid at design time. If I have some events in my control I want to see them in Property grid and if I double-click that I want to have a handler, in the same way Microsoft does for its controls. ...
I am developing an application trying to employ the Observer pattern. Basically I have a base form from which various components (forms) can be loaded. The base form references each of the components and some of the components reference each other. If I want one of the components to listen for events raised by the base form (perhaps fr...
I would like to ensure that I only subscribe once in a particular class for an event on an instance. For example I would like to be able to do the following: if (*not already subscribed*) { member.Event += new MemeberClass.Delegate(handler); } How would I go about implementing such a guard? ...
Hey, i'm extending some WPF controls, and need to implement some custom events. I've read around about the 'event' keyword and method groups, but im not sure how to implement this in code. Would anyone be able to provide a simple example of a custom event/handler/etc? Thanks! ...
Hello, I want to make a very simple event bus which will allow any client to subscribe to a particular type of event and when any publisher pushes an event on the bus using EventBus.PushEvent() method only the clients that subscribed to that particular event type will get the event. I am using c#.net 2.0 Any help/pointer would be grea...

I'm researching a bug that looks like some kind of timing issue and so I'm a bit curious about how events work in Delphi 7. What happens is we get some data sent to our application through a COM interface and it gets handled in an event raised from the COM thread. It seems like the event, which has quite a bit of code in it, takes longer...
In the javadoc it says that EventListener is "A tagging interface that all event listener interfaces must extend." Why is that? What's the significance of making a custom listener implement EventListner? Is there any special handling for EventListner somewhere? ...
I am adding dynamically controls to page by using LoadControl and Controls.Add. I need somehow to wrap Init and Load event handlers of this loaded controls into my code. So it should be such order of events SomeMyCode() -> Control.Init() -> AnotherMyCode() and the same for Load SomeMyCode() -> Control.Load() -> AnotherMyCode(). My idea w...
I have a ListBox displaying some items, and in certain modes I "stamp" a kind of watermark across the top of it. I've done this with a Border containing a TextBlock with an Opacity of 0.5. All this works nicely. However, I still want the user to be able to click on the items in the ListBox but if I click on the "stamp" it obviously eats...

For example: DateTimePicker dtpLastConsummated; i want to trigger the TextChanged event handler for the dtpLastConsummated, how can i do it? In other languages i would call something akin to: dtpLastConsummated.TextChanged(this, new EventArgs()); but in .NET you can ...
Is it safe to assume that event subscribers are called in order of subscription? Example: void One(object sender, EventArgs e) {} void Two(object sender, EventArgs e) {} event EventHandler foo; foo += One; foo += Two; Is One() always called before Two() when the event is fired? Edit: You should ofcourse not rely on it, I was just...
