I would like someone to try and explain the difference between these. More specifically, example usage scenario's. I am refactoring some Windows Form code and a Form has some code in the Form_Load() event and also in a protected override void OnLoad() event that calls base.OnLoad(e); Now I traced it and the Override fires first and ...
I have a JTable which is bound to my EventTracker bean, essentially a wrapper around a list which I will use as append/clear only (i.e., a simple log). Problem is, when I add entries to the list and try to fire an event I don't see any changes. I'm using the NetBeans IDE. The EventTracker bean is added to the view and instantiated as ev...
Is there's a way to know, in javascript, if the page will change ? During an event (ie a click) is there a way to know what is the coming page without checking element's href (if clicking on a link) or form's action (if submitting a form) ? ...
I don't have access to this iframe's source directly, so I would like to do this, if it's possibly this way. I have an iframe generated by JS: <iframe name="temp_iframe" width="100%" height="95%" src="'+the_url+'"></iframe> And inside is a submit button and a cancel button. The submit button works fine, but I want the cancel button t...
Hello, I am building a Winforms application with drag and drop support into a TextBox. The TextBox should allow files and text to be dropped onto it. Its AllowDrop property is set to true.

I've got a weird slowdown in my ASP.NET website that I cannot seem to track down. I'm suspecting that GC might be kicking in and halting my threads. To know for sure it would be nice to log every time when GC does occur. I could make a dummy object and do the logging in its finalizer, but that would then be a one-shot solution, while in...

Im talking about two separate touches on the screen with the same finger I think i have the coding right for this. but it is almost impossible for me to actually generate a double tap on my iPad. Is it possible to increase the time interval between a single and double tap, so it is easier to trigger. I do a double tap very fast and it c...
YUI 3 just recently came out with touch event support for their slider, so that it can be manipulated using touch screens on mobile devices like iPhones and Android. However, it might be a while before there is a dual thumb slider (aka "range slider") made within the YUI 3 framework. Possibly it will take longer than the deadline for my...

Is there a way to get notified (e.g., by an event) when a Visual has been (re-)rendered? Basically, I would like to take a screen shot whenever a Visual's appearance has changed. I assume the rendering thread is taking care of this in the background. I am trying to avoid grabbing a screen shot periodically since I am only interested in...
This might be a stupid question but I write a class called test lets say in GWT and I want to have it listen for DOM events. How would I do that? I have tried implementing lets say the KeyPressHandler and then implementing the method onKeyPress() and I place an Window.alert("Event") in the body. Though nothing happens when I test it pre...
Which are, for every of the following methodology to implement an interface listeners, the pros and cons: 1) into the main class as: class MyClass implements ActionListener { public void actionPerformed(ActionEvent e) { // ... } component.addActionListener(this); } 2) as an inner class as class MyClass { pri...
Here's what I am working with: Part of my project is a windows form app. I want to basically capture every event that fires and has listeners. So some button's click event, some checkbox's check event, everything on a basic "Control" event list. So that event still fires, but also fires my event. Is there a generic "some event fired" ...
my C# winform application needs put itself in standby mode during time other application runs in true fullscreen mode (not only maximized), like video games, video movies, powerpoint. I need a method to detect if currently there is other application in fullscreen. Is there a possibility to register to events which will fire when other ...
I'm trying to do something rather simple but I'm getting a strange result. I have an event trigger that I'm using to pass a json object but when it gets through to the other side it's a function... I alert the result and it shows this: example of alert sting: alert('value of lattitude? ' + map.currentLatLng.lat); result: value o...
I have an event driven architecture where A is waiting for a change from B and B is waiting for a change from C and C is waiting for a change from A, forming a cycle. Now, if B changes, then A fires an event to C, which fires to B, which fires to A, which fires to C...ad infinitum. I can change my program right now to not contain thi...
In dotNET with C# 4.0, How can I ensure that event that happens on an arbitrary thread X will call handlers in the same thread (or synchronization context) as the subscribing thread A, B, or C. I am trying to avoid having to put in threading-related code into handler method or event site. It would be really great if I wouldn't have to ...
