I am aware of the KeyPreview property of a Windows Form, and this allows the Form to receive the key events before they get passed to the focused control. However, I want the Form to receive the event after it has been to the focused control. As a test I have placed a TextBox on a Form. Upon typing in the TextBox it should perform it's...
Let's say I have a "Processor" interface exposing an event - OnProcess. Usually the implementors do processing thus I can safely subscribe on this event and be sure it will be fired. But one processor doesn't do processing - thus I want to prevent subscribers to subscibe on it. Can I do that? In other words in the code below I want the l...
I understand how to use Events according to Net Framework guidelines, but what are the benefits of using this pattern? http://msdn.microsoft.com/en-us/library/aa645739%28VS.71%29.aspx : The .NET Framework guidelines indicate that the delegate type used for an event should take two parameters, an "object source" parameter indic...
Here is specifically what I am seeking to accomplish: Using .Net 3.5, I have a Windows Service, within which I have a WCF Service running. I have a client, which requests a file from the WCF Service (Net.Tcp binding), which is then copied by the WCF service to a specified location, where it can then be edited/modified by the client. The...
I come from the world of web programming and usually the server sets a superglobal variable through the specified method (get, post, etc) that makes available the data a user inputs into a field. Another way is to use AJAX to register a callback method to an event that the AJAX XMLhttpRequest object will initiate once notified by the bro...

Is there a way to bind an event handler to a double click with jQuery instead of single click? ...
I'm building an application using EXT for GWT (i.e. GXT). In GXT, every component that can be added to a page has an associated Render event that can be captured and handled. Due to some limitations I need to step down to pure GWT for a small portion of my application. Specifically, I want to modify the RichTextArea widget by adding s...
Related to my previous question. Is there a way to block the subscription in compile time? Something like marking the event's "Add" as "private" in the implementor even though it's public in the interface. ...
I need to detect when a user arrives at the end of a readonly textarea in an html page. The textarea will display a very long log for an application. The logs files are so big that is impossible to load all the text in one time (some log files are almost 200 MB). So I will load the first, say, 1000 lines, and then I need to detect when ...
I have UserControls within UserControls in WPF. This makes a tree structure starting from the root node. I want to register for the event MouseLeftClickDown in all the UserControls. Left Clicking on a child control causes the event to fire for that control and all the parent controls that contain that child. When I click a child, I do...
I'm trying to programmatically send modified keystrokes, for instance a capital "A". The problem is that the shift modifier does not seem to have any effect. In my code, I have two events, one for the shift key down, and another for the 'm' key down. CGEventRef mDown = CGEventCreateKeyboardEvent(NULL, (CGKeyCode)46, true); CGEventRef ...
Hi all, I want to write a history component that tracks changes to a particular object type and writes history rows based on the difference. Note this is not a general audit system it is specific for one object type. I figure I can hook into the hibernate event model and listen for events that tells me when things have changed, watch ...
Hi, I have a class which provides a custom event: public delegate void ResultEvent(bool result); public class Service : INotifyPropertyChanged { public event ResultEvent Result; } Two other objects have a refernce to this like this: public partial class SomeRandomClass { private Service service; public SomeRandomClass(...
Was just thinking about this question while trying to figure out some code written by our previous developer. Trying to trace out how control of the program was happening reminded me of the bad old days of BASIC, where it was hardly ever obvious the execution path of a program. Is this more a symptom of event abuse, or is there a struc...

I am working on an Outlook extension that requires making a change to a MailItem open in a compose window if the SendUsingAccount property is changed via the GUI. I would like to be albe to apply my changes automatically, but I cannot find any events that are raised when the user makes the change. I have tried listening to the followin...
New to GWT here... I'm using the UIBinder approach to layout an app, somewhat in the style of the GWT Mail sample. The app starts with a DockLayoutPanel added to RootLayoutPanel within the onModuleLoad() method. The DockLayoutPanel has a static North and a static South, using a custom center widget defined like: public class BigLayou...
I have code like this: setTimeout(foo, 600); I always thought that foo didn't take any arguments, e.g.: function foo() { /* bars */ } However, doing the following: function foo(a) { alert(a); /* bars */ } Popped up an alert displaying -7. What does this number represent? ...
