I have around 10 buttons on my form and I want them to call the same Click event handler. But for that I need the Event handler to be generalized and we don't have "this" keyword in VB.NET to refer to the control that caused the event. How do I implement the functionality of "this" keyword in VB.NET? I want to be able to write an Even...

Detect windows logout in Java

Is there a library that I can use with Java to listen for user logout and possibly other Windows events? (Even better if it supports multiple platforms!) I remember reading about a library of this sort a number of years ago, but can't seem to find it now. I've seen other threads to do essentially the same thing using Python with win32...

C# How to trigger an Control.Resize event without actually resizing?

See the title. This should be really easy, but i don't quite see how to actually do it. (Update) I'm not subclassing the control. Trying to trigger the event via Control.Size = Control.Size fails, since it does not trigger then even unless the new size is actually different. ...

What is the "Weak Event" pattern used in WPF applications?

The WindowsBase DLL defines the IWeakEventListener event with summary: Provides event listening support for classes that expect to receive events through the WeakEvent pattern and a System.Windows.WeakEventManager.

Re-dispatching event in FLEX

In a FLEX app, I am trying to "re-dispatch" a custom event. I.e. component1 does dispatchEvnet(event), component2 registers a handler for the event, the only function of the handler being, again, dispatch(event). Finally, component3 listens for the event coming out of component2. What I am trying to do is similar to the concept of "re-th...

using jQuery after someone else's Javascript

Scenario: I have a Javascript-generated web page that someone else wrote a long time ago that I'd like to pretty up using jQuery. My goal is to clean up the Javascript generated html that someone else produces just by using some jQuery calls against that HTML, after it has been generated. This will be much simpler than modifying the ot...

How built-in WPF controls manage their event handlers to an attached event ?

I know that when you register an object to the mouse's attached events, you have memory leaks. That's why you need to use WeakEvent pattern. I have a problem with this pattern : If you want to use it, you cannot define your handler in the XAML code. To me, it means that every code like this leaks : <SomeControl Mouse.MouseDown="MyHand...

Does Application.ApplicationExit event work to be notified of exit in non-Winforms apps?

Our code library needs to be notified when the application is exiting. So we have subscribed to the System.Window.Forms.Application.ApplicationExit event. This works nicely for Winforms apps, but does it also work for other types of applications such as console apps, services, and web apps (such as ASP.NET)? The namespace would suggest...

In Dojo or Javascript how do I make my event handler fire before other event handlers?

In the Dojo Javascript library, I understand how to use dojo.connect or dojo.publish to wire up my event handler to an event. That functionality works great. But I want to do one additional thing.
