JavaScript bind() for cleaner code

Several weeks ago, I wrote about how closures impact calling asynchronous functions in a loop and several ways of dealing with that problem.

Let’s start with the easy one: server side code.

Overriding Events in VB.NET

Back in the day, you use to be able to override an event in VB by using the drop down list in the code window.  Today, I had a friend who is moving from Visual Studio 2003 to Visual Studio 2008 ask me, “How do I override events in VB.NET now?”  All you get in the drop downs now is the event handlers.
