Silverlight has a property on its animation timelines (like DoubleAnimation) called EasingFunction which allows you to specify a function with which to interpolate two values. Even though it's coming in .NET 4, I'd like to port this to 3.5. After reading this, it seems pretty doable, but I'm having a weird issue. I'm extending DoubleAni...

I have a list that the user can filter in several ways. two of which lend themselves to combo boxes and two that need to accept user input. For example, one textbox allows the user to type in any part of a list item's description, and the dialog will only present items whose description contains the text entered. It is a dialog 'picker'...

When each control is created, it is associated with a thread and consequently all activities associated with that control need to occur on that thread. We've got an application that has a large number of top-level windows, each with a host of controls within th...
