Working with the MVVM pattern, I have a pair of view model classes that represent a two-tier data hierarchy, each with a corresponding UserControl that represents its view. Both view model classes implement INotifyPropertyChanged and the root level view model exposes a property that is relevant to both its own view and the child view. T...
Ruby's eval() can be like def showblock(&block) puts eval("i * 3", block) end where block is the block passed into the function. Instead of a block, a binding object can be passed in as well. Is the binding object the same as what is called the "scope chain" that is mentioned a lot when Javascript closure is discussed? ...

Hey guys, I would like to map my "WASD" to the arrows. I don't like moving my hands around. I already fixed it for my editor by calling W for arrowUp. But, how can I bind it for the entire system? When I call W, I want it to call the arrow UP. I can't bind those keys one software at the time. Any ideas? Thanks. -hbt ...
I have an ItemsControl that displays a bunch rectangles. Each rectangle needs to be offset upward and to the left. So, I created a RectangleStyle that uses bindings to set the width, height, X translation, and Y translation for a rectangle.

I'm using AvalonDock to layout my application. I want to create a "View" MenuItem with a checkable MenuItem for each of my DockableContents that will show/hide each item. I'm not finding an example of anyone doing this, and it appears to me the State property is readonly, making it not possible to create a 2-way binding to the MenuItem...
I would like to implement a virtual filesystem using FUSE under Linux and Mac OS X. I have mainly worked in Java and .NET/C#, but also familiar with Python and do write small utilities/shell scripts in Python. Writing is C/C++ is something that I would try to avoid if possible mainly because of lack of experience in the team. I see from...

Hello all, I've been using Castor these past couple of days to try to get a little serialization going between my Java program and XML in a readable way. Though it has a few faults, Castor's automatic xml generation via reflection is actually very functional. Unfortunately, one thing that seems to be fairly well left out of the exampl...

I want to bind a list of strings to ?. I know how to build the appropriate query-string manually, but I wonder if there is a way to do this with bindings. ...
I'm trying to implement a binding between some custom-built models and just beginning to dabble with the whole mx.binding.* collection. I tried this simple, stripped down example, but can't get the binding working correctly. Can somebody tell me where I'm going wrong? // Model package { import flash.events.EventDispatcher; public c...
I am new to both Haskell and programming. My question about binding in pattern-matched, recursive functions. For instance, suppose I have a function which checks whether a given list (x:xs) is a sublist of another list, (y:ys). My initial thought, following the examples in my textbook, was: sublist [] ys = True sublist xs [] = False sub...
