Mixins are missing from C#. There are lots of examples of emulating mixins and some really good ideas. The best ideas assume the use of C# 4.0 and use the ConditionalWeakTable class. However none of the ideas I could find were truly generic. This post is about a generic mixins mechanism for .NET and provides [...]

ExtJS is a great JavaScript framework because it is comprehensive. The flip side is that it is huge. Because there’s no code completion facilities that work with ExtJS (don’t get me started on the waste of effort that is the Eclipse plugin) it’s necessary to remember lots of stuff which I find impossible. As a [...]

This post is my write up of the options to access data in a cross-domain scenario which maybe just to support the ability to develop on a machine in one domain and access data in another domain.

The announcement was a webcast shown at noon PDT and led by Steve Ballmer. However the interesting stuff was presented by Kirk Koenigsbauer who demonstrated Office 2013 [...]

ExtJS 4 is a great framework for creating rich internet application. However there is a big problem: it’s a huge productivity drain. Modern development tools are complete with features to help make the code writing experience as productive as possible. In particular, code completion. This post is about a project to add ExtJS code completion [...]

When using input gathered from a user to create a regular expression, the user input may contain regular expression control characters such as ‘.’ and ‘*’. These need to be escaped so the regular expression engine treats them as literal characters.

The JsonP proxy (Ext.data.proxy.JsonP) is provided to handle cross domain queries and posts. Using it is straight forward but just swapping out an ajax or json proxy and using a jsonp proxy is not enough.

Setting node values is straight forward when nodes are added manually. So how are node params set when a tree is loaded from a TreeStore? This Sencha forum post shows the fields which can be returned by a store to control the parameters of each node.
