This little script uses the JQuery getScript command, enforcing sequential loading order to ensure script dependencies are honoured: function LoadScriptsSequentially(scriptUrls, callback) { if (typeof scriptUrls == 'undefined') throw "Argument Error: URL array is unusable"; if (scriptUrls.length == 0 && typeof callback == 'function') callback(); $.getScript(scriptUrls.shift(), function() { LoadScriptsSequentially(scriptUrls, callback); }); } Here’s how you use [ READ MORE ]
I’ve recently been using PostSharp 1.5 (Laos) to implement various features such as logging, tracing, API performance counter recording, and repeatability on the softphone app I’ve been developing. Previously, we’d been either using hand-rolled code generation systems to augment the APIs with IDisposable-style wrappers, or hand coded the wrappers within the implementation code. The problem [ READ MORE ]
UPDATE: The original code for this post, that used to be available via a link on this page, is no longer available. I’m afraid that if you want to try this one out, you’ll have to piece it together using the snippets contained in this post. Sorry for the inconvenience – blame it on ISP [ READ MORE ]
I’ll start out with an apology – it was only by writing this post, that I worked out how to write a shorter post on the same topic. Sometime I’ll follow this up with something less full of digressions, explorations or justifications. The topic of the post started out as ‘Closure‘. It then became ‘Closure plus [ READ MORE ]
Recently, Søren Skovsbøll wrote a excellent follow up to a little post I did a while back on using C# 3.0 expression trees for representing predicates in design by contract. The conclusion of that series was that C# was inadequate in lots of ways to the task of doing design by contract. Having said that, you [ READ MORE ]
This is the second in a series on the basics of functional programming using C#. My topic today is one I touched on last time, when I described the rights and privileges of a function as a first class citizen. I'm going to explore Higher-Order Functions this time. Higher-Order Functions are functions that themselves take or return functions. Meta-functions, if you like[ READ MORE ]
