Using gacutil.exe and Reflection to generate the Exceptions Cheat Sheet

10 February 2010 07:28
The most recent addition to my Cheat Sheets features details of all the Exceptions that can be found in the most commonly used assemblies within ASP.NET development. Compiling this information was an interesting challenge. I could have simply copy-pasted from MSDN, but that would have been extremely tedious. Instead, I ended up with a blend of Linq to XML, Reflection, a dash of Regex and the Global Assembly Cache Tool - gacutil.exe. Here's the full story. More...

Cheat Sheet - .NET Framework Exceptions

Here's a list of Exceptions that can be found in the assemblies which are most commonly used in ASP.NET development. Ideally, you should be as specific as possible when catching or throwing Exceptions. The more specific you are, the less work the CLR has to do in locating the appropriate catch block, and the more informative your error messages are, which should help speed up identifying the source of any problems.

I got given jQuery In Action for Christmas. By nature, I'm kind of a late adopter, and I'm already regretting this fact. jQuery has been around for some time, and I wished I had looked at it sooner. It's a fantastic library that really simplifies Javascript development, and is already attracting a goodly number of plug-ins. JCrop is one such, and while it hasn't yet reached version 1.0, it is remarkably easy to use as a web based image cropper. Here's how to put jQuery, JCrop and a FileUpload control together to allow users to upload images and crop them. More...

Delegates, Anonymous Methods and Lambda Expressions in C#

Delegates in C# cause a fair amount of confusion, but with the introduction of LINQ to SQL and the profilic use of the Lambda Expression operator (=>) that it has foisted on an unprepared batch of beginners, an understanding of how these two items are related, together with Anonymous Methods becomes more important. Most definitions of Delegates that you find start off with comparing them to "function pointers in C or C++", which is great if you ever worked with those languages and understood them, but not helpful to new programmers. Here's my attempt at simplifying the various concepts. More...

Book Review - Beginning ASP.NET 3.5 in C# and VB

Over the years, I have picked up and read many Beginners books that attempt to get someone started on the road to building web sites with ASP.NET. Nearly all of them assumed that their readers know more than they might. Some of them seem to assume that all readers are upgrading from one version of the .NET framework to another, while others assume that you already know about core web development technologies such as HTML, CSS, C# or VB etc. I well remember being frustrated with my first book, in that it didn't give me enough basic information to get started with web development, let alone web development with ASP.NET. Now, up steps Imar Spaanjaars, with his effort: Beginning ASP.NET 3.5 in C# and VB (Wiley/Wrox, ISBN: 978-0-470-18759-3). More...

Using an ArrayList to cheat at Scrabble

My dad had a Facebook account. He was addicted to it. Or rather, he was addicted to the Scrabulous application, which is a Flash-based online version of the popular word game Scrabble. Trouble is, he kept beating me, and I had to do something rather drastic to corrrect that. So I thought it can't be too difficult to build a C# ASP.NET app that would give me some... err... assistance. Scrabulous offer the TWL06 (current official Tournament Word List) as a downloadable text file, so armed with a complete list of all 186,000+ legal Scrabble words, I sat down and started to think about how I could use it.
