The longer I program, the less tolerance I have for “magic strings”. You might be familiar with them – they are strings that have programmatic meaning but are trapped between quotes in another language.

A classic example is SQL held in a string variable within your C#/PHP/whatever code. It might just as easily be HTML in your Javascript.

The problem is that this code is meaningless outside of its domain. Your SQL server knows what SELECT means, but the PHP interpreter does not. If you misspell it, or generate it dynamically, and it fails, you are not going to know why. Cross your fingers!

Earlier this week I blogged about the availability of a patch on the Microsoft Download Center to fix the recent ASP.NET Security Vulnerability.

Today we also made it possible to update systems through Windows Update (WU) and Windows Server Update Services (WSUS).  This enables administrators to more easily streamline patch installs, and enables you to take advantage of the WU/WSUS infrastructure to detect which patches you should install based on what versions of .NET are on your system.

Please make sure to install these updates as soon as possible on your servers.  This will prevent attackers from using the vulnerability to attack your systems.

Using Windows Update

If you run Windows Update on your system you’ll see the security updates listed if you haven’t already installed them on your computer.  Note that you’ll see a separate update available for each version of .NET you have installed on your system:

Please make sure all of the “Security Update for Microsoft .NET Framework” updates are selected and then apply them to keep your system secure.

Final Product

As Richard Tape has begun to show in his part 1 and part 2 articles on Becoming an ExpressionEngine Superstar, EE is a flexible and easy to customize CMS. Now that everyone has some understanding of how EE works, I thought I would take this opportunity to show a relatively real world example of creating a dynamic Google Map powered by EE.

.NET LINQ from Scratch

As software developers, we spend a lot of time extracting and displaying data from many different data sources. Whether it’s a XML webservice of some sort, or a full featured relational database, we have been forced to learn different methods of data access. Wouldn’t it be great if the method of access was the same for all data sources? Well, we are in luck because, as of the release of C# 3.0 and the .NET 3.5 Framework, LINQ has come to change the game forever.

Tutorial Details

  • Introduction to LINQ syntax
  • Projections using LINQ
  • Refining data
  • Standard operators

Current Data Access Overview

On the .NET platform we have been and still are utilizing ADO.NET
for accessing different data sources. The open source community has also provided
the developers with a number of alternatives.

Since its release, ASP.NET applications and components have looked to the web.config file to load any settings they need to function. However, adding custom settings to add flexibility and robustness to an application or component isn’t as straight forward as most would like. This article teaches you how to write the necessary classes to handle XML configuration elements and use the settings they contain within your code.
