Microsoft has ramped up the security in their latest operating system – Windows Vista, which means that developers now have to pay more attention to certain security constraints imposed by the operating system when developing applications. Those of you readers who have read my prior posts on User Access Control in Vista (and the further reading [...]

Pass by Reference
Posted in Everything, Software Development, tagged C#, Code on October 25, 2006 | 2 Comments »
Contrary to the beliefs of some developers, .Net reference types do not need to be passed as reference parameters (ref in C#, ByRef in VB) when a method is going to alter the contents of an object instance. Passing a object reference by reference parameter just means the method can reassign the reference to a [...]

Access modifiers on property get/set
Posted in Everything, Software Development, tagged C#, Code on February 25, 2006 | 2 Comments »
To some I may be stating the obvious, but today I was happy to find out that C# lets you set a different access level on the get and set for a property. The example below will help to illustrate what I’m talking about: public DateTime UpdateDate { get { object data = ViewState["UpdateDate"]; return [...]
From C++ to C#
Posted in Everything, Software Development, tagged C#, Code on November 28, 2005 | 2 Comments »
I have gone back in time this week to work on a legacy ISAPI application. The ISAPI application is being developed in C++ and makes use of MSXML to read an XML configuration file. Below is some code in C++ to open the XML file and read two text values, contained in element nodes: BOOL [...]
Multicast Delegate Events as Properties
Posted in Everything, Software Development, tagged C#, Code on October 25, 2005 | Leave a Comment »
The saying goes “you learn something new every day”, and today is no exception. I’m not sure how I missed this, but never less, this post shows how to gain finer control over adding and removing of event handlers to public multicast delegate events. Typically, most C# developers are used writing event code as follows: [...]
C# 2.0 and the ‘yield’ keyword
Posted in Everything, Software Development, tagged C#, Code on September 13, 2005 | 6 Comments »
Another nice addition to C# 2.0 is the yield keyword. Yield enables iterator blocks to provide values to an enumerated result, see the following example. // yield-example.cs using System; using System.Collections; public class List { public static IEnumerable Power(int number, int exponent) { int counter = 0; int result = 1; while(counter++ < exponent) { [...]
Nullable Types in C# 2.0
Posted in Everything, Software Development, tagged C#, Code on August 30, 2005 | 2 Comments »
I was reading about Nullable Types in the C# 2.0 specification for the .NET Framework 2.0 today. I am surprised I didn’t find out about this feature long ago, goes to show that you learn something new every day. So what are Nullable Types? Simply put, Nullable Types are value types that a can be [...]
Firing multicast delegate events
Posted in Everything, Software Development, tagged C#, Code on August 17, 2005 | Leave a Comment »
I am currently writing an ASP.NET server control, which exposes a number of custom events. I was looking through my code archives for a helper class, which will safely call handler methods of a multicast delegate, when an event is triggered. I found the class I was looking for, and decided to publish it here [...]
Code Comments

I have lost count of the number of times that I have been asked to work on a piece of software written by another developer, only to find out that the code had no comments. What typically follows is hours spent wading through lines and lines of complex instruction to determine how the software was [...]
