There's a well-known anti-pattern called the anaemic domain model[1][2]. This anti-pattern basically says domain entities, chronically, have little or no behaviour (remember, object-oriented design is about attributes and behaviour). It should be...

Pass-through Constructors

Pass-through constructors is a term I use to describe parameterized constructors that have none of their own logic and simply pass parameters to the base class. For example: public class BaseClass { private String text; public BaseClass( String text)...

I had to implement some custom sorting in a DataGridView recently. Essentially, the stakeholders wanted full column selection (like Excel) while still having the ability to sort the data based on a particular column. This particular DataGridView is data...

DataGridViewColumn.Frozen

DataGridViewColumn.Frozen is documented as "When a column is frozen, all the columns to its left (or to its right in right-to-left languages) are frozen as well." Which is nice until you think of the consequences. The consequences being that...

Last post I detailed some code that may or may not have something wrong in it.  If you thought InitializeOne and IntializeTwo are semantically identical (e.g. they differ only by performance), you'd be wrong. If you simply ran the code, you'd...

Drag-copying in Visual Studio Solution Explorer.

NOTE: I've tried this in Visual Studio 2008 (VS2k8), I'm assuming the same thing happens in Visual Studio 2005 (VS2k5). In the process of refactoring, it's *very* common for me to rename a type. This is most easily done by renaming the file...

Nested Types

Recently Michael Features blogged about nested types . The title was almost "nested types considered harmful". I don't agree. I don't agree that they're any more harmful than any other C# construct (except goto...). Nested types...

Comparing CodeRush Refactor! Pro and Resharper 4, part 1 or N -- first glance.

Metadata view of code in referenced assemblies This is a big one for me. For whatever reason, Refactor 4 (and prior) completely disables this and sends you to the Object Browser instead. You get metadata view with CodeRush Refactor! Pro. Keyboard layout...
