Evolving code over time

Given economics, time constraints, resource limitations, etc.; you can't write all the functionality for a given solution for a single release. Even if you weren't limited by these constraints, you're likely to get changing requirements as development progresses and everyone learns more about...

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) { this .text = text; } } public class DerivedClass...

.NET 4.0, Evolving .NET Development

.NET 4.0 is the first release of .NET since 2.0 that evolves .NET for every programmer. .NET 3.0 was largely LINQ and .NET 3.5 was largely new namespaces (like WCF, WWF, etc.) .NET 4.0 evolves the programming and design for any programmer. It offers framework support for parallel processing (PFX will...

Becoming a Visual Studio Jedi Part 1

Becoming a Visual Studio 2008 (and often Visual Studio 2005) Jedi In much the same grain as James' Resharper Jedi posts, I'm beginning a series of posts on becoming a Visual Studio Jedi. It involves getting the most out of Visual Studio off-the-shelf, doing things as quickly as possible and with...

Trials and Tribulations of DataGridView, Column Selections, and Sorting

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-bound. DataGridView offers the Sort(DataGridViewColumn...

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 freezing a column and all columns to the left is...

ITSWITCH #1: Answer

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 be able to guess where the problem is. ...

ITSWITCH: #1

Is There Something Wrong In This Code Here UPDATE: as several readers pointed out there was compile error in the code what was being displayed. The line "String value = string" was showing up as "String value = string". I'm not sure why; but throwing some spaces between the i...

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 are like anything else in our tool-belt: they have...

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 As you might imagine, CodeRush Refactor! Pro and...

Entity Framework Petition of Vote of Non Confidence

I had intended to be happy simply being a signatory of ADO .NET Entity Framework Vote of No Confidence. But, there's people suggesting signatories of this petition are wackos or on the fringe. Do yourself a favour and read the petition . Read what we have issues with and how we think Entity Framework...

Spaces or Tabs?

In this day and age it seems silly to get into a discussion about whether your companies coding guidelines should have a section mandating either spaces or tabs for indents. Tabs are clearly more flexible, but I really don't think it matters at all; people can easily read code that contains spaces...

Overcoming problems with MethodInfo.Invoke of methods with by-reference value type arguments

I ran into an interesting problem on the Forums recently. Basically, when you use MethodInfo.Invoke to invoke a method with by-reference value type arguments you can't have the invoked method update a variable/argument. The problem is, when you invoke the method the parameter is passed to the MethodInfo...

Licences for Microsoft products

Occasionally I get development questions that are governed by one or more product licenses (End-User License Agreement, "EULA"). One question that I see is "I've used Reflector to decompile the .NET Framework and want to use that C# code in my application". You've installed...

Single-Entry, Single-Exit, Should It Still Be Applicable In Object-oriented Languages?

Before the modern high-level languages Edsger Dijkstra came up with "Structured Programming". This programming methodology relied on the programmer to form and enforce most of the structure of the program--manually keeping sub-structures and logic separate from one another to promote maintainability...

"Object is currently in use elsewhere" error.

I was debugging what I thought was a strange exception the other day. The exception was an InvalidOperationException and the message was "Object is currently in use elsewhere". Unless you're familiar with this exception, it really doesn't offer much as to why the exception is occurring...

Formatting/parsing for a specific culture redux

In recent blog post I detailed how creating a culture via the CultureInfo constructor could actually create a user-overridden culture--which could be completely different than the culture that you've requested by name. Fortunately there's a way of overriding the user override (apologies for overloading...

Formatting/parsing for a specific culture

Sometimes you may want to use a specific format for formatting and parsing of textual data. The easiest way to do this is to select a specific culture and use that with formatting and parsing methods. Unfortunately, the CultureInfo constructor that just takes the name of the culture defaults to accepting...
