This post is a review (or possibly some long winded rambling) of the book Essential Algorithms: A Practical Approach to Computer Algorithms by Rod Stephens and published by Wiley.

The ColorGrid control is a fairly useful control for selecting from a predefined list of colours. However, it can take up quite a bit of screen real estate depending on how many colours it contains. This article describes how you can host a ColorGrid in a standard ToolStrip control, providing access to both the ColorGrid and the ColorPickerDialog, with some custom painting to show the active colour on the button to round it off.
Following on from last years post, I'll list again what I'm using and seeing what (if anything) has changed.
tl;dr; - it's pretty much the same as last year
The process of obtaining a code signing certificate from StartSSL differs significantly from the process I originally went through with Comodo. This blog post serves to document how I did it for StartSSL, both as a reference for myself and for anyone else! Personally I find this approach easier than fiddling around exporting certificates from a browser, and it gives you a lot more control.
I was recently using a ComboBox control with the DropDownStyle set to Simple, effectively turning into a combined text box and list box.
However, when I wanted an action to occur on double clicking an item in the list I found that the control doesn't actually offer double click support. I suppose I should have just ripped out the combo box at that point and went with dedicated controls but instead I decided to extend ComboBox to support double clicks.
In my last post, I described how to drag and drop items to reorder a ListView control. This time I'm going to describe the exact same technique, but this time for the more humble ListBox.
I can't remember when it was I first saw something being dragged with an insertion mark for guidance. Whenever it was, it was a long long time ago and I'm just catching up now.
This article describes how to extend a ListView control to allow the items within it to be reordered, using insertion guides.
Occasionally I need to embed HTML in my applications. If it is just to display some simple layout with basic interactions, I might use a basic component that doesn't need the weight of Internet Explorer. In most cases however, I need a more complex layout, JavaScript or I might want to display real pages from the internet - in which case I'm lumbered with the WebBrowser control.
This control annoys me in myriad ways, but it does get the job done. One of the things that occasionally frustrates me is that by default it is essentially an embedded version of Internet Explorer 7 - or enabling Compatibility Mode in a modern IE session. Not so good as more and more sites use HTML5 and other goodies.
This article provides a helper class to easily set the browser emulation version from your C# applications.
A brief article which describes how to create a definition ruleset to allow better Batch/Command style formatting in the DigitalRune/SharpDevelop Text Editor control.
An overview of the generic CircularBuffer class. CircularBuffer is a data structure that uses a single, fixed-size buffer that behaves as if it were connected end-to-end. You can use it as a first-in, first-out collection of objects with automatic overwrite support and no array resizing or allocations.
