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.
The Add Projects extension for Visual Studio has been updated to version 1.0.1.0, adding a filter option to make it easier to find specific projects in a long list.
The ColorPicker Controls have been updated to version 1.0.4.0.
This is a fairly substantial update, with quite a few bug fixes and enhancements to the code. I'll also briefly discuss plans for future updates to the library.
The ImageBox control is already a versatile little control and I use it for all sorts of tasks. One of the features I recently wanted was to allow users to be able to select a source region, then adjust this as needed. The control already allows you to draw a selection region, but if you need to adjust that ... well, you can't. You can only draw a new region.
This article describes how to extend the ImageBox to include the ability to resize the selection region. A older demonstration which shows how to drag the selection around has also been incorporated, in a more tidy fashion than the demo.
The second in a two part series that describes how to load and save Adobe Photoshop colour swatch files using C#. This second article provides a full example project that will write RGB and HSL based swatch files.
The first of a two part series which describes how to load and ultimately save Adobe Photoshop colour swatch files using C#. This first article describes the file format, and provides a full example project that will read RGB based swatch files.
I took a break from arguing with our GIF decoder to take a quick look at the BBM format as I have a few files in that format containing colour palettes I wished to extract. When I looked into this, I found a BBM file is essentially an LBM file without any image data, so I set to work at writing a new palette serializer for reading and writing the palette files. This article describes how to read the palettes from BBM and LBM files.
