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
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.
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.

The ColorPicker Controls have been updated to version 126.96.36.199.
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.
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.

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.
