• Keiki Usage Meter Version 3.2.1 Released

    Tonight I released Keiki Usage Meter Version 3.2.1. This release was prompted by Optus changing some things on their end that stopped the Optus Broadband (Legacy) plugin from working. There are some changes to the way tooltips, buttons, group boxes, combo boxes, radio buttons and check boxes are rendered, but nothing particularly noteworthy. I also […]

  • Warning: Simple Storage Spaces in Windows 8 can’t be dismantled

    A new feature in Windows 8 is ‘storage spaces’, a kind of software RAID, similar to the drive extender functionality found in the defunct Windows Home Server. Unlike Windows Home Server, however, Windows 8 provides no means of removing hard drives from simple (no resiliency) storage spaces, even when there’s adequate free space. Deleting the […]

  • Theme Colours in Windows ‘Blue’

    As I noted in my earlier post, the method for selecting theme (‘accent’) colours in Windows ‘Blue’ build 9364 has changed from Windows 8 RTM. I’m not going to bother looking too closely at the updates to the functions in UxTheme.dll this early in the development process, but I did notice two new registry values […]

  • Native Tooltips in WPF (Part 2)

    View source on GitHub. In part 1 of this article I looked at the differences between WPF tooltips and ‘native’ (Win32) tooltips. In this part I present a sample WPF application that displays native tooltips. I’d planned to walk through some of the code here, but that turned out to be a bit tedious, so […]

  • Windows ‘Blue’ Build 9364 Observations

    Update (2013-04-21): the thin borders are all gone in build 9374. It looks like Microsoft isn’t changing tack with the next release of Windows – the recently leaked build 9364 of Windows ‘Blue’ contains a bunch of worthwhile changes to the Modern/Metro/Immersive environment, but the desktop seems to be basically untouched from Windows 8. If […]

  • Native Tooltips in WPF (Part 1)

    View source on GitHub. <preamble> One of my hobbies is getting WPF controls to look more like their native counterparts. I’ve been shoehorning the UxTheme APIs (and older equivalents when theming is unavailable) into something that can be used by WPF over the past year or more, and I’ll write about this process at some […]

  • WPF ToolTip Drop Shadows in Windows 8

    The standard ToolTip control template for the Windows 8 theme in WPF (‘Aero2’) has no drop shadow, whether or not the HasDropShadow property is set. The background colour and margins are also slightly off compared to the native style. The following template produces a result that’s closer to the real thing: [crayon-63882bd608d9a740893869/] You’ll need to […]

  • SetDPI Utility Version 2

    View source on GitHub. A couple of years ago I made a small command-line program for setting the DPI/PPI of PNG files. I used the System.Drawing.Bitmap class (i.e. GDI+) to set this property, which had the unfortunate side effect of producing relatively bloated files. Given that the chunk specifying this property is only 21 bytes […]

  • Retaining DPI/PPI Information with PNGGauntlet

    I’ve mentioned PNGGauntlet many times on this blog – it’s a great tool for squeezing the best compression ratios out of the PNG format. It combines the tools PNGOUT, OptiPNG and DeflOpt in a nice WinForms GUI. As part of the compression process, most chunks are removed by default. This includes the pHYs chunk, which […]

  • Image Background Remover Tool

    View source on GitHub. Inspired by Window Clippings, my preferred screenshot tool (which unfortunately crashes a lot under Windows 8 RTM), I wrote a small program for making image backgrounds transparent. It comes with a command-line interface and a basic GUI (pictured above). The GUI supports dragging-and-dropping images, and you can switch the black and […]
