Creating a QR Code Reader App for Windows Phone 7

If you’ve updated Windows Phone 7.5, you might have noticed that it has some nice built-in functionality for reading QR Codes using Bing Vision search.  After trying it out for a while, I pretty quickly started wondering how I could use this in an app, and equally quickly I was disappointed to find that there…

Here’s a quick diversion to exercise your basic scripting skills: FizzBuzz is a game often played by schoolchildren as a way to practice their metal arithmetic abilities (or as a game for drunken adults, if you listen to Wikipedia).  The rules we will use are: Count from 1 to 100, displaying the numbers as you…

WMI Date Formats … PowerShell to the Rescue

If you use WMI in your PowerShell scripts you’ll probably have noticed that dates are shown in a rather odd format.  For example: Get-WmiObject –Class Win32_BIOS |      Format-Table Description, ReleaseDate -AutoSize Description          ReleaseDate              ———–          ———–              Phoenix ROM BIOS A14 20090511000000.000000+000 While you can read the dates (they are in “year-month-day-hour-minute-second” format), they are difficult…

PowerShell Diversion #4: Can You Count on PowerShell?

Here’s a problem that is more abstract and a bit trickier than the previous ‘diversions’.  It doesn’t require anything very sophisticated or obscure in terms of PowerShell, but might take a bit of extra thought on how to construct your solution.

PowerShell Diversion #2: Charts, Tables and Events

In an old post I discussed using the Microsoft Chart Controls to generate some professional looking charts from PowerShell.  These are great if you want to use the charts in a formal report or presentation, but what if all you want is a basic bar chart to help you quickly compare some values in a…
