PowerShell snippet: check if software is not installed

Some deployment scripts need to check if certain required software is installed on a Windows Machine. You could check if the file is present at a certain location, but there is a better way to check if software is installed: the uninstall database in the Windows Registry. PowerShell makes it really easy to query the registry!

Having a diagram of how your Visual Studio projects interlink, can be a big help. I’ve created a small PowerShell script that will produce the diagram based on the .csproj files in a directory. It will generate Yuml.me diagrams!

Create mp3 playlist with PowerShell

Playlist are a dandy way of organizing the files into one list (easy to find on your device). The m3u playlist format is a no-hassle straight forward format, that’s why I love it. It is basically a list of relative file paths. Well… if it is that simple, it should be easy to write into a PowerShell statement.

$1 Regex Replacement Problem PowerShell [solved]

Madre mia! I’ve been trying to edit an HTML file using PowerShell. I only wanted to eliminate all the spans and paragraphs using regular expressions (would make sense)… and how hard can that be?
Well, it turned out to be pretty hard if you’re used to the replacement syntax of regular .Net expressions! After searching for hours I’ve discovered that $1 can’t be used in the same way as in .Net. Just use ${1}. Ouch!
