Parameter validation affects parameter variables
Follow @juneb_get_help In a Google+ discussion this week, Edi Prinz demonstrated an effect of the ValidationRange parameter attribute that surprised many of us.

For example, this function […]
Creating a GUI for CSV Data
Follow @juneb_get_help I often manage data in CSV files, typically data that originates in an Excel spreadsheet. The Import-Csv cmdlet, which creates custom objects from the contents of a CSV file, makes CSV data an optimal choice in Windows PowerShell. But, how do you manage CSV data in a Windows UI?

Enumerated Types in Windows PowerShell 5.0
Follow @juneb_get_help [Update: The original post referred to “enums” as “enumerators” when, in fact, they are “enumerated types.” By contrast, enumerators allow you to process items one at a time. Many thanks to Windows PowerShell MVP Dave Wyatt (@msh_Dave) for the correction.] Enums have always been a part of Windows PowerShell, because they’re an important part […]
Find variables with class
Follow @juneb_get_help I’ve been playing with the Windows PowerShell 5.0 preview and especially with its new class feature. After I create my class, I often create several instances of the class and experiment with them in my session. For example, I created a Wine class and then created several instances of my wine class. I […]
