In this follow-up to my previous post on building GUIs with PowerShell, I walk through a practical example: a GUI-based log viewer. This tool allows users to filter and open log files without needing PowerShell knowledge—perfect for sharing with colleagues. I explain each step of the script, from setting up the form and controls to handling events and filtering logs. The code is available on GitHub and is intentionally left open for customization and learning.

Need to know which parameters were actually passed to your function? $PSBoundParameters has you covered. It’s a built-in dictionary that only includes parameters explicitly provided by the caller. This makes it perfect for clean logic, dynamic behavior, or smart defaults—no need to check for $null or rely on default values. If a key exists in $PSBoundParameters, you know the user meant to pass it.
