Updated PowerShell TreeForm
Not too long ago I wrote a blog post about a Windows Form PowerShell script to display a folder tree. I got some feedback about an error when running the script. The problem was that I was casting a variable in one of the functions to a specific type. Normally this is considered a best practice. But in this situation the [System.Windows.Forms.TreeNode] class depends on the parent class being loaded in your PowerShell session. Even though I thought I had tested thoroughly on PowerShell v1 and v2 I must have missed something and the [System.WIndows.Forms] class was getting loaded into my shell prior to running the script, which is why I never saw the error. Anyway, I’ve since modified the problematic function to remove the type casting.
More Fun with Debug Messages
A few weeks ago I posted an entry on creating customized debug messages that you can use in your scripting. After some more testing and tweaking I revised and renamed the function. Write-DebugMessage can now be used within your script to send messages to the debug pipeline. I moved the $debugpreference setting to the function itself and made other improvements.
