My main home computer is running Windows 10 and Hyper-V, and I was really looking forward to the anniversary update. PowerShell Direct, nested virtualization, and containers all sound awesome. I’ve played with them in a test box, but not on my main box. So…I got home after work the day of the update, installed it …

This is not a world-changing topic, but I thought it was worth sharing. If you have written hashtable literals on a single line, you’ve seen this before: Sometimes, it makes more sense to write the hashtable over several lines, especially if it has several items. I’ve always written them like this: I was watching Don …

A couple of weeks ago, Adam Bertram wrote a post which got me really excited. As an aside, if you’re not following Adam you’re missing out. He posts ridiculously often and writes high quality posts about all kinds of cool stuff. I’m writing about one such post. Anyway, his post was about using the PSTypeName …
In working on VisioBot3000, I’ve spent a lot of time looking at VBA in Visio’s macro editor. It’s one of the easiest ways to find out how things work. I thought it would be fun to take some VBA and convert it to PowerShell to demonstrate the process. We’ll start with a basic diagram using …
You probably learned early on in your PowerShell experience that -eq and = were very different things. I still occasionally write when I mean to write The first will always evaluate to $true, which is generally not what you want. One trick I’ve seen before is to put the constant (if there is one) on …

In the last post I showed you how VisioBot3000 makes drawing simple Visio diagrams simpler by wrapping the Visio COM API and providing more straight-forward cmdlets do refer to stencils and masters, and to draw shapes, containers, and connectors on the page. To be honest, that’s where I was expecting to end up when I started …

For a while now, I’ve been demonstrating Visio automation in PowerShell. For the most part, the posts have included a bunch of short code snippets designed to illustrate simple concepts. Unfortunately, the code has been filled with “magic” constants, and lots of method calls on the various Visio COM objects. Both of those make code …

Ok…I think this is the last of the “how to perform primitive operations in Visio” articles that I’m going to do. Hope you’ve been enjoying them. If you haven’t been keeping up, you can find them all here. In this installment, I’m going to show you how to create a container in Visio. Containers are really …

Last night Rob Campbell (@mjolinor) and I were talking after his presentation on performance when using Get-Content with -ReadCount and different string matching techniques and I realized it’s time to verbalize my thoughts on performance in PowerShell. Part 1 – It doesn’t matter When people ask me if PowerShell is fast, my first response is …
It’s been a while since the last post. I decided that if I had to chose between writing PowerShell and writing about PowerShell, I should favor the former. In this episode, I’ll talk about how to create connections between objects in a Visio diagram. Turns out it’s not really that hard (just like most things …
