Visually display Active Directory Nested Group Membership using PowerShell

In the Active Directory PowerShell module, you have two commands to your disposal that help display group membership. Those are Get-ADGroup and Get-ADGroupMember. The first command contains property Members, which gives you DistinguishedName of all members, and Get-ADGroupMember can provide you either direct members or with Recursive switch all members recursively (skipping groups). Till a few weeks ago, I was a happy user of those commands until I noticed two things. Member property for Get-ADGroup sometimes misses elements for whatever reason.

Nested Tabs, Diagram Updates, Diagram Events, Calendar Object and more in PSWriteHTML

One of the new features I've worked on was connecting Diagrams with Tables. Someone suggested, and I thought it would be cool to be able to click on the Diagram node and find more details about it in a table next to it. But then I thought it would be even cooler if you could have multiple tables linked to one Diagram. For example, below, I've created two tables with Users and Computers and populated Diagram with that data.

Easy way to create diagrams using PowerShell and PSWriteHTML

A few months ago, when I was working on PSWriteWord and PSWriteHTML, I thought to myself that in 2020 if I'll get time, I'll try to create PSWriteVisio. While I wasn't sure I would be able to make it past some concept, it was in my plans for 2020. It's still 2019 though, and while working on Testimo for Active Directory Healthchecks, I thought it would be nice to have a visual representation of network, forest schema or replication. I couldn't get this idea out of my head. I thought on using PSGraph from Kevin Marquette to generate image and import that to PSWriteHTML but it was a bit tricky and PSGraph requires external software to work - and has some additional steps for Windows, Mac or Linux.

Comparing two or more objects visually in PowerShell (cross-platform)

For the last few weeks I'm working on a small project, that should be released within next few weeks (it is open source so don't worry - you'll get to play with it). This project requires me to compare two or more objects and tell if those are equal and if those aren't to what degree. Of course, PowerShell offers built-in functionality via Compare-Object command. It's mighty but it leaves comparing differences, different properties to you. While there are probably other solutions that help users compare objects, I haven't found anything that would meet my requirements. After I've written Compare-MultipleObjects function, I thought it could be interesting to implement visual comparison - you know human-readable - and I had the perfect place to apply it.

Formatting and minifying resources (HTML, CSS, JavaScript) with PowerShell

When you work with HTML, CSS, and JavaScript, you often meet three versions on how those are stored in files - minified, formatted, somewhere in the middle (usually a total mess). I have all three versions in my PSWriteHTML module. Some are minified 3rd party resources, some are generated by my PowerShell commands (and are a total mess when it comes to formatting), and finally, some are formatted resources by using built-in VSCode features. In whatever form they are, they generally have no impact on how browsers display them. Browsers will read them in any kind and not care for how they look.

Working with HTML in PowerShell just got better

Last few weeks, I've been working on making creating HTML based Dashboards, Reports, and Emails better. PSWriteHTML already allows fancy looking reports or emails without much effort, but this release makes it even more helpful. I will be mixing three PowerShell modules in this blost post - PSWriteHTML (responsible for creating HTML/CSS/JS code), Emailimo (simplifies creating emails based on PSWriteHTML) and Dashimo (simple dashboard building). If you've never heard of those modules before I encourage you to start from earlier blogs about them to understand the concepts before you dive into this one.  Hopefully, those will give you some ideas that will match what you will learn today.

Sending HTML emails with PowerShell and zero HTML knowledge required

I saw this article by Altaro tweeted Building PowerShell Tools for MSPs: HTML Tables for Reporting, and it describes how you can create HTML emails with just a few lines of code. Luke created that article in 2018 (tweets from the archive I guess), but I just saw it now so thought I would make a slight comparison. In 2018 I would probably go the same way as shown by Luke Orellana, who takes a simple example of querying WMI to get disk drive sizes and send them over, formatted via Email.

All your HTML Tables are belong to us

Last few days, I've fulfilled my little dream related to building HTML tables. You know I've been using HTML based scripts for a long while for Microsoft Exchange from multiple people like Steve Goodman or Paul Cunningham (and others) and when I was going thru their PowerShell building code on how they create an HTML table with multi-row titles I thought Those guys are crazy. The effort to build an HTML table for a report for a person who has no clue how to do it is not something one can easily digest and understand. Sure I've learned how to build HTML tables at some point, but there was one final piece that I was missing - multi-row headers. If you don't know what I mean, and how they look like the below image from Steve's Goodman script should give you a hint.
