Why not create your own PowerShell attributes? It only takes a couple of lines, and the results can be astonishing!
There is a lot of confusion about Corona/COVID-19 and events taking place in the next months. Here you find the latest status for psconf.eu 2020.
The Abstract Syntax Tree (AST) groups tokens into meaningful structures and is the most sophisticated way of analyzing PowerShell code.
Enable argument completion for your own function parameters and make them so much easier to use! Some lesser-known attributes can help you.
Transformation attributes are a sophisticated way to convert one data type into another. Whenever built-in type conversion fails, transformation attributes can perform the required transformation.
Validation attributes monitor and make sure values assigned to variables and parameters meet your requirements. And they can do plenty more!
With the help of the attribute [Parameter()], you can define sophisticated PowerShell parameters that enhance usability and versatility of your functions.
Make sure your functions are indeed "Advanced Functions", and add Risk Mitigation support to make your code safer to use.

Attributes can add powerful functionality to your PowerShell code and shorten your code considerably. Let's discover un(der)documented PowerShell attributes and use them to control PowerShell.
June 2, 2020, psconf.eu opens for the 5th time in Hannover, Germany. Here is a quick walkthrough for this years’ event.
All trainings are delivered by PowerShell expert and long-term MVP Dr. Tobias Weltner.
While our inhouse trainings are always individual, we have a number of sample packages that you can start with. We’ll gladly compose a perfect individual training for you - with you. PowerShell Essentials (2-Day) This is our popular PowerShell boot camp for all IT staff, even those that only occasionally run a PowerShell one-liner. The goal is...
Alle Trainings werden von PowerShell-Experte Dr. Tobias Weltner durchgeführt.
Unsere Inhouse Workshops sind stets individuell geplant, aber wir haben typische Beispiel-Workshops, mit denen Ihre Planung starten kann.
A big “Thank You!” to all the speakers who are volunteering to deliver sessions at psconf.eu 2020!
Wouldn’t it be nice for scripts to detect when a key is pressed? Pressing a key could add a pause to scripts, exit loops prematurely, or skip loading things in your profile script.
Ever wanted to find files with identical content? With file hashing and a bit of cleverness, PowerShell identifies duplicate files in no time.
Learn how to use other languages to teach PowerShell new tricks, for example how to reliably bring application windows to the front.
PowerShell 7 is the new cross-platform version of PowerShell and can be installed on a wide range of operating systems, including Windows, Linux, MacOS.
There is a design flaw in Group-Object. With a workaround, your scripts can be up to 50x faster and still 2x faster on PowerShell Core.
Many scripts load external DLL files to get access to more functionality. Those files can be embedded into scripts as text to remove dependencies.
Appending text to strings using “+=” is convenient but slow. Learn how to do string manipulation without slowing down PowerShell.
The advanced PowerShell Parser turns PowerShell code into detailed tokens. Use them to auto-document, analyze or just find your scripts. You can also perfectly colorize your code.
Traditional looping constructs like “foreach” and “do...while” cannot stream: you need to wait for all results to be done. With a simple trick, you can add streaming.
In code reviews, one common mistake stands out: using += on arrays. Learn how to 3.5x speed up your PowerShell scripts by avoiding +=.
By turning PowerShell code into tokens and structures, you can find errors, auto-document your code, and create powerful refactoring tools.
With a FileSystemWatcher, you can monitor folders for file changes and respond immediately when changes are detected. This way, you can create “drop” folders and respond to log file changes.
The PowerShell Pipeline is robust but tends to be slow. With a couple of tricks you can speed it up tremendously and make it as fast as classic foreach loops.

PowerShell Conference EU is Europe’s largest annual PowerShell conference. Delegate registration for psconf.eu 2020 is open now.
The module QRCodeGenerator generates a variety of QR codes. All QR codes are generated offline and not shared with any service. The module works cross-platform (Windows PowerShell, PowerShell Core).
PowerShell ships with Test-Connection to ping computers but this command lacks important parameters such as a timeout. Let’s create a better ping command with a timeout parameter.
Just a few lines of code suffice to add a powerful and flexible port testing command to PowerShell. Test-PSOnePort can test a single port with a timeout - once, or continously until it responds.
Last week, our servers running http://powertheshell.com in the US died on us. That was a rather unpleasant surprise: our servers hosted the ISESteroids documentation and a lot of resources that built up during the past 10 years.
