We have seen issues reported in our support forum where Azure commands are not terminating, or more likely their cmdlets are not returning in a GUI environment. This is due to the Powershell pipeline being held up by the GUI, which could prevent Powershell from processing internal messages and events thus causing a hang when a […]

PowerShell GUI Apps: Why think in events?
Always committed to starting the New Year right, I’m heading to Scottsdale, Arizona on Tuesday, January 5 at 5:30 PM to meet with the newly revived Arizona PowerShell User Group. We’ll meet at the Microsoft Store in Scottsdale Fashion Square. (I will not be distracted by the Surface Pro 4 on display. I will not…) […]
Spotlight on the Label Control
The Spotlight on Controls series describes the controls, that is, the objects in the System.Windows.Forms namespace, so you can use them effectively when building GUI apps in PowerShell Studio and PrimalScript. Each post focuses on one control and lists its most important properties, methods, and events, including the default event that PowerShell Studio adds to […]
Scope in a PowerShell GUI App
If you search the SAPIEN blog, you’ll realize that this is the not our first blog about scope in PowerShell GUIs.

That makes me a great amateur tester and, due to a lifetime of experience with breaking things, a pretty good debugger. But, at the Omaha PowerShell User Group meeting in August […]
The Methods that Register Events
If you create PowerShell GUI apps in PowerShell Studio, you become very familiar with the events of the Windows Forms types, like the Load event of forms, the Click event of buttons, and the TextChanged event of textboxes. PowerShell Studio handles most of the background details of event management for you, but it’s useful and […]
PowerShell GUIs: Where do I start?
Follow @juneb_get_help I’ve been using Windows PowerShell since the very first version of Monad in 2005, but PowerShell-based applications with a graphic user interface (GUI) are a whole new world. Instead of thinking of cmdlets and parameters or properties and methods, you need to think in object events. And because there’s no console with .ps1xml-directed […]
Displaying Output in a GUI Application
After many years of writing scripts for the Windows PowerShell console, I’m now learning the next level of automation — writing GUI applications that run Windows PowerShell commands. PowerShell Studio forms provide a gentle and well-guided introduction to GUI applications, but it’s still taken me some time to break old habits. I constantly need to […]
