If you search the SAPIEN blog, you’ll realize that this is the not our first blog about scope in PowerShell GUIs. In March 2013, SAPIEN CTO Alex Riedel wrote First Rule of PowerShell Scoping Rules, a title that implies the final word in a discussion that wasn’t easy to end. Alex’s blog explained the differences […]

PowerShell GUI Debugging Tip: Duplicate Event Handlers
I’m not a professional tester, but I am an expert at making mistakes. I take risks. I try everything. I gravitate to “corner cases” and odd circumstances. 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 […]
Typing Enter Pushes a Button
As a beginner developer of PowerShell GUIs, I’m always looking for easy ways to make my simple applications more sophisticated and usable. One of the basic usability features in most applications is typing <Enter> in a textbox to invoke a function instead of clicking a Start, Go, or OK button. In this post, I’ll show […]
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 […]
Copy to Clipboard in a GUI Application
Follow @juneb_get_help During #PSBlogWeek, I shared with my co-authors a little GUI-based blogging tool that gets links to the online version of PowerShell help topics, including About topics. I didn’t think much of it, because it was my first GUI app, but I soon received a nice compliment from PowerShell MVP Jeffery Hicks with a […]
Adding auto-complete to an input textbox
Follow @juneb_get_help Well-designed user interfaces make it as easy as possible for the user to enter the right input in the right format. One of the most effective ways to help a user is to provide suggested input or automatically complete the input that the user begins to type. As a UI newbie, I thought […]
Creating a GUI for CSV Data
Follow @juneb_get_help I often manage data in CSV files, typically data that originates in an Excel spreadsheet. The Import-Csv cmdlet, which creates custom objects from the contents of a CSV file, makes CSV data an optimal choice in Windows PowerShell. But, how do you manage CSV data in a Windows UI? PowerShell Studio offers several […]
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 […]
Spotlight on the ToolTip 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 […]
