POWERSHELL WAIT FOR INPUT CODE
(I prefer to do all of this in XAML markup and code I assume PowerShell Studio facilitates doing this in GUI, and generates the resulting code.) ShowDialog() method of the form or window. You define your Form (or Window), add Controls to it - either directly or via Panel wrappers that are themselves Controls - hook Events up to these Controls, and then display your interface using the. I've generated a PowerShell GUI interface for that exact purpose before, although I used the newer Windows Presentation Framework in place of the legacy System Windows Forms.įor the purposes of your question, however, the distinction between the two is irrelevant they both use the same Event-driven model, and even the same methods for kicking it off and ending it.

The Read-Host cmdlet has an AsSecureString parameter which allows the user to not only store the output as a secure string but also to show asterisk while typing to hide your secret from prying eyes! To get around this, PowerShell has a concept called a secure string which is a simple string that’s encrypted.Ī secure string can any kind of sensitive information a password is a great example. Likewise, it’s never a good idea to have passwords stored in plain text in memory either. You should know it’s not a good idea to store passwords in plain text in your scripts. Warning when no input Asking for Passwords You can see below that by executing Read-Host within the PowerShell console itself using the Prompt parameter, PowerShell is stopping all execution and displays my prompt message giving the user an explanatory message as to what we’re after. For example, if your script requires a server name, you might choose to use Read-Host to prompt the user to input that when the script is run. This Prompt parameter allows you to give the script user some kind of indication as to what to input. Read-Host is a simple cmdlet but one that comes in useful when needing to get information from the script user.Īt it’s most basic, the Read-Host cmdlet simply requires using the Prompt parameter.

Let’s see some real-world applications on how we can use the Read-Host PowerShell cmdlet. Using the Read-Host PowerShell cmdlet, you can interactively prompt for input from the script user.
