问题 Register-ObjectEvent looks for a object instance in the required parameter InputObject . What is the syntax for an object's static ( Shared ) event? UPDATE : Correct syntax for TimeChanged: $systemEvents = [Microsoft.Win32.SystemEvents] $timeChanged = Register-ObjectEvent -InputObject $systemEvents -EventName 'TimeChanged' -Action { Write-Host "Time changed" } Unfortunately, the SystemEvents will not be signaled in PowerShell ISE . Here's a sample using an object's staic event that works

问题 The PowerShell range operator generates a list of values: >1..6 1 2 3 4 5 6 How can I generate a list of values with a specific step? For example, I need a list from 1 to 10 with step 2. 回答1: The range operator itself doesn't support skipping/stepping, but you could use Where-Object (or the Where() method if you're running version 4.0 or above) to filter out every second: PS C:\> (1..10).Where({$_ % 2 -eq 0}) 2 4 6 8 10 Version 2.0 and up: PS C:\> 1..10 |Where-Object {$_ % 2 -eq 0} 2 4 6 8 10

问题 Setting the below $usbDriveLetter variable to automatically find the USB drive letter, and using that variable to open an image on the USB doesn't work. It literally prints "G:\image.png" in the cmd. $usbDriveLetter = (gwmi win32_volume -f 'label=''USB_NAME_HERE''').Name; "$usbDriveLetter" + "image.png" But if I don't use a var and make "G:\" static in the PowerShell script, the image opens just fine. G:\image.png So what am I doing wrong here? How do we dynamically open images using ps1
