Question

I want to write to console from an asynchronus event in powershell.

$timer = New-Object Timers.Timer
$timer.Interval = 2000     
$timer.AutoReset = $false  
$timer.Enabled = $true

Register-ObjectEvent -InputObject $timer -EventName Elapsed -SourceIdentifier c4n4 -Action {Write-Host test}

This obviously works. But if i encapsulate the Write-Host action within a function. It doesnt anymore.

function myFunc{
  Write-Host test
}

$timer = New-Object Timers.Timer
$timer.Interval = 2000     
$timer.AutoReset = $false  
$timer.Enabled = $true

Register-ObjectEvent -InputObject $timer -EventName Elapsed -SourceIdentifier c4n4  -Action {myFunc}

So basically my question is. How do i write to console from an event within a function?

Answer 1

You need to declare the function in the global scope:

function global:myFunc{
  Write-Host test
}
