Question

How it is possible to call a function from a other PowerShell script an returning the object?

Main Script:

# Run function script
. C:\MySystem\Functions.ps1

RunIE

$ie.Navigate("http://www.stackoverflow.com")  
# The Object $ie is not existing

Functions Script:

function RunIE($ie) 
{
$ie = New-Object -ComObject InternetExplorer.Application
}

Answer 1

Just “output” the object from the function like so:

function RunIE
{ 
    $ie = New-Object -ComObject InternetExplorer.Application 
    Write-Output $ie
} 

or more idiomatically

function RunIE 
{ 
    New-Object -ComObject InternetExplorer.Application 
} 

Then assign the output to a variable in your main script:

$ie = RunIE
