$timer = [Windows.Forms.Timer]::new()
$timer.Interval = 1000
$b=5
function tick {
write-host ($b++)
}
$timer.add_tick({ tick })
$Form = [Windows.Forms.Form]::new()
$Timer.Start()
$Form.Showdialog()
Output always 5. How to make timer be able to see vars from global scope?
You could use the script scope modifier
$timer = [Windows.Forms.Timer]::new()
$timer.Interval = 1000
$script:b=5
function tick {
write-host ($script:b++)
}
$timer.add_tick({ tick })
$Form = [Windows.Forms.Form]::new()
$Timer.Start()
$Form.Showdialog()
