Powershell carriage return not working - powershell

Question

$startTime = $(get-date)
write-host "`rElapsed:00:00:00"
$NoEvent = $true
While ($NoEvent)
{
Start-Sleep 1
$elapsedTime = new-timespan $startTime $(get-date)
write-host "`rElapsed:$($elapsedTime.ToString('hh\:mm\:ss'))"
#Handle event
if(event){$NoEvent = $false}
}
I've tried running this in the ISE as well as through the regular console. The returns are never output.

Answer 1

I eventually got it working using -NoNewLine switch
write-host -NoNewLine "`rElapsed:$($elapsedTime.ToString('hh\:mm\:ss'))"

Answer 2

`r only issues a CR, not a CR+LF (which is probably what you want). Use `n (‘newline’) instead.

Answer 3

I don't think there is any PS cmdlet that can help with overwriting text from the same line unless you are clearing the entire window with clear-host or cls, but PowerShell has a built in write-progress cmdlet if that is something else you would want to consider.
You can try:
$startTime = $(get-date)
$NoEvent = $true
While ($NoEvent)
{
for ($a=1; $a -lt 100; $a++) {
Start-Sleep 1
$elapsedTime = new-timespan $startTime $(get-date)
Write-Progress -Activity "`rElapsed:$($elapsedTime.ToString('hh\:mm\:ss'))" -PercentComplete $a -CurrentOperation "$a% Processed" -Status "Please wait."
#Handle event
if(event){$NoEvent = $false}
}
}
