powershell script: progress bar infinite loop, until key pressed

Question

Hi all,
I would have to create a script (powershell or DOS) doing this:

a wording printed (e.g. "debug in progress:") and beside a progress bar (dots increasing....)
when the dots reach number of 100, they start from 1 dot (still beside the same wording):

debug in progress:...........................

this in an infinite loop, until I press a key

is it possible?
thanks!

Hi,

You can try something like this.

$notpressed = $true  
$string = 'debug in progress:'  
$dots = 100  
$i = 0  
while($notpressed){  
    $i++  
    if([console]::KeyAvailable)  
    {  
        $notpressed = $false      
    }      
    else{  
        if($i%($dots+1) -eq 1)  
        {  
            Write-Host $string -NoNewline  
            Start-Sleep -Milliseconds 500            
        }  
        elseif($i%($dots+1) -eq 0)  
        {  
            Write-Host '.'  
            Start-Sleep -Milliseconds 500             
        }  
        else{  
            Write-Host '.' -NoNewline  
            Start-Sleep -Milliseconds 500             
        }  
    }  
}
