Powershell script to stop the windows service not working . No error is thrown either

Question

This script has a function that accepts a parameter (service to be stopped). I ran the script the following way. But the service wouldn't stop. Also for some reason nothing is being written to the console. Where is the Write-Host is writing to? I am using Powershell Version 4.0 on windows 8 OS.

  .\MywindowsService.ps1 Dhcp -force 

  function StopWindowsService
  {
         Param([string] $ServiceName)
         $aService = Get-Service -Name $ServiceName
        if ($aService.Status -ne "Stopped")
        {
               Stop-Service $ServiceName
               Write-Host "Stopping " $ServiceName " service" 
               " ---------------------- " 
              " Service is now stopped"
         }

        if ($aService.Status -eq "stopped"){ 
             Write-Host "$ServiceName service is already stopped"
        }

   }

You could try this - mywindowsservice.ps1:

Param([string] $ServiceName)

$aService = Get-Service -Name $ServiceName

if ($aService.Status -ne "Stopped") {
    Stop-Service $ServiceName
    Write-Host "Stopping " $ServiceName " service"
    " ---------------------- "
    " Service is now stopped"
}

if ($aService.Status -eq "stopped") {
    Write-Host "$ServiceName service is already stopped"
}

Call:

.\mywindowsservice.ps1 dhcp

Declaring function StopWindowsService means you need to call StopWindowsService inside the ps1 file to actually execute the code. It is not needed here.
