title: How to call function in a Powershell Write-Host statement
body: <pre><code>$BizTalkHelper = "d:\Scripts\BizTalkHelper.ps1"
  .$BizTalkHelper # "dot source" the helper library.
  Write-Host *** BEGIN ***
  
  Write-Host $(Get-Date) " Desc:" {GetHostStateDesc 1 }
  Write-Host $(Get-Date) " Desc:" GetHostStateDesc 2 
  
  $result = GetHostStateDesc 1 
  Write-Host $result 
  </code></pre>
  
  <p>My functions prints "hello", in addition to a switch statement to translate 1 to 'Stopped', 2 to 'Start Pending', 4 to 'Running', etc... 
  So I know it's not getting called in the first two cases. </p>
  
  <p>Results: </p>
  
  <pre><code>*** BEGIN *** 
  3/29/2013 11:03:34 AM  Desc: GetHostStateDesc 1 
  3/29/2013 11:03:34 AM  Desc: GetHostStateDesc 2 
  hello 
  Function GetHostStateDesc  1 
  Stopped
  </code></pre>
