  1. Hi
    I tried to run this script on MOSS 2007 by adding
    [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint") >null

    And changing this line but got the error. Could you help me resolve the error or i need to find some other property to use.

    $List = $WebURL | Select -ExpandProperty "Lists" | Where-Object{$_.Title -eq $ListName}
    Select-Object : Property "Lists" cannot be found.


    1. Use this post to use PowerShell in MOSS 2007: How to use PowerShell with MOSS 2007?
      $Web = Get-SPWeb($url)
      $List = $Web.Lists[$ListName]

    2. Hi Salaudeen
      sorry for being such a novice. here my PS

      [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint") >null
      $url = "http://mosssp/sites/TestbySPAdmin"
      $ListName = "DocumentLibrary"
      Function global:Get-SPWeb($url)
      $site= New-Object Microsoft.SharePoint.SPSite($url)
      if($site -ne $null)
      return $web
      $Web = Get-SPWeb($url)
      $List = $Web.Lists($ListName)

      but i got the error
      Method invocation failed because [Microsoft.SharePoint.SPWeb] doesn't contain a method named 'Lists'.
      At line:16 char:19


    3. The Line: $List = $Web.Lists($ListName) should be "$List = $Web.Lists[$ListName]"

  2. Thanks so much. My mistake. should have see that. It work great now on MOSS 2007. Thanks again.

  3. Hi Salaudeen

    Another question please. how do I use this script for the top site and all sub sites under it to call the Function to retrieve detailed Library storage Report for each site.


    1. Hi Salaudeen

      Thanks so much. That have everything I want to accomplish. But more than anything. Thanks for such clear explanation in each part of the script. Help me to understand and I learn a lot from this.
