Hide SharePoint Calculated Columns

Note that you can't hide the SharePoint calculated columns by the normal way, you have to use PowerShell to do that !

$web = get-spweb http://SPWeb/Site/subsite
$list = $web.Lists["list name"]

$field = $list.Fields["Column Name"]
$field.ShowInDisplayForm = $false
$field.ShowInEditForm = $false
$field.ShowInListSettings = $false$field.ShowInVersionHistory = $false$field.ShowInViewForms = $false
$field.ShowInNewForm = $false

$field.Update($true)
$web.Site.Dispose()
