1) code there variable ' $htmlheader = @" ' what means ?
the @" "@ convenient way of defining long string constant on many lines.
2) variable ' $servicesreport = @() ' means ?
@() defining new empty array.
the += operator in " $servicereport += $row " adding new element array.
3)and below statement ?
$row = new-object -type psobject -property @{ .... }
creating powershell object, properties , values defined in hashtable
@{} defines hashtable,
powershell objects different traditional objects in properties of object defined / constructed @ run-time vs other objects / classes defined @ compile time.
