Yesterday, we created a simple Powershell menu

http://www.get-virtual.info/2011/01/26/script-of-the-day-powershell-menu-select-list/

Today’s script is a feeder for the menu, that allows you use any filed of an object as your menu source and return a different field of it as your return value.

For Example:
the following query will give you a list of the filenames in the current directory, once you select an item, it will return that ‘LastWriteTime’ of that file. – Simple

PS:8 >menu-plus -object (gci) -displayfield "name" -menuTitle Please select a file -returnfield "LastWriteTime"

Function menu-plus ($object, $displayfield, $menuTitle, $returnfield)

{
<#
