# find the path to the desktop folder: $desktop = :: GetFolderPath ( 'Desktop' ) # specify the path to the folder you want to monitor: $Path = $desktop # specify which files you want to monitor $FileFilter = '*' # specify whether you want to monitor subfolders as well: $IncludeSubfolders = $true # specify the file or folder properties you want to monitor: $AttributeFilter = :: FileName, :: LastWrite # specify the type of changes you want to monitor: $ChangeTypes = :: Created, :: Deleted # specify the maximum time (in milliseconds) you want to wait for changes: $Timeout = 1000 # define a function that gets called for every change: function Invoke-SomeAction # subscribe your event handler to all event types that are # important to you. Whenever a change is detected, Invoke-SomeAction is called. This is straight-forward: the script below monitors your desktop and all of its subfolders for new files and for deletion of files. However, responding to events is not trivial in a single-threaded environment like PowerShell. This way, you cannot miss change events because the FileSystemWatcher is constantly monitoring. Instead, whenever a change occurs, an event is fired, and your script can respond to the events. Advanced Mode: In asynchronous mode, the FileSystemWatcher does not block PowerShell.This approachis very simple to implement however there is a chance to miss change events when they occur in rapid succession.


This blocks PowerShell until either the change occurs or a timeout is reached.

The source location will have one or more text files. Could someone assist me with the creation of a windows service in VB.net 2008 to copy a text file from one location to another location?
