In previous versions of VB, we needed to use complicated API functions to get special folder locations such as "my documents" and "my computer", while VB.NET provided us with the Environment.GetFolderPath method, which allows us to use one line of code to achieve effects that previously required complex code to complete.

The VB.NET Environment class is the information that .NET provides about the current environment and platform and the methods to manipulate them. You can use the VB.NET Environment class to retrieve information, such as command-line parameters, exit code, environment variable settings, the contents of the call stack, the time since the last system boot, and the version of the common language runtime.

A GetFolderPath method is provided in the VB.NET Environment class that allows us to get the path to the system-specific folder identified by the specified enumeration. Returns the path to a special folder for the specified system if it actually exists on the computer; otherwise, an empty string (").

Here are a few commonly used special folder acquisition code: 'get the logical desktop, note that it is not the physical file system location.

Environment.GetFolderPath (Environment.SpecialFolder.Desktop) 'gets the directory used to physically store file objects on the desktop. Environment.GetFolderPath (Environment.SpecialFolder.DesktopDirectory) 'get the my computer folder. Environment.GetFolderPath (Environment.SpecialFolder.MyComputer 'get the my documents folder. Environment.GetFolderPath (Environment.SpecialFolder.Personal) http://www.qqread.com/book/myvbnet/my0055.html 'gets the location of the IE's History folder. Environment.GetFolderPath (Environment.SpecialFolder.History)

There are other enumerated values for special folders that are not commonly used, which we will not explain.
