Dim value As String = My.Computer.FileSystem.SpecialDirectories.AllUsersApplicationData
' Declaration
Public ReadOnly Property AllUsersApplicationData As String
Property Value
String.
Exceptions
The following condition may cause an exception:
- The path is empty, usually because the operating system does not support the directory (DirectoryNotFoundException).
Remarks
The My.Computer.FileSystem.SpecialDirectories Object contains paths to commonly referenced directories.
If the path does not exist, it is created with the following format: BasePath\CompanyName\ProductName\Version
A typical BasePath in Windows XP is C:\Documents and Settings\All Users\Application Data. The CompanyName, ProductName, and Version can be obtained from the My.Application.Info.CompanyName, My.Application.Info.ProductName, and My.Application.Info.Version properties.
Note
If the Company and Product names are not specified in the Assembly Information dialog box, the CompanyName\ProductName in the path are replaced with the assembly name. For more information on setting assembly information names, see How to: Specify Assembly Information (Visual Basic, C#).
Example
This example displays the path for shared application data in a MessageBox.
