AccessDBProviderSample03

This sample shows how to overwrite the System.Management.Automation.Provider.ItemCmdletProvider.GetItem* and System.Management.Automation.Provider.ItemCmdletProvider.SetItem* methods to support calls to the Get-Item and Set-Item cmdlets. The provider class in this sample derives from the System.Management.Automation.Provider.ItemCmdletProvider class.

Demonstrates

Important

Your provider class will most likely derive from one of the following classes and possibly implement other provider interfaces:

• System.Management.Automation.Provider.ItemCmdletProvider class.
• System.Management.Automation.Provider.ContainerCmdletProvider class. See AccessDBProviderSample04.
• System.Management.Automation.Provider.NavigationCmdletProvider class. See AccessDBProviderSample05.

For more information about choosing which provider class to derive from based on provider features, see Designing Your Windows PowerShell Provider.

This sample demonstrates the following:

• Declaring the CmdletProvider attribute.
• Defining a provider class that derives from the System.Management.Automation.Provider.ItemCmdletProvider class.
• Overwriting the System.Management.Automation.Provider.DriveCmdletProvider.NewDrive* method to change the behavior of the New-PSDrive cmdlet, allowing the user to create new drives. (This sample does not show how to add dynamic parameters to the New-PSDrive cmdlet.)
• Overwriting the System.Management.Automation.Provider.DriveCmdletProvider.RemoveDrive* method to support removing existing drives.
• Overwriting the System.Management.Automation.Provider.ItemCmdletProvider.GetItem* method to change the behavior of the Get-Item cmdlet, allowing the user to retrieve items from the data store. (This sample does not show how to add dynamic parameters to the Get-Item cmdlet.)
• Overwriting the System.Management.Automation.Provider.ItemCmdletProvider.SetItem* method to change the behavior of the Set-Item cmdlet, allowing the user to update the items in the data store. (This sample does not show how to add dynamic parameters to the Get-Item cmdlet.)
• Overwriting the System.Management.Automation.Provider.ItemCmdletProvider.ItemExists* method to change the behavior of the Test-Path cmdlet. (This sample does not show how to add dynamic parameters to the Test-Path cmdlet.)
• Overwriting the System.Management.Automation.Provider.ItemCmdletProvider.IsValidPath* method to determine if the provided path is valid.

Example

This sample shows how to overwrite the methods needed to get and set items in a Microsoft Access data base.
