Examples

The following code example shows the use of the AddPathList(RegistryPermissionAccess, String) method.

// AddPathList adds access for the specified registry variables to the existing state of the permission.
// SetPathList sets new access for the specified registry variable names to the existing state of the permission.
// GetPathList gets paths for all registry variables with the specified RegistryPermissionAccess.

Public Sub AddPathList (access As RegistryPermissionAccess, actions As AccessControlActions, pathList As String)
Public Sub AddPathList (access As RegistryPermissionAccess, control As AccessControlActions, pathList As String)

Parameters

actionscontrol
AccessControlActions

One of the AccessControlActions values.

pathList
String

A list of registry variables (separated by semicolons).

Exceptions

The access parameter is not a valid value of RegistryPermissionAccess.

-or-

The pathList parameter is not a valid string.

Remarks

Use this method to modify access to registry variables by adding the set of their paths to the state of the current permission object. This overload allows you to specify the access control action as will as the registry permission access.

The control parameter specifies whether the access control list (ACL) for the registry keys specified by pathList can be changed, viewed, or cannot be accessed.

Important

An access control list (ACL) describes individuals or groups who have, or do not have, rights to specific actions on the specified registry keys. The ability to change or view an ACL is an important permission and should be granted with caution.
