Public Class Example

' Create a security object that grants no access.
Dim mSec As New RegistrySecurity()
' Add a rule that grants the current user ReadKey
' rights. ReadKey is a combination of four other
' rights. The rule is inherited by all
' contained subkeys.
Dim rule As New RegistryAccessRule(user, _

InheritanceFlags.ContainerInherit, _
PropagationFlags.None, _
AccessControlType.Allow)

' Create a rule that allows the current user only the
' right to query the key/value pairs of a key, using
' the same inheritance and propagation flags as the
' first rule. QueryValues is a constituent of
' ReadKey, so when this rule is removed, using the
' RemoveAccessRule method, ReadKey is broken into
' its constituent parts.

ShowSecurity(mSec)
' Add the second rule back. It merges with the

' Display the rules in the security object.
