Protecting to class - this doesnt work (& the tried
role:="administrators", name:="administrator" etc)
< PrincipalPermissionAttribute(SecurityAction.Demand, Role:="BUILTIN
\Administrators") _
Public Class Form1 Inherits System.Windows.Forms.Form
Private Sub Form1_Load(ByVal sender As System.Object, ByVal and As
System.EventArgs) Handles MyBase.Load
Messagebox("form should load if user is admin")
End Sub

PrincipalPermissionAttribute class is used to control access to
methods, not classes, so move the attribute statement to just before
the method you want to control. You also need a
system.appdomain.currentdomain.setprincipalpolicy statement in the
constructor for the form. Then, put the call to the method in a try/
catch block to trap any exception that the runtime might throwif
there are not adequate permissions to execute the method.

thanks but msdn says you can protect a class (but i havent got the
example to work for me) and gives this example
<PrincipalPermissionAttribute(SecurityAction.Demand, _
Name := "Bob", Role := "Supervisor")> Public Class SampleClass



my question is when protecting a class, where do you put the call to
system.appdomain.currentdomain.setprincipalpolicy ?

is there an attribute that does this for assemblyinfo.vb?

thx
