Specified cast is not valid

| Hi all,
I'm using VB.net in my project and I'm getting this error when assigning the
HttpContext user identity to windows identity. FYI, i must use
AuthenticateUsingUserHandle method.
Dim cmsAppContext As New CmsApplicationContext
Dim winIdent As System.Security.Principal.WindowsIdentity =
HttpContext.Current.User.Identity
cmsAppContext.AuthenticateUsingUserHandle(winIdent.Token,
PublishingMode.Unpublished)
How can I go about it?
Sample in C# is here
http://support.microsoft.com/?kbid=327750
Thanks

| Lam before you assign it make sure it is not null make a check like
this
HttpContext.Current.User.Identity.IsAuthenticated ....For Guest users
it will be null ...

| Hi Lam,
I checked your code and it works without any problem for me. Can you post
the exact error message that you get when you build the project?
Cheers,
Chester.
