Using a separate Membership Provider to Reset Password

I'm attempting to use a separate membership provider to reset a password for when a user cannot remember their "secret answer". I've added another provider in my web.config file called AspNetSqlMembershipProviderOther.
Now I saw this as an example at http://peterkellner.net/2007/02/15/resetpasswordaspnet/ which was in C#. I'm rewrote it in VB.NET but cannot get it to work.
Dim username As String = "UserName" Dim password As String = "password" Dim mu As MembershipUser = Membership.Providers("AspNetSqlMembershipProviderOther").GetUser(username) mu.ChangePassword(mu.ResetPassword(), password)
