    '  If the request was not canceled and did not throw
    '  an exception, display the resource.
    If e.Cancelled = False AndAlso e.Error Is Nothing Then

If the Error property's value is an Exception object or the Cancelled property's value is true, the asynchronous operation did not complete correctly and the Result property's value will not be valid.
