   End Interface


   Imports System.Runtime.Remoting
   Imports ClassInterfaces

   Public Class ZoneLogIn
       Inherits MarshalByRefObject
       Implements ClassInterfaces.MyInterface

        Private mLogInSuccesfull As Boolean

        Public ReadOnly Property LogInSuccessfull() As Boolean Implements ClassInterfaces.MyInterface.LogInSuccessfull
          Get
             return mLogInSuccesfull
          End Get
       End Property

       Public Sub TryToLogIn(ByVal UserName As String, ByVal UserPassword As String) Implements  ClassInterfaces.MyInterface.TryToLogIn
         mLogInSuccesfull =true
         Console.WriteLine(mErrorMsg)
       End Sub

   End Class


   Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
       Dim test As ClassInterfaces.MyInterface
       test = CType(Activator.GetObject(GetType(ClassInterfaces.MyInterface), "tcp://172.10.1.2:49341/ZoneLogIn.rem"), ClassInterfaces.MyInterface)
       test.TryToLogIn("test", "1234")

推荐答案

您确定对象创建正确吗?从网址获取test IsNot Nothing后可以检查吗?

Are you sure the object is created properly? Can you check if test IsNot Nothing after getting it from the URL?
