   Hi,
   

   
   I too have the same problem. Did you find any solution for that?

   Thanks again but I'm sorry to say I'm still not even in the stage you described in your reply of using a method of the remote object. I'm getting this exception in the following line:
   
   -----------------------------------VB Code------------------------------------------------------------
   Sub Main()
   
          ChannelServices.RegisterChannel(New HttpChannel())
          Dim factory As RemotingClientsInterfaces.IAccountantExamFactory   'this is the object Im tring to remote
   
          'this is the line where the excaption accure
          factory = CType(Activator.GetObject( _
                        Type.GetType("RemotingClientsInterfaces.IAccountantExamFactory"), _
                         "http://10.0.0.172:8080/IExamFactory"), RemotingClientsInterfaces.IAccountantExamFactory)
   
         .
         .
         .
   ---------------------------end of Code-------------------------------------------------------------------
   
   See anything suspicious ???

   You may well find that is due to the use of the "Optional" keyword in VB.NET with a default value, rather than overloading the methods. Default values are not supported in C#. (... there are a few caveats when using different languages). So basically, when calling the VB.NET methods, ensure you provide all parameters including the "Optional" ones.

   thanks for the reply.
   
   Its time for me to be more specific.
   
   I wrote a server client application in C# using remoting
   and it worked. Then I replaced the client with another
   clients written in VB.NET and got an exception while trying to create the remote object:
   
   "An unhandled exception of
   type 'System.ArgumentNullException' occurred in
   mscorlib.dll
   Additional information: Value cannot be null."
   
   do you have any suggestions what so ever ???

   I can certainly say that it is possible - the great thing with .NET is its ability to not care what .NET language you write any components in.... but I haven't got any examples, I'm afraid.

   Can I use remoting when the server is written in C# and the client in VB.NET ? If so does any one knows where I can find an example for this?

   Thanks

   Well the article describes very well how to use .NET Remoting in your application.But does not give a good comparision with widely used remoting procedure i,e DCOM.
   Unless a developer get the comparision between two technologies he/she may not choose the new one.

   Hello, I would like to remote an interface to a client-activated object.  This sample, and others I've seen assume a singleton/single-use object, which won't work for my application.  Or, is there no way to do CAO's with interfaces?  Help!  Thank you.

   Hi,
   

   
   Can you please pass me the Client application source code for your article .Net Remoting. I think you forgot to upload in your site at http://www.developerfusion.com/show/2082/3/
   

   
   Can you please forward the source code to my e-mail ID @ r_nazermd@yahoo.com
   

   
   Thanks and Regards

    Good article.  The client side code was missing until I went to the printer friendly version.  I ran the code and it worked as expected.  
    

    
    I have a couple of questions about interfaces.  Is it possible to initialize a type "such as byte [] array" within the main program and allow the interfaces to access that initialized type so that the clients could do something with it?  I thought that the use of interfaces would be a good tool for clients to use to get information from a server that is constantly polling external data.  The only examples that I have seen so far, show me that the main thread is completely separate from the interfaces.  Is this true?
    

    
    Thanks,
