Chat Application problem (UDP)

Question

Hi  Initially I was creating a Chat program with both the server side and client side in ASP.Net Win forms (C#) They were working great but I had to change the client side to a web form. I had to do minor adjustments and it compiled correctly. (using UDPClient) However in terms of communication the web form (client side) can send data to the server side but when the server side tries to send data to the client side I received this error an unhandled exception of type system.runtime.serialization.serializationexception occurred in unknown module. additional information: the type system.web.httpexception in assembly system.web version1.0.5000.0culture=neutralpublickeytoken=b03f5f7f11d50a3a is not marked as serializable The source codes are similar to the ones in this link http://www.vbip.com/books/1861007353/chapter_7353_05.asp Please help!

Hi I have traced the error to the line in the listener method buffer = m_client.receive(ref m_RemoteEP); whenever the server application (the windows form) sends some data to the client side the client side will show this error. Any help is appreciated!
