For information on Windows Sockets, including an explanation of the socket concept, see Windows Sockets: Background.Sockets Programming ModelsThe two MFC Windows Sockets programming models are supported by the following classes:CAsyncSocket This class encapsulates the Windows Sockets API. CAsyncSocket is ...
before the .NET, network programming is based on theWinsock/Winsock2that uses the C codes (standard C + Microsoft extension for C). Winsock 1 is based on theBerkeley Socket. The Winsock2 codes contains theWin32

Another point of this example is that when the socket application on the other end of the communication is a non-MFC application, you must avoid doing something like the following: ar << pMsg; wherepMsgis a pointer to a C++ object derived from classCObject. This will send extra MFC infor...
