DLLBinder Example - Chatterbox
Chatterbox is a distributed message delivery system that enables processes to interact locally or
across a network. The application could form the basis of a real-time chat forum; interactive gaming
environment; secure intranet email service and so on. But before you start sending us emails telling
us about Flash Communication Server MX, please remember that chatterbox is intended primarily as
example that demonstrates how to use the DllBinder Pro XTRA. In particular it is a demonstration
of how to make asynchronous API calls. That said, it is also the case that access to a low-level API
such as WinSock provides a large degree of flexibility that should hold plenty of appeal for the
professional developer.
To use this code, make sure you have downloaded the DLLBinder Pro V1.0.0
and String Handler V1.1.0 XTRAs. Then download file chatterbox.zip
Feel free to make use of this code in any way you want. If you make any great
improvements, please send us a copy. Or if you have any other examples you would
like to appear in these LIBRARY pages, please send it to
info@the-mindseye.co.uk

At the lowest level three parent scripts are provided that are intended as generic wrappers for a
portion of the Win32 Sockets API:
This script encapsulates the TCP client. It maintains a connection to a specified port on a specified host machine.
External API:
new(strHostName, nPort)
CloseConnection()
OpenConnection()
ReceiveStream()
SendStream(oStream)
GetStatus()
WSAStartup()
WSACleanup()
This script encapsulates the TCP service. It listens for new TCP client
connections on a specified port.
External API:
new(me, nPort)
ReceiveNewConnection()
StartListening()
StopListening()
GetStatus()
WSAStartup()
WSACleanup()
This script encapsulates a single TCP service-side client and is an integral part of the server-side service.
A new child instance of this script is created for each new connection socket handle received by the
sctTCPService TCP listening service.
External API:
new(hSocket)
CloseConnection()
ReceiveStream()
SendStream(oStream)
