Aristoline - TextSocket

Overview

TextSocket is and ActiveX component (provided by the SocketSet control) that enables the development of applications that use text based TCP stream communication or block based stream communication. Many of the TCP/IP protocol suite use text based communication (i.e. they communicate using lines of CR/LF terminated text). Examples of such protocols are SMTP, POP3, NMTP and FTP control connection.

TextSocket is derived from the Socket class and offers an interface specific to such protocols. It has the following features:

Supports asynchronous TCP stream sockets only.
Can be used to send lines of text, blocks of binary data or as standard stream socket.
Internal buffering ensures that whole lines/blocks of text/data are sent/received without any fragmentation. Your application does not have to handle partial sends/receives.
Lines/blocks of text/data are delivered to your application via the LineArrived event.
Asynchronous resolution of host name to IP address.
Event driven programming model.
Suitable for developing client and server applications.
Supports mainstream underlying API (accept, connect, listen, send, recv, shutdown).
