The Internet Component Suite is composed of various Internet components and applications. It is distributed as freeware with full source code for all Delphi and C++Builder versions. The sample applications exists in two forms: Object Pascal for Delphi and C++ for C++Builder. The components are written in Object Pascal native VCL which can be compiled by Delphi as well as C++Builder. There is a wiki under construction here where you'll find valuable documentation.

Below you'll find the links to download ICS/ICS-SSL distribution archives. You can find the latest source on the version control repository and an archive extracted daily from the repository here: ICS-V8.

TWSocket Basic winsock component. Fully event-driven and multi-thread safe. It supports TCP, UDP, SOCKS5 and can be used to build both client and server programs. Option: SSL support. Click here for a primer text about TCP and UDP.

TFingerCli FINGER client. Use it to retreive information about logged user connected to a Unix machine (or any other with a finger server).
TPing ICMP Ping support. You can Ping a host and get the resulting info.

Client5 A basic client program using TWSocket component. Use with any of the server applications described below.
TcpSrv A basic multi-user server. Start all your TCP servers from this sample.
DnsLook How to use TWSocket DNS lookup feature.
Finger A Finger client using TFingerCli component.
FtpTst A full featured FTP client based on the TFtpCli component.
FtpSrv A full featured FTP server based on the TFtpSrv component.
HttpPg Use THttpCli component to post some data to a web server.
HttpTst Basic THttpCli component use. No very useful, but demonstrate most component features.
WebServ A THttpSrv component is used to build a webserver.
MtSrv Basic multi-threaded server using TWSocket. Accept any number of simultaneous client, servicing each one in a thread. The base for any real world server. See also TnSrv (event-driven) and MidWare for a complete client/server framework.
NewsRdr A basic newsreader using TNntpCli component.
PingTst A ping program using TPing component.
MimeDemo Show how to use the TMimeDecode to decode EMails received with the TPop3Cli component. You can display or save the message and all its attached files.
Server A basic yet complete event-driven server using TWSocket. Can support any number of client. The server fetch some data from a TTable at client request.
MailRcv A basic POP3 client program. Demonstrate most TPop3Cli features. Quite useful. Can be the base for a real EMail program if merged with the MailSnd program (see below).
MailSnd A basic SMTP program (send mail). Quite useful. Can be the base for a real EMail program if merged with the MailRcv program (see above).

TnClient A full featured TELNET client program with ANSI terminal emulation.
TnDemo A TELNET client using a TMemo to display incomming data.
TnSrv A basic event-driven server. Can support any number of concurrent clients. The base for any real world server. See also TcpSrv, MtSrv (multi-threaded) and MidWare for a complete client/server framework.
TWSChat A full featured CHAT program, both client and server. It's a good demonstration for many TWSocket features.
UdpLstn A UDP server demo. It listen for UDP messages on a given port and displays them.
UdpSend A UDP client demo. It sends or broadcasts UDP messages to a given port.
SocksTst A simple client program showing how to use the SOCKS5 protocol to traverse a firewall or proxy like WinGate.
ConCli Actually 2 console mode applications showing how to use TWSocket into console mode client applications.
ConSrv Much like TnSrv sample program, but using console mode application (usefull to write a daemon or service).
IcsDll Shows how to build DLL with a TWSocket. The sample DLL connect to TcpSrv sample program to get date/time. A sample demo application shows how to call the DLL.
DynCli A very basic client program showing how to use a dynamically created TWSocket component.
