Simple LAN messaging client-server application.
| Download LANMsg desktop application (Windows 64bit) | Download LANMsg source code (Lazarus/Free Pascal) |
Description: LANMsg is a very simple networking application that, on a local TCP/IP network, allows to send
messages from one computer to another. The messaging system is implemented as client-server application, i.e. the different computers (clients) connect to one specific
machine (the server). If they send a message (to another client identified by its IP address), the message is actually send to the server, which then relays it to the
other client.
LANMsg is a very simple application, that was never really intended to be available as download here. In fact, it's the final client and
server examples of my tutorial Introduction to network programming using Lazarus/Free Pascal. As there seems
to be a rather great interest in the source code, and as the samples actually are fully functional applications, I decided to place source and executables together with my
other applications.
Improvements/Extensions: Have a look at the tutorial mentioned above for suggestions how to transform the programs into "real" messaging
applications...
Free Pascal features: Lazarus network programming, Lazarus client-server applications, Lazarus TCP/IP applications. Usage of the
lNET package, usage of the TLTCPComponent class. Connecting to a server application, sending data between a client
and a server application.
