💬 CommunicationSystems — IPBox

A client-server communication application built with a C++ TCP server and a C# desktop client. Supports file transfer, real-time chat, and server status monitoring.

Technologies

• C++ — TCP server, Base64 encoding
• C# / .NET — desktop client (WinForms)

Features

• 💬 Chat — send messages in unicast (to a specific user) or broadcast (to all connected clients) mode
• 📤 File upload — send files from the client to the server
• 📥 File download — retrieve files stored on the server
• 📊 Server status — fetch real-time information about the server state (e.g. memory, CPU temperature)
• 🔐 Base64 encoding — used for safe data transfer over TCP
