🌐 Traffic Monitor

A modern, feature-rich Windows network traffic monitoring application — rebuilt from the ground up.

📖 What is Traffic Monitor?

Traffic Monitor is a lightweight yet powerful Windows application that monitors your internet and network traffic in real time. It displays live upload/download speeds directly on your desktop and inside the Windows taskbar — designed with a modern, clean UI that adapts to your system's dark or light theme.

Built with WPF on .NET 8, Traffic Monitor is fully portable, supports multiple languages including Arabic (RTL), and comes packed with advanced features like a built-in speed test, process-level network tracking, and detailed historical traffic statistics.

🔬 Technical Highlights

• Taskbar embedding via SetParent() Win32 API — the widget is a real child window of Shell_TrayWnd with automatic DPI-aware positioning
• Auto theme detection by hooking WM_SETTINGCHANGE from a hidden message-only window
• Named pipe IPC for single-instance enforcement
• Atomic history writes using .tmp → rename to prevent data corruption
• Per-process I/O tracking using GetExtendedTcpTable, GetExtendedUdpTable, and GetProcessIoCounters Win32 APIs
• Geo-aware speed test server selection using Haversine distance calculation against 30+ global Cloudflare edge locations
• RTL-aware toast notifications with slide-in/out animations that flip direction for Arabic
