Project Name: Twinbasic Diagnostic Tool - By woeoio
Description: 🏆 A Windows system diagnostic tool built with TwinBASIC, providing real-time monitoring and multi-format report export capabilities. Inspired by Linux's htop tool, featuring a modular architecture design and running completely independently without any external dependencies.
Reported Diagnostic Categories:
- ✅ Operating System Information - Windows version, build number, architecture, computer name, username
- ✅ CPU Information - Processor name, core count, architecture, frequency, revision
- ✅ Memory Usage - Physical memory, virtual memory, page file, memory load percentage
- ✅ Disk Information - All logical drives, disk space, usage rate
- ✅ Process Information - Running process list, PID, thread count, total processes
- ✅ Environment Variables - System environment variables (such as PATH, etc.)
- ✅ System Uptime - System runtime since boot
- ✅ Locale Settings - Language region, code page, time zone
- ✅ Network Configuration - Hostname, IP addresses, network adapters
- ✅ Installed Runtimes - .NET Framework, .NET Core, VC++ Redistributable
- ✅ CPU Real-time Load - Dynamic CPU usage monitoring

📊 Detailed Evaluation Criteria (@ai/002.md:43-55)
1. 📈 Practicality of Reported Information
Implementation Highlights:
- 🎯 11 diagnostic categories - Far exceeds the competition's "at least three categories" requirement
- 📊 Dynamic + Static data separation - Three refresh modes: Static/Dynamic/SemiDynamic
- 🔄 Summary mode support - Some collectors support lightweight summary data for better performance
- 📏 Smart formatting - Uses
FormatHelperfor friendly display of byte counts and time - 📋 Multi-format output - Supports TEXT, JSON, and HTML report formats
- 💻 Dual-mode operation - Supports double-click to start real-time monitoring and command-line file export
Usage Methods:
🖱️ Method 1: Double-click to start (Real-time monitoring + Interactive mode)
# Double-click diagnostic.exe directly or run without parameters in command line
diagnostic.exe- 🎯 Enters real-time monitoring interface, automatically refreshes system status every second
- ⌨️ Supports interactive hotkeys (F1/F2/F3/F4/F10/Q/Arrow keys, etc.)
- 🔄 Graceful exit with Ctrl+C or press Q/F10
📤 Method 2: Command-line file export (Batch report generation)
# Export plain text report (for scripts/batch files)
diagnostic.exe /text > report.txt
# Export JSON format (for programmatic parsing)
diagnostic.exe /json > report.json
# Export HTML report (for browser viewing)
diagnostic.exe /html > report.html
# Get help information
diagnostic.exe /helpUsage Scenarios:
- 🔍 Daily monitoring - Double-click to start, view system status in real-time
- 📊 Troubleshooting - Export reports for historical data analysis
- 🤖 Automation scripts - Combine with command-line export for periodic diagnostics
- 📧 Technical support - Export HTML/JSON to send to technical teams
2. ⚡ Performance Optimization
Technical Implementation:
🎯 Refresh mode classification:
Static- System info, CPU info, etc. (fetched once)Dynamic- CPU load, memory, processes, etc. (refreshed every second)SemiDynamic- Disk, network (optional refresh, changes slowly)
📊 On-demand data collection:
vb' Real-time monitoring only collects summary (fast) engine.RunAll(True) ' useSummary = True ' Export mode collects complete data engine.RunAll(False) ' useSummary = False🚀 Generic result containers -
DiagnosticResult(Of T)avoids code duplication🎨 Double-buffer rendering -
cConsoleBufferreduces screen flicker
3. 📦 Minimal EXE File Size
Optimization Strategies:
- ✅ Zero external dependencies - No third-party libraries
- ✅ Pure WinAPI calls - Direct system API calls, no intermediate layers
- ✅ Modular design - Features loaded on-demand
- ✅ Avoid redundant code - Use generics to eliminate duplication
Expected Result: Compressed EXE should be in the ~200-400 KB range

🎯 Summary
This project demonstrates TwinBASIC's powerful capabilities through:
- ✨ Elegant architecture - Modular, interface-driven, separation of concerns
- 🚀 Performance optimization - Three-level refresh modes, summary data, generic reuse
- 📦 Zero dependencies - Pure WinAPI, no external libraries
- 🎨 Modern features - Generics, delegates, interfaces, Return, short-circuit operators
- 📖 Comprehensive documentation - Clear comments for every class and method
- 🧪 Clever API usage - RtlGetVersion, GetNativeSystemInfo, etc.
- 📊 Rich functionality - 11 diagnostic categories, 3 export formats
- 🔄 Extensibility - Easy to add new collectors and formatters
- 💻 Dual-mode operation - Supports double-click real-time monitoring and command-line file export
- 🎯 Multi-UI architecture - Core abstraction layer supports Console/GUI/WEB multiple callers
The project not only meets all competition requirements but also demonstrates professional software engineering practices and TwinBASIC's modern language features. Both the console library and diagnostic object packages can be independently extracted and shared to the TwinBASIC Package Manager, contributing reusable components to the community. Future plans include further abstracting the core implementation layer to support multiple UI callers (Console TUI/Native GUI/Web WEBUI), enabling broader application scenarios.
