Codex In-Depth AI Coding Agent Tutorial: Quick Start to AI Programming and Desktop Development

Course Overview

This set, "Codex In-Depth AI Coding Agent Tutorial", is a complete, systematic hands-on course covering AI coding + advanced C++ + MFC desktop development + DLL low-level development + game reverse engineering. It moves from shallow to deep: first students master the cutting-edge Codex AI coding agent, wiring up LLMs, office automation and API development; then it strengthens core C++ syntax and advanced OOP, and makes students fully proficient with MFC controls and graphics development; finally it lands DLL development, DLL injection, process enumeration and privilege escalation, and uses game reverse cases to teach finding calls, base-address traversal, data reading and binary-tree traversal.

The whole course is hands-on driven — from efficient AI-agent coding, desktop UI development and low-level library development to reverse debugging, memory analysis and game-feature implementation — fully linking "AI-assisted coding → app development → low-level advancement → reverse practice". It suits both beginners and advanced learners: you learn to write code efficiently with AI tools while solidly mastering Windows desktop development and reverse-engineering core skills.
