Doom Intergrated Editor (Doom Level Editor)

This is one of my first project as a programmer, the project's main goal was to make a user-friendly level editor for DOOM. I haven't touched this source for awhile as this project was abandoned later and never finished. This source will compile with no problem with Visual C++ 6.0, and there's a line in WinMain you can uncomment if you have a DOOM main WAD and then you will be able to see the textures displayed on the toolbar when you select a line. This code is currently very messy, but it can teach many programming techniques. It can help you learn how to read a large binary file such as the DOOM wads, it can teach you how to draw lines and different shapes with GDC, it can teach you how to write a full-blown Windows program without MFC, using the Windows API. This code can also teach you how to implement a large dialogbar, how to draw bitmaps and other types of images on a Window, open routines (Save not implemented fully), apply modes to your software, most of all, it's a fully-functional software coded in C++.
