Windows underneath Windows

Surviving source
A window inspector, code generator and extensible developer tool—not just a cursor readout.
Its source follows the cursor to a live window handle, reads class names and captions, walks parent and child relationships, and generates FindWindow-style VB code. The options surface offers operations such as clicking or setting text; another path can apply selected operations through the RunCode companion.
Preserved .eas templates feed code-generation add-ins, while RunCode dynamically invokes code through a DLL interface. That is real extensibility, but not proof of a completely generic arbitrary-DLL plug-in system. Process, memory and advert subsystems make the application much broader than its name.
