FoxDev Studio

Visual FoxPro has remained unchanged since its version 9 release, with a 32-bit, web-based foundation. Four key components enable this evolution: a battle-tested project that brings VFP 9 to 64 bits, an open runtime capable of loading 64-bit libraries, and a compiler and bytecode interpreter written in Rust and compiled to WebAssembly.

This setup allows FoxPro to run on any machine where the application is executed. The editor checks code as it is typed, ensuring that any underlining by the compiler matches the runtime's refusal. A running program is organized as a fiber, yielding work to the machine's processor when needed and returning the result promptly. MESSAGEBOX() no longer freezes the window behind it, READ EVENTS waits without consuming resources, and SetFocus triggers GotFocus as it always has.

Visual FoxPro forms are live trees of objects, with properties drawn directly from the tree by React. Each object monitors only itself, preventing sluggish repaints on dense screens. The .fll image is a 32-bit file, and every process within a 64-bit application is 64-bit, preventing internal libraries from being opened. SET LIBRARY TO initiates a small 32-bit process to manage external libraries, with synchronous calls to ensure timely responses.

The runtime's compatibility with real libraries, such as encryption, FoxTools, and Microsoft's API samples, ensures seamless integration. Visual FoxPro maintains its original functionality while incorporating FoxScript, which allows for executing blocks later and handling web requests. The language remains consistent, with FoxScript adding functionality without introducing a second language or separate service.

All aspects of the product, including those still in development, are meticulously documented and updated continuously.
