The decompiler sees THISFORM.oleControl1.Object.DoSomething() but cannot recover the original control’s GUID or registration details. You need the original OCX file.
The US Copyright law (17 USC § 117) allows for a "backup copy" or modification of software to maintain functionality. If you own a license to the software (not just a runtime), and you need the source code to fix a critical bug because the vendor no longer exists, you have a strong fair-use argument. If you are decompiling a competitor’s app to steal features, you are going to lose in court. foxpro decompiler
ReFox is widely considered the industry standard for VFP decompilation. The decompiler sees THISFORM
It is important to note that no decompiler can reproduce the original variable names, comments, or formatting. However, a high-quality decompiler can recover the logic, functions, and database interactions with remarkable accuracy. If you own a license to the software
A FoxPro decompiler reconstructs source-like code from compiled Visual FoxPro (VFP) binaries (PRG, SCX/VCX, APP, EXE variants using VFP runtime). Decompilation can aid recovery of lost source, security reviews, or migration, but raises intellectual property and security risks. This report summarizes capabilities, typical outputs, legal/ethical considerations, technical challenges, and practical recommendations.

Unlocking the Past: A Deep Dive into FoxPro Decompilers For many developers and database administrators, Visual FoxPro (VFP) isn't just a legacy language—it’s the engine behind massive, mission-critical systems that have been running for decades. However, because VFP was officially retired by Microsoft years ago, many organizations find themselves in a bind: they have the compiled application ( .EXE or .APP ), but the original source code has been lost to time, hardware failure, or staff turnover.
