Reverse Engineering Borland Delphi 7: A Decompilation Guide

1. Introduction

Borland Delphi 7 (released in 2002) represents a high-water mark for the Delphi programming language and the Win32 RAD (Rapid Application Development) environment. Applications compiled in Delphi 7 are native x86 code, but they differ significantly from C++ applications in how they link libraries and structure memory.

You can usually recover almost 100% of the visual forms (buttons, labels, layouts) as DFM files. Function Names: For "published" methods (like Button1Click borland delphi 7 decompiler

It was a custom inventory tool for a local hospital that had long since lost its source code, and Elias was their last hope for an update. Reverse Engineering Borland Delphi 7: A Decompilation Guide

Step 2: UI Extraction (Static Analysis)

Load the binary into IDR.

DeDe is the "old school" favorite. While it hasn't been updated in years, it is incredibly fast at extracting form information (DFM) and identifying the addresses of published methods. You can usually recover almost 100% of the

The Power of RTTI (Run-Time Type Information)

Borland embedded a substantial amount of metadata into Delphi 7 binaries. This was necessary for streaming components (.dfm files) and runtime type identification. Crucially, this RTTI includes:

They link visual elements (like a "Submit" button) to the specific memory address where its "OnClick" code begins. Class Hierarchy Reconstruction:
