Description:
Good VB decompiler.

The attached older trial version (3.7) was the last demo version of VBReformer that allowed changes to be re-compiled, although it is a decompiler of dubious worth, it's main useful purpose that I have found is in changing forms and dialog boxes - enabling grayed out functions, inserting text and enabling non working functions - it only will work with native VB apps it will not work with P-code, I've found it more useful than Olly and Smartcheck for instance you MAY be able to disable a serial number check. As you work with it you'll appreciate it's simplicity. Oh, and it will default to install in French, but the language can be changed under the "Fichier" menu.

Tool Updated: VB Decompiler

Listed in categories: Decompilers, Visual Basic Decompilers

Most recent version:
7.6

Most recent release date:
July 12, 2009

Description:
VB Decompiler is decompiler for programs (EXE, DLL or OCX) written in Visual Basic 5.0/6.0. As you know, programs in Visual Basic can be compiled into interpreted p-code or into native code.

Since p-code consists of high-level commands, there is a real possibility to decompile it into the source code (of course, the names of variables, functions, etc. will not be decompiled). VB Decompiler restores many p-code instructions and although there is a long way to the generation of the source code that can be compiled, the decompiler will make analyzing the program algorithm much easier and partially restore its source code.

If a program was compiled into the native code, restoring the source code from machine instructions is not possible. But VB decompiler can help to analyze the program even in this situation as well. It contains a powerful disassembler that supports Pentium Pro commands including MMX and SSE. It allows you to disassemble all functions. There is also a code analyzer that searches for all API function calls and string references in the disassembled code and changes them into comments for analyzed strings. In general, VB Decompiler is an ideal tool for analyzing programs and it is perfect if you lose the source code and need to partially restore the project.

Description:
P32Dasm is a Visual Basic 5.0/6.0 PCode + Native code Decompiler. It can generate String, Numbers, Objects, Import and Export function listing. There is also Jump calculator. For VB Native code executables are generated only MSVBVM, External calls and string references. Usefull for setting BPX, you don't need search in debugger where start some Command Button event. You can generate .map files, which you can import to DataRescue IDA (LoadMap plugin) or to Olly Debugger (MapConv plugin).

Tool Added: Wintruder

Listed in categories: .NET Debuggers, Ring 3 Debuggers, Visual Basic Debuggers

Most recent version:
1.0.0.1

Most recent release date:
October 17, 2008

Description:
Wintruder is an extendable debugger for Windows 9x and Windows XP.
By default, it includes debug interfaces for:
- Win32 Debug API
- Intel x86
- Microsoft VisualBasic p-code
- Virtual Dos Machine (XP only)
- Win32 Stealth (XP only)
- Intel x86
- Microsoft VisualBasic p-code
- Virtual Dos Machine
- Microsoft .Net (.Net 1.0 and up)
- .Net CIL

You can use Wintruder for free. For more information read license.txt. If this file does not exist, type wintruder.exe -l

This version of Wintruder is a development snapshot and far from being a final release.

Most important limitations:
- You may encounter several bugs and deficiencies.
- The use of debug information is limited to bare function definitions.
- The native .Net debugger is missing.
- The script engine is not really working.
- Much, much more…

By the way:
- The DiaDbg plug-in requires the Microsoft Debug Interface Access library. (msdia80.dll, msdia71.dll or msdia20.dll)
- To be more precise: None of the libraries Wintruder is bound to is included in this distribution.

Most recent version:
1.3e

Most recent release date:
Around 2001

Description:
Also known as "WKT Debugger".

At the time it showed up, the one and only P-Code disassembler / debugger mankind was able to use.

Before it, debugging of the P-Code (Runtime interpreted Pseudo-VB code) with ordinary disassemblers / debuggers was really pain in your neck. This one saved me a lot of time, and probably helped postpone my deportation to the psychiatric research facility.

Tool Updated: RACEVB6

Most recent release date:
June 9, 2008

Description:
RACEVB6 is a Visual Basic 6 P-Code analyzer. RACEVB6 can be used to investigate Visual Basic 6 programs compiled to P-Code. RACEVB6 will display not only such typical information as Project data and Form/Control GUI data, but will also make available Procedures names and offsets, their accompanying P-Code opcodes, extract any Pictures or Images contined within the program, and many other pieces of "buried" data.
