Software used to decompile and analyze programs created in Visual Basic, revealing their source code and algorithms.

Decompiler for Visual Basic applications which provides an environment for performing debugging.

VB Decompiler is a powerful and advanced shareware visual basic decompiler app and developer tool, developed by DotFix Software for Windows.

The download has been tested by an editor here on a PC and a list of features has been compiled; see below.

Decompiler of Visual Basic programs. Decompiling forms, p-code, native code

Decompiler of Visual Basic programs. Decompiling forms, pseudo code (with parse opcodes to standard vb instructions and decompile objects references), disassembling native code procedures (with power Pentium Pro disassembler, supporting MMX and FPU instruction sets), syntax coloring in decompiled code, string reference list and search engine, fast decompiling speed.

If a program was compiled into the native code, restoring full 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 and emulator. This powerfull engine try to decode most assembler instructions to most likely VB commands. Of course, it fails on some optimizations of assembler code and sometimes generate not correct instructions. But at this time this is a best way to analyze native code applications.

VB Decompiler also decompile all GUI Forms and UserControls presented in file. For technical use decompiler may show offsets of all controls.

Features of VB Decompiler

  • Disassembles native code procedures.
  • Save decompiled data to single DB file.
  • Syntax highlighting in decompiled code.
  • Unpacks packed application (UPX, NSPack and other EXE packers).
