Decompiler of Visual Basic programs. Decompiling forms, pseudo code, native code procedures (with power Pentium Pro disassembler and emulation engine), .NET IL code.
Version: 10.8VB Decompiler is decompiler for programs (EXE, DLL or OCX) written in Visual Basic 5.0 and 6.0 and disassembler for programs written on .NET technology.

As you know, programs in Visual Basic can be compiled into interpreted p-code or into native code. .NET assembly always compiled to just in time compilable IL 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 and some functions will not be decompiled).
VB Decompiler restores source code from p-code as much as possible precisely. And after some modifications you may try to compile generated code.
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.
If a program was compiled to .NET assembly, decompiler will recovery all tables and modules in managed assembly and disassemble all methods, functions and events using IL disassembler. .NET FrameWork is not needed for decompilation. Decompilation supported on all Windows 32 bit operation systems.
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.
Version 10.8: A lot of updates
Version 9.9: Main interface completely redesigned. Now you can view both decompiled and disassembled code on one screen. You can also view and edit a file in HEX mode on the same screen. It's so nice and easy!
