Editor's review

You may have different programs with different extensions like DLL, EXE, OCX, written in the visual basic or .NET framework. This automatically means that these programs are compiled in above mentioned languages. A programmer may be interested in breaking this program in its original form and look for the programming algorithm of these programs. A visual basic program is also compiled in p-code which consists of many high-level commands. In this case, you need an application for accurately decompiling this program as far as possible into it’s source code for modifications in the program and recompilation. VB Decompiler v.8.2 is a valuable application for such purposes.

VB Decompiler by DotFix Software is a powerful decompiling tool for programs written in VB 5.0 and 6.0 languages and .NET technology. The program offers a user friendly interface with an objects tree on the left hand side window pane and thr relevant content of each object displayed in a display window in the center. You just have to select the required file in the program and hit the ‘Decompile’ button and this application will show the objects and source codes of the program. It features powerful and accurate disassembling and emulation capabilities even for programs written in native source code. Thus you can decompile and analyze such programs also. It may have some failures in assembler code optimizations and incorrect instruction generation but uses some of the most powerful algorithms for decompilation of programs. It also has an IL disassembler which can recover tables, modules, methods, functions and events from a program written in .NET framework.

Overall, VB Decompiler v.8.2 is a powerful and fairly accurate application for decompiling programs written in VB and .NET. Hence, it receives a score of four rating points on the scale of five.

Publisher's description

VB 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.
