After collecting and analyzing of sent to us users' opinions about this program it takes our editors award with a rate "5". This means that this program is popular and was found as convenient and useful.
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.

Version: 7.5
The demo version does not demonstrate the format of possible code (just suggest for using Pro version, it should display some fake code to show the format used by the pro version). I was not convinced that the pro version will display the code in the format that I can read.
I deleted the source code which contains last 2 weeks of my work and I have only the executable. So I need to have a tool which could provide me more details so that I can recover my lost code.

Version: 7.1
I tried the free version but it did not do what I wanted - decompile to something I could load into VB6 to try and recover a programme I have lost the source code for. I will not buy the full version unless I can try it first to see if it does what I want.

Version: 7.1
It works in parts, but not 100% decompile the code leaving some pieces of code difficult to understand because they are in assembler. But what is promised to those who need a minimum of decompilation is a great tool.

Hi,
I can't execute your decompilador on my windows server 2008.
What can I do to achieve run?
Regards

Version: 3.9
Used the decompiler to track program flow through a VB6 exe file, to assist documenting a program bug that had been observed, after the software vendor was unable to replicate the problem.
Decompiler worked fine and installed ok.
A once-off use of the trial vesion.

Version: 3.9When I try to decompiler some .dll files, it will hang -- system take very long time to process, but never finish the job...
I'v been try for three different .dll files, two of them will hang.

Version: 3.9It's OK, the programme extracts the form names and structure of the VB programme. But as U mentioned for DEBUGGING some RUN TIME ERRORRS it is not providing the details of SOURCE CODE.

Version: 3.9I test it by some VB6 programs, but it does not work properly!
It creates forms and project but NO codes!

Version: 3.9I have use in order to try the decompiler, but i have not what i was expected, program still have some assembly language
Ansewer of VB Decomp, 2006-11-20 05:13:45
Version: 3.9Thank for a good product.
I have tested for one of my exe creted fron vb6.0.
It got successfully dcompled,
but when i started to complie it again fron my VB6.0, It was giving
'Memory overflow' ERROR.
I am having 256 mb ram of win2003 server edition OS on a PIII 700 Mhz PC.
I would like to know that the same (or after a minor change of any object from any vb-form, not code change) project will be created again and can run fully as it was earler ?
Please send me guidence on these. Then only I can Review the product truely.
Thaking you,
Mahendra Mahidadia
VB Decompiler is only partially decompile code and only in Pro version. Compiling result code is not possible. Use VB Decompiler only to find bugs in your programs and for analyze code.

Version: 3.9
I lost sources of my VB6 project, compiled to P-Code. Pro verion of this tool recover more of needed code and save it to VB format. big thanx to authors for this great product.
Thank you.

Version: 3.9Forms were satisfactorily decompiled, classes were partially decompiled and controls were not at all. Maybe I haven't fully understood the differences between trial and full version, but I expected to have an idea about how controls were decompiled.
My final goal was being able to edit a Dll whose source code I haven't ever seen, even if in Assembler language. This way I cannot.
Maybe there's a too strict limit in the trial version.
Pro version decompile P-Code to source! native code onlly disassembled.
