what you need is a decompiler.

if you compiled your program into pcode, you will be able to decode the majority of your program, if it was compiled exe, then there is nothing you can do

There are machine code->assembly (de)compilers, there are some (de)compilers/descramblers that manage to produce Pascal, Fortran, C or Basic(!) code from assembly or machine code, but almost inevitably it will be as spaghetti as it can get, and not be very close to the original source, even if it is the functional equivalent (it will literally be the same actions performed). This because the (de)compiler/descrambler has to approximate the functionality based on patterns, since much data is lost in the original compilation. If it had any way of knowing that the code actually came from a certain version of a certain compiler at certain optimisation setting it would be capable of producing much better approximations.

There are different decompiler available for different programs

VB 6.0

VB6 decompiler

Hi Anant,

You can convert exe to source code by using VB Decompiler.

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.
