how to convert dot EXE to source code

how to convert dot EXE to source code
1 Solution
Not possible unless you are using VB3 or lower. There were some decompilers available for early versions of VB. For later version, certainly 5 and 6 there are no decompilers available. If you don't have the source code for the application you will not get it back out!

Probably difficult but possible get ready to do some hex dump sniffing!!!

Simple...get yourself an Intel chipset decoder, and convert each byte and its corresponding value bytes into their related VB commands.

What you'll end up with is something that will require a 500GHz processor to run.

Basically, if you want the original source code, you can't get it because compilers CONVERT source code into system-optimized code.  This is a one-way conversion.  To convert back, you would have to "de-optimize" which would produce a multitue of choices for any given command, meaning that the reverse compiler would probably have hundreds of trillions of possible variations for even small programs.

Your best bet is either to find a backup of the source code or to take the original specs and recreate the source from the specs...which will probably be more efficient that the original anyway.

If you mean .NET exe, there is a decompiler...
>>If you mean .NET exe, there is a decompiler...

True, though you dont get the original source, you get the intermediary source (MSIL) code, which is readable enough in itself (with some work).  MS was debating whether a decompiler should still be available...if I ever do any programming for desktop programs to release to the public under .NET, I would hope they removed that "feature".
There is some obfuscator, but it's not from MS and I didn't hear any feedback.

LSW IL-Obfuscator mangles class-names, field-names, method-names,
properties, namespaces and events of an MSIL Program, making it more
difficult to reverse engineer IL-Code.

LSW IL-Obfuscator 1.1 can be downloaded from

Maybe in next version MS will make code more secure.
So the .NET "compiler" works just like Java compilers, right?  You get in-between code which can then use a JIT compiler to operate on the local machine?

I agree.  The idea of open source is great for public projects, but is terrible for rewarding hard-working individuals.  And this concept is borderline open-source!
