Can VB 6 be decompiled

[Adron]

Sounds like dotfuscator makes code inefficient, and sounds like reversing dotfuscated code just requires making a list of what changes they can do and reverse them. Just look at anywhere you see a lot of overloading and fix that...

Inefficient? Not really...maybe an extra step in compilation but that's it.

It's really no worse than everything being stored in eax, ebx, etc.

You could try that, but you still wouldn't have the originial function names.  I'm not saying its secure, but for non comercial applications I think it's fine.  You just have to be careful not to let it rename things that you rely on the names of; I ran into a problem with this when I accidentally allowed it to rename my CharacterClasses enumeration in a Diablo 2 character editor, when I frequently used the string representation of the enumeration value as a display.  "Character class: ÿ"  doesn't convey information too well.

You have no need for an obfuscator if you write open source code.  That's my solution

What, off opensource or closedsource?  I'm not sure whether you're making fun of opensource or vb or what.

In defense of opensource, it's great for personal projects but I can see how it would be a problem with commercial projects.

It obviously changes the program when represented as .net bytecode, adding new classes and more code. Are you saying that all of its changes can be optimized away when generating the machine-specific representation?

Ah, I didn't know .net stored the original function names in its compiled form. I had assumed any non-exported function/variable names were gone already.

I beleive you can ask Microsoft to do it, for a fee.

Wow after searching about a day straight for the reverse engineering and searching through many other boards I have concluded that their some decompilers but they aren't as great as you may think. There are 1 - 2 that are ever remotely decent one called VB RezQ but you must buy it for the full version and this will not show you functions of any sort and its really not what you want unless you truly want help to get your program back.

My Conclusion:
There aren't any REAL VB6 decompilers but there things that will help you if you need to find a properties of one of your controls.

Basically you won't find anything that'll be even close to the source in vb6 so don't waste your time since I have.
