The only Decompilers are for VB 3 and lower according to the following website. I've been using VB for years and I've never heard of a newer one for VB 4,5, or 6.

No VB Decompiler for VB6:

VB 3.0 Decompiler:

Wow, didn't believe this was possible, I suddenly feel very vulnerable.

Luckily, it doesn't seem to be able to extract much of the code.. the odd variable name here and there.

I suppose it could be very useful for re-building lost projects... assuming you remember all the code.

Bill Gates is the only person that I know for a fact has a VB6 compiler.  Lots of luck trying to get a copy of it from him.

Hi,

Open new project and then its properties (menu Project -> ProjectName properties), select Compile tab.

Here you can clearly see that decompiling is impossible for most of VB6 projects at least because default setting is "Compile to native code".

P-code means that VB will build special section describing each program step in VB commands, native code means that all properties and methods will be totally represented with assembler. And after that any optimization will completely destroy vb-like code organization.

Actually, this is quite like when you go for shopping: you will achieve some result, but you can perform it in many ways, so it is impossible to find your actions order having only results.

As an example, it is quite possible that following two code will be compiled to the same native code:

'snippet 1.
i = 1
a = "abc"
b = ""
While i<11
  b = b & mid(a,1,1)
  i = i+1
Wend

'snippet 2.
a = "abc"
for i = 1 to 10
  b = b & left(a,1)
next

Hope this explanation will help.

Sincerely,
Crin

This question about a VB6 decompiler turns up a lot in Newsgroups.  Bill Gates really does have a fully funcional VB6 decompiler.  However, aside from his decompiler I seriously doubt that there is anyone out there that has written a true VB6 decompiler capable of faithfully reproducing 100% of all the source code from any program.  Depending on your idea of what a "corret answer" to the question would be either myself or hes shoud be awarded the points.

Hello,

Regarding answer: there are NO VB6 decompiler except for the projects compilled to P-code or with full debug info (using appropriate settings in project properties). Otherwise it should be possible by some number (say 5) get the formula which produced that number (such as 2+3 or 10/2).

With points issue - personally I don't care, so it is up to you.

Sincerely,
Crin

If you persue the article located at the link hes mentioned: http://www.vbtechniques.com/content.asp?a=co&cID=859  you will notice that the article says, "After doing a bit of research, it appears that there no longer is a VB6 decompiler available for recent versions of VB6. At one point, a company called AshSoft had one; however, they don’t seem to exist any longer."  This means that at one point in time there actually existed a commercially available VB6 decompiler.  However, neither the company nor the program currently exist.  This article provides further evidence for my argument that the only bona fide copy of a VB6 decompiler rests in the hands of Bill Gates.
