You don't convert an exe to code.

You need to decompile or disassemble it.

So how can I get to the source code from the .exe program? (I am not the original poster, but I have the same problem...apparently.)

The .exe doesn't contain any of your original source code anymore. It is compiled to Hexadecimal numbers and can't be converted back.
If you could, then everybody could modify the code of your program and distribute his/her own version.

Maybe if you are an extremely skilled expert hacker and can read Hexadecimal code (that's mental :crazy: ), you can figure out what the original source code was, otherwise it's not possible

There are some decompliers available on the web. I tried some before to decomplie some of my own apps and they were very good. I cannot recall what they were called. you normally have to pay but can test a small portion of the app for free.

yup! you need a decompiler to do this job. This kind of process known as reverse engineering. It means, we are moving backward through the process. it can be done but not too easy...

i ever read an ebook written by someone about this. i can't remember the title and the author. however, maybe you can search it from knowfree.net if i'm not mistaken. i read it a year ago. the ebook is about on how to decompile viruses (.exe) made by visual basic to search for strings. maybe it'll help. there is an added thing; also in vb which can help you to get the source code.

Here's some extra info:
There are plenty of free tools that successfully decompile VB5 and earlier versions.
VB6 so far cannot be 100% decompiled while all .NET languages can be decompiled correctly.

If you followed the link that I provided, you would see that when you disassemble or decompile the output provided is assembler code, not hexadecimal. I think that you are referring to opening a binary executable file with a hex editor, which is a world of difference.

VBDE.exe is a widely spread decompiler (it has no other name, but always seems to have that title. No icon, just default like a .com or .pif file)

It decompiles vb6 to the point where you have all of the API calls, function names and arguments, but none of the actual CODES for each block...

there are also a couple of VB6 decompilers on planet source code, they mostly only decompile to specefied offsets and no further though.


Anyway, Decompiling of other people's software is USUALLY illegal, so don't go trying that, eh? :)

Wew....

Even it sounds hard, it's still illegal..
Haha...

I'm glad my future dream to be a programmer, not a hacker..
