I lost the source code from one project I did on the company I'm working for and haven't been able to find a Visual Basic 6 decompiler; does that even exists?
I only have the EXE that I've rescued from a user's machine.
This question is related to
vb6
decompiling
Did you try the tool named VBReFormer (http://www.decompiler-vb.net/) ? We used it a lot the past year in order to get back the source code of our application (source code we had lost 6 years ago) and it worked fine. We were also able to make some user interface changes directly from vbreformer and save them into the exe file.
Yes I think You can get it download and separately its Help files from: vbdecompiler.org Site. and there is a Video on YouTube which explains how to Use it to Get the Code from an exe file and Save it. I hope that I helped.

This link provides a lot of resources for VB6 Decompiling, but it seems like it will depend greatly on what you DO have (do you still have the pre-link Object code [EDIT: er... p-code I mean], or just the EXE?) Either way, it looks like there's something, take a look in there.
I have used VB Decompiler Lite (http://www.vb-decompiler.org/) in the past, and although it does not give you the original source code, it does give you a lot of information such as method names, some variable strings, etc. With more knowledge (or with the full version) it might be possible to get even more than this.

In my own experience where I needed to try and find out what some old VB6 programs were doing, I turned to Process Explorer (Sysinternals). I did the following:
This didn't show the actual functions, but it listed their names, folders of where files were being copied from and to and if it accessed a DB it would also display the connection string. Enough to help you get an idea, but may be useless for complex programs. The programs I was looking at were pretty basic (no pun intended).
YMMV.
