Last January, I fell victim to some RansomWare. :(
I managed to recover most of what I lost from backups, but one program I wrote was up to v4.0.5 and the only source code I was able to recover was from a months-old backup of v4.0.3.
Is there a way to decompile the v4.0.5 exe back to the original VB source code? (I've seen decompilers for C# but not VB.) TIA

I know this post is old, but recently with Claude 3.7 a vb .exe was decompiled and re-written into python. Maybe Claude could help in cases like these?
Best visual decompiler is dotPeek from JetBrains and it's free.
You can try tools like ILSpy
Thanks. I was hoping for something that could decompile to VB so I could compare my 4.0.3 source code side-by-side to the decompiled version looking for changes, but I'll take what I can get.

Try the older version of ILSpy: 2.4.0.1963.
Big thanks. The decompiled code doesn't seem to like VS2019, and the resulting source contains a lot of extraneous info, but at least now I can compare my old code to the lost/newer version in Notepad++. Excellent.
I had to dig to find old v2.4, as ILSpy is up to v6 now, but if anyone reading this in the future needs the link, they'll find it here.

You are a hero, thank you for not just saying "nvm, found it". I appreciate you!

I created a program for financial accounting
in the meantime, my disk with the working versions got damaged.
I also have a bug in the program. I tried the decompile when debug option. I find an error and delete the entire procedure, but I don't know how it has an effect on the executable program.
I'm asking for help
