Question

how do you know which code piece of code was made first in a dll file?

Answer 1

So when someone has created an application they keep their source code inside .dll files and to view the dll files you need a dll opener. When i open to sstudy the code i see it is difficult to understand where the code was started by the author.

Answer 2

Can you explain yourself a bit more ? I think it is a good question, but I am not sure what you are asking.

Answer 3

Really you don't want to know.
Of course you want to know which features were added in which version. That is where version control is for.

But knowing which method before another method is not giving you the information.
A programmer head contains that is the real spaghetti.
When I program I use a structure but my programming is not structured at all. A bit here and there, after that fill the holes and fix the bugs.

If you have just the dll and no other information, you have to do reverse engineering.

Focus on functionality not on structure.
