A few coding questions

Question

Programming

Hello, I have a few noob questions.
1. What is displayed when, roughly speaking, I open an .exe through notepad?
2. Is it possible to change this code in any way?

Answer 1

Exe file is in PE (Portable Executable) format, like dll, for example.
1. MZђ and all sorts of rubbish. To be more precise, ASCII interpretation of binary data (service headers, resources, code, data section). Well, i.e. rubbish. Binary files should be opened in HEX editors.
2. Yes, through a HEX editor. The structure can be googled for "pe file format". In addition, resources can be edited using res hacker. If you need to change the code, you need to use a disassembler.

Answer 2

1. Contents of the PE file: ru.wikipedia.org/wiki/PE
2. Yes (subject to a number of conditions).

Answer 3

A very strange question with interests in the profile: programming, networks, hacking, and game development.
