Hello, if you want to be a hacker, you must have a good understanding of computer technology. Mathematics is the soul of computer. I suggest you upgrade your skills according to the mode of university training, and learn about mathematical analysis and discrete mathematics first. On this basis, learn C, c++, followed by data structure, algorithm and operating system, which is the most basic. If you master these, you can develop into the network and master some firewalls, tcp/ip, etc.

You can still give personal advice about VB. His design ideas and code style are not very good. The main reason is that this is a relatively advanced language. The high-level language here is mainly oriented to the specific operating system windows, and it is completely object-oriented, which is not conducive to the improvement of your computer technology.
