Number Guessing Game Windows VB form

I need help on making a Guess The Number Game windows vb form . So far I have made a menu with different modes and done some labels and text boxes but I am struggling with the code and need assistance in improving it.

In the game the user must use their logic in order to guess a 4-digit number selected by the computer at the beginning of the game.

The number is formed with digits from 0 to 9; each digit appears once at most. This number is guessed by the user via multiple attempts.

An attempt consists in a proposed number, selected by the user and the computer's reply. The computer must tell the user in their reply, how many digits has the user guessed on the same position, and how many digits has the user guessed on a different position.

Using information from the computer's reply, the user must guess the number using as few moves as possible

After the game is finished, ask the computer must ask the user for their name and input their score into a table and then show the high score at the start of the game Thanks!
