I have this random number generator and I want to change it to VB.net.
I am getting confused on how to auto save and to program it.

What I have tried:

import random

number_of_codes = 100000
code_file = "codes.txt"

with open(code_file, "a+") as file:
    for _ in range (number_of_codes):
        a=random.randrange(10)
        b=random.randrange(10)
        c=random.randrange(10)
        d=random.randrange(10)
        e=random.randrange(10)

        file.write("282460000" + str(a) + str(b) + str(c) + str(d) + str(e))
        file.write("\n")

print ("Done!")

Lets break this down into steps.
1. Open a file for writing
2. FOR loop
3. Random number generation
4. Writing to a file
5. Write a line to the console

To be honest, I didn't understand what the problem you have, but if you need to create the random number in VB.NET you can do it like this:

[EDIT]
You forgot a line of code.
[/EDIT]

Dim r As New System.Random()
Dim value = r.Next(10)

Python

a=random.randrange(10)
b=random.randrange(10)
c=random.randrange(10)
d=random.randrange(10)
e=random.randrange(10)

file.write("282460000" + str(a) + str(b) + str(c) + str(d) + str(e))

Using 1 random function per digit is not a clever idea, it will not improve randomness of generated numbers. Random functions exist since beginning of computers and are perfectly capable of generating 5 digits numbers.
If your problem comes from leading zeros, there is solutions:
- when you convert number to string, you can use formatting (language dependent)
- or without formatting
