I have Visual Basic 2010 and also bought a book to study and practice problems. I know how to add controls and assign properties but get confused with the coding part. Can someone help me understand this somewhat?

Here is one problem I am working on-

Write a program to make change for an amount of money from 0-99 cents input by the user. the output of the program should show the number of coins from each denomination used to make change.

Now I know what controls i need on the windows form but I am sorta lost on the coding to make this program work.
