Soda Programming Help

Okay so when a soda is purchased one of the buttons (button1 thru button8) is clicked, correct? So then checkMoney is executed. In checkMoney you need to add up all the money in the money.TotalAmount Stack to calculate totalAmount. Next you need to compare that to the ProductPrice for the selected drink; correct? I don't know if you want to do that in checkMoney or not. In the button click events you execute checkMoney; do you want checkMoney to check to see if the totalAmount is less than, equal or greater than the ProductPrice for the selected drink? Or in the button click event you can call a different function after calling checkMoney.

Note that whatever you do, dk, pt and pb must be a member of Form1, not local to Form1_Load. That is probably one problem / solution you need to understand. Then in each of the button's click event you know what drink to use.

Does that help?

Okay I looked at your code. You have an excellent start. You almost have it done. I will try to get time to look at it more later.

I like that you have objects (classes). That is good. I notice that Money is derived from Product. That seems strange to me. It might be correct for the way you are doing things but based on my initial quick look I think that is strange. I will look at it more later.

Okay so you need a way for money to be put in. You also need a way to keep track of how much has been put in. You need a way for the customer to select a purchase. When the customer selects something, you need to compare the amount they have put in to the cost of the item, then do something based on that. Have you done all that? If not, what part have you not done? Are you able to at least compare the amounts as I described?
