Does anyone know/have experience with this programming, particularly in creating a class? I have a GUI form that has several options that a user selects from (by checkmark box). Each option has its own price.

For example: 80gb harddrive = $80, 120gb = $100, etc. This goes for a type of case and other computer components for building a computer.

I have three text boxes, 1 for a sub total, additional cose (for adding a tax) and total. When the user clicks on a Quotation button, these three text boxes will be filled with an estimate price. If the user is happy with the price, they can click on a Purchase button. Here I would want a message box to show "Do you want to purchase this system" with a yes or no option.

I have no idea how to do this. I have to create a new class and somehow initiate this class into the main code. Could someone with experience in VB provide a stepping stone for me.

thanks
