VB Auto Center Chapter 4 Visual Basic

Create a project that determines the total amount due for the purchase of a vehicle. Include text boxes for the base price and the trade-in allowance. Check boxes will indicate if the buyer wants additional accessories: stereo system, leather interior, and/or computer navigation. A group box for the exterior finish will contain radio buttons for Standard, Pearlized, or Customized detailing.

Have the trade-in amount default to zero; that is, if the user does not enter a trade-in amount, use zero in your calculation. Validate the values from the text boxes, displaying a message box if necessary.

To calculate, add the price of selected accessories and exterior finish to the base price and display the result in a control called Subtotal. Calculate the sales tax on the subtotal and display the result in a Total control. Then subtract any trade-in amount from the total and display the result in an Amount Due control.

Include buttons for Calculate, Clear, and Exit. The Calculatebutton must display the total amount due after trade-in.

Hint: Recall that you can make an ampersand appear in the Text property of a control by including two ampersands.
