Accessory Prices: - Stereo System = $ Leather Interior = $ Computer Navigation = $1, Exterior Finish Prices: - Standard Finish = No additional charge - Pearlized Finish = $ Customized Detailing = $ Sales Tax -10% of (Selling Price + Accessories + External Finish – Trade-in Allowance) 3.Subtotal Subtotal = (Selling Price + Accessories + External Finish – Trade-in Allowance 4.Amount Due Total Price= (Subtotal + Sales Tax) Your Form must closely resemble this one: See the next slide for additional requirements. Note: You may use module level variables and constants. Radio buttons Check Boxes Don't forget this: VB Auto Center. TOTAL POINTS: 50 DUE: OCTOBER 28

FOR THIS ASSIGNMENT IGNORE item 1 BELOW. WE WILL ADD THIS FOR THE NEXT ASSIGNMENT. 1. Limit "Car's Sale Price" to $100,000. If $100,000 is exceeded, trigger an appropriate MessageBox and have the value re-entered. Limit "Trade-in Allowance " to $50,000. If $50,000 is exceeded, trigger an appropriate MessageBox and have the value re-entered. 2.Use good internal documentation. See class notes, and examples in this assignment. 3.Be sure to use the FormatCurrency function for dollar amounts and FormatNumber for other amounts. 4.Be sure to use the supplied values for module level variables and constants. 5.Use Option Strict On in your code. 6. You must use appropriate three-letter prefixes for variables, constants, and objects, such as Buttons, TextBoxes, etc. 7.Use good identifiers (constant names, variable names, object names, etc.). These should be as meaningful as possible and as short as possible, but as long as necessary. 8. Follow the outline for the program on the next three pages. You must use REGIONS. 9. Be sure to use effective test data. This will insure that the program works correctly. 10.Set up two click events that clear the appropriate input text box when clicked. This will allow easy re-entry of values if a typo is made. The click event must clear the textbox and reset the background color to white. 11. Declare all constants at the module level of the code. 12. Declare all variables at the module level. 13. Validate Data module must do the following: Set the textbox backgrounds to yellow when an error occurs. You must have a separate TRY/CATCH for each textbox Appropriate error messages must be given for invalid casts. The user must be informed as to which textbox caused the error. 14.The Prices below must be CONSTANTS.

Program 03 VB Auto Center Problem Ignore this line. It is from an older version of VB. You must use these modules and regions. TOTAL POINTS: 50 Change this to: “EXTERIOR FINISH CHARGE” because there is only one charge.

Programming Assignment 02 PART-2 VB Auto Center Problem You must use these variable names. You must use these constant names and values. Add this constant.

Programming Assignment 02 PART-2 VB Auto Center Problem You must use these names for the procedures. Change this to: ExteriorFinishCharge

Use this code for your Validate Data Module

Programming Assignment 02 PART-2 VB Auto Center Problem This is the procedure for selecting an Exterior Finish Charge Students: Note the Case Structure
