Video Bonanza Part five Visual Basic 2005

Modify the case study project from the previous Video Bonanza to use menus and a function procedure. Refer to the previous Video Bonanza for project specifications.

Use a function procedure to calculate the rental fee based on the type of video.

The Help menu About option should display a message box with information about the program and the programmer, The Color option should change the background color of the form; the font changes can change the control of your choice.

Menu:

Optional extra: Set keyboard shortcuts for the menu commands.

This is the previous specs from Video Bonanza Part 4 Visual Basic 2005

Design and code a project to calculate the amount due for rentals. Movies maybe in VHS (videotape) format or DVD format. Videotapes rent for $1.80 each and DVDs rent for $2.50. New releases are $3 for DVD and $2 for videotape.

On the form include a text box to input the movie title and radio buttons to indicate whether the movie is in DVD or videotape format. Use one check box to indicate whether the person is a member; members receive a 10 percent discount. Another check box indicates a new release.

Use buttons for Calculate, Clear for Next Item, Order Complete, Summary, and Exit. The Calculate button should display the item amount and add to the subtotal. The Clear for Next Item clears the check box for new releases, the movie title, and the radio buttons; the member check box cannot be changed until the current order is complete. Include validation to check for missing data. If the user clicks on the Calculate button without first entering the movie title and selecting the movie format, display a message box.

For the Order Complete button, first confirm the operation with the user and clear the controls on the form for a new customer.

The Summary button displays the number of customers and the sum of the rental amounts in a message box. Make sure to add to the customer count and rental sum for each customer order.
