Operation

The user configures the components of a computer system by selecting items from the combo boxes, radio buttons, and check boxes.

When the user clicks the Calculate button, the application calculates the price of the system by adding the cost of each selected component to a base price.

When the user closes the frame or presses the Exit button, the application exits.

Add a feature that indicates how changing each selection will affect the price. For example, if Windows 7 Ultimate is currently selected, change the text for the Windows 7 Professional label to Windows 7 Professional (subtract $100). However, if the Professional edition is currently selected, the check box for the Ultimate edition should read Windows 7 Ultimate (add $100).

Print a summary of the configuration to a Dialog Message Box when the user clicks the Calculate button.
