Create a Windows Forms application. Use the following names for the project and solution, respectively: Hales Project and Hales Solution. Change the form files name to Main Form.vb. Change the forms name to frmMain. Create the interface shown in Figure 4-56.

The interface contains a checkbox, a group box, four radio buttons, two labels, and two buttons. Be sure to set the tab order. The prices of the comforters sold at Hales Department Store, as well as the shipping fee, are included in Figure 4-56. The shipping fee is charged only when the customer is not taking advantage of the store pickup option. The Display cost button should determine the comforters price and whether to charge a shipping fee. The button should display the cost of the comforter (which might include the shipping fee) with a dollar sign and two decimal places. Be sure to code the CheckedChanged procedures for the radio buttons and checkbox. Save the solution and then start and test the application. (The cost for a Queen comforter that will be picked up at the store is $49.99; if it is shipped, the cost is $54.99.)
