In the Design view of the BedAndBreakfast project in the Visual Studio IDE, drag a CheckBox onto the Form below the Check our rates Label. (See Figure 12-35 for its approximate placement.) Change the Text property of the CheckBox to Belle Aire Suite. Change the Name of the property to belleAireCheckBox. Drag a second CheckBox onto the Form beneath the first one.

In the IDE adjust the size, position. or font of any controls if you think your adjustments would improve the program's appearance, and then test the program again 10. When you dismiss the BelleAire Form, the BelleAire CheckBox on the Bed and Breakfast Form remains checked. To see it appear as unchecked after its Form is dismissed, dismiss the program's main form (Bailey's Bed and Breakfast) to end the program. Then, add a third statement within the if block in the CheckedChanged) message as follows belleAireCheckBox.Checked false; That way, whenever the CheckedChanged method executes because the belleAireCheckBox was checked, it will become unchecked. Save the project, and then execute it again. When you select the BelleAire CheckBox, view the Form, and dismiss it, the CheckBox appears unchecked and is ready to check again. Dismiss the BedAndBreakfast Form 11. Click Project on the menu bar, and then click Add New Item. Click Windows Form, and enter its Name: LincolnForm. Click the Add button, and when the new Form appears, its Name and Text properties will have been set to LincolnForm. Change the Text property to Lincoln Room.

For example, the prizes might be a new car, a big-screen TV, and a live goat The player chooses a Button, and then one of the two other prizes is revealed; the one revealed is never the most desirable prize. The user then has the option of changing the original selection to the remaining unseen choice. For example, consider theseto game scenarios: game, three prizes of varying value Suppose that the most valuable prize is randomly assigned to the first button. Ii the user chooses the first button, reveal either of the other two prizes, and ask the user if he wants to change his selection. Suppose that the most valuable prize is assigned to the first button, but the user chooses the second button. Reveal the third prize so that the most valuable prizes location is still hidden, and then ask the user whether he wants to change his selection. . . After the user has chosen to retain his original selection or make a change, reveal wht he has won
