Create a VB application that lets the user enter his or her weight (in pounds) and height (in inches). If the user fails to enter numeric values, display an appropriate error message and do not attempt to perform calculations. The application should calculate the user's body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person's BMI is calculated with the following formula:
BMI = weight × 703/height2
