Lab Problem: 1. Yo u will copy/open the Calories project from the K: drive to your H: drive or flash drive. Read problem #4 found on page 391 to complete this application. A method for validating the two inputs has been started for you. Instead of using the MessageBox class to display error messages for user input, you will use the ErrorProvider Component located in the toolbox. An example of using this control can be found on pages 729-731 of textbook (Appendix B). What needs to be displayed in the label named IblCalories? The following 2 line.. Calories from fat: 99 Calories from carbs: 99 Please note: The icons that appear for the ErrorProvider control when an error occurs will have to be cleared somewhere in your code by calling the Clear) method. Assessment Grader: --(2 pt) Validate method works correctly with the ErrorProvider component. (2 pt) Method for calculating calories from fat. _ (2 pt) Method for calculating calories from carbs -_ (2 pt) Output is displayed correctly for calories from fat and carbs. --(2 pt) Application logic/test results
