Chapter 4, Problem 4PC

Weekly Temperatures with Validation

Programming Challenge 3 in Chapter 3 asked you to create an application that asks the user to enter weekly temperature readings over a five-week period. In this version of the application, you will perform more detailed input validation. Once the values are entered and the user clicks the Calculate Average button, check each input field for two criteria:

1. The temperature must be numeric
2. The temperature must be between −50 and +130

If any single input field is incorrect, you must identify the field and the error by printing a message in the StatusStrip control and moving the focus to the incorrect field.
