Write a program that does the same thing as this payroll program. Be sure to check that both the hours and pay rate are between 0 and 80. If either input is illegal, display an appropriate error message, and do not do the computation.
When it is working, turn in a screen shot showing an error message and the listing.
Hint: Check the validity of the data when the user leaves the TextBox. If the data is invalid, display an error message, and re-focus on the TextBox so the user can enter corrected data.
