GETTING HELP:You may ask another student for help, but you must not copy their code. Failure of the course will result for the person giving the code and the person receiving the code.

REMEMBER: THE GRADES IN THIS COURSE ARE CURVED.

I can get limited help from other students. For additional help, I need to see Dr. Scanlan, or the tutoring center.

1. The GUI MUST look almost exactly like the one displayed below.

2. Use FormatCurrency() and FormatNumber() functions to display the amounts. Use dollar signs for Gross andNet pay and Totals only.

3. Use Me.Close to close the program

5. Use any picture of a coffee shop you can find bysearching Google Images.

6. If Hours worked are over 40 then the employee receivestime and one-half for the hours over 40.

10. You are to modularize the program according to the hierarchy chart below. The code for the Main Module and the Validate Data modules are given on the following slides.

11. Use lblLabel.Text = “” and txtTextBox.Clear() to clear labels and textboxes.

12. You may NOT use module-level variables. You must communicate between modules using arguments and parameters.

13. Use ByRef only when you are passing a value back to the calling module.

14. You must add a range test to the Validate Data module: Range: Hours Worked: 1 through 60 Range: Pay Rate: 10 through 15

15. You must use the code supplied on the next slides.
