Me.Close() 6. txtTextBox.Clear() and lblLabel.Text = “” 7. Procedures, Arguments and Parameters, ByVal and ByRef 8.FormatCurrency() and FormatNumber() functions 9.Use Google for help on FormatCurrency and FormatNumber. DIFFICULTY LEVEL:DIFFICULT TUTORING CENTER IS NOW OPEN START ON THE PROGRAM NOW. Know Chapters 1, 2, 3, 4 and 6 for this program. Spring 2015

2 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.

3 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 and Net pay and Totals only. 3.Use Me.Close to close the program 5.Use any picture of a coffee shop you can find by searching Google Images. 6.If Hours worked are over 40 then the employee receives time and one-half for the hours over Note: There are changes on the form from Program #2. 8.The Clear Button clears all amounts, Radio Buttons, and CheckBoxes. 9.Be sure to use dollar signs for Totals, Gross Pay and Net Pay. Due Date: April 16, 2015 Points: 60 Late penalty: 50% per class day Programs are ONLY accepted at the START of the class period on the date due. General Requirement: Create a payroll calculator for a Coffee Shop Specific Requirements: Modularize Program

4 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 You must use the code supplied on the next slides. Boss Module
