Control Structure

In this lab assignment, you will create a “TimeEntry” windows form application, user will input work hours for each day in a week (5 days) repeatedly, the program will record the user’s time entries, calculate the payment and display on the form.  Please follow the following steps to complete this assignment.

•         Create a new Windows Form Application “TimeEntry”.

•         Design and define the GUI similar to the following form:

•         User will enter time (hours) in the textbox, suppose user always input valid integer hours.

•         Set “Submit time” button as the default button for the form, this button will be pressed when the user presses the Enter key.

•         Add a ListBox to record and display the time entries for 5 days, after user enter hours for one day, it will be shown in the ListBox immediately.

•         The “Get payment” button is disabled when program starts to run.

•         After user enters hours for 5 days, the TextBox and “Submit time” button are disabled; the “Get payment” button is enabled.

•         Create and define 3 event handler methods to handle the button_click events for 3 buttons.

•         When click “Submit time” button -----

•         If the TextBox is not empty and user entered less than 5 time entries, the hours entered in the TextBox will be read and added in the ListBox.

•         If user has already entered 5 time entries, then disable the “Submit time” button and hours TextBox, enable “Get Payment” button.

•         When click “Get payment” button -----

•         Use a counter controlled repetition statement to read time entries repeatedly from ListBox for calculation.

•         Calculate the total hours

•         Calculate user’s payment following the rules below

•         If the total hours is less than or equal to 40, then calculate payments, otherwise, display an error message to the user.

•         If total hours is between 0 and 20 hours, the hourly wage is $10.00

•         If total hours is between 21 and 30 hours, the hourly wage is $12.00

•         If total hours is between 31 and 40 hours, the hourly wage is $15.00

•         Display user’s payment as the Text property of the result Label.

•         You may use this code to display the payment in a currency format.

PayLabel.Text = String.Format("{0:C2}", Payment)

•         When click “Clear time” button ----

•         The TextBox, ListBox and result label will be cleared

•         The form should be converted to the initial format.
