Program Plan Intro

Employee and ProductionWorker Classes

Program plan:

Design the form:

Place a three text boxes control on the form, and change its name and properties to get the employee name, number, and hourly pay rate from the user.

Place a four label boxes control on the form, and change its name and properties.

Place a two radio buttons control on the form, and change its name and properties.

Place a one group box control on the form, and change its name and properties.

Place a command button on the form, and change its name and properties to retrieve the object properties and then display the values into label box.

In code window, write the code:

Program.cs:

Include the required libraries.

Define the namespace “Program11_1”.

Define a class “Program”.

Define a constructor for the class.

Define required functions to run “Form1”.

Form1.cs:

Include the required libraries.

Define namespace “Program11_1”.

Define a class “Form1”.

Create an object for ProductionWorker derived class.

In btnDisplay() method,

Assign the text boxes inputs to fields of base class and derived class using “pdWorker” object of “ProductionWorker” derived class.

Display the retrieved fields into label box.

In radioButton1_Click() method,

Check whether the first radio button is selected. If yes, set the shift number as “1”.

In radioButton2_Click() method,

Check whether the second radio button is selected. If yes, set the shift number as “2”.

Close the application.

Employee.cs:

Include the required libraries.

Define namespace “Program11_1”.

Define a base class “Employee”.

Declare the required fields.

Define the parameterless constructor to initialize the required fields.

Define Name and Number property to use get and set methods.

ProductionWorker.cs:

Include the required libraries.

Define namespace “Program11_1”.

Define a derived class “ProductionWorker” which is derived from base class “Employee”.

Declare the required fields.

Define the parameterless constructor to initialize the required fields.

Define Shift Number and hourly rate property to use get and set methods.

Form Design:

View the Form Design in IDE.

Set the Form Control properties in Properties window as follows:

Object	Property	Setting
Form1	Text	Program11_1
label1	Text	Employee Name:
label2	Text	Employee Number:
label3	Text	Hourly Pay Rate: $
textBox1	Text	(Empty)
textBox2	Text	(Empty)
textBox3	Text	(Empty)
lblResult	Text	(Empty)
groupBox1	Text	Shift Number:
radioButton1	Text	day (1)
radioButton2	Text	night (2)
btnDisplay	Text	Display
