Program Plan Intro

Magic Dates Revisited

Program plan:

Design the form:

• Place one text boxes control on the form and change its name and properties to get the date, month and year from the user.
• Place four label boxes control on the form and change its name and properties.
• Place command button on the form and change its name and properties to check and display the magic date.

In code window, write the code:

Program.cs:

• Include the required libraries.
• Define the namespace “MagicDate”.
  • Define a class “Program”.
    • Define a constructor for the class.
    • Define required functions to run “Form1”.

Form1.cs:

• Include the required libraries.
• Define namespace “MagicDate”.
  • Define a class “Form1”.
  • In btnCheck() method,
    • Declare the required variables and initialize with textbox inputs.
    • Check whether the multiple of month and date is equal to year. If yes,
      • Display the magic message.
      • Otherwise, display the error message.
    • Close the application.

View the Form Design in IDE.

Set the Form Control properties in Properties window as follows:
