Program Plan Intro

Distance converter

Program plan:

Design the form:

  • • Place a one text boxes control on the form, and change its name and properties to get the distance from the user.
  • • Place a three label boxes control on the form, and change its name and properties.
  • • Place a two group boxes control on the form, and change its name and properties.
  • • Place a two list boxes control on the form, and change its name and properties to list of items.
  • • Place a command button on the form, and change its name and properties to convert distance and then display it.
  • • Place a command button on the form, and change its name and properties to end the application.

In code window, write the code:

Program.cs:

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

Form1.cs:

  • • Include the required libraries.
  • • Define namespace “DistanceConverter”.
    • ○ Define a class “Form1”.
    • ○ In btnConvert() method,
      • ■ Declare the required variables.
      • ■ Check whether selected index for From list and To list is not equal to “-1”. If yes, display the result.
      • ■ Otherwise, check whether From list is equal to “Yards” and To list is equal to “Feet”. If yes, calculate the distance in feet and display the result.
      • ■ Otherwise, check whether From list is equal to “Feet” and To list is equal to “Yards”. If yes, calculate the distance in yards and display the result.
      • ■ Otherwise, check whether From list is equal to “Yards” and To list is equal to “Inches”. If yes, calculate the distance in inches and display the result.
      • ■ Otherwise, check whether From list is equal to “Inches” and To list is equal to “Yards”. If yes, calculate the distance in yards and display the result.
      • ■ Otherwise, check whether From list is equal to “Feet” and To list is equal to “Inches”. If yes, calculate the distance in inches and display the result.
      • ■ Otherwise, check whether From list is equal to “Inches” and To list is equal to “Feet”. If yes, calculate the distance in feet and display the result.
    • ○ In btnClose() method,
      • ■ Close the application.
