MIS 310 Central Connecticut State University Distance Calculator App Worksheet

Objectives for this assignment:

• Ability to get inputs from the textboxes; handle exceptions (using try…catch and parse OR tryparse); handle input validation.
• Ability to use If and/or Switch statements to check conditions (you can choose any form of selection statements in the applications)
• Ability to perform operations to obtain outputs from the given inputs
• Ability to add items to the listbox(es)
• Ability to use looping to obtain desired outputs
• Ability to format outputs
• Ability to zip the projects for project submission

Work on the following programming problems found at the end of the chapter (Note: I have changed most of the requirements for the programming exercises)

• • 1 – Distance Calculator
  • 3 – Temperature Converter
  • 7 – Calories Activities

The sample outputs are found in the pdf file.

Download the zipped file, Assignment 6. Extract the zipped file to Assignment 6. Rename the Assignment 6 folder to “Your Name Assignment 6”. This folder should contain the three project folders that you will be working on.

Note: I am no longer testing your ability to change properties. All the properties on the form and controls have been changed. I have also included the constants to be used in the applications.

For each application, provide the appropriate coding for each button as follows:

• Distance Calculator (points allocated: 18, 15, 4, 3)
• button Calculate
  • Declare appropriate input and output variables. (Since they are all numbers, you should use double.)
  • Check that a speed is selected from the comboxbox. If no speed is selected, provide an error message, set the focus on the combobox and do NOT continue with the processing.
  • Check that the data entered in the textbox is a number. If error, display an error message, select the data in the textbox and set the focus on the textbox and do NOT continue with the processing.
  • Check that the number is greater than 0. If error, display an error message, select the data in the textbox and set the focus on the textbox. Do not continue with the processing.
  • Calculate distance traveled as follows: Distance = Speed * Hour
  • Add the following to listbox Output: “Miles covered in x hours at y MPH: “
  • Add the following to listbox Distance: z (distance calculated displayed to 1 decimal place)
  • Set the combobox to no item selected and set focus to the combobox
  • Clear the textbox

• button Get Total Distance
  • Check that there is data in the listbox Distance
    • If the listbox is empty, display an error message that there is nothing to add and set focus on the combobox
    • If the listbox is not empty, use looping to add all the items in the listbox. Display the total distance in a message box with the following information “Total Distance Traveled is zzz Miles” (display total distance to 1 decimal place.

• button Reset
  • Set the combobox to nothing selected
  • Clear the input textbox
  • Clear the output listboxes
  • Set the focus at the combobox

• button Exit
  • Use a messagebox to confirm that the user wants to exit the application

• Temperature Converter (points allocated: 14, 14, 5, 2)
• button Convert to Fahrenheit
  • Declare starting and ending °F as integers; declare output °C as double.
  • Check that the starting and ending °F are integers and that ending °F is bigger than starting °F; if error, provide an error message and allow the user to re-enter the data setting the focus on the starting °F. Do NOT continue with the processing.
  • For the valid data entered, display the converted °C in the listbox in steps of 1°F using the formula C = (F – 32)*5/9; output C should be displayed to 1 decimal place.

• button Convert to Celsius
  • Declare starting and ending °C as integers; declare output °F as double.
  • Check that the starting and ending °C are integers and that ending °C is bigger than starting °C; if error, provide an error message and allow the user to re-enter the data setting the focus on the starting °C. Do NOT continue with the processing.
  • For the valid data entered, display the converted °F in the listbox in steps of 1°F using the formula F = 9/5C + 32; output C should be displayed to 1 decimal place.

• button Reset
  • Clear the input textbox
  • Clear the output listboxes
  • Add the headings to the two listboxes
  • Set the focus at the starting °F textbox

• button Exit
  • Use a messagebox to confirm that the user wants to exit the application

• Calories Activities (points allocated: 18, 15, 4, 3)
• button Enter
  • Declare input minutes entered as double and output calories as double.
  • Check that the data entered in the textbox is a number. If error, display an error message, select the data in the textbox and set the focus on the textbox and do NOT continue with the processing.
  • Check that the number is greater than 0. If error, display an error message, select the data in the textbox and set the focus on the textbox. Do not continue with the processing.
  • Calculate calories burned based on the activity selected as follows: Calories burned = Minutes entered * Given Constant for Activity/30
  • Add the following to listbox Activity: Text of the Activity Selected
  • Add the following to listbox Minutes: Minutes entered (display to 1 decimal place)
  • Add the following to listbox Calories Burned; Calculated Calories burned (display to 1 decimal place)
  • Set the focus on the first radiobutton
  • Clear the textbox
  • EXTRA CREDIT: Add the activity, minutes and calories burned to a text file which has 3 headings as shown in the listboxes. The text file has to be created in the bin/debug folder (8 points).

• button Summary
  • Check that there is at least one data in the listbox minutes (NOTE: the heading is not data so you will need to check that count is >2)
    • If there is no valid data in the listbox, display an error message that there is nothing to summarize and set the focus on the first radiobutton
    • If valid data exists, use looping to add all the items in listbox minutes and listbox calories. Display the summary information in a message box as follows:
      • Total Activity Minutes: xxx (displayed to 1 decimal place)
      • Total Calories Burned: yyy (displayed to 1 decimal place)

• button Reset
  • Set the focus to the first radiobutton
  • Clear the input textbox
  • Clear the output listboxes
  • Add headings to the 3 listboxes

• button Exit
  • Use a messagebox to confirm that the user wants to exit the applicationObjectives for this assignment:
