CSC 230: The Week beginning Sept. 13

We should have a test next week.

• Homework:
  
  

  Provide a brief definition of the following terms (in the interface programming context):

  • Concatenation
  • Double
  • Nested If
  • String
  • Try-Catch
  • Type Conversion
  • Variable declaration
  If you use a source (book or web site), cite your source. (The sites http://whatis.techtarget.com/ and http://www.webopedia.com/ are decent sources for technical definitions.)
  
  
  

  You must have a comment with your name as well as meaningful control names.

  Design a form like that above

  • It has a checkbox that allows the user to indicate whether or not the house has central air.
  • It has a combobox that allows the user to select the season (Spring, Summer, Fall or Winter). When the user selects a season change the color of the label (spring: light green, summer: light yellow, fall: wheat, winter: white).
  • It has a second combobox that allows the user to select the style of home (Single, Duplex or Row).
  • It has a button that estimates the monthly electric bill based on the information entered above. (If a season or style was not selected, a messagebox arises and the offending combobox is given the focus.)
  • The basic estimates are as follows:

     	Single
    		Fall, Spring:	$50.00
    		Winter:	$250.00
    		Summer:	$50.00 (without central air), $200.00 (with)
    	Duplex
    		Fall, Spring: 	$40.00
    		Winter:	$200.00
    		Summer:	$40.00 (without central air), $150.00 (with)
    	Row
    		Fall, Spring:	$35.00
    		Winter:	$175.00
    		Summer:	$35.00 (without central air), $125.00 (with)
    

  
  
  Due: Sept. 20
  
  
• Monday:
  
  DatePicker_2.zipFinished date picking program from last Friday
  Piano.zip (a bit of fun)
  Movies.zip
  
  
• Wednesday (morning):
  
  Movies_2.zip Finished movie program from Monday.
  Octet.zip (Decimal to Binary converter, shows one methods handling many events)
  Not done yet.
  
  
• Wednesday (afternoon):
  
  Part 1. Location program
  Write a program like MyLocation.exe It should have
  • Two ComboBoxes -- one for days and one for hours.
  • A Button that when clicked puts your expected location (the variable mentioned below) into a Label
  • A String variable that is initially set to some default value. My was "Your guess is as good as mine."
  • Nested Select-Case statements that change the variable above to values giving your location at particular days and times.
  Also when the user changes the selection in either the ComboBox, clear out the Text in the Label.
  
  Old Navy Tees
  Write a program like OldNavyTees.zip (this zip file should contain an exe and a folder named Images containing .jpg's and .gif's). When a user places the mouse over a color swatch the image of the tee shirt switches to that color, etc.
  
  • Remember to import the System.IO
  • Set a String variable for the "path" of the folder holding the program's exe.
  • Have one big PictureBox for the T-shirt images
  • Have seven little PictureBoxes for the color swatches
  • Place the gif images into the color swatches
  • Declare a String variable for the "default" T-shirt image
  • Place the default t-shirt image in the large PictureBox
  • Make MouseEnter event-handling methods for the little PictureBoxes that change the image to the shirt image with a color that matches the little PictureBox
  • Have a MouseLeave event-handling method for each little PictureBox that reverts the t-shirt image back to the default image
  • Have a Click event-handling metod for each little PictureBox that changes the default image variable to that picture of the t-shirt that is the same color as the little PictureBox
  
  
  
• Friday:
  
  OldNavyTshirts.zip (as requested a somewhat more efficient approach to Wednesday's Old Navy part of the lab)
