CSC 230: The Week beginning Sep. 10

Homework

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

• Statement
• String literal
• Keyword
• Increment
• Variable Type
• Cast
• Nesting
• Constant

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)
  

The result is reported in a label. It reports the data (one piece of data per line) used to make the estimate and formats the result as money. If the user changes any of the input data, the result should be cleared out.

  Marx Brothers' Logon

  MarxBrosLogonZip.zip This program allows the Marx Brothers (groucho, chico, harpo and zeppo) to log on using their given names as passwords (julius, leonard, adolph, and herbert, respectively).
  
  • The password TextBox has the password character property set to an asterisk.
  • If the username and password match up to one of the above pairs, then the TextBoxes and Button are disabled and a welcome message in a label and the image of the appropriate Marx brother is displayed.
  • If the username and password don't match one of the above pairs, then a MessageBox pops up saying so.
  • If there are three bad attempts to log on, then the TextBoxes and Button should be disabled to prevent the user from continuing to guess.
  
  
  

  Manet-Monet Quiz

  Using the headstart ManetMonetHeadStartZip.zip and the images ManetMonetImages.zip, make a quiz that tests the user's knowledge of Manet and Monet paintings.
  • The headstart has a Panel which contains a PictureBox, a ComboBox, a Button and a Label. The Panel can be copied and pasted to quickly design the form. (Because of time constraints, I won't insist that you rename the controls for this program.)
  • Change the PictureBox Image properties so that each one is different.
  • Write code for the Buttons, so that the user's choice from the corresponding ComboBox is compared to the correct answer with the result (e.g. "Correct" or "Sorry") displayed in the label.
  • Disable the corresponding ComboBox after the Button is clicked to prevent the user from changing his or her answer.
