CSC 230: The Week beginning Nov. 5

Homework

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

• Local variable
• Global variable
• Constant variable
• Static variable

AddressBookZip.zip

• Make a UserControl consisting of two TextBoxes.
• On the Form make a panel with a number of your UserControls.
• Read the address file (names and phones numbers actually) and display the first few in the TextBoxes.
• Have Forward and Back buttons that allow the user to move through the list. (It's possible that at the end not all of the UserControls will be filled with data.)
• Disable Back when the user is at the beginning; disable Forward when the user is at the end.
• (If you are looking for a bit more of a challenge, allow the user to edit an entry. The edit should be written to the text file, so that it appears the next time the program is run.)
• (Another thing to try is to allow the user to add an entry.)

Due: Nov. 12

• Monday

  
  IMAGESLETTER.zip
  SignLanguageZip.zip (convert a string to an array of characters)
  
  

• Wednesday

  
  WriteRepZip.zip (in-class lab, exe and text file)
  
  
  
  
  
  
  • The program reads a file from http://clerk.house.gov/member_info/ASCIImemberlabels_110.txt (with the first and last rows eliminated) and instantiates and initializes arrays for Prefix, FirstName, MiddleName, LastName, Suffix, Address, City, State, Zip
  • (I also made one more array LFName which was the lastname followed by a comma and a space and the first name, which is what I put in the listbox of the left.)
  • When the user clicks the button between the lists, the selected item from the left list is added to the right list. (Pop up a MessageBox if the user doesn't select someone of the left.)
  • When the user clicks the Save button. Loop through the items in the right listbox.
  • Find the index that corresponds to each representative in the right listbox. Basically you are finding the position in the left listbox of each item in the right listbox. (This is where I used that extra array I made.)
  • Use the arrays and concatenation to make the letters with the saluation, the body, and the signing. Today.ToLongDateString was used to get the date.
  • Instantiate the StreamWriter in the loop. Use the LastName followed by the FirstName followed by .txt for the name of the file.
  • Pop up a MessageBox that says where the files have been saved.

  We will also work on the following labs and any other old unfinished labs this Friday.

  Word Jumble

  WordJumbleZip.zip

  • Read in an array of words from one of the files provided.
  • Shuffle them so that they are in a random order.
  • When the user clicks Next, break the "next" word into an array of characters, shuffle those characters and display them in a label. Also disable Next and enable Check. Also clear out any previous guess made by the user.
  • When the user clicks Check, determine if the user's guess in the TextBox is correct. (Your check should be case-insensitive.) If the user's guess is correct, display a MessageBox saying so. If it is not, display the correct word. Also disable Check, enable Next.

  State-Capital Quiz Revisited

  NewStateCapitalQuizZip.zip

  • Make a UserControl consisting of a Label and a TextBox.
  • Have a Label, a NumericUpDown and an OK Button and a Panel beneath them.
  • Place a Grade Button and Label for displaying the results below the Panel.
  • When the user clicks the OK button, get the number from the NumericUpDown control and add that many of your UserControls to the Panel. (Clear any previous UserControls from the Panel.)
  • Place them in a vertical column. Add code that changes the size of the Panel so it can accommodate the UserControls. Re-locate the Grade Button and Display Label so that it is beneath the Panel. Change the height of the Form so that it can accommodate all of the rest.
  • Shuffle the States and Capitals (in the same loop keeping the state and its capital together). Place the name of the first few states into the Label portion of the UserControl.
  • Clear out any old result in the Display Label. Enable Grade and disable OK.
  • When the user clicks Grade, loop over the UserControls comparing the user's guess in the TextBox part of the UserControl to the correct Capital.
  • Add up the number of correct and display the result correct in a form X out Y as well as in percentage format.
  • Make the TextBoxes ReadOnly. Make the font color of any incorrect entry red.
  • Enable OK and disable Grade.
