Subject: Ignore practice quiz questions NOT COVERED YET...

Hi Visual Basic students,

     When I handed out the practice quiz, I included material and old
quiz questions from several former semesters or summers that we have
NOT covered yet in class.

     When you see a question on the old quiz practice quiz handout
you received on Monday (or Wednesday) of this week, do NOT WORRY about
it.                                                 ------------

     We have NOT yet covered the Mid("Ghostbusters", 6, 3) function
yet, which has 3 arguments.

     We have NOT yet covered FOR NEXT loops yet, which would be
required, along with the Mid() function, to print a word or
phrase vertically on the Form.

     P
     A
     N
     T
     H
     E
     R
     S      <--------- Involves a For Next loop and the string
                                function Mid() to get to each
                                letter of the contents of
                                the variable or textbox.

     Would you like to see the numbers one through ten on your form?

     Try this:
                       For i = 1 to 10
                           Print i
                       Next i

     Would you like to see Panthers printed vertically on your form?

     Try this:
                     For i = 1 to 8
                         Print Mid("Panthers", i, 1)
                     Next i

     Would you like to try another way to Print a phrase on your Form1
     object, where it is whatever phrase you typed into a Textbox?

     Let us say the (Name) property for the TextBox object is txtPhrase.

     txtPhrase.Text might be:  UNI Panthers beat Iowa Hawkeyes!

     For i = 1 to Len(txtPhrase.Text)
        Print Mid(txtPhrase.Text, i, 1)
     Next i

     Be sure to Maximize your running Visual Basic Form, if you have
     such a long phrase as:
                                 UNI Panthers beat Iowa Hawkeyes!
                                 12345678901234567890123456789012
                                          1         2         3
                                                --
     Len(txtPhrase.Text) would return the value 32
                                                --

     Len("Panthers") is 8
     Len("Ghostbusters") would return the value 12, as would
     Len("UNI Panthers").

     We have NOT yet covered the Len() function for Strings, or
                             the Mid() function for Strings, or
                             the For Next loop pattern for repeating
                                 a set of statements 4 or 8 or 12 or 32
                                 or how ever many times we want to repeat
                                 them.

     So save those practice quiz questions for AFTER quiz one.  They
     are probably going to be covered enough to be fair game for
     quiz two on Friday, September 30th.

     Quiz one is on Wednesday, September 21st.
     --------       -------------------------

     Have a great weekend!  If UNI does not beat Iowa, I hope that
     the following variable marginOfVictoryForIowa is the smallest
     for the entire 2005 season for the Iowa-UNI game.    --------
             ------

     IF IowaTeamPoints > opponentTeamPoints THEN
        marginOfVictoryForIowa = IowaTeamPoints - opponentTeamPoints
     END IF

     And that Iowa wins the rest of its games this season after Saturday!
     And both Iowa and Iowa State win their bowl games.
     And that UNI wins the rest of its games this fall too, all of them!
                                                            ---
     Notice the INDENTATION of the assignment statement
                     in the above IF ... THEN statement...

     IF condition that is TRUE or FALSE THEN          TWO WAY SELECTION
         what you want to do if it is TRUE            -----------------
           more statements...
           ...
     ELSE
        what you want to do if it is FALSE
           ...
     END IF
                     How important is INDENTATION???
                                                      VERY IMPORTANT!!!
