Subject: Making a target and coloring the stairstep rectangles...


Hello Visual Basic students,

    http://www.cns.uni.edu/~jacobson/030VB.NET/BullsEyeSteps.gif

    Try to create the bull's eye target, if you can.


         Dim brush As SolidBrush

         draw = Me.CreateGraphics
         brush = New SolidBrush(Color.Purple)

    Notice I changed to SolidBrush for the variable brush...
                        ----------

    That allowed me to do this:

        brush.Color = Color.FromArgb(Rnd() * 255, Rnd() * 255, Rnd() * 255)

    and get RANDOM colors using the Color.FromArgb() method from
                                the Color
                                          class.

        For i As Integer = 300 To 50 Step -50
             rect.Width = i
             rect.Height = i

             YOU TRY TO FIGURE OUT THE REST of the For Next loop body
                        set of actions that goes here....

        Next i

    I will add to the following midterm study guide some additional topics
    that we have covered since then.  However, this study guide is a good
    place to begin reviewing for the final exam.

    17.  Know how to read a file that contains numbers separated by
         spaces or semicolons on each line.

         Display the name of each student followed by
                       the sum of the 3 scores, i.e. their total points:

         (Display the name and total points in a Label named lblScores)

         Example data file (named scores.txt):

         Frodo Baggins;95;83;71      <--------- What is GIVEN?
         Cinderella;100;88;96
         Bilbo Baggins;59;72;81                 The INPUT or data
         Jimi Hendrix;75;77;68                      is a file named:
         Joan Osbourne;91;81;71
         Wes Montgomery;100;97;98                    scores.txt on
         Carlos Santana;94;81;99                     C:\VB\scores.txt path.
                                                     ----------------

         Here is what the output shown in lblResults would look like
              for the above data:         ----------

         Frodo Baggins  249
         Cinderella  284
         Bilbo Baggins  212
         Jimi Hendrix  220
         Joan Osbourne  243
         Wes Montgomery  295
         Carlos Santana  284
