On a party boat sailing out of Captree, four fishers (Irene, Julio, Kate and Lenny) caught prize fish. Each of
the four caught a different type of fish (bluefish, mako, pollack or weakfish), and each lives in a different
Long Island town (Amityville, Bay Shore, Copiague or Deer Park). Can you find the kind of prize fish
each of the four fishers caught and the hometown of each?
1. The Amityville fisher didn't catch the pollack or weakfish.
2. Julio didn't catch the bluefish or mako.
3. Lenny isn't from Copiague.
4. Irene either is from Bay Shore or caught the pollack or both.
5. Kate and the fisher from Bay Shore caught, in some order, the prize pollack and mako.
6. Three of the four people are the fisher from Amityville, the one who caught the bluefish and Irene.

Every kind of visual basic control has a prefix that should start
its name.
Forms (a window) should start with frm
Labels should start with lbl
And buttons should start with btn
This way you instantly know what kind of control you are
working with
To manipulate a control you need to know its name.
The name is different than the appearance.
We access or change properties of a control named susan by
using susan.property
HW
Write a visual basic window program that does something
interesting with labels and buttons
