– MESSAGE BOX
Chapter Five
When you add items to a ComboBox List VB.Net
assigns each one an unique index number.
The first item is assigned an index of 0; the second item
gets an index of 1; and so on.
– For example: Index Numbers for Auto Loan Program
A -- Excellent Credit Rating
B – Good Credit Rating
=0
=1
etc ….
SelectedIndex is the property that keeps track of what
index number is currently being accessed.
When no item is selected, the SelectedIndex property
is set to -1. The following line of code would clear the
ComboBox:
If…Then…Else Structure
Select Case Structure
Chapter Five
Used to execute one statement or another
conditionally.
– IF THEN STATEMENTS
– The condition follows the keyword IF
– A condition is made up of two expressions and a
relational (comparison) operator.
Equal =
Less than or equal to <=
Less than < Greater than or equal to >=
Greater than >
Not equal to <>
When you have an if…then within an if then!
– NESTED IF THEN STATEMENTS

Coding a Select Case Statement
Chapter Five
Used to combine two or more conditions in
an expression. All parts must be true for
the True section of code to trigger!
– AND LOGICAL OPERATOR
For example:
If strGender = “M” And intAge < 12 Then
MessageBox.Show(“Boys Little League”)
End if
Chapter Five
The process of adding strings together. It is
performed with the ampersand [ &]
character.
– CONCATENATION
The plus sign (+) can be used instead of
the (&) operator. Often times programmers
avoid the + sign since it is used in
mathematical problems as well.

ListView Control.
ANSWER QUESTION 2:
– VIEW PROPERTY
Switch to __________ if you want multiple
columns to show up in the listview control.
ANSWER QUESTION 3:
– DETAILS
QUESTION 4:
Rather than having to code changes for
the width, height, and location of every
control, VB.NET allows you to set a fixed
location, or _____________, for controls
to specified sides of a form.
ANSWER
– ANCHOR
QUESTIONS 5 & 6:
Most .NET applications contain more than
one form.
ANSWER:
– TRUE
If the first form is used to launch the
second form it is sometimes referred to as
the __________.
ANSWER
– PARENT
QUESTIONS 7 & 8:
The ________________________ is used
in applications to allow a user to specify
one of two conditions, such as on or off,
yes or no, or true or false.
ANSWER
– CHECKBOX CONTROL
Determines whether the box is checked or
not. It’s either True or False.
ANSWER
– CHECKED PROPERTY
QUESTION 9:
Well, as is the case with all forms, the
Today’s Sales Entry Form is a
____________, which means that an
instance of the class must be declared
before it can be used. This can be done
with an _________________________.
ANSWER
– CLASS
– OBJECT VARIABLE
QUESTIONS 10 & 11:
The _______________________ determines whether the
variable contains a complete instance of the object.
ANSWER
– NEW KEYWORD
If the New keyword is not used, then the variable is
declared for future use but no memory is set aside for
the contents of the object.
If the New Keyword is used, the object is said to be
_____________________ and memory is set aside for a
complete copy of the object. You can’t use a new form
until this is done.
Answer
– INSTANTIATED
QUESTIONS 12 & 13
If the __________________ is used in a form’s code to
open another form, then both forms still can receive
focus and be accessed by the user.
– This is called a ____________________ – meaning that
the user can flip back and forth between the forms.
ANSWERS
– Show() Method, modeless
The ______________________ is used to open a
________________ form.
– This means that the user must complete the action on the modal
form before they will be allowed to continue work on other forms.
ANSWERS
– Show Dialog(), modal
QUESTION 14

______________.
ANSWER
– LOOPING OR REPETITION
QUESTION 15:
This statement repeatedly executes a series of statements
in the loop as long as the condition is true.
ANSWER:

Do While intCount <=20
intCount = intCount +1
Loop
Do
intCount = intCount +1
Loop While intCount <=20
QUESTION 16:
This statement loops until the condition becomes
true.
ANSWER:
