The Text property controls the text that appears in the Windows form’s title bar, and on the application’s
button on the Windows taskbar while the application is running. The Name property assigns a name to the
Windows Form object; you use the name to refer to the form in code. The programmer uses the Name
property. The user reads the Text property.
9. A Windows Form object is the form itself. A Windows Form object can be viewed in the designer window
and appears on the screen when the application is run. The form file object is the disk file that contains the
code associated with the Windows Form object.
10. The dot member access operator indicates that the Label class is a member of the Forms namespace, which is
a member of the Windows namespace, which is a member of the System namespace.

The first choice for an access key is the first letter of the caption or identifying label, unless another letter
provides a more meaningful association. If you can’t use the first letter and no other letter provides a more
meaningful association, then use a distinctive consonant in the caption or label. The last choices are a vowel
or number in the caption or label.
10. To give keyboard access to a text box, assign an access key to its identifying label control. Then set the label
control’s TabIndex property to a value that is one number less than the text box’s TabIndex value.

c. The number 500 appears in the xSalesLabel control. The procedure-level sales variable is removed from
memory.
h. The number zero appears because the assignment statement in the xComm5Button’s Click event
procedure multiplies the contents of the sales variable (0) by .05, and then displays the result (0) in the
xCommissionLabel control. When the xComm5Button’s Click event procedure ends, the sales variable
declared in the procedure is removed from memory.
q. When the application ends, the module-level sales variable is removed from memory.
15. (Debugging) See the VB2005\Chap03\laCount Solution files on the Solutions Disk.

The decision regarding the member status is the primary decision. The decision regarding the day of the week
is the secondary decision, because whether it needs to be made depends on the result of the member status
decision.
19. The three errors commonly made when writing selection structures are:
1. Using a logical operator when a nested selection structure is needed
2. Reversing the primary and secondary decisions
3. Using an unnecessary nested selection structure
The “Using an unnecessary nested selection structure” error makes the selection structure inefficient, but not
incorrect.
20. Desk-checking, also called hand-tracing, means that you use sample data to walk through each of the steps in
the algorithm manually, just as though you were the computer.

c Private Sub CalcFee(ByVal base As Integer, ByVal rate As Decimal)
a one value only
d All of the above.
c The name of each argument in the Call statement should be identical to the name of its corresponding
parameter in the procedure header.
a Return stateTax
c Private Sub CalcFee(ByVal base As Integer, ByRef rate As Decimal)
d Both a and c.
c by reference
d To pass a variable by reference in Visual Basic, you include the ByRef keyword before the variable’s
name in the Call statement.

Integer, ByVal p As Integer, ByRef final As Integer)
a Call CalcEndingInventory(begin, sales, purchases, ending)
a True

c grossPay = Calculate(hours, rate)
Unlike a Sub procedure, a Function procedure returns a value when it has completed its task.
When you pass a variable by value, you are passing only the contents of the variable; the receiving procedure
cannot access the variable and cannot change its contents. When you pass a variable by reference, you are
passing the address of the variable in the computer’s internal memory; the receiving procedure can access the
variable and can change its contents. To pass a variable by value, you include the keyword ByVal before the
variable’s name in the procedure header. To pass a variable by reference, you include the keyword ByRef
before the variable’s name in the procedure header.
