1.  If B = 3 Then
       B = 2
       End If
    *You must include the "Then" word.

2.  Because the current value of the MyVariable is equal to 3, 
    the statements under Case 3 are executed.

the menu item completely disappears.  You may have a need to completely
hide a menu item or a menu in some programs.

2.  A menu control array is created during design time by setting the
Index property of a meny item to 0.  This menu item becomes element
number 0 of the array.  During run-time, the program may add items
to the menyu by adding more elements to the array.  

3.  A shortcut key enables you to execute a meny item by pressing
a combination of keys on the keyboard.  You assign a shortcut key to 
menu item during design time by setting the Shortcut property of the 
menu tiem to the desired key combination (e.g. Ctrl+C, Ctrl+A, etc.)

4.  A check mark is used to mark menu items.  To place a check mark
next to a menu item during runtime, set the Checked property of the 
item to True.  To remove a check mark, set the Checked property of the
item to False.

5.  A separator bar is a horizontal line that is used to separate 
menu items.  The Caption property of a separator bar is the hyphen

Quiz 6 - Dialog Boxes

1.  The MsgBox statement and MsgBox() function take the same parameters
and display the same dialog boxes.  The only difference between them
is that the MsgBox() function returns a value that represents the 
button that the user selected in the dialog box.  The MsgBox state-
ment does not return any value.

2.  This statement displays a dialog box with the title ERROR, the 
message "File is missing!" and an OK button.

3.  This code displays a message box with the title DEMO, the question
message "Exit the program?" and Yes and No buttons.  If the user 
clicks the Yes button of the dialog box, the MsgBox() function returns
the value ID_YES, in which case the condition of the If statement is 
satisfied and the program terminates with the End statement

4.  This code users the InputBox() function to display a dialog box that
prompts the user to enter a name.  The returned value of the InputBox
function is assigned to the variable UserName. If the user enters a 
name and does not press the Cancel button, the variable UserName is not
null, in which case the condition of the If statement If Username <>"" 
is satisfied and the user is prompted with a Hello message that 
displays the user's name.

5.  This statement users the Show method to display the frmMyDialog
dialog box as modal.

6.  This statement uses the Hide method to hide the frmMyDialog dialog
box from view.  After executing this statement, the frmMyDialog dialog
box disappears.  Typically, this statement is used in the code of the
terminating buttons of the dialog box.  For example, after the user
responds to the dialog box by pressing the OK (or Cancel) button, use
the Hide method to hide the dialog box from view.

7.  This statement displays the Save As common dialog box.

3.  When the AutoSize property is set to True, the object sizes 
itself tot he exact dimensions of the picture file.

4.  The AutoSize property is supported by a picture control and by
a label control.  When this property is set to True, Visual Basic
adjusts the size of the control so that the control fits its content.

The Stretch property is supported by an image control.  When this 
property is set to True, the size of the picture is stretched to fit
the size of the image control.
