  • OR you can give them the same name (VB will ask u
    if you want to create a control array answer
    Yes)

Option Buttons
  • It can be used in programming in two ways
  • 1. Use the Click event if you want to take an
    action when users select an option. (Control
    Array) Happens Immediately
  • Private Sub optWash_Click(Index As Integer)
  • Select Case Index
  • Case 0
  • MsgBox You selected Normal
  • Case 1
  • MsgBox You selected Heavy Duty
  • Case 2
  • MsgBox You selected Pots and Pans
  • End Select
  • End Sub

Option Buttons
  • 2. use an if statement to check their state (no
    control array) Do not Happen Immediately
  • Private Sub cmdStartWash_Click()
  • If optNormal True Then
  • MsgBox You selected Normal
  • Elseif optHeavy True Then
  • MsgBox You selected Heavy Duty
  • Else
  • MsgBox You selected Pots and Pans
  • End If
  • End Sub

14
Option Buttons
  • To have multiple option buttons on a form
    selected at the same time separate the option
    buttons into groups by using container controls
    (frame).

15
Frames
  • A type of control called a container.
  • Containers are controls in which you can draw
    other controls.
  • After you draw a Frame control, you are ready to
    start placing other controls in it. You can place
    any controls you like in the frame (or any other
    container). You can even place containers within
    containers.
  • The only way to move a control from other parts
    of the form into the frame is to cut and paste
