<<Lesson 22>> [Contents] <<Lesson 24>>
We have learned how to work with check boxes, option buttons and text boxes in Excel VBA in the previous lesson. We shall continue to learn how to manipulate other Excel VBA controls in this lesson.
23.1 The ListBox
The function of the ListBox is to present a list of items where the user can click and select the items from the list. To add items to the list, we can use the AddItem method.
To clear all the items in the List Box, you can use the Clear method. The usage of Additem method and the Clear method is illustrated in Example 19.1 and The output is as shown in Figure 23.1
Example 23.1
Private Sub CommandButton1_Click()
For x = 1 To 10
ListBox1.AddItem “Apple”
Next
End Sub
Private Sub CommandButton2_Click()
For x = 1 To 10
ListBox1.Clear
Next
End Sub

23.2 ComboBox
The function of the ComboBox is also to present a list of items where the user can click and select the items from the list. However, the user needs to click on the small arrowhead on the right of the combo box to see the items which are presented in a drop-down list. In order to add items to the list, you can also use the AddItem method. The usage involving ComboBox is as shown in Example 19.2 and the output is as shown in Figure 19.2.
Example 23.2
Private Sub CommandButton1_Click()
ComboBox1.Text = “Apple”
For x = 1 To 10
ComboBox1.AddItem “Apple”
Next
End Sub
Private Sub CommandButton2_Click()
ComboBox1.Clear
End Sub

23.3 Toggle Button
Toggle button lets the user switches from one action to another alternatively. When the Toggle button is being depressed, the value is true and when it is not depressed, the value is false. By using the If and Else code structure, we can thus switch from one activity to another by pressing the toggle button repeatedly.
Example 23.3
In this example, the user can toggle between apple and orange as well as font colors.
Private Sub ToggleButton1_Click ()
If ToggleButton1.Value = True Then
Cells (1, 1) = “Apple”
Cells (1, 1).Font.Color = vbRed
Else
Cells (1, 1) = “Orange”
Cells (1, 1).Font.Color = vbBlue
End If
End Sub
