ListBox Control, List Property Example

The following example swaps columns of a multicolumn ListBox. The sample uses the List property in two ways:

1. To access and exchange individual values in the ListBox. In this usage, List has subscripts to designate the row and column of a specified value.
   
   
2. To initially load the ListBox with values from an array. In this usage, List has no subscripts.

To use this example, copy this sample code to the Declarations portion of a form. Make sure that the form contains a ListBox named ListBox1 and a CommandButton named CommandButton1.

Dim MyArray(6, 3)           
'Array containing column values for ListBox.

Private Sub UserForm_Initialize()
    Dim i As Single

    ListBox1.ColumnCount = 3        
'This list box contains 3 data columns

    'Load integer values MyArray
    For i = 0 To 5
        MyArray(i, 0) = i
        MyArray(i, 1) = Rnd
        MyArray(i, 2) = Rnd
    Next i

    'Load ListBox1
    ListBox1.List() = MyArray

End Sub

Private Sub CommandButton1_Click()
' Exchange contents of columns 1 and 3

    Dim i As Single
    Dim Temp As Single

    For i = 0 To 5
        Temp = ListBox1.List(i, 0)
        ListBox1.List(i, 0) = ListBox1.List(i, 2)
        ListBox1.List(i, 2) = Temp
    Next i
End Sub
