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 Script Editor of a form. To run the code you need to open the form so the Open event will activate. Make sure that the form contains a ListBox named ListBox1 and a CommandButton named CommandButton1.

Dim Listbox1
Dim MyArray(6, 3)

Sub Item_Open
  Dim i
  Set Listbox1 = Item.GetInspector.ModifiedFormPages("P.2").Listbox1
  
  Listbox1.ColumnCount = 3
  For i = 0 to 5
    MyArray(i, 0) = i
    MyArray(i, 1) = Rnd
    MyArray(i, 2) = Rnd
  Next

  Listbox1.List() = MyArray
End Sub

Sub CommandButton1_Click
  Dim i
  Dim Temp
  
  For i = 0 to 5
    Temp = Listbox1.List(i, 0)
    Listbox1.List(i, 0) = Listbox1.List(i, 2)
    Listbox1.List(i, 2) = Temp
  Next
End Sub
