ListBox control, List property example

  • Artikkeli

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

  • 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.

  • 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
