First you need to set the ListBox.SelectionMode property to ether MultiSimple or MultiExtended depending on how you want the selection process to work in the ListBox. Then you can select multiple items in the ListBox with the Mouse.

If you want to set the selected items in code, then you can do it by adding the Indexes of the items you want selected to the ListBox.SelectedIndices collection as shown in the example below.

Expand|Select|Wrap|Line Numbers
  1. Public Class Form1
  2.  
  3.     Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
  4.         ListBox1.SelectionMode = SelectionMode.MultiSimple
  5.     End Sub
  6.  
  7.     Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
  8.         ListBox1.SelectedIndices.Add(1)
  9.         ListBox1.SelectedIndices.Add(3)
  10.         ListBox1.SelectedIndices.Add(6)
  11.     End Sub
  12. End Class
  13.  
You could also do it by adding the Items you want selected to the SelectedItems collection.
