You have to change the ListBox.SelectionMode property in order to enable multiple-selection.
The possible values are given by the SelectionMode enum, as follows:

None: No items can be selected
One: Only one item can be selected
MultiSimple: Multiple items can be selected
MultiExtended: Multiple items can be selected, and the user can use the Shift, Ctrl, and arrow keys to make selections

So, you simply need to add the following line to the code you already have:

' Change the selection mode (you could also use MultiExtended here)
lstItemSizes.SelectionMode = SelectionMode.MultiSimple;

' Select any items of your choice
lstItemSizes.SetSelected(1, True)
lstItemSizes.SetSelected(3, True)
lstItemSizes.SetSelected(8, True)

Alternatively, you can set the SelectionMode property at design time, instead of doing it with code.
