Thank you. It works. Here is another question related to
this one. I have two list boxes on the same form. I
select two items on the list box1, the selected items get
highlight color, I also need to select three items on list
boxe2. When the focus move to the second list box, the
highlight color for the selected items disappear in the
list box1. What should I do to keep the selected items
showing in list box1 when I click on another control?

Use a list box instead of a combo box and on the Advanced
Properties dialog for the control, set its MultiSelect
property to 1 - Multi.
