use the "check" parameter for the list box in your dialog layout.
This will give you your list, with a check box beside each item.
Note that these check boxes are a simple on/off format, and changes when you select the item in the list.
You will still have to change the sclick event so that it references the clicked item in the list.
See /help /did for more reading.
