Summary:
To obtain the indexes of all the selected items in a multiselection
list box, the LB_GETSELITEMS message should be sent to the list box.
The message LB_GETCURSEL cannot be used for this purpose because it is
designed for use in single-selection list boxes.
Another approach is to send one LB_GETSEL message for every item of
the multiselection list box to get its selection state. If the item is
selected, LB_GETSEL returns a positive number. The indexes can be
built into an array of selected items.
For more information about the LB_GETSELITEMS message, see page 6-38
in the "Windows Software Development Kit Reference Volume 1."
