The information in this article applies to:
  • Microsoft Win32 Application Programming Interface (API) included with: 

        - Microsoft Windows NT versions 3.5 and 3.51
    - Microsoft Windows 95 version 4.0

To determine whether a multiple selection list box is empty or has no items to select, two messages are required. First, call LB_GETCOUNT to determine whether or not the list box is empty. If the list box is not empty, then use LB_GETCARETINDEX to determine the position of the caret.

If you want a list box to contain selections that remain after the focus goes elsewhere, Microsoft recommends using visible check marks next to the items in the list box. This method provides better visual feedback to the user than a selection bar.
