In windows programming, there are ListBox (or ComboBox) control messages that are 'LB_SETITEMDATA' & 'LB_GETITEMDATA'.
These messages should be very useful while adding and retrieving the strings in ListBox control window. But I only found using 'SendMessage' to add and get strings from the ListBox control window in the books. I am not very clear the usages of these messages.
Could someone show me an example of how to use the ListBox control window messages 'LB_SETITEMDATA' & 'LB_GETITEMDATA' in windows programming?
