Use Style to specify whether the list box is a standard list box that displays text strings, or an owner-draw list box that can display graphical images. Owner-draw list boxes let you display items in some nonstandard way. In this case, you must write the code to paint items in the list box.  

In addition, Style controls whether the list box is virtual, which means that items are supplied dynamically using event handlers. By default, Style is lbStandard, meaning that the list box is not virtual and it displays each item as a string.
