Gets the 32-bit data value associated with an item.

An application sends an LVM_GETITEMADDDATA message to a listview to get the 32-bit data value stored for the item with index of <em>wParam</em>; By default this is zero. An application must set the item data value by sending an LVM_SETITEMADDDATA message to the listview for this value to have meaning.<p>
