Syntax
LB_GETITEMDATA wParam = (WPARAM) index; lParam = 0;
Parameters
index
Index of the item.
Windows 95 and Windows 98: The wParam parameter is limited to 16-bit values. This means list boxes cannot contain more than 32,767 items. Although the number of items is restricted, the total size in bytes of the items in a list box is limited only by available memory.
Return Values
The return value is the 32-bit value associated with the item, or LB_ERR if an error occurs. If the item is in an owner-drawn list box and was created without the LBS_HASSTRINGS style, this 32-bit value was in the lParam parameter of the LB_ADDSTRING or LB_INSERTSTRING message that added the item to the list box. Otherwise, it is the value in the lParam of an LB_SETITEMDATA message.
Remarks
Windows CE does not support owner draw list boxes..
