LB_SETITEMDATA
An application sends an LB_SETITEMDATA message to set a 32-bit value
associated with the specified item in a list box.
LB_SETITEMDATA
wParam = (WPARAM) index; // item index
lParam = (LPARAM) dwData; // value to associate with item
Parameters
index
Value of wParam. Specifies the zero-based index of the item.
Windows 95: 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 listbox is limited only by available memory.
dwData
Value of lParam. Specifies the 32-bit value to be associated with the item.
Return Values
If an error occurs, the return value is LB_ERR.
Remarks
If the item is in an owner-drawn list box created without the LBS_HASSTRINGS
style, this message replaces the 32-bit value contained in the lParam parameter of the LB_ADDSTRING or LB_INSERTSTRING message that added the item
to the list box.
