Windows 95: wParam is 16-bits

LB_SETCARETINDEX

An application sends an LB_SETCARETINDEX message to set the focus rectangle to the item at the specified index in a multiple-selection list box. If the item is not visible, it is scrolled into view.

LB_SETCARETINDEX

wParam = (WPARAM) index; // item index

lParam = MAKELPARAM(fScroll, 0); // flag for scrolling item

Parameters

index

Value of wParam. Specifies the zero-based index of the list box item that is to receive the focus rectangle.

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.

fScroll

Value of lParam. If this value is FALSE, the item is scrolled until it is fully visible; if it is TRUE, the item is scrolled until it is at least partially visible.

Return Values

If an error occurs, the return value is LB_ERR.
