LB_GETSELITEMS
An application sends an LB_GETSELITEMS message to fill a buffer with an array
of integers that specify the item numbers of selected items in a
multiple-selection list box.
LB_GETSELITEMS
wParam = (WPARAM) cItems; // maximum number of items
lParam = (LPARAM) (LPINT) lpnItems; // address of buffer
Parameters
cItems
Value of wParam. Specifies the maximum number of selected items whose item numbers are to be
placed in the buffer.
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.
lpnItems
Value of lParam. Points to a buffer large enough for the number of integers specified by the cItems parameter.
Return Values
The return value is the number of items placed in the buffer. If the list box
is a single-selection list box, the return value is LB_ERR.
