Syntax
LB_GETSELITEMS wParam = (WPARAM) cItems;
lParam = (LPARAM)(LPINT) lpnItems;
Parameters
cItems
Specifies the maximum number of selected items whose item numbers are to be placed in the buffer.
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.
lpnItems
Long pointer to a buffer large enough for the number of integers specified by the cItems parameter.
Return Values
The number of items placed in the buffer indicates success. LB_ERR indicates that the list box is a single-selection list box.
