Fills a buffer with an array of integers that specify the item numbers of selected items in a multiple-selection list box.
-
wParam
-
The maximum number of selected items whose item numbers are to be placed in the buffer.
Windows 95/Windows 98/Windows Millennium Edition (Windows Me) : 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.
-
lParam
-
A pointer to a buffer large enough for the number of integers specified by the wParam parameter.
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.
