LB_GETSELITEMS message

Fills a buffer with an array of integers that specify the item numbers of selected items in a multiple-selection list box.

Parameters

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.

Return value

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.
