LB_GETSELITEMS Overview  Group

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.
