LB_GETSEL  PKAR6N 

An application sends an LB_GETSEL message to retrieve the selection state of an item.

LB_GETSEL

wParam = (WPARAM) index;    // item index

lParam = 0;                 // not used; must be zero

Parameters

index

Value of wParam. Specifies the zero-based index of the item.

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.

Return Values

If an item is selected, the return value is greater than zero; otherwise, it is zero. If an error occurs, the return value is LB_ERR.
