LB_GETSEL

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 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.

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.
