| Windows 95: wParam is 16-bits
|
|
|
LB_GETITEMHEIGHT
An application sends an LB_GETITEMHEIGHT message to retrieve the height of
items in a list box.
LB_GETITEMHEIGHT
wParam = (WPARAM) index; // item index
lParam = 0; // not used; must be zero
Parameters
index
Value of wParam. Specifies the zero-based index of the list box item. This index is used only
if the list box has the LBS_OWNERDRAWVARIABLE style; otherwise, it must be
zero.
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
The return value is the height, in pixels, of each item in the list box. The
return value is the height of the item specified by the index parameter if the list box has the LBS_OWNERDRAWVARIABLE style. The return
value is LB_ERR if an error occurs.
