CB_GETITEMHEIGHT
An application sends a CB_GETITEMHEIGHT message to determine the height of
list items or the selection field in a combo box.
CB_GETITEMHEIGHT
wParam = (WPARAM) index; // item index
lParam = 0; // not used; must be zero
Parameters
index
Value of wParam. Specifies the combo box component whose height is to be retrieved.
This parameter must be  1 to retrieve the height of the selection field. It must be zero to retrieve
the height of list items, unless the combo box has the CBS_OWNERDRAWVARIABLE
style. In that case, the index parameter is the zero-based index of a specific list item.
Return Values
The return value is the height, in pixels, of the list items in a combo box.
If the combo box has the CBS_OWNERDRAWVARIABLE style, it is is the height of the
item specified by the index parameter. If index is 1, the return value is the height of the edit control (or static-text) portion
of the combo box. If an error occurs, the return value is CB_ERR.
