/*   Parameters
        nLine = Specifies the character index of a character in the line whose
        length is to be retrieved. If this parameter is -1, the length of the
        current line (the line that contains the caret) is returned, 
        not including the length of any selected text within the line.
        When LineLength is called for a single-line edit control, 
        this parameter is ignored.
