以下的副程式的功用為: 在 WORD 中設定書籤.
其工作方式乃是透過 Type Library, 而不是 Variant 物件.
-----------------------------------------------------------
function TWordObj.setBookmark(bkmrkName: widestring; text:
wideString):boolean;
var
  i: integer;
  bkmark: word_TLB.Bookmark;
  temp: oleVariant;
begin
  for i:= 1 to fmydoc.Bookmarks.Count  do
  begin
    temp := oleVariant(i);
    bkmark := fmydoc.bookmarks.Item(temp);
    if bkmark.Name = bkmrkname then
    begin
      bkmark.Range.Set_Text(text);
      exit;
    end;
  end;
end;
