引言:GoldBoy 大大： 請問您有範例嗎？ 剛剛有試了，小弟功力不夠，是否可以 麻煩您寄給我或Delphi k Top 上呢？ 因為用過rave report印過，但是到另一台電腦就不能執行 直接用MScomm 控製也有中文不能列印的情形 手足無措，麻煩您 謝謝您引言: GoldBoy 大大： 小弟不懂這種方法不知道怎麼做，這該怎麼做呢？ 這劃圖的方法嗎？ 請問您有使用過QReport 裡的 Barcode 元件嗎？ 謝謝您 發表人 - jerry_go_top 於 2004/07/01 20:08:48好象QReport 裏沒有 Barcode 元件，我不太清楚，你可以用上面的代碼生成一個 Barcode 繪製元件阿~ 很靈活的，如果這樣也不行我想我幫不了你了~ |
