請問各位大大，我寫的是關於最短路徑的    當中有一些值是需要連資料庫的    如程式中的 double road_time;            ADOTable1->Open();           road_time=ADOTable1->Fields->Fields[0] ->AsInteger ;    雖然可以執行，但偵錯時數值只要是road_time此值    都會指向資料庫中的第九筆，也就是35    我已經有寫ADOTable1->First();    然後下一筆則是ADOTable1->Next();    但數值都會出來的結果都是以第九筆數值下去計算。    想請問各位大大，我是不是有哪裡寫錯了呢？？
