前回はとっても助かりました
ありがとうございました
今度はグリッドのデータを項目に表示する時の確認です
よろしくお願いいたします

アクセスフィールド
SubjectNo   長整数型
ClassNo     テキスト型
Kind        バイト型
CheckFl     Yes/No型

＊＊＊ グリッド表示(下記の順）　＊＊＊
   SubjectNo     ClassNo      Kind    CheckFl(Yes/No)

　　ここで質問ですが、上記のロジックでグリッドの内容を各項目に表示させることが可能
    ですので目的は達成です。
　　しかしながら、一度データテーブルに抽出したデータを利用せずに、直接データベース
    よりもってくるロジックなので、しっくりきません。
　　作業効率的にはどうなのでしょうか。
　　もっと良い方法がありましたらよろしくお願いいたします。
