学生の年 ( stuyear) を参照する以下のケース ステートメントをセットアップしました (最終的には asp.net コントロールによってトリガーされます。ケースは、結果を 3 つの列に出力するときに計算にこれを含めるようにセットアップされています。ただし、出力列が 0 を返すように、stuyear範囲内の値をmaindata11 から 10 に変更すると、ステートメントは最初の 3 つのケースでのみ有効であるように見え、最後の 6 つのケースでは、それらが無視されているかのように 0 を返します。
私がしたいことは、が、、stuyearの内容を変更したときです。belowexpectedasexpectedaboveexpected
9 年、10 年、11 年に別々の列を設定して、回避できる場合は VB.net でそれらの可視性をトリガーしたくありません。
/*Progress*/以下のコメントの下の例で、私が参照している特定のコードを見つけることができます。
