このプログラムは 例えば３ ３ ４とテキストボックスに数字が打ち込まれると ３×３行列が４個分 のテキストボックスがでてきます。 ここに数字を打ち込んでいき、ボタン２を押すと３×３のテキスト トボックスが出てくると同時に足し算した結果が出てくるようにしたいです。 以下のプログラムはできたところまで作成しています。 どこを直せばよいのでしょうか。 Public Class Form1 Private number As Integer Private rows As Integer Private columns As Integer Private Sub Form11_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load For i As Integer = 1 To 3 AddHandler Me.Controls("TextBox" & i).TextChanged, AddressOf TextBox_TextChanged Next End Sub Private Sub TextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) If System.Text.RegularExpressions.Regex.IsMatch(CType(sender, TextBox).Text, "[^0-9]") Then MessageBox.Show("数字で入力してください", Me.Text, MessageBoxButtons.OK, MessageBoxIcon.Error) With CType(sender, TextBox) .Text = .Text.Substring(0, .Text.Length - 1) .SelectionStart = .Text.Length End With End If Dim cnt1 As Integer Dim cnt2 As Integer Dim cnt3 As Integer If Integer.TryParse(TextBox1.Text, cnt1) And Integer.TryParse(TextBox2.Text, cnt2) And Integer.TryParse(TextBox3.Text, cnt3) Then For k = 1 To cnt3 For i = 1 To cnt1 For j = 1 To cnt2 Dim tb As TextBox = New TextBox() tb.Name = "tb" + i.ToString() Me.Controls.Add(tb) tb.Top = (i - 1) * 28 + 55 tb.Left = (j - 1) * 30 + 40 * (cnt2 * (k - 1)) + 10 tb.Width = 25 Next Next Next End If End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Bounds = New Rectangle(10, 10, 1350, 800) Me.AutoScroll = True End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim sum As Double Dim cnt As Integer = 0 For i As Integer = 1 To rows For j As Integer = 1 To columns Dim tb As TextBox = New TextBox() cnt += 1 : If cnt > rows * columns Then cnt = 1 tb.Name = "tb" + cnt.ToString Me.Controls.Add(tb) tb.Top = (i - 1) * 30 + (80 + 40 * rows) tb.Left = (j - 1) * 60 + 10 tb.Width = 40 sum = 0 For k As Integer = 1 To number sum += Double.Parse(CType(Me.Controls("tb" + (cnt + (rows * columns * (k - 1))).ToString()), TextBox).Text) Next tb.Text = sum.ToString() Next Next End Sub Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged End Sub Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged End Sub Private Sub TextBox3_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox3.TextChanged End Sub End Class
