VB初心者です。 VBで（zのn乗）－（xのn乗＋yのn乗）の計算が出来るようにしたいのですが、答えが必ず-1になってしまいます。 Option Explicit On Public Class Form1 Dim x As Long Dim y As Long Dim z As Long Dim n As Long Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Me.Close() 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 Private Sub TextBox4_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox4.TextChanged End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click TextBox5.Text = (z ^ n) - (x ^ n + y ^ n) End Sub End Class 正しいコードの書き方を教えて下さい。 また特定の答えのときにメッセージを表示したいのですが、どうすればいいですか？
