疑問 - 我想做個計算機請大大幫看怎麼做?

[╰。超凡者〃☆]

計算機的輸入數字欄就是最少要10　　最高是32767
這樣才能跟基本數值參考(預設對應資料),計算出來的結果一樣
當數字欄輸入10　數值欄選擇力量　則按下計算按鈕後會顯示 12物攻

例如: 10力量 = 12物攻　　那100力量就是120物攻
在程式碼上預設每一種最少輸入值是10,若低於10的話會跳出小方塊提醒。


不知道這樣做出來會不會很複雜..！




以下是我臨時製作的優惠計算機，只是不曉得該怎麼改成數值計算機！？

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim buy As Integer, pay As Integer
        Dim msg As String
        buy = Val(TextBox1.Text)
        If buy > 1000 Then
            pay = buy * 0.8
            If buy > 2000 Then
                pay = pay - 100
            Else
                pay = pay - 50

            End If
        Else
            If buy > 500 Then
                pay = buy * 0.95
            End If
        End If
        TextBox2.Text = pay


        buy = Val(TextBox1.Text)
        If buy > 1000 Then
            pay = pay * 0.8
            If buy > 2000 Then
                msg = "超過 2000 元, 先打 8 折再減 100 元。"
                pay = pay - 100

            Else

                msg = "超過 1000 元, 先打 8 折再減 50 元。"
                pay = pay - 50
            End If

        Else
            If buy > 500 Then
                msg = "金額未超過 500 元打 95 折。"
                pay = pay * 0.95
            End If
        End If
        TextBox2.Text = pay
        Label3.Text = msg
        TextBox1.Focus()
        TextBox1.SelectAll()

    End Sub
End Class
