如何用vb.net編寫一個簡單的計算器程序啊？多謝啊

你自己加窗體和空件吧

Private Sub a1_Click()

X = Val(Text1.Text)

Y = Val(Text2.Text)

s = X + Y

Text3.Text = s

Text3.Locked = True

End Sub

Private Sub a2_Click()

X = Val(Text1.Text)

Y = Val(Text2.Text)

s = X - Y

Text3.Text = s

Text3.Locked = True

End Sub

Private Sub a3_Click()

X = Val(Text1.Text)

Y = Val(Text2.Text)

s = X * Y

Text3.Text = s

Text3.Locked = True

End Sub

Private Sub a4_Click()

不會的叫我 在線談

VB.NET怎么編模擬袖珍計算器的完整程序？

Public C護激篙刻蕻灸戈熏恭抹lass Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim c As Char

c = Trim(TextBox3.Text)

Select Case c

Case "+"

TextBox4.Text = Val(TextBox1.Text) + Val(TextBox2.Text)

Case "-"

TextBox4.Text = Val(TextBox1.Text) - Val(TextBox2.Text)

Case "*"

TextBox4.Text = Val(TextBox1.Text) * Val(TextBox2.Text)

Case "\"

If Val(TextBox2.Text) = 0 Then

MsgBox("分母為0")

Else

TextBox4.Text = Val(TextBox1.Text) \ Val(TextBox2.Text)

End If

Case "/"

If Val(TextBox2.Text) = 0 Then

MsgBox("分母為0")

Else

TextBox4.Text = Val(TextBox1.Text) / Val(TextBox2.Text)

End If

End Select

您好 ，我想用vb。net編一個計算器，就是設置了幾個數(shù)字鍵，摁一下顯示一個數(shù)字，比如輸入67該怎么編寫

操作過程:

1獲取你摁的第一個數(shù)字值,比如6,把它轉換成字符串"6",設置在文本框txtNum中.

2獲取你按的第二個數(shù)字值,比如7,轉換成字符串,設置文本框

txtNum.text += "7" 這樣就出現(xiàn)了"67"的顯示了.
