如何用vb.net编写一个简单的计算器程序?。慷嘈话?/h2>你自己加窗体和空件吧
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()
X = Val(Text1.Text)
Y = Val(Text2.Text)
s = X / Y
Text3.Text = s
Text3.Locked = True
End Sub

如何用VB.NET编写计算器简单的说拖出一些控件，设置相应的caption和属性等等，双击每个button控件 ， 进行相应的处理，即可
vb:简易计算器（加减乘除）代码代码如下：
Dim t, t1 As Integer
Dim x, y As Double
Public Sub com()
x = Val(l1.Caption)
Select Case t1
Case Is = 1: y = y + x
Case Is = 2: y = y - x
Case Is = 3: y = y * x
Case Is = 4: y = y / x
End Select
t1 = 0
t = 0
l1.Caption = "0"
End Sub
Private Sub Form_Load()
x = 0
y = 0
t = 0
t1 = 1
End Sub
Private Sub c0_Click(Index As Integer)
If l1.Caption = "0" Then
l1.Caption = "0"
Else
l1.Caption = l1.Caption + "0"
End If
End Sub
Private Sub C1_Click(Index As Integer)
If l1.Caption = "0" Then
l1.Caption = "1"
Else
l1.Caption = l1.Caption + "1"
End If
End Sub
Private Sub c10_Click(Index As Integer)
If t = 0 Then
l1.Caption = l1.Caption + "."
t = 1
End If
End Sub
Private Sub C2_Click(Index As Integer)
If l1.Caption = "0" Then
l1.Caption = "2"
Else
l1.Caption = l1.Caption + "2"
End If
End Sub
Private Sub C3_Click(Index As Integer)
If l1.Caption = "0" Then
l1.Caption = "3"
Else
l1.Caption = l1.Caption + "3"
End If
End Sub
Private Sub C4_Click(Index As Integer)
If l1.Caption = "0" Then
l1.Caption = "4"
Else
l1.Caption = l1.Caption + "4"
End If
End Sub
Private Sub C5_Click(Index As Integer)
If l1.Caption = "0" Then
l1.Caption = "5"
Else
l1.Caption = l1.Caption + "5"
End If
End Sub
Private Sub C6_Click(Index As Integer)
If l1.Caption = "0" Then
l1.Caption = "6"
Else
l1.Caption = l1.Caption + "6"
End If
End Sub
Private Sub C7_Click(Index As Integer)
If l1.Caption = "0" Then
l1.Caption = "7"
Else
l1.Caption = l1.Caption + "7"
End If
End Sub
Private Sub C8_Click(Index As Integer)
If l1.Caption = "0" Then
l1.Caption = "8"
Else
l1.Caption = l1.Caption + "8"
End If
End Sub
Private Sub C9_Click(Index As Integer)
If l1.Caption = "0" Then
l1.Caption = "9"
Else
l1.Caption = l1.Caption + "9"
End If
End Sub
Private Sub z1_Click(Index As Integer)
com
t1 = 1
End Sub
Private Sub z2_Click(Index As Integer)
com
t1 = 2
End Sub
Private Sub z3_Click(Index As Integer)
com
t1 = 3
End Sub
Private Sub z4_Click(Index As Integer)
com
t1 = 4
End Sub
Private Sub z5_Click(Index As Integer)
tmp = Mid(l1.Caption, Len(l1.Caption), 1)
If tmp = "." Then
t = 0
End If
If Len(l1.Caption) = 1 Then
l1.Caption = "0"
Else
l1.Caption = Left(l1.Caption, Len(l1.Caption) - 1)
End If
End Sub
Private Sub z6_Click(Index As Integer)
