VB.NET怎么编模拟袖珍计算器的完整程序？Public C护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

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 = XY
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
不会的叫我在线谈
您好，我想用vb 。net编一个计算器，就是设置了几个数字键，摁一下显示一个数字，比如输入67该怎么编写操作过程:
1获取你摁vb.net数学计算器的第一个数字值,比如6,把它转换成字符串"6",设置在文本框txtNum中.
2获取你按vb.net数学计算器的第二个数字值,比如7,转换成字符串,设置文本框
txtNum.text= "7" 这样就出现了"67"的显示了.

有关vb.net制作计算器的问题判断吧，如果点击按钮，则一个全局变量为1 ， -按钮，则全局变量为2.以此类推，然后if或case判断哪个数，如果为1 ，就两个数相加。
