Private Sub Form_Click()
Dim a$, amn%, amx%, a1%, a2%, a3%, rmn%, rmx%
a = 1
Do While Len(a) <> 3 Or Not IsNumeric(a)
a = InputBox("输入一个三位数")
a = Trim(a)
Loop

a1 = Int(Val(a) / 100)
a2 = Int(Val(a) / 10) - 10 * a1
a3 = Val(a) - 100 * a1 - 10 * a2
amx = (a1 + a2) / 2 - Abs(a1 - a2) / 2
amn = (a2 + a3) / 2 - Abs(a2 - a3) / 2
rmn = (amx + amn) / 2 - Abs(amx - amn) / 2
Print a; ":"; rmn,
amx = (a1 + a2) / 2 + Abs(a1 - a2) / 2

定义2个文本框TextBox1和TextBox2和一个button1，然后输入如下代码
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim b1 As Integer
Dim b2 As Integer
Dim b3 As Integer
b1 = CType(TextBox1.Text.Substring(0, 1), Integer)
b2 = CType(TextBox1.Text.Substring(1, 1), Integer)
b3 = CType(TextBox1.Text.Substring(2, 1), Integer)
If b1 > b2 Then jiaohuan(b1, b2)
If b2 > b3 Then jiaohuan(b2, b3)
If b1 > b2 Then jiaohuan(b1, b2)
TextBox2.Text = CType(b1, String) & CType(b2, String) & CType(b3, String)
End Sub
Private Sub jiaohuan(ByRef a As Integer, ByRef b As Integer)
a = a + b
b = a - b
a = a - b
End Sub
运行后在TextBox1里输入数字按button，TextBox2里就是输出结果。
此程序VS2008 VB.NET调试通过。

你要是能搞清楚这个逻辑关系~那么恭喜你VB入门了~要是不理解 那么遗憾告诉你~你得好好学学 数学了。
