Dim A, B, C
A = 10
B = 3
C = f(A) / (f(B) * f(A - B))
Print C
End Sub
Private Function f(n)
Dim I As Integer
f = 1
For I = 1 To n
f = f * I
Next I
End Function
跪求:VB.net加减乘除 代码
先在form上建立三个textbox，分别为textbox1,textbox2,textbox3，再建立四个按钮，分别为cmdplus,cmdminus,cmdmultiple,cmddivide，代码如下：
Private Sub cmdplus_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdplus.Click
Dim a As Integer
Dim b As Integer
a = TextBox1.Text
b = TextBox2.Text
TextBox3.Text = a + b
End If
Private Sub cmdminus_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdminus.Click
Dim a As Integer
Dim b As Integer
a = TextBox1.Text
b = TextBox2.Text
TextBox3.Text = a - b
End If
Private Sub cmdmultiple_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdmultiple.Click
Dim a As Integer
Dim b As Integer
a = TextBox1.Text
b = TextBox2.Text
TextBox3.Text = a * b
End If
Private Sub cmddivide_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmddivide.Click
Dim a As Integer
Dim b As Integer
a = TextBox1.Text
b = TextBox2.Text
TextBox3.Text = a / b
End If
vb.net中把两个参数相乘用什么符号

vb.net中把两个参数相乘用 * 符号来表示相乘，用 / 符号表示相除。
VB.NET 怎样编写使用Do While 循环输出1-10的阶乘，我是新手请加上文字说明，呵呵，谢谢各位了！
首先在窗体上画两个控件：TextBox1和Button1
TextBox1用来输入需要计算那个数的阶乘
双击Button1进入输入代码，代码如下
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Try
Dim Factorial As Integer = 1 '定义一个变量用来记录阶乘的结果
Dim count As Integer '定义一个变量用来记录需要计算那个数的阶乘
Dim i As Integer = 1 '定义一个数用来循环
count = Int(Val(Me.TextBox1.Text)) '把TextBox1的值赋值给count
Do While i = count '下面开始计算阶乘
Factorial = Factorial * i '计算阶乘
i += 1 '自增1
Loop
MessageBox.Show(Int(Val(Me.TextBox1.Text)) "的阶乘是：" Factorial, "完成", MessageBoxButtons.OK) '弹出计算结果
Catch ex As Exception '出错提示
MessageBox.Show(Err.Description, "出错了", MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try
End Sub
