12套VB操作题程序代码

1、更改对象属性

Private Sub Command1_Click()

Form1.Caption = "对象的属性" '代码1 Label1.Caption = "这是一个标签" '代码2 5、交换两个变量的值

Dim x, y As Integer

Private Sub Command1_Click() Dim z As Integer

z = x '代码1 x = y

Text1.Text = "这是一个文本框" End Sub 2、VB函数

Private Sub Command1_Click()

Text1.Text = Abs(-5) '代码1 Text2.Text = Int(3.5) '代码2 Text3.Text = Sqr(16) End Sub 3、抽取幸运同学

Private Sub Form_Load()

a = InputBox("请输入你们班级总人数") 'End Sub

Private Sub Command1_Click() b = Int(Rnd * a) + 1

Text1.Text = b 'End Sub

4、反向输出三位数

Dim x As Integer 'Private Sub Command1_Click() Dim A, B, C As Integer

A = Int(x / 100) 'B = Int((x - A * 100) / 10) C = x - A * 100 - B * 10 Label1.Caption = C & B & A End Sub

Private Sub Form_Load()

x = InputBox("请输入一个三位数：") End Sub

代码1 代码2 代码1 代码2 y = z '代码2

Label2.Caption = "x的值为" & x & ",y的值为" & y End Sub

Private Sub Form_Load()

x = InputBox("请输入x的值：") y = InputBox("请输入y的值：")

Label1.Caption = "x的值为" & x & ",y的值为" & y End Sub 6、计算器

Private Sub Command1_Click() Label1.Caption = "+"

Text3.Text = Val(Text1.Text) + Val(Text2.Text) End Sub

Private Sub Command2_Click()

Label1.Caption = "-" 'Text3.Text = Val(Text1.Text) - Val(Text2.Text) 'End Sub

Private Sub Command3_Click() Label1.Caption = "*"

Text3.Text = Val(Text1.Text) * Val(Text2.Text) End Sub

Private Sub Command4_Click() Label1.Caption = "/"

Text3.Text = Val(Text1.Text) / Val(Text2.Text) End Sub

代码1 代码2
Private Sub Command5_Click() Text1.Text = "" Text2.Text = ""

Text3.Text = "" '代码3 End Sub

7、判断1—100之间整数的奇偶性

Private Sub Command1_Click()

Randomize '代码1 x = Int(Rnd * 100) + 1

If x Mod 2 = 0 Then '代码2 Print x; "是一个偶数"

Else '代码3 Print x; "是一个奇数" End If End Sub

8、为希望工程捐款

Private Sub Command1_Click() s = 0

For i = 1 To 12 '代码1 s = s + i '代码2 Next i

Label2.Caption = "感谢您！一年您共为希望工程捐款" & Str(s) & "元!" End Sub 9、求矩形面积

Private Sub Command1_Click() a = Val(Text1.Text)

b = Val(Text2.Text) '代码1 s = a * b '代码2 Label3.Caption = "矩形的面积为：" & s End Sub 10、计算器

Private Sub Command1_Click() L1.Caption = "+"

T3.Text = Val(T1.Text) + Val(T2.Text) End Sub

Private Sub Command2_Click() L1.Caption = "-"

T3.Text = Val(T1.Text) - Val(T2.Text) End Sub

Private Sub Command3_Click() L1.Caption = "*"

T3.Text = Val(T1.Text) * Val(T2.Text) End Sub

Private Sub Command4_Click()

L1.Caption = "/" '代码1 T3.Text = Val(T1.Text) / Val(T2.Text) '代码2 End Sub '代码3 11、抽取幸运同学

Private Sub Command1_Click() Label2.Visible = True

Text2.Visible = True '代码1 Randomize

Text2.Text = Int(Rnd * Val(Text1.Text) + 1) '代码2 End Sub 12、累加求和

Dim i, s, n As Integer

Private Sub Command1_Click() s = 0

n = Val(Text1.Text)

For i = 1 To n Step 1 '代码1 s = s + i '代码2 Next i

Text2.Text = s '代码3 End Sub
