VB设计一个随机抽奖程序，当单击开始按钮时，在两个文本框产生【1，20】之间的随机整数？

假定开始按钮是 Command1，两个文本框分别是 Text1、Text2

Private Sub Command1_Click()

Randomize

Text1.Text = Int(Rnd * 20) + 1

Text2.Text = Int(Rnd * 20) + 1

End Sub

在窗体上添加一个command1，一个timer1，label1(0~5)

控件数组（添加一个label1,然后再复制5个，共6个，用来显示数字），代码如下：

Private

Sub

Command1_Click()

If

Command1.Caption

=

"抽奖"

Then

Command1.Caption

=

"停止"

Timer1.Enabled

=

True

Else

Timer1.Enabled

=

False

Command1.Caption

=

"抽奖"

End

If

End

Sub

Private

Sub

Form_Load()

Command1.Caption

=

"抽奖"

Timer1.Interval

=

50

Timer1.Enabled

=

False

End

Sub

Private

Sub

Timer1_Timer()

Randomize

For

i

Label1(i)

=

Int(10

Rnd)

Label1(i).Caption
