马上要过圣诞了！
公司办公室的要组织一次活动，要求做个抽奖程序，想用VB做个无重复的抽奖程序，抽奖活动分一等奖，二等奖，三等奖，分3次抽出，每次抽一人，怎么才能实现无重复抽取呢？没人只有一次中奖机会。请各位帮帮忙呀！

这样：窗体上放一个可以输入人数的文本编辑框，一个 Label，一个 ComboBox，两个按钮（启动，停止）。
Option Explicit
Dim k As Integer

Private Sub Command1_Click()
Text1.Locked = True

Label1.Caption = IIf(k = 1, "一", IIf(k = 2, "二", "三")) & "等奖"
Timer1.Enabled = True
End Sub

Private Sub Command2_Click()
Dim n As Integer

Timer1.Enabled = False
Randomize
n = Rnd * Combo1.ListCount
Text1 = Combo1.List(n - 1)
Combo1.RemoveItem n

k = k - 1
If k = 0 Then
Command1.Enabled = False
Command2.Enabled = False
End If
End Sub

Private Sub Form_Load()
Dim i As Integer
For i = 1 To Val(Text1)
Combo1.AddItem i
Next i
Combo1.Visible = False
Timer1.Enabled = False
Timer1.Interval = 50

Label1.Font.Size = 24
Label1.Alignment = 2
Label1.AutoSize = True
Label1 = "三等奖"

Text1.Alignment = 2
Text1.Font.Size = 24
Text1.Font.Bold = True

k = 3
End Sub

Private Sub Timer1_Timer()
Dim p As Integer

Randomize
p = Rnd * Combo1.ListCount
Text1 = Combo1.List(p - 1)
End Sub
