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

Form_Load()
Command1.Caption
=

Timer1.Interval
=

Timer1.Enabled

False
End

vb.net 多次滚动抽奖的程序代码
我用多线程写的，你可以参考下。
系统界面图如下：（注：重置功能为清除已经中奖号码，回归1-100都可以中奖状态。）
代码：
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
System.Threading.Thread g_Thread = null;
Listint g_list = new Listint();
int g_Num = 0;
delegate void g_delegate();
/// summary
/// 开始
/// /summary
/// param name="sender"/param
/// param name="e"/param
private void button2_Click(object sender, EventArgs e)
{
if(g_list.Count==100)
{
MessageBox.Show("所有数字已使用，请重置！");
return;
}
button3.Enabled = true;
Random r = new Random();
g_delegate dele= ChangeTxt;
g_Thread = new System.Threading.Thread(() =
{
while(this.IsDisposed==false)
{
g_Num = r.Next(1, 100);
if(g_list.Contains(g_Num))
{
g_Num = 1;
}
while(g_list.Contains(g_Num))
{
g_Num++;
}
this.Invoke(dele);
System.Threading.Thread.Sleep(50);
}
});
g_Thread.Start();
}
void ChangeTxt()
{
label2.Text = g_Num.ToString();
}
/// summary
/// 停止
/// /summary
/// param name="sender"/param
/// param name="e"/param
private void button3_Click(object sender, EventArgs e)
{
//if(g_Thread.ThreadState==System.Threading.ThreadState.Running)
{
g_Thread.Abort();
g_list.Add(Convert.ToInt32(label2.Text));
}
button3.Enabled = false;
}
/// summary
/// 重置
/// /summary
/// param name="sender"/param
/// param name="e"/param
private void button1_Click(object sender, EventArgs e)
{
g_list.Clear();
}
private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
System.Environment.Exit(0);
}
}
VB编程年会抽奖代码？
语言实现此程序。
以下是VB编程语言的实现示例：
'定义变量，存储每个奖项的人数
Dim firstPrize As Integer = 3
Dim secondPrize As Integer = 5
Dim thirdPrize As Integer = 12
Dim souvenirPrize As Integer = 10
'定义变量，存储抽奖结果
Dim firstPrizeList As New List(Of Integer)
Dim secondPrizeList As New List(Of Integer)
Dim thirdPrizeList As New List(Of Integer)
Dim souvenirPrizeList As New List(Of Integer)
'定义变量，存储编号滚动的起始编号
Dim currentNum As Integer = 1
'循环抽取各种奖项
For i As Integer = 1 To firstPrize
'抽取一等奖，并将编号添加到一等奖名单中
firstPrizeList.Add(currentNum)
currentNum += 1
Next
For i As Integer = 1 To secondPrize
'抽取二等奖，并将编号添加到二等奖名单中
secondPrizeList.Add(currentNum)
currentNum += 1
Next
For i As Integer = 1 To thirdPrize
'抽取三等奖，并将编号添加到三等奖名单中
thirdPrizeList.Add(currentNum)
currentNum += 1
Next
For i As Integer = 1 To souvenirPrize
'抽取纪念奖，并将编号添加到纪念奖名单中
souvenirPrizeList.Add(currentNum)
currentNum += 1
Next
'输出抽奖结果
Console.WriteLine("一等奖名单：" String.Join(",", firstPrizeList))
Console.WriteLine("二等奖名单：" String.Join(",", secondPrizeList))
Console.WriteLine("三等奖名单：" String.Join(",", thirdPrizeList))
Console.WriteLine("纪念奖名单：" String.Join(",", souvenirPrizeList))
