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

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))
