求一个VB.NET进行局域网内UDP广播的源代码例子

给你个udp多播例子，广播不是很清楚，呵呵

Imports System.Net

Imports System.Net.Sockets

Imports System.Text

Public Class Form1

Inherits System.Windows.Forms.Form

Dim port As String

Dim ipadd As String

Dim ipend As IPEndPoint

Dim sendudp As New UdpClient()

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _

Handles Button1.Click

Dim ipadress As IPAddress

ipadress = IPAddress.Parse(TextBox1.Text)

'sendport = Int32.Parse(TextBox2.Text)

'ipend = New IPEndPoint(ipadress, sendport)

Try

sendudp.JoinMulticastGroup(ipadress)

MessageBox.Show("启动完成！")

Catch ex As Exception

MessageBox.Show(ex.Message)

End Try

End Sub

求vb.net的源代码，最好说明其解决问题，越多越好，满意加50分。

下面这段代码，是我用来计算每个月存500元进银行，连续30年，最后连本带利能有多少钱。这里面涉及复利计算。界面中右边的文本框用来输出每一次计算的结果。

  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

      Dim nianxian As Integer '年限变量

      Dim dingcun As Integer '定存变量

      Dim fuli_big As Long '大复利

      Dim fuli_small As Long '小复利

      Dim i As Integer '循环变量

      Dim DATAstring As String '数据字符串

      nianxian = Val(年限_TextBox.Text)

      dingcun = Val(定存_TextBox.Text)

      DATAstring = ""

      For i = 1 To nianxian

          fuli_small = dingcun * (1 + 0.1875)

          dingcun = fuli_small

          fuli_big = fuli_big + fuli_small

          DATAstring = DATAstring + "[" + Trim(Str(i)) + "]" + Str(fuli_big) + Chr(13) + Chr(10)

          'DATAstring = DATAstring + "[" + Trim(Str(i)) + "]" + Str(fuli_small) + Chr(13) + Chr(10)

      Next

      'fuli_big = fuli_small

      TextBox1.Text = DATAstring

      结果_TextBox.Text = Str(fuli_big) + "元"

  End Sub

求助一个vb.net开发的闹铃源代码，要能自定义铃声的那种

添加一个timer控件，隔一秒（Interval = 1000）对照一次本地时间和指定的时间，如果相同就执行铃声，并停止对照。 或者启动时取得本地时间，没一秒把这时间加1秒，直到加到指定的时间执行铃声，并停止加。 播放mp3的代码 System.Runtime.InteropServices.DllImport("winmm.dll", _ CharSet:=System.Runtime.InteropServices.CharSet.Auto) _Private Shared Function mciSendString(ByVal command As String, _ ByVal buffer As System.Text.StringBuilder, _ ByVal bufferSize As Integer, ByVal hwndCallback As IntPtr) As IntegerEnd FunctionPrivate aliasName As String = "MediaFile"'点击Button1（变成到指定时间就可以Private Sub Button1_Click(ByVal sender As Object, _ ByVal e As EventArgs) Handles Button1.Click '要播放的文件比如在C:\music.mp3 Dim fileName As String = "C:\music.mp3" Dim cmd As String '打开文件代码 cmd = "open """ + fileName + """ type mpegvideo alias " + aliasName If mciSendString(cmd, Nothing, 0, IntPtr.Zero) 0 Then Return End If '播放 cmd = "play " + aliasName mciSendString(cmd, Nothing, 0, IntPtr.Zero)End Sub'点击Button2停止播放（根据你自己的情况，比如建一个停止的按钮Private Sub Button2_Click(ByVal sender As Object, _ ByVal e As System.EventArgs) Handles Button2.Click Dim cmd As String '播放中音乐停止 cmd = "stop " + aliasName mciSendString(cmd, Nothing, 0, IntPtr.Zero) '关闭 cmd = "close " + aliasName mciSendString(cmd, Nothing, 0, IntPtr.Zero)End Sub
