急急急！C#socket 编程，如何实现当客户端发来消息时，有提示音？就像qq一样!有劳大神了！
我知道调用Consol.Beep（）函数，但是，这个函数 该放在哪里呢 ？代码如下：namespace TCPServer
{
public partial class frmSyncTcpServer : Form
{
#region 变量
// 申明变量
private const int Port = 9000;
private TcpListener tcpLister = null;
private TcpClient tcpClient = null;
IPAddress ipaddress;
private NetworkStream networkStream = null;
private BinaryReader reader;
private BinaryWriter writer;
// 申明委托
// 显示消息
private delegate void ShowMessage(string str);
private ShowMessage showMessageCallback;
// 显示状态
private delegate void ShowStatus(string str);
private ShowStatus showStatusCallBack;
// 清空消息
private delegate void ResetMessage();
private ResetMessage resetMessageCallBack;
public class BeepUp //新建一个类
{
System.Runtime.InteropServices;
public static extern bool Beep(int frequency, int duration);
}
#endregion
public frmSyncTcpServer()
{
InitializeComponent();
#region 实例化委托
// 显示消息
showMessageCallback = new ShowMessage(showMessage);
// 显示状态
showStatusCallBack = new ShowStatus(showStatus);
// 重置消息
resetMessageCallBack = new ResetMessage(resetMessage);
#endregion
ipaddress = IPAddress.Loopback;
tbxserverIp.Text = ipaddress.ToString();
tbxPort.Text = Port.ToString();
}
#region 定义回调函数
// 显示消息
private void showMessage(string str)
{
lstbxMessageView.Items.Add(tcpClient.Client.RemoteEndPoint);
lstbxMessageView.Items.Add(str);
lstbxMessageView.TopIndex = lstbxMessageView.Items.Count - 1;
}
// 显示状态
private void showStatus(string str)
{
toolStripStatusInfo.Text = str;
}
// 清空消息
private void resetMessage()
{
tbxMessage.Text = string.Empty;
tbxMessage.Focus();
}
#endregion
#region Click事件
// 开始监听

{
tcpLister = new TcpListener(ipaddress,Port);
tcpLister.Start();
// 启动一个线程来接受请求

}
// 接受请求

{

C# --------------------编程问答-------------------- 最简单的
System.Media.SystemSounds.Beep.Play();
System.Media.SystemSounds.Asterisk.Play();
System.Media.SystemSounds.Exclamation.Play(); --------------------编程问答-------------------- 在客户端接受到消息成功的时候调用播放音乐的win32api --------------------编程问答-------------------- 也可以用SoundPlayer播放任意声音
http://www.cnblogs.com/buzaixian/archive/2009/09/19/1570116.html --------------------编程问答-------------------- 我的意思是说：在点击”接受“按钮前先发出提示声音！该怎么办呢？我现在的情况是：在点击接受按钮时才发出声音...
求帮忙！谢谢 --------------------编程问答-------------------- 用VB做过 C#的倒是没用过。 --------------------编程问答--------------------
一个笨办法 在服务器上放个timer控件 定时调用
// 接受请求
private void acceptClientConnect()
这个就行
补充：.NET技术 , C#
