ActiveMQ Demo程序，包括发送和接收程序
ActiveMQ是个好东东，不必多说。ActiveMQ提供多种语言支持，如Java, C, C , C#, Ruby, Perl, Python, PHP等。由于我在windows下开发GUI，比较关心C 和C#，其中C#的ActiveMQ很简单，Apache提供NMS（.Net Messaging Service）支持.Net开发，只需如下几个步骤即能建立简单的实现

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace MQDemoProducer
{
    public partial class Form1 : Form
    {
        private MQ m_mq;
        private List<Property> m_lstProperty = new List<Property>();

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            lv.Columns.Clear();
            ListViewCtrl.SetListViewStyle(ref lv);

            lv.Columns.Add("属性名称", "Property Name", 150, HorizontalAlignment.Left, 0);
            lv.Columns.Add("属性值", "Property Value", 150, HorizontalAlignment.Left, 0);

        }

        private void btnConnect_Click(object sender, EventArgs e)
        {
            try
            {
                if (!GlobalFunction.CheckControlInput(txtURI, "URI", 0, false)) return;

                m_mq = new MQ();
