关于WinCe托盘做法

前段时间做一个 WinCe的小程序，用来检测ZigBee网络信号。有显示系统托盘(NotifyIcon)的需求、

 

开始了。

 

首页准备一个托盘的类  NotifyIcon.cs 

using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace WinCeSerial.NotifyClient
{
    /// <summary>
    /// 智能设备托盘图标类
    /// </summary>
    public class NotifyIcon
    {
        //单击事件
        public event System.EventHandler Click;

        private MyMessageWindow messageWindow;
        private int uID = 5000;
        private System.Drawing.Icon _Icon;
        
        public NotifyIcon()
        {
            messageWindow = new MyMessageWindow(this);
            messageWindow.uID = uID;
        }
        public System.Drawing.Icon Icon
        {
            set
            {
                _Icon = value;

            }
        }
      
        ~NotifyIcon()
        {
            Remove();
        }

        /// <summary>

        }
        /// <summary>
        /// 添加托盘图标；icon为属性中的icon
        /// </summary>
        public void Add()
        {
            if (_Icon != null)

    }
}

 

接下来就是 使用这个托盘类了。

 SortedList table = new SortedList();
        //int iCount = 0;
        //Assembly asm;
        string strRes;//接受的内容
        int netCount = 0;
        int caseValue = 0; //0 已经关闭网络; 1已经开启网络
        NotifyIcon notifyicon;
        System.Drawing.Icon icon;
        public frmSignMain()
        {
            InitializeComponent();

            //notifyicon = new NotifyIcon();
            //notifyicon.Click += new EventHandler(notifyicon_Click);
            //Assembly asm = Assembly.GetExecutingAssembly();
            //icon = new Icon(asm.GetManifestResourceStream("WinCeSerial.Properties.00.ico"));

            //notifyicon.Icon = icon;

            //notifyicon.Add();
        }

        void notifyicon_Click(object sender, EventArgs e)
        {
            //if (caseValue == 1)
            //{
            //    MessageBox.Show("ZigBee信号:" + cbLevel.Text);
            //}
            //else
            //{
            //    MessageBox.Show("未检测到信号.");
            //}



 //切换托盘
            notifyicon.Remove();
            caseValue = 0;
            notifyicon = new NotifyIcon();
            notifyicon.Click += new EventHandler(notifyicon_Click);
            Assembly asm = Assembly.GetExecutingAssembly();
            icon = new Icon(asm.GetManifestResourceStream("WinCeSerial.Properties.gray.ico"));
            notifyicon.Icon = icon;
            notifyicon.Add();
        }

好了，就这些，代码有些没用的变量自己去掉即可。
