windows mobile添加任务栏图标

本文讲的是在net cf下给windows mobile添加任务栏图标的两种方式：

1、P/Invoke

using System.Collections.Generic;

using System.Runtime.InteropServices;

            messageWindow.uID = uID;

        public void Add()
        {

            {

            }
        }
        /// <summary>

                        }
                    }
                }
            }
        }
        #endregion
    }
}

 

需要导入Microsoft.WindowsCE.Forms类库。

 

在Form中调用：

public partial class MainForm : Form
    {
        // 注意,定义的是全局变量。
        NotifyIcon notifyIcon;

        public MainForm()
        {
            InitializeComponent();

            InitNotifyIcon();  
        }

        private void notifyIcon_Click(object sender, EventArgs e)
        {
            MessageBox.Show("Icon Clicked!");
        }  

        /// <summary>   
        /// 设置任务栏图标。   
        /// </summary>          
        private void InitNotifyIcon()   
        {
            notifyIcon= new NotifyIcon();
            // 添加图标对象
              notifyIcon.Add(this.Icon);
            notifyIcon.Click += new EventHandler(notifyIcon_Click);
        }


        private void menuItemClose_Click(object sender, EventArgs e)
        {
            this.Close();
            // 删除图标对象
              notifyIcon.Remove();
        }   
    }

2、使用OpenNetCF 推出的 Smart Device Framework （ SDF ）类库中的 NotifyIcon 类来完成。

OpenNetCF 的官方网址是 http://www.opennetcf.com/ ，你可以点击这个地址

http://www.opennetcf.com/Products/SmartDeviceFramework/tabid/65/Default.aspx 下载 Smart Device Framework

（ SDF ）最新版本 2.3 ，它分为社区版（免费），标准版（ $50 ），专业版（ $500 ），后两个版本只支持

Visual Studio 2008 ，而免费的社区版同时还支持 Visual Studio 2005 。社区版与收费版本最大的区别我认为是没有设计时支持，

而 SDF 中只有少量的控件类，所以设计时支持也显得不是那么必要了。下载安装完成后，在visual studio中添加对

OpenNETCF.Windows.Forms.dll的引用，在安装目录下的Bin目录下。

 

使用：

using OpenNETCF.Windows.Forms;

public partial class MainForm : Form
    {
        // 注意,定义的是全局变量。
        NotifyIcon notifyIcon;

        public MainForm()
        {
            InitializeComponent();

            InitNotifyIcon();  
        }

        private void notifyIcon_Click(object sender, EventArgs e)
        {
            MessageBox.Show("Icon Clicked!");        
        }  

        /// <summary>   
        /// 设置任务栏图标。   
         /// </summary>   
        private void InitNotifyIcon()   
        {
            notifyIcon = new NotifyIcon();
            // 单击事件。   
              notifyIcon.Click += new EventHandler(notifyIcon_Click);
            notifyIcon.Icon = this.Icon; // 这里通过引用窗体的图标对Icon属性赋值。   
              notifyIcon.Text = "Mobile";
            notifyIcon.Visible = true;
        }
    }
