C#实现QQ/MSN等客户端聊天软件从右下角弹出窗体(Popup Window)

源代码是从2年前写的一个项目中copy过来的，稍做修改并加注释。

1.测试窗体源代码.

学习内容: 1.委托定义 2.Invoke方法应用 3.多线程及多线程访问主线程内的控件 4.定义一个回调方法

public partial class frmTest : Form

{

delegate void AddMessageDelegate(MessageBody msg);

public frmTest()

{

InitializeComponent();

}

//定义一个MessageEventHandler委托

public void HandlingPopupWindowCallBack(object sender, MessageEventArgs e)

{

listBox1.Invoke(new AddMessageDelegate(this.AddMessage), new object[] { e.Message });

}

private void AddMessage(MessageBody msg)

{

listBox1.Items.Add("---------------------------");

listBox1.Items.Add(msg.Title);

listBox1.Items.Add(msg.Body);

}

private void btnTest_Click(object sender, EventArgs e)

{

Thread _MyThread = new Thread(new ThreadStart(PopupMessage));

_MyThread.IsBackground = true;

_MyThread.SetApartmentState(ApartmentState.MTA);

_MyThread.Start(); //啟動線程

}

/// <summary>

/// 自動彈出系統消息

/// </summary>

private void PopupMessage()

{

List<MessageBody> list = new List<MessageBody>();

list.Add(new MessageBody("测试消息1", "测试消息1的内容"));

list.Add(new MessageBody("测试消息2", "测试消息2的内容"));

list.Add(new MessageBody("测试消息3", "测试消息3的内容"));

list.Add(new MessageBody("测试消息4", "测试消息4的内容"));

frmPopupWindow window = new frmPopupWindow(this.HandlingPopupWindowCallBack, list, 1000);

window.ShowDialog();

}

2.弹出窗体源代码

public partial class frmPopupWindow : Form

{

private int _MsgIndex = 0;

private List<MessageBody> _messageList = null;

private MessageEventHandler _CallBackWhenClick;

/// <summary>

/// 重载构造器

/// </summary>

/// <param name="callBack">回调事件</param>

/// <param name="messageList">消息列表</param>

/// <param name="waitTotalTime">每个消息显示时间</param>

public frmPopupWindow(MessageEventHandler callBack, List<MessageBody> messageList,
int waitTotalTime)

{

InitializeComponent();

try

{

this.TopMost = true;

this.tmWait.Interval = waitTotalTime;

this.tmWait.Enabled = true;

this.ShowInTaskbar = false;

this.StartPosition = FormStartPosition.Manual;

this.Location = new Point(Screen.PrimaryScreen.WorkingArea.Width - this.Width - 3,
Screen.PrimaryScreen.WorkingArea.Height - this.Height);

WinAPI.AnimateWindow(this.Handle, 500, WinAPI.AW_SLIDE | WinAPI.AW_VER_NEGATIVE);

this._messageList = messageList;

this._CallBackWhenClick = callBack;

this.ShowMessage(0);

}

catch (Exception ex)

{

MessageBody msg = new MessageBody("构造器发生错误", ex.Message);

_CallBackWhenClick(null, new MessageEventArgs(msg));

}

private void btnPrior_Click(object sender, EventArgs e)

{

tmWait.Stop();

_MsgIndex -= 1;

if (_MsgIndex >= 0)

ShowMessage(_MsgIndex);

else

_MsgIndex = 0;

}

private void btnNext_Click(object sender, EventArgs e)

{

tmWait.Stop();

_MsgIndex += 1;

if (_MsgIndex <= _messageList.Count - 1)

ShowMessage(_MsgIndex);

else

_MsgIndex = _messageList.Count - 1;

}

private void btnClose_Click(object sender, EventArgs e)

{

MessageBody msg = new MessageBody("关闭弹出窗体", "用户关闭了弹出窗体.");

//测试回调事件

_CallBackWhenClick(sender, new MessageEventArgs(msg));

this.Close();

}

private void tmWait_Tick(object sender, EventArgs e)

{

if (_messageList == null) return;

if (_MsgIndex == _messageList.Count)

{

MessageBody msg = new MessageBody("消息显示完成", "系统自动关闭了弹出窗体.");

//测试回调事件

_CallBackWhenClick(sender, new MessageEventArgs(msg));

this.Close(); // close

}

else

{

ShowMessage(_MsgIndex);

_MsgIndex = _MsgIndex + 1;

}

/// <summary>

/// 显示消息

/// </summary>

private void ShowMessage(int index)

{

MessageBody msg = _messageList[index];

label1.Text = msg.Title;

label2.Text = msg.Body;

label1.Update();

label2.Update();

this.Update();

this.Refresh();

        }

3.WinAPI定义

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

namespace PopupWindow
{
   public class WinAPI
   {
      #region WinAPI Function&Const defination

      public const int AW_HOR_POSITIVE = 0x00000001;
      public const int AW_HOR_NEGATIVE = 0x00000002;
      public const int AW_VER_POSITIVE = 0x00000004;
      public const int AW_VER_NEGATIVE = 0x00000008;

      public const int AW_CENTER = 0x00000010;

      public const int AW_HIDE = 0x00010000;
      public const int AW_ACTIVATE = 0x00020000;

      public const int AW_SLIDE = 0x00040000;
      public const int AW_BLEND = 0x00080000;

      [DllImport("user32", CharSet = CharSet.Auto)]
      public static extern bool AnimateWindow(IntPtr hwnd, int dwTime, int dwFlags);

      [DllImport("Winmm")]
      public static extern bool PlaySound(string pszSound, IntPtr hmod, UInt32 fdwSound);

      private const Int32 SND_ASYNC = 1;
      private const Int32 SND_LOOP = 8;
      private const Int32 SND_FILENAME = 131072;

      #endregion

   }
}

4.公共类Common.cs

using System;
using System.Collections.Generic;
using System.Text;

namespace PopupWindow
{
   /// <summary>
   /// 消息实体类
   /// </summary>
   public class MessageBody
   {
      private string _Title;
      private string _Body;

      public MessageBody(string title, string body)
      {
         _Title = title;
         _Body = body;
      }

      public string Title { get { return _Title; } set { _Title = value; } }
      public string Body { get { return _Body; } set { _Body = value; } }
   }

   /// <summary>
   /// 自定义参数
   /// </summary>
   public class MessageEventArgs : EventArgs
   {
      private MessageBody _CurrentMessage;

      public MessageEventArgs(MessageBody currentMsg)
      : base()
      {
         _CurrentMessage = currentMsg;
      }

      /// <summary>
      /// 当前处理的消息
      /// </summary>
      public MessageBody Message
      {
         get { return _CurrentMessage; }
         set { _CurrentMessage = value; }
      }

   }

   /// <summary>
   /// 回调事件委托.用户在弹出窗体点击消息标题，触发这个事件.
   /// 学习内容: 1.自定义委托, 2.自定义委托方法的参数
   /// </summary>
   public delegate void MessageEventHandler(object sender, MessageEventArgs e);
