小信使功能实现新邮件提示,MSN一样的方法弹出的实现方法

MSN有信息或邮件时,会缓慢出现一个信息窗口. 其实不难,E8.Net平台中 开发的项目中有做个小信使功能. 提示方式类似MSN有新信息来一样.

首先: 有个窗体 form1.aspx 实现小图标 出现在 右下脚.
关键点: 窗体Opacity 属性 设置为 0% 隐藏
放置一个控件 NotifyIcon ,实现右下角图标功能

菜单代码:


private void Form1_Load(object sender, EventArgs e)






{


MenuItem menuItem1 = new MenuItem("未读邮件");


MenuItem menuItem2 = new MenuItem("待办事项");


MenuItem menuItemP2 = new MenuItem("-");


MenuItem menuItem6 = new MenuItem("切换用户");


MenuItem menuItemP1 = new MenuItem("-");


MenuItem menuItem4 = new MenuItem("退出程序");


//分别为4个菜单项添加Click事件响应函数


menuItem1.Click += new System.EventHandler(this.menuItem1_Click);


menuItem2.Click += new System.EventHandler(this.menuItem2_Click);


menuItem4.Click += new System.EventHandler(this.menuItem4_Click);


menuItem6.Click += new EventHandler(menuItem6_Click);


//设置NotifyIcon对象的ContextMenu属性为生面的弹出菜单对象






niTools.ContextMenu = new ContextMenu(new MenuItem[]

{ menuItem1, menuItem2, menuItemP2, menuItem6, menuItemP1, menuItem4 });




InitBrowserInterface();












}



提示窗口实现:
当有新邮件时:


FrmShowEmail frm = new FrmShowEmail();


frm.Opener = this;


frm.EmailCount = iEmailCnt;


frm.EmailSubject = strEmailSubject;


frm.EmailFrom = strEmailFrom;


frm.EmailDate = dtLastEmail.ToString("yyyy-MM-dd hh:mm");


frm.HeightMax = 180;//窗体滚动的高度


frm.WidthMax = 268;//窗体滚动的宽度


frm.ScrollShow();



实现的慢慢弹出的关键代码在 frmShowEmail.aspx中
放置了三个时间控件 Timer1 Timer2 Timer3 分别设置 Interval = 60 100 60
关键代码:


private void FrmShowEmail_Load(object sender, EventArgs e)






{


Screen[] screens = Screen.AllScreens;


Screen screen = screens[0];//获取屏幕变量


this.Location = new Point(screen.WorkingArea.Width - widthMax - 20, screen.WorkingArea.Height - 34);//WorkingArea为Windows桌面的工作区


this.timer2.Interval = StayTime;




}




public void ScrollShow()






{




Application.DoEvents();


this.Width = widthMax;


this.Height = 0;






this.Show();




this.timer2.Enabled = false;


this.timer3.Enabled = false;


this.timer1.Enabled = true;




}




private void ScrollUp()






{


if (Height < heightMax)






{


this.Height += 3;


this.Location = new Point(this.Location.X, this.Location.Y - 3);


}


else






{


this.timer1.Enabled = false;


this.timer2.Enabled = true;


}


}




private void ScrollDown()






{


if (Height > 40)






{


this.Height -= 3;


this.Location = new Point(this.Location.X, this.Location.Y + 3);


}


else






{


this.timer3.Enabled = false;


this.Close();


this.Dispose();


}


}




private void timer1_Tick(object sender, System.EventArgs e)






{


ScrollUp();


}




private void timer2_Tick(object sender, System.EventArgs e)






{


timer2.Enabled = false;


timer3.Enabled = true;


}




private void timer3_Tick(object sender, System.EventArgs e)






{


ScrollDown();


}

这样就实现了类似MSN的方式提示新邮件和新的待办事项.
