自动提醒功能

用FORM实现

C# code

实现类似MSN好友上线的提示设置两个窗体：form2（即好友上线提示的容器） ：代码：using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace MSN{    public partial class Form2 : Form    {        public Form2()        {            InitializeComponent();        }        private int heightMax, widthMax;        public int HeightMax        {            set            {                heightMax = value;            }            get            {                return heightMax;            }        }        public int WidthMax        {            set            {                widthMax = value;            }            get            {                return widthMax;            }        }        //Timer1控制窗体滚出的动画，timer2控制窗体停留时间，timer3控制窗体的滚入动画        public void ScrollShow()        {            this.Width = widthMax;            this.Height = 0;            this.Show();            this.timer1.Enabled = true;        }        public int StayTime = 5000;      int a = 30;        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;            }                       //if (a  <= heightMax * 8 )            //{            //    a += 3;            //    this.Height = 35 ;            //    this.Location = new Point(this.Location.X, this.Location.Y - 3);            //    if(this.Location.X > 500 )            //    {                                //            this.Location = new Point(this.Location.X - 3, this.Location.Y);                                                   //    }            //}                  }        private void ScrollDown()        {            if (Height > 3)            {                this.Height -= 3;                this.Location = new Point(this.Location.X, this.Location.Y + 3);            }            else            {                this.timer3.Enabled = false;                this.Close();            }        }        private void timer3_Tick(object sender, EventArgs e)        {            ScrollDown();        }        private void timer1_Tick(object sender, EventArgs e)        {            ScrollUp();        }        private void timer2_Tick(object sender, EventArgs e)        {            timer2.Enabled = false;            timer3.Enabled = true;        }        private void Form2_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;        }    }}form1 前台的调用 ：代码using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace MSN{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        private void button1_Click(object sender, EventArgs e)        {             Screen[] screens = Screen.AllScreens;            Screen screen = screens[0];//获取屏幕变量                     Form2 form = new Form2();            form.HeightMax = 120;//窗体滚动的高度            form.WidthMax = 148;//窗体滚动的宽度                         form.ScrollShow();                              }    }}
