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
            {

            }
            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 )
            //    {

            //    }
            //}
          

        }

        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();
          
            
        }
    }
}
