C#实现一个弹窗监控小程序

一、.实现弹窗淡入淡出等效果即弹窗自动关闭

技术要点：

1.弹窗效果（淡入淡出，自下而上滑入）使用WIN API实现

2.弹出的窗体在一定时间后，自动关闭使用一个timer实现，弹窗开始是，打开timer，到设置时间后，触发timer关闭窗体

代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Media;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace test007
{
    public partial class Message : Form
    {
        public Message()
        {
            InitializeComponent();
        }

        [DllImport("user32")]
        private static extern bool AnimateWindow(IntPtr hwnd, int dwTime, int dwFlags);

        //下面是可用的常量，根据不同的动画效果声明自己需要的
        private const int AW_HOR_POSITIVE = 0x0001;//自左向右显示窗口，该标志可以在滚动动画和滑动动画中使用。使用AW_CENTER标志时忽略该标志
        private const int AW_HOR_NEGATIVE = 0x0002;//自右向左显示窗口，该标志可以在滚动动画和滑动动画中使用。使用AW_CENTER标志时忽略该标志
        private const int AW_VER_POSITIVE = 0x0004;//自顶向下显示窗口，该标志可以在滚动动画和滑动动画中使用。使用AW_CENTER标志时忽略该标志
        private const int AW_VER_NEGATIVE = 0x0008;//自下向上显示窗口，该标志可以在滚动动画和滑动动画中使用。使用AW_CENTER标志时忽略该标志该标志
        private const int AW_CENTER = 0x0010;//若使用了AW_HIDE标志，则使窗口向内重叠；否则向外扩展
        private const int AW_HIDE = 0x10000;//隐藏窗口
        private const int AW_ACTIVE = 0x20000;//激活窗口，在使用了AW_HIDE标志后不要使用这个标志
        private const int AW_SLIDE = 0x40000;//使用滑动类型动画效果，默认为滚动动画类型，当使用AW_CENTER标志时，这个标志就被忽略
        private const int AW_BLEND = 0x80000;//使用淡入淡出效果
        private void Message_Load(object sender, EventArgs e)
        {   
　　　　     timer1.Enabled = true;
            //弹窗
            int x = Screen.PrimaryScreen.WorkingArea.Right - this.Width;
            int y = Screen.PrimaryScreen.WorkingArea.Bottom - this.Height;
            this.Location = new Point(x, y);
            //自下而上弹出窗体
            AnimateWindow(this.Handle, 3000, AW_SLIDE | AW_ACTIVE | AW_VER_NEGATIVE);
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            //关闭窗体，淡入淡出
            AnimateWindow(this.Handle, 1000, AW_BLEND | AW_HIDE);this.Close();
            timer1.Enabled = false;
            this.Close();
            this.Dispose();
        }
    }
}

二、连接数据库

技术要点：

1.连接数据库需要使用Oracle.ManagedDataAccess.dll，具体如何安装，请看前面的文章

2.使用App.config文件来存放数据库连接字符串，方便后面更改

3.OracleHelper辅助类

代码：

App.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
  </startup>
  <appSettings>
    <add key="ConnectionStringSMTP" value="User id=XXX;password=XXX;Data Source=XXX.XXX.XXX.XXX:XXXX/XXX" />
  </appSettings>
</configuration>

获取配置代码

public static string connstrSMTP = ConfigurationManager.AppSettings["ConnectionStringSMTP"];

OracleHelper.cs

using Oracle.ManagedDataAccess.Client;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace test007
{
    public static class OracleHelper
    {
        public static string connstrSMTP = ConfigurationManager.AppSettings["ConnectionStringSMTP"];
        public static string connstrTest = ConfigurationManager.AppSettings["ConnectionStringTest"];

        {
            OracleCommand command = new OracleCommand(storedProcName, connection);
            command.CommandType = CommandType.StoredProcedure;
            foreach (OracleParameter parameter in parameters)
            {
                command.Parameters.Add(parameter);
            }
            return command;
        }
    }
}

三、最小化到托盘

参考：https://www.cnblogs.com/monkey6/p/13188488.html

四、弹窗在所有窗体最前

技术要点：

使用窗体的TopMost属性

代码：

 private void Message_Load(object sender, EventArgs e)
        {
            this.TopMost = true;
            this.TopMost = false;
        }

五、弹窗带声音报警

技术要点：

使用SoundPlayer类

代码：

 private void Message_Load(object sender, EventArgs e)
        {
            //弹窗后播放音乐
            SoundPlayer player = new SoundPlayer();
            player.SoundLocation = @"./alarm1.wav";
            player.Load();
            player.Play();
        }

六、弹出的窗体不获得鼠标焦点，影响用户正常工作

技术要点：重写窗体方法

代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Media;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace test007
{
    public partial class Message : Form
    {
        public Message()
        {
            InitializeComponent();
        }
        //弹窗后不获取鼠标焦点，避免打扰用户的工作
        const int WS_EX_NOACTIVATE = 0x08000000;
        protected override CreateParams CreateParams
        {
            get
            {
                CreateParams cp = base.CreateParams;
                cp.ExStyle |= WS_EX_NOACTIVATE;
                return cp;
            }
        }
    }
}

七、开机自启动

WIN+R快捷键打开运行对话框，输入shell:startup进入开机自启动文件夹，将程式的快捷方式放入其中即可

整体控件，组件及代码

主窗体：

        }

        private void button3_Click(object sender, EventArgs e)
        {
            if (MessageBox.Show("是否确认选择"+comboBox1.Text+"XX？", "XX选择", MessageBoxButtons.OKCancel, MessageBoxIcon.Question) == DialogResult.OK)
            {
                //隐藏窗体
                this.Visible = false;
                //图标显示在托盘区
                notifyIcon1.Visible = true;
                //托盘区气泡提醒
                notifyIcon1.ShowBalloonTip(2000, "提示", "右键图标退出程式", ToolTipIcon.Info);
                if (!timer1.Enabled)
                {
                    timer1.Enabled = true;
                    timer1.Start();
                }
            }
        }

        private void 退出ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (MessageBox.Show("是否确认退出程序？", "退出", MessageBoxButtons.OKCancel, MessageBoxIcon.Question) == DialogResult.OK)
            {
                // 关闭所有的线程
                this.Dispose();
                this.Close();
            }
        }
        private void timer1_Tick(object sender, EventArgs e)
        {
            string sql = "";
            if (comboBox1.Text == "XX")
                sql = "SELECT TITLE,MSG FROM MONITOR";
            else if (comboBox1.Text == "XX")
                sql = "SELECT TITLE,MSG FROM MONITOR";
            else
                sql = "SELECT TITLE,MSG FROM MONITOR";

            DataTable dt = OracleHelper.ExecuteDataTable(OracleHelper.connstrSMTP, CommandType.Text,sql);
            if(dt.Rows.Count > 0)
            {
                Message msg = new Message(dt);
                msg.Show();
            }
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            comboBox1.SelectedIndex = 0;
        }
    }
}
