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;

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

{

//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.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")

{

msg.Show();
}
} private void Form1_Load(object sender, EventArgs e)
