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

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;

}  

}

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：

            {  
                timer1.Enabled = true;
