鼠标拖动无边框窗口

1、

        //鼠标拖动

        Point downpoint = new Point();

                   //事件，鼠标按下，获取当前坐标

        private void panel1_MouseDown(object sender, MouseEventArgs e)

        {

            downpoint.X = -e.X;

            downpoint.Y = -e.Y;

        }

                   //事件，鼠标移动，赋值新坐标

        private void panel1_MouseMove(object sender, MouseEventArgs e)

        {

            if (e.Button == MouseButtons.Left)

            {

                Point mouseSet = Control.MousePosition;

                mouseSet.Offset(downpoint.X, downpoint.Y);

                Location = mouseSet;

            }

        }

2、

        int x;

        int y;

                   //事件，鼠标按下，获取当前坐标

        private void Form1_MouseDown(object sender, MouseEventArgs e)

        {

            x = e.X;

            y = e.Y;

        }

                   //事件，鼠标移动，赋值新坐标

        private void Form1_MouseMove(object sender, MouseEventArgs e)

        {

            if (e.Button == System.Windows.Forms.MouseButtons.Left)

            {

                this.Left += e.X - x;

                this.Top += e.Y - y;

            }

        }

Winform中播放声音

1、添加命名空间

         using System.Media;

2、编写代码

         string sound = Application.StartupPath + "/sound/msg.wav";     //音频文件放在exe文件所在目录下的sound文件夹下。Application.StartupPath：程序exe所在的位置。

         SoundPlayer player = new SoundPlayer(sound);

         player.Load();    //把声音加载到内存

         //player.PlayLooping();    //循环播放

         player.Play();    //播放声音

启动外部EXE程序

         System.Diagnostics.Process.Start(@"D:\Program Files(x86)\Tencent\QQ\QQProtect\Bin\QQProtect.exe");
