软件添加到系统自动启动程序和Winows通知区域

 
1.将软件添加到系统自动启动程序,即写注册表项"HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Run",
C#支持对注册表的编辑，.NET框架在Microsoft.Win32名字空间中提供了两个类来操作注册表：Registry和RegistryKey。这两个类都是密封类不允许被继承。
RegistryKey类中提供了对注册表操作的方法。要注意的是操作注册表必须符合系统权限，否则将会抛出错误。

设置键值的方法原型如下：

 　　public object SetValue(string name,object value);

     示例
     //软件添加到系统启动项中:
     RegistryKey  Reg   =  Registry.LocalMachine.OpenSubKey(@"SOFTWARE/Microsoft/Windows/CurrentVersion/Run",true);  
  
     string   sFilePath   =   Application.ExecutablePath;  
     Reg.SetValue("名字",sFilePath);  

     //删除指定系统启动项:
     Reg.DeleteValue("名字");  

2.C#WinForm里面怎样点击标题栏的最小化按钮后,实现跟MSN一样的效果

#region 最小化到右下角托盘
       

private void ThirdShopList_FormClosing(object sender, FormClosingEventArgs e)
        {
                e.Cancel = true;

                normalToMinimized();
        }

        private void ThirdShopList_Resize(object sender, EventArgs e)
        {
                if (this.WindowState == FormWindowState.Minimized)
                {
                    normalToMinimized();
                }
        }
       
        private void notifyIcon_MouseClick(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                minimizedToNormal();
            }
        }

        private void minimizedToNormal()
        {
            this.Visible = true;

            this.WindowState = FormWindowState.Normal;

            notifyIcon.Visible = false;
        }

        private void normalToMinimized()
        {
            this.WindowState = FormWindowState.Minimized;

            this.Visible = false;

            this.notifyIcon.Visible = true;
        }

        #endregion
