注:本程序是在VS2005基础上写的。


1、如果不想让程序在任务栏中显示,请把窗体的属性ShowInTaskbar设置为false;


2、如果想让程序启动时就最小化,请设置窗体的属性WindowState设置为Minimized。(Minimized 最小化,Normal正常启动,Maximized最大化)


3、拉一个NotifyIcon控件notifyIcon,为控件notifyIcon的属性Icon添加一个icon图标。


4、可以为NotifyIcon加一个ContextMenuStrip右键菜单menu_Notify。


5、本例子禁用了窗体最大化按钮。(设置窗体的属性MaximizeBox的属性为false)


6、主要代码:

#region 私有方法 处理窗体的 显示 隐藏 关闭(退出)

        private void ExitMainForm()

        {

            if (MessageBox.Show("您确定要退出化验数据接收程序吗?", "确认退出", MessageBoxButtons.OKCancel, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2) == DialogResult.OK)

            {

                this.notifyIcon.Visible = false;

                this.Close();

                this.Dispose();

                Application.Exit();

            }

        }


        private void HideMainForm()

        {

            this.Hide();

        }


        private void ShowMainForm()
