托盘再次打开窗口时出现错误

Question

我做了一个托盘程序，再打开程序时，能正确隐藏窗口。通过托盘打开窗口，点击窗口最小化，重新隐藏窗口，可再通过托盘显示时，窗口只能显示标题栏，这是怎么回事啊？
程序在下面：
        public Form1()
        {
            InitializeComponent();
            Initializenotifyicon();//使用托盘显示初始化
        }
        private void Initializenotifyicon()
        {
            this.MaximizeBox = false;
            this.ShowInTaskbar = false;
            this.WindowState = System.Windows.Forms.FormWindowState.Minimized;
            this.Visible = false;            this.SizeChanged += new EventHandler(Form1_SizeChanged);            TrayIcon = new NotifyIcon();
            TrayIcon.Icon = mNetTrayIcon;
            TrayIcon.Text = "事件监听程序" + "\n" + "版权：北京安图公司";
            TrayIcon.Visible = true;
            TrayIcon.Click += new System.EventHandler(this.OpenForm);            MenuItem[] mnuItms = new MenuItem[3];            mnuItms[0] = new MenuItem();
            mnuItms[0].Text = "打开";
            mnuItms[0].Click += new EventHandler(this.OpenForm);
            mnuItms[0].DefaultItem = true;            mnuItms[1] = new MenuItem("-");            mnuItms[2] = new MenuItem();
            mnuItms[2].Text = "退出系统";
            mnuItms[2].Click += new EventHandler(this.CloseForm);            notifyiconMnu = new ContextMenu(mnuItms);
            TrayIcon.ContextMenu = notifyiconMnu;
        }        private void OpenForm(object sender, System.EventArgs e)
        {
            this.WindowState = System.Windows.Forms.FormWindowState.Normal;
            this.Visible = true;
            this.Show();
        }        private void CloseForm(object sender, System.EventArgs e)
        {
            TrayIcon.Visible = false;
            this.Close();
        }        private void Form1_SizeChanged(object sender, EventArgs e)
        {
            if (this.WindowState == System.Windows.Forms.FormWindowState.Minimized)
            {
                this.ShowInTaskbar = false;
                this.Visible = false;
            }
        }

Answer 1

感觉这个有问题
        private void Form1_SizeChanged(object sender, EventArgs e)
        {
            if (this.WindowState == System.Windows.Forms.FormWindowState.Minimized)
            {
                this.ShowInTaskbar = false;
                this.Visible = false;
            }
        }去掉这个事件看看如果没用得话

Red_angelX:
去掉这个的话，会在windows的左下角显示最小化的窗口，而我想实现的是最小化后，都不显示，只在托盘那里显示图标。

给你参考一下，我封装在类库中的一段，有疑问加我的msn: [email protected]
====================================================================
        /// <summary>
        /// Occurs before the form is closed.
        /// </summary>

        private void MainForm_FormClosing(object sender, FormClosingEventArgs e)
        {
            notifyIcnMainFrm.Visible = this.m_VisibleBalloonInTaskBar;            InitBalloonOfTaskBar();            if (!VisibleBalloonInTaskBar)
            {
                if (m_FormType == TypeOfForms.SubForm)
                    return;
                else if (m_FormType == TypeOfForms.MainForm)
                {
                    Application.Exit();
                    return;
                }
            }            //event while closing forms.
            if (this.WindowState != FormWindowState.Minimized)
            {
                e.Cancel = true;
                this.WindowState = FormWindowState.Minimized;
                this.Hide();
                this.notifyIcnMainFrm.ShowBalloonTip(m_TipPeriod, m_strTipTitle, m_strTipText, ToolTipIcon.Info);
                ResetTextImageOfContentTextMenu(m_conTxtType);
            }
            else  //if (this.WindowState != FormWindowState.Maximized)
            {
                e.Cancel = false;
                Application.Exit();
            }        }
