托盘程序的制作:
1.把NotifyIcon控件拉一个到窗体上,并设置NotifyIcon的Icon(很重要!否则运行后看不到效果)
2.窗体关闭时,将程序最小化到系统托盘上
private void Form1_FormClosing(object sender, FormClosingEventArgs e) { //MessageBox.Show("程序将最小化到系统托盘区"); e.Cancel = true; // 取消关闭窗体 this.Hide(); this.ShowInTaskbar = false;//取消窗体在任务栏的显示 this.notifyIcon1.Visible = true;//显示托盘图标 }
3.放一个上下文菜单,添加几个基本项,"显示主窗体","退出" ,将这个菜单挂到NotifyIcon上
private void menuShow_Click(object sender, EventArgs e) { this.Show(); this.ShowInTaskbar = true; this.notifyIcon1.Visible = false; } private void menuExit_Click(object sender, EventArgs e) { this.Dispose(true); Application.ExitThread(); }
4.左键单击托盘图标时,显示主窗体,右击时当然是弹出上面设置的菜单
private void notifyIcon1_MouseClick(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { this.Show(); this.ShowInTaskbar = true; this.notifyIcon1.Visible = false; } }
防止这个程序同时运行多个
using System; using System.Collections.Generic; using System.Windows.Forms; using System.Threading; namespace LuceneTest { static class Program { /// <summary> /// 应用程序的主入口点。 /// </summary> [STAThread] static void Main() { bool bCreatedNew; Mutex m = new Mutex(false, "Product_Index_Cntvs", out bCreatedNew); if (bCreatedNew) { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } } } }
