只启动一个exe方法: using System; using System.Collections.Generic; using System.Runtime.InteropServices; using System.Windows.Forms; namespace StringToImage { static class Program { [DllImport("user32.dll")] public static extern IntPtr FindWindow(Strin
WinForm如果我们希望一次只打开一个程序,那么我们在程序每次运行的时候都需要检测线程是否存在该程序,如果存在就呼出之前的窗体,C#代码如下: using System; using System.Collections.Generic; using System.Diagnostics; using System.Linq; using System.Reflection; using System.Runtime.InteropServices; using System.Windows.
electron限制只启动一个应用 // ========================================================== // 限制只可以打开一个应用,2.x的文档 // const isSecondInstance = app.makeSingleInstance((commandLine, workingDirectory) => { // // Someone tried to run a second instance, we should focu
本文出自:https://www.cnblogs.com/2186009311CFF/p/10024949.html 在App.xaml.cs填充一下内容,即可实现只允许一个运行,且不解锁屏幕的情况下,重启运行. public partial class App : Application { System.Threading.Mutex mutex; public App() { this.Startup += new StartupEventHandler(App_Startup); thi
一.通过系统事件 1.实现如下: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows.Forms; using System.Threading; using System.Runtime.InteropServices; namespace Example { public class SinglonProgram { #region

using System; using System.Collections.Generic; using System.Windows.Forms; using System.Runtime.InteropServices; using System.Diagnostics; using System.Reflection; namespace AppLed { static class Program { //防止程序运行多个实例的方法有多种,如:通过使用互斥

注意:这是2.x的文档 const {app} = require('electron') let myWindow = null const shouldQuit = app.makeSingleInstance((commandLine, workingDirectory) => { // Someone tried to run a second instance, we should focus our window. if (myWindow) { if (myWindow.isMin
