问题描述
我已经使用electronic + node.js制作了一个桌面应用程序.有时Windows会执行自动更新并重新启动OS.我想防止Windows 10重新启动，直到在软件中保存数据(数据库处于联机状态，因此需要一些时间来存储数据)为止.
I have made a desktop application using electron + node.js.Sometimes Windows does automatic updates and restarts the OS.I want to prevent Windows 10 from restarting until the data is saved (database is online so it takes some time to store data) in software.
现在，我正在使用以下代码来防止窗口关闭.保存数据后，我调用ipcMain.on(''，function())方法并将lockwindow设置为true，然后我调用窗口关闭方法.它通常在正常关闭窗口或使用快捷键关闭窗口时起作用.但是，如果强制关闭或学习/重新启动，则不会发出此事件
Right now, I am using the below code to prevent the window from closing. After data save I am calling ipcMain.on('',function()) method and make lockwindow to true then i am calling window close method.It is working when normally window close or use shortcut keys for a close window.But this event is not emitted in case of force close or studown/restart
mainWindow.on('close', event => {
if (lockWindow) {
mainWindow.webContents.send('save', '');
mainWindow.webContents.once('dom-ready', () => {
mainWindow.webContents.send('save', '');
});
event.preventDefault();
createdialogWindow();
} else
mainWindow = null
})
谢谢.
推荐答案
看看窗口事件，特别是 关闭和之前卸载 .
Have a look at window events, specifically close and beforeunload.
您将只有有限的时间才能使系统重新启动.
You will have only limited time before the system restarts itself anyway.
如果操作系统或用户决定终止您的应用程序，那么无论如何都会发生这种情况(您也可能因不擅长游戏而生气/激怒用户).
If the OS or the user decides to kill your app, this is what is going to happen anyway (you can also upset / anger user for not playing nicely).
最后，您是否希望您的应用程序成为未安装某些关键安全更新的原因?
Lastly, would you like your application to be the reason why some crucial security updates did not install?
